Bayesian Optimization of Environmentally Sustainable Graphene Inks Produced by Wet Jet Milling.

Liquid phase exfoliation (LPE) of graphene is a potentially scalable method to produce conductive graphene inks for printed electronic applications. Among LPE methods, wet jet milling (WJM) is an emerging approach that uses high-speed, turbulent flow to exfoliate graphene nanoplatelets from graphite in a continuous flow manner. Unlike prior WJM work based on toxic, high-boiling-point solvents such as n-methyl-2-pyrollidone (NMP), this study uses the environmentally friendly solvent ethanol and the polymer stabilizer ethyl cellulose (EC). Bayesian optimization and iterative batch sampling are employed to guide the exploration of the experimental phase space (namely, concentrations of graphite and EC in ethanol) in order to identify the Pareto frontier that simultaneously optimizes three performance criteria (graphene yield, conversion rate, and film conductivity). This data-driven strategy identifies vastly different optimal WJM conditions compared to literature precedent, including an optimal loading of 15 wt% graphite in ethanol compared to 1 wt% graphite in NMP. These WJM conditions provide superlative graphene production rates of 3.2 g hr-1 with the resulting graphene nanoplatelets being suitable for screen-printed micro-supercapacitors. Finally, life cycle assessment reveals that ethanol-based WJM graphene exfoliation presents distinct environmental sustainability advantages for greenhouse gas emissions, fossil fuel consumption, and toxicity.

Cognitive testing of the Children's Palliative Outcome Scale (C-POS) with children, young people and their parents/carers.

BACKGROUND: The Children's Palliative Outcome Scale (C-POS) is being developed using best methodological guidance on outcome measure development, This recommends cognitive testing, an established method of item improvement, prior to psychometric testing. AIM: To cognitively test C-POS within the target population to establish comprehensibility, comprehensiveness, relevance and acceptability. DESIGN: Cross-sectional cognitive interview study following COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology and Rothrock guidance on outcome measure development. Cognitive interviews were conducted using 'think aloud' and verbal probing techniques. SETTING/PARTICIPANTS: Children 5-⩽17 years old with life-limiting conditions and parents/carers of children with life-limiting conditions were recruited from 14 UK sites. RESULTS: Forty-eight individuals participated (36 parents; 12 children) in cognitively testing the five versions of C-POS over two to seven rounds. Content and length were acceptable, and all questions were considered important. Refinements were made to parent/carer versions to be inclusive of non-verbal children such as changing 'share' to 'express' feelings; and 'being able to ask questions' to 'having the appropriate information'. Changes to improve comprehensibility of items such as 'living life to the fullest' were also made. Parents reported that completing an outcome measure can be distressing but this is anticipated and that being asked is important. CONCLUSION: Cognitive interviewing has facilitated refinement of the C-POS, especially for non-verbal children who represent a large proportion of those with a life-limiting condition. This study has enhanced the face and content validity of the measure and provided preliminary evidence for acceptability for use in routine practice.

What are the anticipated benefits, risks, barriers and facilitators to implementing person-centred outcome measures into routine care for children and young people with life-limiting and life-threatening conditions? A qualitative interview study with key stakeholders.

