An institutional ethnographic analysis of public and patient engagement activities at a national health technology assessment agency.

HTA organizations can learn from this study by reflecting on the challenges described and the recommendations offered to address them. We suggest solidifying CADTH's commitment to PPE with clear agency-wide roles and direction, values, and outcomes, a comprehensive framework, and policy and procedures. An acknowledgment of diverse epistemic traditions, as well as leadership and expertise in PPE, will strengthen CADTH's PPE activities and sustain its leadership position in the HTA field.
