Transitional care has been defined as a set of actions designed to ensure the coordination and continuity of health care as patients transfer between different locations or different levels of care in the same location. Transitional care, which primarily concerns the relatively brief time interval that begins with preparing a patient to leave one setting and concludes when the patient is received in the next setting, poses challenges that distinguish it from other types of care. Many transitions are unplanned, result from unanticipated medical problems, occur in "real time" during nights and on weekends, involve clinicians who may not have an ongoing relationship with the patient, and happen so quickly that formal and informal support mechanisms cannot respond in a timely manner. This article describes the challenges involved in and potential solutions for improving the quality of transitional care.

The patient-centered medical home could well be a transformative innovation-for some practices now, but for many others only in the long run.by Robert A. Berenson, Terry Hammons, David N. Gans, Stephen Zuckerman, Katie Merrell, William S. Underwood, and Aimee F. Williams ABSTRACT: The "patient-centered medical home" has been promoted as an enhanced model of primary care. Based on a literature review and interviews with practicing physicians, we find that medical home advocates and physicians have somewhat different, although not necessarily inconsistent, expectations of what the medical home should accomplish-from greater responsiveness to the needs of all patients to increased focus on care management for patients with chronic conditions. As the medical home concept is further developed, it will be important to not overemphasize redesign of practices at the expense of patient-centered care, which is the hallmark of excellent primary care. T h e pat i e n t-c e n t e r e d m e d i c a l h o m e (PCMH) is the newest idea being promoted as a transformative health system innovation. Proponents believe that it will improve the quality of and patients' experiences with care and alter the trajectory of inflationary health care spending. 1 The PCMH has been proposed by four primary care physician specialty societies; has been endorsed by a range of purchaser, labor, and consumer organizations, including IBM, Merck and Company, the ERISA Industry Committee, and AARP; and is being tested in demonstrations by major public and private health plans, including Medicare, various Blue Cross and Blue Shield plans, UnitedHealthcare, and Aetna. 2 The medical P r a c t i c e R e d e s i g n H E A LT H A F F A I R S~Vo l u m e 2 7, N u m b e r 5 1 2 1 9

A large, widening gap exists between the incomes of primary care physicians and those of many specialists. This disparity is important because noncompetitive primary care incomes discourage medical school graduates from choosing primary care careers. The Resource-Based Relative Value Scale, designed to reduce the inequality between fees for office visits and payment for procedures, failed to prevent the widening primary care-specialty income gap for 4 reasons: 1) The volume of diagnostic and imaging procedures has increased far more rapidly than the volume of office visits, which benefits specialists who perform those procedures; 2) the process of updating fees every 5 years is heavily influenced by the Relative Value Scale Update Committee, which is composed mainly of specialists; 3) Medicare's formula for controlling physician payments penalizes primary care physicians; and 4) private insurers tend to pay for procedures, but not for office visits, at higher levels than those paid by Medicare. Payment reform is essential to guarantee a healthy primary care base to the U.S. health care system.
