Once-daily antiretroviral therapy: Spanish Consensus Statement.

BACKGROUND: Administration of antiretroviral therapy (ART) once daily is creating extraordinary interest among the members of the scientific community and also among those who receive the therapy. However, in clinical practice, some doubts remain about its use. OBJECTIVES: This document examines the characteristics and possibilities of treatment administered once daily. METHODS: Consensus of 248 Spanish experts in the field. RESULTS: Once-daily dosing is considered an added value which could favour adherence and, therefore, efficacy, as well as the quality of life of certain patients, however, the objective of adequate adherence in the long term is often difficult to achieve regardless of the treatment used. In theory, any patient can receive once-daily therapy, although some patients could particularly benefit from it, e.g. those with unfavourable social or personal circumstances, including drug users, patients whose treatment must be supervised, patients receiving multiple medications, or those who need rescue therapy after multiple treatment failures. At present, it is possible to design once-daily ART using some of the combinations of drugs considered as first-choice in national and international recommendations for antiretroviral therapy, but the options are still limited. The marketing of new drugs with this characteristic could allow us to increase the number and types of patient who can benefit from once-daily regimens, including those patients who need rescue therapy. CONCLUSIONS: Once-daily ART is a good alternative to regimens administered several times each day when a potent combination of active drugs is available.

The consensus statements on adjuvant chemotherapy in breast cancer. Fact or artifact.

The decision of the National Cancer Institute, in November of 1985, in favor of adjuvant chemotherapy in the treatment of the premenopausal patient was based on the analysis of randomized clinical trials. The authors have carefully evaluated five papers dealing with the trials and found in each of them some problem in the performance or statistics which makes us question the interpretation of the findings of a statistically significant advantage for adjuvant chemotherapy in premenopausal patients. In view of this, we suggest that all the studies being considered need to be checked for their validity and if a significant number have similar flaws to those in the five trials noted, then we suggest that it is not possible to come to conclusions reported by the consensus panel.

Essential elements of communication in medical encounters: the Kalamazoo consensus statement.

In May 1999, 21 leaders and representatives from major medical education and professional organizations attended an invitational conference jointly sponsored by the Bayer Institute for Health Care Communication and the Fetzer INSTITUTE: The participants focused on delineating a coherent set of essential elements in physician-patient communication to: (1) facilitate the development, implementation, and evaluation of communication-oriented curricula in medical education and (2) inform the development of specific standards in this domain. Since the group included architects and representatives of five currently used models of doctor-patient communication, participants agreed that the goals might best be achieved through review and synthesis of the models. Presentations about the five models encompassed their research base, overarching views of the medical encounter, and current applications. All attendees participated in discussion of the models and common elements. Written proceedings generated during the conference were posted on an electronic listserv for review and comment by the entire group. A three-person writing committee synthesized suggestions, resolved questions, and posted a succession of drafts on a listserv. The current document was circulated to the entire group for final approval before it was submitted for publication. The group identified seven essential sets of communication tasks: (1) build the doctor-patient relationship; (2) open the discussion; (3) gather information; (4) understand the patient's perspective; (5) share information; (6) reach agreement on problems and plans; and (7) provide closure. These broadly supported elements provide a useful framework for communication-oriented curricula and standards.

National Institutes of Health Consensus Development Conference Statement: diagnosis and treatment of attention-deficit/hyperactivity disorder (ADHD)

Attention-deficit/hyperactivity disorder (ADHD) is a commonly diagnosed behavioral disorder of childhood that represents a costly major public health problem. Despite progress, ADHD and its treatment have remained controversial, especially the use of psychostimulants for both short- and long-term treatment. Although an independent diagnostic test for ADHD does not exist, there is evidence supporting the validity of the disorder. Studies (primarily short-term, approximately 3 months), including randomized clinical trials, have established the efficacy of stimulants and psychosocial treatments for alleviating the symptoms of ADHD and associated aggressiveness and have indicated that stimulants are more effective than psychosocial therapies in treating these symptoms. Because of the lack of consistent improvement beyond the core symptoms and the paucity of long-term studies (beyond 14 months), there is a need for longer-term studies with drugs and behavioral modalities and their combination. Although trials are under way, conclusive recommendations concerning treatment for the long term cannot be made at present. There are wide variations in the use of psychostimulants across communities and physicians, suggesting no consensus regarding which ADHD patients should be treated with psychostimulants, and thus the need for improved assessment, treatment, and follow-up. Furthermore, the lack of insurance coverage, preventing the appropriate diagnosis and treatment of ADHD, and the lack of integration with educational services are substantial barriers and represent considerable long-term costs for society. Finally, after years of clinical research and experience with ADHD, knowledge about the cause or causes of ADHD remain largely speculative. Consequently, there are no documented strategies for the prevention of ADHD.
