RESUMO
BACKGROUND: New sleep-inducing drugs (eg, ramelteon, suvorexant, and lemborexant) have been shown to prevent delirium in high-risk groups. However, no single study has simultaneously evaluated the delirium-preventing effects of all novel sleep-inducing drugs in hospitalized patients. Therefore, this study aimed to clarify the relationship between sleep-inducing drugs and delirium prevention in patients hospitalized in general medical-surgical settings for nonpsychiatric conditions who underwent liaison interventions for insomnia. METHODS: This retrospective cohort study included patients treated in general medical-surgical settings for nonpsychiatric conditions with consultation-liaison psychiatry consult for insomnia. Delirium was diagnosed by fully certified psychiatrists using the Diagnostic and Statistical Manual of Mental Disorders 5 th edition. The following items were retrospectively examined from medical records as factors related to delirium development: type of sleep-inducing drugs, age, sex, and delirium risk factors. The risk factors of delirium development were calculated using adjusted odds ratios (aORs) via multivariate logistic regression analysis. RESULTS: Among the 710 patients analyzed, 257 (36.2%) developed delirium. Suvorexant (aOR, 0.61; 95% confidence interval [CI], 0.40-0.94; P = 0.02) and lemborexant (aOR, 0.23; 95% CI, 0.14-0.39; P < 0.0001) significantly reduced the risk of developing delirium. Benzodiazepines (aOR, 1.90; 95% CI, 1.15-3.13; P = 0.01) significantly increased this risk. Ramelteon (aOR, 1.30; 95% CI, 0.84-2.01; P = 0.24) and Z-drugs (aOR, 1.27; 95% CI, 0.81-1.98; P = 0.30) were not significantly associated with delirium development. CONCLUSIONS: The use of suvorexant and lemborexant may prevent delirium in patients with a wide range of medical conditions.

PURPOSE: To investigate the effects of an original education program on patients with epilepsy (PWE). The effects on knowledge about epilepsy, attitude to epilepsy, depression scales, and quality of life were investigated. METHOD: Thirty-five PWE participated in a lecture-style educational program using an original knowledge-oriented textbook. All patients were administered a total of four rating scales: the Knowledge about Epilepsy Scale (KES), the Attitude toward Epilepsy Scale (AES), and the Japanese version of the Quality of Life in Epilepsy Inventory (QOLIE-31-P), the Beck Depression Inventory (BDI). The KES and AES of patients (pKES and pAES) were compared to those of medical students (St) and residents (Rd). RESULTS: After education, pKES improved and showed significant differences among pre-and post-education and six months later. Before education, pKES was inferior to St and Rd. However, after education, pKES changed and became superior to St and Rd. Six months later, the advantage was lost, but not significantly. PAES also improved after education, with significant differences before, after, and six months later after education. PAES was statistically inferior to St and Rd before education, but the difference disappeared after education, and the effect persisted after six months. The non-depressed (BDI < 20) and depressed groups (BDI ⧠20) improved in the KES after education. About the AES, the non-depressive group has a statistical tendency, but not the depressive group. At six months, the depressed group's AES is significantly lower than the non-depressed group. CONCLUSION: While correct knowledge about epilepsy can improve attitudes and perceptions of epilepsy in PWE, special measures are needed for PWE with depression.

AIM: Rapid eye movement sleep behaviour disorder (RBD) is characterized by abnormal behaviours accordant with nightmares during rapid eye movement sleep and is considered a prodromal marker of dementia with Lewy body. Most common in the elderly population, RBD is generally treated with clonazepam (CZP), a long-term acting benzodiazepine antiepileptic. As such, alternative drugs for RBD are urgently needed to minimize the adverse effects peculiar to benzodiazepines. The efficacy of yokukansan (YKS), a traditional Japanese herbal medicine, on RBD was initially reported by Shinno et al. in 2008. However, no study has compared YKS with CZP. Therefore, this study aimed to clarify the possibility of using YKS as an alternative to CZP. METHODS: This was a retrospective cohort study conducted at Jikei University Affiliated Hospital. The subjects were selected from 36 outpatients who had been diagnosed with RBD based on the International Classification of Sleep Disorders, third edition. Of the 23 who met the inclusion criteria but not the exclusion criteria, 11 were treated with YKS monotherapy, and 12 were treated with CZP monotherapy. The primary outcome was the total score on the Japanese version of the Rapid Eye Movement Sleep Behaviour Disorder Questionnaire (RBDQ-JP), and the secondary outcomes were the scores from the eight-item Short-Form Health Survey and factors 1 and 2 of the RBDQ-JP. RESULTS: The mean total RBDQ-JP score significantly improved from 52.5 to 21.7 (P = 0.002) after treatment with YKS (mean dosage: 3.0 g/day), which was similar to the change after CZP treatment (from 43.8 to 21.3). On RBDQ-JP factor 1 (dream content), the mean score on five of six items significantly improved after treatment with YKS. There was no significant change in Short-Form Health Survey scores after treatment with either drug. Potassium concentrations were within the normal range in patients treated with YKS. CONCLUSIONS: The present results suggest that a small amount of YKS may be an alternative to CZP for RBD, without remarkable adverse events. Further study is needed to prospectively clarify the efficacy and safety of YKS in more detail.

