Clinical Trial Summary

The COVID-19 pandemic has resulted in increased workload and concerns about personal and family safety for frontline healthcare workers (HCWs), which can lead to decreased well-being and worsening mental health. Sleep disruption is particularly prevalent among HCWs providing frontline COVID-19 care. It can have direct consequences on their cognitive and emotional functioning, as well as on patient safety. Cognitive Behavioral Therapy for insomnia (CBTi) is a first-line treatment for insomnia. It has been shown to improve sleep health and wellbeing in the general population. However, there are significant barriers to delivering CBTi to frontline HCWs, including limited availability of trained sleep therapists and high costs. To address this, a Canada-wide randomized controlled trial is developed to determine the effectiveness of a digital CBTi program on the sleep health, mental health, wellness, and overall quality of life of frontline HCWs caring for COVID-19 patients. This study may provide an easily accessible and scalable sleep health intervention that can be included as part of a national and global response to the COVID-19 pandemic.

Description:

Sleep disruption is prevalent in frontline healthcare workers (HCWs), of which more than 30% are physicians and nurses. The ongoing COVID-19 crisis has caused decreasing well-being and worsening mental health. Frontline HCWs involved in the management of patients with COVID-19 are nearly 3 times more likely to experience insomnia than anxiety or depression. It can have direct consequences on cognitive and emotional functioning and well-being, which impacts the safety of the patients. Insomnia is a health problem that may be appropriately treated with a less resource-intensive solution. Hypnotics can be considered for short-term use for severe insomnia but it is not free of psychological and/or physical dependence, tolerance, substance misuse, and sleepiness. Therefore, non-pharmacological sleep therapies such as CBTi may be advantageous for improving sleep health, HCW wellness, and in preventing burnout.

