Better Outcomes of Asthma Treatment—BOAT

A. Sonia Buist, Principal Investigator,
William M. Vollmer, Thomas M. Vogt, Co-Investigators

 BOAT develops and evaluates the effectiveness of a new model of clinician-patient interaction, shared decision-making, in improving outcomes in adults aged 18-70 years with poorly controlled, mild to moderate persistent asthma. BOAT will compare the shared decision-making model in a randomized, controlled clinical trial with a model based on national asthma guidelines and with usual care.

Patients in the two intervention groups will each meet with a care manager for two 1-hour sessions, review their management plan reviewed and modified as necessary using the model for their group assignment, and will be called at three, six, and nine months. Participants, drawn from KP Northwest and Hawaii, will be followed for two years, with outcome data collected at 12 and 24 months.

Primary outcomes of interest are asthma-related quality of life and acute asthma health care. Secondary outcomes will be asthma control, adherence, symptom-free days, lung function, dispensings of asthma medications, satisfaction with asthma care, asthma-related costs, and total asthma-related health care utilization. If effective, this model can be incorporated into clinical practice to improve asthma outcomes and reduce costs.
