Classifier errors (optimized GTB-Stem) for the different types of HAIs.
| Label | Errors | Dataset |
|---|---|---|
| Ventilator-associated pneumonia | 0 | 8 |
| Sepsis | 1 | 46 |
| Pneumonia | 1 | 33 |
| Other HAI | 1 | 15 |
| Fungus/virus | 1 | 15 |
| Central venous catheter–related HAI | 1 | 10 |
| Wound infection | 2 | 25 |
| Urinary tract infection | 4 | 20 |
| Clostridium difficile | 2 | 10 |
GTB: gradient tree boosting.
A hospitalization marked with HAI may have one or more types of HAI. Hence, a misclassified HAI hospitalization may contribute to the number of errors for multiple labels.
