【摘要】：目的了解冬季呼吸系统疾病门诊患者就诊的主要临床症状、初步诊断与空气质量和温度的相关性。方法调查2012年11月1日至2013年2月28日本院呼吸科门诊患者记录资料;在当地环境保护和气象部门分别调查同期空气质量和天气状况资料。分析该时间段呼吸系统疾病门诊患者就诊例次数、主要呼吸系统症状、门诊初步诊断疾病病种、空气污染指数(API)、气温变化。将API和气温与呼吸科门诊患者例次数、主要症状和疾病诊断进行相关分析。结果 API与当日、滞后1 d和3 d的就诊例次数均存在正相关,pearson相关系数分别为0.725、0.331和0.257(P0.01)。其中,API与滞后1天和3天的就诊例次数的相关系数低于API与当日就诊例次数的相关系数。API值分段分析,平均日就诊例次数每一级依次递增21.4%、42.6%和50.4%,症状和诊断病例数也有不同程度递增。API与咳痰、气喘存在正相关,pearson相关系数分别为0.287和0.277(P0.01)。API与上呼吸道感染、支气管炎、支气管哮喘和肺炎存在正相关,pearson相关系数分别为0.184、0.251、0.301和0.227(P0.05)。气温在-3℃~15℃之间平均日就诊例次数基本稳定,而-4℃~-3℃时平均日就诊例次数增加34.5%,-5℃~-4℃时平均日就诊例次数再增加9.3%。对气温较敏感的症状是咳嗽,-4℃~-3℃时例次数增加35.7%,-5℃~-4℃时例次数再增加14.0%。气温与鼻窦炎、支气管哮喘和咳痰存在负相关,pearson相关系数分别为-0.194、-0.383和-0.191(P0.05)。结论冬季呼吸门诊患者就诊例次数随着API增加而增多,呼吸系统疾病和症状与空气质量和温度密切相关。
[Abstract]:Objective to investigate the main clinical symptoms of outpatients with respiratory diseases in winter. Methods from November 1st 2012 to February 2013, the data of respiratory outpatients were investigated. The data of air quality and weather condition in the same period were investigated in the local environmental protection and meteorological department. The number of outpatient visits and the main respiratory symptoms were analyzed in this period. Primary diagnosis of diseases, air pollution index (API), temperature change. API and temperature were compared with the number of outpatients in respiratory department. Results the positive correlation Pearson correlation coefficient was 0.725 between API and the patients who were delayed 1 d and 3 d respectively. 0.331 and 0.257 (P0.01). The correlation coefficient between API and the number of visits delayed by 1 and 3 days was lower than that between API and the number of visits on the same day. The average number of visits per day increased by 42.6% and 50.4% in turn. There was also a positive correlation between symptoms and the number of diagnosed cases. API was positively correlated with expectoration and asthma. The correlation coefficients of pearson were 0.287 and 0.277 respectively (P 0.01). There was a positive correlation between pearson and upper respiratory tract infection, bronchitis, bronchial asthma and pneumonia. The correlation coefficients of pearson were 0.184 ~ 0.251 ~ 0.301 and 0.227 ~ (-1) P _ (0.05), respectively. The average number of visits per day between 3 鈩，