BACKGROUND: There is a growing evidence-base underpinning implementation of person-centred outcome measures into adult palliative care. However evidence on how best to achieve this with children facing life-threatening and life-limiting conditions is limited. AIM: To identify the anticipated benefits, risks, barriers and facilitators to implementing person-centred outcome measures for children with life-limiting and life-threatening conditions. DESIGN: Cross-sectional qualitative semi-structured interview study with key stakeholders analysed using Framework analysis informed by the adapted-Consolidated Framework for Implementation Research. SETTING/PARTICIPANTS: A total of n = 26 children with life-limiting or life-threatening conditions, n = 40 parents/carers, n = 13 siblings and n = 15 health and social care professionals recruited from six hospitals and three children's hospices and n = 12 Commissioners of health services. RESULTS: All participants were supportive of future implementation of person-centred outcome measures into care. Anticipated benefits included: better understanding of patient and family priorities, improved communication and collaborative working between professionals and families and standardisation in data collection and reporting. Anticipated risks included increased workload for staff and measures not being used as intended. Implementation barriers included: acceptability and usability of outcome measures by children; burden and capacity of parents/carers regarding completion; privacy concerns; and language barriers. Implementation facilitators included designing measures using language that is meaningful to children and families, ensuring potential benefits of person-centred outcome measures are communicated to encourage 'buy-in' and administering measures with known and trusted professional. CONCLUSIONS: Implementation of person-centred outcome measures offer potential benefits for children with life-limiting and life-threatening conditions. Eight recommendations are made to maximise benefits and minimise risks in implementation.

'My life is a mess but I cope': An analysis of the language children and young people use to describe their own life-limiting or life-threatening condition.

BACKGROUND: Children and young people with life-limiting and life-threatening conditions have multidimensional needs and heterogenous cognitive and communicative abilities. There is limited evidence to support clinicians to tailor their communication to each individual child. AIM: To explore the language children and young people use to describe their own condition, to inform strategies for discussing needs and priorities. DESIGN: Positioned within a social constructivist paradigm, a secondary discourse analysis of semi-structured interview data was conducted incorporating the discourse dynamics approach for figurative language. SETTING/PARTICIPANTS: A total of 26 children and young people aged 5-17 years with life-limiting or life-threatening conditions (6 cancer; 20 non-cancer) were recruited from nine clinical services (six hospitals and three hospices) across two UK nations. RESULTS: The language children and young people use positions them as 'experts in their condition'. They combine medical terminology with their preferred terms for their body to describe symptoms and treatments, and use comparatives and superlatives to communicate their health status. Their language depicts their condition as a 'series of (functional and social) losses', which single them out from their peers as 'the sick one'. Older children and young people also incorporate figurative language to expand their descriptions. CONCLUSION/DISCUSSION: Children and young people can provide rich descriptions of their condition. Paying attention to their lexical choices, and converging one's language towards theirs, may enable more child-centred discussions. Expanding discussions about 'what matters most' with consideration of the losses and differences they have experienced may facilitate a fuller assessment of their concerns, preferences and priorities.

Children's understanding of dying and death: A multinational grounded theory study.

OBJECTIVES: The ways in which children understand dying and death remain poorly understood; most studies have been carried out with samples other than persons with an illness. The objective of this study was to understand the process by which children directly involved with life-limiting conditions understand dying and death. METHODS: This qualitative study obtained interview data from N = 44 5-18-year-old children in the USA, Haiti, and Uganda who were pediatric palliative care patients or siblings of patients. Of these, 32 were children with a serious condition and 12 were siblings of a child with a serious condition. Interviews were recorded, transcribed, verified, and analyzed using grounded theory methodology. RESULTS: Loss of normalcy and of relationships emerged as central themes described by both ill children and siblings. Resilience, altruism, and spirituality had a bidirectional relationship with loss, being strategies to manage both losses and anticipated death, but also being affected by losses. Resiliency and spirituality, but not altruism, had a bidirectional relationship with anticipating death. Themes were consistent across the 3 samples, although the beliefs and behaviors expressing them varied by country. SIGNIFICANCE OF RESULTS: This study partially fills an identified gap in research knowledge about ways in which children in 3 nations understand dying and death. While children often lack an adult vocabulary to express thoughts about dying and death, results show that they are thinking about these topics. A proactive approach to address issues is warranted, and the data identify themes of concern to children.

Spiritual, religious, and existential concerns of children and young people with life-limiting and life-threatening conditions: A qualitative interview study.

