Abstract
Background
All health economics reviews on chronic and episodic migraine published to date underline the heterogeneity of results. Currently, the need for the generalizability of economic evaluations across different jurisdictions is considered a key issue to avoid unnecessary overlaps and to minimize the time to reimbursement decisions.
Objective
The aim of this study was to review the economic evaluations on the prophylaxis and treatments for migraine published in the previous 10 years (since 2009) and to perform a critical assessment of their generalizability.
Methods
We searched PubMed, EMBASE, and EconLit databases. Articles underwent a three-stage selection process. To assess the level of generalizability, we used the checklist implemented by Augustovski et al. Studies were classified as: (1) generalizable; (2) transferable; and (3) context specific.
Results
In total, 227 articles were identified after running the search string and 11 studies were included in our review. Overall, none of the studies was judged as generalizable and three were judged transferable according to the established criteria.
Conclusions
Our review suggests that no evidence on the economic value of either acute or prophylactic treatments against migraine is generalizable to different jurisdictions. However, the majority of studies reporting results about prophylactic treatments were found to be transferable.
