Cox proportional hazards model of factors associated with all-cause in-hospital case fatality among patients with bloodstream infections due to a single organism in clinical dataset
| Variable | Hazard ratio (95% CI)a | P-valueb |
|---|---|---|
| Gender (male/female) | 1.347 (.857–2.115) | 0.196 |
| Age (1-yr. increment) | 1.008 (0.998–1.01) | 0.118 |
| Aetiology of BSI (gram-positive bacterial infection as reference) | ||
| Enterobacteriaceae infections | 2.485 (1.546–3.994) | <0.001 |
| Non Enterobacteriaceae Gram-negative infections | 1.931 (1.063–3.50) | 0.031 |
| Acquisition of infection (CABSI as reference) | 1.006 (0.633–0.399) | 0.053 |
| Any co-morbidities | 1.467 (1.017–2.114) | 0.040 |
| Referring from another hospital | 2.049 (1.411–2.975) | <0.001 |
