Amidst competing priorities for allocating finite health resources, using evidence-informed priority setting is a valuable tool for achieving population-level health goals. The paper by Baltussen et al comprehensively reports on the development of practical guidance for evidence-informed deliberative processes (EDPs) which will help with sustainability of programs aimed at universal health coverage (UHC). The authors' experience with the Joint Learning Network for UHC's (JLN) peer-to-peer learning platform on evidence-informed priority setting offers insights on the practical challenges faced by countries in health benefits package (HBP) design, especially to draw in actors to advocate for the priorities and values across the health system. Lessons harvested from JLN countries that have established such advisory committees can provide practical insights for countries in earlier stages of establishing a systematic process for HBP design. Peer-to-peer learning modalities among countries offer viable and effective approaches to institutionalizing EDPs and systematic priority setting.
