Abstract

Background: This study evaluates the Area Deprivation Index (ADI) as a novel prognostic metric of socioeconomic status for patients with a left ventricular assist device. Methods and Results: A retrospective analysis of patients with a left ventricular assist device at a high-volume institution from 2007 to 2018 was conducted. Socioeconomic status was determined using the ADI, a multifactorial neighborhood-based metric where higher ADI denotes worse socioeconomic status. Patients were stratified into 4 ADI cohorts. Long-term survival was compared with multivariate analysis. Of the 380 patients stratified by ADI, 35 were in the 10th percentile or lower, 218 were in the 11th–50th percentile, 104 were in the 51st–89th percentile, and 23 were in the 90th percentile or higher. Baseline characteristics were comparable. On multivariate analysis, being male (hazard ratio [HR], 0.14; P = .01), bridge-to-transplant (HR, 0.14; P = .03), and not requiring biventricular support (HR, 0.02; P < .01) were protective, whereas chronic kidney disease (HR, 9.07; P < .01) and an elevated total bilirubin (HR, 3.56; P = .02) were harmful. The ADI as a continuous variable did not affect survival; however, categorically, a higher ADI was protective (ADI 90–100: HR, 0.07; P = .04). Conclusions: Socioeconomically disadvantaged patients had noninferior outcomes given appropriate pre-implant optimization and workup.
