The impact of the COVID-19 pandemic on 397 631 elective dental admissions among the under-25s in England: a retrospective study.

BACKGROUND: COVID-19 caused widespread disruptions to health services worldwide, including reductions in elective surgery. Tooth extractions are among the most common reasons for elective surgery among children and young people (CYP). It is unclear how COVID-19 affected elective dental surgeries in hospitals over multiple pandemic waves at a national level. METHODS: Elective dental tooth extraction admissions were selected using Hospital Episode Statistics. Admission trends for the first 14 pandemic months were compared with the previous five years and results were stratified by age (under-11s, 11-16s, 17-24s). RESULTS: The most socioeconomically deprived CYP comprised the largest proportion of elective dental tooth extraction admissions. In April 2020, admissions dropped by >95%. In absolute terms, the biggest reduction was in April (11-16s: -1339 admissions, 95% CI -1411 to -1267; 17-24s: -1600, -1678 to -1521) and May 2020 (under-11s: -2857, -2962 to -2752). Admissions differed by socioeconomic deprivation for the under-11s (P < 0.0001), driven by fewer admissions than expected by the most deprived and more by the most affluent during the pandemic. CONCLUSION: Elective tooth extractions dropped most in April 2020, remaining below pre-pandemic levels throughout the study. Despite being the most likely to be admitted, the most deprived under-11s had the largest reductions in admissions relative to other groups.

Impact of the COVID-19 pandemic on the clinical management trends for acute appendicitis among the under-25s: a retrospective study.

OBJECTIVE: To describe the COVID-19 pandemic's impact on acute appendicitis management on children and young people (CYP). DESIGN: Retrospective cohort study. SETTING: All English National Health Service hospitals. PATIENTS: Acute appendicitis admissions (all, simple, complex) by CYP (under-5s, 5-9s, 10-24s). EXPOSURE: Study pandemic period: February 2020-March 2021. Comparator pre-pandemic period: February 2015-January 2020. MAIN OUTCOME MEASURES: Monthly appendicectomy and laparoscopic appendicectomy rate trends and absolute differences between pandemic month and the pre-pandemic average. Proportions of appendicitis admissions comprising complex appendicitis by hospital with or without specialist paediatric centres were compared. RESULTS: 101 462 acute appendicitis admissions were analysed. Appendicectomy rates fell most in April 2020 for the 5-9s (-18.4% (95% CI -26.8% to -10.0%)) and 10-24s (-28.4% (-38.9% to -18.0%)), driven by reductions in appendicectomies for simple appendicitis. This was equivalent to -54 procedures (-68.4 to -39.6) and -512 (-555.9 to -467.3) for the 5-9s and 10-24s, respectively. Laparoscopic appendicectomies fell in April 2020 for the 5-9s (-15.5% (-23.2% to -7.8%)) and 10-24s (-44.8% (-57.9% to -31.6%) across all types, which was equivalent to -43 (-56.1 to 30.3) and -643 (-692.5 to -593.1) procedures for the 5-9s and 10-24s, respectively. A larger proportion of complex appendicitis admissions were treated within trusts with specialist paediatric centres during the pandemic. CONCLUSIONS: For CYP across English hospitals, a sharp recovery followed a steep reduction in appendicectomy rates in April 2020, due to concerns with COVID-19 transmission. This builds on smaller-sized studies reporting the immediate short-term impacts.

Mental health interventions for children and young people with long-term health conditions in Children and Young People's Mental Health Services in England.

BACKGROUND: Almost a quarter of children and young people (CYP) in England have a long-term health condition (LTC), which increases the risk of developing mental health difficulties. There is a lack of understanding regarding the routine provision and efficacy of mental health interventions for CYP with LTCs within Children and Young People's Mental Health Services (CYPMHS). METHODS: This study analysed national service-reported data in England from two secondary datasets. Data were submitted by services between 2011 and 2019. We evaluated data on the presence or absence of a serious physical health or neurological issue, and which interventions were offered. RESULTS: A total of 789 CYP had serious physical health issues and 635 had neurological issues. The most common interventions delivered to CYP in either group have some evidence in the literature. Most CYP showed improvements across a range of outcomes. CONCLUSIONS: This study found that prevalence rates and psychological intervention and outcome data were widely under-reported across both datasets, posing questions about their utility for this population. Such data would benefit from triangulation with data from other sources to understand pathways of care for these young people and the extent to which clinical datasets underreport the number of CYP with LTCs.

