Rose M. Chasm, MD, and Veronica Pei, MD, MPH, MEd, are the lead authors of the article titled “Sex Differences in Risk of Hospitalization Among Emergency Department Patients with Acute Asthma,” published in the July issue of Annals of Allergy, Asthma, and Immunology. This report is based on a study by the Multicenter Airway Research Collaboration, involving 2000 patients treated in 48 academic and community hospital emergency departments. Its findings are strikingly similar those published by the MARC in 1999: women remain at higher risk of hospitalization than men following an exacerbation, even though they are more likely to be under the care of an asthma specialist and to be following guideline-recommended pathways for the long-term management of asthma.
