Psychometric Properties of the Hospital Survey of Patient Safety Culture in Type A Hospitals in Kingston and St. Andrew, Jamaica

This study sought to examine the internal consistency reliability and underlying factor structure of the Agency of Health Research on Quality Hospital Survey on Patient Safety Culture (AHRQ HSOPSC) in two large acute care hospitals in a developing country setting (Jamaica). A cross-sectional study was done among 328 doctors and nurses. Reliability (internal consistency) analysis was done for each of the 12 composites and the Cronbach's Alpha coefficients were reported. Principal axis factor analysis (PA) using Varimax rotation was done to identify the underlying factor structure. The Cronbach's Alpha coefficient was >= 0.60 in ten composites. 'Overall perception of patient safety' and 'staffing' had Cronbach's Alpha values of 0.585 and 0.553 respectively. A ten-factor solution (34 items) with factor loading of >= 0.40 is the best model fit, and composites are now named 'handoff and transitions/information exchange,' 'communication/feedback,' 'frequency of events reported,' 'management support for patient safety,' 'teamwork in unit,' 'non-punitive response to errors,' 'overall perception of patient safety,' 'supervision/management expectations and actions promoting patient safety,' 'organizational learning - continuous improvement' and 'staffing'. The AHRQ HSOPSC is generally reliable in this developing country setting and the ten-factor structure is consistent with suggested modifications for the emergent AHRQ HSOPSC Version 2 tool.
