RESUMO
Daridorexant is a dual orexin receptor antagonist for the treatment of insomnia. We report results from the first two randomised, double-blind clinical studies of daridorexant in Japanese subjects. In the Phase 1 study, daridorexant (10, 25, 50 mg) or placebo were administered in the morning for 4 days in 24 young (mean age 26.9 years) and 24 older (mean age 69.7 years) healthy Japanese adults. Daridorexant reached a peak plasma concentration within 1.0 h across every dose and age group. For all doses, the mean plasma concentration of daridorexant showed a similar change between the age groups. Exposure parameters increased dose-dependently with minimal/no accumulation upon repeated dosing. The terminal half-life was ~8 h. In the Phase 2, four-period, four-way crossover study, 47 Japanese subjects (mean age 50.4 years) with insomnia disorder were randomised to receive four treatments (daridorexant 10, 25, 50 mg, placebo) during four treatment periods, each consisting of two treatment nights (5-12 day washout between treatment periods). Subjects continued their fourth treatment for 12 further days. A statistically significant dose-response relationship (multiple-comparison procedure-modelling, p < 0.0001) was found in the reduction of polysomnography-measured wake after sleep onset (WASO; primary endpoint) and latency to persistent sleep (secondary endpoint) from baseline to days 1/2. Statistically significant dose-response relationships were also observed for secondary subjective endpoints from baseline to days 1/2 (sWASO, latency to sleep onset). All daridorexant doses were well tolerated, with no treatment discontinuations and no next-morning residual effects. These results supported further investigation of daridorexant in Japanese patients with insomnia disorder.
RESUMO
BACKGROUND: Insomnia is more common as people age. Several common hypnotics used to treat insomnia often do not adequately alleviate sleep issues in older adults and may be associated with negative residual effects such as an increased risk of falls, cognitive impairment, automobile accidents, and lack of response to auditory stimuli. The objective of these analyses of three clinical studies was to investigate the efficacy and safety of the dual orexin-receptor antagonist lemborexant (LEM) in older adults. METHODS: Study E2006-G000-304 (Study 304; NCT02783729) was a randomized, double-blind, placebo (PBO)-controlled, active-comparator trial where subjects with insomnia disorder received LEM 5 mg (LEM5), LEM 10 mg (LEM10), zolpidem tartrate extended-release 6.25 mg (ZOL), or PBO for 30 days. In crossover Study E2006-E044-106 (Study 106; NCT02583451), healthy subjects (good sleepers) received LEM 2.5 mg, LEM5, LEM10, or PBO for eight nights or zopiclone on days 1 and 8 (and PBO on days 2-7). In crossover Study E2006-A001-108 (Study 108; NCT03008447), healthy subjects received a single dose of LEM5, LEM10, PBO, or ZOL. Sleep assessments included polysomnography-based latency to persistent sleep (LPS), wake after sleep onset (WASO), WASO in the second half of the night (WASO2H), sleep efficiency, postural stability, middle-of-the-night and next-day cognitive performance, middle-of-the-night auditory awakening threshold and return-to-sleep latency, and driving performance. RESULTS: Overall, 453 of 1006 (45%; Study 304), 24 of 48 (50%; Study 106), and 28 of 56 (50%; Study 108) subjects were aged ≥ 65 years. In Study 304, LEM decreased (improved) LPS, WASO, and WASO2H from baseline more than ZOL and PBO; subjects treated with LEM had greater increases in sleep efficiency (improved) than with ZOL or PBO. In both Studies 304 and 108, postural stability was not impaired at waketime in subjects who received LEM compared with PBO. At waketime, LEM did not impair memory compared with PBO. In Study 108, following middle-of-the-night awakening, LEM and ZOL did not affect subjects' ability to awaken to auditory stimuli; LEM did not affect tests of memory and attention. In Study 106, LEM did not impair next-day driving performance in healthy elderly compared with PBO. LEM was well tolerated in subjects aged ≥ 65 years. CONCLUSIONS: LEM provided benefits on sleep variables without next-morning residual effects in subjects aged ≥ 65 years, supporting LEM as a treatment option for older adults with insomnia. TRIAL REGISTRATION NUMBERS AND DATES OF REGISTRATION: Study 304: ClinicalTrials.gov identifier, NCT02783729, date of registration, 26 May 2016. Study 106: ClinicalTrials.gov identifier, NCT02583451, date of registration, 22 October 2015. Study 108: ClinicalTrials.gov identifier, NCT03008447, date of registration, 2 January 2017.
The prevalence of insomnia increases with age; however, some hypnotics used for treating insomnia do not adequately resolve sleep problems in older adults and may be associated with adverse residual effects. Specifically, some hypnotics pose safety concerns in this population of patients who are generally more vulnerable to treatment-related effects, including increasing the risk of falls, risks of cognitive impairment, automobile accidents, and unresponsiveness to auditory stimuli. Safer and more effective insomnia medications are needed to reduce sleep problems with improved side-effect profiles. This analysis of lemborexant clinical studies conducted in adult subjects at least 65 years old found the drug to be effective without impairing memory, attention or balance the following day compared with placebo. These subjects were normal sleepers (for age) or had insomnia disorder. Furthermore, lemborexant was not associated with impaired ability to drive the next morning or awaken to loud middle-of-the-night sounds. Lemborexant was well tolerated in these older adults, similar to findings for adults aged at least 18 years. These findings indicate that lemborexant may be an appropriate treatment option for insomnia in older adults.
RESUMO
BACKGROUND: When considering changing hypnotic pharmacotherapy, lemborexant has attracted attention as a candidate due to its effectiveness and safety profile. However, few studies have investigated switching patterns in clinical practice. RESEARCH DESIGN AND METHODS: We conducted a retrospective cohort study using a nationwide claims database. Patients prescribed a single hypnotic who either subsequently switched to (switching cohort) or were additionally prescribed (add-on cohort) lemborexant between July 2020 and December 2021 were identified. Proportion of successful switching was defined as remaining on lemborexant alone or without any hypnotic at 6 months after lemborexant initiation. RESULTS: The success proportion was 70.1% in the switching cohort (n = 4,861) and 38.6% in the add-on cohort (n = 9,423). In the add-on cohort, the success proportion was lower in patients with a hypnotic history of ≥180 days (31.4%) and in patients whose prescribed hypnotic was a benzodiazepine or non-benzodiazepine (31.5% and 37.6%, respectively). CONCLUSION: The proportion of successful switching was higher in patients who switched to lemborexant than in those who added lemborexant as a concomitant treatment. The lower success proportion in the add-on cohort might be related to clinically more severe insomnia, and/or a concomitant prescription of benzodiazepine or non-benzodiazepine, from which discontinuation may be challenging.
RESUMO
Introduction: Guidelines for various psychiatric disorders recommend short-term use of benzodiazepine anxiolytic monotherapy in few cases. Contrarily, benzodiazepine anxiolytic polypharmacy (BAP) is not recommended in any case. However, BAP is often used in real world. Therefore, this study aimed to determine the association between BAP and concomitant use of psychotropic medications. Method: This retrospective cross-sectional study used claims data from the Japan Medical Data Center. Medical information of health insurance subscribers treated with benzodiazepine anxiolytics in June 2019 was extracted. Prescription of two or more benzodiazepine anxiolytics was defined as BAP. Binary logistic regression analysis was performed to investigate the factors associated with BAP, using age group, sex, type of subscriber, and number of concomitant hypnotics, antidepressants, and antipsychotics (none, one, and two or more) as covariates. Result: The eligible participants were 104,796 adults who were prescribed benzodiazepine anxiolytics. Among them, 12.6% were prescribed two or more drugs. Logistic regression analysis revealed that BAP was significantly associated with those who received hypnotic monotherapy (adjusted odds ratio [aOR]: 1.04, 95% confidence interval [CI]: 1.001-1.09, p=0.04), antidepressant monotherapy and polypharmacy (aOR: 1.57, 95% CI: 1.51-1.63, p<0.001 and aOR: 1.98, 95% CI: 1.88-2.09, p<0.001, respectively), and antipsychotic monotherapy and polypharmacy (aOR: 1.12, 95% CI: 1.07-1.19, p<0.001 and aOR: 1.41, 95% CI: 1.30-1.54, p<0.001, respectively). Conversely, lower BAP was associated with those who received hypnotic polypharmacy (aOR: 0.86, 95% CI: 0.81-0.91, p<0.001). Discussion: This study showed that the greater the number of concomitant antidepressants and antipsychotics, the greater the association with BAP. Since combination therapy with antidepressants or antipsychotics is generally not recommended, patients receiving combination therapy with these medications may be resistant to pharmacotherapy. Therefore, implementing the recommended non-pharmacological treatments may reduce BAP.
RESUMO
Previous studies on sleep state misperception have objectively evaluated sleep status in special environments using polysomnography. There is a paucity of data from studies that evaluated habitual sleep status in home environments. The present study aimed to investigate sleep state misperception in the home environment of patients with chronic insomnia using a lumbar-worn actigraphy to identify sleep habits associated with sleep state misperception severity. Thirty-one patients and 42 healthy volunteers were included in the insomnia and non-insomnia group, respectively. Participants recorded subjective assessments in sleep diaries, objective assessments with an actigraphy worn for 14 days, and self-assessments using questionnaires. Both groups had similar objective sleep ratings; however, insomnia group had significantly worse subjective ratings (total sleep time, wake after sleep onset, and sleep onset latency). A significant correlation was found between subjective and objective total sleep time scores in non-insomnia group but not in insomnia group. Insomnia group had earlier bedtimes, significantly longer bedtimes, and impaired daytime functioning (Sheehan Disability Scale score); additionally, they underestimated their total sleep time, particularly with earlier bedtimes and longer laying durations. Monitoring the sleep status and habits of individuals in home environments could be instrumental in identifying key points for targeted interventions on sleep hygiene and cognitive behavioral therapy for insomnia.

BACKGROUND: It is unclear how primary care physicians manage insomnia after the introduction of novel hypnotics such as orexin receptor antagonists and melatonin receptor agonists. This Web-based questionnaire survey aimed to examine treatment strategies for insomnia in Japanese primary care practice. METHODS: One-hundred-and-seventeen primary care physicians were surveyed on the familiarity of each management option for insomnia on a binary response scale (0 = "unfamiliar"; 1 = "familiar") and how they managed insomnia using a nine-point Likert scale (1 = "I never prescribe/perform it"; 9 = "I often prescribe/perform it"). Physicians who were unfamiliar with a management option were deemed to have never prescribed or performed it. RESULTS: Regarding medication, most physicians were familiar with novel hypnotics. Suvorexant was the most used hypnotic, followed by lemborexant and ramelteon. These novel hypnotics averaged 4.8-5.4 points and 4.0-4.7 points for sleep onset and sleep maintenance insomnia, respectively. By contrast, most benzodiazepines were seldom used below two points. Regarding psychotherapy, only approximately 40% of the physicians were familiar with cognitive behavioral therapy for insomnia (CBT-I) and they rarely implemented it, at an average of 1.5-1.6 points. More physicians were familiar with single-component psychotherapies (i.e., relaxation, sleep restriction therapy, and stimulus control) compared to CBT-I, and 48-74% of them implemented it slightly more often, with scores ranging from 2.6 to 3.4 points. CONCLUSION: This study suggests that Japanese primary care physicians seldom use CBT-I to treat insomnia. In addition, they use novel sleep medications more frequently than benzodiazepines in terms of pharmacotherapy. The use and availability of CBT-I in Japanese primary care might be facilitated by: educating primary care physicians, implementing brief or digital CBT-I, and/or developing collaborations between primary care physicians and CBT-I specialists.

BACKGROUND AND OBJECTIVE: A prospective, postmarketing observational study was conducted to evaluate the safety and efficacy of lemborexant (LEM) tablets in daily clinical practice in Japan. No other studies of a similar size have been conducted since the marketing approval of LEM, making this the first report of its kind. METHODS: Insomnia patients (n = 550) administered LEM (5-10 mg daily) for the first time were enrolled. Adverse events were collected for target events (somnolence, parasomnia, narcolepsy and associated conditions, suicidal ideation and suicidal behavior). Overall improvement of insomnia symptoms was assessed by the investigator based on the patient's complaint. Subjective sleep onset latency (sSOL) and subjective total sleep time (sTST) were investigated as sleep parameters. RESULTS: A case report form was obtained from 539 patients. The incidence of adverse drug reactions (ADRs) was 7.65% for somnolence, 1.76% for nightmares, 0.59% for abnormal dreams, and 0.20% for sleep paralysis. No serious ADRs or ADRs related to suicidal ideation or suicidal behavior were observed. The efficacy rate at the final evaluation was 80.83%. Decreased sSOL and increased sTST were observed as assessed starting from Week 8 of treatment. CONCLUSION: Based on the results of this study, the safety result was consistent with the safety profile described in the current package insert. Efficacy results also indicated that LEM is clinically useful.

BACKGROUND: Pharmacologic treatments are available to treat insomnia, a common and burdensome sleep disorder, but may be contraindicated in older adults who are prone to side effects from sleep-promoting drugs. These analyses of sleep diary data from Study E2006-G000-303 (Study 303) investigated the benefits of lemborexant 5 mg (LEM5) and 10 mg (LEM10) in the subgroup age ≥ 65 years with insomnia. METHOD: Study 303, a 12-month, double-blind study of LEM5 and LEM10 in adults (age ≥ 18 years) with insomnia disorder (sleep onset and/or maintenance difficulties) assessed subject-reported (subjective) sleep-onset latency (sSOL), sleep efficiency (sSE), wake after sleep onset (sWASO), and total sleep time (sTST). Morning sleepiness/alertness, insomnia severity (Insomnia Severity Index [ISI]), fatigue (Fatigue Severity Scale [FSS]), perceptions of sleep-related medication effects (Patient Global Impression-Insomnia [PGI-I] questionnaire), and safety were also evaluated. RESULTS: In this subgroup of older adults (≥ 65 years; n = 262), there were significantly larger changes from baseline for sSOL, sSE, sTST, and sWASO with LEM5 and LEM10 versus placebo through month 6 (except sWASO month 1), indicating improvement; these improvements were sustained through month 12. Subject-reported increases in morning alertness were significantly greater with one or both LEM doses versus placebo through month 6 and sustained through month 12. There were significantly larger ISI total and daytime functioning score decreases (improvement) from baseline with LEM versus placebo at months 1, 3, and 6 (total score: both doses; daytime functioning: LEM5 month 1 and both doses months 3 and 6) and decreases from baseline FSS at months 1 and 3 (LEM5) and month 6 (both doses), sustained to month 12. Compared with placebo, more subjects reported that LEM (both doses) positively impacted ability to sleep, time to fall asleep, and TST through month 6, sustained to month 12, with no rebound after drug withdrawal. LEM was well tolerated to month 12; mild somnolence was the most common treatment-emergent adverse event. CONCLUSIONS: Improvements in subject-reported efficacy in LEM-treated adults age ≥ 65 years with insomnia were observed as early as the first week of treatment and sustained through end of month 12. LEM was well tolerated. CLINICAL TRIALS REGISTRATION: ClinicalTrials.gov identifier NCT02952820: E2006-G000-303; Study 303; SUNRISE-2 (First posted: October 2016); EudraCT 2015-001463-39 (First posted: November 2016).
Insomnia is a common sleep disorder associated with significant difficulties, particularly in older adults. Although there are many drug treatments available, some are associated with the important risk of side effects and may not adequately treat sleep maintenance (ability to stay asleep), which is a frequent sleep complaint in older people. Lemborexant has been approved in multiple countries for the treatment of adults with insomnia based on studies that show lemborexant improved adults' ability to fall asleep and stay asleep and is well tolerated. To examine the long-term benefit of lemborexant, we investigated subject-reported benefits and safety of lemborexant in older (≥ 65 years) adults who participated in a 1-year study. The results showed that within the first few days of taking lemborexant, and lasting through 12 months of treatment, nightly lemborexant improved nighttime sleep (that is, it reduced the time it took to fall asleep, reduced the time awake during the night, and increased total sleep time) more than placebo. Morning alertness improved more in older adults who took lemborexant compared with placebo. In addition, those who took lemborexant also reported that their insomnia symptoms were less severe and they had less fatigue compared with placebo. Lemborexant was well tolerated in older adults. These results suggest that lemborexant may be a good option for older adults with insomnia disorder.
RESUMO
Importance: Although insomnia guidelines recommend the use of several individual hypnotics, the most useful hypnotic for treating insomnia in a clinical setting remains unclear. Objective: To determine which guideline-recommended hypnotics have lower risks of monotherapy failure and which hypnotics have a higher risk of long-term prescription for insomnia treatment. Design, Setting, and Participants: This retrospective observational cohort study used data from the Japan Medical Data Center Claims Database from April 1, 2005, to March 31, 2021. Participants included adults whose first prescribed pharmaceutical treatment for insomnia was guideline-recommended hypnotic monotherapy. Data were analyzed from December 24, 2022, to September 26, 2023. Exposures: Suvorexant, ramelteon, eszopiclone, zolpidem, and triazolam monotherapy. Main Outcomes and Measures: The primary outcome was monotherapy failure, defined as a change in hypnotic or having an additional hypnotic prescribed for insomnia within 6 months of the first prescription of a guideline-recommended hypnotic monotherapy. The secondary outcome was monotherapy discontinuation, defined as no prescription of any hypnotic for 2 consecutive months within 6 months after prescribing a guideline-recommended hypnotic in patients for whom monotherapy did not fail. Monotherapy failure and discontinuation were compared using Cox proportional hazards and logistic regression models, respectively. Results: The study included 239â¯568 adults (median age, 45 [IQR, 34-55] years; 50.2% women) whose first prescription for insomnia was guideline-recommended hypnotic monotherapy. During the 6-month follow-up period, 24â¯778 patients (10.3%) experienced failure of monotherapy with a guideline-recommended hypnotic. In comparison with eszopiclone, there were more cases of monotherapy failure for ramelteon (adjusted hazard ratio [AHR], 1.23 [95% CI], 1.17-1.30; P < .001), fewer cases for zolpidem (AHR, 0.84 [95% CI, 0.81-0.87]; P < .001) and triazolam (AHR, 0.82 [95% CI, 0.78-0.87]; P < .001), and no significant difference between suvorexant and eszopiclone. Among those without monotherapy failure, monotherapy was discontinued in 84.6% of patients, with more discontinuations for ramelteon (adjusted odds ratio [AOR], 1.31 [95% CI, 1.24-1.40]; P < .001) and suvorexant (AOR, 1.20 [95% CI, 1.15-1.26]; P < .001) than for eszopiclone and no significant difference between zolpidem or triazolam and eszopiclone. Conclusions and Relevance: Due to uncontrolled confounding factors in this cohort study, no conclusions regarding the pharmacologic properties of guideline-recommended hypnotics can be drawn based on these results. Further studies accounting for confounding factors, including diagnoses of chronic vs acute insomnia disorder, insomnia and psychiatric symptom severity, and physician attitudes toward hypnotic prescription, are needed.

RATIONALE: The efficacy and safety of antidepressant augmentation therapy with aripiprazole (AATA) has been established; however, the ongoing effects of continuing aripiprazole after remission remain unclear because no studies have examined this issue. OBJECTIVES: We aimed to explore the effect of AATA discontinuation on the major depressive disorder (MDD) recurrence risk in patients with remitted MDD after AATA. METHODS: This 24-week, multicenter, placebo-controlled, double-blind, randomized trial evaluated recurrence risk in patients with MDD who achieved remission with AATA. Differences in MDD recurrence, as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, between the two groups were compared using survival analysis. The differences in depressive symptom severity and social functioning between the two groups were compared using a mixed model with repeated measures. Extrapyramidal symptoms and akathisia were also assessed. RESULTS: Twenty-three participants were randomized and treated. Two patients in each group experienced recurrence during the study. Kaplan-Meier analysis with Log-rank comparison showed no difference in recurrence between groups (p = 0.642). No significant difference in interactions between group and period was observed in the 17-item Hamilton depression rating scale (p = 0.492) or the Social and Occupational Functioning Assessment Scale (p = 0.638). No patients developed extrapyramidal symptoms or akathisia. CONCLUSIONS: Definitive conclusions could not be drawn owing to the small sample size. This study represents a starting point for investigating the safety of aripiprazole discontinuation on recurrence in patients with MDD who have achieved remission with AATA. Future studies with appropriate sample sizes calculated based on this study are needed.

Object: Real-world data from wearable devices has the potential to understand mental health status in everyday life. We aimed to investigate the feasibility of estimating mental health status using a wrist-worn wearable device (Fitbit Sense) that measures movement using a 3D accelerometer and optical pulse photoplethysmography (PPG). Methods: Participants were 110 patients with mental illnesses from different diagnostic groups. The study was undertaken between 1 October 2020 and 31 March 2021. Participants wore a Fitbit Sense on their wrist and also completed the State-Trait Anxiety Inventory (STAI), Positive and Negative Affect Schedule (PANAS), and EuroQol 5 dimensions 5-level (EQ-5D-5L) during the study period. To determine heart rate (HR) variability (HRV), we calculated the sdnn (standard deviation of the normal-to-normal interval), coefficient of variation of R-R intervals, and mean HR separately for each sleep stage and the daytime. The association between mental health status and HR and HRV was analyzed. Results: The following significant correlations were found in the wake after sleep onset stage within 3 days of mental health status assessment: sdnn, HR and STAI scores, HR and PANAS scores, HR and EQ-5D-5L scores. The association between mental health status and HR and HRV was stronger the closer the temporal distance between mental health status assessment and HR measurement. Conclusion: A wrist-worn wearable device that measures PPG signals was feasible for use with patients with mental illness. Resting state HR and HRV could be used as an objective assessment of mental health status within a few days of measurement.
RESUMO
AIM: Continued antipsychotic treatment is the key to preventing relapse. Maintenance antipsychotic monotherapy and optimal dose use are recommended for individuals with stable schizophrenia because of their undesirable effects. Decision aids (DAs) are clinical conversation tools that facilitate shared decision-making (SDM) between patients and health-care providers. This study aimed to describe the development process and results of acceptability testing of a DA for individuals with stable schizophrenia, considering (i) whether to continue high-dose antipsychotics or reduce to the standard dose and (ii) whether to continue two antipsychotics or shift to monotherapy. METHODS: A DA was developed according to the guidelines for the appropriate use of psychotropic medications and International Patient Decision Aid Standards (IPDAS). First, a DA prototype was developed based on a previous systematic review and meta-analysis conducted for identifying the effects of continuing or reducing antipsychotic treatment. Second, mixed-method survey was performed among individuals with schizophrenia and health-care providers to modify and finalize the DA. RESULTS: The DA consisted of an explanation of schizophrenia, options to continue high-dose antipsychotics or reduce to the standard dose, options to continue two antipsychotics or shift to monotherapy, pros and cons of each option, and a value-clarification worksheet for each option. The patients (n = 20) reported acceptable language use (75%), adequate information (75%), and well-balanced presentation (79%). Health-care providers (n = 20) also provided favorable overall feedback. The final DA covered six IPDAS qualifying criteria. CONCLUSION: A DA was successfully developed for schizophrenia, considering whether to reduce antipsychotics, which can be used in the SDM process.

Previously, insomnia and adverse lifestyle were prevalent among truck drivers, but the association between the two remains unknown in this particular occupational cohort. This study aimed to examine the relationship between insomnia and lifestyle-related diseases among truck drivers. We investigated 875 male truck drivers of the Japan Truck Association, Akita branch, as of July 2020. The definition of insomnia was based on the International Classification of Sleep Disorders, Third Edition (ICSD-3). Data from a self-administered questionnaire were merged with health records and health insurance claims data of 2020. In total, 40.1% had either one of the lifestyle-related diseases including hypertension (29.7%), diabetes mellitus (11.7%), and dyslipidemia (24.8%), whereas according to ICSD-3, 13.2% had insomnia. Multivariate logistic regression models demonstrated that individuals with insomnia had approximately 2-fold increased risk of having at least one lifestyle-related disease (p < 0.001), hypertension (p = 0.0027), diabetes mellitus (p = 0.0654) and dyslipidemia (p < 0.001). Occupational characteristics including daily driving hours, driving distance, and travel days were not associated with any lifestyle-related diseases except for an association between short-haul and at least one disease. In conclusion, insomnia is significantly associated with increased risks of lifestyle-related diseases among male truck drivers in Japan.

Aim: We aimed to develop a decision aid (DA) for individuals with anxiety disorders who consider tapering benzodiazepine (BZD) anxiolytics, and if tapering, tapering BZD anxiolytics with or without cognitive behavioral therapy (CBT) for anxiety. We also assessed its acceptability among stakeholders. Methods: First, we conducted a literature review regarding anxiety disorders to determine treatment options. We cited the results of the systematic review and meta-analysis, which we conducted previously, to describe the related outcomes of two options: tapering BZD anxiolytics with CBT and tapering BZD anxiolytics without CBT. Second, we developed a DA prototype in accordance with the International Patient Decision Aid Standards. We carried out a mixed methods survey to assess the acceptability among stakeholders including those with anxiety disorders and healthcare providers. Results: Our DA provided information such as explanation of anxiety disorders, options of tapering or not tapering BZD anxiolytics (if tapering, the options of tapering BZD anxiolytics with or without CBT) for anxiety disorder, benefits and risks of each option, and a worksheet for value clarification. For patients (n = 21), the DA appeared to be acceptable language (86%), adequate information (81%), and well-balanced presentation (86%). The developed DA was also acceptable for healthcare providers (n = 10). Conclusion: We successfully created a DA for individuals with anxiety disorders who consider tapering BZD anxiolytics, which was acceptable for both patients and healthcare providers. Our DA was designed to assist patients and healthcare providers to involve decision-making about whether to taper BZD anxiolytics or not.
RESUMO
Purpose: Sleep-tracking devices have performed well in recent studies that evaluated their use in healthy adults by comparing them with the gold standard sleep assessment technique, polysomnography (PSG). These devices have not been validated for use in patients with psychiatric disorders. Therefore, we tested the performance of three sleep-tracking devices against PSG in patients with psychiatric disorders. Patients and methods: In total, 52 patients (32 women; 48.1 ± 17.2 years, mean ± SD; 18 patients diagnosed with schizophrenia, 19 with depressive disorder, 3 with bipolar disorder, and 12 with sleep disorder cases) were tested in a sleep laboratory with PSG, along with portable electroencephalography (EEG) device (Sleepgraph), actigraphy (MTN-220/221) and consumer sleep-tracking device (Fitbit Sense). Results: Epoch-by-epoch sensitivity (for sleep) and specificity (for wake), respectively, were as follows: Sleepgraph (0.95, 0.76), Fitbit Sense (0.95, 0.45) and MTN-220/221 (0.93, 0.40). Portable EEG (Sleepgraph) had the best sleep stage-tracking performance. Sleep-wake summary metrics demonstrated lower performance on poor sleep (ice, shorter total sleep time, lower sleep efficiency, longer sleep latency, longer wake after sleep onset). Conclusion: Devices demonstrated similar sleep-wake detecting performance as compared with previous studies that evaluated sleep in healthy adults. Consumer sleep device may exhibit poor sleep stage-tracking performance in patients with psychiatric disorders due to factors that affect the sleep determination algorithm, such as changes in autonomic nervous system activity. However, Sleepgraph, a portable EEG device, demonstrated higher performance in mental disorders than the Fitbit Sense and actigraphy.
