A longitudinal, observational study of the features of transitional healthcare associated with better outcomes for young people with long-term conditions.

BACKGROUND: Most evidence about what works in transitional care comes from small studies in single clinical specialties. We tested the hypothesis that exposures to nine recommended features of transitional healthcare were associated with better outcomes for young people with long-term conditions during transition from child-centred to adult-oriented health services. METHODS: This is a longitudinal, observational cohort study in UK secondary care including 374 young people, aged 14-18.9 years at recruitment, with type 1 diabetes (n = 150), cerebral palsy (n = 106) or autism spectrum disorder with an associated mental health problem (n = 118). All were pre-transfer and without significant learning disability. We approached all young people attending five paediatric diabetes centres, all young people with autism spectrum disorder attending four mental health centres, and randomly selected young people from two population-based cerebral palsy registers. Participants received four home research visits, 1 year apart and 274 participants (73%) completed follow-up. Outcome measures were Warwick Edinburgh Mental Wellbeing Scale, Mind the Gap Scale (satisfaction with services), Rotterdam Transition Profile (Participation) and Autonomy in Appointments. RESULTS: Exposure to recommended features was 61% for 'coordinated team', 53% for 'age-banded clinic', 48% for 'holistic life-skills training', 42% for 'promotion of health self-efficacy', 40% for 'meeting the adult team before transfer', 34% for 'appropriate parent involvement' and less than 30% for 'written transition plan', 'key worker' and 'transition manager for clinical team'. Three features were strongly associated with improved outcomes. (1) 'Appropriate parent involvement', example association with Wellbeing (b = 4.5, 95% CI 2.0-7.0, p = 0.001); (2) 'Promotion of health self-efficacy', example association with Satisfaction with Services (b = - 0.5, 95% CI - 0.9 to - 0.2, p = 0.006); (3) 'Meeting the adult team before transfer', example associations with Participation (arranging services and aids) (odds ratio 5.2, 95% CI 2.1-12.8, p < 0.001) and with Autonomy in Appointments (average 1.7 points higher, 95% CI 0.8-2.6, p < 0.001). There was slightly less recruitment of participants from areas with greater socioeconomic deprivation, though not with respect to family composition. CONCLUSIONS: Three features of transitional care were associated with improved outcomes. Results are likely to be generalisable because participants had three very different conditions, attending services at many UK sites. Results are relevant for clinicians as well as for commissioners and managers of health services. The challenge of introducing these three features across child and adult healthcare services, and the effects of doing so, should be assessed.

Parents in transition: Experiences of parents of young people with a liver transplant transferring to adult services.

Predictors of successful transition from pediatric to adult services include ability to self-manage and engage with healthcare services. Parents have a key role in healthcare management throughout childhood and adolescence including encouraging development of self-management skills in their children. Transition to adult services can be challenging for parents and young people, yet parents' views regarding transition remain largely unexplored. Nine parents of pediatric liver transplant recipients (15.2-25.1 yr) participated in semistructured interviews. Interviews were analyzed using IPA. Analysis revealed three key themes: "emotional impact of transplantation," "protection vs. independence," and "ending relationships and changing roles." Parents expressed the dichotomous nature of the desire to promote independence in their child while still maintaining control and protection, and discussed how changing roles and relationships were difficult to navigate. Parents are important facilitators of young people's development of self-management skills for successful transfer to adult services. Parents should be supported to move from a "managerial" to a "supervisory" role during transition to help young people engage independently with the healthcare team. Findings support the development of interventions for parents to emphasize their role in transition and guide the transfer of self-management skills from parent to young person.

"Sometimes I feel like a pharmacist": identity and medication use among adolescents with juvenile arthritis.

