Abstract
OBJECTIVE To investigate the association between atomoxetine or methylphenidate use and arrhythmia, heart failure (HF), stroke, and myocardial infarction (MI) in attention-deficit/hyperactivity disorder (ADHD) patients mainly focused on the people of working age. METHODS In a self-controlled case series study using a Japanese claims database, we identified events of arrhythmia, HF, stroke, and MI among 15,472 atomoxetine new users and 12,059 methylphenidate new users. Adjusted incidence rate ratios (aIRRs) of outcome events were estimated using multivariable conditional Poisson regression. RESULTS An increased risk of arrhythmia was observed during the first 7 days after the initial atomoxetine exposure (aIRR 6.22, 95% CI [1.90, 20.35]) and in the subsequent exposure (3.23, [1.58, 6.64]). No association was found between methylphenidate exposure and arrhythmia, nor between atomoxetine or methylphenidate exposure and HF. The limited number of stroke and MI cases prevented thorough analysis. CONCLUSIONS Clinicians should consider monitoring for arrhythmia after patients initiating or re-initiating atomoxetine.

Front Psychiatry 2024; 14:1289157. [PMID: 38250274 PMCID: PMC10796544 DOI: 10.3389/fpsyt.2023.1289157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 12/12/2023] [Indexed: 01/23/2024] Open
Abstract
The diagnosis of attention-deficit hyperactivity disorder (ADHD) is based on the presence of pervasive, persistent symptoms of inattention and/or hyperactivity/impulsivity typically emerging early in life and resulting in significant functional impairment. In contrast to a worldwide epidemiological prevalence of approximately 5% in children and 2-3% in adults, there are significant variations in the prevalence of administrative ADHD diagnoses and medication use. We assert that in order to explore the underlying dynamics of this phenomenon, a thorough understanding of the construct ADHD is necessary. We contend that ADHD is not a natural entity that unfolds within an individual and can be understood independent from societal and environmental factors, but rather that ADHD as a diagnosis can better be conceptualized as a valid and pragmatically useful social construct. Decisions to diagnose and treat ADHD should follow a person-centered approach and be focused on functional impairment within a socially constructed, context-dependent and environmentally contingent model.

Abstract
This study documented the prescribing patterns of methylphenidate and atomoxetine among patients aged 3 to 18 in Taiwan diagnosed with attention deficit hyperactivity disorder (ADHD) between 2004 and 2017. Initial treatment for ADHD, the time between the first diagnosis and the first prescription, and medication-switching patterns were investigated. The final cohort consisted of 256,882 patients, and 147,210 (57.3%) of them received medication treatment. Most of the patients (98.2%) received methylphenidate. Atomoxetine use increased from 0.1% in 2007 to 5.5% in 2017. The median time between the ADHD diagnosis and the first prescription was 21 days (IQR: 0-212 days). In patients who initiated methylphenidate, 12,406 (8.4%) patients switched to atomoxetine; 850 (31.3%) of the children began with atomoxetine and switched to methylphenidate. In conclusion, methylphenidate was the predominant treatment for ADHD in 2004-2017. However, the prevalence of pharmacotherapy for ADHD was relatively low. Further investigation on the reasons behind this pattern is recommended.

Abstract
BACKGROUND Osmotic release oral system methylphenidate (OROS-MPH) is one of the most commonly used medication for attention-deficit hyperactivity disorder (ADHD), however, real-world knowledge on OROS-MPH dose titration has been limited. This study aims to summarize and visualise the OROS-MPH titration patterns in children and adolescents with ADHD in the United States (US) and Japan. METHODS This retrospective cohort study used the US IBM® MarketScan® Commercial Claims and Encounters database from 2000 to 2019 and the Japan Medical Data Centre database from 2008 to 2019. New OROS-MPH users with ADHD were identified and split into child (6 to < 13 years) and adolescent (13 to < 18 years) groups according to age at OROS-MPH initiation/reinitiation. Patient characteristics and OROS-MPH treatment patterns were described. OROS-MPH dose titration pathways were visualised by Sankey diagrams. RESULTS We included 98,973 children and 62,002 adolescents in the US cohort, and 4595 children and 1508 adolescents in the Japanese cohort. In Japanese cohort, 91.9% of children and 77.9% of adolescents initiated OROS-MPH at the lowest dose (18 mg/day), whereas US patients had a broader distribution of initial doses (e.g., 18-54 mg/day). The US patients had higher daily dose of OROS-MPH than Japanese patients. Overall, a minority (< 40%) of the OROS-MPH users underwent dose titration, and different titration patterns were observed between the US and Japanese patients. CONCLUSIONS Different treatment and titration patterns of OROS-MPH were observed in the two countries. Additional real-world studies about clinical reasoning underlying dose selection are needed to support clinical decision-making.

