Transition between child and adult services for young people with attention-deficit hyperactivity disorder (ADHD): findings from a British national surveillance study.

BACKGROUND: Optimal transition from child to adult services involves continuity, joint care, planning meetings and information transfer; commissioners and service providers therefore need data on how many people require that service. Although attention-deficit hyperactivity disorder (ADHD) frequently persists into adulthood, evidence is limited on these transitions. AIMS: To estimate the national incidence of young people taking medication for ADHD that require and complete transition, and to describe the proportion that experienced optimal transition. METHOD: Surveillance over 12 months using the British Paediatric Surveillance Unit and Child and Adolescent Psychiatry Surveillance System, including baseline notification and follow-up questionnaires. RESULTS: Questionnaire response was 79% at baseline and 82% at follow-up. For those aged 17-19, incident rate (range adjusted for non-response) of transition need was 202-511 per 100 000 people aged 17-19 per year, with successful transition of 38-96 per 100 000 people aged 17-19 per year. Eligible young people with ADHD were mostly male (77%) with a comorbid condition (62%). Half were referred to specialist adult ADHD and 25% to general adult mental health services; 64% had referral accepted but only 22% attended a first appointment. Only 6% met optimal transition criteria. CONCLUSIONS: As inclusion criteria required participants to be on medication, these estimates represent the lower limit of the transition need. Two critical points were apparent: referral acceptance and first appointment attendance. The low rate of successful transition and limited guideline adherence indicates significant need for commissioners and service providers to improve service transition experiences.

Transition as a topic in psychiatry training throughout Europe: trainees' perspectives.

The majority of adolescents with mental health problems do not experience continuity of care when they reach the transition boundary of their child and adolescent mental health service. One of the obstacles for a smooth transition to adult mental health services concerns the lack of training for health-care professionals involved in the transition process. This study aims to seek psychiatric trainees' opinions regarding training on transition and the knowledge and skills required for managing transition. A survey was distributed to trainees residing in European countries. Trainees from 36 countries completed the questionnaire, of which 63% reported that they came into contact with youth and young adults (16-26 years) during their clinical practice. Twenty-seven percent of trainees stated they have good to very good knowledge about the transition process. Theoretical training about transition was reported in only 17% of the countries, and practical training in 28% of the countries. Ninety-four percent of trainees indicated that further training about transition is necessary. The content of subsequent transition-related training can be guided by the findings of the MILESTONE project.

Clinician perspectives on the use of National Institute for Health and Care Excellence guidelines for the process of transition in Attention Deficit Hyperactivity Disorder.

BACKGROUND: The UK National Institute for Health and Care Excellence (NICE) clinical guidelines recommends the following steps in the transition from child to adult services for young people with attention deficit hyperactivity disorder (ADHD): reassessment before and after transition, transition planning, formal meeting between services, and involvement from young person and carer, completed by age 18. METHODS: A UK surveillance study asked clinicians to report young people on their caseloads with ADHD in need of transition to adult services in 2016 to support their continued access to medication need. Clinicians reported young people as they aged to within 6 months of the transition boundary, a prospective questionnaire prior to transition asked about intended transition and the use of local transition protocols. A retrospective questionnaire sent 9 months later established which steps recommended by NICE were followed during transition. Clinicians (38) working in child or adult services were interviewed about their experiences of transition and the use of NICE guidelines during transition and were analysed using a framework approach. RESULTS: Information was shared between services in 85% of the 315 identified transition cases. A joint meeting was planned in 16% of cases; joint working before transfer occurred in 10% of cases. Clinicians were aware of NICE guidelines; they had mixed views on whether (local) guidelines or protocols were helpful. The main reason for not following guidelines was workload and resources: "NICE recommends stuff that is miles above what we will ever be able to provide". CONCLUSIONS: Clinicians involved in the transition process of young people with ADHD judged NICE guidelines to be unrealistic given the current limited resources and service organization. More open dialogue is needed for recommendations on service models to bridge the gap between guideline recommendations and what is viewed as feasible and how implementation of guidance is funded, monitored, and prioritized. This may lead to valuable changes in the consultation process, for example, consideration of a layered (gold, standard, and minimal) system for some NICE guidelines.

A cross-cultural qualitative study of the ethical aspects in the transition from child mental health services to adult mental health services.

