Helicopter EMS Transport Outcomes Literature: Annotated Review of Articles Published 2004-2006

Helicopter EMS (HEMS) andits possible association with outcomes improvement continues to be a subject of debate. As is the case with other scientific endeavors, debate over HEMS usefulness should be framed around an evidence-based assessment of the relevant literature. In an effort to facilitate the academic pursuit of assessment of HEMS utility, in late 2000 the National Association of EMS Physicians' (NAEMSP) Air Medical Task Force prepared annotated bibliographies of the HEMS-related outcomes literature. As a result of that work, two review articles, one covering HEMS use in nontrauma andthe other in trauma, published in 2002 in Prehospital Emergency Care surveyed HEMS outcomes-related literature published between 1980 andmid-2000. The project was extended with a 2004 review that covered the literature published between 2000 and2003. The current review continues the series, outlining outcomes-associated HEMS literature from 2004 through 2006.
