Assessment of patient safety culture in private and public hospitals in Peru

Background The Agency for Healthcare Research and Quality (AHRQ) Hospital Survey on Patient Safety Culture was designed to assess staff views on patient safety culture in hospital settings. The purpose of this study was to examine the multilevel psychometric properties of the survey. Methods Survey data from 331 U.S. hospitals with 2,267 hospital units and 50,513 respondents were analyzed to examine the psychometric properties of the survey's items and composites. Item factor loadings, intraclass correlations (ICCs), design effects, internal consistency reliabilities, and multilevel confirmatory factor analyses (MCFA) were examined as well as intercorrelations among the survey's composites. Results Psychometric analyses confirmed the multilevel nature of the data at the individual, unit and hospital levels of analysis. Results provided overall evidence supporting the 12 dimensions and 42 items included in the AHRQ Hospital Survey on Patient Safety Culture as having acceptable psychometric properties at all levels of analysis, with a few exceptions. The Staffing composite fell slightly below cutoffs in a number of areas, but is conceptually important given its impact on patient safety. In addition, one hospital-level model fit indicator for the Supervisor/Manager Expectations & Actions Promoting Patient Safety composite was low (CFI = .82), but all other psychometrics for this scale were good. Average dimension intercorrelations were moderate at .42 at the individual level, .50 at the unit level, and .56 at the hospital level. Conclusions Psychometric analyses conducted on a very large database of hospitals provided overall support for the patient safety culture dimensions and items included in the AHRQ Hospital Survey on Patient Safety Culture. The survey's items and dimensions overall are psychometrically sound at the individual, unit, and hospital levels of analysis and can be used by researchers and hospitals interested in assessing patient safety culture. Further research is needed to study the criterion-related validity of the survey by analysing the relationship between patient safety culture and patient outcomes and studying how to improve patient safety culture.

The objective of this study is to conduct a baseline assessment of patient safety culture in Lebanese hospitals. The study adopted a cross-sectional research design and utilized the hospital survey on patient safety culture (HSOPSC). Sixty-eight Lebanese hospitals participated in the study (54% of all hospitals). A total of 6807 hospital employees participated in the study including hospital-employed physicians, nurses, clinical and non-clinical staff, and others. The HSOPSC measures 12 composites of patient safety culture. Two of the composites (frequency of events reported and overall perception of safety), in addition to questions on patient safety grade and number of events reported, are the four outcome variables. Survey respondents were primarily employed in medical and surgical units. The dimensions with the highest positive ratings were teamwork within units, hospital management support for patient safety, and organizational learning and continuous improvement, while those with lowest ratings included staffing and non-punitive response to error. Approximately 60% of respondents reported not completing any event reports in the past 12 months and over 70% gave their hospitals an 'excellent/very good' patient safety grade. Bivariate and multivariate analysis revealed significant differences across hospitals of different size and accreditation status. Study findings provide evidence that can be used by policy makers, managers and leaders who are able to create the culture and commitment needed to identify and solve underlying systemic causes related to patient safety.
