• Effect of an Intensive Outpatient Program to Augment Primary Care for High-Need Veterans Affairs Patients: A Randomized Clinical Trial. JAMA internal medicine Zulman, D. M., Pal Chee, C., Ezeji-Okoye, S. C., Shaw, J. G., Holmes, T. H., Kahn, J. S., Asch, S. M. 2017; 177 (2): 166-175

  Abstract

  Many organizations are adopting intensive outpatient care programs for high-need patients, yet little is known about their effectiveness in integrated systems with established patient-centered medical homes.To evaluate how augmenting the Veterans Affairs (VA) medical home (Patient Aligned Care Teams [PACT]) with an Intensive Management program (ImPACT) influences high-need patients' costs, health care utilization, and experience.Randomized clinical trial at a single VA facility. Among 583 eligible high-need outpatients whose health care costs or hospitalization risk were in the top 5% for the facility, 150 were randomly selected for ImPACT; the remaining 433 received standard PACT care.The ImPACT multidisciplinary team addressed health care needs and quality of life through comprehensive patient assessments, intensive case management, care coordination, and social and recreational services.Primary difference-in-difference analyses examined changes in health care costs and acute and extended care utilization over a 16-month baseline and 17-month follow-up period. Secondary analyses estimated the intervention's effect on ImPACT participants (using randomization as an instrument) and for patients with key sociodemographic and clinical characteristics. ImPACT participants' satisfaction and activation levels were assessed using responses to quality improvement surveys administered at baseline and 6 months.Of 140 patients assigned to ImPACT, 96 (69%) engaged in the program (mean [SD] age, 68.3 [14.2] years; 89 [93%] male; mean [SD] number of chronic conditions, 10 [4]; 62 [65%] had a mental health diagnosis; 21 [22%] had a history of homelessness). After accounting for program costs, adjusted person-level monthly health care expenditures decreased similarly for ImPACT and PACT patients (difference-in-difference [SE] -$101 [$623]), as did acute and extended care utilization rates. Among respondents to the ImPACT follow-up survey (n = 54 [56% response rate]), 52 (96%) reported that they would recommend the program to others, and pre-post analyses revealed modest increases in satisfaction with VA care (mean [SD] increased from 2.90 [0.72] to 3.16 [0.60]; P = .04) and communication (mean [SD] increased from 2.99 [0.74] to 3.18 [0.60]; P = .03).Intensive outpatient care for high-need patients did not reduce acute care utilization or costs compared with standard VA care, although there were positive effects on experience among patients who participated. Implementing intensive outpatient care programs in integrated settings with well-established medical homes may not prevent hospitalizations or achieve substantial cost savings.clinicaltrials.gov Identifier: NCT02932228.

• How Can eHealth Technology Address Challenges Related to Multimorbidity? Perspectives from Patients with Multiple Chronic Conditions JOURNAL OF GENERAL INTERNAL MEDICINE Zulman, D. M., Jenchura, E. C., Cohen, D. M., Lewis, E. T., Houston, T. K., Asch, S. M. 2015; 30 (8): 1063-1070

  Abstract

  Patient eHealth technology offers potential support for disease self-management, but the value of existing applications for patients with multiple chronic conditions (MCCs) is unclear.To understand self-management and health care navigation challenges that patients face due to MCCs and to identify opportunities to support these patients through new and enhanced eHealth technology.After administering a screening survey, we conducted 10 focus groups of 3-8 patients grouped by age, sex, and common chronic conditions. Patients discussed challenges associated with having MCCs and their use of (and desires from) technology to support self-management. Three investigators used standard content analysis methods to code the focus group transcripts. Emergent themes were reviewed with all collaborators, and final themes and representative quotes were validated with a sample of participants.Fifty-three individuals with ≥3 chronic conditions and experience using technology for health-related purposes.Focus group participants had an average of five chronic conditions. Participants reported using technology most frequently to search for health information (96 %), communicate with health care providers (92 %), track medical information (83 %), track medications (77 %), and support decision-making about treatment (55 %). Three themes emerged to guide eHealth technology development: (1) Patients with MCCs manage a high volume of information, visits, and self-care tasks; (2) they need to coordinate, synthesize, and reconcile health information from multiple providers and about different conditions; (3) their unique position at the hub of multiple health issues requires self-advocacy and expertise. Focus groups identified desirable eHealth resources and tools that reflect these themes.Although patients with multiple health issues use eHealth technology to support self-care for specific conditions, they also desire tools that transcend disease boundaries. By addressing the holistic needs of patients with MCCs, eHealth technology can advance health care from a disease-centered to a patient-centered model.

  Abstract

  Multimorbidity-the presence of multiple chronic conditions in a patient-has a profound impact on health, health care utilization, and associated costs. Definitions of multimorbidity in clinical care and research have evolved over time, initially focusing on a patient's number of comorbidities and the associated magnitude of required care processes, and later recognizing the potential influence of comorbidity characteristics on patient care and outcomes. In this article, we review the relationship between multimorbidity and quality of care, and discuss how this relationship may be mediated by the degree to which conditions interact with one another to generate clinical complexity (comorbidity interrelatedness). Drawing on established theoretical frameworks from cognitive engineering and biomedical informatics, we describe how interactions among conditions result in clinical complexity and may affect quality of care. We discuss how this comorbidity interrelatedness influences the value of existing quality guidelines and performance metrics, and describe opportunities to quantify this construct using data widely available through electronic health records. Incorporating comorbidity interrelatedness into conceptualizations of multimorbidity has the potential to enhance clinical and research efforts that aim to improve care for patients with multiple chronic conditions.

• Patient Interest in Sharing Personal Health Record Information A Web-Based Survey ANNALS OF INTERNAL MEDICINE Zulman, D. M., Nazi, K. M., Turvey, C. L., Wagner, T. H., Woods, S. S., An, L. C. 2011; 155 (12): 805-U46

  Abstract

  Electronic personal health record (PHR) systems are proliferating but largely have not realized their potential for enhancing communication among patients and their network of care providers.To explore preferences about sharing electronic health information among users of the U.S. Department of Veterans Affairs (VA) PHR system, My HealtheVet.Web-based survey of a convenience sample.My HealtheVet Web site from 7 July through 4 October 2010.18 471 users of My HealtheVet.Interest in shared PHR access and preferences about who would receive access, the information that would be shared, and the activities that users would delegate.Survey respondents were predominantly men (92%) and aged 50 to 64 years (51%) or 65 years or older (39%); approximately 39% reported poor or fair health status. Almost 4 of 5 respondents (79%) were interested in sharing access to their PHR with someone outside of their health system (62% with a spouse or partner, 23% with a child, 15% with another family member, and 25% with a non-VA health care provider). Among those who selected a family member other than a spouse or partner, 47% lived apart from the specified person. Preferences about degree of access varied on the basis of the type of information being shared, the type of activity being performed, and the respondent's relationship with the selected person.The survey completion rate was 40.8%. Results might not be generalizable to all My HealtheVet users.In a large survey of PHR users in the VA system, most respondents were interested in sharing access to their electronic health information with caregivers and non-VA providers. Existing and evolving PHR systems should explore secure mechanisms for shared PHR access to improve information exchange among patients and the multiple persons involved in their health care.Veterans Health Administration and The Robert Wood Johnson Foundation Clinical Scholars Program.

• Examining the Evidence: A Systematic Review of the Inclusion and Analysis of Older Adults in Randomized Controlled Trials JOURNAL OF GENERAL INTERNAL MEDICINE Zulman, D. M., Sussman, J. B., Chen, X., Cigolle, C. T., Blaum, C. S., Hayward, R. A. 2011; 26 (7): 783-790

  Abstract

  Due to a shortage of studies focusing on older adults, clinicians and policy makers frequently rely on clinical trials of the general population to provide supportive evidence for treating complex, older patients.To examine the inclusion and analysis of complex, older adults in randomized controlled trials.A PubMed search identified phase III or IV randomized controlled trials published in 2007 in JAMA, NEJM, Lancet, Circulation, and BMJ. Therapeutic interventions that assessed major morbidity or mortality in adults were included. For each study, age eligibility, average age of study population, primary and secondary outcomes, exclusion criteria, and the frequency, characteristics, and methodology of age-specific subgroup analyses were reviewed.Of the 109 clinical trials reviewed in full, 22 (20.2%) excluded patients above a specified age. Almost half (45.6%) of the remaining trials excluded individuals using criteria that could disproportionately impact older adults. Only one in four trials (26.6%) examined outcomes that are considered highly relevant to older adults, such as health status or quality of life. Of the 42 (38.5%) trials that performed an age-specific subgroup analysis, fewer than half examined potential confounders of differential treatment effects by age, such as comorbidities or risk of primary outcome. Trials with age-specific subgroup analyses were more likely than those without to be multicenter trials (97.6% vs. 79.1%, p < 0.01) and funded by industry (83.3% vs. 62.7%, p < 0.05). Differential benefit by age was found in seven trials (16.7%).Clinical trial evidence guiding treatment of complex, older adults could be improved by eliminating upper age limits for study inclusion, by reducing the use of eligibility criteria that disproportionately affect multimorbid older patients, by evaluating outcomes that are highly relevant to older individuals, and by encouraging adherence to recommended analytic methods for evaluating differential treatment effects by age.

