This chapter reviews the current status of services to prevent and manage chronic hepatitis B and chronic hepatitis C. The chapter ends with an assessment of gaps in existing services, including a description of some models for services and committee recommendations to improve viral hepatitis prevention and management and to fll research needs. Hepatitis B immunization is covered in Chapter 4 and so is not discussed in detail here. The recommendations offered by the committee here are presented in the context of the current health-care system in the United States. The com- mittee believes strongly that if the system changes as a result of health-care reform efforts, viral hepatitis services should have high priority in compo- nents of the reformed system that deal with prevention, chronic disease, and primary-care delivery. The committee’s recommendations regarding viral hepatitis services are summarized in Box 5-1.

The medical management component is included in the smallest percentage of plans (62.

The primary barrier to plan implementation was fnancial constraints on overall funding and staffng (96.

Their program Because physicians represent a cross-section of society, it directors need to be cognizant of the possibilities of such risky should be expected that the illnesses and disabilities that affect behaviour, which can in some cases lead to drug dependency the population at large will also occur among physicians. Lisa Graves’ 2008 article in Medical Teacher observes: “The wounded healer remains easily hidden in a profession that The sick physician implicitly, and at times actively, encourages a denial of illness. Physicians often feel it necessary to project a healthy image of In training, however, the wounded healer can be identifed and themselves to their patients and colleagues.

Physicians who wish to return to training or practice after acquiring a disability and can do so competently and safely, working with or without the use of functional aids and es- sentially on par with their fellow physicians, should be able to do so. They should be given every possible assistance on the part of program directors, colleagues and administrators to facilitate their return to training or practice. Their high levels of debt may be correlated with a received during residency, or the effects of poor spending lack of budgeting by residents.
