Exposure-Response Modeling in Adults and Adolescents With Schizophrenia to Support the Extrapolation of Brexpiprazole Efficacy to Adolescents

In order to accelerate drug development and avoid unnecessary drug trials in vulnerable pediatric populations, the US Food and Drug Administration (FDA) released a general advice letter to sponsors permitting the effectiveness of atypical antipsychotics for the treatment of schizophrenia in adults to be extrapolated to adolescents. Extrapolation is based on the evidence-based assumptions that (1) disease characteristics and (2) response to therapy, are similar in adults and adolescents. Whereas the FDA validated the extrapolation approach using data from multiple drug development programs, aripiprazole data are the most relevant to confirm the validity of the extrapolation approach for brexpiprazole, since aripiprazole and brexpiprazole both modulate dopaminergic and serotonergic signaling in the brain. The aims of this analysis were (1) to quantitatively assess the aripiprazole exposure (average steady-state concentration)-response (Positive and Negative Syndrome Scale total score change from baseline) similarity between adults and adolescents with schizophrenia, (2) to extend the aripiprazole exposure-response modeling to brexpiprazole using adult data, and (3) to use the brexpiprazole model to predict schizophrenia symptom response in adolescents. Disease-drug-dropout models were developed using patient-level data from clinical studies of aripiprazole (1007 adults, 294 adolescents) and brexpiprazole (1235 adults) in schizophrenia. The aripiprazole model demonstrated similar exposure-response between adults and adolescents with schizophrenia, validating the extrapolation approach. Extrapolation of the brexpiprazole adult exposure-response model to adolescents predicted the efficacy of brexpiprazole in adolescents aged 13-17 years with schizophrenia.

Consensus-based recommendations for the diagnosis and treatment of anxiety and depression in children and adolescents with epilepsy: A report from the Psychiatric Pediatric Issues Task Force of the International League Against Epilepsy

The Psychiatric Pediatric Issues Task Force of the International League Against Epilepsy (ILAE) aimed to develop recommendations for the diagnosis and treatment of anxiety and depression in children and adolescents with epilepsy. The Task Force conducted a systematic review and identified two studies that assessed the accuracy of four screening measures for depression and anxiety symptoms compared with a psychiatric interview. Nine studies met the eligibility criteria for treatment of anxiety and depressive disorders or symptoms. The risk of bias and certainty of evidence were assessed. The evidence generated by this review followed by consensus where evidence was missing generated 47 recommendations. Those with a high level of agreement (≥80%) are summarized. Diagnosis: (1) Universal screening for anxiety and depression is recommended. Closer surveillance is recommended for children after 12 years, at higher risk (e.g., suicide-related behavior), with subthreshold symptoms, and experiencing seizure worsening or therapeutic modifications. (2) Multiple sources of ascertainment and a formal screening are recommended. Clinical interviews are recommended whenever possible. The healthcare provider must always explain that symptom recognition is essential to optimize treatment outcomes and reduce morbidity. (3) Questioning about the relationship between symptoms of anxiety or depression with seizure worsening/control and behavioral adverse effects of antiseizure medications is recommended. Treatment: (1) An individualized treatment plan is recommended. (2) For mild depression, active monitoring must be considered. (3) Referral to a mental health care provider must be considered for moderate to severe depression and anxiety. (4) Clinical care pathways must be developed. (5) Psychosocial interventions must be tailored and age-appropriate. (6) Healthcare providers must monitor children with epilepsy who are prescribed antidepressants, considering symptoms and functioning that may not improve simultaneously. (7) Caregiver education is essential to ensure treatment adherence. (8) A shared-care model involving all healthcare providers is recommended for children and adolescents with epilepsy and mental health disorders. We identified clinical decisions in the management of depression and anxiety that lack solid evidence and provide consensus-based guidance to address the care of children and adolescents with epilepsy.

Predictive factors and symptom severity spectrum in adult schizophrenia: Potential insights for improved management and adequate care

Schizophrenia is one of the most disabling psychiatric disorders characterized by positive (hallucinations, delusions, formal thinking disorder) and negative symptoms (anhedonia, lack of speech and motivation). The present study aimed to identify the predictive factors of schizophrenia in adults, and potential differences in the environment of origin, sex, levels of occupational stress, intellectual level, marital status and age of onset of the disease depending on the severity of symptoms using analysis of data collected from 120 patients with a diagnosis of schizophrenia. The study was conducted at the 'Prof. Dr. Alexandru Obregia' Clinical Psychiatric Hospital in Bucharest and included adult patients hospitalized between March 2018 and January 2021 diagnosed with schizophrenia and evaluated by general clinical examination, psychiatric, neurological and psychological evaluation. Results revealed that robust predictors of mild and moderate symptoms were affective symptoms, heredo-collateral history of schizophrenia, late onset, the presence of positive and negative symptoms, substance abuse, stress and marital status, unmarried, lower IQ and mental deficiency. For moderate-severe and severe symptoms, predictors were affective symptoms, heredo-collateral history of schizophrenia and affective disorders, substance abuse, stress, borderline IQ and mild mental deficiency. The present results can be used for further development of psychopharmacological management of schizophrenia.

Prominently selective fluorescence approach with distinctive biopharmaceutical utility for analysis of lurasidone in human plasma and urine: Application to in vitro dissolution and content uniformity testing

A relevant approach based on the attractive inherited merits of fluorescence spectroscopy has been established for quantitative estimation of a newly approved second-generation atypical antipsychotic lurasidone (LUR) in its raw materials and pharmaceutical dosage forms. This study brings to light the strong native fluorescence of LUR at 400 nm in water after excitation at 316 nm. Different experimental parameters that may compromise the fluorescence of the drug were carefully investigated and optimized. A linear response was established between the relative fluorescence intensity and concentration over the concentration range of 50-650 ng/mL with excellent correlation (r = 0.9998). The validity of the method was evidenced in accordance with International Council for Harmonization guidelines, with minimal detection and quantification limits of 2.88 and 8.73 ng/mL, respectively. The method was effectively applied for the estimation of LUR in spiked human plasma and urine samples with acceptable recoveries. The biopharmaceutical significance of the method was heightened by its successful applications for both content uniformity and in vitro dissolution testing. Three different tools accredited the greenness character of the presented study. Eco-friendliness, effortlessness, and cost effectiveness are crucial hallmarks of our study. The presented study demonstrates potential applicability in quality control laboratories with limited resources.

Long-Acting Injectable Antipsychotic Initiation in Child and Adolescent Patients with Psychiatric Disorders

Objectives: There are currently no long-acting injectable antipsychotics (LAIAs) that are approved by the Food and Drug Administration for use in child and adolescent patients, however these agents are used off-label for the treatment of various psychiatric disorders. This study aims to describe the initiation and maintenance dosing strategies of LAIAs in child and adolescent psychiatry inpatients. Methods: This was a single-site retrospective chart review of patients less than 18 years of age initiated on an LAIA during an acute psychiatric hospitalization between October 1, 2015, and October 31, 2022. Patient demographics and hospital encounter information were collected and analyzed using descriptive statistics. Results: Of the 6402 unique pediatric patients discharged from the acute psychiatric hospital within the specified timeframe, 45 (0.7%) were newly initiated on an LAIA. The average age was 15.6 years (range 10-17), with a greater proportion of male (n = 26, 57.8%) and Black or African American (n = 27, 60%) patients. The LAIA agents prescribed included paliperidone palmitate (n = 21, 46.7%), aripiprazole monohydrate (n = 15, 33.3%), aripiprazole lauroxil (n = 7, 15.6%), haloperidol decanoate (n = 1, 2.2%), and risperidone microspheres (n = 1, 2.2%). Primary diagnosis via International Classification of Diseases-10 code at discharge included schizophrenia spectrum and other psychotic disorders (n = 19, 42.2%); bipolar disorder (n = 14, 31.1%); disruptive, impulse control, and conduct disorders (n = 6, 13.3%); autistic disorder (n = 5, 11.1%); and attention-deficit/hyperactivity disorder (n = 1, 2.2%). Seventeen patients (37.8%) received a loading dose regimen and/or a maintenance dose regimen that differed from adult package-insert dosing. The mean length of stay was 23.7 days, and 14 patients (31.1%) were readmitted to the psychiatric hospital within 6 months of discharge. The mean number of days to readmission was 71.9 days. Conclusions: This retrospective study is the first to focus on LAIA initiation and maintenance dosing strategies of multiple agents in both a child and adolescent patient population. Further research is required to evaluate the impact of LAIAs on clinical outcomes in this patient population.

A comparison of clinical characteristics and course predictors in early- and childhood-onset schizophrenia

AIM

The aim of this study was to compare the clinical characteristics of childhood-onset schizophrenia (COS) and early-onset schizophrenia (EOS) during the first- episode psychosis and the stable period, to examine psychopharmacological treatment approaches, and to investigate potential predictive factors for prognosis.

METHODS

Demographic, clinical, and psychopharmacological therapy data for 31 patients diagnosed with COS and 66 with EOS were retrieved from the file records in this multicenter study. Symptom distribution and disease severity and course were evaluated twice, in the acute psychotic stage and in the latest stable phase, during follow-up using the positive and negative syndrome scale (PANSS) and clinical global impression (CGI) scales.

