  • Response to strict and liberalized specific carbohydrate diet in pediatric Crohn's disease. World journal of gastroenterology Burgis, J. C., Nguyen, K., Park, K. T., Cox, K. 2016; 22 (6): 2111-7

    Abstract

    To investigate the specific carbohydrate diet (SCD) as nutritional therapy for maintenance of remission in pediatric Crohn's disease (CD).Retrospective chart review was conducted in 11 pediatric patients with CD who initiated the SCD as therapy at time of diagnosis or flare. Two groups defined as SCD simple (diet alone, antibiotics or 5-ASA) or SCD with immunomodulators (corticosteroids and/or stable thiopurine dosing) were followed for one year and compared on disease characteristics, laboratory values and anthropometrics.The mean age at start of the SCD was 11.8 3.0 years (range 6.6-17.6 years) with five patients starting the SCD within 5 wk of diagnosis. Three patients maintained a strict SCD diet for the study period and the mean time for liberalization was 7.7 4.0 mo (range 1-12) for the remaining patients. In both groups, hematocrit, albumin and ESR values improved while on strict SCD and appeared stable after liberalization (P-value 0.006, 0.002, 0.002 respectively). The majority of children gained in weight and height percentile while on strict SCD, with small loss in weight percentile documented with liberalization.Disease control may be attainable with the SCD in pediatric CD. Further studies are needed to assess adherence, impact on mucosal healing and growth.

  • Out-of-pocket Cost Burden in Pediatric Inflammatory Bowel Disease: A Cross-sectional Cohort Analysis INFLAMMATORY BOWEL DISEASES Sin, A. T., Damman, J. L., Ziring, D. A., Gleghorn, E. E., Garcia-Careaga, M. G., Gugig, R. R., Hunter, A. K., Burgis, J. C., Bass, D. M., Park, K. T. 2015; 21 (6): 1368-1377

    Abstract

    Pediatric inflammatory bowel disease (IBD), consisting of Crohn's disease (CD) and ulcerative colitis (UC), can result in significant morbidity requiring frequent health care utilization. Although it is known that the overall financial impact of pediatric IBD is significant, the direct out-of-pocket (OOP) cost burden on the parents of children with IBD has not been explored. We hypothesized that affected children with a more relapsing disease course and families in lower income strata, ineligible for need-based assistance programs, disparately absorb ongoing financial stress.We completed a cross-sectional analysis among parents of children with IBD residing in California using an online HIPAA-secure Qualtrics survey. Multicenter recruitment occurred between December 4, 2013 and September 18, 2014 at the point-of-care from site investigators, informational flyers distributed at regional CCFA conferences, and social media campaigns equally targeting Northern, Central, and Southern California. IBD-, patient-, and family-specific information were collected from the parents of pediatric patients with IBD patients younger than 18 years of age at time of study, carry a confirmed diagnosis of CD or UC, reside in and receive pediatric gastroenterology care in California, and do not have other chronic diseases requiring ongoing medical care.We collected 150 unique surveys from parents of children with IBD (67 CD; 83 UC). The median patient age was 14 years for both CD and UC, with an overall 3.7 years (SD 2.8 yr) difference between survey completion and time of IBD diagnosis. Annually, 63.6%, 28.6%, and 5.3% of families had an OOP cost burden >$500, >$1000, and >5000, respectively. Approximately one-third (36.0%) of patients had emergency department (ED) visits over the past year, with 59.2% of these patients spending >$500 on emergency department copays, including 11.1% who spent >$5000. Although 43.3% contributed <$500 on procedure and test costs, 20.0% spent >$2000 in the past year. Families with household income between $50,000 and $100,000 had a statistically significant probability (80.6%) of higher annual OOP costs than families with lower income <$50,000 (20.0%; P < 0.0001) or higher income >$100,000 (64.6%; P < 0.05). Multivariate analysis revealed that clinical variables associated with uncontrolled IBD states correlated to higher OOP cost burden. Annual OOP costs were more likely to be >$500 among patients who had increased spending on procedures and tests (odds ratio [OR], 5.63; 95% confidence interval [CI], 2.73-11.63), prednisone course required over the past year (OR, 3.19; 95% CI, 1.02-9.92), at least 1 emergency department visit for IBD symptoms (OR, 2.84; 95% CI, 1.33-6.06), at least 4 or more outpatient primary medical doctor visits for IBD symptoms (OR, 2.82; 95% CI, 1.40-5.68), and history of 4 or more lifetime hospitalizations for acute IBD care (OR, 2.60; 95% CI, 1.13-5.96).Previously undocumented, a high proportion of pediatric IBD families incur substantial OOP cost burden. Patients who are frequently in relapsing and uncontrolled IBD states require more acute care services and sustain higher OOP cost burden. Lower middle income parents of children with IBD ineligible for need-based assistance may be particularly at risk for financial stress from OOP costs related to ongoing medical care.

