Overview

Cross-sectional study examines anesthesiologist work periods and patient outcomes in surgical settings, highlighting safety implications.

Key Points

  • To determine how extended work periods for anesthesiologists affect postoperative patient outcomes.
  • Cross-sectional analysis of data from the Multicenter Perioperative Outcomes Group registry.
  • Involved 1,648,720 surgical procedures and 1,711 anesthesiologists across 36 institutions.
  • Compared outcomes during extended work periods (16 hours or more) versus standard work periods.
  • No significant difference in the composite outcome (12.3% vs 12.0%; P = .82).
  • In-hospital mortality was higher for extended work periods (1.3%) compared to standard work periods (1.0%; P = .009).
  • Sensitivity analyses suggested small increases in risks for other outcomes as well.
