Topic selection process in health technology assessment agencies around the world: a systematic review

Abstract

Abstract Objective The purpose of this study was to systematically review the process for topic selection by health technology assessment (HTA) agencies around the world to provide the knowledge base for the improvement of topic selection frameworks in HTA agencies. Methods A systematic search was conducted in PubMed and EMBASE to identify papers up to February 2019. Gray literature was identified by screening the Web sites of HTA agencies on the nonprofit member list of the International Network of Agencies for Health Technology Assessment (INAHTA). Data were extracted for each HTA agency and synthesized, with issues including general contextual information about each agency and the process of topic selection. Results Out of forty-nine nonprofit members of INAHTA, a total of seventeen HTA agencies with a framework for topic selection were identified from twenty-two included papers/documents. Multiple criteria were used for topic selection in all frameworks and agencies undertook multiple steps, which could include the specification of criteria for topic selection, identification of topics, short listing of potential topics, scoping of potential topics, scoring and ranking of potential topics, and deliberation and decision on final topics for HTA. Shortcomings were found in relation to methods of scoring and ranking as well as lack of monitoring and the evaluation of the process. Conclusions Our study provides insights into the current practice of topic selection in HTA agencies. Multiple criteria decision analysis methodology appears highly relevant to these processes. A consensus approach for the development of methods of topic selection would be valuable for the HTA community.