  • Resident perceptions of autonomy in a complex tertiary care environment improve when supervised by hospitalists. Hospital pediatrics Burgis, J. C., Lockspeiser, T. M., Stumpf, E. C., Wilson, S. D. 2012; 2 (4): 228-234

    Abstract

    Increasingly, academic hospitals have adopted hospitalist-based systems of inpatient pediatric care. Some studies comparing hospitalists with other attending physicians have suggested trainees are more satisfied with education from hospitalists. However, there are published concerns that the increased presence of hospitalists may reduce residents' autonomy. The objective of the current study was to evaluate pediatric residents' perceptions of their own autonomy after a broad ward restructuring to hospitalist-led teams.We analyzed data from standardized attending evaluations before and after a pediatric ward restructuring at an academic tertiary care hospital. Provision of most inpatient pediatric care changed from subspecialist-led teams to hospitalist-led teams. Numerical scores from evaluations before and after the restructuring were compared quantitatively. Comments from the evaluations were analyzed qualitatively to identify key themes.Before the restructuring, there were 65 evaluations of 5 hospitalists and 602 evaluations of 32 subspecialists. After the restructuring, there were 188 evaluations of 8 hospitalists. Hospitalists were rated significantly higher on all teaching attributes compared with all attending physicians before the restructuring. The attending role in promoting autonomy was mentioned infrequently and reflected residents' perceived lack of autonomy before the restructuring. The primary theme after the restructuring was autonomy, specifically emphasizing resident leadership and decision-making and the appropriate balance of resident autonomy and supervision.Although patient complexity was unchanged, a comparison of numerical ratings and resident comments before and after the restructuring indicates that hospitalists lead teams differently from subspecialists, with more emphasis on resident decision-making and autonomy.

  • Prevention and treatment strategies used for the community management of childhood fever in Kampala, Uganda AMERICAN JOURNAL OF TROPICAL MEDICINE AND HYGIENE Kemble, S. K., Davis, J. C., Nalugwa, T., Njama-Meya, D., Hopkins, H., Dorsey, G., Staedke, S. G. 2006; 74 (6): 999-1007

    Abstract

    To assess malaria-related prevention and treatment strategies in an urban parish of Kampala, Uganda, a questionnaire was administered to 339 randomly selected primary caregivers of children 1-10 years of age. Our study population was relatively stable and well educated, with better access to health services than many in Africa. Ownership of an insecticide-treated net (ITN) was reported by 11% of households and was predicted only by greater household wealth (highest quartile versus lowest quartile: odds ratio [OR] 21.8; 95% confidence interval [CI], 2.74-173). Among women, 5% reported use of an ITN and 11% used intermittent preventive therapy (IPT) during their last pregnancy. Use of appropriate IPT during pregnancy was predicted only by completion of secondary education or higher (OR, 2.87; 95% CI, 1.13-7.21). Children of 123 (36%) caregivers had experienced an episode of fever in the past 2 weeks. Of these, 22% received an anti-malarial that could be considered "adequate" (combination therapy or quinine). Only 1% of febrile children received adequate treatment at the correct dose within 24 hours of onset of fever. The only independent predictor of treatment with an adequate anti-malarial was accessing a clinic or hospital as the first source of care. In this urban area, use of appropriate malaria control measures occurs uncommonly.

  • Longitudinal study of urban malaria in a cohort of Ugandan children: description of study site, census and recruitment MALARIA JOURNAL Davis, J. C., Clark, T. D., Kemble, S. K., Talemwa, N., Njama-Meya, D., Staedke, S. G., Dorsey, G. 2006; 5

    Abstract

    Studies of malaria in well-defined cohorts offer important data about the epidemiology of this complex disease, but few have been done in urban African populations. To generate a sampling frame for a longitudinal study of malaria incidence and treatment in Kampala, Uganda, a census, mapping and survey project was conducted.All households in a geographically defined area were enumerated and mapped. Probability sampling was used to recruit a representative sample of children and collect baseline descriptive data for future longitudinal studies.16,172 residents living in 4931 households in a densely-populated community (18,824 persons/km2) were enumerated. A total of 582 households were approached with at least one child less than 10 years of age in order to recruit 601 children living in 322 households. At enrollment, 19% were parasitaemic, 24% were anaemic, 43% used bednets, and 6% used insecticide-treated nets. Low G6PD activity (OR = 0.33, P = 0.009) and bednet use (OR = 0.64, P = 0.045) were associated with a decreased risk of parasitaemia. Increasing age (OR = 0.62 for each year, P < 0.001) and bednet use (OR = 0.58, P = 0.02) were associated with a decreased risk of anaemiaDetailed surveys of target populations in urban Africa can provide valuable descriptive data and provide a sampling frame for recruitment of representative cohorts for longitudinal studies. Plans to use a multi-disciplinary approach to improve the understanding of the distribution and determinants of malaria incidence and response to therapy in this population are discussed.
