Abstract

Background: Patients undergoing transcatheter aortic valve replacement (TAVR) are likely to be discharged to a location other than home. We aimed to assess the association between discharge disposition after TAVR and patient survival at 1 year.

Methods: Patients admitted from home and survived till discharge after TAVR were divided into two groups based on discharge disposition (home discharge vs. non-home discharge). Pre-operative factors predicting the odds of not being discharged home were identified by using multivariable logistic regression analysis. Study patients were matched one-to-one via a propensity scoring method. Differences in procedural outcomes were compared. Survival of both unmatched and matched pairs was evaluated by using the Kaplan-Meier method with the Kleine-Moesch-Berger stratified log-rank test.

Results: Out of 1,160 TAVR patients, 851 were admitted from home and survived till discharge. The incidence non-home discharge was 19% (n = 159). Factors that were significantly associated with non-home discharge were older age, non-transfemoral approach, female sex, frailty status, history of chronic lung disease, pacemaker placement and insulin-dependent diabetes mellitus. One-to-one propensity score matching resulted in 141 patient pairs with similar age, operative risk, frailty and functional status. At 1-year follow-up, all-cause mortality rates were significantly higher in the non-home group than their home counterparts (18% vs. 3%, P = 0.006; stratified log rank test: P = 0.006).

Conclusions: A considerable number of TAVR patients are discharged to a location other than home after the procedure. Not being discharged home after TAVR is associated with a high mortality risk at 1 year.
