Mainstreaming adult ADHD into primary care in the UK: guidance, practice, and best practice recommendations

Support for primary care prescribing for adult ADHD in England: national survey

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, for which there are effective pharmacological treatments that improve symptoms and reduce complications. Guidelines published by the National Institute for Health and Care Excellence recommend that primary care practitioners prescribe medication for adult ADHD under shared-care agreements with Adult Mental Health Services (AMHS). However, provision remains uneven, with some practitioners reporting a lack of support.

AIM

This study aimed to describe elements of support, and their availability/use, in primary care prescribing for adult ADHD medication in England to improve access for this underserved population and inform service improvement.

DESIGN AND SETTING

Cross-sectional surveys were used to elicit data from commissioners, health professionals (HPs), and people with lived experience of ADHD (LE) across England about elements supporting pharmacological treatment of ADHD in primary care.

METHOD

Three interlinked cross-sectional surveys were used to ask every integrated care board in England (commissioners), along with convenience samples of HPs and LEs, about prescribing rates, AMHS availability, wait times, and shared-care agreement protocols/policies for the pharmacological treatment of ADHD in primary care. Descriptive analyses, percentages, and confidence intervals were used to summarise responses by stakeholder group. Variations in reported provision and practice were explored and displayed visually using mapping software.

RESULTS

Data from 782 responders (42 commissioners, 331 HPs, 409 LEs) revealed differences in reported provision by stakeholder group, including for prescribing (95% of HPs versus 64% of LEs). In all, >40% of responders reported extended AMHS wait times of ≥2 years. There was some variability by NHS region - for example, London had the lowest reported extended wait time (25%), while East of England had the highest (55%).

CONCLUSION

Elements supporting appropriate shared-care prescribing of ADHD medication via primary care are not universally available in England. Coordinated approaches are needed to address these gaps.

Practitioner Review: Continuity of mental health care from childhood to adulthood for youths with ADHD - who, how and when?

Many youths with attention-deficit/hyperactivity disorder (ADHD) experience significant long-term impairment and may develop concurrent mental and somatic health difficulties as adults. This is associated with burden and costs for the individual and society which could be prevented through continued support in youth. Yet, only few young people transition to adult mental health services for ongoing care in different countries worldwide. We provide an overview on current transition practices, highlighting the gaps in knowledge and the barriers to effective service transitioning, while considering the large geographical variation in available guidelines and service provision. For ease of use, this review is organized in a question-and-answer format covering different aspects of the transition process and considering both service users' and clinicians' perspectives. Consensus is needed to identify those that require continued care, the optimal timing to arrange transition, and the most suitable services. Finally, we discuss cost-effectiveness of transition practices, consider examples of best practice, and propose recommendations on how to improve transitional care, including the importance of service users' input into transition planning.

Wider health needs in attention deficit hyperactivity disorder from lived and professional experience: a qualitative framework analysis

OBJECTIVES

This study aimed to explore the perspectives of people with attention deficit hyperactivity disorder (ADHD), their supporters and primary care professionals (PCPs), on the wider physical and mental health needs of people with ADHD and the support currently available.

DESIGN

Qualitative semi-structured interviews, analysed using reflexive thematic analysis.

SETTING

Five general practice surgeries across England.

PARTICIPANTS

Participants with lived experience (people with ADHD and their supporters (n=11)) and PCPs (n=9) (eg, general practitioners and practice managers), recruited via clinical academic networks and previous work packages of this study.

RESULTS

We generated three major themes in relation to ADHD, using reflexive thematic analysis: understanding health, barriers to health and addressing health. Within these, participants reflected on mental and physical health challenges, as well as wider social difficulties and variability in support offered/accessed.

CONCLUSIONS

This study highlights that health problems in ADHD are complex and rooted both in individual factors (eg, mental health) and social factors (eg, support). This study also highlights the differences in expectations and fulfilment of healthcare.

The adult ADHD assessment quality assurance standard

Background

Attention Deficit Hyperactivity Disorder (ADHD) frequently persists into adulthood. There are practice guidelines that outline the requirements for the assessment and treatment of adults. Nevertheless, guidelines specifying what constitutes a good quality diagnostic assessment and report and the competencies required to be a specialist assessor are lacking. This can lead to variation in the quality and reliability of adult ADHD assessments. Poor quality assessments may not be accepted as valid indicators of the presence of ADHD by other clinicians or services, resulting in wasteful re-assessments and delays in providing treatment. To address this issue the UK Adult ADHD Network (UKAAN) proposes a quality framework for adult ADHD assessments - the Adult ADHD Assessment Quality Assurance Standard (AQAS).

Methods

The co-authors agreed on five questions or themes that then guided the development of a set of consensus statements. An initial draft was reviewed and amended in an iterative process to reach a final consensus.

Results

What constitutes a high-quality diagnostic assessment and report was agreed by consensus of the co-authors. The resulting guideline emphasises the need to evaluate impairment, describes core competencies required by the assessor and highlights the importance of linking the diagnosis to an appropriate post-diagnostic discussion. Assessments should be completed in the context of a full psychiatric and neurodevelopmental review, and need good interview skills, using a semi-structured interview with open questioning and probing to elicit real life examples of symptoms and impairments. It is recommended that 2 hours or more is required for an adequate assessment including both the diagnostic assessment and initial post-assessment discussions.

Conclusion

The AQAS has been developed as a practical resource to support reliable and valid diagnostic assessments of adult ADHD. It is intended to complement formal training. A secondary objective is to empower patients by providing them with evidence-based information on what to expect from an assessment and assessment report.

[Feasibility of a screening instrument for adult attention-deficit/hyperactivity disorder (ASRS-5) in general practice: A qualitative study]

OBJECTIVES

The aim of the study was to explore the subjective views of general practitioners on the applicability of the Adult ADHD Self-Report Screening Scale for DSM-5 (ASRS-5) as a screening tool for attention-deficit/hyperactivity disorder (ADHD) in adults in general practice.

METHOD

Eleven general practitioners, who had participated in the validation study of the German version of the ASRS-5, were interviewed. For this purpose, a semi-structured interview guide was designed using the Consolidated Framework for Implementation Research (CFIR). The interviews were audio-recorded, transcribed, and analyzed using qualitative content analysis according to Kuckartz.

RESULTS

The ASRS-5 seems to work well in general medical practice. But there is evidence for a lack of knowledge about ADHD in adults among general practitioners and a demand for further training in this area. Moreover, insufficient possibilities for subsequent treatment after a positive ADHD screening were claimed.

DISCUSSION

In general medicine, the introduction of a screening using ASRS-5 in cases of clinical suspicion could be the first step towards improving the management of adult patients with ADHD.

CONCLUSION

Optimizing the management of adults with ADHD requires additional information and training initiatives to support early diagnosis especially in the primary care setting, and to reveal treatment options and care concepts for adults with ADHD.

"I Found Comfort in Exercising": Exploring Experiences With Exercise for Adults With Attention-Deficit/Hyperactivity Disorder

Little is known about how adults with attention-deficit/hyperactivity disorder (ADHD) experience exercise, resulting in a lack of recommendations for supporting this population. We aimed to explore how adults with ADHD experience exercise as a management tool before and after diagnosis and how and why individuals experience issues related to exercise dependence. Fifteen active adults with a diagnosis of ADHD participated in semistructured interviews. Three overarching themes were identified: (a) exercise as a necessity for ADHD, reflecting the need to exercise before a formal ADHD diagnosis, and use of exercise as a management tool postdiagnosis; (b) goals and achievements to live by, reflecting how exercise patterns revolved around a need to make progress toward targets; and (c) activity or exercise: a roller coaster journey, covering the ups and downs of exercise journeys. This article highlights the importance of exercise for adults to manage ADHD and how this can be encouraged and supported.

Patient, supporter and primary healthcare professional perspectives on health risks in over 16s with attention deficit hyperactivity disorder (ADHD) in England: a national survey study

BACKGROUND

Current research suggests that people with attention deficit hyperactivity disorder (ADHD) are at higher risk of physical and mental health disorders. This study aimed to explore these health risks in ADHD from the perspectives of multiple stakeholders.

METHODS

This study forms part of the 'Managing young people with ADHD in Primary care (MAP) study'. A survey developed by the study team was distributed to over 16 year olds with ADHD, their supporters, primary healthcare professionals and health commissioners across England, via social media and through patient/clinical networks (September-October 2022). This survey contained two questions on health risks. Question one asked about views on health risks in ADHD (free text). Question two asked about advice given (options list and free text). Descriptive statistics summarised responses to questions one and two, and qualitative analysis (reflexive thematic analysis) was used to explore free text responses from question one.

RESULTS

782 participants responded to the MAP survey. Of these, 206 healthcare professionals, 157 people with ADHD and 88 supporters answered question one. The most mentioned perceived risks were substance misuse, sleep disorders, weight management and smoking. More people with ADHD reported disordered eating as a health risk (n = 32) than healthcare professionals (n = 5). Generated themes included perceived health risks, impact of living with ADHD, lack of adequate healthcare, and need for ADHD awareness. In respect to advice given (question two), based on responses from 258 professionals, 162 people with ADHD and 100 supporters, the most common advice discussed in consultation was mental health (n = 149, n = 50 and n = 17 respectively). High numbers of respondents reported not giving/receiving advice on wider health (n = 38, n = 88 and n = 61 respectively).

CONCLUSIONS

Findings demonstrate that respondents perceived a range of physical and mental health risks posed by ADHD. These related to difficulties with activities of daily living, as well as healthcare interactions and the impact of core features of ADHD (e.g. impulsivity, emotional dysregulation). These risks are not currently explicitly addressed in United Kingdom national guidance on ADHD. More work is needed to examine and address the broader health outcomes of people with ADHD.

[Pharmacological management of attention-deficit/hyperactivity disorders (ADHD) by generalists and specialists in Germany: a secondary data analysis]

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental health disorders among children, and it is rapidly surging among adults as well. The aim of this study was to investigate the role of community neurologists and psychiatrists as well as general practitioners and paediatricians in prescribing ADHD medications in Germany and whether their role has changed over the 10-year period from 2008 and 2018.

METHODS

In this secondary analysis of anonymized prescribing data, we calculated the absolute and relative frequencies of ADHD prescriptions by neurologists and psychiatrists, summarized as specialists, and family physicians and paediatricians, summarized as generalists, and how it has changed during the years 2008 to 2018.

RESULTS

A total of 620 practices delivered data on 77,504 patients diagnosed with ADHD, 38% (29,396/77,504) of them had received a prescription for ADHD medicine at least once in the study period. Over time, we observed a shift from generalists to specialists. While 59% of patients received their prescription from a generalist and 41% from a specialist in 2008, there was reverse in the ratio in 2018: only 37% received their medication from a generalist and the vast majority (63%) from a specialist. This trend was particularly evident among adults: 58% of them received their ADHD medication from a specialist in 2008, but 80% in 2018. The proportion of children and adolescents who received their prescriptions from a specialist rose from 38% to 51% over the same period.

CONCLUSION

There is a shift in drug prescription away from generalists to specialists, without any discussion of advantages or disadvantages so far. However, this would be desirable, not least because specialists alone may not have sufficient resources to care for all ADHD patients.

Adult ADHD in the Republic of Ireland: the evolving response

Historically, attention-deficit hyperactivity disorder (ADHD) was conceptualised as a disorder of childhood that gradually improved and diminished as individuals transitioned to adulthood. Over the past decade, several studies have been published describing a cohort of adolescents with a childhood diagnosis of ADHD experiencing a continuity of ADHD symptoms into adulthood. Untreated ADHD in adults is associated with personal relationship difficulties, educational and occupational underachievement, comorbid mental health problems, substance misuse, and increased rates of road traffic accidents and criminality. These result in an increased economic burden and broader public health challenges. This review outlines the current framework and stage of development of ADHD services for adults in the Republic of Ireland.

Primary care provision for young people with ADHD: a multi-perspective qualitative study

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is a highly prevalent neurodevelopmental disorder. UK guidance states that primary care has a vital role in effective ADHD management, including referral, medication prescribing and monitoring, and providing broader mental health and wellbeing support. However, many GPs feel unsupported to provide health care for young people with ADHD. Inadequate health care is associated with rising costs for patients and society.

AIM

To investigate the experiences of young people with ADHD accessing primary care in England, from the perspectives of people with lived experience of ADHD and healthcare professionals (HCPs).

DESIGN AND SETTING

A qualitative study. Interviews were conducted with HCPs (GPs, practice managers, and a wellbeing worker) and people with lived experience of ADHD (young people aged 16-25 years and their supporters) located in integrated care systems across England.

METHOD

Semi-structured interviews were conducted with participants at five purposively selected general practices (varying by deprivation, ethnicity, and setting). Questions focused on experiences of accessing/providing health care for ADHD. Reflexive thematic analysis was undertaken within a critical realist framework to understand how provision works in practice and to explore potential improvements.

RESULTS

In total, 20 interviews were completed with 11 HCPs and nine people with lived experience. Three themes were generated: a system under stress, incompatibility between ADHD and the healthcare system, and strategies for change in ADHD primary care provision.

CONCLUSION

Standardisation of ADHD management in primary care, providing better information and support for HCPs, and advising on reasonable adjustments for people with lived experience could help improve access to effective treatments for young people living with ADHD.

UK adult ADHD services in crisis

The UK's services for adult attention-deficit hyperactivity disorder (ADHD) are in crisis, with demand outstripping capacity and waiting times reaching unprecedented lengths. Recognition of and treatments for ADHD have expanded over the past two decades, increasing clinical demand. This issue has been exacerbated by the COVID-19 pandemic. Despite an increase in specialist services, resource allocation has not kept pace, leading to extended waiting times. Underfunding has encouraged growth in independent providers, leading to fragmentation of service provision. Treatment delays carry a human and financial cost, imposing a burden on health, social care and the criminal justice system. A rethink of service procurement and delivery is needed, with multiple solutions on the table, including increasing funding, improving system efficiency, altering the service provision model and clinical prioritisation. However, the success of these solutions hinges on fiscal capacity and workforce issues.

An Objective Assessment of Effect of Stimulants on Attention in Individuals With ADHD

INTRODUCTION

Currently, assessing ADHD treatment response to stimulants relies on rating scales and subjective questionnaires and sometimes a CPT. Such tools fall short of objective, quantifiable measurement of effect, especially in natural settings and can result in inconsistent treatment.

METHOD

We report results from two studies using a novel proof-of-concept approach. A preliminary trial of 10 individuals used a high-fidelity eye tracker; a second study of 100 individuals used webcams at the participants' homes.

RESULTS

Both studies evaluated stimulant effect using reading behavior analysis, being an ADHD symptom that stimulants affect and a major symptom patients want to improve. Both showed a significant change in reading behavior related to medication state, suggesting a clear, objective measure of stimulant effect.

CONCLUSION

Using ubiquitous hardware, investigators created a user-friendly treatment assessment platform where individuals can collect their own objective data within minutes in any setting where they have access to a web camera and computer.

A novel self-rating instrument designed for long-term, app-based monitoring of ADHD symptoms: A mixed-methods development and validation study

Background

Regular outcome monitoring is essential for effective attention deficit hyperactivity disorder (ADHD) treatment, yet routine care often limits long-term contacts to annual visits. Smartphone apps can complement current practice by offering low-threshold, long-term sustainable monitoring capabilities. However, special considerations apply for such measurement which should be anchored in stakeholder preferences.

Methods

This mixed-methods study engaged 13 experienced clinicians from Region Stockholm in iterative qualitative interviews to inform development of an instrument for app-based ADHD monitoring: the mHealth scale for Continuous ADHD Symptom Self-monitoring (mCASS). A subsequent survey, including the mCASS and addressing app-based monitoring preferences, was administered to 397 individuals with self-reported ADHD. Psychometric properties of the mCASS were explored through exploratory factor analysis and examinations of internal consistency. Concurrent validity was calculated between the mCASS and the Adult ADHD Self-Report Scale-V1.1 (ASRS-V1.1). Additional quantitative analyses included summary statistics and repeated-measures ANOVAs.

Results

Clinicians identified properties influencing willingness to use and adherence including content validity, clinical relevance, respondent burden, tone, wording and preferences for in-app results presentation. The final 12-item mCASS version demonstrated four factors covering everyday tasks, productivity, rest and recovery and interactions with others, explaining 47.4% of variance. Preliminary psychometric assessment indicated satisfactory concurrent validity (r = .595) and internal consistency (α = .826).

Conclusions

The mCASS, informed by clinician and patient experiences, appears to be valid for app-based assessment of ADHD symptoms. Furthermore, insights are presented regarding important considerations when developing mobile health (mHealth) instruments for ADHD individuals. These can be of value for future, similar endeavours.

Training and specialisation of psychiatrists in ADHD

OBJECTIVE

To identify the level of training of Australian psychiatrists in Attention Deficit Hyperactivity Disorder (ADHD), and to compare the number of psychiatrists specialising in ADHD versus other psychiatric conditions on the basis of the prevalence of conditions, by interrogating the RANZCP 'Find a Psychiatrist' database.

CONCLUSION

Fewer psychiatrists listed in the RANZCP database specialise in ADHD than in many other psychiatric conditions. Given that 5% of the Australian population suffers from ADHD, the condition can have significant adverse outcomes and is a common comorbidity with other psychiatric conditions, the RANZCP Training Program would be improved by requiring an in-depth knowledge of ADHD. Further training in ADHD would assist many practising psychiatrists.

Protocol for the mixed methods, Managing young people (aged 16-25) with Attention deficit hyperactivity disorder in Primary care (MAP) study: mapping current practice and co-producing guidance to improve healthcare in an underserved population

INTRODUCTION

Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder in children and adolescents, with an average worldwide prevalence of 5%. Up to 40% of young people continue to experience symptoms into adulthood. Young people with ADHD experience poorer outcomes than their peers across multiple domains, with treatment shown to reduce these risks. Primary care practitioners play an important role in healthcare provision for this group in the UK. However, many feel unsure about how best to provide support, reporting prescribing concerns and need for more evidence-based guidance. A lack of national data on primary care provision hinders efforts to improve access to care and optimise outcomes. This mixed-methods study aims to provide evidence that may be used to improve primary care services for young people aged 16-25 years with ADHD.

METHODS AND ANALYSIS

There are three interlinked work packages: (a) a mapping study including a survey of stakeholders (healthcare professionals, people with ADHD and commissioners) will map ADHD prescribing practice, shared-care arrangements, available support and practitioner roles by geographic locations across England for different respondent groups; (b) a qualitative study involving semi-structured interviews with stakeholders (10-15 healthcare professionals and 10-15 people with ADHD) will explore experiences of 'what works' and 'what is needed' in terms of service provision and synthesise findings; (c) workshops will integrate findings from (a) and (b) and work with stakeholders to use this evidence to codevelop key messages and guidance to improve care.

ETHICS AND DISSEMINATION

The protocol has been approved by Yorkshire and the Humber-Bradford Leeds Research Ethics Committee. Recruitment commenced in September 2022. Findings will be disseminated via research articles in peer-reviewed journals, conference presentations, public involvement events, patient groups and media releases. A summary of study findings will be shared with participants at the end of the study.

Autism in England: assessing underdiagnosis in a population-based cohort study of prospectively collected primary care data

Background

Autism has long been viewed as a paediatric condition, meaning that many autistic adults missed out on a diagnosis as children when autism was little known. We estimated numbers of diagnosed and undiagnosed autistic people in England, and examined how diagnostic rates differed by socio-demographic factors.

Methods

This population-based cohort study of prospectively collected primary care data from IQVIA Medical Research Data (IMRD) compared the prevalence of diagnosed autism to community prevalence to estimate underdiagnosis. 602,433 individuals registered at an English primary care practice in 2018 and 5,586,100 individuals registered between 2000 and 2018 were included.

Findings

Rates of diagnosed autism in children/young people were much higher than in adults/older adults. As of 2018, 2.94% of 10- to 14-year-olds had a diagnosis (1 in 34), vs. 0.02% aged 70+ (1 in 6000). Exploratory projections based on these data suggest that, as of 2018, 463,500 people (0.82% of the English population) may have been diagnosed autistic, and between 435,700 and 1,197,300 may be autistic and undiagnosed (59-72% of autistic people, 0.77%-2.12% of the English population). Age-related inequalities were also evident in new diagnoses (incidence): c.1 in 250 5- to 9-year-olds had a newly-recorded autism diagnosis in 2018, vs. c.1 in 4000 20- to 49-year-olds, and c.1 in 18,000 people aged 50+.

Interpretation

Substantial age-related differences in the proportions of people diagnosed suggest an urgent need to improve access to adult autism diagnostic services.