RESULTS

A statistically significant difference was observed between the groups' CGI improvement rates and median last stable stage PANSS positive, negative, and general psychopathology symptom scores (p = .005, p = .031, p = .005, and p = .012, respectively). Premorbid neurodevelopmental disorder and obsessive-compulsive disorder and comorbidities were more common in the COS group (p = .025 and p = .030, respectively), and treatment required greater multiple antipsychotic use in that group (p = .013). When the independent variables affecting the difference between pre- and post-treatment PANSS scores were examined using linear regression analysis, the model established was found to be statistically significant (F = 5.393; p = .001), and the group variable (p = .024), initial disease severity (p = .001), and socioeconomic level (p = .022; p = .007) emerged as predictive factors for the disease course.

CONCLUSION

Although early diagnosis and treatment is an important factor in improving prognosis in schizophrenia, more specific predictors for schizophrenia need to be identified. Additionally, preventive programs and pharmacological methods need to be developed in children with neurodevelopmental problems, particularly those from low socioeconomic status families.

Utilization of Head Imaging in Children and Adolescents With First-Episode Psychosis: A Retrospective Analysis

Background Psychotic disorders are commonly diagnosed in the mid-20s but symptoms often emerge earlier during late teenage years to mid-20s. Notably, studies have shown that psychotic symptoms can also affect younger individuals, with a higher prevalence among preteens than teens. Head imaging via computed tomography (CT) or magnetic resonance imaging (MRI) can be performed to rule out non-psychiatric causes of psychotic symptoms in this population but may pose additional risks and financial burdens. Practice patterns vary regarding when to utilize head imaging in pediatric patients with first-episode psychosis (FEP). The purpose of this study is to better understand the use of head imaging in pediatric FEP and associated patient characteristics. Methods A retrospective cohort study was performed. Eligible patients were <18 years of age with an encounter documented between 2013 and 2023 where a diagnosis code for psychosis was first applied. Medical records were manually reviewed if head imaging was performed during the index encounter or within one month. Descriptive statistics were used to report the study population demographics. Independent t-testing was used to compare characteristics between patients who did and did not receive head imaging. Results A total of 113 patients met the inclusion criteria for the study, of which 12 (10.6%) received head imaging within the specified timeframe. All received CT criteria head scans, and a significantly higher proportion were African American or Black when compared to those who did not receive head imaging (10/12 (83.3%) vs. 53/101 (52.5%) p=0.023). None of the imaging tests performed yielded significant neurological findings that suggested an underlying pathology for psychosis. Conclusions Head imaging was rarely utilized for the initial assessment of pediatric FEP in this study. When it was used, CT head scans were the modality of choice but did not yield any remarkable findings to suggest a non-psychiatric cause of psychotic symptoms. This adds to the body of evidence supporting a conservative approach when considering head imaging in pediatric FEP.

Trends and off-label utilization of antipsychotics in children and adolescents from 2016 to 2021 in China: a real-world study

BACKGROUND

Global antipsychotic usage, including off-label prescriptions, has increased in recent decades. However, trends in China, particularly for children and adolescents, remain unclear. This study explored these trends from 2016 to 2021 and identified factors associated with off-label prescriptions.

METHODS

In this retrospective study, we analyzed on-label and off-label prescriptions based on drug information approved by the China National Medical Products Administration. To identify factors associated with off-label prescriptions, we conducted multivariate logistic regression analysis.

RESULTS

Our study included 48,258 antipsychotic prescriptions, 52.4% (25,295) of which were prescriptions for males. Of these, 61.7% (29,813) were off-label. Over time, the number of antipsychotics and the percentage of off-label prescriptions for children and adolescents overall increased from 2016 to 2021. The use of atypical antipsychotics increased, whereas that of typical antipsychotics decreased. For off-label usage, all of the factors in our study were associated with off-label usage, including age, sex, year, region, department, reimbursement, antipsychotic type, drug expense, number of polypharmacy and diagnoses. Additionally, tiapride (15.8%) and aripiprazole (18.6%) were the most common typical and atypical antipsychotics, respectively. For pediatric diseases, common diagnoses included mood or affective disorders (31.7%) and behavioral and emotional disorders, with onset usually occurring in childhood and adolescence (29.1%). Furthermore, a depressive state was the most common diagnosis for which antipsychotic polypharmacy was used for treatment.

CONCLUSION

In this retrospective study, off-label antipsychotic prescriptions were common, with trends generally increasing among children and adolescents from 2016 to 2021. However, there is a lack of evidence supporting off-label usage, thus emphasizing the need for studies on the efficacy and safety of these treatments.

Challenging Case: New-Onset Hallucinations and Developmental Regression in a Child with Autism Spectrum Disorder

CASE

Nick is a 5-year-old boy who began displaying self-stimulating behaviors and decreased social interactions shortly before turning 3 years. At the age of 3.5 years, he was diagnosed with autism spectrum disorder by a local developmental-behavioral pediatrician. His parents recall that the physician described Nick to be "high functioning" and encouraged them to expect that he would attend college and live independently as an adult. Upon receiving the diagnosis, intervention was initiated using an applied behavioral analysis (ABA) approach. With this intervention, he demonstrated initial gains in the use of complex language and improved social interactions.Concerns regarding suspected psychosis emerged just before starting kindergarten when Nick began experiencing ego-dystonic visual and auditory hallucinations. Initially, Nick verbally responded to the hallucinations and vividly described what he was experiencing. Shortly after the onset of these hallucinations, Nick experienced a significant decrease in the frequency and complexity of his expressive language and became more withdrawn. Over time, his hallucinations intensified, and his parents became increasingly fearful for his safety. Various antipsychotic and mood-stabilizing medications, steroids, and immunotherapy have been trialed with limited improvement of his symptoms.An extensive medical evaluation yielded the following:1. Magnetic resonance imaging of the brain: dilated perivascular spaces.2. Urine organic acids: ketosis and increased lactic acid.3. Antinuclear antibody: minimally positive.4. Vitamin B12: elevated.All other studies, including lumbar puncture, electroencephalogram (awake and asleep), genetic studies (chromosomal microarray, fragile X testing, and whole exome sequencing), metabolic studies, inflammatory markers, and thyroid panel, were negative/normal.Nick is enrolled in a special education classroom within a school that utilizes an ABA-based approach for all students. As part of his educational programming, he receives 25 hours of ABA in a 1:1 setting, 2 hours of speech therapy, 3 hours of occupational therapy, 1 hour of physical therapy, and 30 minutes of music therapy weekly. Current concerns include significant head-banging and thrashing before falling asleep, hyperactivity, unsafe behaviors (e.g., banging on windows, climbing high to reach desired items), aggression toward caregivers, limited ability to complete self-care tasks (e.g., personal hygiene, toileting), significant decline in expressive language, and continued response to internal stimuli.Nick's parents now present to a multidisciplinary center seeking guidance regarding additional therapies/interventions to assist in management of his current developmental and behavioral challenges as well as information regarding his expected developmental trajectory as he reaches adulthood.

Identification and treatment of individuals with childhood-onset and early-onset schizophrenia

Approximately 8 % of patients with schizophrenia are diagnosed before age 18, and 18 % experience their first symptoms before age 18. This narrative review explores the management of patients with early-onset schizophrenia (EOS) and childhood-onset schizophrenia (COS) from diagnosis to their transition to adult care settings. Early diagnosis of schizophrenia in children and adolescents is essential for improving outcomes, but delays are common due to overlapping of symptoms with developmental phenomena and other psychiatric conditions, including substance use, and lack of clinicians' awareness. Once diagnosed, antipsychotic treatment is key, with specific second-generation agents generally being preferred due to better tolerability and their broader efficacy evidence-base in youth. Dosing should be carefully individualized, considering age-related differences in drug metabolism and side effect liability. Clinicians must be vigilant in detecting early non-response and consider switching or dose escalation when appropriate. Since early age of illness onset is a consistent risk factor for treatment-resistant schizophrenia (TRS), clinicians need to be competent in diagnosing TRS and using clozapine. Since COS and EOS are associated with cognitive deficits and impaired functioning, psychosocial interventions should be considered to improve overall functioning and quality of life. Good long-term outcomes depend on continuous treatment engagement, and successful transitioning from pediatric to adult care requires careful planning, early preparation, and collaboration between pediatric and adult clinicians. Targeting functional outcomes and quality of life in addition to symptom remission can improve overall patient well-being. Comprehensive evaluations, age-specific assessments, and targeted interventions are needed to address the unique challenges of EOS and COS.

Sex differences in prevalence and clinical correlates of internet addiction among Chinese adolescents with schizophrenia

BACKGROUND

Patients with schizophrenia (SCZ) exhibit sex differences in various aspects, and patients with SCZ have a high prevalence of internet addiction (IA). However, sex differences in IA among patients with SCZ mostly remain unstudied, particularly in Chinese adolescent patients with SCZ. This study investigated sex differences in prevalence, risk factors, and clinical correlates of IA among Chinese adolescent patients with SCZ.

METHODS

A total of 706 adolescent patients with SCZ were enrolled in this study using a cross-sectional design and a convenience sampling method. Demographics and clinical data of the patients were collected using a standardized clinical assessment form. The Positive and Negative Syndrome Scale (PANSS) and the Young's Internet Addiction Test were used to evaluate psychopathological symptoms and IA respectively.

RESULTS

Overall, the prevalence of IA among Chinese adolescent patients with SCZ was 26.30% (95% CI: 23.09-29.60%). In Chinese adolescents with SCZ, there was a sex difference in the comorbidity of IA (males: 33.33% vs. females: 21.69%). Binary logistic regression analysis showed that IA was significantly predicted by good socioeconomic status in male and female patients with SCZ. City of living and PANSS total score were associated with IA in male patients with SCZ. In contrast, hospitalization rate and depression score were associated with IA in female patients with SCZ.