BACKGROUND: Despite being a core domain of palliative care, primary data on spiritual and existential concerns has rarely been collected among children with life-limiting and life-threatening conditions and their families. Existing evidence has tended to focus on the religious aspects among children with cancer. AIM: To identify the spiritual needs of children with life-limiting and life-threatening conditions. DESIGN: Cross-sectional semi-structured, qualitative interview study with children, families and health and social care professionals. Verbatim transcripts were analysed using Framework analysis. SETTING/PARTICIPANTS: Purposively sampled children with life-limiting and life-threatening conditions, their parents and siblings, health and social care professionals recruited from six hospitals and three children's hospices in the UK, and commissioners of paediatric palliative care services recruited through networks and a national charity. RESULTS: One hundred six participants were interviewed: 26 children (5-17 years), 53 family members (parents/carers of children 0-17 years and siblings (5-17 years)), 27 professionals (health and social care professionals and commissioners of paediatric palliative care). Themes included: living life to the fullest, meaning of life and leaving a legacy, uncertainty about the future, determination to survive, accepting or fighting the future and role of religion. Children as young as 5 years old identified needs or concerns in the spiritual domain of care. CONCLUSIONS: Addressing spiritual concerns is essential to providing child- and family-centred palliative care. Eliciting spiritual concerns may enable health and social care professionals to identify the things that can support and enhance a meaningful life and legacy for children and their families.

Achieving consensus on priority items for paediatric palliative care outcome measurement: Results from a modified Delphi survey, engagement with a children's research involvement group and expert item generation.

BACKGROUND: There is no validated outcome measure for use in children's palliative care outside sub-Saharan Africa. Stakeholders must be involved in the development of such measures to ensure face and content validity. AIM: To gain expert stakeholder consensus on items for inclusion in a paediatric palliative care outcome measure to establish face and content validity. DESIGN: This study was conducted in two phases following Rothrock and COSMIN guidance on patient-reported outcome measure development. Phase 1: Three-round modified Delphi survey to establish consensus on priority items. Phase 2: Item generation meeting with key stakeholders to develop initial measure versions. A young person's advisory group was also consulted on priority outcomes. SETTING AND PARTICIPANTS: Delphi survey: Parents and professionals with experience of caring for a child with a life-limiting condition. Young person's advisory group: young people age 10-20 years. Item generation meeting: bereaved parents, academics and clinicians. RESULTS: Phase 1: Delphi survey (n = 82). Agreement increased from Kendall's W = 0.17 to W = 0.61, indicating movement towards consensus. Agreement between professional and parent ranking was poor (Cohen's kappa 0.13). Professionals prioritised physical symptoms, whereas parents prioritised psychosocial and practical concerns. Advisory group: Children (n = 22) prioritised items related to living a 'normal life' in addition to items prioritised by adult participants. Phase 2: Five age/developmental stage appropriate child and proxy-reported versions of C-POS, containing 13 items, were drafted. CONCLUSIONS: This study highlights the importance and feasibility of involving key stakeholders in PROM item generation, as important differences were found in the priority outcomes identified by children, parents and professionals.

Current status of African pediatric oncology education efforts aligned with the Global Initiative for Childhood Cancer.

Education of the pediatric oncology workforce is an important pillar of the World Health Organization CureAll technical package. This is not only limited to healthcare workers, but all stakeholders in the childhood cancer management process. It includes governmental structures, academic institutions, parents and communities. This review evaluated the current educational and advocacy training resources available to the childhood cancer community, the contribution of SIOP Africa in the continental educational needs and evaluated future needs to improve the management of pediatric malignancies in reaching the Global Initiative for Childhood Cancer goals. Childhood cancer, unlike adult cancers, has not been prioritized in African cancer control plans nor the teaching and advocacy surrounding pediatric oncology. The availability of formal training programs for pediatric oncologists, pediatric surgeons and radiotherapy specialists are limited to particular countries. In pharmacy and nutritional services, the exposure to pediatric oncology is limited while training in advocacy doesn't exist. Many nonacademic stakeholders are creating the opportunities in Africa to gain experience and train in these various fields, but formal training programs should still be advocated for. LEARNING POINTSThe African continent has various resources to increase the capacity of childhood cancer care stakeholders to increase their knowledge.African pediatric oncology teams rely on a multitude of international sources for training while developing their own.There is a greater need for formal, standardized cancer training especially for pediatric surgeons, radio-oncologists and nurses.Greater inclusion of pathologists, pediatric oncology pharmacists and dieticians into multidisciplinary care and childhood cancer training should be facilitated and resourced.Successful advocacy programs and tool kits exist in parts of Africa, but the training in advocacy is still underdeveloped.