BACKGROUND: Taking medicines as intended is difficult for everybody, but young people going through adolescence have greater problems than adults and younger children. One of the most important things that happen during the teenage years is the development of individual identities, which might not remain constant during this time and can be affected deeply by the diagnosis of a long-term condition. The aim of this study was to examine the relationships between identity and medication use among young people with juvenile arthritis. METHODS: A prospective qualitative study was undertaken to collect private online 'blog' style data from young people (aged 11-19 years) with juvenile arthritis, and their parents, to examine their views about their condition, identity, medication and use of health services. Participants were identified from a large paediatric hospital in the UK. RESULTS: Young people (n = 21) with a median age 14 years (range 11-17 years) posted a median (range) of 8 (1-36) blogs and parents (n = 6) posted 4 (1-12) blogs. Young people gave a strong sense of both private and public identity that was intertwined with their arthritis and treatment. It was evident that young people's self-care was intrinsically linked to their attempts to maintain a sense of individually and socially constructed definitions of normality. The act of taking medication, and the consequences (positive or negative) of that act, had an impact both personally and socially. CONCLUSIONS: Young people with juvenile arthritis reflect on their medication as a factor affecting their perception of themselves. Acknowledging the roles of both personal and social identity will be important in any strategies to support optimal medication use. This includes an understanding of the identity transformations that young people can experience and how decision-making may be affected by their attempts to retain pre-diagnosis identities and/or develop new social identities.

"Are these adult doctors gonna know me?" Experiences of transition for young people with a liver transplant.

Excellent survival rates in paediatric LTx have resulted in increasing numbers of young people transferring from paediatric to adult care. Understanding the mechanisms of successful transition is imperative for ensuring good long-term outcomes and developing services for young people. Semi-structured interviews were conducted with 17 young people (10 females; age range: 15.2-25.1 years). Eight were within 1 year of transferring to adult services; nine had transferred. Interviews were analysed using IPA. Analysis revealed two major themes in both pre- and post-transfer groups: "relationships with healthcare professionals" and "continuity of care." Young people experienced difficulty ending relationships with paediatric clinicians and forming new relationships with adult clinicians. They expressed frustrations over a perceived lack of continuity of care after transfer and a fear of the unknown nature of adult services. The importance of a holistic approach to care was emphasized. Interventions are needed to support young people in transition, particularly in ending relationships in paediatric care and forming new relationships in adult care. Young people need help to develop strategies to cope with the different approaches in adult services. Interventions to provide clinicians with skills to communicate and engage with young people are imperative.

A review of methods for the calculation of solution free energies and the modelling of systems in solution.

Over the past decade, pharmaceutical companies have seen a decline in the number of drug candidates successfully passing through clinical trials, though billions are still spent on drug development. Poor aqueous solubility leads to low bio-availability, reducing pharmaceutical effectiveness. The human cost of inefficient drug candidate testing is of great medical concern, with fewer drugs making it to the production line, slowing the development of new treatments. In biochemistry and biophysics, water mediated reactions and interactions within active sites and protein pockets are an active area of research, in which methods for modelling solvated systems are continually pushed to their limits. Here, we discuss a multitude of methods aimed towards solvent modelling and solubility prediction, aiming to inform the reader of the options available, and outlining the various advantages and disadvantages of each approach.

Predicting Melting Points of Organic Molecules: Applications to Aqueous Solubility Prediction Using the General Solubility Equation.

In this work we make predictions of several important molecular properties of academic and industrial importance to seek answers to two questions: 1) Can we apply efficient machine learning techniques, using inexpensive descriptors, to predict melting points to a reasonable level of accuracy? 2) Can values of this level of accuracy be usefully applied to predicting aqueous solubility? We present predictions of melting points made by several novel machine learning models, previously applied to solubility prediction. Additionally, we make predictions of solubility via the General Solubility Equation (GSE) and monitor the impact of varying the logP prediction model (AlogP and XlogP) on the GSE. We note that the machine learning models presented, using a modest number of 2D descriptors, can make melting point predictions in line with the current state of the art prediction methods (RMSE≥40 °C). We also find that predicted melting points, with an RMSE of tens of degrees Celsius, can be usefully applied to the GSE to yield accurate solubility predictions (log10 S RMSE<1) over a small dataset of drug-like molecules.

Walking the talk. Implementation of transitional care guidance in a UK paediatric and a neighbouring adult facility.

OBJECTIVES: To examine the quality of transitional care in a paediatric and adult hospital by investigating (i) adherence to national transition guidance and (ii) whether implementation is associated with better patient/carer experiences. METHODS: A cross-sectional study was conducted in a UK paediatric hospital (PH) and neighbouring adult hospital. Clinics completed a questionnaire to determine characteristics of their transitional care provision and invited patients aged 11-21 years and parents/carers to complete a questionnaire ('Mind the Gap') to assess their satisfaction. RESULTS: Twenty-three clinics participated. Fourteen (70%) reported delivering a transition programme, but only 5 (25%) indicated this was holistic (addressing medical, psychosocial and vocational issues). Participants included 457 young people and 330 parents, 71% and 88% respectively attending the PH. Ratings of current care were significantly lower than ratings of best care. These 'gap' scores were not excessive, although some participants were very dissatisfied. Better satisfaction was associated with attending clinics that provided transitional care, especially when defined as 'holistic' and youth-friendly. CONCLUSIONS: Transition programmes that adhere to current guidance are associated with better satisfaction, but variations in provision suggest barriers to implementation. Attention is required to how youth-friendly transitional care is defined with particular reference to the specific clinic model.

The challenges and opportunities for transitional care research.

The provision of healthcare for young people with solid organ transplants as they move into adult-centered services has received increasing attention over recent years particularly as non-adherence and graft loss increase after transfer. Despite medical advances and that transitional care is now well established on national and international health agendas, progress in the research arena has unfortunately been slow. The aims of this paper are to consider why this is and discuss the particular challenges facing clinical researchers working within the area.

Young people's satisfaction of transitional care in adolescent rheumatology in the UK.

BACKGROUND: To examine the quality of transitional health care from the perspectives of young people with juvenile idiopathic arthritis (JIA) and their parents. METHODS: Adolescents with JIA and their parents were recruited from 10 major UK rheumatology centres. Satisfaction with health-care delivery was measured prior to, and 12 months after, the implementation of a structured and co-ordinated programme of transitional care using self-completed questionnaires designed for this study. RESULTS: Of 359 families invited to participate, 308 (86%) adolescents with JIA and 303 (84%) parents/guardians accepted. A fifth of adolescents had persistent oligoarthritis. Median age was 14.2 (11-18) years with median disease duration of 5.7 (0-16) years. Young people and their parents rated provider characteristics more important than aspects of the physical environment or process issues. Staff honesty and knowledge were rated as the most essential aspects of best practice. Prior to implementing the programme of transitional care, parents rated service delivery for all items significantly worse than best practice. Overall satisfaction improved 12 months after entering the programme. However, while parent satisfaction improved for 70.4% of items, significant improvements were only observed for three (13.6%) items rated by adolescents. CONCLUSION: The perceived quality of health care for young people with JIA and their parents was significantly lower than what they would like. Satisfaction with many aspects of care during transition from paediatric to adult services can be improved through the implementation of a structured, co-ordinated programme of transitional care.

Development and preliminary validation of the 'Mind the Gap' scale to assess satisfaction with transitional health care among adolescents with juvenile idiopathic arthritis.

BACKGROUND: To develop a scale to assess satisfaction with transitional health care among adolescents with a chronic illness and their parents. METHODS: The 'Mind the Gap' scale was developed using evidence from a previous needs assessment, in three stages: (1) definition of the construct; (2) design of the scale items, response options and instructions; (3) full administration of the scale, item analysis and dimensionality analysis. The scale was administered to 308 adolescents with juvenile idiopathic arthritis (JIA) and 303 parents/guardians, prior to and 12 months after the implementation of an evaluation of a structured and co-ordinated programme of transitional care. The patient population involved adolescents with JIA and their parents recruited from 10 major UK rheumatology centres. RESULTS: A total of 301 (97.7%) adolescents and 286 (95.0%) parents chose to complete the questionnaire, with median item completion rates of 100.0% (0-100%) for both adolescents and parents thus confirming feasibility. Face and content validity were confirmed. Factor analyses revealed a three-factor structure which explained 49.5% and 56.1% of the variation in adolescent and parent scores respectively. The internal consistency of each subscale ('management of environment', 'provider characteristics' and 'process issues') was indicated by Cronbach's alphas of 0.71, 0.89 and 0.89 for adolescents, respectively, and 0.83, 0.91 and 0.92 for parents respectively. Cronbach's alphas for the entire scales were 0.91 and 0.94 for the adolescent and parent forms respectively. CONCLUSION: These preliminary results report the potential of the 'Mind the Gap' scale in evaluating transitional care for adolescents with JIA. In view of the generic nature of transitional care reflected in the scale, this scale has wider potential for use with adolescents with other chronic illness in view of the generic nature of transition. This development is particularly timely in the context of transitional care developments in the UK and further validation of the scale is in progress.

