Five minutes with the authors of chapter 4: Best Buys

Category : Others

We had a quick catch up with Tazeem Bhatia[1] from Global Public health and Ryota Nakamura[2] from Hitotsubashi Institute for Advanced Study, co-authors of Chapter 4 titled Best Buys to get a better understanding of what this chapter entails. Let’s learn more below!


Q : Can you please tell us in one sentence what your chapter is about? 


TB: The chapter demonstrates that context sensitivity is a crucial element of determining whether an intervention is cost effective and therefore a best buy in a local setting


RN: The chapter is about practical barriers in implementing a Best Buy in Non-Communicable Disease (NCD) prevention.  


Q : Ok. So can you tell uswhat the differences between best buys and contestable buys are? And how do you differentiate between them? 


TB: A Best Buy has evidence of cost-effectiveness in that setting, rather than a Contestable Buy that has an aspiration or assumption of cost effectiveness


RN: A Best Buy is demonstrated by local evidence; a Contestable Buys is based largely on aspirations only.


Q : Finally, why should readers not miss reading this chapter? 


TB: This chapter uses real world experiences to describe why evidence of cost-effectiveness from elsewhere is not sufficient information to prioritise an intervention


RN: WHOs Best Buys list is great, but policymakers should not adopt it blindly. The chapter explains why.


The NCD Prevention: Best Buys, Wasted Buys and Contestable Buys book will be launched on 12th December 2019 (UHC Day). To find out more about the project, please visit and stay tuned for more insights with book authors, editors, and reviewers in the coming weeks.