Parents' experiences of initiation of paediatric advance care planning discussions: a qualitative study.

Advance care planning enables parents to discuss their goal and wishes for the future treatment and care of their life-limited or life-threatened child. Whilst research has identified the barriers clinicians face to initiate such discussions, the views of the parents have received scant attention. This qualitative study, using reflexive thematic analysis, aimed to explore parents' experience of the initiation of their child's advance care planning discussions, to help provide an understanding to inform future practice. Single interviews were undertaken with 17 non-bereaved and bereaved parents. Parents reported they had engaged with future thinking but needed time before initiating this with clinicians. They identified the need for a trusted professional and time for private, thorough, non-judgemental discussion without feeling clinicians were 'giving up'. Parents reported that advance care planning discussions were not always aligned to the dynamics of family life. They felt that health professionals were responsible for initiating advance planning conversations according to the families' individual requirements. There was an apparent lack of standardised protocols to assist paediatric advance care planning discussion initiation.Conclusion: Initiating advance care planning is a complicated process that needs to be tailored to the specific parent and child situation. Health professionals need to appreciate that parents are key contributors to initiate engagement with advance care planning discussions but that they also require support and care, recognising this may facilitate the building of trust, identified as a key corner stone, of paediatric advance care planning initiation and engagement. What is Known: • In paediatric palliative care, parents are challenged with wanting to sustain hope whilst thinking and planning for their child's end of life. Paediatric advance care planning discussions are often delayed or avoided and triggered by physical deterioration. What is New: • Previous relationship with HCP not essential but parental trust of the HCP is fundamental to Paediatric advance care planning initiation engagement. To build mutual trust health professionals' approach needs to be professional, respectful and empathetic to the parent and child's situation. • Subtle paediatric advance care planning parent initiation preparation by HCP is often unnoticed by parents but may be the crux of empowering parents to initiate advance care planning conversations themselves as they need to feel a sense of regaining control before planning ahead.

Achieving child-centred care for children and young people with life-limiting and life-threatening conditions-a qualitative interview study.

This study aims to identify the symptoms, concerns, and care priorities of children with life-limiting conditions and their families. A semi-structured qualitative interview study was conducted, seeking perspectives from multiple stakeholders on symptoms, other concerns, and care priorities of children and young people with life limiting and life-threatening conditions and their families. Participants were recruited from six hospitals and three children's hospices in the UK. Verbatim transcripts were analysed using framework analysis. A total of 106 participants were recruited: 26 children (5-17 years), 40 parents (of children 0-17 years), 13 siblings (5-17 years), 15 health and social care professionals, 12 commissioners. Participants described many inter-related symptoms, concerns, and care priorities impacting on all aspects of life. Burdensome symptoms included pain and seizures. Participants spoke of the emotional and social impacts of living with life-limiting conditions, such as being able to see friends, and accessing education and psychological support. Spiritual/existential concerns included the meaning of illness and planning for an uncertain future. Data revealed an overarching theme of pursuing 'normality', described as children's desire to undertake usual childhood activities. Parents need support with practical aspects of care to help realise this desire for normality. CONCLUSION: Children with life-limiting conditions and their families experience a wide range of inter-related symptoms, concerns, and care priorities. A holistic, child-centred approach to care is needed, allowing focus on pursuit of normal childhood activities. Improvements in accessibility, co-ordination, and availability of health services are required to achieve this. WHAT IS KNOWN: • Existing evidence regarding symptoms, concerns, and care priorities for children with life-limiting conditions is largely limited to proxy-reported data and those with a cancer diagnosis. • Child-centred care provision must be directed by children's perspectives on their priorities for care. WHAT IS NEW: • Social and educational activities are more important to children with life-limiting conditions than their medical concerns. • A holistic approach to care is required that extends beyond addressing medical needs, in order to support children with life-limiting conditions to focus on pursuit of normal childhood activities.

