Design and Features of Pricing and Payment Schemes for Health Technologies: A Scoping Review and a Proposal for a Flexible Need-Driven Classification.

Background and objective: In a context of growing clinical and financial uncertainty, pricing and payment schemes can act as possible solutions to the problems of affordability and access to health technologies. However, a comprehensive categorization of the available schemes to help decision makers tackle these challenges is lacking. This work aims at mapping existing types of pricing and payment schemes, and proposes a new approach for their classification, in order to help decision makers and other stakeholders select the best type of scheme to meet their needs.

Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR)-compliant scoping literature review was performed between 2010 and 2023 in three databases (PubMed, Web of Science, Scopus). The search strategy was developed around two groups of keywords, "pricing/payment schemes" and "scheme innovativeness". Eligible studies were those illustrating the unique design and features of each scheme type, which were extracted by two independent reviewers, and synthesized using a narrative format, including a detailed tabular description of each type of scheme.

Results: A total of 70 unique types of pricing and payment schemes were identified. Around one third (33%) was only specified in principle, while two thirds (67%) had been implemented in practice. About half of the scheme types were proposed for drugs (34/70, 49%), and the vast majority were not designed for a specific therapeutic area (55/70, 79%). Each scheme type was categorized based on distinctive characteristics: the objectives, the outcome component, the timing/modalities of payments, and the evidence collection requirements.

Conclusions: Instead of trying to fit the retrieved schemes into a rigid taxonomy, we propose a new approach that suggests a flexible need-driven use of the available scheme types, driven primarily by the specific objective that one might have, and allows leveraging of the other key characteristics of each type of scheme.
