RT Journal Article SR Electronic T1 Strategies for implementing implementation science: a methodological overview JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 660 OP 664 DO 10.1136/emermed-2015-205461 VO 33 IS 9 A1 Margaret A Handley A1 Anuradha Gorukanti A1 Adithya Cattamanchi YR 2016 UL http://emj.bmj.com/content/33/9/660.abstract AB A key reason for the consistent gaps between evidence and practice across all areas of medicine is that there has been little attempt to identify or target factors critical for successful implementation of an evidence-based intervention. There is either no explicit implementation strategy or the strategy is based on a best guess rather than on a systematic assessment of crucial barriers and enablers. A different approach is needed to close the evidence–practice gap and thereby achieve the triple aim of improved health, improved patient experience and reduced healthcare costs. We present three fundamental principles of implementation science, which is a methodology that offers a systematic and comprehensive approach to improving healthcare practice and a series of ‘how to’ steps to conduct implementation science research. In an accompanying article, a scoping review of the types of implementation science research conducted in emergency medicine is reviewed, and several of the principles related to this review are discussed.