The rate of those who have sleep problems increases due to aging. In Japan, a super-aging society, insomnia is a common disease. It is reported that the ratio of insomniacs over sixty year-old is 29.5 %. The sleep disturbance in the elderly is caused by multi factors, such as physiological, physical, psychosociological, psychiatric, and pharmacological factors. According to the latest diagnostic criteria of sleep disorders, ICSD-3, the concept of primary or secondary insomnia was abolished. Instead of that, insomnia is categorized by the duration of disease, and general doctors can diagnose sleep disorders more easily than the past. However, it is not necessary to consider the pathophysiological mechanism, there is a concern that the clinical level of insomnia treatment might decline in quality.

AIM: In autism spectrum disorder (ASD), abnormal sensory processing patterns are observed in various sensory modalities, including visual, auditory, touch, olfactory, taste, vestibular, and proprioceptive senses. Few studies have examined the relationship between sensory processing patterns and emotions, or their effects on daily life. We investigated the relationship between sensory processing patterns and emotional/behavioral problems in children with ASD. PARTICIPANTS AND METHODS: A retrospective chart review was conducted. Forty-three children with ASD (33 boys, 10 girls, median age 9 years) in the outpatient clinic of a psychiatric hospital participated; their parent (s) were invited to complete the Sensory Profile 2 (SP2) and the Child Behavior Checklist (CBCL) questionnaires. The participants' teachers were invited to complete the Teacher's Report Form (TRF). RESULTS: In the correlation analyses, each of the four quadrants of the SP2 (low registration, sensory seeking, hypersensitivity, and sensory avoiding) had significant positive correlations with different types of emotional and behavioral problems measured by the CBCL. Focusing on emotion, 'anxious/depressed' was correlated with low registration (r = 0.41) and sensory avoiding (r = 0.60), while 'withdrawal/depressed' was correlated with sensory avoiding (r = 0.46). Only one significant correlation was revealed between the SP2 and the TRF. CONCLUSION: Our results suggest a link between sensory processing patterns and emotional/behavioral problems. In school settings, the relationship between sensory processing patterns and emotional/behavioral problems may be easily overlooked.

BACKGROUND: Patients with major depressive disorder (MDD) and comorbid insomnia are often co-prescribed benzodiazepines (BZDs) or Z-drugs as hypnotics with antidepressants to manage persistent insomnia. However, factors associated with their long-term use remain unclear among MDD patients. METHODS: We retrospectively analyzed data from 351 MDD patients who started antidepressants with co-prescribed hypnotics (BZDs/Z-drugs) and investigated the prevalence of and factors associated with their long-term use at 12 months. We conducted logistic regression analyses of their long-term use, and compared insomnia severities between the continued and discontinued groups of hypnotics in 32 patients whose insomnia severities had been longitudinally assessed. RESULTS: 66.1% of patients had continued hypnotics for 12 months. Multiple logistic regression analysis revealed that the diazepam-equivalent dose of hypnotics at the start of the combined treatment (>5 mg), the presence of chronic insomnia prior to MDD, and hospitalization correlated with their long-term use (all p < 0.01). We also found the relationship between the insufficient amelioration of insomnia severities and their long-term use. However, confidence in these results is tempered by various factors, including the dependence on hypnotics, the patient's attitude about hypnotic treatment, and the exclusion of subjects treated with other drugs such as sedative antidepressants or antipsychotics. CONCLUSIONS: These clinical indicators may facilitate the selection of treatment strategies for MDD with comorbid insomnia. To avoid the long-term use of hypnotics, their dose at the start of the combined treatment needs to be adequate (≤5 mg) and alternative treatments to BZDs/Z-drugs are required for refractory insomnia.
RESUMO
BACKGROUND: Although the therapeutic relationship (or 'alliance') is well known to be a key component of psychiatric treatment, there has been no simple way to objectively measure the patient-therapist relationship. Here, we measured the psychological distance between patients and their therapists by using the Pictorial Representation of Illness and Self Measure (PRISM). PATIENTS AND METHODS: We analyzed the patient-therapist relationship of 112 patients from two hospitals in Japan (54 males, 57 females, 1 unknown; age 46.20 ± 15.03 years [mean ± SD]) who completed the PRISM and self report questionnaires (LSNS-6, K6, and BASIS-32) about their social network, psychological distress, and outcomes of mental health treatment. RESULTS: PRISM measurements were available for all patients who consented to participate. In the comparison by disease category, schizophrenia recorded the closest distance to the psychiatrist in charge, followed by bipolar disorder, depression, and neurotic disorder. Regarding the distance to the psychiatrist in charge, PRISM showed a weak negative correlation (r = -0.23, p < 0.05) with age, indicating that with increasing age, the therapeutic rela tionship was more important to the patients. CONCLUSION: Our findings indicate the possibility of implementing PRISM to assess the impact of the therapeutic relationship in patients with a wide range of psychiatric disorders, and they suggest that PRISM holds great potential for clinical application.

