Key result
Risk-standardized 30-day and 1-year all-cause mortality after TAVR showed no significant interhospital variation among 10 hospitals, with all hospitals performing as expected.
Why the study?
Despite the rapid dissemination of TAVR, there is a paucity of reliable case-mix adjustment models for hospital profiling post-TAVR.
Population
2129 TAVR procedures performed at 10 hospitals in Ontario, Canada
Comparison
Hospital performance classified as worse than expected, better than expected, or as expected
Design
Population-based study
Follow-up
1 year

TAVR mortality consistency across hospitals may redirect quality efforts; leaves open assessment of other metrics like complications or readmissions.
Observational (n=2,129)
Yes
There was no significant interhospital variation in risk-standardized mortality rates after TAVR in Ontario, suggesting quality improvement efforts should focus on aspects other than mortality variation.
Elbaz‐Greener et al. (2018) conducted an observational in Transcatheter aortic valve replacement (TAVR) (n=2,129). TAVR hospital performance vs. Provincial average was evaluated on 30-day and 1-year risk-standardized all-cause mortality rates (RSMRs). Risk-standardized 30-day and 1-year all-cause mortality after TAVR showed no significant interhospital variation among 10 hospitals, with all hospitals performing as expected.
