[Evidence-based medicine. How to use biomedical literature to solve clinical problems. Italian Group on Evidence-Based Medicine-GIMBE].
Clinical practice is constantly changing, the rate of changing is accelerating and consequently it may even take years before the results of clinical research will be incorporated in day-to-day practice. So, there is a large gap between what the biomedical literature contains and the care that most of patients receive. The gap is widened by the extensive processing that results of clinical research require before they can be used. Evidence-based medicine is a new approach to health care promoting the collection, interpretation, and integration of valid, important and applicable research-derived evidence. The best available evidence, moderated by patient circumstances and preferences, is applied to improve the quality of clinical judgements. There are many information tools that facilitate the practice of evidence-based medicine. These include users' guides to the medical literature, strategies to improve the yield of MEDLINE searches, standardized formats for abstracts of journal articles and guidelines, new journals, systematic reviews and meta-analyses, resources on-line and software tools bringing high quality information to the point of clinical decision making. However, these tools are poorly spread and physicians lack of necessary skills for their effective utilization. In this article the authors describe guidelines for efficient and effective utilization of biomedical information tools to solve clinical problems and improve the quality and the cost/effectiveness of health care.
