BackgroundIn complex healthcare organizations, such as intrapartum care, both patient safety culture and teamwork are important aspects of patient safety. Patient safety culture is important for the values and norms shared by interprofessional teams in an organization, and such values are principles that guide team members’ behavior. The aim of this study was 1) to investigate differences in perceptions of patient safety culture and teamwork between professions (midwives, physicians, nursing assistants) and between labor wards in intrapartum care and 2) to explore the potential associations between teamwork and overall perceptions of patient safety and frequency of events reported. MethodsThe design was cross-sectional, using the Swedish version of the Hospital Survey on Patient Safety Culture (14 dimensions) and the TeamSTEPPS® Teamwork Perceptions Questionnaire (5 dimensions). Midwives, physicians, and nursing assistants in three labor wards in Sweden in 2018 were included. Descriptive statistics, the Kruskal–Wallis H test, two-way ANOVA, and standard multiple regression analysis were used.ResultsThe questionnaires were completed by 184 of the 365 healthcare professionals, giving a response rate of 50.4%. Two-way ANOVA showed a significant main effect of profession on two patient safety culture dimensions and one teamwork dimension and a significant main effect of labor ward on four patient safety culture dimensions and four teamwork dimensions. A significant interaction effect of profession and labor ward was found on four patient safety culture dimensions and four teamwork dimensions. The regression analysis revealed that four out of the five teamwork dimensions explained 40% of the variance in the outcome dimension ´Overall perceptions of patient safety´.ConclusionsThe results of the study indicate that profession and labor ward are important for healthcare professionals' perceptions of patient safety culture and teamwork in intrapartum care. Teamwork perceptions are significant for overall patient safety.