• What are the key elements for implementing intensive primary care? A multisite Veterans Health Administration case study HEALTHCARE-THE JOURNAL OF DELIVERY SCIENCE AND INNOVATION Chang, E. T., Raja, P., Stockdale, S. E., Katz, M. L., Zulman, D. M., Eng, J. A., Hedrick, K. H., Jackson, J. L., Pathak, N., Watts, B., Patton, C., Schectman, G., Asch, S. M. 2018; 6 (4): 231–37

  Abstract

  Many integrated health systems and accountable care organizations have turned to intensive primary care programs to improve quality of care and reduce costs for high-need high-cost patients. How best to implement such programs remains an active area of discussion. In 2014, the Veterans Health Administration (VHA) implemented five distinct intensive primary care programs as part of a demonstration project that targeted Veterans at the highest risk for hospitalization. We found that programs evolved over time, eventually converging on the implementation of the following elements: 1) an interdisciplinary care team, 2) chronic disease management, 3) comprehensive patient assessment and evaluation, 4) care and case management, 5) transitional care support, 6) preventive home visits, 7) pharmaceutical services, 8) chronic disease self-management, 9) caregiver support services, 10) health coaching, and 11) advanced care planning. The teams also found that including social workers and mental health providers on the interdisciplinary teams was critical to effectively address psychosocial needs of these complex patients. Having a central implementation coordinator facilitated the convergence of these program features across diverse demonstration sites. In future iterations of these programs, VHA intends to standardize staffing and key features to develop a scalable program that can be disseminated throughout the system.

• Engaging High-Need Patients in Intensive Outpatient Programs: A Qualitative Synthesis of Engagement Strategies. Journal of general internal medicine Zulman, D. M., O'Brien, C. W., Slightam, C., Breland, J. Y., Krauth, D., Nevedal, A. L. 2018

  Abstract

  BACKGROUND: Intensive outpatient programs address the complex medical, social, and behavioral needs of individuals who account for disproportionate healthcare costs. Despite their promise, the impact of these programs is often diminished due to patient engagement challenges (i.e., low rates of patient participation and partnership in care).OBJECTIVE: The objective of this study was to identify intensive outpatient program features and strategies that increase high-need patient engagement in these programs.DESIGN: Qualitative study.PARTICIPANTS: Twenty program leaders and clinicians from 12 intensive outpatient programs in academic, county, Veterans Affairs, community, and private healthcare settings.APPROACH: A questionnaire and semi-structured interviews were used to identify common barriers to patient engagement in intensive outpatient programs and strategies employed by programs to address these challenges. We used content analysis methods to code patient engagement barriers and strategies and to identify program features that facilitate patient engagement.KEY RESULTS: The most common barriers to patient engagement in intensive outpatient programs included physical symptoms/limitations, mental illness, care fragmentation across providers and services, isolation/lack of social support, financial insecurity, and poor social and neighborhood conditions. Patient engagement strategies included concrete services to support communication and use of recommended services, activities to foster patient trust and relationships with program staff, and counseling to build insight and problem-solving capabilities. Program features that were identified as enhancing engagement efforts included: 1) multidisciplinary teams with diverse skills, knowledge, and personalities to facilitate relationship building; 2) adequate staffing and resources to handle the demands of high-need patients; and 3) a philosophy that permitted flexibility and patient-centeredness.CONCLUSIONS: Promising clinical, interpersonal, and population-based approaches to engaging high-need patients frequently deviate from standard practice and require creative and proactive staff with adequate time, resources, and flexibility to address patients' needs on patients' terms.

• Patient-Centered Medical Home Implementation and Improved Chronic Disease Quality: A Longitudinal Observational Study HEALTH SERVICES RESEARCH Rosland, A., Wong, E., Maciejewski, M., Zulman, D., Piegari, R., Fihn, S., Nelson, K. 2018; 53 (4): 2503–22

  Abstract

  To examine associations between clinics' extent of patient-centered medical home (PCMH) implementation and improvements in chronic illness care quality.Data from 808 Veterans Health Administration (VHA) primary care clinics nationwide implementing the Patient Aligned Care Teams (PACT) PCMH initiative, begun in 2010.Clinic-level longitudinal observational study of clinics that received training and resources to implement PACT. Clinics varied in the extent they had PACT components in place by 2012.Clinical care quality measures reflecting intermediate outcomes and care processes related to coronary artery disease (CAD), diabetes, and hypertension care were collected by manual chart review at each VHA facility from 2009 to 2013.In adjusted models containing 808 clinics, the 77 clinics with the most PACT components in place had significantly larger improvements in five of seven chronic disease intermediate outcome measures (e.g., BP < 160/100 in diabetes), ranging from 1.3 percent to 5.2 percent of the patient population meeting measures, and two of eight process measures (HbA1c measurement, LDL measurement in CAD) than the 69 clinics with the least PACT components. Clinics with moderate levels of PACT components showed few significantly larger improvements than the lowest PACT clinics.Veterans Health Administration primary care clinics with the most PCMH components in place in 2012 had greater improvements in several chronic disease quality measures in 2009-2013 than the lowest PCMH clinics.

• Impact of Primary Care Intensive Management on High-Risk Veterans' Costs and Utilization A Randomized Quality Improvement Trial ANNALS OF INTERNAL MEDICINE Yoon, J., Chang, E., Rubenstein, L., Park, A., Zulman, D. M., Stockdale, S., Ong, M. K., Atkins, D., Schectman, G., Asch, S. M. 2018; 168 (12): 846-+

  Abstract

  Primary care models that offer comprehensive, accessible care to all patients may provide insufficient resources to meet the needs of patients with complex conditions who have the greatest risk for hospitalization.To assess whether augmenting usual primary care with team-based intensive management lowers utilization and costs for high-risk patients.Randomized quality improvement trial. (ClinicalTrials.gov: NCT03100526).5 U.S. Department of Veterans Affairs (VA) medical centers.Primary care patients at high risk for hospitalization who had a recent acute care episode.Locally tailored intensive management programs providing care coordination, goals assessment, health coaching, medication reconciliation, and home visits through an interdisciplinary team, including a physician or nurse practitioner, a nurse, and psychosocial experts.Utilization and costs (including intensive management program expenses) 12 months before and after randomization.2210 patients were randomly assigned, 1105 to intensive management and 1105 to usual care. Patients had a mean age of 63 years and an average of 7 chronic conditions; 90% were men. Of the patients assigned to intensive management, 487 (44%) received intensive outpatient care (that is, ≥3 encounters in person or by telephone) and 204 (18%) received limited intervention. From the pre- to postrandomization periods, mean inpatient costs decreased more for the intensive management than the usual care group (-$2164 [95% CI, -$7916 to $3587]). Outpatient costs increased more for the intensive management than the usual care group ($2636 [CI, $524 to $4748]), driven by greater use of primary care, home care, telephone care, and telehealth. Mean total costs were similar in the 2 groups before and after randomization.Sites took up to several months to contact eligible patients, limiting the time between treatment and outcome assessment. Only VA costs were assessed.High-risk patients with access to an intensive management program received more outpatient care with no increase in total costs.Veterans Health Administration Primary Care Services.

• An operations-partnered evaluation of care redesign for high-risk patients in the Veterans Health Administration (VHA): Study protocol for the PACT Intensive Management (PIM) randomized quality improvement evaluation CONTEMPORARY CLINICAL TRIALS Chang, E. T., Zulman, D. M., Asch, S. M., Stockdale, S. E., Yoon, J., Ong, M. K., Lee, M., Simon, A., Atkins, D., Schectman, G., Kirsh, S. R., Rubenstein, L. V., PIM Executive Comm Demonstrati 2018; 69: 65–75

  Abstract

  Patient-centered medical homes have made great strides providing comprehensive care for patients with chronic conditions, but may not provide sufficient support for patients at highest risk for acute care use. To address this, the Veterans Health Administration (VHA) initiated a five-site demonstration project to evaluate the effectiveness of augmenting the VA's Patient Aligned Care Team (PACT) medical home with PACT Intensive Management (PIM) teams for Veterans at highest risk for hospitalization.Researchers partnered with VHA leadership to design a mixed-methods prospective multi-site evaluation that met leadership's desire for a rigorous evaluation conducted as quality improvement rather than research. We conducted a randomized QI evaluation and assigned high-risk patients to participate in PIM and compared them with high-risk Veterans receiving usual care through PACT. The summative evaluation examines whether PIM: 1) decreases VHA emergency department and hospital use; 2) increases satisfaction with VHA care; 3) decreases provider burnout; and 4) generates positive returns on investment. The formative evaluation aims to support improved care for high-risk patients at demonstration sites and to inform future initiatives for high-risk patients. The evaluation was reviewed by representatives from the VHA Office of Research and Development and the Office of Research Oversight and met criteria for quality improvement.VHA aims to function as a learning organization by rapidly implementing and rigorously testing QI innovations prior to final program or policy development. We observed challenges and opportunities in designing an evaluation consistent with QI standards and operations priorities, while also maintaining scientific rigor.This trial was retrospectively registered at ClinicalTrials.gov on April 3, 2017: NCT03100526. Protocol v1, FY14-17.

• Development of a web-based toolkit to support improvement of care coordination in primary care TRANSLATIONAL BEHAVIORAL MEDICINE Ganz, D. A., Barnard, J. M., Smith, N. Y., Miake-Lye, I. M., Delevan, D. M., Simon, A., Rose, D. E., Stockdale, S. E., Chang, E. T., Noel, P. H., Finley, E. P., Lee, M. L., Zulman, D. M., Cordasco, K. M., Rubenstein, L. V. 2018; 8 (3): 492–502

  Abstract

  Promising practices for the coordination of chronic care exist, but how to select and share these practices to support quality improvement within a healthcare system is uncertain. This study describes an approach for selecting high-quality tools for an online care coordination toolkit to be used in Veterans Health Administration (VA) primary care practices. We evaluated tools in three steps: (1) an initial screening to identify tools relevant to care coordination in VA primary care, (2) a two-clinician expert review process assessing tool characteristics (e.g. frequency of problem addressed, linkage to patients' experience of care, effect on practice workflow, and sustainability with existing resources) and assigning each tool a summary rating, and (3) semi-structured interviews with VA patients and frontline clinicians and staff. Of 300 potentially relevant tools identified by searching online resources, 65, 38, and 18 remained after steps one, two and three, respectively. The 18 tools cover five topics: managing referrals to specialty care, medication management, patient after-visit summary, patient activation materials, agenda setting, patient pre-visit packet, and provider contact information for patients. The final toolkit provides access to the 18 tools, as well as detailed information about tools' expected benefits, and resources required for tool implementation. Future care coordination efforts can benefit from systematically reviewing available tools to identify those that are high quality and relevant.