BACKGROUND: Transitioning from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) raises novel ethical aspects for healthcare professionals, as well as for young people, their parents and carers. METHOD: Focus groups were conducted in Croatia, Ireland and the United Kingdom with youth mental health groups and youth representatives with no mental health (MH) remit. One hundred and eleven participants, aged from 16 to 60 years, contributed to discussions. RESULTS: Perpetuation of stigma, autonomy and decision-making were central themes as both enablers and deterrents of successful transition. The tension between professional (and at times parental) paternalism and young persons' growing autonomy was well captured in the themes; (a) desired practice, (b) who should decide, (c) the process of decision-making and (d) potential harm(s). CONCLUSIONS: This study provides insight into the ethical values, particularly autonomy and collaboratively working, which people expect to underpin the transition between CAMHS and AMHS. KEY PRACTITIONER MESSAGE: Engaging young people early in making decisions about their future care can enhance trust between practitioner and the young person. In addition to diagnosis, a number of factors (such as moving home; waiting lists and stigma) may need to be taken into account when considering the direction of future health care. When possible, alternatives to AMHS should be considered if considered by the young person to be a less-stigmatising treatment option.

In transition with ADHD: the role of information, in facilitating or impeding young people's transition into adult services.

BACKGROUND: Many national and regional clinical guidelines emphasise the need for good communication of information to young people and their parent/carers about what to expect during transition into adult services. Recent research indicates only a minority of young people in need of transition for Attention Deficit Hyperactivity Disorder (ADHD) experience continuity of care into adulthood, with additional concerns about quality of transition. This qualitative study explored the role that information plays in experiences of transition from the perspectives of parent/carers and young people. METHODS: Participants were recruited from 10 National Health Service Trusts, located across England, with varying service configurations. Ninety two qualitative interviews were conducted: 64 with young people with ADHD at different stages relative to transition, and 28 with parent/carers. Thematic analysis of data was completed using the Framework Method. RESULTS: Interviewees reported a range of experiences; however reliance on parent/carers to gather and translate key information, and negative experiences associated with poor communication of information, were universal. Three themes emerged: Navigating information with help from parents; Information on ADHD into adulthood; Information about the transition process. The first revealed the essential role of parent in the translation and application of information, the other two explored distinct types of information necessary for a smooth transition. Interviewees made recommendations for clinical practice similar to UK (United Kingdom) National Institute for Health and Care Excellence (NICE) guidelines, with an additional emphasis on providing nuanced information on ADHD as a potentially long term condition. It was important to interviewees that General Practitioners had a basic understanding of adult ADHD and also had access to information about service provision. CONCLUSIONS: Our findings illustrate that the availability and communication of information to young people and their parent/carers is an essential component of the transition process between child and adult ADHD services. How and when it is provided may support or impede transition. This study constitutes a substantial contribution to the evidence base, drawing on interviews from a range of participants across England and from Trusts offering different types of services.

Improving mental health pathways and care for adolescents in transition to adult services (IMPACT): a retrospective case note review of social and clinical determinants of transition.

BACKGROUND: Poor transitions to adult care from child and adolescent mental health services may increase the risk of disengagement and long-term negative outcomes. However, studies of transitions in mental health care are commonly difficult to administer and little is known about the determinants of successful transition. The persistence of health inequalities related to access, care, and outcome is now well accepted including the inverse care law which suggests that those most in need of services may be the least likely to obtain them. We sought to examine the pathways and determinants of transition, including the role of social class. METHOD: A retrospective systematic examination of electronic records and case notes of young people eligible to transition to adult care over a 4-year period across five Health and Social Care NHS Trusts in Northern Ireland. RESULTS: We identified 373 service users eligible for transition. While a high proportion of eligible patients made the transition to adult services, very few received an optimal transition process and many dropped out of services or subsequently disengaged. Clinical factors, rather than social class, appear to be more influential in the transition pathway. However, those not in employment, education or training (NEET) were more likely (OR 3.04: 95% CI 1.34, 6.91) to have been referred to Adult Mental Health Services (AMHS), as were those with a risk assessment or diagnosis (OR 4.89: 2.45, 9.80 and OR 3.36: 1.78, 6.34), respectively. CONCLUSIONS: Despite the importance of a smoother transition to adult services, surprisingly, few patients experience this. There is a need for stronger standardised policies and guidelines to ensure optimal transitional care to AMHS. The barriers between different arms of psychiatry appear to persist. Joint working and shared arrangements between child and adolescent and adult mental health services should be fostered.

Training of adult psychiatrists and child and adolescent psychiatrists in europe: a systematic review of training characteristics and transition from child/adolescent to adult mental health services.

