Table 2.

Postoperative adverse outcomes associated with any 30-day SSI. Outcomes were excluded from the SSI group if they occurred before SSI (except still in hospital > 30 days).

Outcome	SSI, n (%)	No SSI, n (%)	Days from SSI to Complication (mean ± SD)	OR	95% CI	P
Wound disruption	31 (12.4)	103 (1.1)	0.9 ± 3.3	12.233	8.012–18.678	<0.001
Sepsis	39 (15.5)	27 (0.3)	0.7 ± 2.0	61.443	36.925–102.243	<0.001
UTI	4 (1.6)	95 (1.1)	7.0 ± 12.7	1.526	0.557–4.182	0.408
Unplanned reintubation	2 (0.8)	73 (0.8)	2.0 ± 2.8	0.987	0.241–4.045	0.986
Death	0 (0)	26 (0.3)	N/A	N/A
Readmission within 30 days postop, n (%)	92 (36.7)	761 (8.4)	1.4 ± 4.1	6.299	4.821–8.228	<0.001
Reoperation within 30 days postop, n (%)	109 (43.4)	473 (5.2)	1.7 ± 3.7	13.911	10.660–18.154	<0.001
Still In hospital >30 days, n (%)	18 (7.2)	111 (1.2)	N/A	6.218	3.716–10.404	<0.001

Statistical analysis was performed using Chi square test and Fisher’s exact test where appropriate.

UTI = urinary tract infection; SD = standard deviation from the mean; OR = odds ratio; CI = confidence interval