Abstract
CONTEXT ADHD is the most common mental disorder in school-aged children. In France, methylphenidate is the only drug authorized for ADHD. Here, we describe the pattern of ADHD diagnosis and methylphenidate prescription to children and adolescents from 2010 to 2019. METHODS We conducted a retrospective cohort study of all beneficiaries of the French general health insurance scheme (87% of the population, 58 million people). We extracted information for all children and adolescents aged 0-17 years who received: (1) A diagnosis of ADHD (34,153 patients). (2) At least one methylphenidate prescription (144,509 patients). We analyzed the clinical, demographic, institutional, and social parameters associated with ADHD diagnosis and methylphenidate consumption in France. RESULTS The ADHD diagnosis among children and adolescents increased by 96% between 2010 and 2019. ADHD diagnosis affects more boys than girls. About 50.6% of children hospitalized with a diagnosis of ADHD in 2017 also had another psychiatric diagnosis. The rate of children hospitalized with an ADHD diagnosis and treated with MPH varied between 56.4 and 60.1%. The median duration of MPH treatment for a 6-year-old ADHD child initiated in 2011 is 7.1 years. In 2018, 62% of ADHD children were receiving at least one psychotropic medication. Between 2010 and 2019, methylphenidate prescription increased by +56% for incidence and +116% for prevalence. The prevalence of methylphenidate prescription reached between 0.61 and 0.75% in 2019. Boys are predominantly medicated. The median duration of treatment among 6-year-olds in 2011 was 5.5 years. The youngest children received the longest treatment duration. Diagnoses associated with methylphenidate prescription did not always correspond to the marketing authorization. Among children receiving the first prescription of methylphenidate, 22.8% also received one or more other psychotropic drugs during the same year. A quarter of initiations and half of renewals were made outside governmental recommendations. Educational and psychotherapeutic follow-up decreased from 4.1% in 2010 to 0.8% in 2019. French children and adolescents, who were the youngest in their class were more likely to be diagnosed (55%) and prescribed methylphenidate (54%). Children from disadvantaged families had an increased risk of ADHD diagnosis (41.4% in 2019) and methylphenidate medication (25.7% in 2019).

Abstract
Aim To assess label compliance in prescription of medications approved for treatment of attention‐deficit/hyperactivity disorder (ADHD) in Japan at the time of this study: methylphenidate (MPH), atomoxetine, and guanfacine. Methods Retrospective descriptive study was conducted in prevalent‐user cohorts from the Japan Medical Data Center database. Patients who were prescribed a study drug between January 1, 2013 and September 30, 2018 and were in the database for ≥30 days were included. A prescription was considered compliant if all 4 criteria were satisfied: appropriate age, daily dose not exceeding the approved maximum, no contraindicated concurrent medications, and no contraindicated conditions. Results Among 17 418 patients who were prescribed a study drug during 2013‐2018, 73% were male and 53% were children (aged <18 years). Fewer than 2% of prescriptions were for patients outside the approved age, 10%‐13% of patients in the atomoxetine and MPH cohorts received ≥1 prescription exceeding maximum approved dose, no patients were co‐prescribed a contraindicated medication, and 16%–18% of patients in the MPH cohorts had ≥1 contraindicated condition. During their first 500 days of use, for approximately 73%‐86% of patients, all prescriptions were compliant with all label requirements. Conclusions Among patients exposed to ADHD medications in Japan during 2013‐2018, nearly all prescriptions for these medications were label‐compliant for age. For >85% of patients, all prescriptions were label‐compliant for dose, and for approximately 80%, all prescriptions were label‐compliant for contraindicated conditions. We did not find evidence of widespread abuse or noncompliant use of prescribed ADHD medications. To assess label compliance in prescription of medications approved for the treatment of ADHD in Japan at the time of this study (2013‐2018), a retrospective descriptive cohort study was conducted in patients from the JMDC database who were prescribed a study drug (methylphenidate, atomoxetine, or guanfacine) and were in the database for at least 30 days. Among 17 418 patients eligible for the study, nearly all prescriptions were label‐compliant for age; for more than 85% of patients, all prescriptions were label‐compliant for dose, and for approximately 80%, all prescriptions were label‐compliant for contraindicated conditions. We did not find evidence of widespread abuse or noncompliant use of prescribed ADHD medications.![]()