BACKGROUND: Profound clinical, conceptual and ideological differences between child and adult mental health service models contribute to transition-related discontinuity of care. Many of these may be related to psychiatry training. METHODS: A systematic review on General Adult Psychiatry (GAP) and Child and Adult Psychiatry (CAP) training in Europe, with a particular focus on transition as a theme in GAP and CAP training. RESULTS: Thirty-four full-papers, six abstracts and seven additional full text documents were identified. Important variations between countries were found across several domains including assessment of trainees, clinical and educational supervision, psychotherapy training and continuing medical education. Three models of training were identified: i) a generalist common training programme; ii) totally separate training programmes; iii) mixed types. Only two national training programs (UK and Ireland) were identified to have addressed transition as a topic, both involving CAP exclusively. CONCLUSION: Three models of training in GAP and CAP across Europe are identified, suggesting that the harmonization is not yet realised and a possible barrier to improving transitional care. Training in transition has only recently been considered. It is timely, topical and important to develop evidence-based training approaches on transitional care across Europe into both CAP and GAP training.

A systematic review of the literature on ethical aspects of transitional care between child- and adult-orientated health services.

BACKGROUND: Healthcare policy and academic literature have promoted improving the transitional care of young people leaving child and adolescent mental health services (CAMHS). Despite the availability of guidance on good practice, there seems to be no readily accessible, coherent ethical analysis of transition. The ethical principles of non-maleficence, beneficence, justice and respect for autonomy can be used to justify the need for further enquiry into the ethical pros and cons of this drive to improve transitional care. The objective of this systematic review was therefore to systematically search for existing ethical literature on child- to adult-orientated health service transitions and to critically appraise and collate the literature, whether empirical or normative. METHODS: A wide range of bioethics, biomedical and legal databases, grey literature and bioethics journals were searched. Ancestral and forward searches of identified papers were undertaken. Key words related to transition, adolescence and young adulthood, ethics, law and health. The timeframe was January 2000 to at least March 2016. Titles, abstracts and, where necessary, full articles were screened and duplicates removed. All included articles were critically appraised and a narrative synthesis produced. RESULTS: Eighty two thousand four hundred eighty one titles were screened, from which 96 abstracts were checked. Forty seven full documents were scrutinised, leading to inclusion of two papers. Ancestral and forward searches yielded four further articles. In total, one commentary, three qualitative empirical studies and two clinical ethics papers were found. All focused on young people with complex care needs and disabilities. The three empirical papers had methodological flaws. The two ethical papers were written from a clinical ethics context rather than using a bioethical format. No literature identified specifically addressed the ethical challenges of balancing the delivery of transitional care to those who need it and the risk of pathologizing transient and self-limited distress and dysfunction, which may be normal during adolescence. CONCLUSIONS: There is very little research on ethical aspects of transitional care. Most existing studies come from services for young people with complex care needs and disabilities. There is much scope for improvement in the amount and quality of empirical research and ethical analysis in this area.

The interface between child/adolescent and adult mental health services: results from a European 28-country survey.

Transition-related discontinuity of care is a major socioeconomic and societal challenge for the EU. The current service configuration, with distinct Child and Adolescent Mental Health (CAMHS) and Adult Mental Health Services (AMHS), is considered a weak link where the care pathway needs to be most robust. Our aim was to delineate transitional policies and care across Europe and to highlight current gaps in care provision at the service interface. An online mapping survey was conducted across all 28 European Countries using a bespoke instrument: The Standardized Assessment Tool for Mental Health Transition (SATMEHT). The survey was directed at expert(s) in each of the 28 EU countries. The response rate was 100%. Country experts commonly (12/28) reported that between 25 and 49% of CAMHS service users will need transitioning to AMHS. Estimates of the percentage of AMHS users aged under 30 years who had has previous contact with CAMHS were most commonly in the region 20-30% (33% on average).Written policies for managing the interface were available in only four countries and half (14/28) indicated that no transition support services were available. This is the first survey of CAMHS transitional policies and care carried out at a European level. Policymaking on transitional care clearly needs special attention and further elaboration. The Milestone Study on transition should provide much needed data on transition processes and outcomes that could form the basis for improving policy and practice in transitional care.

A prospective, quantitative study of mental health act assessments in England following the 2007 amendments to the 1983 act: did the changes fulfill their promise?