Almost a quarter of children and young people (CYP) in England have a long-term health condition (LTC), such as asthma, diabetes, or epilepsy. We know that these young people are at increased risk of developing mental health difficulties. It is important these young people are able to access safe and effective treatments for their mental health. Therefore, they are sometimes referred to Children and Young People's Mental Health Services (CYPMHS) for appropriate treatment. However, at the moment, not much is known about the types of mental health support these services offer to children with co-existing physical health needs, or if this support is effective. The aim of this study was to try and find this out. We used data that had already been collected from mental health services across England. We looked at specific parts of this data that gave us information about the type of mental health treatments delivered to children with a long-term health condition. We separated long-term health conditions into two categories: physical health, such as diabetes or asthma; and neurological, such as epilepsy. In the sample we looked at, a range of mental health treatments were delivered to young people in both groups. Encouragingly, many of the young people's mental health improved. However, a lot of information we would hope to find was not available in the datasets. Also, the number of children with a long-term health condition was much lower than we expected. This might have been for a number of reasons, which we recommend other future research tries to find out. Going forward, it is important to think about how to make sure that accurate information about these children is collected from mental health services. This will help ensure that the right decisions are made for the care of young people with long-term health conditions.

Evaluating the implementation and impact of a new model of care for integrating children and young people's acute mental healthcare in a paediatric setting: a protocol for a realist, mixed-methods approach.

INTRODUCTION: The mental health of children and young people in the UK has been declining and has continued to worsen throughout the pandemic, leading to an increase in mental health-related emergencies. In response, the Best for You programme was developed as a new service designed to integrate mental healthcare for children and young people between acute hospital and community services. The programme is comprised of four new services: a rapid assessment young people's centre with dual-trained staff, a co-located day service offering family-based care,a digital hub, designed to integrate with the fourth element of the model, namely community support and mental health services. This evaluation protocol aims to assess the development, implementation and outcomes of the Best for You programme and develops a scalable model that could be implemented in other parts of the National Health Service (NHS). METHODS AND ANALYSIS: This mixed-methods realist evaluation aims to delineate the components of the system to assess their interdependent relationships within a wider context. Data collection will include interviews, participant observations, focus groups and the collection of local quantitative healthcare data. The research will be conducted across four phases. Phase 1-captures the development of the underlying programme theory. Phase 2-a process evaluation testing the programme theory. Phase 3- an outcome and economic evaluation. Phase 4-consolidation of learning from phases 1-3 to identify barriers, facilitators and wider contextual factors that have shaped implementation drawing on the Consolidated Framework for Implementation Research. ETHICS AND DISSEMINATION: Ethical approval for the evaluation was received from the NHS local ethics committee. Embedded within the evaluation is a formative review to feedback and share learning with stakeholders to scale-up the programme. Findings from this study will be disseminated in peer-reviewed journals as well as presentations to be useful to service user organisations and networks.

Developing a core outcome set for physical activity interventions in primary schools: a modified-Delphi study.

OBJECTIVES: To develop a core outcome set (COS) for physical activity interventions in primary schools. DESIGN: Modified-Delphi study. SETTING: The UK and international. PARTICIPANTS: 104 participants from four stakeholder groups (educators, public health professionals, health researchers, parents); 16 children (aged 8-9 years) from 1 London primary school. INTERVENTIONS: Physical activity interventions. METHODS: Four-stage process: (1) outcomes extracted from relevant studies identified from an umbrella review and a focus group; (2) list of outcomes produced and domains established; (3) stakeholders completed a two-round Delphi survey by rating (Round 1) and re-rating (Round 2) each outcome on a nine-point Likert Scale from 'not important' to 'critical': a>70% participant threshold identified the outcomes rated 'critical' to measure, and outcomes important to children were identified through a workshop; and (4) a stakeholder meeting to achieve consensus of the outcomes to include in the COS. RESULTS: In total, 74 studies were extracted from 53 reviews. A list of 50 outcomes was produced and three domains were established: 'physical activity and health' (16 outcomes), 'social and emotional health' (22 outcomes) and 'educational performance' (12 outcomes). 104 participants completed survey Round 1; 65 participants completed both rounds. In total, 13 outcomes met the threshold; children identified 8 outcomes. Fourteen outcomes achieved consensus to produce the COS: five outcomes for physical activity and health (diet (varied and balanced), energy, fitness, intensity of physical activity, sleep (number of hours)); seven outcomes for social and emotional health (anxiety, depression, enjoyment, happiness, self-esteem, stress, well-being); and two outcomes for educational performance (concentration, focus). CONCLUSIONS: We have developed the first COS for physical activity interventions in primary schools in consultation with those interested in the development and application of an agreed standardised set of outcomes. Future studies including these outcomes will reduce heterogeneity across studies.

Back to the future? Lessons from the history of integrated child health services in England.

The UK has a long history of attempts to integrate child health services to improve outcomes, an ambition renewed in the recent The NHS Long Term Plan. It's therefore timely to review the history of integration to inform future initiatives. Key milestones include the Platt report (1959), Court report (1976), Sure Start (1999), National service framework (2004) and Facing the future report (2015). These stand against a backdrop of national NHS policy changes, with a myriad of local integration initiatives and research efforts in parallel. We suggest lessons for future integration initiatives: integration may support the quadruple aim; integration depends on addressing divides between primary and secondary care; workforce and funding challenges need to be resolved before integration can thrive; high-quality research and evaluation of integrated interventions is required; strong relationships between professional groups are key to integration; and integration can help address health inequalities.

Impact of COVID-19 on outpatient appointments in children and young people in England: an observational study.

OBJECTIVES: To describe the impact of the COVID-19 pandemic on outpatient appointments for children and young people. SETTING: All National Health Service (public) hospitals in England. PARTICIPANTS: All people in England aged <25 years. OUTCOME MEASURES: Outpatient department attendance numbers, rates and modes (face to face vs telephone) by age group, sex and socioeconomic deprivation. RESULTS: Compared with the average for January 2017 to December 2019, there was a 3.8 million appointment shortfall (23.5%) for the under-25 population in England between March 2020 and February 2021, despite a total rise in phone appointments of 2.6 million during that time. This was true for each age group, sex and deprivation fifth, but there were smaller decreases in face to face and total appointments for babies under 1 year. For all ages combined, around one in six first and one in four follow-up appointments were by phone in the most recent period. The proportion of appointments attended was high, at over 95% for telephone and over 90% for face-to-face appointments for all ages. CONCLUSIONS: COVID-19 led to a dramatic fall in total outpatient appointments and a large rise in the proportion of those appointments conducted by telephone. The impact that this has had on patient outcomes is still unknown. The differential impact of COVID-19 on outpatient activity in different sociodemographic groups may also inform design of paediatric outpatient services in the post-COVID period.

Impact of COVID-19 on primary care contacts with children and young people in England: longitudinal trends study 2015-2020.

BACKGROUND: The NHS response to COVID-19 altered provision and access to primary care. AIM: To examine the impact of COVID-19 on GP contacts with children and young people (CYP) in England. DESIGN AND SETTING: A longitudinal trends analysis was undertaken using electronic health records from the Clinical Practice Research Datalink (CPRD) Aurum database. METHOD: All CYP aged <25 years registered with a GP in the CPRD Aurum database were included. The number of total, remote, and face-to-face contacts during the first UK lockdown (March to June 2020) were compared with the mean contacts for comparable weeks from 2015 to 2019. RESULTS: In total, 47 607 765 GP contacts with 4 307 120 CYP were included. GP contacts fell 41% during the first lockdown compared with previous years. Children aged 1-14 years had greater falls in total contacts (≥50%) compared with infants and those aged 15-24 years. Face-to-face contacts fell by 88%, with the greatest falls occurring among children aged 1-14 years (>90%). Remote contacts more than doubled, increasing most in infants (over 2.5-fold). Total contacts for respiratory illnesses fell by 74% whereas contacts for common non-transmissible conditions shifted largely to remote contacts, mitigating the total fall (31%). CONCLUSION: During the COVID-19 pandemic, CYP's contact with GPs fell, particularly for face-to-face assessments. This may be explained by a lower incidence of respiratory illnesses because of fewer social contacts and changing health-seeking behaviour. The large shift to remote contacts mitigated total falls in contacts for some age groups and for common non-transmissible conditions.

Patterns of healthcare utilisation in children and young people: a retrospective cohort study using routinely collected healthcare data in Northwest London.

