Abstract
BACKGROUND: Since 2014, the Canadian Agency for Drugs and Technologies in Health (CADTH), which performs health technology assessments for all federal, provincial and territorial government drug programs (except Quebec's) and the pan-Canadian Pharmaceutical Alliance (pCPA), which conducts price negotiations with manufacturers for all government drug programs, have been aligning their processes.Entities:
