Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Although much is now known about asthma, and there is effective asthma treatment, only about half of the patients with persistent asthma adhere to their prescribed long-term controller medication. One way to change this might be to involve patients more in decisions about their treatment.
DESIGN NARRATIVE:
Overview and study design This study is designed to evaluate the effectiveness of a model of shared decision-making in improving outcomes in adults aged 18-70 years with suboptimally controlled, mild-moderate persistent asthma. The shared decision-making model (SD) is being compared in a randomized controlled trial with a model based on national asthma guidelines (MG), and with usual care (UC).
Initially, we adapted the model of shared decision-making that has been used successfully in cancer to make it appropriate for a chronic disease (asthma). We will also adapted the KP Asthma Guidelines so that the two models (Management by Guidelines and Shared Decision-Making) take a similar amount of clinician-patient interaction time. We are comparing the two models and usual care in the primary care setting at Kaiser Permanente Northwest and Kaiser Permanente Hawaii in a randomized controlled trial with 24-month follow up. The individual asthma patient will be the unit of randomization.
Interventions were done by a care manager (nurse practitioner or clinical pharmacist) with experience in asthma, and the authority to change medication regimens. Different staff were used for the two intervention groups to minimize contamination between the groups attributable to the intervention. Eligible participants were randomized into the three groups (UC, MG, and SD) on an equal 1:1:1 basis, stratifying on prior health care utilization and within center (KPNW or KPH). All study participants are being followed for 24 months with clinic visits for data collection at 12 months. The MG and SD arms are receiving interim phone calls from the care managers at three, six, and nine months to assess problems with their treatment regimens, discuss changes that may be desired in treatment regimens, and encourage adherence. Different staff are responsible for data collection and intervention.
We will compare the MG and SD models versus usual care (UC vs MG; UC vs SD), and the MG and SD models (MG vs SD).
