  1. 3GC-R third-generation cephalosporin-resistant Enterobacteriaceae, CRE carbapenem-resistant Enterobacteriaceae, ICU intensive care unit, MDRP multidrug-resistant Pseudomonas aeruginosa
  2. aBoldface cells = most important predictors across most models (predictors incurring the highest level of risk compared with the reference value).
  3. bComplicated urinary tract infection, complicated intra-abdominal infection, bloodstream infection, or hospital-acquired/ventilator-associated pneumonia.
  4. cPrior number of antibiotics was not included for community-acquired infection because of the difficulty of recovering accurate data
  5. dPrimary and secondary diagnoses were based on International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes
