Chronic Insomnia Disorder

The purpose of this study is to compare changes in sleep quality in patients with moderate to severe insomnia, in participants randomized to Cognitive Behavioral Therapy for Insomnia (CBT-I) arm versus those randomized to the SONU Headband Acoustic Resonance Therapy (ART) arm at end of treatment (6 weeks).

The purpose of this study is to assess the relative effectiveness, safety, and durability of the most commonly used prescription (zolpidem, trazodone) and over-the-counter (OTC) (melatonin, diphenhydramine) medications for insomnia, as well as a less commonly used prescription that may have a better risk/benefit profile (doxepin).

Sleep is an essential function for physical and mental health. The mismatch between biological rhythms and the social rhythms of individuals is increasingly common in modern societies. This sleep irregularity can have numerous consequences on mental health, cardiometabolic health, the immune system, functioning, and quality of life. To address the public health issue of sleep irregularity, it is important to be able to obtain a valid and reliable measure. The Sleep Regularity Questionnaire (SRQ) by Dzierzewski et al. addresses this issue, but has never been translated into French. The aim of the study is to translate and validate the French version of the Sleep Regularity Questionnaire.

Insomnia disorder is considered quite common and is recognized as a risk factor for psychiatric disorders. In industrialized countries, chronic insomnia disorder is estimated to affect about 5-10% of the population, with some studies indicating that this rate can reach up to 33% among adults. Research in the Netherlands has shown that insomnia symptoms increase the risk of developing, relapsing, and prolonging mood disorders in men and are associated with recurrent anxiety disorders in women. Without treatment, insomnia disorders are challenging to improve and can impact patients' economic stability and health. Treating insomnia can support recovery and prevent mental disorders, particularly mood disorders. One of the commonly referenced non-pharmacological treatments for insomnia worldwide is Cognitive Behavioral Therapy for Insomnia (CBT-I). This therapy has been recognized by the American College of Physicians as a first-line and highly effective treatment for insomnia. However, it still faces several barriers to widespread application in clinical practice, such as resource constraints and the time commitment required from patients. As a result, some studies abroad have shown that physicians may be reluctant to recommend CBT-I alone, even though it is considered the preferred treatment. To address these challenges, numerous international studies have expanded the range of providers (such as pharmacists and nurses) or adopted shortened versions, such as Brief Behavioral Treatment for Insomnia (BBT-I), in hospitals or community pharmacies. BBT-I has been proven effective among older adults with a 2+2 design (two in-person sessions and two follow-up calls) and among younger adults using an electronic format. This is a brief, evidence-based therapy designed to encourage the application of CBT-I techniques in primary healthcare settings, demonstrating effectiveness when performed by healthcare providers with basic training. A significant advantage of combining CBT-I and BBT-I in treating insomnia is the reduction in medication use. When effectively implemented, it can shorten treatment duration, reduce hospitalization rates, decrease adverse effects from drug interactions, and improve patients' quality of life, ultimately reducing the financial burden on healthcare facilities and improving the quality of medical services. In Vietnam, CBT-I and BBT-I therapies are not yet widely applied or popularized. Based on the current situation and the desire to apply these therapies in treating chronic insomnia patients to improve quality of life and reduce medication costs, in 2023, Nguyen Trai Hospital collaborated with Thong Nhat Hospital and the Saigon Center for Pharmaceutical Science and Technology to conduct a city-level scientific and technological research program on the application of BBT-I in supporting the treatment of chronic insomnia in the elderly. The research developed a "Sleep Support Guide" as a resource for healthcare workers to counsel patients and provide essential information related to insomnia. Results from the study also showed that BBT-I could help improve sleep-related parameters, life quality, and sleep quality among elderly patients. However, the study had some limitations, such as being conducted only on elderly subjects, with a follow-up period of one month post-intervention for sleep parameters and three months for medication usage metrics, without a cost-effectiveness comparison with medication-only treatments. Therefore, further in-depth research with a wider range of subjects and a comparison with standard hospital treatments is necessary for broader application of this method in practice. Objective 1: To investigate the characteristics of chronic insomnia patients receiving medication at Nguyen Trai Hospital in Ho Chi Minh City. Objective 2: To assess the effectiveness of BBT-I in improving sleep quality and quality of life after one and three months compared to non-application in chronic insomnia patients receiving medication at Nguyen Trai Hospital in Ho Chi Minh City. Objective 3: To evaluate the cost-effectiveness of BBT-I in improving sleep quality and quality of life when applied to chronic insomnia patients receiving medication at Nguyen Trai Hospital in Ho Chi Minh City.

Insomnia disorder is characterized by difficulty initiating or maintaining sleep, or early morning awakening accompanied by symptoms such as irritability or fatigue during wakefulness. It is one of the most prevalent health concerns in the population and in clinical practice, with more than one-third of adults experience transient insomnia at some point in their lives. In about 40% of cases, insomnia can develop into a more chronic condition. The COVID-19 pandemic has further aggravated sleep problems, with a reported global prevalence of sleep disturbances reaching 40-49%. The implications of insomnia disorder are substantial, encompassing social, economic, psychological, and physical aspects. Behavioural, cognitive, and pharmacological interventions can all be effective for insomnia. Pharmacological treatment is commonly used but may have drawbacks such as adverse events and inconclusive safety data for certain medications. Many licensed drugs can be effective in the acute treatment of insomnia but are associated with poor tolerability, or information about long-term effects is not available. Alternatively, cognitive behavioural therapy for insomnia (CBT-I), has been recommended as the first-line treatment for chronic insomnia in adults of any age according to the American and European guidelines. But issue of accessibility, compliance/adherence, and moderate response limit the practicality and applicability of CBT-I. Recent evidence suggests that the gut microbiota plays a role in regulating sleep behaviour, both directly and indirectly. This has led to the exploration of gut microbiota modulation as a potential therapy for insomnia. Faecal microbiota transplantation (FMT), which is the infusion of faeces from healthy donors to the gut of affected subjects, has shown impressive therapeutic effects for various diseases. Several real-world studies have demonstrated improvements in symptoms of insomnia disorder following FMT. One previous study also indicated the potential of FMT in alleviating post-COVID insomnia. In this randomised, double-blind, placebo-controlled trial, the investigators aim to assess the efficacy of FMT in improving insomnia disorder. Two groups will be recruited in 1:1 ratio. The intervention group will receive FMT while the control group will receive normal saline as placebo. Both groups will have the same assessments.
