Concierge medicine offers a number of advantages for enrollees. Physicians spend more time with fewer patients in a more relaxed and comfortable environment, and can know the patients more personally and in greater detail. For patients, access to their physician at any time and (often) any place is an obvious benefit. However, retainer care does not provide the same rapid access to specialists, although concierge physicians indicate that they can facilitate such arrangements. In addition, the restricted practices of concierge medicine may expose those physicians to a lesser spectrum of disorders and limit their expertise. Those delivering retainer care counter that they have more time for educational activities. All agree that the service is an expense for patients and financially advantageous to providers.
