Implementation of therapeutic hypothermia guidelines for post-cardiac arrest syndrome at a glacial pace: Seeking guidance from the knowledge translation literature

Abstract

The 2005 International Liaison Committee on Resuscitation (ILCOR) Consensus on Science and Treatment Recommendations document represents the most extensive and rigorous systematic review of the resuscitation literature to date and included evidence-based recommendations for post-resuscitation care. A new recommendation for the induction of mild therapeutic hypothermia for comatose cardiac arrest survivors was included in this document. Accordingly, constituent national member associations of ILCOR, including the American Heart Association, incorporated the recommendation for therapeutic hypothermia into their respective guidelines. Despite these endorsements there is a concern that therapeutic hypothermia is not being used in practice. Data from a number of surveys in Europe and the United States suggest that rates of use among physicians may be as low as 30-40%. Despite the cost and effort associated with the production of these guidelines and the potential impact on patient care, current efforts in implementing the guideline have not achieved widespread success. This commentary explores the issue of underutilization of the American Heart Association guidelines for therapeutic hypothermia and looks to the knowledge translation literature to inform a new approach to implementation. We will review the underlying phenomenon of research implementation into practice, specific barriers to guideline implementation and interventions that may improve therapeutic hypothermia uptake.
