The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Acad- emy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineer- ing programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is presi- dent of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Insti- tute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sci- ences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Coun- cil is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Abstract Due in large part to the widespread use of highly active antiretroviral therapy, HIV has become a chronic disease. Persons whose HIV is managed adequately to maintain their viral load at a low or undetectable level have better health status, live longer, and are less infectious to others. Effective use of antiretroviral therapy (ART) and viral suppression require uninter- rupted care from an HIV knowledgeable health care provider, uninterrupted access to an adequate selection of anti-HIV medications, and a patient whose mental health and life situation do not interfere with receipt of care and adherence to medication regimens. In addition, management of other medical conditions is needed to avoid the irony of patients who receive costly treatment for HIV becoming disabled or dying from preventable complications of conditions such as diabetes. Similarly, providers caring for other health needs of HIV-infected individuals should be attuned to the need of patients to receive appropriate HIV care as well. The committee identified a number of barriers to adequate HIV treat- ment and its demonstrated benefits for patients and public health that arise from various sources. Patients may lack access to a provider with HIV-specific expertise or may experience interruptions in care for patient- based or systemic reasons. Even patients with apparently adequate access to publicly funded health care (e.g., Veterans Affairs, Medicaid, Medicare) and/or private health insurance coverage may encounter both financial (e.g., caps, co-pays, formulary limitations, waiting lists) and other barriers (e.g., inability to locate a provider, distance to clinics) to receipt of care. Moreover, daily life for a sizeable percentage of HIV-positive persons is very challenging for reasons such as stigma, poverty, mental health problems, xv

xvi ABSTRACT substance abuse, incarceration, undocumented immigrant status, housing instability, and other afflictions and conditions that interfere with chronic disease management. The committee recognizes that successful manage- ment of patients experiencing multiple, interacting conditions requires, in addition to appropriate medical care, the availability of comprehensive and flexible services, such as transportation, medication adherence programs, and dietary and housing assistance, which generally are not reimbursable by health care financing programs, with the notable exception of the Ryan White program. The committee also found that there are numerous obstacles to main- taining an acceptable standard of care, including low reimbursement rates, shortages of health and allied health providers, unstable funding, unclear or inconsistent eligibility and reimbursement criteria, and burdensome reporting requirements. These problems arise from and are aggravated by the lack of integration of state and federal government programs address- ing the needs of HIV-infected individuals and the intertwined medical and social problems often associated with HIV. Problems in providing HIV care, such as low reimbursement rates and minimal exposure to HIV care during training, may lead health and allied health providers to avoid entering the field of HIV care, generating concerns about a future shortage of providers as the first generation of HIV providers retire from practice. The committee ascertained that the policy response to HIV suffers from the lack of integration of federal and state programs, as well as from gaps in important data on HIV patients and their care. Greater coordination and integration of federal and state programs should help to consolidate, and therefore reduce the burden of, reporting requirements. Along with careful consideration of the data sets to be reported, program coordination and integration also could facilitate and improve the acquisition of data needed to evaluate the quality of care patients receive and the cost-effectiveness of the various programs. Another area of HIV policy concerns the CD4 and/or viral load levels at which ART should be initiated and those at which insurance companies or other payors will cover treatment for HIV-infected individuals. Currently U.S. Department of Health and Human Services guidelines and Interna- tional AIDS Society-USA HIV treatment guidelines recommend that ART be initiated in patients with CD4 counts at or below 500. There is less agreement regarding initiation of therapy in asymptomatic patients with counts above 500. The committee recognizes the importance of identifying a set of definitive treatment guidelines to inform policy on the initiation and payor coverage of ART. Such treatment guidelines would be re-evaluated frequently and updated as needed to reflect current knowledge in HIV medicine.

xvii ABSTRACT Although the Patient Protection and Affordable Care Act will improve access to HIV care in some respects (e.g., Medicaid will become available without categorical restrictions), it may aggravate the situation in other ways (e.g., funding for the Ryan White program, the primary source of funding for flexible services and safety-net providers, may be reduced or cut). Policies in the areas of housing, corrections, immigration, mental health services, and substance abuse all affect the care of HIV-infected persons and would benefit from increased coordination among and transi- tions between various programs and funding mechanisms. Many of these policy concerns pertain to care for other chronic health conditions as well (e.g., diabetes, hypertension, kidney disease, etc.). But HIV’s communicable nature and the very high personal and financial costs associated with each new infection add significant public health and economic components to the considerations of social justice that necessarily accompany policies that affect the provision of HIV care.
