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.
