Over the years, the time of hospital stay following transcatheter aortic valve implantation (TAVI) had decreased, and next-day discharge was becoming more prevalent in clinical practice. For a study, researchers sought to use the 2015-2019 National Readmission Database of the United States to identify 196,618 patients who underwent TAVI (mean age 79.5 8.4 years, 45.0% female). About 245 patients (0.12%) were discharged on the same day as TAVI implantation [same-day discharge (SDD group)], while the rest of 196,373 patients were discharged on a different day (different-day discharge [DDD] group). A matched propensity score analysis was conducted. The unplanned readmission rate within 30 days after discharge did not differ substantially between the SDD and DDD groups (11.0% vs. 10.6%, hazard ratio 1.03, 95% CI 0.56 to 1.82, P=0.921). The SDD group had considerably lower hospitalization expenditures than the DDD group ($37,811±18,029 vs. $49,130±27,070, P<0.001). In conclusion, the 30-day readmission rate was comparable for patients discharged on the same day as TAVI and patients discharged later.
