Plain English Summary

Background and study aims
Attention deficit hyperactivity disorder (ADHD) is a behavioural disorder that includes symptoms such as inattentiveness, hyperactivity and impulsiveness. ADHD was previously seen as a childhood developmental disorder, which meant that adult mental health services have not been set up to support ADHD patients who become too old for child services. This is the first in-depth study of the transition of ADHD patients from child to adult health services in the UK. It aims to investigate how many young people who have received services for ADHD as a child are in need of services as an adult, what services are available for young adults with ADHD and how people with ADHD, their parents/carers and healthcare professionals experience their transition from child to adult services.

Who can participate?
Paediatricians (doctors specialised in treating children), psychiatrists (mental health doctors) specialising in treating children and young people, young people with ADHD, parents/carers of young people with ADHD and GPs and other healthcare professionals who come into contact with young people with ADHD.

What does the study involve?
There were three parts to the study. In the first part, consultant paediatricians and child and adolescent psychiatrists provided information on the numbers of young people with ADHD who were around the age where they would need to move from child to adult services and where their care moved from and to. The mapping study aimed to create a map of services for young people with ADHD. This involved an online survey to people with ADHD and healthcare professionals, as well as Freedom of Information requests to service providers and commissioners. The third part was to find out people's experiences of moving from child to adults services for ADHD. This involved interviews with people with ADHD, parents/carers and healthcare professionals.

What are the possible benefits and risks of participating?
This study observed and described transition. It did not change the health service provision so it did not affect the services that people would normally have received. Participants gave their time, and there was a possible risk of distress by thinking and talking about difficult experiences or worries about the future. However most participants from all backgrounds had a story that they wished to tell and thought it important to share.

Study information

Scientific title

Children with Attention Deficit Hyperactivity Disorder (ADHD) in transition from children’s services to adult services: a mixed methods project using national surveillance, qualitative and mapping studies

Acronym

CATCh-uS

Study hypothesis

This research focuses on young people diagnosed with ADHD in transition from children’s services to adult services and aims to identify the current perceived need for transfer of young people with ADHD into adult services, to ascertain these services’ utility and to map the current provision.

To address these goals, the study has the following objectives:
1. To identify how many young people with ADHD with an ongoing need for medication need a transfer to adult services and to describe this population across the UK and the Republic of Ireland (ROI)
2. To identify factors influencing service use and to identify factors leading to a transition success/failure
3. To map the services that are currently available for young people with ADHD in transition from childhood to adulthood and summarise what they provide

Intervention

Level of need: Surveillance Study and electronic case note survey
To assess ongoing service needs, we collected surveillance data via the Child and Adolescent Psychiatry Surveillance System (CAPSS) and the British Paediatric Surveillance Unit (BPSU). Over a period of 12 months, consultant paediatricians and child psychiatrists reported ADHD patients who were prescribed ADHD medication, were within 6 months of the upper age boundary of their service and who would require ongoing services for their medication management. Young people with ADHD and comorbid diagnoses, including learning/developmental disabilities, were reported only if it was their ADHD that required ongoing drug treatment. Young people were excluded from the study if they had a diagnosis of ADHD but did not require medication or were unwilling to take it, they required transition to an adult service only for a psychiatric comorbid condition, or they had already been notified to the study.
Those who reported a case were sent a baseline notification survey to collect details of patient treatment and planned transition. After 9 months, a follow-up questionnaire was sent to the reporting clinician to confirm the outcome and details of the transition. To triangulate the data, we also undertook a Clinical Notes Review at one Health Trust which enabled us to compare the total number of cases reported as eligible for transition and the details of transition.

Mapping Study
The mapping study was designed to identify and locate adult health services for patients with ADHD. By making the map available publicly it was also designed to optimise service provision. An online survey distributed via organisational email lists and social media collected data from patients and health professionals. Freedom of information (FOI) requests (based on the same questions as the online survey) were also sent to commissioners and service providers. Responses were displayed and analysed by informant group and location using mapping software. Services were categorised into four groups: dedicated ADHD NHS services, generic NHS services where respondents had experienced care for ADHD, NHS Child Services or Non-NHS services where respondents had received care for ADHD, and ADHD services identified but no respondent reported experience of ADHD care from them.

Utility of services
Semi-structured interviews were conducted with seven stakeholder groups to gather a better understanding of the transition process for ADHD patients. These groups were patients pre-transition, patients post-transition, patients who did not transition but returned to adult services, parents of children with ADHD (some of whom were pre-transition, some post transition and some who did not transition), paediatricians and child psychiatrists, health professionals working in adult mental health services, and GPs. The first four groups were recruited via clinical research nurses, the other groups were recruited from the surveillance and mapping studies, with some GPs also recruited via Twitter or through a snowball method. Data from each stakeholder group were analysed separately using a Framework Analysis approach and then compared to look for consensus and differences in views and experiences of transition.

Results and Publications

Publication and dissemination plan

Throughout this programme of research, we have disseminated our findings via regional, national and international conferences and social media. One of our most impactful outputs is the map of mental health services for adults with ADHD. There were high levels of interest in the map, with over 30,000 views on our website in 12 months and 44,000 impressions on Twitter in 2018. The map was also used by the Exploring Diagnosis research project to send information leaflets to relevant services. UKAAN have agreed to host and keep the map updated and so, as a legacy of the research, it will be available on their website: https://www.ukaan.org/adult-adhd-service-map

As of September 2019, several articles are already published. The NIHR report will be published in 2020 and further papers are in preparation.

IPD sharing statement:
The datasets generated during and/or analysed during the current study will be available upon request from Tamsin Ford at the following email address: catchus@exeter.ac.uk. The qualitative data contain potentially identifiable data despite redactions, and likewise the surveillance data, given the size of the dataset, may also identify individuals. We are happy to share on a named individual basis. The map is now hosted by UK-AAN who will be keeping it updated: https://www.ukaan.org/adult-adhd-service-map-overview .
