한국 응급의료 전용헬기 초기 1년간 운영 결과 분석

Abstract

Purpose: HEMS is expected to shorten transportation timeto an advanced facility and to enable administration ofadvanced treatment at the scene. In Korea, HEMS waslaunched in September 2011. The aim of this study is toprovide an overview of HEMS in South Korea during thefirst year and to provide information for use in improvement. Methods: Data were collected from September 23. 2011 toSeptember 22. 2012; emergency patients on islands and invulnerable areas were transported by helicopter. During theone-year study period, a prospective cohort study was conducted. Target diseases were acute coronary syndrome,stroke, and severe trauma. We classified patients accordingto two groups (severe group vs. mild group), whether theyhad been admitted to the intensive care unit (included deathin the emergency room) or not. Results: During this period, the total request mission numberwas 555 and the number of patients transported tobase hospitals was 322. Differences between severe groupand minor group were as follows: (1) final diagnosis; severetrauma (27.7% vs. 3.5%), cerebrovascular accident (CVA)(24.3% vs. 4.2%), and acute coronary syndrome (7.3% vs. 2.1%), p<0.001. (2) classification of transport area; islands(45.8% vs. 77.2%), bridge islands (26.0% vs. 15.9%), andinland area (28.3% vs. 6.9%), p<0.001. (3) the median timeof call to hospital time was 52 vs. 55 minutes (p=0.289). and the median time of on scene time was 9 vs. 8 minutes(p=0.046). Conclusion: During the 12-month period, air ambulanceplayed an important role in medically vulnerable areas(inclusion islands). However, the number of transport missionswas still relatively low, and has shown a gradualincrease.