• Engaging high-risk patients in intensive care coordination programs: the engagement through CARInG framework TRANSLATIONAL BEHAVIORAL MEDICINE O'Brien, C. W., Breland, J. Y., Slightam, C., Nevedal, A., Zulman, D. M. 2018; 8 (3): 351–56

  Abstract

  Intensive outpatient care programs (IOCPs) have shown promise for high-risk patients who account for disproportionate acute care utilization and costs. These programs typically address medical, behavioral, and social needs through intensive case management, health care navigation, coordination, and access to a range of social and community services. However, the value of these programs is often limited by patient engagement challenges (i.e., difficulty engaging patients in self-care, decision-making, and follow-up with recommended services). The purpose of this study was to develop a framework for engaging high-risk patients with complex medical, behavioral, and social needs in IOCPs. We conducted a qualitative study with 20 leaders and clinicians (e.g., physicians, nurses, psychologists, case workers) from 12 IOCPs affiliated with diverse settings (academic hospitals, county healthcare systems, Veterans Affairs facilities, community health centers, and private health systems). After completing a brief survey, participants were asked to describe how their program conceptualizes patient engagement and to describe characteristics of highly engaged patients. We used conventional content analysis methods to analyze qualitative data. Three domains of engagement were identified and are summarized in the Engagement Through CARInG Framework: Communication and actions to improve health; Relationships built on trust in IOCP staff; and Insight and goal-setting ability. Qualitative findings illustrate the spectrum and interrelatedness of these domains. The Engagement Through CARInG Framework can guide interventions that aim to enhance self-care and improve care coordination for high-risk patients with complex medical, behavioral, and social needs.

• A Natural Language Processing System That Links Medical Terms in Electronic Health Record Notes to Lay Definitions: System Development Using Physician Reviews JOURNAL OF MEDICAL INTERNET RESEARCH Chen, J., Druhl, E., Ramesh, B., Houston, T. K., Brandt, C. A., Zulman, D. M., Vimalananda, V. G., Malkani, S., Yu, H. 2018; 20 (1): e26

  Abstract

  Many health care systems now allow patients to access their electronic health record (EHR) notes online through patient portals. Medical jargon in EHR notes can confuse patients, which may interfere with potential benefits of patient access to EHR notes.The aim of this study was to develop and evaluate the usability and content quality of NoteAid, a Web-based natural language processing system that links medical terms in EHR notes to lay definitions, that is, definitions easily understood by lay people.NoteAid incorporates two core components: CoDeMed, a lexical resource of lay definitions for medical terms, and MedLink, a computational unit that links medical terms to lay definitions. We developed innovative computational methods, including an adapted distant supervision algorithm to prioritize medical terms important for EHR comprehension to facilitate the effort of building CoDeMed. Ten physician domain experts evaluated the user interface and content quality of NoteAid. The evaluation protocol included a cognitive walkthrough session and a postsession questionnaire. Physician feedback sessions were audio-recorded. We used standard content analysis methods to analyze qualitative data from these sessions.Physician feedback was mixed. Positive feedback on NoteAid included (1) Easy to use, (2) Good visual display, (3) Satisfactory system speed, and (4) Adequate lay definitions. Opportunities for improvement arising from evaluation sessions and feedback included (1) improving the display of definitions for partially matched terms, (2) including more medical terms in CoDeMed, (3) improving the handling of terms whose definitions vary depending on different contexts, and (4) standardizing the scope of definitions for medicines. On the basis of these results, we have improved NoteAid's user interface and a number of definitions, and added 4502 more definitions in CoDeMed.Physician evaluation yielded useful feedback for content validation and refinement of this innovative tool that has the potential to improve patient EHR comprehension and experience using patient portals. Future ongoing work will develop algorithms to handle ambiguous medical terms and test and evaluate NoteAid with patients.

• Adjustment for Variable Adherence Under Hierarchical Structure: Instrumental Variable Modeling Through Compound Residual Inclusion MEDICAL CARE Holmes, T. H., Zulman, D. M., Kushida, C. A. 2017; 55 (12): E120–E130

  Abstract

  Variable adherence to assigned conditions is common in randomized clinical trials.A generalized modeling framework under longitudinal data structures is proposed for regression estimation of the causal effect of variable adherence on outcome, with emphasis upon adjustment for unobserved confounders.A nonlinear, nonparametric random-coefficients modeling approach is described. Estimates of local average treatment effects among compliers can be obtained simultaneously for all assigned conditions to which participants are randomly assigned within the trial. Two techniques are combined to address time-varying and time-invariant unobserved confounding-residual inclusion and nonparametric random-coefficients modeling. Together these yield a compound, 2-stage residual inclusion, instrumental variables model.The proposed method is illustrated through a set of simulation studies to examine small-sample bias and in application to neurocognitive outcome data from a large, multicenter, randomized clinical trial in sleep medicine for continuous positive airway pressure treatment of obstructive sleep apnea.Results of simulation studies indicate that, relative to a standard comparator, the proposed estimator reduces bias in estimates of the causal effect of variable adherence. Bias reductions were greatest at higher levels of residual variance and when confounders were time varying.The proposed modeling framework is flexible in the distributions of outcomes that can be modeled, applicable to repeated measures longitudinal structures, and provides effective reduction of bias due to unobserved confounders.

• The Shared Health Appointments and Reciprocal Enhanced Support (SHARES) study: study protocol for a randomized trial. Trials Heisler, M., Burgess, J., Cass, J., Chardos, J. F., Guirguis, A. B., Jeffery, S. M., Strohecker, L. A., Tremblay, A. S., Wu, W., Zulman, D. M. 2017; 18 (1): 239-?

  Abstract

  Diabetes shared medical appointments (SMAs) and reciprocal peer support programs have been found in efficacy trials to help adults with diabetes improve their self-management and achieve short-term gains in clinical and patient-centered outcomes. In order to translate this evidence to system-level interventions, there is a need for large-scale, pragmatic trials that examine the effectiveness, implementation, and costs of SMAs and reciprocal peer support across diverse settings.The Shared Health Appointments and Reciprocal Enhanced Support (SHARES) study is a multisite, cluster randomized trial that is evaluating the effectiveness and implementation of SMAs with and without an additional reciprocal Peer-to-Peer (P2P) support program, when compared to usual care. The P2P program comprises periodic peer support group sessions and telephone contact between SMA participant pairs to promote more effective diabetes self-management. We will examine outcomes across three different treatment groups: (1) SMAs, (2) SMAs plus P2P, and (3) usual care. We will collect and analyze data over a 2.5-year implementation period at five geographically diverse Veterans Affairs (VA) health systems. The primary outcome is the relative change in hemoglobin A1c over time. Secondary outcomes are changes in systolic blood pressure, antihypertensive medication use, statin use, and insulin initiation over the study period. The unit of analysis is the individual, adjusted by the individual's SMA group (the cluster). We will use mixed methods to rigorously evaluate processes and costs of implementing these programs in each of the clinic settings.We hypothesize that patients will experience improved outcomes immediately following participation in SMAs and that augmenting SMAs with reciprocal peer support will help to maintain these gains over time. The results of this study will be among the first to examine the effects of diabetes SMAs alone and in conjunction with P2P in a range of real-life clinical settings. In addition, the study will provide important information on contextual factors associated with successful program implementation.ClinicalTrials.gov, ID: NCT02132676 . Registered on 21 August 2013.

This study examined the impact of an insurer's lifestyle modification program on healthcare costs of obese individuals.This nonrandomized comparative effectiveness study evaluated changes in healthcare costs for participants in two incentivized programs, an Internet-mediated pedometer-based walking program (WalkingSpree, n=7,594) and an in-person weight-loss program (Weight Watchers, n=5,764). The primary outcome was the change in total healthcare costs from the baseline year to the year after program participation. Data were collected from 2009 to 2011 and the analysis was done in 2014-2015.After 1 year, unadjusted mean costs decreased in both programs, with larger decreases for Weight Watchers participants than WalkingSpree participants (-$1,055.39 vs -$577.10, p=0.019). This difference was driven by higher rates of women in Weight Watchers, higher baseline total costs among women, and a greater decrease in costs for women in Weight Watchers (-$1,037.60 vs -$388.50, p=0.014). After adjustment for baseline costs, there were no differences by program or gender.Comparable cost reductions in both programs suggest that employers may want to offer more than one choice of incentivized wellness program with monitoring to meet the diverse needs of employees.

• "I had to change so much in my life to live with my new limitations": Multimorbid patients' descriptions of their most bothersome chronic conditions. Chronic illness Slightam, C. A., Brandt, K., Jenchura, E. C., Lewis, E. T., Asch, S. M., Zulman, D. M. 2017: 1742395317699448-?

  Abstract

  Objective To characterize diseases that are described as most bothersome by individuals with multiple chronic conditions and to identify themes that characterize their experiences with their most bothersome condition. Methods In a survey of patients at an academic center and a Veterans Affairs hospital, we asked individuals with multiple chronic conditions to identify their most bothersome chronic condition and describe why it is challenging. Standard content analysis methods were used to code responses and identify themes reflecting characteristics of most bothersome conditions. Results The most commonly cited bothersome conditions were chronic pain (52%), diabetes (43%), post-traumatic stress disorder (25%), heart failure (24%), and lung problems (20%). Conditions were described as most bothersome due to: (a) impact on function and quality of life (e.g. active symptoms, activity limitations), (b) health consequences or sequelae (e.g. risk of complications), and (c) challenges associated with treatment or self-management. Patterns of theme dominance varied for conditions with different characteristics. Discussion The conditions that patients with multiple chronic conditions identify as most bothersome vary depending on individuals' diseases and their health-related preferences and priorities. Ascertaining patients' most bothersome conditions and associated challenges, stress, and frustrations may help ensure that management decisions are aligned with patient preferences and priorities.

