A systematic review of health economic evaluation in orthotics and prosthetics: Part 2—orthotics

Background: Health economic evaluations (HEEs) in orthotics are in their infancy. Identification of evidence gaps and method design issues will inform the design of future HEEs that advance knowledge and contributes to policy and investment decisions. Objectives: The aim of this systematic review was to critically appraise the existing orthotic/prosthetic health economic evaluation literature and therefore determine evidence gaps, critical method design issues, and the extent to which the literature informs orthotic policy and investment decisions. Study Design: Systematic review. Methods: A range of databases were searched using intervention- and HEE-related terms. The Consolidated Health Economic Checklist—Extended and the Checklist for Health Economic Evaluation Reporting Standards were used to identify issues with method design and reporting. Results: Nine orthotic HEEs were narrowly focused on the cost-effectiveness of low-cost orthotic devices (eg, ankle orthoses for ankle sprains). Method design (eg, cost identification and valuation) and reporting issues (eg, lack of detail about the study population) limited the extent to which this literature can inform policy and investment decisions. Conclusions: HEEs comparing a wider variety of interventions are required, particularly for commonly used orthoses (eg, ankle-foot orthoses) and clinical presentations (eg, post-stroke). There are opportunities to strengthen future orthotic HEEs by adopting method design features (eg, microcosting and sensitivity analyses) as recommended by HEE appraisal and reporting tools.
