The association between experience of hospital accreditation and nurses’ perception of patient safety culture in South Korean general hospitals: a cross-sectional study

BACKGROUND: Hospital accreditation programs can positively affect nurses’ perceptions of patient safety culture. However, no previous research has identified the association between experience of hospital accreditation and nurses’ perception of patient safety culture in general hospitals. This study aims to examine 1) the level of perception of each area of patient safety culture in nurses working in general hospitals and 2) the relationship between experience of hospital accreditation and nurses’ overall perceptions of safety in Korean general hospitals. METHODS: A cross-sectional survey design was used, with a convenience sample of 310 nurses from six general hospitals. Nurses were asked to complete the self-reported Korean version of the Hospital Survey on Patient Safety Culture and the experience of hospital accreditation. A hierarchical multiple regression analysis was used to examine the associations between hospital accreditation experience and perception of patient safety culture. RESULTS: The patient safety composites with the highest positive response were the frequency of events reported (90.6) and supervisor/manager expectations promoting patient safety (69.4%). The composites with the lowest scores were non-punitive responses to errors (22.9%) and organizational learning/continuous improvement (35.5%). Hierarchical multiple regression analysis showed that the experience of hospital accreditation had a very small increase on overall perceptions of safety (β = 0.097, p = 0.023). CONCLUSIONS: This study found that general hospital nurses’ experience of hospital accreditation had very weak relationship with their overall perceptions of patient safety. Therefore, a longitudinal study is needed to confirm the influence of hospital accreditation on nurses’ patient safety culture in general hospitals.