• Alternative Strategies to Inpatient Hospitalization for Acute Medical Conditions: A Systematic Review. JAMA internal medicine Conley, J., O'Brien, C. W., Leff, B. A., Bolen, S., Zulman, D. 2016; 176 (11): 1693-1702

  Abstract

  Determining innovative approaches that better align health needs to the appropriate setting of care remains a key priority for the transformation of US health care; however, to our knowledge, no comprehensive assessment exists of alternative management strategies to hospital admission for acute medical conditions.To examine the effectiveness, safety, and cost of managing acute medical conditions in settings outside of a hospital inpatient unit.MEDLINE, Scopus, CINAHL, and the Cochrane Database of Systematic Reviews (January 1995 to February 2016) were searched for English-language systematic reviews that evaluated alternative management strategies to hospital admission. Two investigators extracted data independently on trial design, eligibility criteria, clinical outcomes, patient experience, and health care costs. The quality of each review was assessed using the revised AMSTAR tool (R-AMSTAR) and the strength of evidence from primary studies was graded according to the Oxford Centre for Evidence-Based Medicine.Twenty-five systematic reviews (representing 123 primary studies) met inclusion criteria. For outpatient management strategies, several acute medical conditions had no significant difference in mortality, disease-specific outcomes, or patient satisfaction compared with inpatient admission. For quick diagnostic units, the evidence was more limited but did demonstrate low mortality rates and high patient satisfaction. For hospital-at-home, a variety of acute medical conditions had mortality rates, disease-specific outcomes, and patient and caregiver satisfaction that were either improved or no different compared with inpatient admission. For observation units, several acute medical conditions were found to have no difference in mortality, a decreased length of stay, and improved patient satisfaction compared to inpatient admission; results for some conditions were more limited. Across all alternative management strategies, cost data were heterogeneous but showed near-universal savings when assessed.For low-risk patients with a range of acute medical conditions, evidence suggests that alternative management strategies to inpatient care can achieve comparable clinical outcomes and patient satisfaction at lower costs. Further study and application of such opportunities for health system redesign is warranted.

• How Veterans With Post-Traumatic Stress Disorder and Comorbid Health Conditions Utilize eHealth to Manage Their Health Care Needs: A Mixed-Methods Analysis JOURNAL OF MEDICAL INTERNET RESEARCH Whealin, J. M., Jenchura, E. C., Wong, A. C., Zulman, D. M. 2016; 18 (10): 175-190

  Abstract

  Mental health conditions are prevalent among US veterans and pose a number of self-management and health care navigation challenges. Post-Traumatic Stress Disorder (PTSD) with comorbid chronic medical conditions (CMCs) is especially common, in both returning Iraq or Afghanistan and earlier war-era veterans. Patient-facing electronic health (eHealth) technology may offer innovative strategies to support these individuals' needs.This study was designed to identify the types of eHealth tools that veterans with PTSD and comorbid CMCs use, understand how they currently use eHealth technology to self-manage their unique health care needs, and identify new eHealth resources that veterans feel would empower them to better manage their health care.A total of 119 veterans with PTSD and at least one CMC who have used the electronic personal health record system of the US Department of Veterans Affairs (VA) responded to a mailed survey about their chronic conditions and preferences related to the use of technology. After the survey, 2 focus groups, stratified by sex, were conducted with a subgroup of patients to explore how veterans with PTSD and comorbid CMCs use eHealth technology to support their complex health care needs. Focus groups were transcribed verbatim and analyzed using standard content analysis methods for coding textual data, guided by the "Fit between Individual, Task, and Technology" framework.Survey respondents had a mean age of 64.0 (SD 12.0) years, 85.1% (97/114) were male, 72.4% (84/116) were white, and 63.1% (70/111) had an annual household income of < US $50,000. Mean score on a measure of eHealth literacy was 27.7 (SD 9.8). Of the respondents, 44.6% (50/112) used health-related technology 1 to 3 times per month and 21.4% (24/112) used technology less than once per month. Veterans reported using technology most often to search for health information (78.9%, 90/114), communicate with providers (71.1%, 81/114), and track medications (64.9%, 74/114). Five major themes emerged that describe how eHealth technology influences veterans with PTSD and comorbid CMCs: (1) interactions with social support, (2) condition management, (3) access to and communication with providers, (4) information access, and (5) coordination of care.The "Fit between Individual, Task, and Technology" model provided a useful framework to examine the clinical tasks that arose for veterans and their resourceful adoption of eHealth tools. This study suggests that veterans who use the Web are eager to incorporate eHealth technology into their care and self-management activities. Findings illustrate a number of ways in which the VA and eHealth technology developers can refine existing applications, develop new resources, and better promote tools that address challenges experienced by veterans with PTSD and comorbid CMCs.

• Patient-Facing Mobile Apps to Treat High-Need, High-Cost Populations: A Scoping Review JMIR MHEALTH AND UHEALTH Singh, K., Drouin, K., Newmark, L. P., Filkins, M., Silvers, E., Bain, P. A., Zulman, D. M., Lee, J., Rozenblum, R., Pabo, E., Landman, A., Klinger, E. V., Bates, D. W. 2016; 4 (4)

  Abstract

  Self-management is essential to caring for high-need, high-cost (HNHC) populations. Advances in mobile phone technology coupled with increased availability and adoption of health-focused mobile apps have made self-management more achievable, but the extent and quality of the literature supporting their use is not well defined.The purpose of this review was to assess the breadth, quality, bias, and types of outcomes measured in the literature supporting the use of apps targeting HNHC populations.Data sources included articles in PubMed and MEDLINE (National Center for Biotechnology Information), EMBASE (Elsevier), the Cochrane Central Register of Controlled Trials (EBSCO), Web of Science (Thomson Reuters), and the NTIS (National Technical Information Service) Bibliographic Database (EBSCO) published since 2008. We selected studies involving use of patient-facing iOS or Android mobile health apps. Extraction was performed by 1 reviewer; 40 randomly selected articles were evaluated by 2 reviewers to assess agreement.Our final analysis included 175 studies. The populations most commonly targeted by apps included patients with obesity, physical handicaps, diabetes, older age, and dementia. Only 30.3% (53/175) of the apps studied in the reviewed literature were identifiable and available to the public through app stores. Many of the studies were cross-sectional analyses (42.9%, 75/175), small (median number of participants=31, interquartile range 11.0-207.2, maximum 11,690), or performed by an app's developers (61.1%, 107/175). Of the 175 studies, only 36 (20.6%, 36/175) studies evaluated a clinical outcome.Most apps described in the literature could not be located on the iOS or Android app stores, and existing research does not robustly evaluate the potential of mobile apps. Whereas apps may be useful in patients with chronic conditions, data do not support this yet. Although we had 2-3 reviewers to screen and assess abstract eligibility, only 1 reviewer abstracted the data. This is one limitation of our study. With respect to the 40 articles (22.9%, 40/175) that were assigned to 2 reviewers (of which 3 articles were excluded), inter-rater agreement was significant on the majority of items (17 of 30) but fair-to-moderate on others.

  Abstract

  To inform the development of a data-driven measure of quality care for individuals with multiple chronic conditions (MCCs) derived from an electronic health record (EHR).Qualitative study using focus groups, interactive webinars, and a modified Delphi process.Research department within an integrated delivery system.The webinars and Delphi process included 17 experts in clinical geriatrics and primary care, health policy, quality assessment, health technology, and health system operations. The focus group included 10 individuals aged 70-87 with three to six chronic conditions selected from a random sample of individuals aged 65 and older with three or more chronic medical conditions.Through webinars and the focus group, input was solicited on constructs representing high-quality care for individuals with MCCs. A working list was created of potential measures representing these constructs. Using a modified Delphi process, experts rated the importance of each possible measure and the feasibility of implementing each measure using EHR data.High-priority constructs reflected processes rather than outcomes of care. High-priority constructs that were potentially feasible to measure included assessing physical function, depression screening, medication reconciliation, annual influenza vaccination, outreach after hospital admission, and documented advance directives. High-priority constructs that were less feasible to measure included goal setting and shared decision-making, identifying drug-drug interactions, assessing social support, timely communication with patients, and other aspects of good customer service. Lower-priority domains included pain assessment, continuity of care, and overuse of screening or laboratory testing.High-quality MCC care should be measured using meaningful process measures rather than outcomes. Although some care processes are currently extractable from electronic data, capturing others will require adapting and applying technology to encourage holistic, person-centered care.

  Abstract

  Adolescents and young adults (AYA) with serious chronic illnesses face costly and dangerous gaps in care as they transition from pediatric to adult health systems. New, financially sustainable approaches to transition are needed to close these gaps. We designed a new transition model for adolescents and young adults with a variety of serious chronic conditions. Our explicit goal was to build a model that would improve the value of care for youth 15-25 years of age undergoing this transition. The design process incorporated a review, analysis, and synthesis of relevant clinical and health services research; stakeholder interviews; and observations of high-performing healthcare systems. We identified three major categories of solutions for a safer and lower cost transition to adult care: (1) building and supporting self-management during the critical transition; (2) engaging receiving care; and (3) providing checklist-driven guide services during the transition. We propose that implementation of a program with these interventions would have a positive impact on all three domains of the triple aim - improving health, improving the experience of care, and reducing per capita healthcare cost. The transition model provides a general framework as well as suggestions for specific interventions. Pilot tests to assess the model's ease of implementation, clinical effects, and financial impact are currently underway.

