BackgroundWhile national guidelines recommend the use of therapeutic hypothermia (TH) for the treatment of out-of-hospital cardiac arrest (OHCA), adoption of the technique has been slow. In addition, little is known about how TH is applied in practice. This study sought to characterize the adoption and implementation of TH by acute care hospitals in the state of New Jersey.MethodsA survey of all 73 acute care hospitals in New Jersey was conducted to solicit information about TH adoption, application, and methods. Additional information was gained through a review of 18 written TH protocols (covering 21 hospitals).ResultsAfter growing slowly from 2004 to 2008, TH use among New Jersey hospitals accelerated between 2009 and 2011. By 2011, 68.4% of New Jersey hospitals had a TH program in place, with an additional 13.6% indicating plans to begin one. Most hospitals indicated low volumes of OHCA patients (e.g., ≤10 per month). There was no relationship between OHCA volume and development of a TH program. The per hospital volume of OHCA patients receiving TH is even lower given the extensive patient exclusion criteria used by many facilities. TH hospitals vary widely in their TH exclusion criteria and cooling equipment and methods.DiscussionThe vast majority of New Jersey hospitals are now organized to implement national TH guidelines for initial survivors of OHCA. However, limited volumes of OHCA cases per hospital and lack of uniformity on how the guidelines are implemented raise new questions about the effectiveness of current practice in postarrest care. More detailed analysis of TH volumes versus outcomes and comparative studies of TH techniques are required to optimize postarrest care.
