However, no study has accounted for volume resuscitation with blood products as a confounder. We hypothesized that even when accounting for the amount of blood transfused, injury severity, and other patient factors, nephrectomy after HGRT would be associated with increased mortality and acute kidney injury (AKI). METHODS: We identified adult patients with HGRT (AAST grade III-V) in the American College of Surgeons TQIP database (2013-2017). Propensity scoring was used to adjust for the probability of nephrectomy. Patients undergoing nephrectomy were matched with replacement at a 1:5 ratio. Conditional logistic regression models with clustering were used (outcomes mortality and AKI). We adjusted for patient demographics, injury characteristics, shock, and units of packed red blood cells transfused in the first 24 hours. RESULTS: There were 14,470 patients included with HGRT, with 1,101 (7.6%) patients undergoing nephrectomy. Unadjusted mortality was 12.3% and 5.3% (p<0.001) in the nephrectomy and non-nephrectomy groups, respectively. In the nephrectomy patients, 7.9% experienced AKI during their hospital admission, compared to 2.2% of the non-nephrectomy patients (p<0.001). In our adjusted analysis, after propensity scoring and matching, there was no association between nephrectomy and higher mortality or AKI. In the adjusted analysis, increasing age, increasing injury severity score (ISS), decreasing Glasgow Coma Score (GCS), and higher volume of transfused blood were all associated with higher mortality. For AKI, independent predictors include increasing age, increasing ISS, penetrating injury, and blood transfusion. CONCLUSIONS: Using propensity scoring and adjusting for the volume of blood transfused in the first 24 hours, nephrectomy is not associated with increased mortality or AKI. This finding contradicts prior analyses where volume of blood was not accounted for. Despite these results, as a clinical principle, nephrectomy should be avoided when possible after HGRT.
