Synopsis

These investigators recruited 391 adults at least 60 years of age with uncontrolled moderate or severe asthma from 9 primary care practices, excluding patients with other pulmonary diseases or more than a 15 pack-year smoking history. The patients were randomized, allocation concealment uncertain, to remain in usual care or to receive the intervention either at home or in the office. The intervention comprised 3 elements delivered by an asthma care coach: (1) identifying barriers to asthma self-management, (2) targeted actions to address these barriers, and (3) reinforcement over time. Over 1 year, this coaching improved asthma-related quality of life, and emergency department visits occurred less often in patients who received the intervention (odds ratio = .8; 95% CI .6 - .99). Asthma control scores and inhaler technique were both improved in the intervention groups. The intervention was equally effective when provided in the office or at home.