BACKGROUND: In 2008, the Mental Health Act (MHA) 2007 amendments to the MHA 1983 were implemented in England and Wales. The amendments were intended to remove perceived obstacles to the detention of high risk patients with personality disorders (PDs), sexual deviance and learning disabilities (LDs). The AMEND study aimed to test the hypothesis that the implementation of these changes would lead to an increase in numbers or proportions of patients with these conditions who would be assessed and detained under the MHA 2007. METHOD: A prospective, quantitative study of MHA assessments undertaken between July-October 2008-11 at three English sites. Data were collected from local forms used for MHA assessment documentation and patient electronic databases. RESULTS: The total number of assessments in each four month period of data collection varied: 1034 in 2008, 1042 in 2009, 1242 in 2010 and 1010 in 2011 (n = 4415). Of the assessments 65.6% resulted in detention in 2008, 71.3% in 2009, 64.7% in 2010 and 63.5% in 2011. There was no significant change in the odds ratio of detention when comparing the 2008 assessments against the combined 2009, 2010 and 2011 data (OR = 1.025, Fisher's exact Χ 2 p = 0.735). Only patients with LD and 'any other disorder or disability of the mind' were significantly more likely to be assessed under the MHA post implementation (Χ2 = 5.485, P = 0.018; Χ2 = 24.962, P > 0.001 respectively). There was no significant change post implementation in terms of the diagnostic category of detained patients. CONCLUSIONS: In the first three years post implementation, the 2007 Act did not facilitate the compulsory care of patients with PDs, sexual deviance and LDs.

Transitioning care-leavers with mental health needs: 'they set you up to fail!'

BACKGROUND: Children in the UK care system often face multiple disadvantages in terms of health, education and future employment. This is especially true of mental health where they present with greater mental health needs than other children. Although transition from care - the process of leaving the local authority as a child-in-care to independence - is a key juncture for young people, it is often experienced negatively with inconsistency in care and exacerbation of existing mental illness. Those receiving support from child and adolescent mental health services (CAMHS), often experience an additional, concurrent transfer to adult services (AMHS), which are guided by different service models which can create a care gap between services. METHOD: This qualitative study explored care-leavers' experiences of mental illness, and transition in social care and mental health services. Twelve care-leavers with mental health needs were interviewed and data analysed using framework analysis. RESULTS: Sixteen individual themes were grouped into four superordinate themes: overarching attitudes towards the care journey, experience of social care, experience of mental health services and recommendations. CONCLUSIONS: Existing social care and mental health teams can improve the care of care-leavers navigating multiple personal, practical and service transitions. Recommendations include effective Pathway Planning, multiagency coordination, and stating who is responsible for mental health care and its coordination. Participants asked that youth mental health services span the social care transition; and provide continuity of mental health provision when care-leavers are at risk of feeling abandoned and isolated, suffering deteriorating mental health and struggling to establish new relationships with professionals. Young people say that the key to successful transition and achieving independence is maintaining trust and support from services.

Recommendations for the transition of patients with ADHD from child to adult healthcare services: a consensus statement from the UK adult ADHD network.

The aim of this consensus statement was to discuss transition of patients with ADHD from child to adult healthcare services, and formulate recommendations to facilitate successful transition. An expert workshop was convened in June 2012 by the UK Adult ADHD Network (UKAAN), attended by a multidisciplinary team of mental health professionals, allied professionals and patients. It was concluded that transitions must be planned through joint meetings involving referring/receiving services, patients and their families. Negotiation may be required to balance parental desire for continued involvement in their child's care, and the child's growing autonomy. Clear transition protocols can maintain standards of care, detailing relevant timeframes, responsibilities of agencies and preparing contingencies. Transition should be viewed as a process not an event, and should normally occur by the age of 18, however flexibility is required to accommodate individual needs. Transition is often poorly experienced, and adherence to clear recommendations is necessary to ensure effective transition and prevent drop-out from services.

Aggression in children with behavioural/emotional difficulties: seeing aggression on television and video games.

