Patient Safety Subcultures among Nursing Home Staff in Italy: A Cross-Sectional Study.

Nursing home (NH) residents are vulnerable subjects and highly susceptible to adverse events. Knowledge of patient safety culture (PSC) is essential for an organization to ensure patient safety. However, research on PSC in NHs, and its variability among staff, is still scarce. This study aimed to explore whether and how PSC differed among NH staff (Managers, Nurses, Direct Care Staff, Support Staff, Administrative Staff and Other Providers) in the Autonomous Province of Trento, Italy. This study employed a cross-sectional design and collected data from 1145 NH providers using the Nursing Home Survey on Patient Safety Culture (NHSPSC). Data were analyzed using linear mixed models, with each of the 12 NHSPSC domains as a response variable. The majority of the respondents (61.6%) were Direct Care Staff members. 'Feedback and Communication about Incidents' and 'Overall Perceptions of Resident Safety' were the domains with the highest proportions of positive answers (PPAs). For most staff categories, 'Staffing' was the domain with the lowest PPA. Support Staff showed significantly lower scores in the majority of domains (8/12). Shorter job tenure, fewer weekly working hours, working mostly during the day and working in highly specialized areas were associated with higher scores in several domains. Interventions to improve PSC must consider the differences between professional groups. Further research is needed to explore the relationship between job-related features and perceptions of patient safety among NH workers.
