Abstract
BACKGROUND: This study hypothesizes that resident involvement in research has increased since institution of the maximum 80-hour workweek in 2002. METHODS: All 571 papers published in the Journal of Bone and Joint Surgery (JBJS) in 1997 and 2007 (five years before and after the start of the 80-hour workweek) were reviewed. To identify resident authors, a search was performed in the American Board of Orthopaedic Surgery (ABOS) database for any U.S. author with a medical doctorate (MD). Any authors who were board-certified more than two years after the publication date were identified as "residents." Two-tailed Fisher's exact tests were used to assess proportional changes over time. RESULTS: Between 1997 and 2007, the percentage of U.S. MD authors who were orthopaedic residents increased significantly from 12% to 18% (p = 0.01). U.S. publications with a resident first-author increased from 17% to 27% (p = 0.02), and contributions from foreign nations also increased significantly (p < 0.001). The number of total authors per paper increased (p < 0.001), but linear regression showed that this had no particular association with the proportion of residents (p = 0.20). The relative proportions of MD and non-MD authors did not change between years. The LOE of resident-authored papers improved significantly over time (p = 0.005), while that of international papers did not. CONCLUSIONS: Proportional resident authorship has increased significantly in one of the highest-impact, peer-reviewed orthopaedic journals. LOE of resident-authored papers has improved, and basic science papers are more likely to have a resident first author. LEVEL OF EVIDENCE: III, retrospective cohort study.