Face and content validity, acceptability, feasibility, and implementability of a novel outcome measure for children with life-limiting or life-threatening illness in three sub-Saharan African countries.

BACKGROUND: The Children's Palliative Care Outcome Scale (C-POS) is the first measure developed for children with life-limiting and -threatening illness. It is essential to determine whether the measure addresses what matters to children, and if they can comprehend and respond to its items. AIM: To determine the face and content validity, comprehensiveness, comprehensibility, acceptability and feasibility, and implementability of the C-POS. DESIGN: Mixed methods (1) Content validation: mapping C-POS items onto an evidence-based framework from prior evidence; (2) Comprehensiveness, comprehensibility, acceptability feasibility, and implementability: qualitative in-depth and cognitive interviews with a purposive sample of children and young people (n = 6), family caregivers (n = 16), and health workers (n = 12) recruited from tertiary facilities in Kenya, South Africa, and Uganda. RESULTS: (1) C-POS content mapped on to palliative care domains for (a) children (i.e. physical (e.g. symptoms), social (e.g. play/socialize), psychological (e.g. happy)) and (b) families (i.e. psychological (e.g. worry), social (e.g. information), and help and advice). (2) C-POS items were well understood by children and their caregivers, acceptable, and relevant. Completion time was a median of 10 min, patients/caregivers and health workers reported that using the C-POS improved their communication with children and young people. Methodological and content issues included: (i) conceptual gap in the spiritual/existential domain; (ii) further consideration of developmental, age-appropriate items in the social and psychological domains, and (iii) linguistic complexity and difficulty in proxy rating. CONCLUSION: C-POS items capture the core symptoms and concerns that matter to children and their families. C-POS is feasible, comprehensible, and acceptable for use in clinical settings; areas for further development and improvement are identified.

Morphology and electrical properties of high-speed flexography-printed graphene.

Printed graphene electrodes have been demonstrated as a versatile platform for electrochemical sensing, with numerous examples of rapid sensor prototyping using laboratory-scale printing techniques such as inkjet and aerosol jet printing. To leverage these materials in a scalable production framework, higher-throughput printing methods are required with complementary advances in ink formulation. Flexography printing couples the attractive benefits of liquid-phase graphene printing with large-scale manufacturing. Here, we investigate graphene flexography for the fabrication of electrodes by analyzing the impacts of ink and process parameters on print quality and electrical properties. Characterization of the printed patterns reveals anisotropic structure due to striations along the print direction, which is related to viscous fingering of the ink. However, high-resolution imaging reveals a dense graphene network even in regions of sparse coverage, contributing to robust electrical properties even for the thinnest films (< 100 nm). Moreover, the mechanical and environmental sensitivity of the printed electrodes is characterized, with particular focus on atmospheric response and thermal hysteresis. Overall, this work reveals the conditions under which graphene inks can be employed for high-speed flexographic printing, which will facilitate the development of graphene-based sensors and related devices.

Initiation of paediatric advance care planning: Cross-sectional survey of health professionals reported behaviour.