OBJECTIVES: With a growing role for health services in managing population health, there is a need for early identification of populations with high need. Segmentation approaches partition the population based on demographics, long-term conditions (LTCs) or healthcare utilisation but have mostly been applied to adults. Our study uses segmentation methods to distinguish patterns of healthcare utilisation in children and young people (CYP) and to explore predictors of segment membership. DESIGN: A retrospective cohort study. SETTING: Routinely collected primary and secondary healthcare data in Northwest London from the Discover database. PARTICIPANTS: 378 309 CYP aged 0-15 years registered to a general practice in Northwest London with 1 full year of follow-up. PRIMARY AND SECONDARY OUTCOME MEASURES: Assignment of each participant to a segment defined by seven healthcare variables representing primary and secondary care attendances, and description of utilisation patterns by segment. Predictors of segment membership described by age, sex, ethnicity, deprivation and LTCs. RESULTS: Participants were grouped into six segments based on healthcare utilisation. Three segments predominantly used primary care, two moderate utilisation segments differed in use of emergency or elective care, and a high utilisation segment, representing 16 632 (4.4%) children accounted for the highest mean presentations across all service types. The two smallest segments, representing 13.3% of the population, accounted for 62.5% of total costs. Younger age, residence in areas of higher deprivation and the presence of one or more LTCs were associated with membership of higher utilisation segments, but 75.0% of those in the highest utilisation segment had no LTC. CONCLUSIONS: This article identifies six segments of healthcare utilisation in CYP and predictors of segment membership. Demographics and LTCs may not explain utilisation patterns as strongly as in adults, which may limit the use of routine data in predicting utilisation and suggest children have less well-defined trajectories of service use than adults.

Early-life maternal attachment and risky health behaviours in adolescence: findings from the United Kingdom Millennium Cohort Study.

BACKGROUND: Early uptake of multiple risky behaviours during adolescence, such as substance use, antisocial and sexual behaviours, can lead to poor health outcomes without timely interventions. This study investigated how early-life maternal attachment, or emotional bonds between mothers and infants, influenced later risky behaviours in adolescence alongside other potential explanatory pathways using the United Kingdom Millennium Cohort Study. METHODS: Total maternal attachment scores measured at 9 months using the Condon (1998) Maternal Postnatal Attachment Scale compared higher and lower attachment, where mothers in the lowest 10th percentile represented lower attachment. Multiple risky behaviours, defined as two or more risky behaviours (including smoking cigarettes, vaping, alcohol consumption, illegal drug use, antisocial behaviour, criminal engagement, unsafe sex, and gambling), were scored from 0 to 8 at age 17. Five multivariate logistic regression models examined associations between maternal attachment and multiple risky behaviours among Millennium Cohort Study members (n = 7796). Mediation analysis sequentially adjusted for blocks of explanatory mechanisms, including low attachment mechanisms (multiple births, infant prematurity, sex, breastfeeding, unplanned pregnancy and maternal age at birth), maternal depression, and social inequalities (single-parent status, socioeconomic circumstance by maternal education and household income) at 9 months and poor adolescent mental health at 14 years. RESULTS: Children of mothers with lower maternal attachment at 9 months had 23% increased odds of multiple risky behaviours at 17 years (OR: 1.23, 95% CI: 1.00-1.50) in the unadjusted baseline model. All five explanatory blocks attenuated baseline odds. Low attachment mechanisms attenuated 13%, social inequalities 17%, and poor mental health 17%. Maternal depression attenuated the highest proportion (26%) after fully adjusting for all factors (30%). CONCLUSIONS: Lower maternal attachment in early life predicted increased adolescent multiple risky behaviours. Almost a third of the excess risk was attributable to child, maternal and socioeconomic factors, with over a quarter explained by maternal depression. Recognising the influence of early-life risk factors on adolescent health could innovate current policies and interventions addressing multiple risky behaviour uptake affecting health inequalities across the life course.

Impact of The Daily Mile on children's physical and mental health, and educational attainment in primary schools: iMprOVE cohort study protocol.

