Predictive model identifies high-risk patients for incisional infections

A study involving 329 patients with acute intestinal obstruction revealed that 11.25% developed postoperative incisional infections, primarily caused by gram-negative bacteria like Escherichia coli. High resistance rates to ceftriaxone were noted. Researchers developed a predictive model using six significant variables: age ≥ 60 years, diabetes, operative time ≥ 3 hours, colorectal obstruction, enterostomy, and hemoglobin. The model demonstrated excellent discriminatory ability, with AUCs of 0.952 and 0.982 for training and validation sets, respectively.