• Key ingredients for implementing intensive outpatient programs within patient-centered medical homes: A literature review and qualitative analysis. Healthcare (Amsterdam, Netherlands) Breland, J. Y., Asch, S. M., Slightam, C., Wong, A., Zulman, D. M. 2016; 4 (1): 22-29

  Abstract

  Intensive outpatient programs aim to transform care while conserving resources for high-need, high-cost patients, but little is known about factors that influence their implementation within patient-centered medical homes (PCMHs).In this mixed-methods study, we reviewed the literature to identify factors affecting intensive outpatient program implementation, then used semi-structured interviews to determine how these factors influenced the implementation of an intensive outpatient program within the Veterans Affairs' (VA) PCMH. Interviewees included facility leadership and clinical staff who were involved in a pilot Intensive Management Patient Aligned Care Team (ImPACT) intervention for high-need, high-cost VA PCMH patents. We classified implementation factors in the literature review and qualitative analysis using the Consolidated Framework for Implementation Research (CFIR).The literature review (n=9 studies) and analyses of interviews (n=15) revealed key implementation factors in three CFIR domains. First, the Inner Setting (i.e., the organizational and PCMH environment), mostly enabled implementation through a culture of innovation, good networks and communication, and positive tension for change. Second, Characteristics of Individuals, including creativity, flexibility, and interpersonal skills, allowed program staff to augment existing PCMH services. Finally, certain Intervention Characteristics (e.g., adaptability) enabled implementation, while others (e.g., complexity) generated implementation barriers.Resources and structural features common to PCMHs can facilitate implementation of intensive outpatient programs, but program success is also dependent on staff creativity and flexibility, and intervention adaptations to meet patient and organizational needs.Established PCMHs likely provide resources and environments that permit accelerated implementation of intensive outpatient programs.V.

• Adjustment for Variable Adherence Under Hierarchical Structure: Instrumental Variable Modeling Through Compound Residual Inclusion. Medical care Holmes, T. H., Zulman, D. M., Kushida, C. A. 2016: -?

  Abstract

  Variable adherence to assigned conditions is common in randomized clinical trials.A generalized modeling framework under longitudinal data structures is proposed for regression estimation of the causal effect of variable adherence on outcome, with emphasis upon adjustment for unobserved confounders.A nonlinear, nonparametric random-coefficients modeling approach is described. Estimates of local average treatment effects among compliers can be obtained simultaneously for all assigned conditions to which participants are randomly assigned within the trial. Two techniques are combined to address time-varying and time-invariant unobserved confounding-residual inclusion and nonparametric random-coefficients modeling. Together these yield a compound, 2-stage residual inclusion, instrumental variables model.The proposed method is illustrated through a set of simulation studies to examine small-sample bias and in application to neurocognitive outcome data from a large, multicenter, randomized clinical trial in sleep medicine for continuous positive airway pressure treatment of obstructive sleep apnea.Results of simulation studies indicate that, relative to a standard comparator, the proposed estimator reduces bias in estimates of the causal effect of variable adherence. Bias reductions were greatest at higher levels of residual variance and when confounders were time varying.The proposed modeling framework is flexible in the distributions of outcomes that can be modeled, applicable to repeated measures longitudinal structures, and provides effective reduction of bias due to unobserved confounders.

• Health Care Utilization Patterns Among High-Cost VA Patients With Mental Health Conditions. Psychiatric services Hunter, G., Yoon, J., Blonigen, D. M., Asch, S. M., Zulman, D. M. 2015; 66 (9): 952-958

  Abstract

  To inform development of intensive management programs for high-cost patients, this study investigated the relationship between psychiatric diagnoses and patterns of health care utilization among high-cost patients in the Department of Veterans Affairs (VA) health care system.The costliest 5% of patients who received care in the VA in fiscal year 2010 were assigned to five mutually exclusive hierarchical groups on the basis of diagnosis codes: no mental health condition, serious mental illness, substance use disorder, posttraumatic stress disorder (PTSD), and depression. Multivariable linear regression was used to examine associations between diagnostic groups and use of mental health and non-mental health care and costs of care, with adjustment for sociodemographic characteristics. The proportion of costs generated by mental health care was estimated for each group.Among 261,515 high-cost VA patients, rates of depression, substance use disorder, PTSD, and serious mental illness were 29%, 20%, 17%, and 13%, respectively. Individuals in the serious mental illness and substance use disorder groups were younger and had fewer chronic general medical conditions and higher adjusted rates of mental health care utilization; they also had a greater proportion of costs generated by mental health care (41% and 31%, respectively) compared with individuals in the PTSD and depression groups (18% and 11%, respectively).Optimal management of high-risk, high-cost patients may require stratification by psychiatric diagnoses, with integrated care models for patients with multiple chronic conditions and comorbid mental health conditions and intensive mental health services for patients whose primary needs stem from mental health conditions.

• Association Between Acute Medical Exacerbations and Consuming or Producing Web-Based Health Information: Analysis From Pew Survey Data JOURNAL OF MEDICAL INTERNET RESEARCH Gidwani, R., Zulman, D. 2015; 17 (6)

  Abstract

  The Internet is an increasingly important resource for individuals who seek information from both health professionals and peers. While the demographic and health characteristics of persons who use health information technology has been well described, less is known about the relationship between these health characteristics and level of engagement with health information technology. Even less is known about whether persons who produce Web-based health information differ in health status from persons who consume such content.We explored the health characteristics of persons who engage with the Internet for the purposes of consuming or producing Web-based health information, and specifically, whether healthier versus sicker persons engage with health information technology in different ways.We analyzed data from the 2012 Pew Health survey, a landline and cell phone survey of 3104 adults in the United States. Using multiple logistic regression with sampling weights, we examined the association between sociodemographic and health characteristics and the consumption or production of Web-based health information. Sociodemographic variables included age, sex, race, and education. Health characteristics included self-reported health status, presence of chronic condition(s), and having an acute medical exacerbation. Acute medical exacerbations were defined as an emergency department visit, hospitalization, or other serious medical emergency in the last 12 months.The majority of the sample reported good or excellent health (79.7%), although 50.3% reported having at least one chronic condition. About a fifth (20.2%) of the sample experienced an acute medical exacerbation in the past year. Education was the sociodemographic characteristic most strongly associated with consuming Web-based health information. The strongest health-related predictors of consuming Web-based health information were an acute medical exacerbation (OR 2.39, P<.001) and having a chronic condition (OR 1.54, P=.007). Having an acute medical exacerbation was the only predictor of producing Web-based health information (OR 1.97, P=.003). All participants, regardless of health status, were most interested in Web-based health information regarding diseases or medical problems. However, persons with acute medical exacerbations were more likely to seek Web-based health information regarding medical tests, procedures, and drugs compared to persons without acute medical exacerbations.Producers of Web-based health information differ from consumers of this information in important health characteristics that could skew the content of peer-generated Web-based health information and overrepresent the experiences of persons with acute medical exacerbations. Providers may have a role to play in directing patients towards high-quality, easy-to-understand online information, especially information regarding treatments and procedures.

• Racial Differences in Chronic Conditions and Sociodemographic Characteristics Among High-Utilizing Veterans. Journal of racial and ethnic health disparities Breland, J. Y., Chee, C. P., Zulman, D. M. 2015; 2 (2): 167-175

  Abstract

  African-Americans are disproportionally represented among high-risk, high-utilizing patients. To inform program development for this vulnerable population, the current study describes racial variation in chronic conditions and sociodemographic characteristics among high-utilizing patients in the Veterans Affairs Healthcare System (VA).We identified the 5 % most costly Veterans who used inpatient or outpatient care at the VA during fiscal year 2010 (N = 237,691) based on costs of inpatient and outpatient care, pharmacy services, and VA-sponsored contract care. Patient costs and characteristics were abstracted from VA outpatient and inpatient data files. Racial differences in sociodemographic characteristics (age, sex, marital support, homelessness, and health insurance status) were assessed with chi-square tests. Racial differences in 32 chronic condition diagnoses were calculated as relative risk ratios.African-Americans represented 21 % of high-utilizing Veterans. African-Americans had higher rates of homelessness (26 vs. 10 %, p < 0.001) and lower rates of supplemental health insurance (44 vs. 58 %, p < 0.001). The mean number of chronic conditions was similar across race. However, there were racial differences in the prevalence of specific chronic conditions, including a higher prevalence of HIV/AIDS (95 % confidence interval (CI) 4.86, 5.50) and schizophrenia (95 % CI 1.94, 2.07) and a lower prevalence of ischemic heart disease (95 % CI 0.57, 0.59) and bipolar disorder (95 % CI 0.78, 0.85) among African-American high-utilizing Veterans.Racial disparities among high-utilizing Veterans may differ from those found in the general population. Interventions should devote attention to social, environmental, and mental health issues in order to reduce racial disparities in this vulnerable population.

