How should family spillover effects be measured in HTA?

A paper by Campbell et al. (2024) provides some guidance. The authors developed a series of recommendations based on literature review, expert interviews and an expert workshop in order to support consistent and transparent evaluation and use of validated family spillover effects in health technology assessments (HTA) and cost-effectiveness analyses (CEA). The expert panel consisted of 2 patient advocates, 2 health economists, 2 outcomes researchers, 1 health policy expert, and 1 payer.

Based on this approach, the experts settled on 15 recommendations with medium to high consensus. The recommendations were made for 3 different stakeholder groups: (i) HTA agencies, (ii) researchers who develop models, and (iii) researchers who collect and analyze data on family spillovers. These recommendations are listed in the table below.
