Diagnosis and treatment of depression in late life. Consensus statement update.

OBJECTIVE: To reexamine the conclusions of the 1991 National Institutes of Health Consensus Panel on Diagnosis and Treatment of Depression in Late Life in light of current scientific evidence. PARTICIPANTS: Participants included National Institutes of Health staff and experts drawn from the Planning Committee and presenters of the 1991 Consensus Development Conference. EVIDENCE: Participants summarized relevant data from the world scientific literature on the original questions posed for the conference. PROCESS: Participants reviewed the original consensus statement and identified areas for update. The list of issues was circulated to all participants and amended to reflect group agreement. Selected participants prepared first drafts of the consensus update for each issue. All drafts were read by all participants and were amended and edited to reflect group consensus. CONCLUSIONS: The review concluded that, although the initial consensus statement still holds, there is important new information in a number of areas. These areas include the onset and course of late-life depression; comorbidity and disability; sex and hormonal issues; newer medications, psychotherapies, and approaches to long-term treatment; impact of depression on health services and health care resource use; late-life depression as a risk factor for suicide; and the importance of the heterogeneous forms of depression. Depression in older people remains a significant public health problem. The burden of unrecognized or inadequately treated depression is substantial. Efficacious treatments are available. Aggressive approaches to recognition, diagnosis, and treatment are warranted to minimize suffering, improve overall functioning and quality of life, and limit inappropriate use of health care resources.

Cervical cancer.

OBJECTIVE: To provide physicians and the general public with a responsible assessment of current screening, prevention, and treatment approaches to cervical cancer. PARTICIPANTS: A non-Federal, nonadvocate, 13-member panel representing the fields of obstetrics and gynecology, gynecologic oncology, radiation oncology, and epidemiology. In addition, 28 experts in obstetrics and gynecology, gynecologic oncology, radiation oncology, gynecologic surgery, and psychology presented data to the panel and a conference audience of 500. EVIDENCE: The literature was searched through Medline and an extensive bibliography of references was provided to the panel and the conference audience. Experts prepared abstracts with relevant citations from the literature. Scientific evidence was given precedence over clinical anecdotal experience. CONSENSUS PROCESS: The panel, answering predefined questions, developed its conclusions based on the scientific evidence presented in open forum and the scientific literature. The panel composed a draft statement that was read in its entirety and circulated to the experts and the audience for comment. Thereafter, the panel resolved conflicting recommendations and released a revised statement at the end of the conference. The panel finalized the revisions within a few weeks after the conference. CONCLUSIONS: Carcinoma of the cervix is causally related to infection with the human papillomavirus (HPV). Reducing the rate of HPV infection by changes in sexual behaviors in young people and/or through the development of an effective HPV vaccine would reduce the incidence of this disease. Pap smear screening remains the best available method of reducing the incidence and mortality of invasive cervical cancer. Persons with stage IA1 disease have a high cure rate with either simple hysterectomy or, where fertility preservation is an issue, by cone biopsy with clear margins. For patients with other stage I and stage IIA disease, radical surgery and radiation are equally effective treatments. These patients should be carefully selected to receive one treatment or the other but not both, as their combined use substantially increases the cost and morbidity of treatment. Women with more advanced, nonmetastatic disease should be treated with radiation. Recurrent cervical cancer confined to the pelvis should be treated with the modality not previously received. Radiation is recommended to palliate symptoms in patients with metastatic disease.

Management of hepatitis C.

OBJECTIVE: To provide health care providers, patients, and the general public with a responsible assessment of current available methods to diagnose, treat, and manage hepatitis C. PARTICIPANTS: A non-Federal, nonadvocate, 12-member panel representing the fields of general internal medicine, hepatology, gastroenterology, infectious diseases, medical ethics, transfusion medicine, epidemiology, biostatistics, and the public. In addition, 25 experts from these same fields presented data to the panel and a conference audience of 1,600. EVIDENCE: The literature was searched through Medline and an extensive bibliography of references was provided to the panel and the conference audience. Experts prepared abstracts with relevant citations from the literature. Scientific evidence was given precedence over clinical anecdotal experience. CONSENSUS PROCESS: The panel members, answering predefined questions, developed their conclusions based on the scientific evidence presented in open forum and the scientific literature. The panel composed a draft statement that was read in its entirety and circulated to the experts and the audience for comment. Thereafter, the panel resolved conflicting recommendations and released a revised statement at the end of the conference. The panel finalized the revisions within a few weeks after the conference. CONCLUSIONS: Hepatitis C is a common infection with a variable course that can lead to chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The course of illness may be adversely affected by various factors, especially alcohol consumption. Therefore, more than one drink per day is strongly discouraged in patients with hepatitis C, and abstinence from alcohol is recommended. Initial therapy with interferon alfa (or equivalent) should be 3 million units three times per week for 12 months. Patients not responding to therapy after 3 months should not receive further treatment with interferon alone, but should be considered for combination therapy of interferon and ribavirin or for enrollment in investigational studies. Individuals infected with the hepatitis C virus should not donate blood, organs, tissues, or semen. Safe sexual practices, including the use of latex condoms, is strongly encouraged for individuals with multiple sexual partners. Expansion of needle exchange programs should be considered in an effort to reduce the rate of transmission of hepatitis C among injection drug users.

Interventions to prevent HIV risk behaviors.

