Implementation of CBT-I in Cancer Clinics

Study Overview
=================
Brief Summary
-----------------
Insomnia affects 30-60% of cancer patients, thus making it one of the most common disturbances in this population. When untreated, which is the rule rather than the exception, insomnia often becomes chronic. Chronic insomnia is associated with numerous negative consequences (e.g., increased risk for psychological disorders, health care costs). A large body of evidence supports the efficacy of cognitive-behavioral therapy for insomnia (CBT-I) in cancer patients, but CBT-I is still not offered routinely in cancer clinics. Self-administered CBT-I (e.g., video-based intervention) has been developed to increase patients' access to this treatment. However, results of clinical trials have suggested that these minimal treatments would be better used as a first step of a stepped care model. In stepped care, patients receive only the level of intervention they need. Generally, the entry level is a minimal, less costly, intervention (e.g., self-help intervention) followed by a more intensive form of treatment if needed (if the patient is still symptomatic). The investigators have recently assessed the efficacy of a stepped care model to administer CBT-I in cancer patients, which includes a web-based CBT-I (called Insomnet) followed by up to 3 sessions with a psychotherapist if the patient is still symptomatic. Results of this study suggest that this model of care is non-inferior to a standard face-to-face treatment (Savard, Ivers, et al., in revision), while being more cost-effective. A stepped care CBT-I could therefore be offered in routine cancer care clinics. This project will assess the feasibility and effectiveness of implementing a stepped care CBT-I in real-world cancer clinics, using a non-randomized stepped wedge design to compare the effects of our program (active phase) with a passive phase. The program is called Insomnia in Patients with Cancer - Personalized Treatment (IMPACT). The stepped care CBT-I (active intervention) is being implemented sequentially in the four participating hospitals over a number of equally spaced time periods of 4 months (wedges), for a total of 5 time points, over a period of 20 months.

Design Details

Primary Purpose: Treatment
Intervention Model: Sequential Assignment
Interventional Model Description: The stepped care CBT-I (active intervention) is being implemented sequentially in the four participating hospitals over a number of equally spaced time periods of 4 months (wedges), for a total of 5 time points, over a period of 20 months.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Stepped care CBT-I<br> | Behavioral: Web-based cognitive-behavioral therapy for insomnia (CBT-I)<br>* Each week, the patients first have to read written information on the website (www.insomnet.ca), and then watch a video capsule (duration between 5 and 20 min each). Patients complete their daily sleep diary electronically on the website and the content is interactive. It includes the sending of automated emails to remind participants to complete the treatment tasks and encourage adherence, provision of tailored feedback (e.g., texts, charts) based on the information that they provide in their sleep diary, as well as quizzes with automated correction to reinforce patients' understanding of the content.<br>* Other names: Self-administered;Behavioral: Professionally-administered booster face-to-face CBT-I sessions<br>* Patients who obtain an ISI score of 8 and more after completing the web-based CBT-I are stepped up and offered to receive up to three 50-min booster sessions of CBT-I offered individually by a psychologist (if needed). Remitted patients (good sleepers; ISI score lower than 8) will receive no further treatment.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Implementation (organizational) measures | Referral, enrolment and completion rates to the stepped care CBT-I in each clinical setting. | Passive phase (4 months) vs. active phase (20 months), through study completion, an average of 24 months | 
| 1) Efficiency (patients) measures | Change in Insomnia Severity Index Scores from pre- to post-intervention. The ISI is a 7-item questionnaire designed to evaluate insomnia severity. A score greater than or equal to 8 indicates the presence of insomnia symptoms. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 2) Efficiency (patients) measures | Change in daily sleep diary parameters from pre- to post-intervention: Change in sleep efficiency (SE) index (%) = Total sleep time/total time spent in bed X 100. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 3) Efficiency (patients) measures | Change in daily sleep diary parameters from pre- to post-intervention: Change in sleep onset latency (SOL) = Time to sleep after lights out. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 4) Efficiency (patients) measures | Change in daily sleep diary parameters from pre- to post-intervention: Change in wake after sleep onset (WASO) = Summation of nocturnal awakenings. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 5) Efficiency (patients) measures | Change in daily sleep diary parameters from pre- to post-intervention: Change in total wake time (TWT) = Summation of SOL, WASO, and early morning awakening. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 6) Efficiency (patients) measures | Change in daily sleep diary parameters from pre- to post-intervention: Change in total sleep time (TST) = Time in bed minus total wake time. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 7) Efficiency (patients) measures | Change scores from pre to post-intervention: Hospital Anxiety and Depression Scale (HADS): A 14-item questionnaire comprising 7 items assessing depression and 7 items assessing anxiety. Scores obtained for each subscale range from 0 to 21. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 8) Efficiency (patients) measures | Change scores from pre to post-intervention: Fatigue Symptom Inventory (FSI): A 14-item questionnaire measuring perceived fatigue. Each item is rated on an 11-point Likert scale, ranging from 0 to 10. A higher score indicates a higher level of fatigue or interference or a longer duration of fatigue. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 9) Efficiency (patients) measures | Change scores from pre to post-intervention: The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30): A 30-item questionnaire. Scores are transformed to give a score ranging from 0 to 100. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 10) Efficiency (patients) measures | Change scores from pre to post-intervention: Satisfaction with Life Scale (SWLS): A 5-item questionnaire (Likert scale from 1 to 7) designed to measure global cognitive judgments of satisfaction with one's life. | Pre-treatment and post-treatment (6-8 weeks later) | 
| 1) Fidelity to the treatment protocol (psychologists) | Self-assessed adherence to the CBT-I protocol (%) | Throughout the active phase, up to 20 months | 
| 2) Fidelity to the treatment protocol (psychologists) | Perceived self-efficiency in using CBT-I protocol (%) | Throughout the active phase, up to 20 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

| 2) Possible predictors of a better program uptake | Administrators' and clinicians' attitude towards empirically-based treatments (Evidence-Based Practice Attitudes Scale (EBPAS; 15 items)): Scores obtained range from 0 to 60. | Through study completion, an average of 24 months | 
| 3) Possible predictors of a better program uptake | Stress at work (Workplace Stress Scale (WSS; 8 items)): Scores obtained range from 8 to 40. | Through study completion, an average of 24 months | 
| 4) Possible predictors of a better program uptake | Attitude towards change (Organizational Readiness for Implementing Change (ORIC; 12 items)): Participants rated the hospital's readiness for implementation on 12 items using a 5-point ordinal scale that ranged from disagree (1) to agree (5). | Through study completion, an average of 24 months | 
| 5) Possible predictors of a better program uptake | Clinicians' CBT expertise (number of years of experience with CBT) | Through study completion, an average of 24 months | 
| 6) Possible predictors of a better program uptake | Patients' familiarity with the Internet (Internet Evaluation and Utility Questionnaire (IEUQ; 15 items)): Patients respond to the questions on a 5-point likert scale from not at all (0) to very (4), with 2 open-ended items asking patients to identify most helpful and least helpful parts of the web program. | Pre-treatment and post-treatment (6-8 weeks later) |
