By including stakeholders such as patients, family members, patient advocates, clinicians, and researchers, the authors were able to ensure that the model was relevant to patients and their clinicians. This stakeholder engagement also helped to ensure that the model was accurate and reliable. This article was authored by Denise H. Daudelin, Robin Routhazer, Manly Kwong, and others.
