Paediatric asthma and air quality
*Which children come back to the emergency department after an asthma visit, and how much does air quality matter?*
One row per emergency visit for asthma at Lakeside Children's Hospital, 2023–2025, for children aged 2 to 17. Each visit carries the weekly mean PM2.5 for the child's home county, prior visits in the last year, whether the child was admitted, length of stay and readmission within 30 days.
