RESUMEN
AIM: To examine and summarize the reported association of nurse managers' transformational leadership and quality of patient care based on the perceptions of registered nurses. BACKGROUND: Transformational leadership behaviors of nurse managers result in staff nurses' satisfaction and retention and patient satisfaction. Patient safety and quality of care are vital to high-performing healthcare organizations. Perceptions of registered nurses are important because nurses are frontline healthcare providers fundamental to patient safety and quality of care and are considered the final line of defense in preventing adverse events and errors and improving the safety of patients. MATERIALS AND METHODS: We searched the CINAHL, ProQuest, PubMed, Science Direct, and Web of Science databases for evidence published between 2018 and 2022 in the English language. We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in carrying out this meta-analysis. RESULTS: Nine quantitative studies were appraised using the Joanna Briggs Institute checklists and were included in the final review that involved a total sample of 3633 registered nurses. The included studies were reported across Asian, Middle East, and European countries within the past five years. The association between the transformational leadership behaviors of nurse managers and the quality of patient care was found in varying degrees (i.e., insignificant, weak, indirect, and strong direct association) based on the perceptions of registered nurses. CONCLUSIONS: There is a direct and indirect association between the transformational leadership behaviors of nurse managers and the quality of patient care internationally. This association is influenced by confounding and mediating factors, including gender, organizational culture, structural empowerment, and job satisfaction. IMPLICATIONS FOR NURSING AND HEALTH POLICIES: Healthcare organizations need to support nursing leaders to have a stronger transformational leadership style by considering several factors that influence their leadership to improve the quality of patient care their staff nurses provide at the bedside.