CONCLUSION

Our study suggests sex differences in clinical correlates of IA in Chinese adolescent patients with SCZ. An additional longitudinal study is required to confirm the findings of the present study.

A case report of LAI two injection start in a 16-year-old adolescent with severe manic episode and comorbid cannabinoid use disorder

There is a lack of randomized clinical trials and few studies regarding long-acting injectable antipsychotics (LAIs) in adolescents. Non-adherence, aggressiveness, comorbid substance use disorder and lack of insight may represent the main reasons for starting LAIs. Hereby we describe a 16-year-old male adolescent subject with bipolar type I disorder and comorbid cannabinoid use disorder, successfully treated with two-injection start regimen of LAI aripiprazole. Two-injection start regime of aripiprazole could represent an effective and safe therapeutic option for adolescents with early onset bipolar disorder.

Comparison of long-acting injectable antipsychotics with oral antipsychotics and hospital readmission rates in pediatric patients

Introduction

Studies indicate that long-acting injectable antipsychotics (LAIAs) reduce the risk of relapse and hospitalization compared with oral antipsychotics (APs) in adults. Oral formulations of APs are well-studied in the pediatric population, but little is known regarding the off-label use of LAIAs in this population.

Methods

This retrospective chart review evaluated readmission rates for pediatric patients admitted to a psychiatric ward in a large academic hospital between January 1, 2015, and December 1, 2022, requiring AP therapy. The experimental group included patients initiated on LAIA therapy, and the control group included patients initiated on a new oral AP. Patients were matched by several clinical factors.

Results

Each group consisted of 38 patients. For the primary outcome, hospital readmission rates at 3 months, the LAIA group had a 13.2% readmission rate compared with 26.3% in the comparator group (p = .153). In months 4 through 6, there was a 5.3% versus 15.8% readmission rate, respectively (p = .139). In months 7 through 12, it was 7.9% versus 18.4% (p = .179). There were significantly fewer cumulative readmissions at the 1-year mark in the LAIA group (N = 9, 23.7%) compared with the oral AP group (N = 18, 47.4%) (p = .031). No statistically significant differences were seen in hospital length of stay although results numerically favored LAIA.

Discussion

In a pediatric population, the administration of an LAIA when compared with the oral equivalent resulted in numerically fewer hospital readmissions, decreased length of stay, and fewer adverse effects, but these effects were not statistically significant except for cumulative readmissions at 1 year.

Prodromal symptoms and the duration of untreated psychosis in first episode of psychosis patients: what differences are there between early vs. adult onset and between schizophrenia vs. bipolar disorder?

To assess the role of age (early onset psychosis-EOP < 18 years vs. adult onset psychosis-AOP) and diagnosis (schizophrenia spectrum disorders-SSD vs. bipolar disorders-BD) on the duration of untreated psychosis (DUP) and prodromal symptoms in a sample of patients with a first episode of psychosis. 331 patients with a first episode of psychosis (7-35 years old) were recruited and 174 (52.6%) diagnosed with SSD or BD at one-year follow-up through a multicenter longitudinal study. The Symptom Onset in Schizophrenia (SOS) inventory, the Positive and Negative Syndrome Scale and the structured clinical interviews for DSM-IV diagnoses were administered. Generalized linear models compared the main effects and group interaction. 273 AOP (25.2 ± 5.1 years; 66.5% male) and 58 EOP patients (15.5 ± 1.8 years; 70.7% male) were included. EOP patients had significantly more prodromal symptoms with a higher frequency of trouble with thinking, avolition and hallucinations than AOP patients, and significantly different median DUP (91 [33-177] vs. 58 [21-140] days; Z = - 2.006, p = 0.045). This was also significantly longer in SSD vs. BD patients (90 [31-155] vs. 30 [7-66] days; Z = - 2.916, p = 0.004) who, moreover had different profiles of prodromal symptoms. When assessing the interaction between age at onset (EOP/AOP) and type of diagnosis (SSD/BD), avolition was significantly higher (Wald statistic = 3.945; p = 0.047), in AOP patients with SSD compared to AOP BD patients (p = 0.004). Awareness of differences in length of DUP and prodromal symptoms in EOP vs. AOP and SSD vs. BD patients could help improve the early detection of psychosis among minors.

Immune and oxidative stress biomarkers in pediatric psychosis and psychosis-risk: Meta-analyses and systematic review

OBJECTIVE

While genetic and cohort studies suggest immune and reduction/oxidation (redox) alterations occur in psychosis, less is known about potential alterations in children and adolescents.

METHODS

We conducted a systematic review to identify immune and redox biomarker studies in children and adolescents (mean age ≤ 18 years old) across the psychosis spectrum: from psychotic like experiences, which are common in children, to threshold psychotic disorders like schizophrenia. We conducted meta-analyses when at least three studies measured the same biomarker.

RESULTS

The systematic review includes 38 pediatric psychosis studies. The meta-analyses found that youth with threshold psychotic disorders had higher neutrophil/lymphocyte ratio (Hedge's g = 0.40, 95 % CI 0.17 - 0.64), tumor necrosis factor (Hedge's g = 0.38, 95 % CI 0.06 - 0.69), C-reactive protein (Hedge's g = 0.38, 95 % CI 0.05 - 0.70), interleukin-6 (Hedge's g = 0.35; 95 % CI 0.11 - 0.64), and total white blood cell count (Hedge's g = 0.29, 95 % CI 0.12 - 0.46) compared to youth without psychosis. Other immune and oxidative stress meta-analytic findings were very heterogeneous.

CONCLUSION

Results from several studies are consistent with the hypothesis that signals often classified as "proinflammatory" are elevated in threshold pediatric psychotic disorders. Data are less clear for immune markers in subthreshold psychosis and redox markers across the subthreshold and threshold psychosis spectrum. Immune and redox biomarker intervention studies are lacking, and research investigating interventions targeting the immune system in threshold pediatric psychosis is especially warranted.

Temporal trends in antipsychotic prescriptions for pediatric patients using an administrative hospital database in Japan: a retrospective study

BACKGROUND

Schizophrenia is a psychiatric disorder characterized by hallucinations, delusions, and other symptoms. Although treatment guidelines for schizophrenia have been established in Japan, drugs are not recommended for pediatric schizophrenia. Additionally, the temporal trends in prescribing antipsychotics for pediatric patients with schizophrenia are unclear. Therefore, we aimed to clarify the trends in antipsychotic prescriptions for Japanese pediatric outpatients from 2015 to 2022.

METHODS

Administrative data (as of November 2023) of Japanese pediatric outpatients with schizophrenia aged 0-18 years who visited acute-care diagnosis procedure combination hospitals between January 1, 2015, and December 31, 2022, were included in this study. The target drugs for schizophrenia were all indicated for treating schizophrenia and marketed in Japan as of December 2022. Annual prescription trends for antipsychotics during this period were calculated based on their proportions. The Cochran-Armitage trend test was used to evaluate the proportion of prescriptions for each antipsychotic.

RESULTS

The main drugs prescribed for these patients were aripiprazole and risperidone. Among male patients, the proportion of prescriptions for aripiprazole increased significantly from 21.2% in 2015 to 35.9% in 2022, whereas that for risperidone decreased significantly from 47.9% in 2015 to 36.7% in 2022 (both P < 0.001). Among female patients, the proportion of prescriptions for aripiprazole increased significantly from 21.6% in 2015 to 35.6% in 2022, whereas that for risperidone decreased significantly from 38.6% in 2015 to 24.8% in 2022 (both P < 0.001).

CONCLUSIONS

Aripiprazole and risperidone were primarily prescribed for pediatric schizophrenia in Japan during the study period. Additionally, the proportion of aripiprazole prescriptions increased over time.

Initiation of Aripiprazole Lauroxil Long-Acting Injectable in Adolescents During Hospitalization: A Case Series

Objective: The efficacy and safety of long-acting injectable (LAI) antipsychotics in the pediatric population is not well established due to limited evidence. This case series aims to describe off-label use of aripiprazole lauroxil (AL) LAI in adolescent inpatients, including findings on safety and readmission trends. Methods: This was a retrospective chart review of patients who were initiated on AL LAI while admitted at a county-based adolescent psychiatric unit between March 2021 and March 2023. Data comprised sociodemographic and clinical characteristics, such as psychiatric diagnoses, prior antipsychotic trials, and history of nonadherence. Other observations of interest included tolerability of AL LAI and time to readmission. Results: This analysis identified 12 adolescents who received AL LAI within a 2-year period. The mean age was 16 ± 1 years, and seven (58%) patients were female. There were varying primary psychiatric diagnoses, with the most common being bipolar disorder (25%), schizophrenia (17%), major depressive disorder with psychotic features (17%), and unspecified mood disorder (17%). Eleven (92%) patients had previously trialed at least one antipsychotic, with seven (58%) having exposure to oral aripiprazole before admission. Nonadherence was the driving factor for LAI consideration in all but one patient. AL LAI was well tolerated short term; one patient reported experiencing injection site pain, and one patient discontinued the LAI after discharge due to anxiety. Time to readmission ranged from 15 to 658 days for seven patients who were hospitalized again; two of the readmissions occurred within 1 month. Conclusion: This is the first case series to describe initiation of AL LAI at an inpatient adolescent psychiatric unit. Our study illustrates that AL LAI may hold potential as an acceptably tolerated treatment in adolescents with varying psychiatric diagnoses. Further studies are needed to evaluate long-term safety and effectiveness of AL LAI in youth.

