ABSTRACT
We review the state of evaluation within outcome-based commissioning in the United Kingdom. This is the first review to include empirical evaluations of both PbR and SIB programmes. We find a paucity of evaluation and that the quality of evaluations is not high. Moreover, studies tend to conflate the outcomes-based commissioning mechanism with the intervention or services that are funded, and are unable to assess the contribution of these separate elements to impact. Our review also highlights the challenges faced by evaluators in measuring social outcomes. We suggest ways to address these challenges.

4. Shortly after the review was completed the final impact evaluation for the Peterborough SIB was published (Anders and Dorsett Citation2017). It is not part of the review.
6. Shortly after the review was completed the final impact evaluation for the Peterborough SIB was published (Anders and Dorsett Citation2017). It is referred to later in this paper, but was not part of the review.
