Learn practical lessons from the OECD review on designing pay-for-performance and impact evaluations. Explore quantitative, experimental, and non-experimental methodologies, including randomized control trials. Understand the importance of internal and external validity while considering the timeline, civil society involvement, and implementation challenges. Discover how to create impact models, translate them into measurable indicators, and plan resources effectively for successful evaluations. Emphasizing the need for qualitative assessments, this review sheds light on evaluation practices in OECD countries, highlighting areas for improvement based on examples like the US Premier Hospital scheme and QOF.

Pay for performance and impact evaluation design Practicallessonsfrom OECD review Y-Ling Chi, OECD
Methods available • Quantitative methods • Experimental methods Golden standard • Non-experimental methodology • Quasi experimental methods • Qualitative methods
Non-experimental/Quasi experimental • Quasi-experimental: Interrupted times series, regression discontinuity and score matching • Non experimental: before/after intervention or treatment/control afterwards
Experimental methods = Randomized Control Trials (RCTs) • Easy to understand • InternalValidity • ExternalValidity BUT • Timeline (very long) • Strong civil society (hard to comply) • Hard to implement (need to have experts) • Expensive
Treatment Treatment INTERVENTION GROUP control control t -0 intervention t +1 Evaluation: difference between control and treatment // difference in t-0 and t+1
How to understand Impact Evaluation? • Design a proper impact model • Translate impact model into quantifiable indicators • Think about the design model • Timing has to articulate within the implementation process • Plan resources ahead (staff, implementation, analysis etc.) • Once you finish, need good qualitative evaluation
Review from OECD countries • OECD countries don’t do well in terms of evaluation US Premier Hospitalschemeexample shows thatevaluationis not central once the prorgam has been implemented. QOF shows thatdespite the yearlycost -1 billion pounds-, investment for evaluationis marginal but not evenwellperformed.
