    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.

     View Summary

    AIM: This study aimed to examine the effect of Japanese policies for appropriate hypnotics use and novel hypnotics (e.g., melatonin receptor agonist [MRA] and orexin receptor antagonist [ORA]) on long-term prescriptions of hypnotics. METHODS: This retrospective study was conducted using a large-scale health insurance claims database. Among subscribers prescribed hypnotics at least once between April 2005 and March 2021, those prescribed hypnotics for the first time after being included in the database in three periods (period 1, April 2012-March 2013; period 2, April 2016-March 2017; and period 3, April 2018-March 2019) were eligible. These were set considering the timing of the 2014 and 2018 medical fee revisions (2014 for polypharmacy of three or more hypnotics, 2018 for long-term prescription of benzodiazepine receptor agonists for >12 months). The duration of consecutive prescriptions of hypnotics over 12 months was evaluated. Factors associated with short-term prescriptions of hypnotics were also investigated. RESULTS: In total, 186,535 participants were newly prescribed hypnotics. The mean duration of prescriptions was 2.9 months, and 9.3% of participants were prescribed hypnotics for 12 months. Prescription periods were not associated with short-term prescriptions of hypnotics. ORA use was associated with short-term prescriptions of hypnotics (adjusted hazard ratio, 1.077; 95% confidence interval, 1.035-1.120; p<0.001), but MRA use was not. CONCLUSION: Japanese policies had no statistically significant effect on long-term prescriptions of hypnotics. Although this study suggests initiating ORA for insomniacs as a candidate strategy to prevent long-term prescriptions of hypnotics, further research is necessary to draw conclusions.

     View Summary

    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 &lt; 0.001), while more patients felt that “the decision is (was) made considering the psychiatrists’ opinion” compared to psychiatrists (p &lt; 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.