BACKGROUND: Mental health professionals are often asked to give advice about managing children's aggression. Good quality evidence on contributory environmental factors such as seeing aggression on television and in video games is relatively lacking, although societal and professional concerns are high. This study investigated possible associations between seeing aggression in such media and the aggressive behaviour of children attending specialist outpatient child and adolescent mental health services (CAMHS). METHODS: In this mixed methods study, forty-seven British children aged 7-11 years with behavioural/emotional difficulties attending CAMHS and their carers participated in a survey; twenty purposively-selected children and a parent/carer of theirs participated in a qualitative study, involving semi-structured interviews, analysed using the Framework Analysis Approach; findings were integrated. RESULTS: Children attending CAMHS exhibit clinically significant aggression, of varying types and frequency. They see aggression in multiple real and virtual settings. Verbal aggression was often seen, frequently exhibited and strongly associated with poor peer relationships and low prosocial behaviour. Children did not think seeing aggression influences their own behaviour but believed it influences others. Carers regarded aggression as resulting from a combination of inner and environmental factors and seeing aggression in real-life as having more impact than television/video games. CONCLUSIONS: There is yet no definitive evidence for or against a direct relationship between aggression seen in the media and aggression in children with behavioural/emotional difficulties. Future research should take an ecological perspective, investigating individual, developmental and environmental factors. Carers, professional organisations and policy makers should address aggression seen in all relevant area of children's lives, primarily real-life and secondly virtual environments.

Adaptation and validation of the On Your Own Feet - Transition Experiences Scale evaluating transitions to adult services among adolescent mental health service users in Europe.

PURPOSE: Experiences of young people transitioning from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) have mostly been investigated qualitatively. This study adapts and validates the On Your Own Feet - Transition Experiences Scale (OYOF-TES) in a sample of CAMHS users in Europe and describes young people's and parents' experiences with transition and end of care at CAMHS. METHODS: The OYOF-TES was adapted to a mental health setting and translated. An End Of Care (OYOF-EOC) version (self- and parent-report) was developed. A total of 457 young people and 383 parents completed an OYOF-TES or OYOF-EOC. Psychometric properties and descriptives are presented. RESULTS: The Cronbach's alphas of the OYOF-TES and OYOF-EOC parent/self-report ranged from 0.92 to 0.94. The two-factor structure was confirmed. The mean overall satisfaction reported by young people was 6.15 (0-10; SD=2.92) for transition and 7.14 (0-10; SD=2.37) for care ending. However, 26.7%-36.4% of young people were unsatisfied. DISCUSSION: The OYOF-TES and OYOF-EOC can be used reliably in mental healthcare settings to capture young people's and parents' transition experiences. The majority of young people and parents was satisfied with the process of transition and care ending, yet a third of young people had negative experiences.

The Association Between Trajectories of Self-reported Psychotic Experiences and Continuity of Mental Health Care in a Longitudinal Cohort of Adolescents and Young Adults.

BACKGROUND AND HYPOTHESIS: Young people (YP) with psychotic experiences (PE) have an increased risk of developing a psychiatric disorder. Therefore, knowledge on continuity of care from child and adolescent (CAMHS) to adult mental health services (AMHS) in relation to PE is important. Here, we investigated whether the self-reported trajectories of persistent PE were associated with likelihood of transition to AMHS and mental health outcomes. STUDY DESIGN: In this prospective cohort study, interviews and questionnaires were used to assess PE, mental health, and service use in 763 child and adolescent mental health service users reaching their service's upper age limit in 8 European countries. Trajectories of self-reported PE (3 items) from baseline to 24-month follow-up were determined using growth mixture modeling (GMM). Associations were assessed with auxiliary variables and using mixed models. Study results. At baseline, 56.7% of YP reported PE. GMM identified 5 trajectories over 24 months: medium increasing (5.2%), medium stable (11.7%), medium decreasing (6.5%), high decreasing (4.2%), and low stable (72.4%). PE trajectories were not associated with continuity of specialist care or transition to AMHS. Overall, YP with PE reported more mental health problems at baseline. Persistence of PE or an increase was associated with poorer outcomes at follow-up. CONCLUSIONS: PE are common among CAMHS users when reaching the upper age limit of CAMHS. Persistence or an increase of PE was associated with poorer mental health outcomes, poorer prognosis, and impaired functioning, but were less discriminative for continuity of care.

'Talking a different language': an exploration of the influence of organizational cultures and working practices on transition from child to adult mental health services.

