Publication Trends in Research on Mental Health and Mental Illness in Orthopaedic Surgery

Abstract

Background:Mental health conditions affect tens of millions of Americans. In recent years, particularly with the advent of the coronavirus disease 2019 pandemic, there has been a burst of interest in mental health and mental illness among orthopaedic surgical patients. The mental health of orthopaedic surgeons themselves has also come into focus, with high reported rates of burnout and depression. The aim of this article was to evaluate trends in publication on mental health and mental illness in orthopaedic surgery.Methods:Web of Science and PubMed were queried to conduct a systematic review. Studies that discussed orthopaedic surgery and mental illnesses or mental health topics over 2001 to 2022 were included. Publications were analyzed by article-, author-, and topic-level characteristics.Results:A total of 416 studies were analyzed after application of inclusion and exclusion criteria. Publication volume increased dramatically, demonstrating quadratic growth over 2001 to 2022 (p < 0.001). Eighty-eight percent of studies focused on patients and 10% on surgeons, with studies about patients more likely to focus on mental illness and those about surgeons more likely to focus on mental health (p < 0.001). Twenty percent of publications had a female senior author, and 5 authors collectively accounted for 10% of all publications. Eight journals published more than 10 publications, accounting for 35% of all publications. The most productive subspecialties were arthroplasty (135, 30%), general orthopaedics (87, 21%), and spine (69, 17%). Mental illnesses that were least represented included schizophrenia, bipolar disorder, eating disorders, attention-deficit/hyperactivity disorder, and personality disorders (1% or less of total publications each).Conclusion:This analysis showed a dramatically increasing trend in publications on mental health and mental illness in orthopaedic surgery. A high concentration of publications came from a subset of journals and senior authors, and women were overrepresented as senior authors relative to their representation in the field. The results of this analysis identified gaps in the literature, including underrepresented subspecialties, understudied mental illnesses, and study of orthopaedic surgeon mental health, and thus highlighted areas for future investigation.Level of Evidence:Therapeutic Level IV.