OBJECTIVE/BACKGROUND: The short-term efficacy and safety of daridorexant, a dual orexin receptor antagonist, has been demonstrated in Japanese patients with insomnia disorder. The objective of this study was to evaluate, in a non-overlapping patient population to the short-term study, the long-term safety and efficacy of daridorexant in Japanese patients with insomnia disorder. PATIENTS/METHODS: In this Phase 3 open-label study conducted in Japan, 154 patients with insomnia disorder were randomized to daridorexant 50 mg (n = 102) or 25 mg (n = 52) for 52 weeks. The primary objective was to assess the safety and tolerability of daridorexant for up to 1 year. Secondary exploratory objectives were to evaluate the long-term efficacy of daridorexant on subjective sleep parameters (total sleep time, latency to sleep onset and wake after sleep onset) and daytime functioning (Insomnia Daytime Symptoms and Impacts Questionnaire). RESULTS: The incidence of treatment-emergent adverse events (TEAEs) was 74 % and 58 % in the 50 mg and 25 mg groups respectively. No serious drug-related TEAEs were reported. Both doses improved next-morning sleepiness (Visual Analog Scale) throughout the study. Five adjudicated adverse events of special interest were reported; excessive daytime sleepiness (n = 1, 25 mg; n = 2, 50 mg), sleep paralysis (n = 1, 50 mg) and nightmare (n = 1, 25 mg). Improvements in sleep and daytime functioning were maintained from Week 2 (first assessment) through to Week 52 in both dose groups. CONCLUSIONS: Up to 52-weeks, daridorexant was well tolerated with sustained improvement in sleep onset, sleep maintenance and daytime functioning, supporting its long-term use in Japanese patients with insomnia disorder.
RESUMO
AIMS: In Japan, the daily dosage of hypnotic drugs for insomnia treatment is increasing year by year, and over-dependence on treatment with hypnotic drugs is a major problem. This study aimed to examine the factors related to the elimination of prescriptions of three or more hypnotic drugs within 1 year in our clinic. METHODS: We conducted two surveys. Survey â assessed the frequency of prescriptions of three or more hypnotic drugs by retrospectively reviewing the medical records of all patients who visited general and psychiatric outpatient clinics from January 2013 to March 2019. Survey â¡ assessed changes in prescriptions of hypnotic and psychotropic drugs within the subsequent year by retrospectively reviewing the medical records of all patients prescribed three or more hypnotic drugs who visited neuropsychiatric outpatient clinics multiple times between April 2013 and March 2019. RESULTS: The frequency of prescribing three or more hypnotic drugs was six to nine times higher in psychiatry than in other departments. Flunitrazepam and brotizolam were the most common drugs prescribed and had the second lowest discontinuation rate after zolpidem. Conversely, eszopiclone, zopiclone, and suvorexant had the highest discontinuation rates. The success factors for drug reduction were age (odds ratio [OR]: 0.97, p < 0.0037), trazodone addition (OR: 12.86, p < 0.0194) and number of years of psychiatric experience. CONCLUSIONS: The characteristics and success factors in relation to drug reduction in patients with multiple prescriptions of hypnotic drugs identified in this study may contribute to solving the problem of multiple prescriptions of hypnotic drugs.

