- *Factors excluded from the model for collinearity: chronic kidney disease, hemodialysis, chronic obstructive pulmonary disease, diabetes mellitus (collinear with congestive heart failure); hospital-acquired blood stream infection, LOS prior to the onset of sepsis (collinear with prior antibiotics); Charlson comorbidity score (collinear with age)’ mechanical ventilation, vasopressors (collinear with APAHCE II); carbapenem resistance (collinear with non-IAAT).
- Factors included but not retained in the model at the p < 0.05: congestive heart failure, chronic liver disease, prior antibiotics, age, prior hospitalization, polymicrobial infection, infection sources urine and abdomen.
- IAAT = initially appropriate antibiotic therapy.
- AUROC =0.801, Hosmer-Lemeshow p = 0.406.
