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 https://www.buyitbestncd.health/ and stay tuned for more insights with book authors, editors, and reviewers in the coming weeks.
