Most people are familiar with the term Caregiver as defined by Merriam-Webster. The Caregiver term is starting to change to Care Partners. Care Partners is a team which consists of the the patient and the support person. This team develops an environment that provides the best quality of life for each person. There could be multiple Care Partners i.e. Spouse, family members, or even close friends.
"Definition of caregiver: a person who provides direct care (as for children, elderly people, or the chronically ill)."
The Pulmonary Fibrosis Foundation 2019 Summit Presentation: "Caregiver" goes into a discussion on Caregiver vs Care Partner. The American Lung Association, Lungs & You, and Pulmonary Fibrosis MD articles address what the PF patient and their supporter could do for each other. This supports the idea that a Caregiver is really a Care Partner.
