背景哮喘急性发作的住院情况因季节而异，然而，其潜在的气候原因尚未得到充分的探索。本研究旨在探讨天气因素对因哮喘症状加重而住院人数增加的影响。这将为有关部门根据青岛的天气情况分配适当的医疗资源提供更多信息，中国说。方法选择青岛市13家主要医院2017年1月1日至2019年12月31日收治的成人哮喘急性发作期患者。临床资料来自电子病历(EMR)系统，包括年龄、性别、吸烟史等。青岛市2017年至2019年的逐时空气质量，包括空气质量指数(AQI)、PM2.5和PM10，来自中国国家环境监测中心。2017-2019年的所有这些参数都是按月进行比较的。气象资料方面，利用美国国家环境预报中心(NCEP)和美国国家大气研究中心(NCAR)的全球再分析资料，计算了1960-2020年850hPa月水平风和500hPa月垂直风速。采用相关分析方法，确定每月哮喘住院人数与大气压力、湿度、垂直能见度等环境因素的相关性。结果10549例哮喘住院患者(男45.7%，女54.3%)纳入研究。2019年3月至6月，哮喘恶化住院人数处于平台期，PM2.5和PM10水平较高，2019年1月至3月空气质量较差，可能受到2018年厄尔尼诺事件的影响。然而，哮喘住院次数与所有环境因素的平均值之间没有显著的相关性。结论2019年春季青岛市哮喘急性加重期住院率较高与不利天气条件有关，可能与东亚大气环流有关。
Background The hospitalization for asthma exacerbation has varied with seasons, however, the underlying weather reasons have not been fully explored yet. This study is aimed to explore the effect of weather factors on increased number of hospitalization due to worsening of asthma symptoms. This will provide more information to the relevant authorities to allocate appropriate medical resources as per the weather conditions in Qingdao, China. Methods All adult patients admitted for asthma exacerbation from 1 January, 2017 to 31 December, 2019 were enrolled from 13 main hospitals of Qingdao. The clinical data, including age, sex, smoking history, etc., were collected from the electronic medical record (EMR) systems. The hourly air quality of Qingdao from 2017–2019, including the air quality index (AQI), PM2.5 and PM10, was obtained from the China National Environmental Monitoring Centre. All these parameters during 2017–2019 were compared monthly. For meteorological data, the monthly horizontal wind at 850 hPa and vertical velocity at 500 hPa during 1960–2020 were obtained from National Center for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR) global reanalysis dataset. The correlation analysis was applied to determine the association between asthma hospitalizations and the environmental factors, including atmospheric pressure, humidity, vertical visibility, and etc., monthly. Results In all, 10,549 asthmatic inpatients (45.7% males, 54.3% females) were included in the study. The inpatients number for asthma exacerbation had a plateau lasting from March to June of 2019, accompanied with high PM2.5 and PM10, as well as bad air quality from January to March of 2019, potentially governed by the El Niño event in 2018. However, there was no significance correlation between the number of asthma hospitalizations and the average value of all environmental factors. Conclusions The high rate of hospitalization for asthma exacerbation in Qingdao during the spring of 2019 was associated with the unfavorable weather conditions, which might be linked to the atmospheric circulation in East Asia.
