Objective: We sought to understand the landscape of published articles regarding medical schools' learning environments (LE) worldwide, with an explicit focus on potentially harmful aspects of the LE as an effort to identify areas specifically in need of remediation or intervention that could prevent future unprofessional behaviors, burnout, violence and mistreatment among students and physicians.
Methods: A bibliometric analysis was conducted in six electronic databases (PubMed/Medline, Web of Science, Cochrane Library, SCOPUS, ERIC-ProQuest, and PsycINFO) up to December 31, 2016, including 12 themes: learning environment - general, hidden curriculum (harmful), unethical behaviors, bullying/hazing, violence, sexual discrimination, homophobia, racism, social discrimination, minorities discrimination, professional misconduct, and other negative aspects.
Results: Of the 9,338 articles found, 710 met the inclusion criteria. The most common themes were general LE (233 articles), unprofessional behaviors (91 articles), and sexual discrimination (80 articles). Approximately 80% of articles were published in the 21st century.
Conclusion: There is a definite increase in scientific articles on negative aspects of the medical school LE in high-quality journals, especially in the 21st century. However, more studies are needed to investigate negative LE aspects with greater attention to experimental, longitudinal, and cross-cultural study designs.
