Linking the TVT Registry to Medicare Advantage and Fee-for-Service Claims: Feasibility, Accuracy, and Implications for Real-World Surveillance Infrastructure

Circ Cardiovasc IntervPublished

  • Registry linkage study
  • linked using indirect identifiers to Medicare Advantage (MA) and fee-for-service (FFS) claims

Authors' conclusion

Inclusion of MA claims in Medicare linkage to TAVR or mitral transcatheter edge-to-edge repair increased cohort size, enhanced subgroup representation, and maintained linkage rates despite declining FFS enrollment. These findings support incorporation of MA data into real-world surveillance, clinical evidence generation, and quality initiatives.
