Abstract

OBJECTIVE

In Philadelphia, a scrapyard fire generated PM2.5 concentrations >1000 μg/m. We assessed whether this was associated with pediatric emergency department visits for respiratory diagnoses.

DESIGN/METHODS: Retrospective observational study using electronic health record data from a local, academic pediatric hospital.

RESULTS

Compared to the two-week period before the fire, patients living directly north of the fire (downwind) had a significant difference in all asthma diagnoses (OR = 3.02, P = 0.03); asthma and upper respiratory infection (OR = 17.3, P = 0.01); overall admissions (OR = 3.04, P = 01); asthma admissions (OR = 4.45, P = .01); and asthma and upper respiratory infection admissions (OR = 15.0, P = 0.01). We did not observe any significant differences among visits or admissions from patients residing in other adjacent zip codes.

CONCLUSION

A localized, transient increase in PM2.5 was associated with increased pediatric emergency department visits for asthma among patients living downwind of the fire.

摘要

目的

在费城，一场废品场大火导致 PM2.5 浓度超过 1000μg/m。我们评估了这是否与儿科急诊就诊的呼吸诊断有关。

方法/设计：使用当地学术儿科医院的电子健康记录数据进行回顾性观察性研究。

结果

与火灾前两周相比，居住在火灾正北方（下风处）的患者所有哮喘诊断（OR=3.02，P=0.03）、哮喘和上呼吸道感染（OR=17.3，P=0.01）、总体入院（OR=3.04，P=0.01）、哮喘入院（OR=4.45，P=0.01）和哮喘和上呼吸道感染入院（OR=15.0，P=0.01）的差异均有统计学意义。我们未观察到居住在其他相邻邮编的患者就诊或入院的任何显著差异。