The impact of a coordinated transitional care programme on adolescents with juvenile idiopathic arthritis.

OBJECTIVE: There is an extensive evidence base for the need of transitional care, but a paucity of robust outcome data. The aim of the study was to determine whether the quality of life of adolescents with juvenile idiopathic arthritis (JIA) could be improved by a co-ordinated, evidence-based programme of transitional care. METHODS: Adolescents with JIA aged 11, 14 and 17 yrs and their parents were recruited from 10 rheumatology centres in the UK. Data were collected at baseline, 6 and 12 months including core outcome variables. The primary outcome measure was health-related quality of life (HRQL): Juvenile Arthritis Quality of Life Questionnaire (JAQQ). Secondary outcome measures included: knowledge, satisfaction, independent health behaviours and pre-vocational experience. RESULTS: Of the 359 families invited to participate, 308 (86%) adolescents and 303 (84%) parents accepted. A fifth of them had persistent oligoarthritis. Median disease duration was 5.7 (0-16) yrs. Compared with baseline values, significant improvements in JAQQ scores were reported for adolescent and parent ratings at 6 and 12 months and for most secondary outcome measures with no significant deteriorations between 6 and 12 months. Continuous improvement was observed for both adolescent and parent knowledge with significantly greater improvement in the younger age groups at 12 months (P = 0.002). CONCLUSIONS: This study represents the first objective evaluation of an evidence-based transitional care programme and demonstrates that such care can potentially improve adolescents' HRQL.

Clinical assessment and core outcome variables are poor predictors of hip arthritis diagnosed by MRI in juvenile idiopathic arthritis.

OBJECTIVES: To compare the diagnostic performance of clinical assessment against magnetic resonance imaging (MRI) diagnosed hip arthritis in a juvenile idiopathic arthritis (JIA) population. To determine the clinical and serological predictors of MRI diagnosed hip arthritis. METHODS: A total of 34 JIA patients with established disease (mean disease duration 6.3 yrs) had their hip MRIs scored for features of active hip arthritis and hip damage. Results were compared with clinical variables (disease subtype, history of hip pain, core outcome variables (COV)) and the clinician's assessment of active hip arthritis. RESULTS: MRI features of active hip arthritis were found in 45 hips (70%) and hip damage in 36 hips (56%). Clinical assessment had fair agreement with MRI scoring of active arthritis in patients with disease duration <4 yrs (kappa score 0.38, P = 0.045). Clinical assessment had a sensitivity of 25.7% and specificity of 91% for detecting MRI diagnosed arthritis. Of the core outcome variables only erythrocyte sedimentation rate predicted inflammation detected on MRI (r = 0.44, P = 0.014). CONCLUSIONS: The association between the clinician's assessment, core outcome variables and MRI findings in this study was limited. This indicates that clinical and laboratory findings are inadequate diagnostic tools for the assessment of hip arthritis when compared with MRI as the gold standard.

Historical reflections on the afterhyperpolarization--firing rate relation of vertebrate spinal neurons.

