Abstract
Importance Dose-related effects of antipsychotic medications may increase mortality in children and young adults. Objective To compare mortality for patients aged 5 to 24 years beginning treatment with antipsychotic vs control psychiatric medications. Design, Setting, and Participants This was a US national retrospective cohort study of Medicaid patients with no severe somatic illness or schizophrenia or related psychoses who initiated study medication treatment. Study data were analyzed from November 2022 to September 2023. Exposures Current use of second-generation antipsychotic agents in daily doses of less than or equal to 100-mg chlorpromazine equivalents or greater than 100-mg chlorpromazine equivalents vs that for control medications (α agonists, atomoxetine, antidepressants, and mood stabilizers). Main Outcome and Measures Total mortality, classified by underlying cause of death. Rate differences (RDs) and hazard ratios (HRs) adjusted for potential confounders with propensity score-based overlap weights. Results The 2 067 507 patients (mean [SD] age, 13.1 [5.3] years; 1 060 194 male [51.3%]) beginning study medication treatment filled 21 749 825 prescriptions during follow-up with 5 415 054 for antipsychotic doses of 100 mg or less, 2 813 796 for doses greater than 100 mg, and 13 520 975 for control medications. Mortality was not associated with antipsychotic doses of 100 mg or less (RD, 3.3; 95% CI, -5.1 to 11.7 per 100 000 person-years; HR, 1.08; 95% CI, 0.89-1.32) but was associated with doses greater than 100 mg (RD, 22.4; 95% CI, 6.6-38.2; HR, 1.37; 95% CI, 1.11-1.70). For higher doses, antipsychotic treatment was significantly associated with overdose deaths (RD, 8.3; 95% CI, 0-16.6; HR, 1.57; 95% CI, 1.02-2.42) and other unintentional injury deaths (RD, 12.3; 95% CI, 2.4-22.2; HR, 1.57; 95% CI, 1.12-2.22) but was not associated with nonoverdose suicide deaths or cardiovascular/metabolic deaths. Mortality for children aged 5 to 17 years was not significantly associated with either antipsychotic dose, whereas young adults aged 18 to 24 years had increased risk for doses greater than 100 mg (RD, 127.5; 95% CI, 44.8-210.2; HR, 1.68; 95% CI, 1.23-2.29). Conclusions and Relevance In this cohort study of more than 2 million children and young adults without severe somatic disease or diagnosed psychosis, antipsychotic treatment in doses of 100 mg or less of chlorpromazine equivalents or in children aged 5 to 17 years was not associated with increased risk of death. For doses greater than 100 mg, young adults aged 18 to 24 years had significantly increased risk of death, with 127.5 additional deaths per 100 000 person-years.

Abstract
Objective: The aim of the study was to assess monitoring of adverse drug reaction (ADR)-related parameters in children, youth, and young adults treated with second-generation antipsychotic drugs (SGAs) prescribed by general practitioners (GPs). Methods: This retrospective follow-up study included children, youth, and young adults aged 0 - 24 years, who had an initial prescription of an SGA recorded in the Clinical Practice Research Datalink between 2000 and 2017, and who were prescribed an SGA more than once for a duration of at least 6 months. It included an assessment of which ADR-related physical parameters (weight, height, body-mass index, waist circumference, pulse, blood pressure, and heart examination) and laboratory parameters (glucose, HbA1c, lipids, and prolactin) were monitored in children, youth, and young adults at least once every 6-month period, stratified by sex, age categories, and calendar years. Results: In total, 7006 patients were included and the mean duration of follow-up was 1.6 years. Monitoring frequencies of all parameters were below 25%. Blood pressure and weight were monitored in 23.6% and 23.4%, respectively, of all children, youth, and young adults during the first half year; waist circumference was monitored in 0.2%. Females were monitored more often than males, some differences between age categories were observed, and monitoring frequencies increased after 2000, but did not exceed 35% in any year. Conclusion: Monitoring frequencies of ADR-related parameters in children, youth, and young adults treated with SGAs prescribed by a GP were low. Monitoring in primary care should be improved to enable a better evaluation of the benefit-risk balance during antipsychotic drug therapy.