A new scale for the screening of childhood early psychotic symptoms

This study aimed to develop a new scale, the Early Psychotic Symptoms screening scale (EPSy), to assess the prodromes of psychotic symptoms in children aged 4 to 13 years. Two versions were proposed: one to assess the child's current behavior and one to assess the child's behavior when he/she was 2 years old. The second aim of this study was to investigate the presence of these symptoms at the age of 2 years and their evolution up to the child's current age. The analysis of EPSy identified three main factors, namely mistrust/paranoia, perceptual aberrations/hallucinations and disorganized symptoms. It has good psychometric properties. Data also shows that, independently of the participant's age, the total score on the 2-years-old version predicts the total score on the current-age version, and this is also the case for each individual factor. Finally, it is of clinical interest since it makes it possible to describe symptomatology both at age 2 and at the child's present age depending on the group to which the children are assigned (control children, psychotic children, non-psychotic children).

Electroconvulsive therapy or clozapine for adolescents with treatment-resistant schizophrenia: an explorative analysis on symptom dimensions

OBJECTIVE

This study sought to compare pre-intervention patient characteristics and post-intervention outcomes in a naturalistic sample of adolescent inpatients with treatment-resistant psychotic symptoms who received either electroconvulsive therapy (ECT) or clozapine.

METHODS

Data of adolescents with schizophrenia/schizoaffective disorder receiving ECT or clozapine were retrospectively collected from two tertiary-care psychiatry-teaching university hospitals. Subscale scores of the Positive and Negative Symptom Scale (PANSS) factors were calculated according to the five-factor solution. Baseline demographics, illness characteristics, and post-intervention outcomes were compared.

RESULTS

There was no significant difference between patients receiving ECT (n = 13) and clozapine (n = 66) in terms of age, sex, and the duration of hospital stay. The ECT group more commonly had higher overall illness and aggression severity. Smoking was less frequent in the clozapine group. Baseline resistance/excitement symptom severity was significantly higher in the ECT group, while positive, negative, affect, disorganisation, and total symptom scores were not. Both interventions provided a significant reduction in PANSS scores with large effect sizes.

CONCLUSION

Both ECT and clozapine yielded high effectiveness rates in adolescents with treatment-resistant schizophrenia/schizoaffective disorder. Youth receiving ECT were generally more activated than those who received clozapine.

Practitioner Review: Psychosis in children and adolescents

Psychotic symptoms, including hallucinations, delusions, and disorganized thinking and behaviors, are the hallmarks of schizophrenia; but may also present in the context of other psychiatric and medical conditions. Many children and adolescents describe psychotic-like experiences, which can be associated with other types of psychopathology and past experiences (e.g., trauma, substance use, and suicidality). However, most youth reporting such experiences do not have, nor will ever develop, schizophrenia or another psychotic disorder. Accurate assessment is critical because these different presentations have different diagnostic and treatment implications. For this review, we focus primarily on the diagnosis and treatment of early onset schizophrenia. In addition, we review the development of community-based first-episode psychosis programming, and the importance of early intervention and coordinated care.

Adherence to antipsychotic laboratory monitoring guidelines in children and youth: a population-based study

Background

In 2011, the Canadian Alliance for Monitoring Effectiveness and Safety of Antipsychotics in Children (CAMESA) published guidelines for the metabolic monitoring of antipsychotic-treated children and youth. Population-based studies examining adherence to these guidelines are needed to ensure the safe use of antipsychotics in children and youth.

Methods

We conducted a population-based study of all Ontario residents aged 0 to 24 who were newly dispensed an antipsychotic between April 1, 2018, and March 31, 2019. We estimated prevalence ratios (PRs) and 95% confidence intervals (CI) associating sociodemographic characteristics with the receipt of baseline and follow-up (3- and 6-month) laboratory testing using log-Poisson regression models.

Results

Overall, 6,505 of 27,718 (23.5%) children and youth newly dispensed an antipsychotic received at least one guideline-recommended baseline test. Monitoring was more prevalent among individuals aged 10 to 14 years (PR 1.20; 95% CI 1.04 to 1.38), 15 to 19 years (PR 1.60; 95% CI 1.41 to 1.82), and 20 to 24 years (PR 1.71; 95% CI 1.50 to 1.94) compared to children under the age of 10. Baseline monitoring was associated with mental health-related hospitalizations or emergency department visits in the year preceding therapy (PR 1.76; 95% CI 1.65 to 1.87), a prior diagnosis of schizophrenia (PR 1.20; 95% CI 1.14 to 1.26) or diabetes (PR 1.35; 95% CI 1.19 to 1.54), benzodiazepine use (PR 1.13; 95% CI 1.04 to 1.24), and receipt of a prescription from a child and adolescent psychiatrist or developmental pediatrician versus a family physician (PR 1.41; 95% CI 1.34 to 1.48). Conversely, monitoring was less frequent in individuals co-prescribed stimulants (PR 0.83; 95% CI 0.75 to 0.91). The prevalence of any 3- and 6-month follow-up monitoring among children and youth receiving continuous antipsychotic therapy at these time points was 13.0% (1,179 of 9,080) and 11.4% (597 of 5,261), respectively. Correlates of follow-up testing were similar to those of baseline monitoring.

Conclusion

Most children initiating antipsychotic therapy do not receive guideline-recommended metabolic laboratory monitoring. Further research is needed to understand reasons for poor guideline adherence and the role of clinician training and collaborative service models in promoting best monitoring practices.

Schizophrenia among young people first admitted to psychiatric inpatient care during early and middle adolescence

OBJECTIVE

This study explored the incidence and stability of schizophrenia in a large national register data of all adolescents first admitted to psychiatric inpatient care at ages 13-17 in Finland 1980-2010.

METHODS

The study population (N 17,112) comprised all Finnish citizens aged 13-17 receiving their first ever psychiatric inpatient treatment between 1980 and 2010 in Finland. To explore incidence and stability of schizophrenia, the diagnostic information on inpatient care or disability pension was obtained from the appropriate registers.

RESULTS

The incidence of schizophrenia disorders (F20 + F25) during adolescence was higher in the study population for those admitted to psychiatric inpatient care 1980-1989 than in other decades examined. Overall, psychiatric inpatient care during adolescence was a risk factor for subsequent schizophrenia, especially if a diagnosis of F20-29 was set although a considerable share of those with psychotic disorders other than schizophrenia diagnosis did not subsequently convert to schizophrenia. The stability of adolescent onset schizophrenia diagnosis was high.

CONCLUSION

Adolescents requiring psychiatric inpatient care have a higher later rate of schizophrenia diagnosis than prevalence at community level. Whereas adolescent onset schizophrenia diagnosis is a fairly stable diagnosis, there are other adolescent psychotic disorders which are more transient in nature.

Editorial: Can Less Be More When Measuring Psychotic Symptoms in Youth?

There is a strong tradition in child mental health of developing measures to assess both general psychopathology and specific constructs such as attention-deficit/hyperactivity disorder, autism, depression, anxiety, and obsessive-compulsive disorder. For psychosis, however, the tendency has been to use in children instruments that were developed for adults, such as the Positive and Negative Syndrome Scale (PANSS). There are general good reasons for using the same assessment tools in youth as in adults, because this facilitates comparisons across the lifespan. In the case of schizophrenia, in particular, there is evidence of continuity of psychopathology from adolescence to adulthood. There are also practical reasons why an instrument such as the PANSS, which has been widely used in research and accepted by drug regulatory agencies, has remained unchanged over time. The PANSS has consistently been shown to be able to discriminate between antipsychotic medication and placebo in adults, children, and adolescents.^1,2 Keeping the same rating instrument across studies and over time also facilitates comparisons between clinical trials and medications, allows possible time trends in treatment effect to be detected, and helps systematic reviews and meta-analyses.^1,2 The drawback of this methodological conservatism is that it provides little motivation to perfect the existing tools for measuring psychopathology, with negative impact on both research and clinical practice.

What Role for Long-Acting Injectable Antipsychotics in Managing Schizophrenia Spectrum Disorders in Children and Adolescents? A Systematic Review

BACKGROUND

Long-acting injectable antipsychotics (LAIAs) are an efficacious and well-tolerated treatment in adults with schizophrenia spectrum disorders (SSD). However, there is less evidence for their use in children and adolescents.

OBJECTIVES

The aim of this systematic review was to summarize findings regarding the effectiveness and side effects of LAIA in children and adolescents with SSD.

METHODS

Four databases (Web of Science, PubMed, MEDES, and Dialnet) were systematically searched for articles published between inception and 12 March, 2022, with the following inclusion criteria: (1) original articles or case reports; (2) providing data on efficacy/effectiveness or safety/tolerability of LAIA treatment in children and adolescents diagnosed with SSD (schizophrenia, schizoaffective disorder, schizophreniform disorder, non-affective psychotic disorder); (3) mean age of samples ≤ 18 years; and (4) written in English or Spanish. Exclusion criteria were review articles, clinical guides, expert consensus as well as posters or oral communication in conferences. The risk of bias was assessed using the ROBIS tool.

RESULTS

From 847 articles found, 13 met the inclusion criteria. These included seven single case reports or case series, four retrospective chart reviews, a 24-week open-label trial, and one observational prospective study, covering a total of 119 adolescents (aged 12-17 years) with SSD. Almost all the articles described data on second-generation LAIA (53 patients on risperidone [once every other week], 33 on paliperidone palmitate [once monthly], 10 on aripiprazole [once monthly], and two on olanzapine pamoate [once monthly]). Twenty-one patients were reported to be only on first-generation LAIAs. Non-adherence was the main reason for starting an LAIA. In all of the studies, the use of LAIAs was associated with improvement in the patients' symptoms.

