Outcomes Based Agreements (OBAs) are financial arrangements that offer the opportunity to align payment to health outcomes in the real-world, and share the financial risk by providing long-term solutions that grant access to medicines, with reimbursement only when performance is achieved. OBAs are most likely to be useful when there is high uncertainty in the clinical data, but they are difficult to design and implement, and other financial options are usually preferred by payers. As a result, OBAs have been more the exception than the norm, and there is not a clear pattern that indicates if an OBA is likely to succeed in practice.

Through a retrospective OBA exercise with NHS Wales (Project IDEATE: Innovation in Data to Evolve Agreements That Enhance patient health outcomes), we have explored the circumstances under which an OBA might be most appealing to payers, and assessed implementation challenges and solutions, to propose a framework to evaluate the feasibility of a medicine for an OBA.

Along with mitigating some of the clinical uncertainties associated with a lack of mature data at the time of launch, an OBA must also consider other factors: the commercial viability of the agreement, the associated administrative burden, and its cost of implementation. Also, the Health System commitment to a Value-Based Healthcare agenda and, most importantly, its willingness to offer long-term sustainable solutions to optimise treatment, are key to support this approach.

Practical considerations include: how the relevant outcomes are going to be selected and tracked in the real-world, how the whole model is going to fit within the current procurement and finance infrastructures, and how industry works in collaboration with the Health System.

Insights from Project IDEATE will be used to explore how our OBA feasibility framework might be applied in the future.
