Abstract
INTRODUCTION: Professionalism is a core concept in medicine. The extent to which knowledge about professionalism is anchored in empirical research is unknown. Understanding the current state of research is necessary to identify significant gaps and create a road map for future professionalism efforts. The authors conducted an exploratory literature review to characterize professionalism research published in widely read medical journals, identify knowledge gaps, and describe the sources of funding for the identified studies. METHODS: The authors focused on Medline's Abridged Index Medicus and 4 core Medline education-oriented journal and developed a search filter using text words found in the article title or abstract addressing professionalism. Articles were further filtered to include those indicating a research focus. RESULTS: The search strategy resulted in 461 professionalism research articles for analysis. Articles were divided into themes of education (n = 212, 45.9%), performance (n = 83, 18%), measurement development (n = 13, 2.8%), remediation (n = 53, 11.5%), and well-being (n = 100, 21.6%). There were 36 studies from 1980 to 2002 (Era 1: before publication of Accreditation Council for Graduate Medical Education competencies) and 425 from 2003 to 17 (Era 2: after Accreditation Council for Graduate Medical Education publication of competencies). Professionalism education was the most common topic area, and most studies were from single institutions with results based on convenience samples. Most studies received no funding or were funded by the authors' own institution. DISCUSSION: Little empirical research is available on professionalism in widely read medical journals. There has been limited external research funding available to study this topic. CONCLUSION: More investment in high quality professionalism research is justified and should be encouraged.
