'Power plays plus push': experts' insights into the development and implementation of active tuberculosis case-finding policies globally, a qualitative study.

We provide new insights into ACF policy processes globally, particularly regarding facilitators for and barriers to ACF policy development, evidence need and use, and donor organisations' influence. According to expert participants, national and global ACF policy development and implementation can be improved by broadening stakeholder engagement. Meanwhile, using diverse evidence to inform ACF policy development and implementation could mitigate the 'power plays plus push' that might otherwise disrupt and mislead these policy processes.
