Stroke center status skews TAVR stroke rates in national registry

An analysis of 525,919 TAVR cases from 800 sites in the STS/ACC Transcatheter Valve Therapy Registry (2016-2023) found that hospital Comprehensive Stroke Center designation and participation in TAVR trials were independent predictors of reported in-hospital and disabling stroke rates, but not of other outcomes used as falsification end points, the study reported. The authors state that correcting for CSC status changed estimated 30-day composite performance for 8 of 153 CSC hospitals, and conclude that further work is needed to address potential ascertainment bias in public reporting of stroke after TAVR.

Most relevant for: Hospitals and clinicians involved in TAVR program performance reporting and public quality metrics, particularly those at Comprehensive Stroke Center-designated institutions.