In mammalian spinal motoneurons (MNs), the slow component of the afterhyperpolarization (AHP) that follows the spike of each action potential is a major but not the sole determinant of the cells' firing rate. In this brief historical review, we emphasize four points about the AHP-firing rate relation. (1) There is a relatively sparse literature across vertebrates that directly addresses this topic. (2) After the advent of intracellular recording in the early 1950s, there was evidence from mammals to the contrary of an idea that subsequently became prevalent: that the high-firing rates attainable by spinal interneurons (INs) and low-threshold MNs was attributable to their small AHP at rheobase. (3) Further work is needed to determine whether our present findings on the AHP-firing rate relation of turtle cells generalize to the spinal neurons of other vertebrate species. (4) Relevant to point 3, substantial in vivo and in vitro work is potentially available in raw data used in reports on several mammalian and non-mammalian vertebrates. In summary, the factors in addition to the slow AHP that help determine spinal INs and MN firing rate deserve further evaluation across vertebrates, with relevant data already potentially available in several laboratories.

Growing up and moving on in rheumatology: parents as proxies of adolescents with juvenile idiopathic arthritis.

OBJECTIVE: To examine agreement about physical health, functional ability, and health-related quality of life (HRQOL) between adolescents with juvenile idiopathic arthritis (JIA) and their parents. METHODS: The study group comprised 303 adolescent-parent dyads who completed individual questionnaires, including the Childhood Health Assessment Questionnaire with visual analog scales for pain and general well-being, and the Juvenile Arthritis Quality of Life Questionnaire. Agreement was determined using the Bland and Altman method. RESULTS: Approximately half of the adolescent-parent dyads showed clinically acceptable agreement for pain, general well-being, functional disability, and HRQOL. Where discrepancies occurred, there were similar numbers of parental overestimation and underestimation, with the exception that parents rated functional ability worse than did adolescents. Parents were also consistent with respect to overestimation or underestimation, irrespective of the health domain in question. Agreement was associated with better disease-related outcome variables, but was not significantly influenced by demographic factors. Agreement between adolescents and parents was dependent on the level of disease outcome and the health domain under scrutiny, and was less for moderate disease outcomes (as compared with mild or severe) and less visible phenomena (e.g., pain, global well-being). CONCLUSION: There is a wide variation in agreement between adolescents with JIA and their parents that is dependent on which health-related variable is under scrutiny. Proxy report is likely to be valid for adolescents with JIA at either the mild or severe end of the spectrum and/or for the visible manifestations of the disease. Consideration of both adolescent and parent-proxy reports is therefore important in future research.

Health-related quality of life in adolescents with juvenile idiopathic arthritis.

OBJECTIVE: To describe the health-related quality of life (HRQOL) of adolescents with juvenile idiopathic arthritis (JIA), and to examine the usefulness of the Juvenile Arthritis Quality of Life Questionnaire (JAQQ) in a UK context. It was hypothesized that HRQOL would decrease with worsening disease and disability. METHODS: Patients with JIA ages 11, 14, and 17 years were recruited from 10 major rheumatology centers. HRQOL was measured using the JAQQ. Other data were core outcome variables including the Childhood Health Assessment Questionnaire, demographic characteristics, arthritis-related knowledge, and satisfaction with health care. RESULTS: Questionnaires were completed by 308 adolescents. One-fifth had persistent oligoarthritis. Median disease duration was 5.7 years (range <1-16 years). The JAQQ was shown to have good psychometric properties when used in the UK, but was not without limitations. HRQOL of adolescents with JIA was less than optimal, particularly in the domains of gross motor and systemic functioning. Items most frequently rated as adolescents' biggest psychological problems were "felt frustrated" and "felt depressed," rated by 30.2% and 23.4%, respectively. These were particularly problematic for the 17-year-olds, with 39% reporting frustration as one of their biggest problems and 63.6% reporting depression. Variation in the adolescent JAQQ scores was explained by functional disability, pain, and disease activity. CONCLUSION: JIA can have a significant adverse effect on the HRQOL of adolescents. The JAQQ is a useful tool to assess the HRQOL of UK adolescents with JIA, but there is need for improved measures that incorporate developmentally appropriate issues.
