Table 3:

Adjusted odds ratios for the effect of surgeon age^* on outcomes in patients undergoing emergent and elective surgery^†

Outcome	OR (95% CI)		p value for interaction
	Emergent surgery	Elective surgery
Primary composite outcome (death, readmission or complication within 30 d)	0.97 (0.94–0.99)	0.96 (0.93–0.99)	0.3
Death within 30 d	0.98 (0.96–1.01)	0.96 (0.91–1.01)	0.25
Readmission within 30 d	1.00 (0.99–1.02)	0.98 (0.97–0.99)	0.002
Complication within 30 d	0.94 (0.91–0.98)	0.94 (0.89–0.999)	0.97
Ratio of means for hospital LOS	1.01 (1.01–1.02)	Did not converge

Note: ADG = Aggregated Diagnosis Group, CI = confidence interval, LOS = length of stay, OR = odds ratio.

^*Younger than 65 years versus 65 years and older.

^†We adjusted for patient sex, age, income quintile, geographic region of residence, rurality and comorbidity (ADG score); index operative year; surgeon sex; surgeon specialty; and hospital type (academic v. community).