Abstract
Background and objective A significant proportion of the adult population in the United States (US) live with some form of mental illness. The more prevalent conditions of depression and anxiety are typically managed in primary care settings rather than specialty care. The aim of this study was to determine the efficacy of a novel, measurement-driven psychiatric treatment platform delivered via an online telemental health platform as compared to treatment as usual (TAU). Methods The TAU dataset and the telemental health platform (Brightside) dataset were constructed based on the total populations of adult patients receiving care for depression from January 2018 through December 2020 (November 2018 through March 2021 for the Brightside group). Patients in both groups had a primary mental health diagnosis of depression and the presence of a positive screen for depression as measured by the Patient Health Questionnaire-9 (PHQ-9) upon initiation of treatment. HITLAB, an independent digital health verification and testing lab, conducted comparative analyses of the two groups using the Chi-square test of independence. Results Close to 80% of telemental health platform patients experienced a reduction of 5 or more points from their baseline PHQ-9 score as compared to 52% of TAU patients. The mean reduction in PHQ-9 score was slightly higher in the Brightside group (-11.5) versus the TAU group (-10.1). Chi-square tests of independence [x2 (1, n=6281) = 256.75, p≤0.001] for meaningful reduction and for remission [x2 (1, n=6281) = 105.50 p≤0.001] were highly significant. Conclusion The telemental health platform patients performed significantly better than those under psychiatric TAU in terms of reduction in symptoms of depression in adults.

Abstract
OBJECTIVE Second-generation antipsychotic (SGA) prescription use has become increasingly prevalent in the pediatric population, despite metabolic adverse effects. A significant number of SGA medications are prescribed for indications that are not approved by the FDA. This study aimed to quantify clinician adherence to the FDA and professional society indication, age, and dosing guidelines when prescribing SGA medications for pediatric patients. METHODS We used electronic health record data from 3 health care systems. We analyzed outpatient encounters where a pediatric patient was prescribed an SGA during an 18-month time frame. Clinician prescribing patterns were compared to a therapeutic regimen table created using professional society guidelines and FDA medication labels. RESULTS Most of the encounters listed an indication that was not documented as a recommended use (84.3%). Most prescriptions aligned with the generalized dose guidelines (93.8%) and age guidelines (94.9%). Clinicians were more likely to follow indication guidelines when prescribing risperidone, the highest adherence medication, compared with quetiapine, the lowest adherence medication (odds ratio [OR], 2.5; 95% CI, 1.1-6.0). Compared with prescriptions for younger children, clinicians were more likely to follow indication guidelines for children aged 13 to 15 years (OR, 2.8; 95% CI, 1.1-7.2) and 16 to 18 years (OR, 3.1; 95% CI, 1.2-8.1). CONCLUSION Community clinicians overall demonstrated a low level of adherence to indication guidelines when prescribing SGA medications to pediatric populations, while maintaining higher adherence to age and dosing guidelines. Older children were more likely to receive an SGA prescription for recommended indications compared with younger children.

