  • Impact of participation in the California Healthcare-Associated Infection Prevention Initiative on adoption and implementation of evidence-based practices for patient safety and health care-associated infection rates in a cohort of acute care general hospitals AMERICAN JOURNAL OF INFECTION CONTROL Halpin, H. A., McMenamin, S. B., Simon, L. P., Jacobsen, D., Vanneman, M., Shortell, S., Milstein, A. 2013; 41 (4): 307-311

    Abstract

    In 2008, hospitals were selected to participate in the California Healthcare-Associated Infection Prevention Initiative (CHAIPI). This research evaluates the impact of CHAIPI on hospital adoption and implementation of evidence-based patient safety practices and reduction of health care-associated infection (HAI) rates.Statewide computer-assisted telephone surveys of California's general acute care hospitals were conducted in 2008 and 2010 (response rates, 80% and 76%, respectively). Difference-in-difference analyses were used to compare changes in process and HAI rate outcomes in CHAIPI hospitals (n = 34) and non-CHAIPI hospitals (n = 149) that responded to both waves of the survey.Compared with non-CHAIPI hospitals, CHAIPI hospitals demonstrated greater improvements between 2008 and 2010 in adoption (P = .021) and implementation (P = .012) of written evidence-based practices for overall patient safety and prevention of HAIs and in assessing their compliance (P = .033) with these practices. However, there were no significant differences in the changes in HAI rates between CHAIPI and non-CHAIPI hospitals over this time period.Participation in the CHAIPI collaborative was associated with significant improvements in evidence-based patient safety practices in hospitals. However, determining how evidence-based practices translate into changes in HAI rates may take more time. Our results suggest that all hospitals be offered the opportunity to participate in an active learning collaborative to improve patient safety.

  • Hospital adoption of automated surveillance technology and the implementation of infection prevention and control programs AMERICAN JOURNAL OF INFECTION CONTROL Halpin, H., Shortell, S. M., Milstein, A., Vanneman, M. 2011; 39 (4): 270-276

    Abstract

    This research analyzes the relationship between hospital use of automated surveillance technology (AST) for identification and control of hospital-acquired infections (HAI) and implementation of evidence-based infection control practices. Our hypothesis is that hospitals that use AST have made more progress implementing infection control practices than hospitals that rely on manual surveillance.A survey of all acute general care hospitals in California was conducted from October 2008 through January 2009. A structured computer-assisted telephone interview was conducted with the quality director of each hospital. The final sample includes 241 general acute care hospitals (response rate, 83%).Approximately one third (32.4%) of California's hospitals use AST for monitoring HAI. Adoption of AST is statistically significant and positively associated with the depth of implementation of evidence-based practices for methicillin-resistant Staphylococcus aureus and ventilator-associated pneumonia and adoption of contact precautions and surgical care infection practices. Use of AST is also statistically significantly associated with the breadth of hospital implementation of evidence-based practices across all 5 targeted HAI.Our findings suggest that hospitals using AST can achieve greater depth and breadth in implementing evidenced-based infection control practices.

  • Mandatory Public Reporting Of Hospital-Acquired Infection Rates: A Report From California HEALTH AFFAIRS Halpin, H. A., Milstein, A., Shortell, S. M., Vanneman, M., Rosenberg, J. 2011; 30 (4): 723-729

    Abstract

    One way to motivate hospitals to improve patient safety is to publicly report their rates of hospital-acquired infections, as California is starting to do this year. We conducted a baseline study of California's acute care hospitals just before mandatory reporting of hospital-acquired infection rates to the state began, in 2008. We found variability in many areas: For example, 70.1 percent of hospitals said that they were fully implementing evidence-based guidelines to fight infection by methicillin-resistant Staphylococcus aureus, but 22.8 percent of hospitals had not adopted any. Our analysis showed that rural hospitals, many of which lack resources to implement needed procedures, faced the greatest challenges in reporting and improving infection rates. Our findings should be of interest to Medicare policy makers who will implement the hospital-acquired infection performance measures in the Affordable Care Act, and to leaders in the thirty-eight states that have enacted legislation requiring reports of hospital-acquired infection rates. California's baseline data also present a unique opportunity to assess the impact of mandatory and public reporting laws.

  • Patient safety climate: variation in perceptions by infection preventionists and quality directors. Interdisciplinary perspectives on infectious diseases Nelson, S., Stone, P. W., Jordan, S., Pogorzelska, M., Halpin, H., Vanneman, M., Larson, E. 2011; 2011: 357121-?

    Abstract

    Background. Healthcare-associated infections (HAIs) are an important patient safety issue, and safety climate is an important organizational factor. This study explores perceptions of infection preventionists (IPs) and quality directors (QDs) regarding two safety microclimates, Senior Management Engagement (SME) and Leadership on Patient Safety (LOPS), across California hospitals. Methods. This was an analysis of two cross-sectional surveys. We conducted Wilcoxon signed-rank test, univariate analyses, and a multivariate ordinary least square regression. Results. There were 322 eligible hospitals; 149 hospitals (46.3%) responded to both surveys. The IP response rate was 59%, and the QD response rate was 79.5%. We found IPs perceived SME more positively than did QDs (21.4 vs. 20.4, P < 0.01). No setting characteristics predicted variation in perceptions. Presence of an independent budget predicted more positive perceptions of microclimates across personnel types (P < 0.01). Conclusions. Differences in perceptions continue to exist between essential leaders in acute health care settings which could have critical effects on outcomes such as HAIs. Having an independent budget for the infection prevention and control department may enhance the overall safety climate and in turn patient care.
