The MP group showed higher complication rates in terms of pneumonia (OR 1.8, 95% CI, 1.62-2.0), GI bleeding (OR 1.2, 95% CI, 1.05-1.38), and UTI (OR 1.68, 95% CI, 1.53-1.84).
Determined by AUC C-stat and Brier scores, prediction was good for cardiac complications (0.80 and 0.021), fair for pneumonia (0.75 and 0.017), poor for UTI (0.64 and 0.078), 30-day mortality (0.62 and 0.013), any complication (0.60 and 0.19) and serious complication (0.60 and 0.17).
Postoperative index UTI was associated with increased risk of sepsis (21.4% vs. 0%; OR, 49.2; 95% CI: 14.5-166.8; P < 0.001), pneumonia (10.7% vs. 2.9%; OR, 4.0; 95% CI: 1.8-8.6; P = 0.001), DVT (3.6% vs. 0.4%; OR, 10.0; 95% CI: 1.8-55.5; P = 0.008), and mortality (5.4% vs. 1.8%; OR, 3.0; 95% CI: 1.1-8.5; P = 0.02).
