This document outlines the development of a new Public Health Services and Systems Research (PHSSR) research agenda. It discusses conducting a systematic review of existing PHSSR research agendas and literature in key areas. A series of webinars were held to draft the research agenda and identify priority research questions. The draft agenda will be vetted at several conferences and online to gain feedback from researchers and practitioners. The finalized agenda will be disseminated widely to help guide future PHSSR.