CONCLUSIONS

There are few studies assessing the use of LAIAs in adolescents with SSD. Overall, these treatments have suggested good effectiveness and acceptable safety and tolerability. However, we found no studies examining their use in children aged < 12 years. The problems and benefits linked to this type of antipsychotic formulation in the child and adolescent population require further study, ideally with prospective, controlled designs.

Weight Gain During Antipsychotic Treatment in Children, Adolescents, and Adults: A Disproportionality Analysis in the Global Pharmacovigilance Database, Vigibase®

INTRODUCTION

While antipsychotic-induced weight gain has been widely described in adults, it has yet to be better characterized in children and adolescents.

OBJECTIVE

The aim of this study was to assess antipsychotic-induced weight-gain reporting in children and adolescents as compared to adults, and according to the type of antipsychotic.

METHODS

The study is an observational, case-non-case study using individual case safety reports from the WHO global pharmacovigilance database VigiBase^® from 1 January 2000 to 2 June 2021. Disproportionality in antipsychotic-related weight-gain reporting in children and adolescents compared to adults was evaluated based on reporting odds ratios (RORs) with corresponding 95% confidence intervals (CIs) through multivariate logistic regression modeling. Analysis was adjusted for sex, region of reporting, year of notification, reporter qualification, concomitant use of antidepressants, and use of more than one antipsychotic.

RESULTS

Among 282,224 antipsychotic-related spontaneous reports included in this analysis, we identified 16,881 (6.0%) weight-gain cases. Disproportionality in weight-gain reporting was found in children (adjusted ROR (aROR) 3.6; 95% CI 3.3-3.8) and in adolescents (aROR 2.3; 95% CI 2.2-2.4) compared to adults. Use of risperidone was associated with the highest increase in weight-gain reporting in children (aROR 4.9; 95% CI 3.9-6.1) and adolescents (aROR 3.6; 95% CI 3.1-4.1).

CONCLUSIONS

Compared to adults, weight-gain reporting with antipsychotics was disproportionally higher in the pediatric population, especially in children under 12 years of age. Considering the impact of weight gain on global morbidity and mortality, physicians should closely monitor weight gain in young patients, especially children on risperidone.

Diagnostic profiles in adolescence and emerging adulthood: Transition patterns and risk factors

INTRODUCTION

Complex diagnostic profiles (i.e., clusters of comorbid disorders) may be present in adolescence with long-lasting effects later in life. Little is known about their developmental transitions to adulthood as well as potential risk factors. This study aimed to identify the diagnostic profiles in adolescence and emerging adulthood, patterns of transitions and risk factors.

MATERIAL AND METHODS

A sample of 1062 Mexican adolescents (43.22% men, M=14.19 years at baseline, SD=1.68) was assessed for psychiatric disorders at adolescence and emerging adulthood. Latent class analysis was used to identify diagnostic profiles. Profile transition was studied using multi-state modeling between the life periods. Logistic regression was utilized to study risk factor influence on profile development in adulthood.

RESULTS

Three diagnostic profiles (i.e., minimal disorder/no-psychopathology; and two clinical profiles: internalizing and externalizing) were identified in both periods. Anxiety disorders were the most frequent psychiatric presentation in adolescence, while depression was the most prevalent disorder in adulthood. More than 15% of participants showed a clinical profile regardless life period. Comorbidity was present in 57% of participants with a clinical psychiatric profile. Finally, common (suicidal behavior) and specific risk factors (sex, parents' education and income) predicted transitions to profiles from adolescence to emerging adulthood.

CONCLUSIONS

Psychiatric disorders are frequently observed adopting a complex diagnostic profile in both adolescence and emerging adulthood. Comorbidity seems to be common in both life periods. Developmental issues and comorbidity should be considered for health service provision and treatment choice.

Electroconvulsive Treatment Utilization for Inpatient Management of Catatonia in Adolescents With Schizophrenia Spectrum Disorders

OBJECTIVE

The aim of this study was to determine rates of electroconvulsive therapy (ECT) use for catatonia in schizophrenia spectrum disorders, stratified by patient demographics and hospital characteristics, and its impact on inpatient length of stay and cost.

METHODS

We found 155 adolescents (aged 12-18 years) with principal discharge diagnosis of schizophrenia spectrum disorders with catatonia from the National Inpatient Sample. They were subgrouped into ECT (n = 20) and non-ECT (n = 135) groups. We used descriptive statistics to evaluate the utilization of ECT for catatonia and independent-sample t test for continuous variables with statistical significance at P ≤ 0.05.

RESULTS

The overall utilization rate of ECT in adolescents for catatonia was 12.9%. A high rate of ECT use was evident for Whites (30.8%) compared with the other race/ethnicities and also was seen in private health insurance beneficiaries (20%). The rate of ECT use varied by the region, with highest for the Northeast (20%), followed by the South (18.2%), and the West (14.3%). Adolescent inpatients with catatonia in public and teaching type, and large bed-size hospitals were more likely to receive ECT than their counterparts. The mean number of ECT sessions required during the inpatient stay was 5.2 (range, 1-15), and the mean number of days from admission to initial ECT was 2.5 (range, 0-6).

CONCLUSIONS

Electroconvulsive therapy is used for approximately only 13% of adolescents with catatonia when comorbid schizophrenia spectrum disorders are present, suggesting that many patients may not get evidence-based treatment. Future studies in this area are needed.

Pharmacokinetics, Safety, and Tolerability of Cariprazine in Pediatric Patients with Bipolar I Disorder or Schizophrenia

Objective: Cariprazine is a dopamine D₃-preferring D₃/D₂ and serotonin 5-HT_1A receptor partial agonist approved to treat adults with schizophrenia and manic/mixed or depressive episodes associated with bipolar I disorder. This sequential-cohort, dose-escalation study was the first to evaluate the pharmacokinetic, safety, and tolerability profile of cariprazine and its two major active metabolites, desmethyl-cariprazine (DCAR) and didesmethyl-cariprazine (DDCAR), in pediatric patients with schizophrenia or bipolar I disorder. Methods: This phase I open-label study enrolled patients with schizophrenia (13-17 years of age) or bipolar I disorder (10-17 years of age). Patients met the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for schizophrenia or bipolar I disorder and had Positive and Negative Syndrome Scale (PANSS) total scores ≥70 or Young Mania Rating Scale (YMRS) total scores ≥20. Patients were assigned to one of four treatment groups to receive 6 weeks of cariprazine treatment through slow titration to 1.5, 3, or 4.5 mg/d or fast titration to 4.5 mg/d. Pharmacokinetics, adverse events (AEs), and various safety parameters were analyzed. Efficacy was evaluated as an exploratory outcome. Results: A total of 50 participants were enrolled. Based on mean trough levels, steady state appeared to be reached within 1-2 weeks for cariprazine and DCAR and within 4-5 weeks for DDCAR. Systemic exposure of cariprazine, DCAR, and DDCAR generally increased approximately in proportion to the increases in dose from 1.5 to 4.5 mg/d. The most frequent treatment-related, treatment-emergent AEs included sedation, parkinsonism, tremor, dystonia, and blurred vision. Improvements from baseline on the PANSS and YMRS were observed throughout treatment. Conclusion: In this first investigation of cariprazine in a pediatric population with schizophrenia or bipolar disorder, pharmacokinetic parameters were consistent with those observed in adults. Cariprazine appeared to be safe and tolerable in children and adolescents.

Catatonic conundrum

Differentiating between physical and psychological causes of confusion and psychosis poses a significant challenge to clinicians across all disciplines of medicine. This case report explores the clinical presentation and diagnostic journey of an adolescent girl. She presented to the emergency department with acutely altered behaviour and went on to re-present on multiple occasions over the following months with symptoms suggestive of psychosis. The team faced diagnostic difficulty differentiating between organic and non-organic causes of altered behaviour and mental state. This article explores the challenge faced by the team during the assessment and diagnosis of this patient.

Efficacy, Tolerability, and Acceptance of Long-Lasting Antipsychotics in Children and Adolescents: A Systematic Review

Objectives: While long-lasting antipsychotics (LLA) were specifically developed to address the problem of adherence in patients with chronic psychiatric disorders, their role in pediatric populations is not clear. Methods: To document the efficacy, tolerance, and acceptance of LLAs in children and adolescents, a literature search was conducted using several databases for published studies (PubMed, PsycINFO) from January 1965 to December 2020. Twenty-two studies were identified (16 case reports/series, 3 open label studies, 2 controlled studies, and 1 retrospective analysis of national database). Results: Demographic features were widely heterogeneous across studies (total N = 480, 58% male, mean age = 15.0 ± 1.8). Case reports/series presented positive therapeutic outcomes in noncompliant youths with severe mental illness. Three open-label one-arm studies supported the clinical efficacy of risperidone long-acting injection in patients previously stabilized with oral risperidone. One study showed lower clinical symptoms and higher functioning at 12 months in youths treated for an acute psychotic episode with paliperidone palmitate compared to oral risperidone. The types and rates of side effects of LLA were comparable to those observed for oral antipsychotics. Two studies suggested better metabolic and neurological tolerance of LLA compared to an oral form. Preliminary evidence supported a satisfactory level of treatment satisfaction in patients treated with LLA and their families, while concerns were raised regarding practical administration in outpatient services. However, the average quality of the evidence based on the RoB2 tool was low. Conclusions: The level of evidence was low for the efficacy of LLA in pediatric populations and very low for the tolerance and acceptance. It concerned mostly the effect of risperidone long-acting injection in adolescents with psychotic disorders. Randomized maintenance clinical trials using noninferiority analysis would be more appropriate for further research.

