Multivariable Analysis of Factors Associated with the Time from Injury to First Infection
| Risk Factor | Multivariable Hazard Ratio (95 per cent CI) | P value |
|---|---|---|
| Any traumatic amputation | 1.64 (1.39 – 1.96) | <0.001 |
| Admission to the ICUa | ||
| LRMC only | 1.60 (1.12 – 2.30) | 0.011 |
| U.S. MTF ± LRMC | 2.73 (1.99 – 3.74) | <0.001 |
| PRBC transfusions within 24 hours of injuryb | ||
| ≥ 10 units | 1.64 (1.35 – 1.98) | <0.001 |
| Tranexamic acid use | 1.16 (0.98 – 1.38) | 0.078 |
CI – confidence interval; ICU – intensive care unit; LRMC – Landstuhl Regional Medical Center; MTFs – military treatment facilities; PRBC – packed red blood cells plus whole blood
a
The reference value was non-ICU.
b
The reference was transfusion of <10 units.