Abstract
Objectives: The aim of this study is to evaluate the antipsychotics prescribed by child psychiatrists and their applications on the follow-up of these drugs. Methods: The universe of this research included consultant physicians and child psychiatry residents working in the field. A questionnaire has been created that assesses the use of antipsychotics and follow-up processes of physicians. The survey involved 19 questions. Contents of the survey were sociodemographic data, short-term and long-term follow-up of antipsychotic drugs, side-effect intervention strategies, and diagnoses of the most commonly preferred antipsychotic medications. The survey was delivered via e-mail and sent as a message to the child and adolescent psychiatrists in Turkey. Results: One hundred sixty-one physicians working in the field of child and adolescent psychiatry participated in the study. Aripiprazole (32.2%), risperidone (30.4%), and quetiapine (14.9%) were three most commonly prescribed antipsychotics. Disruptive behavior-related disorders (28.9%), behavior problems related to autism spectrum disorder (20.7%), behavior problems related to intellectual disability (14.5%), and attention-deficit/hyperactivity disorder (12.4%) were the most common diagnoses requiring antipsychotics medications. Before starting antipsychotic treatment, the most commonly evaluated parameters were body mass index (BMI) (47.2%), waist circumference (10.5%), blood pressure (28.5%), lipid profile (37%), and blood glucose level (41.6%). When the evaluations made at least in a year after starting antipsychotic drug therapy were examined, 80.2% of physicians reported blood glucose, 79.6% lipid profile, 65.7% BMI, 59.1% blood pressure, and 26.6% waist circumference measurement almost always done. Conclusions: The results showed that the adherence to recommendations in guidelines for the screening of antipsychotic-related side effects was low. This study suggests that interventions should be made about antipsychotic monitoring training to physicians.

Abstract
AIM Psychotropic prescribing by paediatricians is increasingly common, and there is considerable variation in care provided. The aims of this study were to examine current rates of psychotropic prescribing in the developmental-behavioural outpatient clinics at the Royal Children's Hospital's Centre for Community Child Health, and to compare rates between paediatric consultants and advanced trainees. METHODS Data were extracted for appointment encounters from electronic medical records across 12 months in 2017. Patient demographics, provider and medication order data were analysed using Excel and STATA to calculate logistic regression, standard deviation, percentages and means. RESULTS From 5069 encounters, there were 847 (16.7%) that included psychotropic prescribing. Advanced trainees prescribed psychotropic medications in only 4.4% of their encounters compared with consultants who prescribed these medications in 23% of encounters (P < 0.001). Stimulants were the most commonly prescribed psychotropic medication (62%), either alone (86.3%) or in combination (13.7%). CONCLUSIONS Psychotropic prescribing rates were lower than expected. Advanced trainees may need more experience in psychotropic prescribing.

Abstract
Tardive dyskinesia (TD) encompasses the spectrum of iatrogenic hyperkinetic movement disorders following exposure to dopamine receptor-blocking agents (DRBAs). Despite the advent of atypical or second- and third-generation antipsychotics with a presumably lower risk of complications, TD remains a persistent and challenging problem. Prevention is the first step in mitigating the risk of TD, but early recognition, gradual withdrawal of offending medications, and appropriate treatment are also critical. As TD is often a persistent and troublesome disorder, specific antidyskinetic therapies are often needed for symptomatic relief. The vesicular monoamine transporter 2 (VMAT2) inhibitors, which include tetrabenazine, deutetrabenazine, and valbenazine, are considered the treatment of choice for most patients with TD. Deutetrabenazine-a deuterated version of tetrabenazine-and valbenazine, the purified parent product of one of the main tetrabenazine metabolites, are novel VMAT2 inhibitors and the only drugs to receive approval from the US FDA for the treatment of TD. VMAT2 inhibitors deplete presynaptic dopamine and reduce involuntary movements in many hyperkinetic movement disorders, particularly TD, Huntington disease, and Tourette syndrome. The active metabolites of the VMAT2 inhibitors have high affinity for VMAT2 and minimal off-target binding. Compared with tetrabenazine, deutetrabenazine and valbenazine have pharmacokinetic advantages that translate into less frequent dosing and better tolerability. However, no head-to-head studies have compared the various VMAT2 inhibitors. One of the major advantages of VMAT2 inhibitors over DRBAs, which are still being used by some clinicians in the treatment of some hyperkinetic disorders, including TD, is that they are not associated with the development of TD. We also briefly discuss other treatment options for TD, including amantadine, clonazepam, Gingko biloba, zolpidem, botulinum toxin, and deep brain stimulation. Treatment of TD and other drug-induced movement disorders must be individualized and based on the severity, phenomenology, potential side effects, and other factors discussed in this review.