Cognitive Behavioral Therapy for insomnia (CBTi) is currently a first-line therapy for adults with sleep disorders including insomnia and other sleep health disruptions. The principles and specific elements of CBTi include stimulus control, sleep hygiene, relaxation therapy, cognitive re-appraisal, and sleep restriction techniques. Delivering CBTi to frontline HCWs is associated with significant barriers including the limited availability of trained sleep therapists and the high cost of receiving face-to-face treatment. Digital CBTi can be easily accessed while maintaining physical distancing, and is less resource intensive than traditional CBTi, while providing symptom self-management and ongoing coach-tailored feedback. Recently, digital CBTi (Sleepio™, Big Health Ltd., London, UK) was made available free of charge to over 1 million frontline COVID-19 HCWs in the United Kingdom's National Health Service for the duration of the COVID-19 pandemic. Indeed, CBTi has already been shown to be effective for patients with insomnia in the general population, but it has not been evaluated amongst HCWs during a pandemic. We propose a national RCT amongst frontline HCWs taking care of patients during the COVID19 era to determine the effect of a digital CBTi program (SleepioTM) on their sleep health, mental health, wellness domains, and overall HRQL.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assessing changes in the nature and severity of insomnia:	Change in score on the Insomnia Severity Index (ISI ) from baseline to 12 weeks. ISI is a 7-item self-report questionnaire that assesses insomnia's nature, severity, and impact. Responses can range from 0 to 4, where higher scores indicate more acute symptoms of insomnia. The score can be classified in the following way: the total score of 0-7 indicates "no clinically significant insomnia," 8-14 means "subthreshold insomnia," 15-21 is "clinical insomnia (moderate severity)," and 22-28 means "clinical insomnia (severe).	12 weeks
Secondary	Sleep Condition Indicator	It is an eight-item rating scale that was developed to screen for insomnia disorder based on DSM-5 criteria. Each item was scored on a 5-point scale (0-4), with lower scores, in the 0-2 range, reflecting putative threshold criteria for insomnia disorder. The possible total score ranges from 0 to 32, with higher values than 16 indicative of better sleep.; The SCI is valid, reliable, and sensitive to change.	12 weeks
Secondary	Patient Reported Outcomes Measurement Information System(PROMIS ) Sleep Disturbance	The PROMIS Sleep Disturbance is an eight-item scale that assesses self-reported perceptions of sleep quality, sleep depth, and restoration associated with sleep. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of sleep disturbance. The raw scores on the 8 items should be summed to obtain a total raw score.	12 weeks
Secondary	Patient Reported Outcomes Measurement Information System(PROMIS ) Sleep Related Impairment	The PROMIS Sleep-Related impairment is an eight-item scale that focuses on self-reported perceptions of alertness, sleepiness, and tiredness during usual waking hours, and the perceived functional impairments during wakefulness associated with sleep problems or impaired alertness. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of sleep disturbance. The raw scores on the 8 items should be summed to obtain a total raw score.	12 weeks
Secondary	Generalized Anxiety Disorder (GAD) 7	The GAD-7 is a valid and efficient tool for screening and assessing the severity of generalized anxiety disorder (GAD) in clinical practice and research. Screening for anxiety disorders, a score of 8 or greater represents a reasonable cut-point for identifying probable cases of generalized anxiety disorder; The following cut-offs correlate with the level of anxiety severity: Score 0-4: Minimal Anxiety; Score 5-9: Mild Anxiety; Score 10-14: Moderate Anxiety; Score greater than 15: Severe Anxiety.	12 weeks
Secondary	Warwick Edinburgh Mental Wellbeing Scale(WEMWBS )	14 items to measure feeling and functional aspects of mental well-being. The WEMWBS is scored by summing the scores for each of the 14 items, which are scored from 1 to 5. The 14-item scale WEMWBS has 5 response categories, summed to provide a single score. Scores range from 14 to 70 and higher scores indicate greater positive mental wellbeing.	12 weeks
Secondary	Work And Social Adjustment Scale (WSAS)	5 items to measure functional impairment attributed to a given disorder.5 items can be scored from 0 to 8. A score of all Items will be summed up. WSAS score >20 reflects severe or worse psychopathology., 10 to 20 reflects significant functional impairment but less severe clinical symptomatology and <10 appears to signify subclinical disorders populations.	12 weeks
Secondary	Impact of Event Scale	22 items to measure current subjective distress due to traumatic life events. The Impact of Event Scale has a scoring range of 0 to 88and a score above 24 is meaningful. A score of 24 or more will have partial PTSD or at least some of the symptoms. A score of 33 and above is a probable diagnosis of PTSD. A score of 37 or more is high enough to suppress the immune system's functioning.	12 weeks
Secondary	Work Productivity and Activity Impairment Questionnaire	It consists of 6 items to measure impairments in works. The sum of specific health problem impairment and impairment due to other health reasons is equal to impairment due to all health reasons. WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes.	12 weeks
Secondary	Maslach Burnout Inventory - Human Service Survey	22 items to measure burnout in medical professionals. Responses are scored on a six-point Likert scale, ranging from 0 = never to 6 = every day, for each subscale, and tabulated into three tiers (low, moderate, or high). Emotional Exhaustion (EE)-9 questions, Depersonalization (DP)-5 questions, and self-perceived lack of Personal Accomplishment (PA)-8 questions.; Based on the reference ranges provided with the MBI-HSS: for EE, low (0-16), moderate (17-26), and high (=27); for DP, low (0-6), moderate (7-12) and high (=13), and finally, for PA, low (=31), moderate (32-38) and high (=39). Burnout was defined by the updated Maslach-recommended criteria of "high EE and high DP" or "high EE and low PA"	12 weeks
Secondary	Patient Global Impression Scale	PGIC is a 7-point scale depicting a patient's rating of overall improvement. Patients rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse." PGIC is commonly used to evaluate the overall improvement or change in symptoms following treatment and is an important indicator of significant change in treatments of chronic pain.	12 weeks
Secondary	Therapy Evaluation Questionnaire	5 items can be scored from 1 to 7. The higher score signifies the greater Depth, Smoothness, and Positivity, of therapy.	12 weeks
Secondary	Acceptability E-scale	Acceptability E-scale has strong psychometric properties and can be useful in assessing the acceptability and usability of computerized health-related programs. The score was rated on five Likert-type scale responses; 1-strongly disagree; 2disagree; 3-not sure; 4-agree; 5-strongly agree. A score of 40 or above indicates that program iss feasible for the use.	12 weeks
Secondary	Sleep Health Disruption	Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of sleep disturbance.	12 weeks
