Ambient Air Quality Exposure Among Pediatric Patients CHLA

Exposure to poor air quality can adversely impact the health of children and contribute to the development and exacerbation of asthma. Despite the risk that air quality can have on the health of children, knowledge of air quality exposure for children seen across an entire pediatric health system is not known. The purpose of this study is to understand the epidemiology of air quality exposure among all children and children with a diagnosis of asthma seen across the Children’s Hospital Los Angeles from 2017-2023. We will conduct this study through spatial analysis of electronic health records and physical and environmental determinants of health. Through overlaying geographic contextual data on social, economic, and environmental exposure data with patient records, our study can educate health care professionals, health system leaders, policymakers, and foster advancement in pediatric health system delivery.
