PRBC Transfusion Is Significantly Associated With Longer Duration of Mechanical Ventilation and Length of Intensive Care Unit Stay
| Overall | No Transfusion | One Transfusion | >1 Transfusion | P Value | P Value 1 vs >1 PRBC Transfusion (Adjusted) | P Value 0 vs 1 PRBC Transfusion (Adjusted) | |
|---|---|---|---|---|---|---|---|
| (N=396) | (N=73) | (N=111) | (N=212) | (Unadjusted) | |||
| Length of mechanical ventilation, d | 6 (3, 11) | 3 (1, 5) | 4 (3, 6) | 9 (5, 16) | <0.0001 | <0.0001 | 0.43 |
| Length of intensive care unit stay | 17 (11, 31) | 9 (6, 19) | 13 (8, 25) | 21 (13, 38) | <0.0001 | <0.0001 | 0.059 |
| Infection (wound infection, sepsis) | 34 (9%) | 5 (7%) | 9 (8%) | 20 (9%) | 0.79 | 1 | 1 |
| Death | 27 (7%) | 2 (3%) | 7 (6%) | 18 (8%) | 0.22 | 1 | 0.65 |
When comparing between strata, those receiving >1 transfusion during the study period had significantly longer intensive care unit length of stay and duration of mechanical ventilation. PRBC indicates packed red blood cell.