INTRODUCTION: For patients with chronic insomnia, conventional therapy may not always provide satisfactory efficacy and safety. Thus, switching to an alternative therapeutic agent can be explored. However, there is a lack of prospective studies evaluating the effectiveness of such changes. This prospective, non-randomized, open-label, interventional, multicenter study assessed whether Japanese patients with chronic insomnia dissatisfied with treatment could transition directly to lemborexant (LEM) from four cohorts-non-benzodiazepine sedative-hypnotic (zolpidem, zopiclone, or eszopiclone) monotherapy, dual orexin receptor antagonist (suvorexant) monotherapy, suvorexant + benzodiazepine receptor agonists (BZRAs), and melatonin receptor agonist (ramelteon) combination. We evaluated whether transitioning to LEM improved patient satisfaction based on efficacy and safety. METHODS: The primary endpoint was the proportion of successful transitions to LEM at 2 weeks (titration phase end), defined as the proportion of patients on LEM by the end of the 2-week titration phase who were willing to continue on LEM during the maintenance phase (Weeks 2-14). Patient satisfaction and safety (the incidence of treatment-emergent adverse events [TEAEs]) were assessed at 14 weeks (end of titration and maintenance phases). RESULTS: Among the 90 patients enrolled, 95.6% (95% confidence interval: 89.0-98.8%) successfully transitioned to LEM at 2 weeks. The proportions of patients who successfully continued on LEM were 97.8% and 82.2% at the end of the titration and maintenance phases (Weeks 2 and 14), respectively. The overall incidence of TEAEs was 47.8%; no serious TEAEs occurred. In all cohorts, the proportions of patients with positive responses were higher than the proportions with negative responses on the three scales of the Patient Global Impression-Insomnia version. During the maintenance phase, Insomnia Severity Index scores generally improved at Weeks 2, 6, and 14 of LEM transition. CONCLUSIONS: Direct transition to LEM may be a valid treatment option for patients with insomnia who are dissatisfied with current treatment. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT04742699.

Psychotic symptoms often occur as a complication in Parkinson's disease patients, and a set of criteria for Parkinson's disease with psychosis (PDPsy) has been established. Among these criteria, hallucinations are one of the specific symptoms, with visual hallucinations being the most common. While atypical antipsychotic agents are often used for the treatment of PDPsy, adverse effects, including extrapyramidal symptoms, often hinder its continuation or tolerance. There have been some reports and reviews indicating that antidepressants may be effective for PDPsy and other forms of dementia with psychosis. In this report, we present a patient with PDPsy who was treated with one of the new-generation antidepressants, mirtazapine. Mirtazapine improved the patient's refractory psychotic symptoms, especially her visual hallucinations, without worsening her motor symptoms.

Insomnia is one of the most frequently encountered diseases in clinical practice, and about half of the patients have a long-term course. Therefore, proactive prevention against chronicity is required, using a non-pharmacological approach for insomnia (sleep hygiene). Pharmacological treatment, needs to decrease the risk of appearance of rebound insomnia, the risk of the patient falling, drug dependence, and cognitive dysfunctions caused by hypnotics. In view of this, it is recommended to use novel sleep medications such as orexin receptor antagonists and melatonin receptor agonists.

STUDY OBJECTIVES: This study assessed the effects and safety of the smartphone-based cognitive behavioral therapy for insomnia (CBT-I) app compared with the sham app. METHODS: In this multicenter, double-blind, and parallel-group study, 175 patients with insomnia were randomized to a smartphone-based CBT-I app (Active, n = 87) or a sham app (Sham, n = 88) group. The primary endpoint was the change in Athens Insomnia Score (AIS) from baseline after 8 weeks of treatment. RESULTS: The change in AIS (mean ± standard deviation) from baseline, assessed using a modified-intent-to-treat analysis, was -6.7 ± 4.4 in the Active group and -3.3 ± 4.0 in the Sham group. The difference in the mean change between the groups was -3.4 (p < .001), indicating a greater change in the Active group. The change in CGI-I from the baseline was 1.3 ± 0.8 in the Active group and 0.7 ± 0.8 in the Sham group (p < .001). The proportion of patients with an AIS less than 6 was 37.9% in the Active group and 10.2% in the Sham group (p < .001). As for the safety assessment, no adverse reactions or device failures were detected in the Active group. CONCLUSIONS: This study demonstrated the effectiveness of a smartphone-based CBT-I system for treating insomnia.