BACKGROUND: Organizational culture is manifest in patterns of behaviour underpinned by beliefs, values, attitudes and assumptions, which can influence working practices. Cultural factors and working practices have been suggested to influence the transition of young people moving from child to adult mental health services. Failure to manage and integrate transitional care effectively can lead to young people losing contact with health and social care systems, resulting in adverse effects on health, well-being and potential. METHODS: The study aim was to identify the organisational factors which facilitate or impede transition of young people from child and adolescent mental health services (CAMHS) to adult mental health services (AMHS) from the perspective of health professionals and representatives of voluntary organisations. Specific objectives were (i) to explore organizational cultures, structures, processes and resources which influence transition from child to adult mental health services; (ii) identify factors which constitute barriers and facilitators to transition and continuity of care and (iii) make recommendations for service improvements. Within an exploratory, qualitative design thirty four semi-structured interviews were conducted with health and social care professionals working in CAMHS and AMHS in four NHS Mental Health Trusts and four voluntary organizations, in England. RESULTS: A cultural divide appears to exist between CAMHS and AMHS, characterized by different beliefs, attitudes, mutual misperceptions and a lack of understanding of different service structures. This is exacerbated by working practices relating to communication and information transfer which could impact negatively on transition, relational, informational and cross boundary continuity of care. There is also evidence of a cultural shift, with some positive approaches to collaborative working across services and agencies, involving joint posts, parallel working, shared clinics and joint meetings. CONCLUSIONS: Cultural factors embodied in mutual misperceptions, attitudes, beliefs exist between CAMHS and AMHS. Working practices can exert either positive or negative effects on transition and continuity of care. Implementation of shared education and training, standardised approaches to record keeping and information transfer, supported by compatible IT resources are recommended, alongside management strategies which evaluate the achievement of outcomes related to transition and continuity of care.

Transfers and transitions between child and adult mental health services.

BACKGROUND: Transfer of care from one healthcare provider to another is often understood as a suboptimal version of the process of transition. AIMS: To separate and evaluate concepts of transfer and transition between child and adolescent mental health services (CAMHS) and adult mental health services (AMHS). METHOD: In a retrospective case-note survey of young people reaching the upper age boundary at six English CAMHS, optimal transition was evaluated using four criteria: continuity of care, parallel care, a transition planning meeting and information transfer. RESULTS: Of 154 cases, 76 transferred to AMHS. Failure to transfer resulted mainly from non-referral by CAMHS (n = 12) and refusal by service users (n = 12) rather than refusal by AMHS (n = 7). Four cases met all criteria for optimal transition, 13 met none; continuity of care (n = 63) was met most often. CONCLUSIONS: Transfer was common but good transition rare. Reasons for failure to transfer differ from barriers to transition. Transfer should be investigated alongside transition in research and service development.

Management of transitions to adult services for young people with eating disorders: survey of current practice in England.

AIMS AND METHOD: The Royal College of Psychiatrists has published recommendations for managing transitions between child and adolescent mental health services (CAMHS) and adult services for eating disorders. A self-report questionnaire was designed to establish how many CAMHS teams meet these recommendations and was distributed to 70 teams providing eating disorders treatment in England. RESULTS: Of the 38 services that participated, 31 (81.6%) reported a flexible upper age limit for treatment. Only 6 services (15.8%) always transferred young people to a specialist adult eating disorders service and the majority transferred patients to either a specialist service or a community mental health team. Most services complied with recommended provision such as a written transition protocol (52.6%), individualised transition plans (78.9%), joint care with adult services (89.5%) and transition support for the family (73.7%). CLINICAL IMPLICATIONS: Services are largely compliant with the recommendations. It is a concern that only a small proportion of services are always able to refer to a specialist adult service and this is likely to be due to a relative lack of investment in adult services.

Healthcare costs for young people transitioning the boundary between child/adolescent and adult mental health services in seven European countries: results from the MILESTONE study.

BACKGROUND: The boundary between services for children and adolescents and adults has been identified as problematic for young people with mental health problems. AIMS: To examine the use and cost of healthcare for young people engaged in mental healthcare before and after the child/adolescent and adult service boundary. METHOD: Data from 772 young people in seven European countries participating in the MILESTONE trial were analysed. We analysed and costed healthcare resources used in the 6-month period before and after the service boundary. RESULTS: The proportion of young people engaging with healthcare services fell substantially after crossing the service boundary (associated costs €7761 pre-boundary v. €3376 post-boundary). Pre-boundary, the main cost driver was in-patient care (approximately 50%), whereas post-boundary costs were more evenly spread between services; cost reductions were correlated with pre-boundary in-patient care. Severity was associated with substantially higher costs pre- and post-boundary, and those who were engaged specifically with mental health services after the service boundary accrued the greatest healthcare costs post-service boundary. CONCLUSIONS: Costs of healthcare are large in this population, but fall considerably after transition, particularly for those who were most severely ill. In part, this is likely to reflect improvement in the mental health of young people. However, qualitative evidence from the MILESTONE study suggests that lack of capacity in adult services and young people's disengagement with formal mental health services post-transition are contributing factors. Long-term data are needed to assess the adverse long-term effects on costs and health of this unmet need and disengagement.
