Left ventricular assist devices (LVADs) have emerged as an attractive option in patients with advance heart failure. Nationwide readmission database 2013 to 2014 was utilized to identify LVAD recipients using ICD-9 procedure code 37.66. The primary outcome was 90-day readmission. Readmission causes were identified using ICD-9 codes in primary diagnosis field. The secondary outcomes were LVAD associated with hospital complications. Hierarchic 2-level logistic models were used to evaluate study outcomes. We identified 4,693 LVAD recipients (mean age 57 years, 76.2% males). Of which 53.9% were readmitted in first 90 days of discharge. Cardiac causes (33.3%), bleeding (21.3%), and infections (12.4%) were leading etiologies of 90-day readmissions. Significant predictors (odds ratio, 95% confidence interval, p value) of readmission were disposition to nursing facilities (1.33, 1.09 to 1.63, p = 0.01) and longer length of stay (1.01, 1.00 to 1.01, p <0.01). Although private insurance (0.75, 0.66 to 0.86, p <0.01), and self-pay (0.58, 0.42 to 0.81, p <0.01) predicted lower readmissions. Cardiac complications (36.3%), major bleeding (29.8%), and postoperative infections (10.4%) were most common LVAD-related complications. In conclusion, high early readmission rate was observed among LVAD recipients with Cardiac complications, bleeding complications, and infections were driving force for major complications and most of readmissions.
