*These variables comprised the final model and the aRR is adjusted for all other variables in the model. The full model included gender, race, age, dialysis type, incident year of dialysis, bacteremia, bacteremia+sepsis, diverticulitis, osteomyelitis, kidney transplant, peritonitis, pneumonia, UTI, urosepsis, candida colonization, cirrhosis, decubitus ulcer, diabetes, duodenal ulcer, endocarditis, esophagitis, esophageal reflux, gastric ulcer, gastrointestinal hemorrhage, glomerulonephritis, hepatitis C infection, HIV, lupus, methicillin-resistant staphylococcus aureus (MRSA) infection, peripheral vascular disease (PVD), rheumatoid arthritis, chest wall or pleural cavity incision, total parenteral nutrition (TPN), any ICU stay, number of hospitalizations 90 days before rCDI, and number of admissions 90 days before rCDI.
aRR, adjusted relative risk; ESRD, end-stage renal disease; ICU, intensive care unit; rCDI, recurrent CDI.
