## Abstract

Background: Knowledge sharing is essential for healthcare organizations to enhance service quality, organizational learning, and sustainable performance. However, the organizational and individual conditions that facilitate voluntary knowledge sharing among healthcare workers remain insufficiently explored. Methods: This cross-sectional study surveyed healthcare employees working in hospital organizations in Taiwan. A total of 355 valid questionnaires were analyzed using SPSS 22. Descriptive statistics, correlation analysis, hierarchical regression analysis, and mediation testing were conducted to examine the relationships among organizational justice, perceived organizational support, computer self-efficacy, organizational citizenship behavior (OCB), and knowledge sharing. Results: The results indicated that organizational justice, perceived organizational support, and computer self-efficacy were positively associated with organizational citizenship behavior. Organizational citizenship behavior, in turn, had a significant positive effect on knowledge sharing. Moreover, organizational citizenship behavior partially mediated the relationships between organizational justice and knowledge sharing, as well as between perceived organizational support and knowledge sharing. In contrast, the mediating effect of organizational citizenship behavior between computer self-efficacy and knowledge sharing was not supported. Conclusions: The findings highlight the pivotal role of organizational citizenship behavior in translating favorable organizational conditions into knowledge-sharing behaviors in healthcare settings. Creating fair and supportive organizational environments appears to be more critical than individual technical confidence alone in promoting sustainable knowledge sharing among healthcare workers.
