北京隆福医院1991年非预约门诊就诊人次与大气污染之间的关系

Association of Air Pollution with Unscheduled Outpatient Visits in Beijing Longfu Hospital, 1991

分析北京隆福医院1991年门诊就诊人次,以估计大气污染与每日门诊就诊人次之间的关系。总飘尘含量(TSP)测定天数224天(平均359μg/m^3),二氧化硫(SOD测定天数221天(平均124μg/m^3)。采用线性回归估计TSP和SO_2的影响,把温度、湿度和工作日作为协变量进行调整,并对时序数据进行马尔可夫自动相关校正。在TSP和非外科就诊人次间存在显著的暴露-反应关系,但与外科就诊人次间无显著性。SO_2仅与儿科就诊人次存在显著性关系。

Outpatient visits to Beijing Longfu Hospital, a community--based hospital, were analyzed to assess the association of air pollution with daily outpatient visits in 1991. Measurements of total suspended particulate (TSP) were available for 224 days (mean was 359μg/m^3) and sulfur dioxide (SO_2)for 221 days (mean was 124μg/m^3). The effects of TSP and SO_2 were assessed by linear regressions adjusting for temperature, humidity, seasons and the workdays as covariables with a Markov correction for auto-correlation in time series data. There was a significant exposureresponse relationship between TSP level and non-surgery outpatient visits but not for surgery visits. SO_2 was only significantly associated with pediatric visits.
