Evidence-based Practice

چکیده
Making decisions about medical therapy is increasingly challenging as new medications arrive on the market and new scientific research outdates previously accepted therapeutic standards. This challenge is especially difficult when a treatment decision must be made urgently due to the high morbidity or mortality associated with a suspected diagnosis. In these situations, information must be quickly accessible and of high quality to ensure prompt institution of therapy based on the best available evidence. This article uses a case of acute bacterial meningitis to demonstrate how to find, appraise, and apply the best available evidence when faced with making an urgent therapy decision. Most published trials addressing therapeutic options compare one treatment to another, following for defined outcomes. Understanding how these trials are appraised and how to use the resulting information is critical for successful patient care. In urgent clinical settings, time does not always allow us to do this critical appraisal prior to instituting therapy. In these situations, prescreened evidence-based medicine (EBM) resources are becoming a reliable source of critical information. Use of these databases allows fast access to the best clinical evidence during busy clinics or rounds. Treatment decisions thus can be reached during active patient care in much less time than required for individual appraisal of relevant therapy studies.