BACKGROUND: Globally, initiation of paediatric advance care planning discussions is advocated early in the illness trajectory; however, evidence suggests it occurs at crisis points or close to end of life. Few studies have been undertaken to ascertain the prevalence and determinants of behaviour related to initiation by the healthcare professional. METHOD: Underpinned by the Capability, Opportunity, Motivation-Behaviour (COM-B) model for behaviour change, a cross-sectional online survey was conducted in United Kingdom and Ireland using a purposive sample of health professionals. Descriptive and inferential statistics were applied and nonparametric statistical analysis used. Open-ended questions were mapped and correlations between COM-B and demographic profiles identified. RESULTS: Responses (n = 140): Paediatric advance care planning was viewed positively; however, initiation practices were found to be influenced by wide ranging diagnoses and disease trajectories. Whilst some tools and protocols exist, they were not used in a systematic manner, and initiation behaviour was often not guided by them. Initiation was unstandardized, individually led, guided by intuition and experience and based on a range of prerequisites. Such behaviour, combined with inconsistencies in professional development, resulted in varying practice when managing clinical deterioration. Professionals who felt adequately trained initiated more conversations (capability). Those working in palliative care specialties, hospice settings and doctors initiated more discussions (opportunity). There was no difference in Motivation between professions, clinical settings or specialisms, although 25% (n = 35) of responses indicated discomfort discussing death and 34% (n = 49) worried about families' emotional reaction. CONCLUSION: Although advocated, paediatric advance care planning is a complex process, commonly triggered by the physical deterioration and rarely underpinned by support tools. The COM-B framework was useful in identifying fundamental differences in initiation behaviour; however, further research is required to explore the complexity of initiation behaviour and the system within which the care is being delivered to identify influences on initiation.

'Whose life are They Going to Save? It's Probably Not Going to be Mine!' Living With a Life-Shortening Condition During the Coronavirus (COVID-19) Pandemic: A Grounded Theory Study of Embodied Precarity.

This article explores the experiences of young adults with a life-shortening condition in the first wave of the Coronavirus (COVID-19) pandemic in the UK. It presents the findings from an inclusive qualitative research study using constructivist grounded theory which aimed to examine the unintended consequences of pandemic control measures (lockdown and 'shielding') on this population. Purposive and theoretical sampling methods were used to recruit young adults with a life-shortening condition, employing a range of recruitment methods such as social media, advertising in newsletters and snowballing. Twenty-six young adults (aged 22-40 years), with a wide range of life-shortening conditions participated in the study. Seventeen participants were female and nine male. The majority identified as White British/Other and the remainder as Black British (2), Mixed Race (2) or Latin American (1). Data were generated iteratively using in-depth guided interviews and analysed collectively by an inclusive research team using the constant comparative method. The article explores a theory of embodied precariousness of living with a life-shortening condition during the first wave of the Coronavirus pandemic in relation to three categories: the rationing of life-saving treatment, the deterioration of health and retraction of healthcare provision, and the disruption of typical care arrangements. The findings show that the pandemic control measures introduced to keep people safe have intensified the precarity of this group promoting inequalities in healthcare and health outcomes. The article identifies some implications for practice to support the future management of unexpected and unwanted change.

Dissolution of 2D Molybdenum Disulfide Generates Differential Toxicity among Liver Cell Types Compared to Non-Toxic 2D Boron Nitride Effects.

2D boron nitride (BN) and molybdenum disulfide (MoS2 ) materials are increasingly being used for applications due to novel chemical, electronic, and optical properties. Although generally considered biocompatible, recent data have shown that BN and MoS2 could potentially be hazardous under some biological conditions, for example, during, biodistribution of drug carriers or imaging agents to the liver. However, the effects of these 2D materials on liver cells such as Kupffer cells (KCs), liver sinusoidal endothelial cells, and hepatocytes, are unknown. Here, the toxicity of BN and MoS2 , dispersed in Pluronic F87 (designated BN-PF and MoS2 -PF) is compared with aggregated forms of these materials (BN-Agg and MoS2 -Agg) in liver cells. MoS2 induces dose-dependent cytotoxicity in KCs, but not other cell types, while the BN derivatives are non-toxic. The effect of MoS2 could be ascribed to nanosheet dissolution and the release of hexavalent Mo, capable of inducing mitochondrial reactive oxygen species generation and caspases 3/7-mediated apoptosis in KUP5 cells. In addition, the phagocytosis of MoS2 -Agg triggers an independent response pathway involving lysosomal damage, NLRP3 inflammasome activation, caspase-1 activation, IL-1ß, and IL-18 production. These findings demonstrate the importance of Mo release and the state of dispersion of MoS2 in impacting KC viability.

