Given the increasing focus on patient safety in healthcare systems worldwide, understanding the impact of Continuous Quality Improvement Programs (QIPs) is crucial. QIPs, including Morbidity and Mortality Conferences (MMCs) and Experience Feedback Committees (EFCs), have been identified as effective strategies for enhancing patient safety culture. These programs engage healthcare professionals in the identification and analysis of adverse events to foster a culture of safety (ie the product of individual and group value, attitudes, and perceptions about quality and safety). This study aimed to determine whether patient safety culture differed regarding care provider participation in MMCs and EFCs activities. A cross-sectional web-only survey was conducted in 2022 using the Hospital Survey on Patient Safety Culture (HSOPS) among 4780 employees at an 1836-bed, university-affiliated hospital in France. We quantified the mean differences in the 12 HSOPS dimension scores according to MMCs and EFCs participation, using Cohen d effect size. We performed a multivariate analysis of variance to examine differences in dimension scores after adjusting for background characteristics. Of 4780 eligible employees, 1457 (30.5%) participated in the study. Among the respondents, 571 (39.2%) participated in MMCs or EFCs activities. Participants engaged in MMCs or EFCs reported significantly higher scores in six out of twelve HSOPS dimensions, particularly in "Nonpunitive response to error", "Feedback and communication about error", and "Organizational learning" (Overall effect size = 0.14, 95% confidence interval = 0.11 to 0.17, P<0.001). Notably, involvement in both MMCs and EFCs was associated with higher improvements in patient safety culture compared to non-participation or singular involvement in either program. However, certain dimensions such as "Staffing", "Hospital management support", and "Hospital handoffs and transition" showed no significant association with MMCs or EFCs participation, highlighting broader systemic challenges. The study confirms the positive association between participation in MMCs or EFCs and an enhanced culture of patient safety, emphasizing the importance of such programs in fostering an environment conducive to learning, communication, and nonpunitive responses to errors. While MMCs or EFCs are effective in promoting certain aspects of patient safety culture, addressing broader systemic challenges remains crucial for comprehensive improvements in patient safety.