RESUMO
Purpose: There is a lack of evidence regarding answers for clinical questions about treating insomnia disorder. This study aimed to answer the following clinical questions: (1) how to use each hypnotic and non-pharmacological treatment differently depending on clinical situations and (2) how to reduce or stop benzodiazepine hypnotics using alternative pharmacological and non-pharmacological treatments. Methods: Experts were asked to evaluate treatment choices based on 10 clinical questions about insomnia disorder using a nine-point Likert scale (1 = "disagree" to 9 = "agree"). The responses of 196 experts were collected, and the answers were categorized into first-, second-, and third-line recommendations. Results: The primary pharmacological treatment, lemborexant (7.3 ± 2.0), was categorized as a first-line recommendation for sleep initiation insomnia, and lemborexant (7.3 ± 1.8) and suvorexant (6.8 ± 1.8) were categorized as the first-line recommendations for sleep maintenance insomnia. Regarding non-pharmacological treatments for primary treatment, sleep hygiene education was categorized as the first-line recommendation for both sleep initiation (8.4 ± 1.1) and maintenance insomnia (8.1 ± 1.5), while multicomponent cognitive behavioral therapy for insomnia was categorized as the second-line treatment for both sleep initiation (5.6 ± 2.3) and maintenance insomnia (5.7 ± 2.4). When reducing or discontinuing benzodiazepine hypnotics by switching to other medications, lemborexant (7.5 ± 1.8) and suvorexant (6.9 ± 1.9) were categorized as first-line recommendations. Conclusion: Expert consensus indicates that orexin receptor antagonists and sleep hygiene education are recommended as first-line treatments in most clinical situations to treat insomnia disorder.
RESUMO
BACKGROUND: Although long-term use of benzodiazepines and z-drugs (BZDs) is not recommended, little is known about the stakeholders' perceptions. This study aimed to assess and compare the perceptions of BZD use and decision making regarding its discontinuation between psychiatric outpatients and psychiatrists. METHODS: A cross-sectional survey was conducted. RESULTS: Of 104 outpatients, 92% were taking hypnotics and 96% were taking anxiolytics for ≥a year, while 49% were willing to taper hypnotic/anxiolytics within a year of starting. Most psychiatrists felt that "patient and psychiatrist make the decision together on an equal basis" compared to patients (p < 0.001), while more patients felt that "the decision is (was) made considering the psychiatrists' opinion" compared to psychiatrists (p < 0.001). Of 543 psychiatrists, 79% reported "patients were not willing to discontinue hypnotic/anxiolytic" whereas a certain number of patients conveyed "psychiatrists did not explain in enough detail about hypnotic/anxiolytic discontinuation such as procedure (18.3%), timing (19.2%), and appropriate condition (14.4%)". CONCLUSION: The results suggest that the majority of psychiatric outpatients were taking hypnotic/anxiolytics for a long time against their will. There might be a difference in perceptions toward hypnotic/anxiolytic use and decision making for its discontinuation between psychiatric outpatients and psychiatrists. Further research is necessary to fill this gap.

Introduction: Benzodiazepines and non-benzodiazepines are still widely prescribed despite safety concerns and the introduction of novel hypnotics (orexin receptor antagonists [ORA] and melatonin receptor agonists [MRA]), which may be influenced by physicians' attitudes toward hypnotics. Methods: A questionnaire survey was administered to 962 physicians between October 2021 and February 2022, investigating frequently prescribed hypnotics and the reasons for their selection. Results: ORA were the most frequently prescribed at 84.3%, followed by non-benzodiazepines (75.4%), MRA (57.1%), and benzodiazepines (54.3%). Compared to non-frequent prescribers of hypnotics, a logistic regression analysis showed that frequent ORA prescribers were more concerned with efficacy (odds ratio [OR]: 1.60, 95% confidence interval [CI]: 1.01-2.54, p = 0.044) and safety (OR: 4.52, 95% CI: 2.99-6.84, p < 0.001), frequent MRA prescribers were more concerned with safety (OR: 2.48, 95% CI: 1.77-3.46, p < 0.001), frequent non-benzodiazepine prescribers were more concerned with efficacy (OR: 4.19, 95% CI: 2.91-6.04, p < 0.001), and frequent benzodiazepine prescribers were more concerned with efficacy (OR: 4.19, 95% CI: 2.91-6.04, p < 0.001) but less concerned with safety (OR: 0.25, 95% CI: 0.16-0.39, p < 0.001). Discussion: This study suggested that physicians believed ORA to be an effective and safe hypnotic and were compelled to prescribe benzodiazepine and non-benzodiazepine frequently, choosing efficacy over safety.
