摘要
目的了解2020年苏州市可吸入颗粒物(inhalable particulate matter,PM_(10))、细颗粒物(fine particulate matter,PM_(2.5))、NO_(2)、臭氧1 h(ozone 1 hour,O_(3-1 h))和臭氧8 h(ozone 8 hours,O_(3-8 h))等主要空气污染物浓度对医院门诊就诊量的影响。方法收集2020年1月1日—12月31日苏州市大气污染物监测资料和4家综合性医院门诊就诊资料,分析空气污染物浓度与门诊就诊量之间的关系。结果2020年苏州市4家综合性医院年门诊总量为4576674人次,呼吸系统门诊量为352318人次,日均总门诊中位数为13319(9963,15792)人次,日均呼吸系统门诊中位数为[875(637,1195)]人次。大气污染物PM_(10)、PM_(2.5)、NO_(2)、O_(3-1h)、O_(3-8h)、SO_(2)、CO的日均中位浓度为38.0(30.0,56.0)μg/m^(3)、26.0(19.0,40.0)μg/m^(3)、29.0(21.0,40.0)μg/m^(3)、115.0(84.0,153.0)μg/m^(3)、99.0(72.0,133.0)μg/m^(3)、6.0(5.0,7.0)μg/m^(3)和0.6(0.5,0.8)mg/m^(3)。总门诊量及各系统门诊量全年(除2—3月)总体分布特征与往年相比较为一致,但门诊量(除循环系统门诊量)在2月出现急剧减少,3月后又开始迅速回升,以呼吸系统门诊量变化最为明显。空气质量达标日与超标日的总门诊量比较,差异有统计学意义(P<0.05)。对影响苏州市空气质量的主要污染物PM_(2.5)日均浓度进行分级分析,不同PM_(2.5)日均浓度总门诊量及各系统门诊量(除循环系统门诊量)比较,差异有统计学意义(P<0.05)。结论苏州市空气污染物浓度的增加可能对门诊就诊量的增加有一定影响,为保障群众健康,应采取措施改善空气质量。
Objective To explore the effect of concentration of main air pollutants,including inhalable particulate matter(PM_(10)),fine particulate matter(PM_(2.5)),nitrogen dioxide(NO_(2)),ozone 1 hour(O_(3-1 h))and ozone 8 hours(O3-8 h),on the hospital outpatient visits in Suzhou City in 2020.Methods The monitoring data of air pollutants and outpatient data of four general hospitals in Suzhou City from January 1 to December 31,2020 were collected,and the relationship between air pollutant concentration and outpatient visits was analyzed.Results In 2020,the total number of outpatient visits of four general hospitals in Suzhou City was 4576674,the number of respiratory outpatient visits was 352318,the median daily total outpatient service was 13319(9963,15792),and the median daily respiratory outpatient service was 875(637,1195).The daily median concentration of PM_(10),PM_(2.5),NO_(2),O_(3-1 h),O_(3-8 h),sulfur dioxide(SO_(2))and carbon monoxide(CO)was 38.0(30.0,56.0)μg/m^(3),26.0(19.0,40.0)μg/m^(3),29.0(21.0,40.0)μg/m^(3),115.0(84.0,153.0)μg/m^(3),99.0(72.0,133.0)μg/m^(3),6.0(5.0,7.0)μg/m^(3) and 0.6(0.5,0.8)mg/m^(3),respectively.The overall distribution characteristics of total outpatient visits and outpatient visits of all systems throughout the year,except from February to March,were relatively consistent with that of previous years.However,outpatient visits,except for those of circulatory system,decreased sharply in February and began to rise rapidly after March,with the most obvious change in outpatient visits of respiratory system.There was statistically significant difference in the total outpatient visits between the days of air quality reaching the standard and exceeding the standard(P<0.05).The average daily concentration of PM2.5,the main pollutant affecting the air quality of Suzhou City,was classified and analyzed,and the differences in the total outpatient visits and outpatient visits of all systems,except circulatory system,were statistically significant under different PM2.5 average daily concentrati