Abstract
INTRODUCTION Two risk minimization (RM) tools-a healthcare professional frequently asked questions (HCP-FAQs) brochure and a patient/caregiver information brochure (PCIB)-were developed for HCPs and for adolescents (aged ≥ 13 years) receiving aripiprazole for bipolar I mania and their caregivers. OBJECTIVES This study evaluated the effectiveness of these RM tools in improving the awareness and education of HCPs and patients/caregivers. METHOD The RM tools were distributed to HCPs (identified in agreement with the marketing authorization holder [MAH] and local regulatory authorities), who in turn distributed the PCIBs to patients/caregivers. A web-based survey was then conducted targeting HCPs and patients/caregivers. RESULTS The response rate was low: 118 of 23,282 invited HCPs and 16 patients/caregivers completed the survey. Overall, 42% (49/118) of HCP respondents were aware of aripiprazole RM tools; of these, 59% (29/49) of HCPs read them at least once and 66% (19/29) of these used the RM tools while discussing the benefit-risk profile of aripiprazole with patients/caregivers. In total, 30 of the 118 HCPs (25%) were aware of the PCIB, and 26 distributed it to their patients/caregivers, whereas seven HCPs advised them to read the brochure. Overall, 15 of the 16 patients/caregivers were aware of the PCIB, and 13 read/referred to it. Of these, 12 found the PCIB useful, and five monitored their weight while receiving aripiprazole and reported potential risks immediately to their HCP. CONCLUSION The response rate to the survey was low, and the tools displayed limited utility and effectiveness in improving awareness and education in a small number of responders. Therefore, the aripiprazole risk management plan was amended, and the tools were discontinued.

Abstract
OBJECTIVES To describe a cohort of young users of risperidone and quetiapine in the province of Manitoba (Canada) and assess the risk for movement disorders in the two treatments. METHODS This was a population-based study conducted on all residents of the province of 19 years of age and younger who received prescriptions for risperidone or quetiapine between April 1, 1996, and March 31, 2011. Incident rates of antipsychotic use were reported. The risk for movement disorders in patients treated with quetiapine compared with those treated with risperidone was assessed by time-to-event analysis using Cox proportional hazards models. RESULTS Between April 1, 1996, and March 31, 2011, 23,888 youth (age ≤19 years) were prescribed an antipsychotic agent. Among them, 8756 were identified as new incident users. After applying exclusion criteria, 2594 individuals comprised the cohort of users of risperidone and quetiapine. The use of quetiapine was associated with a lower risk of extrapyramidal symptoms (EPSs) adverse events. The unadjusted and adjusted hazard ratios (95% confidence interval [CI]) for quetiapine versus risperidone were 0.83 (0.56-1.25) and 0.53 (0.34-0.83), respectively. CONCLUSION EPS diagnoses have been detected in children treated with quetiapine; however, the risk of movement disorders appears to be higher with treatment with risperidone. Clinicians should always take into consideration the risk-benefit before treating children with antipsychotic medications and should be vigilant of the onset of drug-induced adverse events.

