Trends and predictors of Readmissions after Left ventricular assist device

Abstract

ABSTRACTBackgroundImpella Left ventricular assist device (LVAD) is used for hemodynamic support during high risk coronary interventions and in patients with cardiogenic shock. Data on percutaneous Impella ventricular assist device related 30-day readmissions are not well studiedMethodsThe Healthcare Cost and Utilization Project National Readmission Database was used to identify index hospitalization with Impella placement in patients ≥18 years old. Multivariate logistic regression analyses were used to examine factors associated with risk of 30-day readmissions. ResultsWe evaluated 5,941 hospitalized patients who survived to discharge after index hospitalization from January through November 2018 and analyzed readmissions over 30 days after discharge. A total of 1,418 patients (24%) were readmitted within 30 days, the most common reasons for readmission included acute myocardial infarction (27%) and heart failure (15%).Conclusions30-day readmissions were associated with a significant increase in healthcare costs. The majority of readmissions were secondary toacute myocardial infarction and heart failure. Ongoing efforts are required to recognize and reduce potentially preventable readmissions.
