Emergency medical services (EMS) is an invaluable healthcare resource, providing life-saving care in the prehospital setting. During the COVID-19 pandemic, there have been concerns that healthcare resources, including EMS, would be overwhelmed by the potential surge in critically ill patients. This study seeks to determine the impact of the COVID-19 pandemic on EMS utilization in the state of Maryland.
A retrospective review of data from the Maryland Emergency Medical Services Data System was performed. EMS call volumes were compared from March 1 to August 31 in the years 2018, 2019, and 2020. In addition, adult cases from the three time periods that contained an EMS impression of stroke, cardiac arrest, asthma, traumatic injury, ST elevation myocardial infarction (STEMI), sepsis, and overdose were also analyzed.
There was a significant decrease in overall EMS call volumes in the state of Maryland in the first 6 months of 2020 compared to the prior 2 years. While the total number of calls decreased, a higher proportion of patients in 2020 had EMS impressions of cardiac arrest, STEMI, stroke, and traumatic injury compared to the previous 2 years. Additionally, there was an increase in termination of resuscitation for out of hospital cardiac arrest.
In the state of Maryland, overall call volumes decreased, but the proportion of EMS patients with time-sensitive illnesses increased during the COVID-19 pandemic.
紧急医疗服务(EMS)是一种宝贵的医疗资源,在院前环境中提供救生护理。在 COVID-19 大流行期间,人们担心包括 EMS 在内的医疗资源可能会因潜在的危重病患者激增而不堪重负。本研究旨在确定 COVID-19 大流行对马里兰州 EMS 使用的影响。
对马里兰州紧急医疗服务数据系统的数据进行回顾性分析。比较了 2018 年、2019 年和 2020 年 3 月 1 日至 8 月 31 日期间的 EMS 呼叫量。此外,还分析了三个时间段中包含 EMS 印象为中风、心搏骤停、哮喘、创伤性损伤、ST 段抬高型心肌梗死 (STEMI)、脓毒症和药物过量的成年病例。
与前两年相比,2020 年马里兰州 EMS 呼叫总量在前 6 个月显著下降。尽管呼叫总数减少,但 2020 年有 EMS 印象的心搏骤停、STEMI、中风和创伤性损伤的患者比例高于前两年。此外,院外心脏骤停的复苏终止率有所增加。
在马里兰州,总体呼叫量下降,但 COVID-19 大流行期间,具有时间敏感性疾病的 EMS 患者比例增加。
