Exposure to high temperatures is detrimental to human health. As climate change is expected to increase the frequency of extreme heat events, and raise ambient temperatures, an investigation into the trend of heat-related emergency department (ED) visits over the past decade is necessary to assess the human health impact of this growing public health crisis. ED visits were examined using the Nationwide Emergency Department Sample. Visits were included if the diagnostic field contained an ICD-9-CM or ICD-10-CM code specific to heat-related emergency conditions. Weighted counts were generated using the study design and weighting variables, to estimate the national burden of heat-related ED visits. A total of 1,078,432 weighted visits were included in this study. The annual incidence rate per 100,000 population increased by an average of 2.85% per year, ranging from 18.21 in 2009, to 32.34 in 2018. The total visit burden was greatest in the South (51.55%), with visits increasing to the greatest degree in the Midwest (8.52%). ED visit volume was greatest in July (29.79%), with visits increasing to the greatest degree in July (15.59%) and March (13.18%). An overall increase in heat-related ED visits for heat-related emergency conditions was found during the past decade across the United States, affecting patients in all regions and during all seasons.
暴露在高温下对人类健康有害。随着气候变化预计会增加极端高温事件的频率,并提高环境温度,有必要调查过去十年与热有关的急诊部(ED)就诊趋势,以评估这种日益严重的公共卫生危机对人类健康的影响。ED 就诊使用全国急诊部样本进行检查。如果诊断字段包含特定于与热有关的紧急情况的 ICD-9-CM 或 ICD-10-CM 代码,则将就诊包括在内。使用研究设计和加权变量生成加权计数,以估计与热有关的 ED 就诊的全国负担。这项研究共包括 1,078,432 次加权就诊。每年每 10 万人的发病率平均每年增加 2.85%,从 2009 年的 18.21 增加到 2018 年的 32.34。南部(51.55%)的就诊总负担最大,中西部(8.52%)的就诊增加幅度最大。ED 就诊量最大的是 7 月(29.79%),就诊量最大的是 7 月(15.59%)和 3 月(13.18%)。在过去十年中,美国各地与热有关的紧急情况有关的 ED 就诊量总体呈上升趋势,影响到所有地区和所有季节的患者。
