Differences in Outcome for Medical and Source Control Groups
| Outcome Measures | Total Cohort (n = 205) | Medical Group (n = 111) | Source Control Group (n = 94) | p |
|---|---|---|---|---|
| 30-d mortality (n [%]), mean (sd) | 69 (33.7) | 39 (35.14) | 30 (31.9) | 0.63 |
| ICU mortality (n %), mean (sd) | 45 (21.0) | 26 (23.4) | 17 (18.1) | 0.32 |
| Hospital LOS (mean ± sd)a | 14.2 (13.0) | 11.5 (10.2) | 17.4 (15.2) | < 0.01 |
| ICU LOS (mean ± sd)b | 6.4 (6.4) | 5.2 (5.6) | 7.7 (6.9) | < 0.01 |
| Days on mechanical ventilation (mean ± sd) | 5.8 (6.1) | 5.0 (4.5) | 6.8 (7.5) | 0.13 |
| Acute kidney injury needing renal replacement therapy (n [%]) | 40 (19.5) | 22 (19.8) | 18 (19.2) | 0.90 |
LOS = length of stay.
aHospital LOS for the intervention group vs medical group remained statistically significant in the model (parameter estimate = 5.04 d [se = 1.68]; p = 0.0031) adjusting for age and body mass index (BMI).
bICU LOS for the intervention group vs medical group remained statistically significant in the model (parameter estimate = 2.25 d [se = 0.85], p = 0.0088) adjusting for age and BMI.