Recently, addiction to regular doses of hypnotics has become a problem. While many patients report a desire to reduce their dosage, many do not agree with their physicians' suggestions for reduction. In this study, we created an online short video targeting patient motivation to reduce hypnotics usage and examined its efficacy and factors associated with the intention to reduce medication. We created a 10 min video that included "sleep education," "guidance for reducing the use of hypnotics," and "systematic motivation for reducing the use of hypnotics" and posted it on our website. For 1 year, we conducted a questionnaire survey to determine the effectiveness of the video and factors associated with the intention to reduce hypnotics use. Of 4548 viewers, 609 (13.4%) completed the questionnaire, 369 (67.9%) of whom used hypnotics. Most respondents were older adults. The intention to reduce medication use was significantly strengthened after watching the video in 37.7% of medication users (effect size 0.404). In the group that was not inclined toward medication reduction before viewing, 85.2% of patients had stronger intentions to reduce medication use after watching the video (effect size 0.818). "Memorable content about side effects" was extracted as a factor related to reinforcement of the intention to reduce medication use, suggesting that prescribing physicians' descriptions of current insomnia treatment is inadequate in explaining side effects to patients. A short informational video can have beneficial effects on patients' motivation for dose reduction or cessation of hypnotics.

RESUMO
OBJECTIVE: Polysomnographic findings in neurodevelopmental disorders have been reported, but previous studies have had several limitations. The purpose of this study was to characterize sleep structure in untreated adults diagnosed with ADHD, excluding ADHD-related sleep disorders as determined by polysomnography and multiple sleep latency testing. METHODS: This study included 55 patients aged 18 years or older who visited the Kurume University Hospital Sleep Clinic between April 2015 and March 2020. The diagnosis of ADHD was determined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (ADHD group, n = 28; non-ADHD, n = 27). RESULTS: The ADHD group had significantly longer slow wave sleep (SWS) duration than the non-ADHD group (ADHD: 68.3 ± 31.0 minutes vs. non-ADHD: 43.4 ± 36.6 minutes; p = .0127). CONCLUSIONS: The increased SWS volume observed in drug-naïve adult patients with ADHD may be related to the pathogenesis of this disorder.

Physical symptoms such as fatigue and muscle weakness, and psychiatric symptoms like depression and anxiety are considered as complications and sequelae of COVID-19. This epidemiological study investigated the actual status of psychiatric symptoms and disorders caused by COVID-19, from four major university hospitals and five general hospitals in Fukuoka Prefecture, Japan, having a population of 5 million. We conducted a survey of psychiatric disorders associated with COVID-19 using Diagnosis Procedure Combination (DPC) data and the psychiatric records of the hospitals. In the study period from January 2019 to September 2021, 2743 COVID-19 admissions were determined from DPC data across the nine sites. These subjects had significantly more anxiety, depression, and insomnia, and were receiving higher rates of various psychotropic medications than controls influenza and respiratory infections. A review of psychiatric records revealed that the frequency of organic mental illness with insomnia and confusion was proportional to the severity of COVID-19 infection and that anxiety symptoms appeared independent of infection severity. These results indicate that COVID-19 is more likely to produce psychiatric symptoms such as anxiety and insomnia than conventional infections.
RESUMO
The average of sleep time in Japanese is decreasing year by year. According to data of NHK's survey, it has been lowered by one hour since 1960. The reasons are different between generations. In adolescence, the increased frequency of using internet and convenience store may cause the shortage of sleep and the deterioration of circadian rhythms. In adulthood, the working environment, such as increased number of shift-workers and excessive job time, is getting worse, and it could shorten the sleep time and exacerbate sleep quality. In old age, the frequency of taking medicine becomes higher in connection with aging. We need to be careful about the interactions between hypnotics and taking drugs prescribed to treat complications.