OBJECTIVE: To provide health care providers, patients, and the general public with a responsible assessment of behavioral intervention methods that may reduce the risk of HIV infection. PARTICIPANTS: A non-Federal, nonadvocate, 12-member panel representing the fields of psychiatry, psychology, behavioral and social science, social work, and epidemiology. In addition, 15 experts in psychiatry, psychology, behavioral and social science, social work, and epidemiology presented data to the panel and a conference audience of 1,000. EVIDENCE: The literature was searched through Medline and an extensive bibliography of references was provided to the panel and the conference audience. Experts prepared abstracts with relevant citations from the literature. Scientific evidence was given precedence over clinical anecdotal experience. CONSENSUS PROCESS: The panel, answering predefined questions, developed its conclusions based on the scientific evidence presented in open forum and the scientific literature. The panel composed a draft statement that was read in its entirety and circulated to the experts and the audience for comment. Thereafter, the panel resolved conflicting recommendations and released a revised statement at the end of the conference. The panel finalized the revisions within a few weeks after the conference. CONCLUSIONS: Behavioral interventions to reduce risk for HIV/AIDS are effective and should be disseminated widely. Legislative restriction on needle exchange programs must be lifted because such legislation constitutes a major barrier to realizing the potential of a powerful approach and exposes millions of people to unnecessary risk. Legislative barriers that discourage effective programs aimed at youth must be eliminated. Although sexual abstinence is a desirable objective, programs must include instruction on safer sex behaviors. The erosion of funding for drug abuse treatment programs must be halted because research data clearly show that such programs reduce risky drug abuse behavior and often eliminate drug abuse itself. Finally, new research must focus on emerging risk groups such as young people, particularly those who are gay and who are members of ethnic minority groups, and women, in whom transmission of the HIV virus to their children remains a major public health problem.

National Institutes of Health Consensus Development Conference Statement: breast cancer screening for women ages 40-49, January 21-23, 1997. National Institutes of Health Consensus Developmental Panel.

OBJECTIVE: To provide heatlh care providers, patients, and the general public with a responsible assessment of currently available data regarding the effectiveness of mammography screening for women ages 40-49. PARTICIPANTS: A non-Federal, nonadvocate, 12-member panel representing the fields of oncology, radiology, obstetrics and gynecology, geriatrics, public health, and epidemiology and including patient representatives. In addition, 32 experts in oncology, surgical oncology, radiology, public health, and epidemiology, presented data to the panel and to a conference audience of 1,100. EVIDENCE: The literature was searched through Medline and an extensive bibliography of references was provided to the panel and the conference audience. Experts prepared abstracts with relevant citations from the literature. Scientific evidence was given precedence over clinical anecdotal experience. CONSENSUS PROCESS: The panel, answering predefined questions, developed its conclusions based on the scientific evidence presented in open forum and the scientific literature. The panel composed a draft statement that was read in its entirety and circulated to the experts and the audience for comment. Thereafter, the panel resolved conflicting recommendations and released a revised draft statement at the end of the conference. The final statement with a minority report was completed within several weeks after the conference. CONCLUSIONS: The Panel concludes that the data currently available do not warrant a universal recommendation for mammography for all women in their forties. Each woman should decide for herself whether to undergo mammography. Her decision may be based not only on an objective analysis of the scientific evidence and consideration of her individual medical history, but also on how she perceives and weighs each potential risk and benefit, the values she places on each, and how she deals with uncertainty. However, it is not sufficient just to advise a woman to make her own decision about mammograms. Given both the importance and the complexity of the issues involved in assessing the evidence, a woman should have access to the best possible relevant information regarding both benefits and risks, presented in an understandable and usable form. Information should be developed for women in their forties regarding potential benefits and risks to be provided to enable each woman to make the most appropriate decision. In addition, educational material to accompany this information should be prepared that will lead women step by step through the process of using such information in the best possible way for reaching a decision. For women in their forties who choose to have mammography performed, the costs of the mammograms should be reimbursed by third-party payors or covered by health maintenance organizations so that financial impediments will not influence a woman's decision. Additionally, a woman's health care provider must be equipped with sufficient information to facilitate her decisionmaking process. Therefore, educational material for physicians should be developed to assist them in providing the guidance and support needed by the women in their care who are making difficult decisions regarding mammography. The two panel members writing a minority report believed the risks of mammography to be overemphasized by the majority and concluded that the data did support a recommendation for mammography screening for all women in this age group and that the survival benefit and diagnosis at an earlier stage outweigh the potential risks.

Report of the Sinus Consensus Conference of 1996.

Retrospective data from sinus floor augmentation bone grafts were collected from 38 surgeons for 1007 sinus grafts that involved the placement of 2997 implants over a 10-year period, with the majority of the implants followed for 3 years or more postrestoration. There were 229 implant failures reported. Various root-form implants and grafting modalities were used. A consensus conference was organized to evaluate the data and reach a consensus on optimal treatment protocols. The complete database demonstrated a 90.0% success rate for implants placed in sinus grafts with at least 3 years of function. Differences in grafting materials, implant surfaces, and timing protocols were statistically analyzed. However, the database was so multivariate and multifactorial that it was difficult to draw definitive conclusions; these must await controlled prospective studies. The consensus conference therefore developed and voted on multiple consensus statements derived by committee review for bone graft materials, type of implants, timing for implant placement, failure analysis, radiographic analysis, indications/contraindications, prosthetics, and nomenclature. Several consensus statements were obtained, the most significant being that the sinus graft should now be considered a highly predictable and effective therapeutic modality.
