<![CDATA[Patient safety is a core pillar of healthcare quality, with facility and safety management (FSM) as a key determinant of medical equipment reliability. At RSUD Pasar Minggu, the ratio of IPSRS technicians to medical equipment is low (1:58), maintenance is dominated by corrective actions (88%) over preventive ones (12%), and equipment damage is under-reported. A preliminary survey showed that workflow coordination, incident communication, reporting data quality, and patient safety were all rated low, while the mediating role of reporting data quality had never been simultaneously tested. This study analyzes the effect of workflow coordination and incident communication on patient safety, both directly and through reporting data quality as a mediator. Using an explanatory sequential mixed-methods approach, the quantitative phase applied CB-SEM (AMOS) with 112 respondents, followed by an FGD with 4 IPSRS informants. The model was found fit (CFI = 1.000); incident communication and workflow coordination each had a significant positive effect on reporting data quality, and reporting data quality and incident communication each had a significant positive effect on patient safety, while workflow coordination had no direct effect. Reporting data quality was proven to mediate the effect of incident communication, but not the effect of workflow coordination, on patient safety. Managerially, RSUD Pasar Minggu needs to simplify reporting workflows, strengthen a just culture, and build an integrated, data-driven reporting system.]]>
