Cox proportional hazards model estimates of readmission and death of matched-pairs analysis, Clostridium difficile–associated disease (CDAD)*
| Variable | CDAD case-patients, no. (%) | Controls, no. (%) | Hazard ratio (95% CI) |
|---|---|---|---|
| Readmitted within 180 d† | 148 (51.0) | 92 (31.7) | 2.17 (1.59–2.95) |
| Deaths at 180 d‡ | 127 (36.0) | 107 (30.3) | 1.22 (0.92–1.61) |
| Deaths at 0–60 d‡ | 72 (20.4) | 75 (21.2) | 0.96 (0.54–1.70) |
| Deaths at 61–180 d‡ | 55 (15.6) | 32 (9.1) | 2.00 (1.47–2.72) |
*CI, confidence interval.
†n = 290 matched pairs; 63 matched pairs were excluded because one or both patients in the pair died during the index hospital admission.
‡n = 353 matched pairs.
