Results
A total 205/9,274 (2.16%) patients with PPMs were diagnosed with a hospital-acquired SSI. Overall, the logistic regression algorithm had the highest prediction ability with the largest AUC at 72.9%. But the SVM model showed the highest sensitivity at 43.8% and positive predictive value at 32.5%. All three models showed excellent specificity and accuracy (over 98% and 96%, respectively).
