Research Article: Relationship between adverse events prevalence, patient safety culture and patient safety perception in a single sample of patients: a cross-sectional and correlational study

Date Published: 2023-08-24

Abstract:
Objective To assess the relationship between adverse events prevalence (AEP), patient safety culture (PSC) and patient safety perception (PSP). Design Cross-sectional, ex post facto comparative study on a single sample of patients. Setting Four medium-high-level hospitals were included in the study—two public and two private from Zulia State in Venezuela. Participants 556 medical records and patients were studied for the prevalence and PSP study, and 397 of the healthcare providers involved in the care of these patients were surveyed for the PSC study, at two public and two private hospitals. Outcome measurement The primary outcome of this study was the association between AEP, PSC and PSP, and according to hospital funding type, private and public. Results An inverse association was observed between AEP and its severity and Patient Safety Culture Index (rho=?0.8, p=0.5) (95% CI 0.26–0.10) and Patient Safety Perception Index (rho=?0.6, p=0.18) (95% CI 0.10–0.28), which were protective factors for patient safety. No association was identified between PSC and PSP (rho=0.0001). No statistical differences were identified by hospital type (p=0.93) (95% CI 0.70–1.2). Conclusions The analysis of the variable correlations studied (AEP, PSC and PSP) within the same sample offers an interesting and useful perspective. In this sample, although no correlation was observed between the three variables as an interacting set, some correlation patterns were observed between pairs of variables that could guide further studies.

Introduction:
Patient safety has been widely studied from the perspective of adverse events (AEs) and their financial impact, the quality/safety culture at institutional level and patients’ perceptions of AEs and how they are managed. Other studies in this field have adopted varied approaches in terms of their definitions of AEs, purpose, 1 2 objectives and design elements, 3 4 whether based on medical records (retrospective studies and cross-sectional studies), 5–7 or on individual follow-up care (prospective studies). 8 The…