INTRODUCTION: School-based active mile initiatives such as The Daily Mile (TDM) are widely promoted to address shortfalls in meeting physical activity recommendations. The iMprOVE Study aims to examine the impact of TDM on children's physical and mental health and educational attainment throughout primary school. METHODS AND ANALYSIS: iMprOVE is a longitudinal quasi-experimental cohort study. We will send a survey to all state-funded primary schools in Greater London to identify participation in TDM. The survey responses will be used for non-random allocation to either the intervention group (Daily Mile schools) or to the control group (non-Daily Mile schools). We aim to recruit 3533 year 1 children (aged 5-6 years) from 77 primary schools and follow them up annually until the end of their primary school years. Data collection taking place at baseline (children in school year 1) and each primary school year thereafter includes device-based measures of moderate-to-vigorous physical activity (MVPA) and questionnaires to measure mental health (Strengths and Difficulties Questionnaire) and educational attainment (ratings from 'below expected' to 'above expected levels'). The primary outcome is the mean change in MVPA minutes from baseline to year 6 during the school day among the intervention group compared with controls. We will use multilevel linear regression models adjusting for sociodemographic data and participation in TDM. The study is powered to detect a 10% (5.5 min) difference between the intervention and control group which would be considered clinically significant. ETHICS AND DISSEMINATION: Ethics has been approved from Imperial College Research Ethics Committee, reference 20IC6127. Key findings will be disseminated to the public through research networks, social, print and media broadcasts, community engagement opportunities and schools. We will work with policy-makers for direct application and impact of our findings.

A cross-sectional study using the Childhood Measurement Programme for Wales to examine population-level risk factors associated with childhood obesity.

OBJECTIVE: The aim of this cross-sectional study was to examine the association between childhood obesity and modifiable population-level risk factors, after accounting for deprivation. DESIGN: A review of the literature identified population-level risk factors including a healthy childcare setting, the local food environment, accessible open space, community safety and crime. Data for these risk factors were then identified and matched by each of the twenty-two local government areas in Wales to each child that had data on height and weight in the Wales Childhood Measurement Programme (CMP) (2012-2017). Multivariable logistic regression was used to identify associations with childhood obesity. SETTING: The current study was undertaken in Wales, UK, where approximately one in eight 4-5-year-olds are classified as obese. PARTICIPANTS: All participants were children aged 4 or 5 years who attend school, measured as part of the CMP, between 2012 and 2017 (n 129 893, mean age 5·0 (sd 0·4) years). RESULTS: After adjusting for deprivation, small but statistically significant associations were found between childhood obesity and percentage of land available as accessible open space OR 0·981 (95 % CI: 0·973, 0·989) P < 0·001) and density of fast food outlets OR 1·002 (95 % CI 1·001, 1·004, P = 0·001). No other population-level risk factors were associated with childhood obesity. CONCLUSIONS: The current study indicates that, even after accounting for deprivation, risk factors such as the density of fast food outlets and access to green space should be considered when tackling childhood obesity as a public health issue.

Trends in healthcare use in children aged less than 15 years: a population-based cohort study in England from 2007 to 2017.

OBJECTIVE: To describe changing use of primary care in relation to use of urgent care and planned hospital services by children aged less than 15 years in England in the decade following major primary care reforms from 2007 to 2017 DESIGN: Population-based retrospective cohort study. METHODS: We used linked data from the Clinical Practice Research Datalink to study children's primary care consultations and use of hospital care including emergency department (ED) visits, emergency and elective admissions to hospital and outpatient visits to specialists. RESULTS: Between 1 April 2007 and 31 March 2017, there were 7 604 024 general practitioner (GP) consultations, 981 684 ED visits, 287 719 emergency hospital admissions, 2 253 533 outpatient visits and 194 034 elective admissions among 1 484 455 children aged less than 15 years. Age-standardised GP consultation rates fell (-1.0%/year) to 1864 per 1000 child-years in 2017 in all age bands except infants rising by 1%/year to 6722 per 1000/child-years in 2017. ED visit rates increased by 1.6%/year to 369 per 1000 child-years in 2017, with steeper rises of 3.9%/year in infants (780 per 1000 child-years in 2017). Emergency hospital admission rates rose steadily by 3%/year to 86 per 1000 child-years and outpatient visit rates rose to 724 per 1000 child-years in 2017. CONCLUSIONS: Over the past decade since National Health Service primary care reforms, GP consultation rates have fallen for all children, except for infants. Children's use of hospital urgent and outpatient care has risen in all ages, especially infants. These changes signify the need for better access and provision of specialist and community-based support for families with young children.

