In 2020, the Swedish regions cemented a national managed-introduction project for medical devices, to ensure equal, cost-effective, and appropriate use. Health technology assessment (HTA) is an important component of the project. Swedish national health registers have world-class coverage and completeness but may lack information enabling adequate evaluation of medical devices. This study reviews the current situation and ongoing initiatives. Additionally, the potential for medical device health economics and outcomes research (HEOR) using Swedish registers is assessed.

A review of Swedish national health registers was undertaken, focusing on available data, and contextualized for the purpose of HEOR for medical devices. Additionally, the review included an evaluation of the Swedish reimbursement authority's (The Dental and Pharmaceutical Benefits Agency, TLV) ongoing initiatives to improve the potential to follow-up the impact of the technologies they assess and develop value-based pricing schemes.

Five registers were deemed the most relevant national health registers for device research. They include high-quality longitudinal data and are linkable on a per-patient basis. For devices, main limitations include limited data on specialized outpatient care, lags in updating certain registers, lack of laboratory data, and challenges in identifying the specific device used. Reports indicate that certain limitations are being addressed, including pilot-studies investigating the opportunity for automated reporting of data from regional systems, and app-collected patient-reported health data.

Swedish registers provide comprehensive sources for HEOR studies, but limitations related to the assessment of medical device impact remain. As is common with register data reporting grouped diagnoses and interventions, specific devices are not directly identifiable in the national health registers. For some devices, this might be addressable through linkage with other data-sources. Swedish authorities are undertaking several initiatives that will likely improve the potential for HTA and follow-up of medical devices using national health register data.