Pharmacological Treatment of Early-Onset Schizophrenia: A Critical Review, Evidence-Based Clinical Guidance and Unmet Needs

Early-onset schizophrenia (EOS) – onset before age 18 – is linked with great disease burden and disability. Decision-making for EOS pharmacological treatment may be challenging due to conflicting information from evidence and guidelines and unidentified care needs may remain unmet.

We searched for systematic reviews, meta-analyses and umbrella reviews of EOS pharmacological treatment published in PubMed over the past 10 years and selected five clinical guidelines from Europe, North-America and Australia. Based on predefined outcomes, we critically compared the evidence supporting EOS-approved drugs in Europe and/or North-America with guidelines recommendations. We also evaluated the coverage of these outcomes to identify unmet needs.

One systematic review, nine meta-analyses and two umbrella reviews (k=203 trials, N=81,289 participants, including duplicated samples across selected articles) were retrieved. Evidence supported the efficacy of aripiprazole, clozapine, haloperidol, lurasidone, molindone, olanzapine, quetiapine, risperidone and paliperidone in EOS, all of which obtained approval for EOS either in Europe and/or in North-America. Cognition, functioning and quality of life, suicidal behaviour and mortality and services utilisation and cost-effectiveness were poorly covered/uncovered.

Among the antipsychotics approved for EOS, aripiprazole, lurasidone, molindone, risperidone, paliperidone and quetiapine emerged as efficacious and comparably safe options. Olanzapine is known for a high risk of weight gain and haloperidol for extrapyramidal side-effects. Treatment-resistant patients should be offered clozapine. Future long-term trials looking at cognition, functioning, quality of life, suicidal behaviour, mortality, services utilisation and cost-effectiveness are warranted. Closer multi-agency collaboration may bridge the gap between evidence, guidelines and approved drugs.

Association of NKAPL rs1635 With Cognitive Function in Early-Onset Schizophrenia

BACKGROUND: Schizophrenia is a severe mental disorder with high heritability, and cognitive dysfunction is one of the core features. Growing evidence suggests the genetic risk of schizophrenia may contribute to cognitive impairments. The variant rs1635 (nucleotide sequence: c.455C>A; amino acid sequence: T152N) located on the (NFKB activating protein like) NKAPL gene confers risk for schizophrenia and might play a role in the neurodevelopmental process, which is particularly relevant to cognitive function. However, the relationship between rs1635 and cognitive function remains unclear.

METHODS: A total of 130 patients with early-onset schizophrenia (EOS) and 300 patients with adult-onset schizophrenia (AOS) of Han Chinese were recruited and underwent neurocognitive tests by using the MATRICS Consensus Cognitive Battery (MCCB). The NKAPL rs1635 was genotyped by using DNA sequencing. The peripheral blood NKAPL mRNA expression level was examined in 152T or 152N carriers (n = 20) in EOS patients, by using the qRT-PCR. The phosphorylation level of NAKPL T152N polymorphism was detected by cell experiments. In utero electroporation of mouse embryos was examined to explore the effect of Nkapl on neuronal migration.

RESULTS: Compared with rs1635 AA and AC carriers, CC (the CC genotype encodes the protein NKAPL-152T) carriers of EOS patients performed better in cognitive domain of speed of processing (t = 2.644, p = 0.009), trail making test (t = 2.221, p = 0.028) and category fluency (t = 2.578, p = 0.011). However, patients with AOS exhibited no significant differences in seven domains among the three genotype groups. There were no significant differences in cognitive performance between EOS and AOS. In EOS patients, NKAPL mRNA level in NKAPL-152N carriers is significantly lower than that of NKAPL-152T carriers. The phosphorylation level of NKAPL-152N is significantly decreased compared to NKAPL-152T. In utero electroporation showed that Nkapl deletion impairs the embryonic radial migration process.

CONCLUSION: The present study found that NKAPL rs1635 was associated with cognitive impairments and peripheral blood mRNA expression level in EOS patients. The NKAPL full-length protein is required for embryonic cortical neuronal migration. The phosphorylation level of NKAPL-152N is significantly decreased. The NKAPL T152N may affect the NAKPL mRNA expression level and embryonic cortical neuronal migration by regulating the NAKPL protein phosphorylation. These data suggest that NKAPL rs1635 affects cognitive function by regulating early brain development in early-onset schizophrenia.

Low Rates of Clinician Monitoring for Second Generation Antipsychotic Medications in Community Pediatric Practice

Second generation antipsychotic (SGA) medications are frequently prescribed to pediatric patients in the United States. This retrospective observational study sought to ascertain the extent of adherence to established pediatric SGA monitoring guidelines in community practice. The team used the electronic health record to determine clinician adherence to SGA monitoring guidelines at baseline, 12-week, and annual times relative to prescribing an SGA. At the time of their SGA prescription, 5.5% of pediatric patients had received all of the orders according to the monitoring guidelines. Annually, 2.5% of patients had received the necessary orders to completely adhere to monitoring guidelines; 42% of patients received no monitoring orders. Monitoring was more likely for children who had multiple types of providers and interacted with the healthcare system beyond a traditional office visit. This research informs healthcare providers about the gap between prescribing and monitoring for SGA medications in community practice for pediatric populations.

Improving screening methods for psychosis in an adolescent help-seeking population using the Child Behavior Checklist (CBCL) and the Youth Self Report (YSR) versus the Prodromal Questionnaire -16 items version (PQ-16)

BACKGROUND

Screening methods for detecting Ultra High Risk status (UHR) or psychosis should be improved, especially in adolescent samples. We therefore tested whether the Child Behavior Checklist (CBCL) and the Youth Self Report (YSR) add value to the Prodromal Questionnaire-16 items version (PQ-16) for detecting UHR status or psychosis.

METHODS

We included help-seeking adolescents who had completed the PQ-16, YSR, CBCL, and a Comprehensive Assessment of an At Risk Mental States (CAARMS) interview, and used independent samples t-tests and binary logistic regression analyses to determine the scales contributing to the prediction of UHR status or of having reached the psychosis threshold (PT). Cutoff scores were determined using ROC analyses.

RESULTS

Our sample comprised 270 help-seeking adolescents (mean age 14.67; SD 1.56, range 12-17); 67.8% were girls and 66.3% were of Dutch origin. The Thought Problems syndrome scales of both the YSR and the CBCL best predicted UHR or PT, and had screening values comparable to the PQ-16. Other syndrome scales did not improve screening values. Although combining measures reduced the number of false negatives, it also increased the number of adolescents to be interviewed. The best choice was to combine the YSR Thought Problems scale and the PQ-16 as a first-step screener.

CONCLUSIONS

Combining measures improves the detection of UHR or PT in help-seeking adolescents. The Thought Problems subscales of the YSR and CBCL can both be used as a first-step screener in the detection of UHR and/or psychosis. Trial registration Permission was asked according to the rules of the Ethics Committee at Leiden. This study is registered as NL.44180.058.13.

Comparative Efficacy and Tolerability of Antipsychotics for Juvenile Psychotic Disorders: A Systematic Review and Network Meta-Analysis

BACKGROUND

Psychotic disorders produce important morbidity and disability in children and adolescents. There have been few relevant treatment trials, encouraging assessment of research aimed at testing efficacy and safety of antipsychotics for juveniles. We aimed to compare the short- and long-term efficacy and safety of antipsychotics to treat psychotic disorders among children and adolescents.

METHODS

Four major bibliographic databases (PubMed, MEDLINE, PsycINFO, and EMBASE) were searched for clinical trials of antipsychotics in children or adolescents, from database inception to May 2021. We searched for clinical trials comparing antipsychotics with control conditions for juvenile psychosis based on blinded review by 2 independent investigators (C.S.Y. and M.L.). We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses and applied the Cochrane risk-of-bias tool to appraise study quality. One reviewer (A.B.) performed data abstraction which was confirmed by 2 independent, blinded reviewers (C.S.Y. and M.L.). Primary outcomes were scores rating psychosis symptoms and dichotomized retention in treatment protocols versus dropouts because of adverse events. Effect sizes were pooled using frequentist random-effects network meta-analysis modeling to generate summary rate ratios (RRs) and Cohen d standardized mean differences.

RESULTS

Systematic searching generated 1330 unique records. Of these, short-term (n = 15, for 6 [3-12] weeks) and long-term (n = 10, for 12 [6-60] months) treatment trials involved 2208 (39.2% females; median age, 15.3 years), and 1366 subjects (35.0% females; median age, 15.6 years), respectively. Short-term reduction of psychosis scores ranked clozapine (d = -1.35; 95% confidence interval [CI], -1.97 to -0.73]), molindone (-1.22; 95% CI, -1.68 to -0.75), olanzapine (-1.12; 95% CI, -1.44 to -0.81), and risperidone (-0.93; 95% CI, -1.22 to -0.63) as the most effective agents. In longer-term treatment, only lurasidone was effective. Clozapine (RR, 12.8) and haloperidol (RR, 5.15) led to more all-cause and adverse event-related dropouts. There were few trials/drug (1 each for aripiprazole, asenapine, lurasidone, molindone, paliperidone, and ziprasidone, short term; aripiprazole, clozapine, haloperidol, lurasidone, and molindone, long-term). Heterogeneity and inconsistency were high, especially in long-term trials, without evidence of publication bias.

CONCLUSIONS

Some antipsychotics were effective and tolerated short term, but longer-term evidence was very limited. The overall paucity of trials and of adequate controls indicates that more well-designed randomized controlled trials are required for adequate assessment of antipsychotic drug treatment for juveniles.

