Not Applicable

• Conditions: Insomnia Related to Osteoarthritis Pain

• Registration Number: NCT02946957
• Lead Sponsor: University of Washington

Brief Summary

Osteoarthritis (OA) pain affects 50 percent of older adults, more than half of whom also experience significant sleep disturbance. This randomized trial will determine whether a telephone-based cognitive behavioral treatment targeting insomnia in older adults with chronic severe OA-related insomnia and pain results in substantially greater reductions in insomnia severity and in related improvements in pain, fatigue, mood, quality of life and healthcare costs compared to telephone-delivered education (attention control) about insomnia. The trial will test an intervention that if demonstrated to have long term efficacy is scalable and has the potential for wide-scale deployment in healthcare systems.

Detailed Description

Twenty-five percent of older adults experience significant osteoarthritis (OA)-related comorbid sleep disturbance. Insomnia is associated with substantial negative effects on function, mood, and medical resource utilization. Cognitive behavioral therapy for insomnia (CBT-I) is evidence based and has been shown to be efficacious in populations with a variety of comorbid conditions including OA-related chronic pain. However, in-person CBT interventions are unlikely to be widely deployable in healthcare systems. Telephone delivery has the advantage of giving patients access to personalized, efficacious CBT-I interventions from home, increasing generalizability, and outreach to minority, rural, and other underserved populations. Older (60+ yrs) primary care patients across Washington State will be screened for severe persistent OA-related insomnia and pain. Two hundred and seventy patients will be randomized to either CBT-I or an education only attention control (EOC). Each treatment will consist of six 20-30 minute telephone-based sessions over an eight week period. Pre-treatment, post-treatment (2 months and 12 month) assessments will include measures of sleep, pain, fatigue, mood, and quality of life. A cost effectiveness evaluation of the intervention will also be conducted. The proposed research will determine if telephone CBT-I improves OA insomnia and associated outcomes in a state-wide primary care population of older adults, and inform policy decisions about widespread dissemination of telephone CBT-I in this and related patient populations.

Arm && Interventions

Group	Intervention	Description
Education Control	Education Only Control	Education Only Control is delivered by trained sleep therapists in six telephone sessions.
Cognitive Behavioral Therapy	Cognitive Behavior Therapy for Insomnia	Cognitive Behavioral Therapy for Insomnia is delivered by trained sleep therapists in six telephone sessions.

Primary Outcome Measures

Name	Time	Method
Insomnia Severity Index (ISI)	12 months post baseline	A 7-item questionnaire that is a global measure of perceived insomnia severity. Items use a 5-point scale for total scores of 0-28, with \>15 considered moderate severity.

Secondary Outcome Measures

Name	Time	Method
Insomnia Severity Index (ISI)	2 months post baseline	A 7-item questionnaire that is a global measure of perceived insomnia severity.Items use a 5-point scale for total scores of 0-28, with \>15 considered moderate severity.
Pittsburgh Sleep Quality Index (PSQI)	12 months post baseline	Self-rating of overall sleep quality and disturbances using 7 sleep components. PSQI global \>5 is highly sensitive and specific for distinguishing good and poor sleepers.
Brief Pain Inventory-short form (BPI-sf)	12 months post baseline	A questionnaire to assess pain intensity and interference with activities. The BPI-sf rates pain intensity (4 items) and interference (7 items) from 0 to 10 and is validated for use in clinical trials with OA pain patients.
Flinders Fatigue Scale (FFS)	12 months post baseline	A 7-item self-report questionnaire to measure fatigue level in a variety of situations.
Patient Health Questionnaire (PHQ-8)	12 months post baseline	4-point scale rates frequency of occurrence of 8 depressive symptoms.
Sleep Hygiene Index (SHI)	12 months post baseline	A 13-item scale that rates how often participants engage in specific sleep hygiene related behaviors, including continued adherence to CBT-I recommendations over time.
EuroQoL 5D (EQ-5D)	12 months post baseline	Rates health status on five dimensions and overall health status from 0 to 100. The most widely used measure in clinical trials assessing general quality of life of OA patients.
Western Ontario and McMaster Universities Arthritis Index (WOMAC)	12 months post baseline	A 24-item questionnaire rating pain, stiffness, and physical functioning in everyday activities. It is the most widely used condition-specific quality of life measure for arthritis cost-effectiveness studies.
Use of sleep and pain medications	Baseline through 24 months	NSAID, analgesic, sedative, and anti-depressant medication use.
Outpatient visits	Baseline through 24 months	The number of visits for OA, for sleep problems, and for visits irrespective of associated diagnosis.
Health care costs	Baseline through 24 months	The Group Health cost database will be used to estimate costs (from study entry to 24 months post enrollment) of ambulatory healthcare for all conditions, arthritis and sleep problems, and inpatient care.