• The Effect of Medical Comorbidities on Male and Female Veterans' Use of Psychotherapy for PTSD. Medical care Breland, J. Y., Greenbaum, M. A., Zulman, D. M., Rosen, C. S. 2015; 53 (4): S120-7

  Abstract

  Posttraumatic stress disorder (PTSD) is associated with an increased risk for medical comorbidities that may prevent participation in psychotherapy. The present study investigated whether medical comorbidities were associated with lower initiation rates and fewer psychotherapy visits for PTSD. Because women are more likely to initiate psychotherapy after traumatic events, we also assessed whether relationships were weaker among women.Veterans (N=482, 47% women) recently diagnosed with PTSD completed a survey assessing demographics, mood, functional status, and interest in treatment. Data on medical comorbidities, psychotherapy visits, antidepressant prescriptions, and service connection were assessed longitudinally through administrative files. Logistic and negative binomial regressions assessed associations between number of medical comorbidities in the 2 years before the survey and the initiation and number of psychotherapy visits for PTSD in the year after the survey. All analyses were stratified by sex and controlled for survey and administrative variables.The relationship between medical comorbidities and number of psychotherapy visits was stronger among women than among men. A greater number of medical comorbidities was associated with significantly fewer psychotherapy visits in the total sample [incidence rate ratio: 0.91; 95% confidence interval (CI): 0.83, 1.00] and among women (incidence rate ratio: 0.87; 95% CI: 0.77, 0.99), but not among men (95% CI: 0.75, 1.01). Medical comorbidities were not associated with the initiation of psychotherapy among men or women.Addressing medical comorbidities may help individuals remain in psychotherapy for PTSD. Medical comorbidities may play a larger role in the number of psychotherapy visits among women than men.

• Using a Clinical Knowledge Base to Assess Comorbidity Interrelatedness Among Patients with Multiple Chronic Conditions. AMIA ... Annual Symposium proceedings / AMIA Symposium. AMIA Symposium Zulman, D. M., Martins, S. B., Liu, Y., Tu, S. W., Hoffman, B. B., Asch, S. M., Goldstein, M. K. 2015; 2015: 1381-1389

  Abstract

  Decision support tools increasingly integrate clinical knowledge such as medication indications and contraindications with electronic health record (EHR) data to support clinical care and patient safety. The availability of this encoded information and patient data provides an opportunity to develop measures of clinical decision complexity that may be of value for quality improvement and research efforts. We investigated the feasibility of using encoded clinical knowledge and EHR data to develop a measure of comorbidity interrelatedness (the degree to which patients' co-occurring conditions interact to generate clinical complexity). Using a common clinical scenario-decisions about blood pressure medications in patients with hypertension-we quantified comorbidity interrelatedness by calculating the number of indications and contraindications to blood pressure medications that are generated by patients' comorbidities (e.g., diabetes, gout, depression). We examined properties of comorbidity interrelatedness using data from a decision support system for hypertension in the Veterans Affairs Health Care System.

• Automating Identification of Multiple Chronic Conditions in Clinical Practice Guidelines. AMIA Joint Summits on Translational Science proceedings AMIA Summit on Translational Science Leung, T. I., Jalal, H., Zulman, D. M., Dumontier, M., Owens, D. K., Musen, M. A., Goldstein, M. K. 2015; 2015: 456-460

  Abstract

  Many clinical practice guidelines (CPGs) are intended to provide evidence-based guidance to clinicians on a single disease, and are frequently considered inadequate when caring for patients with multiple chronic conditions (MCC), or two or more chronic conditions. It is unclear to what degree disease-specific CPGs provide guidance about MCC. In this study, we develop a method for extracting knowledge from single-disease chronic condition CPGs to determine how frequently they mention commonly co-occurring chronic diseases. We focus on 15 highly prevalent chronic conditions. We use publicly available resources, including a repository of guideline summaries from the National Guideline Clearinghouse to build a text corpus, a data dictionary of ICD-9 codes from the Medicare Chronic Conditions Data Warehouse (CCW) to construct an initial list of disease terms, and disease synonyms from the National Center for Biomedical Ontology to enhance the list of disease terms. First, for each disease guideline, we determined the frequency of comorbid condition mentions (a disease-comorbidity pair) by exactly matching disease synonyms in the text corpus. Then, we developed an annotated reference standard using a sample subset of guidelines. We used this reference standard to evaluate our approach. Then, we compared the co-prevalence of common pairs of chronic conditions from Medicare CCW data to the frequency of disease-comorbidity pairs in CPGs. Our results show that some disease-comorbidity pairs occur more frequently in CPGs than others. Sixty-one (29.0%) of 210 possible disease-comorbidity pairs occurred zero times; for example, no guideline on chronic kidney disease mentioned depression, while heart failure guidelines mentioned ischemic heart disease the most frequently. Our method adequately identifies comorbid chronic conditions in CPG recommendations with precision 0.82, recall 0.75, and F-measure 0.78. Our work identifies knowledge currently embedded in the free text of clinical practice guideline recommendations and provides an initial view of the extent to which CPGs mention common comorbid conditions. Knowledge extracted from CPG text in this way may be useful to inform gaps in guideline recommendations regarding MCC and therefore identify potential opportunities for guideline improvement.

  We employed a partnered research healthcare delivery redesign process to improve care for high-need, high-cost (HNHC) patients within the Veterans Affairs (VA) healthcare system.Health services researchers partnered with VA national and Palo Alto facility leadership and clinicians to: 1) analyze characteristics and utilization patterns of HNHC patients, 2) synthesize evidence about intensive management programs for HNHC patients, 3) conduct needs-assessment interviews with HNHC patients (n = 17) across medical, access, social, and mental health domains, 4) survey providers (n = 8) about care challenges for HNHC patients, and 5) design, implement, and evaluate a pilot Intensive Management Patient-Aligned Care Team (ImPACT) for a random sample of 150 patients.HNHC patients accounted for over half (52 %) of VA facility patient costs. Most (94 %) had three or more chronic conditions, and 60 % had a mental health diagnosis. Formative data analyses and qualitative assessments revealed a need for intensive case management, care coordination, transitions navigation, and social support and services. The ImPACT multidisciplinary team developed care processes to meet these needs, including direct access to team members (including after-hours), chronic disease management protocols, case management, and rapid interventions in response to health changes or acute service use. Two-thirds of invited patients (n = 101) enrolled in ImPACT, 87 % of whom remained actively engaged at 9 months. ImPACT is now serving as a model for a national VA intensive management demonstration project.Partnered research that incorporated population data analysis, evidence synthesis, and stakeholder needs assessments led to the successful redesign and implementation of services for HNHC patients. The rigorous design process and evaluation facilitated dissemination of the intervention within the VA healthcare system.Employing partnered research to redesign care for high-need, high-cost patients may expedite development and dissemination of high-value, cost-saving interventions.

• Blue Button use by patients to access and share health record information using the Department of Veterans Affairs' online patient portal. Journal of the American Medical Informatics Association Turvey, C., Klein, D., Fix, G., Hogan, T. P., Woods, S., Simon, S. R., Charlton, M., Vaughan-Sarrazin, M., Zulman, D. M., Dindo, L., Wakefield, B., Graham, G., Nazi, K. 2014; 21 (4): 657-663

  Abstract

  The Blue Button feature of online patient portals promotes patient engagement by allowing patients to easily download their personal health information. This study examines the adoption and use of the Blue Button feature in the Department of Veterans Affairs' (VA) personal health record portal, My HealtheVet.An online survey presented to a 4% random sample of My HealtheVet users between March and May 2012. Questions were designed to determine characteristics associated with Blue Button use, perceived value of use, and how Veterans with non-VA providers use the Blue Button to share information with their non-VA providers.Of the survey participants (N=18 398), 33% were current Blue Button users. The most highly endorsed benefit was that it helped patients understand their health history better because all the information was in one place (73%). Twenty-one percent of Blue Button users with a non-VA provider shared their VA health information, and 87% reported that the non-VA provider found the information somewhat or very helpful. Veterans' self-rated computer ability was the strongest factor contributing to both Blue Button use and to sharing information with non-VA providers. When comparing Blue Button users and non-users, barriers to adoption were low awareness of the feature and difficulty using the Blue Button.This study contributes to the understanding of early Blue Button adoption and use of this feature for patient-initiated sharing of health information. Educational efforts are needed to raise awareness of the Blue Button and to address usability issues that hinder adoption.

• Costs Associated With Multimorbidity Among VA Patients. Medical care Yoon, J., Zulman, D., Scott, J. Y., Maciejewski, M. L. 2014; 52: S31-6

  Abstract

  Multimorbidity (the presence of multiple chronic conditions) is associated with high levels of healthcare utilization and associated costs. We investigated the association between number of chronic conditions and costs of care for nonelderly and elderly Veterans Affairs (VA) patients, and estimated mean VA healthcare costs for the most prevalent and most costly combinations of 3 conditions (triads).We identified a cohort of 5,233,994 patients who received care within the VA system in fiscal year 2010. We estimated the costs of VA care for each patient using established methods and aggregated costs for inpatient care, outpatient care, prescription drugs, and contract care. Using ICD-9 diagnosis fields from all inpatient and outpatient records, we determined the prevalence of 28 chronic conditions and all condition triads. We then compared the condition-cost gradient, most prevalent triads, and most costly triads among nonelderly (below 65 y) and elderly (65 y and above) patients.Almost one third of nonelderly and slightly more than a third of elderly VA patients had ≥3 conditions, but these patients accounted for 65% and 67% of total VA healthcare costs, respectively. The most common triad of chronic conditions for both nonelderly and elderly patients was diabetes, hyperlipidemia, and hypertension (24% and 29%, respectively). Conditions that were present in the most costly triads included spinal cord injury, heart failure, renal failure, ischemic heart disease, peripheral vascular disease, stroke, and depression. Although patients with the most costly triads had average costs that were 3 times higher than average costs among patients with ≥3 conditions, the prevalence of these costly triads was extremely low (0.1%-0.4%).Patients with multiple chronic conditions account for a disproportionate share of VA healthcare expenditures. Interventions that aim to optimize care and contain costs for multimorbid patients need to incorporate strategies specific to the most prevalent and the most costly combinations of conditions.