de Kuijper GM, Hoekstra PJ. Physicians' reasons not to discontinue long-term used off-label antipsychotic drugs in people with intellectual disability. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2017; 61:899-908. [PMID: 28560761 DOI: 10.1111/jir.12385] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2016] [Revised: 03/30/2017] [Accepted: 04/26/2017] [Indexed: 06/07/2023]
Abstract
BACKGROUND People with intellectual disability (ID) frequently use antipsychotic drugs on an off-label base, often for many years. Physicians' decisions to discontinue these drugs not only depend on patient characteristics, like the presence of mental or behavioural disorders, but also on environmental factors, such as inappropriate living circumstances, and on attitudes, knowledge and beliefs of staff, clients and their representatives towards the effects of antipsychotic drug use. In this study, we therefore investigated the influence of participant and setting-related factors on decisions of physicians not to discontinue off-label prescribed antipsychotics. METHODS The study took place in living facilities of six service providers for people with ID spread over the Netherlands and staffed with support professionals, nurses, behavioural scientist and physicians and was part of an antipsychotics discontinuation trial. ID physicians had to decide whether the off-label use of antipsychotics could be discontinued. Medical and pharmaceutical records were used to establish the prevalence of antipsychotic drug use in the study population, along with duration of use and whether the use was off-label. Reasons of physicians not to discontinue the prescription of antipsychotics in those participants who used off-label antipsychotics for more than a year were collected and categorised as related to participant or setting characteristics, including lack of consent to discontinue, and staff members, participants or their legal representatives. RESULTS Of the 3299 clients of the service providers, 977 used one or more antipsychotic drugs. The prevalence of antipsychotic drug use was 30%. Reasons for use were in 5% of cases, a chronic psychotic disorder classified according to Diagnostic System Mental Disorders, Fourth Edition, criteria, in 25%, present or past (suspected) non-schizophrenia-related psychotic symptoms and in 69%, challenging behaviours. Overall, physicians were willing to discontinue their prescriptions in 51% of cases, varying from 22% to 87% per service provider. The odds for decisions of physicians to discontinue off-label prescriptions varied from 0.19 to 13.95 per service provider. The variables 'a living situation with care and support' and 'challenging behaviour' were associated with a higher chance of discontinuation. The main reasons for decisions not to discontinue were concerns for symptoms of restlessness, the presence of an autism spectrum disorder, previously unsuccessful attempts to discontinue and objections against discontinuation of legal representatives. Reasons for physicians' decisions not to discontinue the off-label use of antipsychotics varied largely between the service providers. CONCLUSIONS The prevalence of antipsychotic drug use for off-label indications in people with ID remains high. The results of this study indicate that there is a large variation in clinical practice of physicians regarding discontinuation of long-term antipsychotic drug prescriptions, which may be partially related to environmental factors as setting culture and attitudes of staff towards off-label antipsychotic drug use in persons with ID.

Abstract
INTRODUCTION Tardive dyskinesia (TD) is a hyperkinetic movement disorder that may result from treatment with antipsychotics or other dopamine receptor blocking agents. Underlying pathophysiology is incompletely understood but since the 1970s dopamine depleting agents have been used to reduce involuntary movements. The search for safe, effective treatments for TD is ongoing. Valbenazine, a novel VMAT2 inhibitor, has recently been FDA approved for treatment of TD. Areas covered: An overview of TD, unmet medical needs and current treatment guidelines are presented. The background, chemistry and clinical development of valbenazine to treat TD is detailed. A competitive market is developing as the treatment gap is identified and potential therapies are discussed in context of a broader market overview. Expert opinion: Antipsychotic use is growing among adults and children in the U.S. Consequently, prevalence of TD is expected to rise. Cessation of antipsychotics is often not possible as the psychiatric condition may deteriorate. Increasing doses of an antipsychotic to suppress involuntary movements is not sustainable long term as underlying TD worsens and movements typically recur. There were no FDA approved treatments for TD. The approval of valbenazine to treat TD is a critical step in addressing this gap in neurologic care.

Abstract
BACKGROUND/INTRODUCTION In this study, we investigated intellectual disability support professionals' knowledge and expectations towards effects of psychotropic drug use on behaviour and drug use in their clients, because shortcomings may lead to misinterpretations of behavioural symptoms and inappropriate drug use. METHODS Two self-designed questionnaires were used to measure the knowledge and expectations of 194 support professionals in 14 residential facilities regarding psychotropic drug use and effects of antipsychotics on behavioural, cognitive and mental functioning of people with intellectual disability. The psychometric properties of both questionnaires were adequate. RESULTS A majority of the professionals had unrealistic expectations regarding the positive effects of antipsychotics on cognitive and behavioural functioning, and 94% scored below the cut-off scores regarding knowledge; 60% indicated they needed education and training. CONCLUSIONS To achieve sufficient collaboration of intellectual disability support professionals in reducing inappropriate psychotropic drug use of clients, vocational educational training is needed.
