Abstract 14653: Periprocedural Transfusion is Associated With a Dramatic Increase in Morbidity and Mortality in Patients Undergoing Percutaneous Vascular Interventions: Insights From the The Bmc2-vic

Objective: Blood transfusions are common among patients undergoing vascular interventions. The impact of transfusion on patients undergoing vascular percutaneous interventions has been poorly defined. Methods: We examined data from a large multicenter (n=44 hospitals) quality improvement (QI) vascular interventional registry of all patients undergoing percutaneous vascular interventional (PVI) procedures for peripheral arterial disease (PAD) between 2010 and 2013. Multiple logistic regression modeling was used to identify predictors of, and effect of transfusion on outcomes. Results: Of the 18,127 patients enrolled in the registry, 4.1% received a blood transfusion. The median hemoglobin of those transfused was 7.7 mg/dL (IQR =7.2 - 8.4). Transfusion rates varied from 0 to 14% amongst the hospitals in the registry. From a logistic regression model for transfusion (C-statistic = 0.84 and Hosmer-Lemeshow P-value = 0.653), significant factors (all p<.01) that were independently associated with transfusion in...
