This study explores how leadership styles and organizational culture influence healthcare professionals’ engagement, performance, and patient care within the NHS, addressing a gap in understanding their combined impact on healthcare outcomes. While leadership and culture are key drivers of healthcare success, they are often studied separately. This research examines their intersection, focusing on transformational leadership and a patient-centric organizational culture. Using a qualitative approach, semi-structured interviews were conducted with healthcare professionals from NHS hospitals in the United Kingdom. Data were analyzed thematically through the lens of transformational and transactional leadership theories and Edgar Schein’s organizational culture framework. The findings reveal three key themes: transformational leadership enhances motivation, performance, and engagement by fostering a supportive work environment; a patient-centric culture strengthens collaboration, teamwork, and high-quality care through shared values; and professional engagement, shaped by leadership and culture, plays a crucial role in job satisfaction and patient outcomes. By integrating leadership and organizational culture, this study offers new insights into their collective impact on healthcare performance. It highlights the need for leadership development programs that promote transformational leadership and patient-centered culture. Future research should further investigate the direct link between leadership, culture, and patient outcomes across different healthcare settings.
