This study examines the impact of employee well-being on patient experience in private hospitals, with job satisfaction acting as a mediating variable. Grounded in the Job Demands-Resources (JD-R) framework and Social Exchange Theory, the research aims to provide a comprehensive understanding of how internal employee-related factors influence external service outcomes in healthcare settings. A quantitative, cross-sectional research design was employed, collecting data from a diverse sample of healthcare employees and patients in private hospitals in Saudi Arabia. A total of 320 employee responses and 200 patient responses were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS software. The results indicate that employee well-being has a significant positive effect on job satisfaction, which in turn significantly enhances patient experience. While employee well-being also demonstrates a direct effect on patient experience, this effect is comparatively weaker than the indirect effect facilitated through job satisfaction. Mediation analysis confirms that job satisfaction partially mediates the relationship between employee well-being and patient experience, suggesting that employee attitudes play a crucial role in translating well-being into service performance. These findings underscore the importance of integrating human resource practices with patient-centered strategies, especially in light of Saudi Arabia’s healthcare transformation under Saudi Vision 2030. This study contributes to the literature by presenting an integrated model linking employee well-being, job satisfaction, and patient experience, and it offers practical implications for improving healthcare service quality.
