IntroductionAlthough helicopters have been used in an air ambulance system for the past decade in Japan, the appropriate selection of patients for this transport mode has not been investigated. The present study investigates which patients could potentially benefit the most from helicopter emergency medical service (HEMS).MethodsWe investigated the extent of circulatory and respiratory support required in the intensive care unit (ICU) and ultimate outcomes of 2340 patients with cardiovascular disease admitted to 1 institution between October 2001 and December 2009. Two hundred and seventy were transported by HEMS (HEMS group), and 2070 were transported by other means (non-HEMS group).ResultsTemporary cardiac pacing, ventilator management, intra-aortic balloon pumping, percutaneous cardiopulmonary support, electrical defibrillation, and therapeutic hypothermia were more frequently required by patients in the HEMS group vs. the non-HEMS group (10.4%, 28.1%, 17.0%, 5.2%, 10.0% and 3.4% vs. 8%, 17.9%, 10.9%, 2.3%, 4.5% and 0.4%, respectively). The mortality rate was higher in the HEMS group than in the non-HEMS group in the ICU (9.6% vs. 5.3%).ConclusionDisease was more clinically severe and the outcome was poorer among patients with cardiovascular diseases transported by HEMS than by other means.Copyright © 2011 Air Medical Journal Associates.
