Wound complications – multivariable logistic regression
On multivariable logistic regression, cancer diagnosis had no association with odds of suffering an aggregate wound complication (aOR 0.27, 95% C.I. 0.05-1.39) or any individual wound complication (for SSI, aOR 0.40, 95% C.I. 0.03-5.47; for abscess, aOR 0.30, 95% C.I. 0.04-2.34); for other categories too few counts to calculate aOR) (Table 3). Those factors that did have an association with odds of suffering an aggregate wound complication were: WBC 1001-2000 vs WBC ≥3000 (aOR 6.16, 95% C.I. 1.60-23.75); laparoscopic vs open operation (aOR 0.73, 95% C.I. 0.59-0.86); perforated vs non-perforated appendicitis (aOR 4.75, 95% C.I. 4.19-5.38); non-white vs white race (aOR 1.22, 95% C.I. 1.07-1.39); and increasing ASA Class (Table 4).