• Implementation and evaluation of an incentivized Internet-mediated walking program for obese adults. Translational behavioral medicine Zulman, D. M., Damschroder, L. J., Smith, R. G., Resnick, P. J., Sen, A., Krupka, E. L., Richardson, C. R. 2013; 3 (4): 357-369

  Abstract

  In response to rising health care costs associated with obesity rates, some health care insurers are adopting incentivized technology-enhanced wellness programs. The purpose of this study is to evaluate the large-scale implementation of an incentivized Internet-mediated walking program for obese adults and to examine program acceptance, adherence, and impact. A mixed-methods evaluation was conducted to investigate program implementation, acceptance, and adherence rates, and physical activity rates among program participants. Program implementation was shaped by national and state policies, data security concerns, and challenges related to incentivizing participation. Among 15,397 eligible individuals, 6,548 (43 %) elected to participate in the walking program, achieving an average of 6,523 steps/day (SD 2,610 steps). Participants who uploaded step counts for 75 % of days for a full year (n = 2,885) achieved an average of 7,500 steps (SD 3,093). Acceptance and participation rates in this incentivized Internet-mediated walking program suggest that such interventions hold promise for engaging obese adults in physical activity.

• Research Priorities in Geriatric Palliative Care: Multimorbidity JOURNAL OF PALLIATIVE MEDICINE Ritchie, C. S., Zulman, D. M. 2013; 16 (8): 843-847

  Abstract

  With global aging and scientific advances extending survival, the number of adults experiencing multiple chronic conditions has grown substantially and is projected to increase by another third between 2000 and 2030. Among the many challenges posed by multimorbidity, some of the most pressing include how to characterize and measure comorbid conditions, understand symptoms and illness burden, and provide person-centered care in the context of competing health care priorities and increasing complexity. In this white paper emanating from a National Institute on Aging supported conference to discuss research gaps at the geriatrics-palliative care interface, the authors review common definitions of multimorbidity; describe the association between multimorbidity and quality of life, functional status, quality of care, and health care utilization; note content and methodological gaps in multimorbidity evidence; and make recommendations regarding research priorities in this area of expanding public health impact.

• Facilitating out-of-home caregiving through health information technology: survey of informal caregivers' current practices, interests, and perceived barriers. Journal of medical Internet research Zulman, D. M., Piette, J. D., Jenchura, E. C., Asch, S. M., Rosland, A. 2013; 15 (7)

  Abstract

  Many patients with chronic conditions are supported by out-of-home informal caregivers-family members, friends, and other individuals who provide care and support without pay-who, if armed with effective consumer health information technology, could inexpensively facilitate their care.We sought to understand caregivers' use of, interest in, and perceived barriers to health information technology for out-of-home caregiving.We conducted 2 sequential Web-based surveys with a national sample of individuals who provide out-of-home caregiving to an adult family member or friend with a chronic illness. We queried respondents about their use of health information technology for out-of-home caregiving and used multivariable regression to investigate caregiver and care-recipient characteristics associated with caregivers' technology use for caregiving.Among 316 out-of-home caregiver respondents, 34.5% (109/316) reported using health information technology for caregiving activities. The likelihood of a caregiver using technology increased significantly with intensity of caregiving (as measured by number of out-of-home caregiving activities). Compared with very low intensity caregivers, the adjusted odds ratio (OR) of technology use was 1.88 (95% CI 1.01-3.50) for low intensity caregivers, 2.39 (95% CI 1.11-5.15) for moderate intensity caregivers, and 3.70 (95% CI 1.62-8.45) for high intensity caregivers. Over 70% (149/207) of technology nonusers reported interest in using technology in the future to support caregiving. The most commonly cited barriers to technology use for caregiving were health system privacy rules that restrict access to care-recipients' health information and lack of familiarity with programs or websites that facilitate out-of-home caregiving.Health information technology use for out-of-home caregiving is common, especially among individuals who provide more intense caregiving. Health care systems can address the mismatch between caregivers' interest in and use of technology by modifying privacy policies that impede information exchange.

• Cardiac Risk Is Not Associated With Hypertension Treatment Intensification AMERICAN JOURNAL OF MANAGED CARE Sussman, J. B., Zulman, D. M., Hayward, R., Hofer, T. P., Kerr, E. A. 2012; 18 (8): 414-420

  Abstract

  Considering cardiovascular (CV) risk could make clinical care more efficient and individualized, but most practice guidelines focus on single risk factors. We sought to determine if hypertension treatment intensification (TI) is more likely in patients with elevated CV risk.Prospective cohort study of 856 US veterans with diabetes and elevated blood pressure (BP).We used multilevel logistic regression to compare TI across 3 CV risk groups: those with history of heart disease, a high-risk primary prevention group (10-year event risk >20% but no history of heart disease), and those with low/ medium CV risk (10-year event risk <20%).There were no significant differences in TI rates across risk groups, with adjusted odds ratios (ORs) of 1.19 (95% confidence interval 0.77-1.84) and 1.18 (0.76-1.83) for high-risk patients and those with a history of CVD, respectively, compared with those of low/medium risk. Several individual risk factors were associated with higher rates of TI: systolic BP, mean BP in the prior year, and higher glycated hemoglobin. Self-reported home BP <140/90 mm Hg was associated with lower rates of TI. Incorporating CV risk into TI decision algorithms could prevent an estimated 38% more cardiac events without increasing the number of treated patients.While an individual's BP alters clinical decisions about TI, overall CV risk does not appear to play a role in clinical decision making. Adoption of TI decision algorithms that incorporate CV risk could substantially enhance the efficiency and clinical utility of CV preventive care.

• The influence of diabetes psychosocial attributes and self-management practices on change in diabetes status PATIENT EDUCATION AND COUNSELING Zulman, D. M., Rosland, A., Choi, H., Langa, K. M., Heisler, M. 2012; 87 (1): 74-80

  Abstract

  To examine the influence of diabetes psychosocial attributes and self-management on glycemic control and diabetes status change.Using data from the Health and Retirement Study, a nationally representative longitudinal study of U.S. adults >51 years, we examined cross-sectional relationships among diabetes psychosocial attributes (self-efficacy, risk awareness, care understanding, prioritization of diabetes, and emotional distress), self-management ratings, and glycemic control. We then explored whether self-management ratings and psychosocial attributes in 2003 predicted change in diabetes status in 2004.In multivariate analyses (N=1834), all diabetes psychosocial attributes were associated with self-management ratings, with self-efficacy and diabetes distress having the strongest relationships (adj coeff=8.1, p<0.01 and -4.1, p<0.01, respectively). Lower self-management ratings in 2003 were associated cross-sectionally with higher hemoglobin A1C (adj coeff=0.16, p<0.01), and with perceived worsening diabetes status in 2004 (adj OR=1.36, p<0.05), with much of this latter relationship explained by diabetes distress.Psychosocial attributes, most notably diabetes-related emotional distress, contribute to difficulty with diabetes self-management, poor glycemic control, and worsening diabetes status over time.Self-management and adherence interventions should target psychosocial attributes such as disease-related emotional distress.

• Transfer of Information from Personal Health Records: A Survey of Veterans Using My HealtheVet TELEMEDICINE AND E-HEALTH Turvey, C. L., Zulman, D. M., Nazi, K. M., Wakefield, B. J., Woods, S. S., Hogan, T. P., Weaver, F. M., McInnes, K. 2012; 18 (2): 109-114

  Abstract

  Personal health records provide patients with ownership of their health information and allow them to share information with multiple healthcare providers. However, the usefulness of these records relies on patients understanding and using their records appropriately. My HealtheVet is a Web-based patient portal containing a personal health record administered by the Veterans Health Administration. The goal of this study was to explore veterans' interest and use of My HealtheVet to transfer and share information as well as to identify opportunities to increase veteran use of the My HealtheVet functions.Two waves of data were collected in 2010 through an American Customer Satisfaction Index Web-based survey. A random sample of veterans using My HealtheVet was invited to participate in the survey conducted on the My HealtheVet portal through a Web-based pop-up browser window.Wave One results (n=25,898) found that 41% of veterans reported printing information, 21% reported saving information electronically, and only 4% ever sent information from My HealtheVet to another person. In Wave Two (n=18,471), 30% reported self-entering medication information, with 18% sharing this information with their Veterans Affairs (VA) provider and 9.6% sharing with their non-VA provider.Although veterans are transferring important medical information from their personal health records, increased education and awareness are needed to increase use. Personal health records have the potential to improve continuity of care. However, more research is needed on both the barriers to adoption as well as the actual impact on patient health outcomes and well-being.

• Adapting an in-person patient-caregiver communication intervention to a tailored web-based format PSYCHO-ONCOLOGY Zulman, D. M., Schafenacker, A., Barr, K. L., Moore, I. T., Fisher, J., McCurdy, K., Derry, H. A., Saunders, E. W., An, L. C., Northouse, L. 2012; 21 (3): 336-341

  Abstract

  Interventions that target cancer patients and their caregivers have been shown to improve patient-caregiver communication, support, and emotional well-being.To adapt an in-person communication intervention for cancer patients and caregivers to a web-based format, and to examine the usability and acceptability of the web-based program among representative users.A tailored, interactive web-based communication program for cancer patients and their family caregivers was developed based on an existing in-person, nurse-delivered intervention. The development process involved: (1) building a multidisciplinary team of content and web design experts, (2) combining key components of the in-person intervention with the unique tailoring and interactive features of a web-based platform, and (3) conducting focus groups and usability testing to obtain feedback from representative program users at multiple time points. Results: Four focus groups with 2-3 patient-caregiver pairs per group (n = 22 total participants) and two iterations of usability testing with four patient-caregiver pairs per session (n = 16 total participants) were conducted. Response to the program's structure, design, and content was favorable, even among users who were older or had limited computer and Internet experience. The program received high ratings for ease of use and overall usability (mean System Usability Score of 89.5 out of 100).Many elements of a nurse-delivered patient-caregiver intervention can be successfully adapted to a web-based format. A multidisciplinary design team and an iterative evaluation process with representative users were instrumental in the development of a usable and well-received web-based program.