Treatment Approaches for First Episode and Early-Phase Schizophrenia in Adolescents and Young Adults: A Delphi Consensus Report from Europe

PURPOSE

Although first-episode psychosis (FEP) in youth, particularly early-onset schizophrenia (EOS), is managed similarly to adult-onset schizophrenia, few antipsychotics are approved for people aged 13-18 years. We aimed to explore areas of uncertainty in EOS management and provide evidence-based recommendations to mental health specialists. We used the Delphi methodology to gain knowledge in areas lacking evidence-based strategies. This standardized methodology consists of the development of a questionnaire by content experts, which is then submitted to a broader panel of professionals (panelists) to survey their level of agreement on the topics proposed.

MATERIALS AND METHODS

The developed questionnaire covered patient management from diagnosis to maintenance treatment and was administered to a broader panel of specialists across Europe. Based on an analysis of responses received in this first round, the items that needed further insight were submitted to the panel for a second round and then reanalysed.

RESULTS

An initial set of 90 items was developed; in round I, consensus was reached for 83/90 items (92%), while it was reached for 7/11 (64%) of the items sent out for rerating in round II. Feedback for rounds I and II was obtained from 54/92 and 48/54 approached experts, respectively. There was broad agreement on diagnostic standards, multimodal approaches and focus on adverse events, but uncertainty in terms of pharmacological strategies (including clozapine) in case of failure and antipsychotic dosing in younger patients.

CONCLUSION

Despite knowledge about diagnostic clues and integrated management of EOS, this study highlights the lack of standardization in treating EOS, with safety arguments having a major role in the decision-making process. Targeted clinical trials and systematic dissemination across Europe of current scientific evidence on the value of early intervention services is hoped to contribute to standardized and improved quality care for patients with early-phase psychosis and schizophrenia.

Safety and effectiveness of lurasidone in adolescents with schizophrenia: results of a 2-year, open-label extension study

BACKGROUND

Minimal long-term benefit: Risk data are available regarding antipsychotic treatments for schizophrenia in pediatric populations. This study evaluated the long-term safety, tolerability, and effectiveness of lurasidone in adolescents with schizophrenia.

METHODS

Patients aged from 13 to 17 who completed 6 weeks of double-blind (DB), placebo-controlled treatment with lurasidone were enrolled in a 2-year, open-label (OL), flexible dose (20-80 mg/day) lurasidone treatment study. Safety was assessed via spontaneous reporting, rating scales, body weight measurement, metabolic, and prolactin testing. Effectiveness measures included the Positive and Negative Syndrome Scale (PANSS) total score.

RESULTS

About 271 patients completed 6 weeks of DB treatment and entered the 2-year OL extension study. Altogether, 42.4% discontinued prematurely, 10.7% due to adverse events. During OL treatment, the most common adverse events were headache (24.0%); anxiety (12.9%), schizophrenia, and nausea (12.5%); sedation/somnolence (12.2%); and nasopharyngitis (8.9%). Minimal changes were observed on metabolic parameters and prolactin. Mean change from DB baseline in weight at week 52 and week 104 was +3.3 kg and + 4.9 kg, respectively, compared to an expected weight gain of +3.4 kg and + 5.7 kg, respectively, based on the sex- and age-matched US Center for Disease Control normative data. Continued improvement was observed in PANSS total score, with mean change from OL baseline of -15.6 at week 52 and -18.4 at week 104.

CONCLUSION

In adolescents with schizophrenia, long-term lurasidone treatment was associated with minimal effects on body weight, lipids, glycemic indices, and prolactin. Continued improvement in symptoms of schizophrenia was observed over 2 years of lurasidone treatment.

Efficacy and Safety of Blonanserin Oral Tablet in Adolescents with Schizophrenia: A 6-Week, Randomized Placebo-Controlled Study

Objectives: To evaluate the short-term efficacy and safety of blonanserin in adolescents with schizophrenia. Methods: This 6-week multicenter, double-blind, randomized, placebo-controlled study investigated fixed-dose blonanserin (8 or 16 mg/day) in patients 12-18 years of age diagnosed with schizophrenia, as indicated by a Positive and Negative Syndrome Scale (PANSS) total score of 60-120 and a Clinical Global Impressions-Severity score of ≥3. The primary endpoint was change from baseline to week 6 in the PANSS total score, using a mixed model for repeated measures analysis. Safety was assessed by the incidence and severity of adverse events (AEs). Results: Among 151 randomized patients, 150 were included in the primary analysis population. Demographic and clinical characteristics were similar across groups at baseline. The rate of study discontinuation was 14.9%, 23.5%, and 28.3% in patients administered with placebo, blonanserin 8 mg/day, and blonanserin 16 mg/day, respectively. The least-squares mean change (95% confidence interval [CI]) from baseline to week 6 in PANSS total score was -10.6 (-16.10 to -5.10), -15.3 (-20.80 to -9.86), and -20.5 (-25.89 to -15.16) in patients administered placebo, 8 mg/day blonanserin, and 16 mg/day blonanserin, respectively. The 16-mg/day blonanserin group showed significantly greater reduction in the PANSS total score than the placebo group (least-squares mean difference [95% CI]: -9.9 [-17.61 to -2.25], p = 0.012, effect size: 0.538), although the 8-mg/day group showed no significant difference. The incidence of AEs such as akathisia, somnolence, and hyperprolactinemia was higher in the blonanserin groups than in the placebo group. AEs associated with blonanserin were generally mild and were consistent with its known profile in adults with schizophrenia. Conclusions: Blonanserin achieved a sufficient efficacy in adolescent patients, and the safety profile was similar to that in adults, which suggests that blonanserin may be a safe treatment option for adolescents with schizophrenia.

Long-Term Safety and Efficacy of Blonanserin Oral Tablet in Adolescents with Schizophrenia: A 52-Week, Multicenter, Open-Label Extension Study

Objectives: To evaluate the long-term efficacy and safety/tolerability of oral blonanserin in adolescents with schizophrenia (Study registration number: JapicCTI-111725). Methods: This 52-week, multicenter, open-label extension study enrolled adolescent patients with schizophrenia who opted to enter in this study after the completion of the preceding placebo-controlled study. Blonanserin tablet was orally administered twice daily, after morning and evening meals, for 52 weeks using dose-titration method within a range between 4 and 24 mg/day. The primary end point was the change from baseline to the end of the study in the Positive and Negative Syndrome Scale (PANSS) total score. Safety/tolerability was assessed by the incidence and severity of adverse events. Results: Of 117 patients who completed the preceding placebo-controlled study, 109 entered this extension study and 43 (39.4%) of them discontinued the study treatment. The safety analysis set comprised 106 patients who received the study drug at least once, including 36 and 70 patients treated with placebo (DB-placebo group) and blonanserin tablet (DB-blonanserin group), respectively, in the placebo-controlled study. At the last assessment, the mean change in PANSS total score overall [mean (standard deviation)] was -24.9 (20.76) from the baseline of the placebo-controlled study, which was similar in the DB-placebo and DB-blonanserin groups. The overall incidence of adverse events was 90.6%, and most of them were mild or moderate in severity, with similar incidence of extrapyramidal symptoms (38.7%) to that in adults receiving long-term blonanserin oral tablet treatment and minimal change in weight and metabolic parameters. Conclusions: This long-term extension study showed that 52 weeks of oral blonanserin treatment improved or stabilized psychiatric symptoms in patients with adolescent schizophrenia. There were no major issues with the safety or tolerability of blonanserin administration in this study. Considering relatively less adverse effects on weight increase and metabolic parameters, blonanserin is expected to be a safe/tolerable treatment option for adolescent schizophrenia that can be used seamlessly from adolescence to adulthood.

Clozapine for Management of Childhood and Adolescent-Onset Schizophrenia: A Systematic Review and Meta-Analysis

Background: Schizophrenia at a young age deserves investigation because of the greater severity and burden of illness on individuals and health care than its adult onset. For this study, we included both childhood-onset schizophrenia and early-onset schizophrenia. We used the common term "childhood and adolescent-onset schizophrenia (CAOS)" for either type. This systematic review provides an overview of the clinical use, efficacy, and safety of clozapine treatment in managing CAOS. Methods: We conducted a systematic literature search in PubMed, Embase, and PsycINFO databases. We searched for randomized controlled trials (RCTs), open-label studies (OLSs), review articles, meta-analytic and observational studies. Our literature search resulted in 1242 search results. After the title, abstract, and full article review, 18 studies qualified (double-blind RCTs n = 4; OLS n = 4; observational studies n = 7; case reports n = 3). Results: Clozapine use in CAOS was generally well tolerated and not associated with any fatalities. Clozapine use in the short term (6 weeks) and long term (2-9 years) was superior in efficacy than other antipsychotics in CAOS management. Improvement in overall symptoms was maintained during long-term follow-up over the years in OLSs. Clozapine appeared to have a favorable clinical response and shorter hospital stays. Sedation and hypersalivation were commonly reported (90%), constipation was next in frequency (13%-50%). Neutropenia was seen in 6%-15% of cases and agranulocytosis (<0.1%). Although weight gain was common (up to 64%), followed by metabolic changes (8%-22%), treatment-onset diabetes was less frequent (<6%). Akathisia, tachycardia, and blood pressure changes were less commonly seen. Conclusions: Limited studies indicate that clozapine is a safe and efficacious option for CAOS management. We need large-scale and well-designed long-term RCTs for the use of clozapine in the management of CAOS.

