This study endeavors to explore the bibliometric analysis and visualization with regard to the intellectual and thematic evolution and implications of emotional intelligence (EI) in the healthcare sector. Bibliometric data were extracted from the Scopus database through a structured query and then analyzed with the help of software such as R-Bibliometrix, Python, and VOSviewer. This study accounted for 543 documents authored by 1,863 researchers from 61 different countries, reflecting an annual growth rate of 15.02%. The United Kingdom and the United States evolved as the most productive countries, and The International Journal of Environmental Research and Neuroscience ranked as the top publishing source. Emphasizing EI’s relationship to doctor burnout, job satisfaction, and patient satisfaction, Weng emerged as the most cited author. Co-occurrence and conceptual analysis of the studies revealed three thematic clusters: Emotional Intelligence and healthcare quality, psychological well-being, and healthcare organizations. Emerging trends emphasize burnout, empathy, tele-medicine, and resilience during crises such as the COVID-19 pandemic. These studies highlight the increasing interdisciplinary significance of Emotional Intelligence in enhancing clinical competence, patient care, and healthcare system performance.