• Trust in the Internet as a Health Resource Among Older Adults: Analysis of Data from a Nationally Representative Survey JOURNAL OF MEDICAL INTERNET RESEARCH Zulman, D. M., Kirch, M., Zheng, K., An, L. C. 2011; 13 (1): 202-211

  Abstract

  Distrust in the Internet as a source of health information remains common among older adults. The influence of this distrust on Internet use for health-related purposes, however, is unclear.The objective of our study was to explore how older adults' trust in the Internet influences their online health-related activities, and to identify potential targets for improving health-related Internet resources for older adults.Data were obtained from a nationally representative, random digit-dial telephone survey of 1450 adults 50 years of age and older in the United States. A model was developed to conceptualize the hypothesized relationships among individual characteristics, distrust, and avoidance of the Internet as a health resource. Multivariate logistic regression analyses were conducted to examine the association between trust in online health information and use of the Internet for health-related purposes. Additional multivariate logistic regression analyses were conducted to identify the key characteristics associated with trust in online health information, adding sequentially the variables hypothesized to account for distrust among older adults: sociodemographic and health characteristics, inexperience and technical difficulties with the Internet, negative feelings toward the Internet, and lack of awareness about the sources providing the health information found online.The mean (SD) age of the study population was 63.7 (10.6) years. Of the 823 (56.8%) Internet users, 628 (76.3%) reported using the Internet as a health resource. Trust in the Internet as a source of health information was associated with using the Internet for a number of health activities, including searching for information about a specific health condition (adjusted OR 4.43, P < .001), purchasing prescription drugs (adjusted OR 2.61, P = .03), and talking with a health care provider about information found online (adjusted OR 2.54, P = .002). Older adults (age ≥ 65 years) were less likely to trust the Internet as a source of health information (OR 0.63, P = .04), even after adjusting for other sociodemographic characteristics and health and function. This age effect was only slightly attenuated (adjusted OR 0.69, P = .13) after adjusting for inexperience and technical difficulties with the Internet, but it disappeared entirely (adjusted OR 0.96, P = .91) after adjusting for other hypothesized contributors to distrust (including finding the Internet confusing because it provides "too much information," and lacking awareness about the source providing health information found online).Website design features that clearly identify the source and credibility of information and minimize confusion may build trust among older adults and offer an opportunity to increase the utility of the Internet as a health resource for this population.

• Patient-Provider Concordance in the Prioritization of Health Conditions Among Hypertensive Diabetes Patients 32nd Annual National Meeting of the Society-for-General-Internal-Medicine Zulman, D. M., Kerr, E. A., Hofer, T. P., Heisler, M., Zikmund-Fisher, B. J. SPRINGER. 2010: 408–14

  Abstract

  Many patients with diabetes have multiple other chronic conditions, but little is known about whether these patients and their primary care providers agree on the relative importance that they assign these comorbidities.To understand patterns of patient-provider concordance in the prioritization of health conditions in patients with multimorbidity.Prospective cohort study of 92 primary care providers and 1,169 of their diabetic patients with elevated clinic triage blood pressure (> or = 140/90) at nine Midwest VA facilities.We constructed a patient-provider concordance score based on responses to surveys in which patients were asked to rank their most important health concerns and their providers were asked to rank the most important conditions likely to affect that patient's health outcomes. We then calculated the change in predicted probability of concordance when the patient reported having poor health status, pain or depression, or competing demands (issues that were more pressing than his health), controlling for both patient and provider characteristics.For 714 pairs (72%), providers ranked the patient's most important concern in their list of three conditions. Both patients and providers ranked diabetes and hypertension most frequently; however, providers were more likely to rank hypertension as most important (38% vs. 18%). Patients were more likely than providers to prioritize symptomatic conditions such as pain, depression, and breathing problems. The predicted probability of patient-provider concordance decreased when a patient reported having poor health status (55% vs. 64%, p < 0.01) or non-health competing demands (46% vs. 62%, p < 0.01).Patients and their primary care providers often agreed on the most important health conditions affecting patients with multimorbidity, but this concordance was lower for patients with poor health status or non-health competing demands. Interventions that increase provider awareness about symptomatic concerns and competing demands may improve chronic disease management in these vulnerable patients.

• Optimizing Statin Treatment for Primary Prevention of Coronary Artery Disease ANNALS OF INTERNAL MEDICINE Hayward, R. A., Krumholz, H. M., Zulman, D. M., Timbie, J. W., Vijan, S. 2010; 152 (2): 69-?

  Abstract

  Although treating to lipid targets ("treat to target") is widely recommended for coronary artery disease (CAD) prevention, some have advocated administering fixed doses of statins based on a person's estimated net benefit ("tailored treatment").To examine how a tailored treatment approach to statin therapy compares with a treat-to-target approach.Simulated model of population-level effects of treat-to-target and tailored treatment approaches to statin therapy.Statin trials from 1994 to 2009 and nationally representative CAD risk factor data.U.S. persons aged 30 to 75 years with no history of myocardial infarction.Lifetime effects of 5 years of treatment.Societal and patient.Tailored treatment based on a person's 5-year CAD risk (simvastatin, 40 mg, for 5% to 15% CAD risk and atorvastatin, 40 mg, for CAD risk >15%) versus treat-to-target approaches that escalate statin dose per National Cholesterol Education Program [NCEP] III guidelines (including an intensive approach that advances treatment whenever intensification is optional by NCEP III criteria).Quality-adjusted life-years (QALYs).Compared with the standard NCEP III approach, the intensive NCEP III approach treated 15 million more persons and saved 570,000 more QALYs over 5 years. The tailored strategy treated a similar number of persons, as did the intensive NCEP III approach, but saved 500,000 more QALYs and treated fewer persons with high-dose statins.No circumstances were found in which a treat-to-target approach was preferable to tailored treatment.Model assumptions were based on available clinical data, which included few persons 75 years or older.A tailored treatment strategy prevents more CAD events while treating fewer persons with high-dose statins than low-density lipoprotein cholesterol-based target approaches. Results were robust, even with assumptions favoring a treat-to-target approach.Department of Veteran Affairs Health Services Research & Development Service's Quality Enhancement Research Initiative.

• The Relative Merits of Population-Based and Targeted Prevention Strategies MILBANK QUARTERLY Zulman, D. M., Vijan, S., Omenn, G. S., Hayward, R. A. 2008; 86 (4): 557-580

  Abstract

  Preventive medicine has historically favored reducing a risk factor by a small amount in the entire population rather than by a large amount in high-risk individuals. The use of multivariable risk prediction tools, however, may affect the relative merits of this strategy.This study uses risk factor data from the National Health and Nutrition Examination Survey III to simulate a population of more than 100 million Americans aged thirty or older with no history of CV disease. Three strategies that could affect CV events, CV mortality, and quality-adjusted life years were examined: (1) a population-based strategy that treats all individuals with a low- or moderate-intensity intervention (in which the low-intensity intervention represents a public health campaign with no demonstrable adverse effects), (2) a targeted strategy that treats individuals in the top 25 percent based on a single risk factor (LDL), and (3) a risk-targeted strategy that treats individuals in the top 25 percent based on overall CV risk (as predicted by a multivariable prediction tool). The efficiency of each strategy was compared while varying the intervention's intensity and associated adverse effects, and the accuracy of the risk prediction tool.The LDL-targeted strategy and the low-intensity population-based strategy were comparable for CV events prevented over five years (0.79 million and 0.75 million, respectively), as were the risk-targeted strategy and moderate-intensity population-based strategy (1.56 million and 1.87 million, respectively). The risk-targeted strategy, however, was more efficient than the moderate-intensity population-based strategy (number needed to treat [NNT] 19 vs. 62). Incorporating a small degree of treatment-related adverse effects greatly magnified the relative advantages of the risk-targeted approach over other strategies. Reducing the accuracy of the prediction tool only modestly decreased this greater efficiency.A population-based prevention strategy can be an excellent option if an intervention has almost no adverse effects. But if the intervention has even a small degree of disutility, a targeted approach using multivariable risk prediction can prevent more morbidity and mortality while treating many fewer people.

  We report on a man seeking care at the UCLA mobile clinic, illustrating and then discussing the challenges of caring for people who are homeless (especially mental illness and potential distrust of providers). Student-run free clinics can be beneficial but further research must examine how well such clinics meet homeless patients' needs.

• State Long Term Care Ombudsman Programs: Factors associated with perceived effectiveness GERONTOLOGIST Estes, C. L., Zulman, D. M., Goldberg, S. C., Ogawa, D. D. 2004; 44 (1): 104-115

  Abstract

  This article reports findings from a nationwide study on factors associated with the perceived effectiveness of state Long Term Care Ombudsman Programs (LTCOPs).Researchers conducted telephone interviews with ombudsmen from the 50 state programs as well as from Washington, DC, and Puerto Rico. Data from the National Ombudsman Reporting System were incorporated into the study, and statistical tests analyze associations between self-rated program effectiveness and adequacy of resources, organizational placement-autonomy, interorganizational relationships, and other variables.Several factors limit the perceived effectiveness of state LTCOPs, including insufficient funding and insufficient LTCOP autonomy caused by organizational placement. Despite these problem areas, state ombudsmen report that their programs meet statutorily mandated requirements with varying degrees of effectiveness. Findings show significant positive associations between program funding and paid and volunteer staff levels and between the ratio of long-term care beds per ombudsman and the percentage of nursing facilities visited. Sufficient funding is positively associated with perceived effectiveness of work with nursing facilities.Sufficient resources, sufficient organizational autonomy, and a supportive political and social environment are key elements in achieving varying types of perceived effectiveness in the state LTCOPs. Research is needed to extend this work to local ombudsman programs and to compare self-rated effectiveness with other outcome measures.
