The goal was to find out key factors influencing nurse’s job satisfaction and how these qualities relate to patient care outcomes by synthesizing prior data. Methods: A literature search was conducted using four databases: PubMed, CINAHL and Embase, published from 2014 and 2023. The inclusion criteria were the impact of nurse job satisfaction on several elements of patient care quality, including safety, effectiveness, patient satisfaction, and overall health outcomes. The research quality was evaluated by established critical evaluation procedures and data were collected and synthesized utilizing standard analysis methodologies. Results: Eighteen studies satisfied the inclusion criteria, indicating a strong positive relationship between nurse work satisfaction and patient care quality. Organizational support, work environment, professional growth opportunities, and workload management were important factors in determining job satisfaction. Nurse’s high job satisfaction levels were consistently linked to increased patient safety, greater patient satisfaction scores, fewer medical mistakes and better overall patient health outcomes. Conclusion: The findings demonstrate the importance of nurse work satisfaction in improving patient care quality. Healthcare organizations should prioritize tactics that increase worker satisfaction, such as creating supportive work environments, giving opportunities for professional development, and guaranteeing acceptable workloads. By addressing these issues, healthcare systems can enhance patient outcomes and overall healthcare quality. https://ijph.tums.ac.ir/index.php/ijph/article/view/37264 https://ijph.tums.ac.ir/index.php/ijph/article/download/37264/8743
