Physicians largely work alone. When the examination room door closes, each physician accepts responsibility for the care of the patient in front of him or her. It is hard and important work. Traditional values (the sanctity of the patient-physician relationship), training (with emphasis on individual responsibility), practice (referral to a specific individual), and payment (fee-for-service) all reinforce this professional model and the notion that physicians influence health primarily through the individual patient-physician encounter.
