  1. All cases performed with an Anesthesiology Resident or CRNA/CAA were performed with a supervising Anesthesiologist who was required to be physically present for induction and extubation (as indicated) for all cases
  2. Data are presented as mean ± standard deviation, median [25th percentile-75th percentile], or percent
  3. Data were analyzed using SPSS 27 with a one-factor ANOVA, Kruskal-Wallis, or a Chi-Square test. P-values were adjusted to account for multiple comparisons between groups
  4. † = p < 0.05 comparing Anesthesiologist group data to Resident and CRNA/CAA group data
  5. * = p < 0.05 comparing Resident group data to Anesthesiologist and CRNA/CAA group data
  6. CRNA certified registered nurse anesthetist
  7. CAA certified anesthesiologist assistant
  8. MAP mean arterial pressure
  9. Min minutes
  10. AHRQ Agency for Healthcare Research and Quality
  11. MPOG Multicenter Perioperative Outcomes Group
  12. AKI acute kidney injury
