Trends, Predictors and In-Hospital Outcomes of the Next Day Discharge Approach After Transcatheter Mitral Valve Repair

Early discharge strategies are associated with lower cost and resource utilization during hospitalization, as such we sought to evaluate trends, predictors and outcomes of the next day discharge (NDD) approach after transcatheter mitral valve repair (TMVR) procedures with the MitraClip device. The National Inpatient Sample (NIS) was queried between 2013 and 2018 for patients undergoing TMVR using the International Classification of Diseases (ICD) 9 procedure code ‘3597′ and ICD-10 procedure code ‘02UG3JZ’. Patients undergoing TMVR were stratified into two groups, determined by hospital length of stay (LOS) [≤1 day, NDD versus >1-day, non-NDD]. Overall, 22,035 patients underwent TMVR with 35.7% (n  = 7,870) belonging to the NDD group (mean age 78.1 ± 9.7 years, women 45%). From 2013 to 2018, the proportion of patients being discharged using the NDD approach trended upward from 18.3% to 46.0%. Amongst demographic and social factors, female sex, black race, and low median household income were predictive of non-NDD (p
