Improving effectiveness of clinical medicine: the need for better translation of science into practice.

Published research evidence does not automatically diffuse into clinical practice but requires active processes of translation that start with clinicians' awareness of the science and end with patient adherence to the recommended care. Many barriers thwart the uptake of valid and clinically important research into practice, with cognitive, motivational and sociological factors on the part of health professionals being among the most important. Encouraging clinicians to question the level of scientific certainty underpinning clinical practice and to actively seek evidence that may better inform clinical decisions is a priority for improving health care effectiveness. Although there are effective strategies for improving translation of research into practice, implementing them requires agreement between and buy-in from professional and managerial stakeholders.
