From Administrative Systems to Patient Outcomes: A Structural Equation Model of Nursing Clinical Performance in Healthcare Organizations

Background: Administrative systems play a critical role in healthcare delivery, yet their influence on nursing clinical performance and patient outcomes remains underexplored within integrated organizational models. Inefficient documentation processes, fragmented information systems, and communication barriers contribute to increased nursing workload, burnout, missed care, and compromised patient safety. In the Philippine healthcare system, these challenges are intensified by workforce shortages, uneven technological infrastructure, and increasing administrative demands associated with Universal Health Care implementation. Objective: This study examined the direct and indirect effects of administrative system efficiency on nursing clinical outcomes and patient outcomes, identified key mediating organizational mechanisms, and developed an evidence-based intervention framework for healthcare organizations. Methods: A cross-sectional explanatory study was conducted among 200 healthcare professionals from three tertiary hospitals in the Philippines. Participants included staff nurses, nurse administrators, and administrative personnel selected through stratified sampling. Data were gathered using validated five-point Likert-scale instruments measuring administrative system efficiency, organizational mediators, nursing clinical outcomes, and patient outcomes. Structural Equation Modeling (SEM) using maximum likelihood estimation was employed to test hypothesized relationships. Mediation effects were assessed using bootstrapping with 5,000 resamples. Model adequacy was evaluated using χ²/df, Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA), and Standardized Root Mean Square Residual (SRMR). Results: Administrative system efficiency significantly predicted nursing clinical outcomes (β = .28, p
