In Academic Emergency Medicine, Margaret Samuels-Kalow and colleagues, including Karin Rhodes and Cynthia Mollen, explore patient-reported outcome measures for Emergency Department care among asthma patients. As existing patient-reported outcome measures have limited applicability to emergency medicine, the authors seek to identify patient-centered concepts specific to emergent asthma care. They completed a three-phase qualitative study, in which adult asthma patients and parents of pediatric asthma patients identified important concepts for post-ED discharge success. These concepts were: symptom improvement, access to medication and supplies, correct medication use, and sufficient knowledge. These data are first patient-derived outcome measure for ED patients with asthma, and future researchers may use this information to develop and validate specific patient-centered outcome measures.
