To me there is less of a difference than Adena Cohen indicates. Alot of health care delivery is not given out by official health provider. Self-care say for minor illness, or following a healthy diet or exercise plan I would consider health care. Also, Adena notes the provider and the patient can make choices but eventually the provider gives the health care. True, but the provider does depend on the client to participate by, for example, taking the meds prescribed, etc.
Patient compliance is an important part of good health care.
If patients feel like partners with providers they will communicate better, understand the issues better and be more likely to follow recommendations they had a hand in developing.
