Reducing Use of Sleep Medications Assisted by a Digital Insomnia Intervention

Study Overview
=================
Brief Summary
-----------------
Chronic insomnia is one of the most common health problems among Veterans and significantly impacts their health, function, and quality of life. Sedative-hypnotic medications are the most common treatment despite mixed effectiveness and are associated with numerous risks that can further impact Veteran function. An intervention combining evidence-based interventions for deprescribing sedative-hypnotics and behavioral interventions for insomnia can help to optimize sleep and functional outcomes for Veterans with a desire to reduce or stop using these medications. Furthermore, by delivering these interventions through an easy to use and highly accessible digital platform can provide additional benefits to Veterans, especially those with limited time and access to engage in traditional in-person interventions. The Clinician Operated Assistive Sleep Technology (COAST) is an efficient, scalable, and adaptable platform that can help providers to reach more Veterans and provide evidence-based care that translates to improved health and function. Aim 1: To assess the feasibility of recruiting Veterans with chronic sedative-hypnotic use to participate in a 12-week combined deprescribing and CBT-I intervention, delivered through the COAST digital platform. Aim 2: To assess Veteran acceptability and usability of the COAST platform. Aim 3: To assess change in Veteran sleep, sedative-hypnotic use, and function pre- to post-intervention.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Insomnia Severity Index (ISI) Change | Total score (0-28): no insomnia (0-7); sub-threshold (8-14); moderate (15-21); and severe insomnia (22-28). A reduction pre- to post-treatment/follow-up of 8 points (or more) indicate a treatment response and a post-treatment/follow-up score or 7 (or less) indicate remission. | baseline (T0; week 0), post-treatment (T1; week 12), 3 month follow-up (T2; week 24) | 
| Sedative-Hypnotic Medication Use Change | T0, Baseline: medication name, dose, frequency of use (# nights/week) T1, Post-treatment: medication name, dose, frequency of use (# nights/week), >=50% reduction from baseline (yes/no); cessation (yes/no) T2, 3-month follow-up: medication name, dose, frequency of use (# nights/week), >=50% reduction from baseline (yes/no); cessation (yes/no) | baseline (T0; week 0), post-treatment (T1; week 12), 3 month follow-up (T2; week 24) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sleep Diary - Sleep Onset Latency (SOL) Change | The Sleep Diary measures common sleep variables important for tracking and changing sleep behaviors: Sleep Onset Latency (SOL) is the subjective estimate of time it takes to fall asleep after going to bed and turning the lights out (or attempting to go to sleep). SOL is measured in minutes (lower values are better). | baseline (T0; week 0), post-treatment (T1; week 12), 3 month follow-up (T2; week 24) | 
| Sleep Diary - Wake After Sleep Onset (WASO) Change | The Sleep Diary measures common sleep variables important for tracking and changing sleep behaviors: Wake After Sleep Onset (WASO) is the subjective estimate of time awake in the middle of the night, after falling asleep and before final rise time/out of bed. WASO is measured in minutes (lower values are better). | baseline (T0; week 0), post-treatment (T1; week 12), 3 month follow-up (T2; week 24) | 
| Sleep Diary - Sleep Efficiency Change | The Sleep Diary measures common sleep variables important for tracking and changing sleep behaviors: Sleep Efficiency (SE) = (total sleep time [TST] / time in bed [TIB]) x 100. SE is measured as a percentage (range 0-100%; higher values are better). | baseline (T0; week 0), post-treatment (T1; week 12), 3 month follow-up (T2; week 24) | 
| Patient-Reported Outcomes Measurement Information System Adult Profile (PROMIS 29+2) Change | The PROMIS 29+2 includes measures of Physical Function, Social Roles, Anxiety, Depression, Fatigue, Sleep Disturbance, Pain Interference, Pain Intensity, and Cognitive Function. Each construct is scored individually (4 items, range 4-20) except Cognitive Function (2 items, range 2-10). A higher PROMIS T-score represents more of the concept being measured. For negatively-worded concepts like Anxiety, a T-score of 60 is one SD worse than average. By comparison, an Anxiety T-score of 40 is one SD better than average. However, for positively-worded concepts like Physical Function-Mobility, a T score of 60 is one SD better than average while a T-score of 40 is one SD worse than average. When all constructs are scored together, a preference score is calculated, representing health-related quality of life ranging from 0 (as bad as dead) to 1 (perfect or ideal health). | baseline (T0; week 0), post-treatment (T1; week 12), 3 month follow-up (T2; week 24) |