Metabolic events associated with the use of antipsychotics in children, adolescents and young adults: a multinational sequence symmetry study

It is known that younger patients treated with antipsychotics are at increased risk of metabolic events; however, it is unknown how this risk varies according to ethnicity, the class of antipsychotic and the specific product used, and by age group. We conducted a multinational sequence symmetry study in Asian populations (Hong Kong, Japan, Korea, Taiwan and Thailand) and non-Asian populations (Australia and Denmark) to evaluate the metabolic events associated with antipsychotics in both Asian and non-Asian populations, for typical and atypical antipsychotics, and by the subgroups of children and adolescents, and young adults. Patients aged 6-30 years newly initiating oral antipsychotic drugs were included. We defined a composite outcome for metabolic events which included dyslipidemia, hypertension and hyperglycemia. We calculated the sequence ratio (SR) by dividing the number of people for whom a medicine for one of the outcome events was initiated within a 12-month period after antipsychotic initiation by the number before antipsychotic initiation. This study included 346,904 antipsychotic initiators across seven countries. Antipsychotic use was associated with an increased risk of composite metabolic events with a pooled adjusted SR (ASR) of 1.22 (95% CI 1.00-1.50). Pooled ASRs were similar between Asian (ASR, 1.22; 95% CI 0.88-1.70) and non-Asian populations (ASR, 1.22; 95% CI 1.04-1.43). The pooled ASR for typical and atypical antipsychotics was 0.98 (95% CI 0.85-1.12) and 1.24 (95% CI 0.97-1.59), respectively. No difference was observed in the relative effect in children and adolescents compared to young adults. The risk of metabolic events associated with antipsychotics use was similar in magnitude in Asian and non-Asian populations despite the marked difference in drug utilization patterns.

Altered White Matter Integrity at Illness Onset in Adolescents With a First Episode of Psychosis

BACKGROUND

Disruption in white matter integrity has been consistently observed in individuals with psychosis. However, whether such abnormalities are already present at illness onset or are related to downstream processes remains elusive. The study of adolescents with a recent onset of psychosis provides the opportunity to evaluate white matter integrity proximally to disease onset.

METHODS

Twenty-six adolescents (aged 15.9 ± 1.3 years) with a first episode of psychosis (FEP) (less than 6 months duration) were compared with 26 age and sex-matched healthy controls (HC) (16.8 ± 2 years). In participants with a FEP, clinical diagnoses were confirmed after a minimum of 1 year follow-up (main categories: schizophrenia, bipolar disorder, or schizoaffective disorder). Anatomical images and diffusion tensor sequences were acquired using a 1.5T scanner. Whole brain, voxel-wise group differences in fractional anisotropy (FA) were investigated between participants with a FEP and controls.

RESULTS

Relative to HC, FEP participants displayed decreased FA in the right posterior cingulate gyrus, encompassing the right superior and posterior corona radiata, and the right parahippocampal gyrus, including the cingulum and fornix. FEP patients showed no areas of increased FA relative to HC. The results remained significant after controlling for medication, cannabis use and intelligence.

CONCLUSION

Our findings indicate that adolescents with recent onset of psychotic disorders show decreased white matter integrity in circuits implicated in cognitive functions and emotion regulation.

Patterns of Care for Adolescent With Schizophrenia: A Delphi-Based Consensus Study

BACKGROUND

The current conceptualization of schizophrenia as neurodevelopmental disorder should lead to innovative public health policies in terms of a reorganization of the mental health care systems, particularly in the transition from adolescence to adulthood, to reduce personal, familiar, and social costs and burdens. The purpose of the project was to perform a survey among a panel of Italian schizophrenia experts, to share evidence-based information on adolescent schizophrenia and explore the degree of consensus among professionals in the following four macro-areas: early diagnosis; pharmacological treatment; health care system organization and transition process from adolescent to adulthood; and psychosocial interventions.

METHODS

The consensus process consisted of a two-step web-based Delphi method, which took place between June and November 2021. The survey was developed by a panel of four psychiatrists and four child neuropsychiatrists, identified as key opinion leaders (KOLs). The KOLs identified 21 statements involving a total of 70 items with a major need of clarification on early-onset schizophrenia (EOS). The survey was distributed to 86 specialists in psychiatry and child neuropsychiatry.

RESULTS

The results revealed a large agreement among the expert group on all the investigated areas of adolescent schizophrenia patterns of care and management. Consensus was ultimately reached for 67 items of the Delphi survey (95.7%), while negative consensus was reached for 2 items and no consensus was reached for 1 item.

CONCLUSIONS

Overall, results showed a significant gap between the acquired scientific knowledge and clinical practice. In this scenario, it should be necessary to plan specific initiatives at a multiple level, to edit recommendations on clinical decision-making, as well as to prompt changes at the political and organizational levels, also involving scientific societies, patients, and family associations, to overcome the barriers that delay the implementation process.

Long-term use of antidepressants, mood stabilizers, and antipsychotics in pediatric patients with a focus on appropriate deprescribing

It is estimated that 8% to 12% of youth are prescribed psychotropic medications. Those in foster care, juvenile justice systems, residential treatment facilities, and with developmental or intellectual disabilities are more likely to be prescribed high-risk regimens. The use of psychotropic medications in this age group is often off-label and can be associated with significant risk, warranting critical evaluation of their role. Landmark trials, pediatric-specific guidelines, and state-driven initiatives play critical roles in supporting evidence-based use of psychotropic medications in children. Overall, there is a lack of literature describing the long-term use of psychotropic medications in youth—particularly with regard to neurobiological, physical, and social changes that occur throughout development. Deprescribing is an important practice in child and adolescent psychiatry, given concerns for over-prescribing, inappropriate polytherapy, and the importance of reevaluating the role of psychotropic medications as children develop.

Relationship between cognition and age at onset of first-episode psychosis: comparative study between adolescents, young adults, and adults

Psychotic disorders typically manifest from late adolescence to early adulthood, and an earlier onset might be associated with greater symptom severity and a worse long-term prognosis. This study aimed to compare the cognitive characteristics of patients with first-episode psychosis (FEP) by their age at onset. We included 298 patients diagnosed with FEP and classified them as having an early onset (EOS), youth onset (YOS), or adult onset (AOS) based on age limits of ≤ 18 years (N = 61), 19-24 years (N = 121), and ≥ 25 years (N = 116), respectively. Socio-demographic and clinical variables included age at baseline, gender, socio-economic status, antipsychotic medication, DSM-IV diagnoses assessed by clinical semi-structured interview, psychotic symptom severity, and age at onset. Neuropsychological assessment included six cognitive domains: premorbid intelligence, working memory, processing speed, verbal memory, sustained attention, and executive functioning. The EOS group had lower scores than the YOS or AOS groups in global cognition, executive functioning, and sustained attention. Although the scores in the YOS group were intermediate to those in the EOS and AOS groups for most cognitive factors, no statistically significant differences were detected between the YOS and AOS groups. Age at onset results in specific patterns of cognitive interference. Of note, impairment appears to be greater with EOS samples than with either YOS or AOS samples. A longitudinal study with a larger sample size is needed to confirm our findings.

Schizophrenia population health management: perspectives of and lessons learned from population health decision makers

BACKGROUND: Despite therapeutic advances for patients with schizophrenia, improving patient outcomes and reducing the cost of care continue to challenge formulary decision makers. OBJECTIVES: To (1) understand the perspectives of formulary decision makers on challenges to optimal schizophrenia population management and (2) identify best practices and recommendations for mitigating these challenges. METHODS: This mixed-methods study, conducted in a double-blind manner, comprised in-depth telephone interviews with formulary decision makers from February through May 2020, and a web-based follow-on survey that was sent to all participants in October 2020. US-based formulary decision makers were recruited if they were directly involved in schizophrenia drug formulary or coverage decision making for national or regional payers, health systems, or behavioral health centers. Formulary decision makers' perceptions of challenges, policies, and programs related to schizophrenia population health management were assessed generally and in the context of the COVID-19 pandemic. RESULTS: 19 formulary decision makers participated in the interviews and 18 (95%) completed the survey. Participants reported a spectrum of patient- and payer-driven challenges in schizophrenia population health management, including medication nonadherence, high pharmacy and medical costs, and frequent hospitalizations and emergency department visits. Participants noted that COVID-19 had worsened all identified challenges, although patient unemployment (mean score of 2.00 on a scale of 1 [made much worse] to 5 [made much better]) and reduced access to psychiatric care (mean score, 2.12) were most negatively affected. The most common strategies implemented in order to improve schizophrenia population health management included case management (89%), telemedicine (83%), care coordination programs (72%), strategies to mitigate barriers to accessing medication (61%), and providing nonmedical services to address social determinants of health (56%). Participants noted that, ideally, all treatments for schizophrenia would be available on their formularies without utilization management policies in place in order to increase accessibility to medication, but cost to the health plans made that difficult. Whereas 61% of respondents believed that long-acting injectable antipsychotics (LAIs) were currently underused in their organizations, only 28% represented organizations with open access policies for LAIs. Participants believed that among patients with schizophrenia, LAIs were most beneficial for those with a history of poor or uncertain adherence to oral medications (mean score of 4.50 on a scale of 1 [not at all beneficial] to 5 [extremely beneficial]) and those with recurring emergency department visits and inpatient stays (mean score, 3.94). Study participants reported slightly increased use of LAIs (mean score of 3.17 on a scale of 1 [negatively impacted] to 5 [positively impacted]) among their patients with schizophrenia in response to the COVID-19 pandemic; 29% of participants reported easing access restrictions for LAIs. CONCLUSIONS: Participants described persisting challenges and various approaches intended to improve schizophrenia population health management. They also recommended strategies to optimize future health management for this population, including expanding programs to address social determinants of health and mitigating barriers to accessing treatment.
