A systematic review of health economic evaluation quality assessment instruments for medical devices

Health economic evaluations are important for healthcare resource allocation. Reviews of health economic evaluations for medical devices have highlighted concerns about the quality of these studies. The complexity of medical devices, including learning curve effects, organizational impact, dynamic pricing, low evidence, and incremental innovation presents unique challenges compared with pharmaceuticals. To support developing a methodological quality assessment instrument for medical device economic evaluations, we conducted a systematic review to identify and evaluate existing economic evaluation quality assessment instruments for suitability in medical device evaluations.

A comprehensive search of databases (MEDLINE, EMBASE, EconLit, CINAHL, and Web of Science) and grey literature was conducted. Two reviewers screened titles and abstracts. Full-text, peer-reviewed primary studies introducing original instruments were included. Only methodological quality assessment instruments were considered for data extraction. Each item was assessed for its suitability in evaluating medical device economic evaluations and inclusion of medical device-specific features.

The search identified 4203 citations and 77 grey literature sources. Fifteen results underwent full-text assessment, with five relevant instruments identified. A previous systematic review identified 10 additional instruments, which we also considered. Of these 25 articles, 13 were included in the review. These instruments lack specificity for medical devices, particularly in addressing features like learning curve effects, organizational impact, and incremental innovation. Instruments should include items specific to these unique characteristics.

Existing instruments contain general items related to health economic evaluation studies, highlighting the need for an instrument specifically tailored to evaluate the methodological quality of medical device economic evaluation studies.
