Management of ADHD in children and adolescents: clinical audit in a South African setting

Adherence to Clinical Guidelines for Dose Finding and Monitoring Methylphenidate Use: A Medical Record Audit in Child and Adolescent Mental Health Care and Pediatric Settings

Background: Guideline adherence is important to ensure optimal and safe use of methylphenidate for children and adolescents with attention-deficit/hyperactivity disorder (ADHD). We investigated adherence to Dutch guidelines regarding dosing and monitoring of methylphenidate in child and adolescent mental health care and pediatric treatment settings. Methods: Five hundred six medical records of children and adolescents were investigated in 2015 and 2016. We assessed adherence to the following guideline recommendations: (1) at least four visits during the dose-finding phase; (2) monitoring thereafter at least every 6 months; (3) measuring height and weight at least annually; and (4) the use of validated questionnaires to assess treatment response. Pearson's chi-squared test statistics were used to examine differences between settings. Results: Only a small portion of patients had at least four visits during the dose-finding phase (5.1% in the first 4 weeks to 12.4% in the first 6 weeks). Also, less than half of the patients (48.4%) were seen at least every 6 months. Height was recorded at least annually in 42.0% of patients, weight in 44.9%, and both recorded in a growth chart in 19.5%. Questionnaires to assess treatment response were only used in 2.3% of all visits. When comparing both settings, more patients in the pediatric settings were seen every 6 months, although height and weight were recorded more often in the mental health care setting. Conclusion: Overall, guideline adherence was low. Training of clinicians and adding guideline recommendations to electronic medical records templates may improve adherence. Additionally, we should aim to close the gap between guidelines and clinical practice by looking critically at the feasibility of guidelines.

Clinicians' Adherence to Guidelines When Initiating Methylphenidate Treatment

Aims: Between 2008 and 2012, the number of children and adolescents in the Netherlands who received methylphenidate prescriptions increased by 35.6%. We determined guideline adherence regarding the assessment of attention-deficit/hyperactivity disorder (ADHD) and rates of off-label use in those 2 years. We also compared adherence to guidelines between mental health and pediatrics settings. Methods: We conducted a medical file audit of 506 children or adolescents who had received a first methylphenidate prescription in 2008 (n = 208) or 2012 (n = 298) across mental health (n = 333) and pediatrics outpatient clinics (n = 173) in the Netherlands and assessed adherence to seven guideline recommendations. Results: We did not find significant differences between 2008 and 2012 regarding the mean adherence to the seven recommendations (43% vs. 45%) or the percentage of off-label use (35% vs. 30%). Best adherence rates (over the years 2008 and 2012 combined) concerned the assessment of comorbidities (89%) and the involvement of teachers in the diagnostic process (75%). Least frequently adhered to were assessing ADHD severity (1%), the use of a (semi-)structured parent interview (16%), and providing psycho-education to parents (42%) or teachers (1%). Mental health settings showed better adherence than pediatrics settings (over the years 2008 and 2012 combined) concerning the use of (semi-)structured parent interviews (22% vs. 3.1%), having a separate diagnostic session directed at the child (81% vs. 63%), assessment of comorbidities (95% vs. 76%), and providing psycho-education to parents (51% vs. 24%). Conclusions: There was neither a decrease in adherence to guidelines nor an increase in off-label use between 2008 and 2012. However, there is ample room for improvement regarding guideline adherence.

Treatments for child and adolescent attention deficit hyperactivity disorder in low and middle-income countries: A narrative review

BACKGROUND

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects approximately 2-7 % of children globally and is associated with a myriad of difficulties that have long-term consequences. Most children and adolescents live in low- and middle-income countries (LMICs), but there are few reports and no consolidation of findings on ADHD treatment outcomes in this population. We conducted a review of ADHD treatment literature for children and adolescents living in LMICs.

METHODS

Studies were identified using databases (PsychoINFO, Pubmed, MEDLINER, EMBASE, Global Health, Academic Search Complete, Google Scholar). The initial search produced 139 articles. These were filtered for language, title, abstract, and full-text keyword identification to yield a final 20 articles to be included in this review.

RESULTS

Reports on outcomes of both psychological and pharmacological treatment were relatively sparse, particularly the former, which mostly referred to parent training and multimodal programs in pre-school children. Most evidence exists for the benefit of methylphenidate-IR with a few reports on other agents, including clonidine, atomoxetine, and lisdexamfetamine. Methylphenidate is the most common agent to treat ADHD in youth in LMICs. Younger age, combined subtype, and comorbid oppositional defiant disorder were associated with poorer treatment outcome.