Abstract
IMPORTANCE Reported increases in attention-deficit/hyperactivity disorder (ADHD) diagnoses are accompanied by growing debate about the underlying factors. Although overdiagnosis is often suggested, no comprehensive evaluation of evidence for or against overdiagnosis has ever been undertaken and is urgently needed to enable evidence-based, patient-centered diagnosis and treatment of ADHD in contemporary health services. OBJECTIVE To systematically identify, appraise, and synthesize the evidence on overdiagnosis of ADHD in children and adolescents using a published 5-question framework for detecting overdiagnosis in noncancer conditions. EVIDENCE REVIEW This systematic scoping review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews and Joanna Briggs Methodology, including the PRISMA-ScR Checklist. MEDLINE, Embase, PsychINFO, and the Cochrane Library databases were searched for studies published in English between January 1, 1979, and August 21, 2020. Studies of children and adolescents (aged ≤18 years) with ADHD that focused on overdiagnosis plus studies that could be mapped to 1 or more framework question were included. Two researchers independently reviewed all abstracts and full-text articles, and all included studies were assessed for quality. FINDINGS Of the 12 267 potentially relevant studies retrieved, 334 (2.7%) were included. Of the 334 studies, 61 (18.3%) were secondary and 273 (81.7%) were primary research articles. Substantial evidence of a reservoir of ADHD was found in 104 studies, providing a potential for diagnoses to increase (question 1). Evidence that actual ADHD diagnosis had increased was found in 45 studies (question 2). Twenty-five studies showed that these additional cases may be on the milder end of the ADHD spectrum (question 3), and 83 studies showed that pharmacological treatment of ADHD was increasing (question 4). A total of 151 studies reported on outcomes of diagnosis and pharmacological treatment (question 5). However, only 5 studies evaluated the critical issue of benefits and harms among the additional, milder cases. These studies supported a hypothesis of diminishing returns in which the harms may outweigh the benefits for youths with milder symptoms. CONCLUSIONS AND RELEVANCE This review found evidence of ADHD overdiagnosis and overtreatment in children and adolescents. Evidence gaps remain and future research is needed, in particular research on the long-term benefits and harms of diagnosing and treating ADHD in youths with milder symptoms; therefore, practitioners should be mindful of these knowledge gaps, especially when identifying these individuals and to ensure safe and equitable practice and policy.

Abstract
We aimed to clarify the prescription trend of ADHD drugs in Japanese pediatric outpatients. From January 2012 to December 2018, we evaluated the trends of prescribing methylphenidate-osmotic-controlled release oral delivery system (OROS), atomoxetine, and guanfacine as monotherapy. In boys, methylphenidate-OROS and atomoxetine prescriptions decreased from 46.5 % to 37.2 % and 18.6 % to 15.6 %, respectively. Prescriptions of guanfacine increased from 0.0 % to 12.3 %. In girls, the methylphenidate-OROS prescriptions was not significantly different (37.0 % to 26.4 %); however, atomoxetine decreased from 23.1 % to 16.3 %, and guanfacine increased from 0.0 % to 12.8 %. Methylphenidate-OROS and atomoxetine prescriptions changed to guanfacine between 2012 and 2018.
