Outcomes? Multiple Centers Community Academic

Data National. Validated. Risk-adjusted Outcomes-based 30 day mortality/morbidity

Data: ,391 patients had Lap IHR 4,168 had: CABG, Vasectomy… 6,223 Lap IHR only

Results Mean Age 53 yrs (16-90) OR Time 63 mins (6-303) 92% 8%

Results % Emergent <1 Bilateral 21 Recurrent 13 Resident 57

Operative Time Minutes Staff Alone PGY-1PGY-2PGY-3PGY-4PGY> P < = 21 mins As PGY operative time P < mins Staff Staff + Resident 72 mins

Duration of Stay Mean Median Staff Staff + Resident >1d >2d Odds Ratio P<0.001

Complications Infections Return to OR Nerve Injury Pneumonia Unplanned intubation UTI Dehiscence DVT/PE Renal Failure SepsisDeath Groin pain, Recurrence, Urinary Retention?

Staff 1.4% Staff + Res 1.7% PGY vs PGY: all p > 0.4 p = 0.3 Complications

Mayo vs World Mayo Academic Community Comp. Inpatient 0.9% 1.3% 0.9% 33% 10% 5%

Conclusions Solo staff surgeons are faster Shorter time with juniors vs senior

Conclusions Res + Staff: odds of longer hospital stay Sr. vs Jr. : odds of longer hospital stay

Conclusions NO Difference: - in M&M when residents “participate” - in M&M by resident PGY level

Weaknesses NSQIP: Academic over represented Complications Resident participation? TEP vs TAPP?
