    Abstract:
    Despite decreasing morbidity and mortality in left ventricular assist device (LVAD) recipients, readmission after implantation remains a major problem. Our aim was to investigate the trends and outcomes of 90 and 180 day readmission in this population. The National Readmission Database from 2012 to 2017 was queried to identify LVAD recipients. A total of 5,907 adults (90 day readmissions) and 3,653 adults (180 day readmissions) who survived LVAD implantation during the index admission were included in our analysis. Readmissions occurred in 45.6% and 65.1% by 90 and 180 days, respectively, with most readmissions occurring within the first 20 days. During the study period, mortality at index admission and readmission rate after discharge from index admission remained stable, whereas mortality during the readmission declined overtime both at 90 and 180 days. Heart failure was the most common cause for readmission (both 90 and 180 days), while its incidence also increased over the years. Among the reasons for readmission, intracranial bleeding, ischemic stroke, and device thrombosis were associated with highest mortality and gastrointestinal bleeding with the lowest. Intracranial bleeding, device thrombosis, and device infection were associated with longer length of stay. Multivariate logistic regression models identified gastrointestinal bleeding, length of stay during index admission, and end-stage renal disease requiring hemodialysis as risk factors of readmissions. Our study has unveiled several important factors associated with readmission and mortality. Approaches to identify and prevent readmissions early after LVAD implantation by addressing these factors may lead to lower morbidity, healthcare cost related to readmission, and improved quality of life.
