Have Residents Produced More Research Since the Inception of the 80-Hour Workweek?

This study hypothesizes that resident involvement in research has increased since institution of the maximum 80-hour workweek in 2002.

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.

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.

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.
