Emergency hospital utilization rates for asthma remain high despite advances in asthma controller medications and the presence of widely accepted asthma treatment guidelines. To explore this phenomenon, we analyzed administrative data to determine characteristics of patients seen in the emergency department (ED) for asthma. Complete pharmacy and diagnostic coding records were obtained from consecutive adults (aged 19-56 years) treated for asthma in the ED of a closed-network health maintenance organization between April and July of 2002.