PURPOSE: Preventing falls in patients is one of the most important concerns in acute hospitals. Balance disorder and hypnotic drugs lead to falls. The Standing Test for Imbalance and Disequilibrium (SIDE) is developed for the evaluation of static standing balance ability. There have been no reports of a comprehensive assessment of falls risk including hypnotic drugs and SIDE. The purpose of this study was to investigate the fall rate of each patient who took the hypnotic drug and the factor associated with falls. METHODS: Fall rates for each hypnotic drug were calculated as follows (number of patients who fell/number of patients prescribed hypnotic drug x 100). We investigated the hypnotic drugs as follows; benzodiazepine drugs, Z-drugs, melatonin receptor agonists, and orexin receptor antagonists. Hypnotic drug fall rate was analyzed using Pearson's chi-square test. Decision tree analysis is the method we used to discover the most influential factors associated with falls. RESULTS: This study included 2840 patients taking hypnotic drugs. Accidents involving falls were reported for 211 of inpatients taking hypnotic drugs. Z-drug recipients had the lowest fall rate among the hypnotic drugs. We analyzed to identify independent factors for falls, a decision tree algorithm was created using two divergence variables. The SIDE levels indicating balance disorder were the initial divergence variable. The rate of falls in patients at SIDE level ⦠2a was 14.7%. On the other hand, the rate of falls in patients at SIDE level ⧠2b was 2.9%. Gender was the variable for the second classification. In this analysis, drugs weren't identified as divergence variables for falls. CONCLUSION: The SIDE balance assessment was the initial divergence variable by decision tree analysis. In order to prevent falls, it seems important not only to select appropriate hypnotic drugs but also to assess patients for balance and implement preventive measures.

Idiopathic hypersomnia (IH) is a rare sleep disorder characterized by excessive daytime sleepiness, great difficulty upon awakening, and prolonged sleep time. In contrast to narcolepsy type 1, which is a well-recognized hypersomnia, the etiology of IH remains poorly understood. No susceptibility loci for IH have been identified, although familial aggregations have been observed among patients with IH. Narcolepsy type 1 is strongly associated with human leukocyte antigen (HLA)-DQB1*06:02; however, no significant associations between IH and HLA alleles have been reported. To identify genetic variants that affect susceptibility to IH, we performed a genome-wide association study (GWAS) and two replication studies involving a total of 414 Japanese patients with IH and 6587 healthy Japanese individuals. A meta-analysis of the three studies found no single-nucleotide polymorphisms (SNPs) that reached the genome-wide significance level. However, we identified several candidate SNPs for IH. For instance, a common genetic variant (rs2250870) within an intron of PDE9A was suggestively associated with IH. rs2250870 was significantly associated with expression levels of PDE9A in not only whole blood but also brain tissues. The leading SNP in the PDE9A region was the same in associations with both IH and PDE9A expression. PDE9A is a potential target in the treatment of several brain diseases, such as depression, schizophrenia, and Alzheimer's disease. It will be necessary to examine whether PDE9A inhibitors that have demonstrated effects on neurophysiologic and cognitive function can contribute to the development of new treatments for IH, as higher expression levels of PDE9A were observed with regard to the risk allele of rs2250870. The present study constitutes the first GWAS of genetic variants associated with IH. A larger replication study will be required to confirm these associations. Supplementary Information: The online version contains supplementary material available at 10.1007/s41105-021-00349-2.
RESUMO
AIMS: Benzodiazepine receptor agonists (BZ-RAs) are frequently prescribed to treat insomnia; however, their long-term use is not recommended. To introduce an appropriate pharmaco-therapy, the current state and background factors of BZ-RAs' dependence must be elucidated. In this study, we developed a Japanese version of the Benzodiazepine Dependence Self-Report Questionnaire (Bendep-SRQ-J) and conducted a study of BZ-RAs' use disorder. METHODS: The Bendep-SRQ-J was created with permission from the original developer. Subjects were inpatients and outpatients receiving BZ-RAs between 2012 and 2013. Clinical data collected were Bendep-SRQ-J scores, sleep disorders for which BZ-RAs were prescribed, physical comorbidities, psychotropic drugs, and lifestyle factors. Logistic analysis was performed to extract factors associated with severe symptoms. RESULTS: Of the 707 patients prescribed BZ-RAs, 324 had voluntarily tapered or discontinued their drugs. Logistic analysis showed that the total number of drugs administered in the last 6 months correlated with both worsening of symptoms or conditions. This was more notable among younger patients, and the proportion of patients with severe symptoms or conditions increased with the increasing number of drugs. CONCLUSION: Using the Bendep-SRQ-J, we elucidated the current state of BZ-RA dependence. Nearly half of the patients were non-compliant. The proportion of patients with severe symptoms or disease conditions increased with the increase in the number of drugs administered. These findings highlight the need for clinicians to be aware of the likelihood of benzodiazepine dependence, especially in young patients and patients prescribed multiple hypnotics.
