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).
