ABSTRACT
Background:
Perioperative blood transfusions are associated with increased morbidity and mortality. Each surgical specialty is associated with unique operative variables. Moreover, transfusion rates vary across specialty. This article seeks to elucidate variables both common and unique to surgical specialties. Materials andMethods:
This study was a retrospective review of 5344 patients from the prospectively maintained Veterans Affairs Surgical Quality Improvement Project at a single-level 1A tertiary Veterans Affairs Medical Center. Data collected included demographic information, preoperative clinical variables, postoperative outcomes, and perioperative transfusion (within 72 hours of procedure). Patients were stratified based on whether they received a transfusion. Univariate and multivariate analyses were performed. P values <.05 were significant.Results:
Of the 5344 patients included in the study, 153 required perioperative transfusion of at least one unit of packed red blood cells. Patients who underwent transfusion were more likely to be men, have an underlying bleeding disorder, and have more preoperative risk factors. Although unique risk factors were found within most specialties, there was no statistically significant difference in postoperative complications between surgical specialties. Patients requiring transfusion had higher rates of morbidity and mortality. Elevated preoperative hematocrit was significantly protective against requiring transfusion across most specialties.Conclusions:
Specialty-based differences in transfusion requirement may be due to the proportion of older and more frail patients, hospital transfusion thresholds, and surgical complexity. Hematocrit, however, could be an effective target for mitigating cost and morbidity associated with transfusion. Preoperative hematocrit optimization through B12, folate, iron dosing, and erythropoietin supplementation could be a useful strategy.
