Abstract

Wildfires are becoming increasingly common in Canada and the United States. Smoke produced from these fires creates a multitude of air pollution constituents that can cause breathing and other health issues for humans, particularly those with asthma and other respiratory conditions. Of these pollutants, PM2.5 (particulate matter that is 2.5 microns or smaller) is particularly problematic as these particles are inhaled deep into lung tissue, where they create inflammation and oxidative stress. Poor air quality can also trigger asthma and respiratory issues, leading to an increase in emergency department admissions for breathing treatments. The goal of this study is to examine the effects of a Canadian wildfire event in September of 2023 on hospital admissions in Douglas County, Nebraska. Local hospital admission data for Douglas County, Nebraska was used to determine asthma-related emergency department visits along with local air quality data from the Douglas County Health Department that includes PM2.5 air quality data. These data sets will be used to determine if poor air quality can negatively impact individuals and whether it increases emergency department admissions. This study can help provide advanced public health communications and assist hospital teams for a potential increase in patients following a wildfire event. In addition, the information can be used to help the public prepare for these events in advance.
