目的：2015年5月，韩国发生中东呼吸综合征（MERS）疫情。本研究探讨了MERS流行对韩国急诊利用率和死亡率的影响。材料与方法：采用韩国全国人口的医疗利用率和死亡率数据进行了自然实验研究。调查了每月急诊室（ER）就诊次数，以确定MERS流行期间急诊服务利用的变化;还根据患者的人口统计学因素、疾病严重程度和地区对这些趋势进行了检查。结果：与2014年6月和2016年6月的平均值相比，MERS疫情高峰期（2015年6月）的急诊就诊人数减少了33.1%。在所有年龄、性别和收入群体中均观察到了这种下降，低敏度疾病（急性中耳炎：53.0%;上呼吸道感染：45.2%）比高敏度疾病（心肌梗死：14.0%;缺血性中风：16.6%）更明显。最高急性疾病没有发现实质性变化，心脏骤停增加了3.5%，出血性卒中增加了2.4%。在7天内的ER visits.Conclusion死亡人数没有显着变化：在中东呼吸综合征流行期间，ER访问的数量下降，在所有年龄，性别和社会经济群体，并降低最急剧的低敏度疾病。尽管如此，急诊治疗后的死亡率没有显著变化。
Purpose: In May 2015, South Korea experienced an epidemic of Middle East respiratory syndrome (MERS). This study investigated the impacts of MERS epidemic on emergency care utilization and mortality in South Korea.Materials and Methods: A natural experimental study was conducted using healthcare utilization and mortality data of the entire Korean population. The number of monthly emergency room (ER) visits was investigated to identify changes in emergency care utilization during the MERS epidemic; these trends were also examined according to patients' demographic factors, disease severity, and region. Deaths within 7 days after visiting an ER were analyzed to evaluate the impact of the reduction in ER visits on mortality.Results: The number of ER visits during the peak of the MERS epidemic (June 2015) decreased by 33.1% compared to the average figures from June 2014 and June 2016. The decrease was observed in all age, sex, and income groups, and was more pronounced for low-acuity diseases (acute otitis media: 53.0%; upper respiratory infections: 45.2%) than for high-acuity diseases (myocardial infarctions: 14.0%; ischemic stroke: 16.6%). No substantial changes were detected for the highest-acuity diseases, with increases of 3.5% for cardiac arrest and 2.4% for hemorrhagic stroke. The number of deaths within 7 days of an ER visit did not change significantly.Conclusion: During the MERS epidemic, the number of ER visits decreased in all age, sex, and socioeconomic groups, and decreased most sharply for low-acuity diseases. Nonetheless, there was no significant change in deaths after emergency care.
