Abstract
Background: Patient safety culture is measured using a range of survey tools. Many provide limited data on psychometric properties and few report findings outside of the USA healthcare context. This study reports an assessment of the psychometric properties and suitability of the American Hospital Survey on Patient Safety Culture (HSOPC) for use within the UK.
Methods: A questionnaire survey of three hospitals within a large UK Acute NHS Trust. 1,437 questionnaires were completed (37% response rate). Exploratory factor analysis, confirmatory factor analysis, and reliability analyses were carried out to assess the psychometric performance of this survey instrument and explore potential improvements.
Results: Reliability analysis of the items within each proposed scale showed that over half failed to achieve satisfactory internal consistency (Cronbach’s Alpha < 0.7). Furthermore, a confirmatory factor analysis carried out on the UK dataset achieved a poor fit when compared to the original American model. An optimal measurement model was then constructed via exploratory and confirmatory factor analysis with split-half sample validation, and consisted of 9 dimensions compared to the original 12 in the American model.
Conclusion: This is one of the few studies to provide an evaluation of an American patient safety culture survey using data from the UK. The results indicate that there is need for caution in using the HSOPC survey in the UK and underline the importance of appropriate validation of safety culture surveys before extending their usage to populations outside of the specific geographical and health care contexts in which they were developed.