Protocol for developing a core outcome set for evaluating school-based physical activity interventions in primary schools.

INTRODUCTION: Primary school-based physical activity interventions, such as The Daily Mile initiative, have the potential to increase children's physical activity levels over time, which is associated with a variety of health benefits. Comparing interventions or combining results of several studies of a single intervention is challenging because previous studies have examined different outcomes or used different measures that are not feasible or relevant for researchers in school settings. The development and implementation of a core outcome set (COS) for primary school-based physical activity interventions would ensure outcomes important to those involved in implementing and evaluating interventions are standardised. METHODS AND ANALYSIS: Our aim is to develop a COS for studies of school-based physical activity interventions. We will achieve this by undertaking a four-stage process:(1) identify a list of outcomes assessed in studies through a systematic review of international literature; (2) establish domains from these outcomes to produce questionnaire items; (3) prioritise outcomes through a two-stage Delphi survey with four key stakeholder groups (researchers, public health professionals, educators and parents), where stakeholders rate the importance of each outcome on a 9-point Likert scale (consensus that the outcomes should be included in the COS will be determined as 70% or more of all stakeholders scoring the outcome 7%-9% and 15% or less scoring 1 to 3); (4) achieve consensus on a final COS in face-to-face meetings with a sample of stakeholders and primary school children. ETHICS AND DISSEMINATION: We have received ethical approval from Imperial College London (ref: 19IC5428). The results of this study will be disseminated via conference presentations/public health meetings, peer-reviewed publications and through appropriate media channels. TRIAL REGISTRATION NUMBER: Core Outcome Measures in Effectiveness Trials Initiative (COMET) number: 1322.

Association of quality of paediatric epilepsy care with mortality and unplanned hospital admissions among children and young people with epilepsy in England: a national longitudinal data linkage study.

BACKGROUND: Concerns have been raised about variation in care quality and outcomes among children and young people with epilepsies in England. We aimed to investigate the association between quality of paediatric care, hospital admissions, and all-cause deaths among epilepsy patients. METHODS: In this longitudinal data linkage study of paediatric epilepsy services in England, we linked unit-level data from round 1 (2009-11) and round 2 (2013-14) of the Epilepsy12 national clinical audit, with death registrations from the UK Office for National Statistics and data for unplanned hospital admissions from Hospital Episode Statistics. We investigated the association between unit-level performance in involving a paediatrician with epilepsy expertise, an epilepsy specialist nurse, and a paediatric neurologist (where appropriate) in round 1 and the proportion of adolescents (aged 10-18 years) with epilepsy admitted to each unit who subsequently died during the study period (April 1, 2009, to March 31, 2015). We also investigated whether change in Epilepsy12 performance between the two audit rounds was associated with changes in the standardised ratio of observed-to-expected unplanned epilepsy admissions over the same period. FINDINGS: In 99 units with data for the analyses relating to paediatricians with epilepsy expertise and epilepsy specialist nurses, 134 (7%) of 1795 patients died during the study period, 88 (5%) of whom died after the transition to adult service. In 55 units with data for the analyses relating to paediatric neurologists, 79 (7%) of 1164 patients died, 54 (5%) of whom did so after the transition. In regression models adjusting for population, unit, and hospital activity characteristics, absolute reductions in total mortality risk (6·4 percentage points, 95% CI 0·1-12·7) and mortality risk after transition (5·7 percentage points, 0·6-10·8) were found when comparing units where all versus no eligible patients were seen by a paediatric neurologist. Units where all eligible patients were seen by a paediatric neurologist were estimated to have absolute reductions of 4·6 percentage points (0·3-8·9) in total mortality and of 4·6 percentage points (1·2-8·0) in post-transition mortality, compared with units where no or some eligible patients were seen by a paediatric neurologist. There was no significant association between performance on being seen by an epilepsy specialist nurse or by a paediatrician with epilepsy expertise and mortality. In units where access to an epilepsy specialist nurse decreased, the standardised ratio of epilepsy admissions increased by a mean of 0·21 (0·01-0·42). INTERPRETATION: Among adolescents with epilepsy, greater involvement of tertiary specialists in paediatric care is associated with decreased all-cause mortality in the period after transition to adult services. Reduced access to an epilepsy specialist nurse was associated with an increase in paediatric epilepsy admissions. FUNDING: The Health Foundation.
