Their attempt draws again the attention to the importance of approaching real word implementation issues from a theoretical perspective. It also highlights the importance of fidelity assessment within process evaluation of health programs. In this comment we argue that theoretical developments in the field of implementation science in global health would benefit from an accurate understanding of existing conceptual frameworks as well as from taking into account all contemporary contributions. specialized Implementation research Implementation fidelity Conceptual framework Performance-based financing MALAWI 056 7 art. 100305 [3 ] 2019 2352-8273 https://www.documentation.ird.fr/hor/fdi:010076536 10.1016/j.ssmph.2018.10.005 2352-8273 [F B010076536] https://www.documentation.ird.fr/hor/fdi:010076536 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers19-08/010076536.pdf IRD - Base Horizon / Pleins textes 2019-09-19 2025-02-24 fdi:010076536 fre
