Purpose/Aim: This project analyzed the psychometric properties of the AHRQ Hospital Survey on Patient Safety Culture (HSOPSC) including factor structure, inter-item reliability and intra-class correlations, usefulness for assessment, predictive validity, and sensitivity. Background: The HSOPSC was developed for the Agency of Healthcare Research and Quality and comparative data for 519 hospitals in the United States became available in 2008. This tool is composed of 42 items that are separated into subscales to measure the 12 sub-dimensions of safety culture. In addition there are 2 single item measures of outcomes. The HSOPSC's has come into common use in U.S. hospitals. Hospital safety teams and quality improvement departments are using the HSOPSC dimension scores to diagnose strengths and weaknesses of their safety culture. Methods: The survey was administered to 454 healthcare staff in 3 hospitals before and after a series of multidisciplinary interventions designed to improve safety culture. Respondents (434 before, 368 after) included nurses, physicians, pharmacists, and other hospital staff members. Results: Factor analysis partially confirmed the validity of the HSOPSC subscales. Inter-item consistency reliability was above .7 for five subscales; the Staffing subscale had the lowest reliability coefficients. The intra-class correlation coefficients, agreement among the members of each unit, were within recommended ranges. The pattern of high and low scores across the subscales of the HSOPSC in the study hospitals were similar to the sample of Pacific region hospitals reported by AHRQ and corresponded to the proportion of items in each subscale that are worded negatively (reverse scored). Most of the unit and hospital dimensions were correlated with the Safety Grade outcome measure in the tool. Implications: Overall the tool was shown to have moderate to strong validity and reliability, with the exception of the staffing subscale. The usefulness in assessing areas of strength and weakness for hospitals or units among the culture subscales is questionable. The culture subscales were shown to correlate with the outcomes scales but further study is needed to determine true predictive validity.
