Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To address these questions, we propose the study, Comparative Effectiveness of Zolpidem/Trazodone and Cognitive Behavioral Therapy for Insomnia in Rural Adults (COZI). The investigators will use a well-tested Internet version of CBT-I, which is just as effective as in-person CBT-I, but more widely available. The aims of COZI are to: 1: Compare the effectiveness of medication preference (zolpidem or trazodone), CBT-I, and combination treatment for insomnia symptoms over 6 months. 2: Compare the effectiveness of medication preference, CBT-I, and combination treatment for other symptoms and problems, including health-related quality of life, mood, and health outcomes. 3: Compare the side effects of medication preference, CBT-I, and combination treatment. COZI will study 155 patients recruited from 7 health care systems across the country, each of which has established practices in rural areas. Patients will be treated with medication prescribed by their own physician (zolpidem or trazodone), Internet CBT-I, or a combination of the two. The investigators will evaluate treatment effects at 9 weeks, and 6 and 12 months (with limited additional assessments for adverse events and medication use at 1 and 9 months). Our study questions and design reflect early and ongoing engagement of key stakeholders including patients, providers, and payors, who are members of the Study Advisory Committee (SAC). SAC members will work with study investigators to recommend the best strategies for recruiting patients, measuring treatment effects, and disseminating study findings. The SAC will meet quarterly. Patients and other stakeholders have already provided guidance on which treatments are most worth studying, and which symptoms would best reflect the effects of treatment. Patients and other stakeholders will also be part of the Steering Committee, which is the main decision-making group for our study, and which will meet monthly. COZI will lead to answers for patients and providers addressing insomnia; improved health and function for millions of rural Americans; and sustainable changes in how insomnia is treated in rural practices.
