Is it the Right Topic? An Overlooked Stage in the Institutionalization of Health Technology Assessment

Producing a Health Technology Assessment (HTA) is resource intensive, therefore, an explicit process for Topic Identification, Selection, and Prioritization (TISP) can optimize the use of limited resources to those HTA topics of national importance. TISP does not have to be complicated, however, a formalized process facilitates HTA recommendations that better align with local priorities. The comprehensiveness of TISP processes varies according to countries' needs and to the types of decisions HTA supports. There may be many relevant considerations for TISP, such as the resources available for allocation within the health system, the number of dedicated personnel to complete HTA, and the number of stakeholders and institutions involved in the decision-making process. In countries where HTA-supported decision-making is well-established, the process for TISP is usually formalized. In settings where HTA is emerging, relatively new, or where there may not be the necessary supporting institutional mechanisms, there is limited normative guidance on how to implement TISP. We argue that developing a clear process for TISP is key when institutionalizing HTA. Moreover, insights and experiences from more formalized HTA systems can provide valuable lessons. In this commentary we discuss three institutional aspects that we believe are vital to TISP: 1) Begin topic selection with a clear link to health system feasibility, 2) Ensure legitimacy and impact through transparent TISP processes, and 3) Include the public from the start to embed patient and public engagement throughout HTA.
