As a consequence, the medical staff represents the "power center" in hospital policy and decision-making, not the administration. Although usually there are in this situation four identifiable participants-- the physician, the hospital, the patient, and the payer (generally an insurance carrier or government)-- the physician makes the essential decisions for all of them.
