Evidence-based critical care medicine: A potential tool for change

This issue of New Horizons is about change. While our traditional apprenticeship model of physician training has served us well, adaptation is required for the new millennium. Among several sectoral trends in medicine, two are particularly relevant for intensivists: a) the information explosion and b) increased accountability to society regarding effective, efficient, compassionate, and culturally sensitive care. Evidence-based medicine (EBM) (or any other single initiative, for that matter) is not going to address all of tomorrow's challenges. However, EBM does help by enhancing clinical informatics and critical appraisal skills so that clinicians are better able to keep up with the growing literature, and decide whether, and if so, this literature applies to individual patients. In addition, EBM can help to highlight the determinants of clinical decisions, which may include contributions of caregiver knowledge, patient pathophysiology, research evidence, patient and societal values, and increasingly, costs. While EBM is best practiced at the individual level, its application to other aspects of health care is growing.