CONCLUSION

Access to treatment for ADHD is overall limited in LMICs and varied among individual countries. Pharmacological treatments were generally more available than psychological interventions. Several barriers including stigma, cost, and lack of resources were reported to impact treatment acceptance. More research in LMICs is needed to improve and expand mental health services in these regions.

A situational analysis of child and adolescent mental health services and systems in the Western Cape Province of South Africa

BACKGROUND

Even though child and adolescent mental health is a global health priority, services are very limited, particularly in low- and middle-income countries (LMIC), and therefore need comprehensive strengthening. This requires knowledge of the hardware elements of the system (human resources, financing, medicines, technology, organisational structure, service infrastructure, and information systems). This study sought to examine these elements of child and adolescent mental health (CAMH) services and systems in the Western Cape Province of South Africa.

METHODS

The World Health Organization Assessment Instrument of Mental Health Systems (WHO-AIMS) version 2.2 of 2005 was adapted to identify key variables of interest in CAMH. Data were collected for the calendar year 2016 and focused on the public health sector. We outlined findings based on best available data across the six domains of the WHO-AIMS.

RESULTS

In domain 1, we found no provincial CAMH policy or implementation plans to support the national CAMH policy and were unable to identify a CAMH-specific budget. In domain 2, there was no dedicated provincial leadership structure for CAMH, and no dedicated or 'child- and adolescent-friendly' mental health services at primary or secondary care levels. At tertiary level, there were only three specialist CAMH teams. The majority of CAMH resources were based in the City of Cape Town, with limited resources in the rural districts. Essential medicines were available in all facilities, and the majority of children and adolescents had access to free services. In domain 3, data were limited about the extent of training offered to primary healthcare staff, and little or no psychosocial interventions were available in primary care. Domain 4 identified a small and variable CAMH workforce across all levels of care. In domain 5, few public health campaigns focused on CAMH, and little evidence of formal intersectoral collaboration on CAMH was identified. Domain 6 identified significant limitations in health information systems for CAMH, including lack of child- and adolescent-specific and disaggregated data to establish baselines for policy development, monitoring, evaluation and CAMH research.

CONCLUSIONS

This study identified significant structural weaknesses in CAMH and presents a clear call for action to strengthen services and systems in the province and in South Africa. it would be important to expand research also to include provider and user perspectives for service strengthening.

Vocal Characteristics of School-Aged Children With and Without Attention Deficit Hyperactivity Disorder

OBJECTIVES

The aim of this study was to describe the laryngeal anatomy, perceptual, acoustic, and aerodynamic vocal characteristics of school-aged children with and without Attention Deficit Hyperactivity Disorder (ADHD). The predisposition that children with ADHD have for laryngeal injuries are recurrent in nature and are more often than not overlooked as laryngitis. Previous studies have reported varied results on the prevalence rates of pediatric vocal fold nodules within the school-aged ADHD population.

STUDY DESIGN

A static, two-group comparison was used in the study to investigate the clinical, perceptual, acoustic, and aerodynamic vocal characteristics of children between 7 and 9 years old with and without ADHD.

METHODS

The study replicated the protocol as executed by Barona-Lleo and Fernandez (2016) with additions. The Multidimensional Voice Program and the Voice Range Profile as additions to the assessment of vocal parameters were used with which comparable dysphonia severity index scores were calculated. Once-off clinical, perceptual, acoustic, and aerodynamic voice assessments were conducted on 20 age-gender matched participants (Control group mean age [months] = 98.80, standard deviation = 10.379; ADHD group mean age [months] = 108.00, standard deviation = 10.873). It was hypothesized that children with ADHD would have more hyperfunctional vocal characteristics; leading to laryngeal injuries, than their control group peers.

RESULTS

Forty-five percent (n = 9) of the total sample population (both groups combined) had laryngeal pathology. Similar parent reported etiological voice symptoms and vocal habits were seen across both groups. Both groups performed similarly across both perceptual and aerodynamic voice assessments. Acoustically, the control group achieved significantly higher producible pitches than the ADHD group (P = 0.028) and were found to have more dysphonic dysphonia severity index scores than their ADHD group peers (P = 0.034).

CONCLUSION

Prepubertal, school-aged children with or without ADHD may have similar vocal characteristics than previously thought. This is in support of the null hypothesis. The authors of the current study recommend that vocal screening in all school-aged children be carried out as an effective measure to monitor voice disorders in the pediatric population. Future research into larger sample sizes with this population with a special focus on the effect that central nervous system stimulants may have on the voice is recommended.
