Clinical Significance of Early Hospital Readmission in Continuous-Flow Left Ventricular Assist Device Patients

Data on the clinical significance of early hospital readmission within 90 days following left ventricular assist device (LVAD) implantation in patients with continuous-flow LVAD are limited. We aimed to assess the incidence, predictors, and outcomes of 90-day readmission in LVAD patients. Hospital readmission or death was assessed within 90 days after hospital discharge in 177 patients with HeartMate II LVADs implanted between May 2008 and June 2014. Predictors of early readmission and risk of death were evaluated using multivariable Cox models following adjustment for clinical covariates. Hospital readmission or death rate was 37% within 90 days. Age at implantation (hazard ratio [HR] = 1.03 per 1 year increase, p = 0.016), diabetes (HR = 2.19, p = 0.031) and smoking at baseline (HR = 2.06, p = 0.034) predicted early hospital readmission, while a higher baseline body mass index was found to be protective (HR = 0.92 per each unit increase in body mass index, p = 0.003). One-year all-cause mortality was 19% in patients with early hospital readmission as compared to 1% with no early hospital readmission (HR 15.50, p = 0.01). One-year mortality was 35% in patients with 2 or more readmissions compared to 10% mortality in patients with one readmission and 1% mortality in patients with no readmissions (p
