For persons with asthma who have a peak flow meter at home (ASTHPEAKHMRD), ASTHPEAKUSRD reports if the person has ever used their peak flow meter. Persons who are in scope in round 5 of the panel in relative year 2 or round 3 of the panel in relative year 1, who reported ever being diagnosed with asthma, and who indicated they still had asthma or had an episode/attack of asthma in the past 12 months answered additional questions about asthma medication and peak flow meters.
