Interprofessional Team Collaboration as a Mediator Between Workplace Social Capital and Patient Safety Climate: A Cross-Sectional Study

Abstract

Background and Objectives: Patient-safety climate is one of the most important organizational factors contributing to health care quality. We hypothesized that a patient safety climate is fostered by the willingness to collaborate and trust among members as well as by daily collaborative practices. This study aimed to clarify the effect of workplace social capital on patient safety climate. We also sought to investigate the mediating effect of interprofessional team collaboration on the relationship between workplace social capital and patient safety climate. Methods: This cross-sectional survey was conducted from November 2021 to January 2022 using anonymous web-based questionnaires. The survey was distributed to 1495 employees working in a hospital in Tokyo, Japan. The questionnaire included the patient safety climate scale, workplace social capital scale, Japanese version of the Assessment of Interprofessional Team Collaboration Scale-II (AITCS-II-J), and demographic items. Structural equation modeling was performed to verify the associations among the 3 variables. In addition, a significance test for indirect effects was conducted using the bootstrap method to confirm the mediating effect of AITCS-II-J. Results: A total of 725 employees participated in this survey, and 632 data items were analyzed. Nurses were the highest number of respondents (68.2%), followed by physicians (13.3%). Workplace social capital and patient safety were directly and significantly associated (β = .309, P < .01). Furthermore, the partially indirect effect of the AITCS-II-J on the association between workplace social capital and patient safety climate was also significant (β = .430, P < .01). Conclusions: Workplace social capital was significantly and directly related to patient safety climate and was also significantly related to patient safety climate partially mediated by interprofessional team collaboration. Our findings suggest the importance of workplace social capital and routine multidisciplinary collaboration for a patient safety climate to manage health care quality.