Printable hexagonal boron nitride ionogels.

Due to its excellent chemical/thermal stability and mechanical robustness, hexagonal boron nitride (hBN) is a promising solid matrix material for ionogels. While bulk hBN ionogels have been employed in macroscopic applications such as lithium-ion batteries, hBN ionogel inks that are compatible with high-resolution printing have not yet been realized. Here, we describe aerosol jet-printable ionogels using exfoliated hBN nanoplatelets as the solid matrix. The hBN nanoplatelets are produced from bulk hBN powders by liquid-phase exfoliation, allowing printable hBN ionogel inks to be formulated following the addition of an imidazolium ionic liquid and ethyl lactate. The resulting inks are reliably printed with variable patterns and controllable thicknesses by aerosol jet printing, resulting in hBN ionogels that possess high room-temperature ionic conductivities and storage moduli of >3 mS cm-1 and >1 MPa, respectively. By integrating the hBN ionogel with printed semiconductors and electrical contacts, fully-printed thin-film transistors with operating voltages below 1 V are demonstrated on polyimide films. These devices exhibit desirable electrical performance and robust mechanical tolerance against repeated bending cycles, thus confirming the suitability of hBN ionogels for printed and flexible electronics.

Factors associated with health professionals decision to initiate paediatric advance care planning: A systematic integrative review.

BACKGROUND: Advance care planning for children with palliative care needs is an emotionally, legally and complex aspect of care, advocated as beneficial to children, families and health professionals. Evidence suggests healthcare professionals often avoid or delay initiation. An overview of evidence on the factors that influence and impact on the health care professional's initiation of paediatric advance care planning process is lacking. AIM: To review and synthesise evidence on the factors associated with health care professional's decision to initiate paediatric advance care planning. DESIGN: Systematic integrative review using constant comparison method. DATA SOURCES: Electronic databases (CINAHL, PubMed, PsycINFO, Ovid MEDLINE, EMBASE, Web of Science and Cochrane) using MeSH terms and word searches in Oct 2019. No limit set on year of publication or country. Grey literature searches were also completed. RESULTS: The search yielded 4153 citations from which 90 full text articles were reviewed. Twenty-one met inclusion criteria consisting of quantitative (n = 8), qualitative (n = 6) and theoretical (n = 7) studies.Findings revealed overarching and interrelated themes 'The timing of initiation', 'What makes an initiator, 'Professionals' perceptions' and 'Prerequisites to initiation'. CONCLUSIONS: This review provides insights into the complexities and factors surrounding the initiation of advance care planning in paediatric practice. Uncertainty regarding prognosis, responsibility and unpredictable parental reactions result in inconsistent practice. Future research is required to inform intervention to assist health care professionals when initiating paediatric advance care planning conversations.

Children's palliative care education and training: developing an education standard framework and audit.

BACKGROUND: The need to align the range of guidance and competencies concerning children's palliative care and develop an education framework have been recommended by a UK All-Party Parliament Group and others. In response to these recommendations the need for a revised children's palliative care competency framework was recognized. A Children's Palliative Care Education and Training Action Group, comprising champions in the field, was formed across UK and Ireland in 2019 to take this work forward. Their aim was to agree core principles of practice in order to standardize children's palliative care education and training. METHODS: Over four meetings the Action Group reviewed sources of evidence and guidance including palliative care competency documents and UK and Ireland quality and qualification frameworks. Expected levels of developing knowledge and skills were then agreed and identified competencies mapped to each level. The mapping process led to the development of learning outcomes, local indicative programme content and assessment exemplars. RESULTS: Four sections depicting developing levels of knowledge and skills were identified: Public Health, Universal, Core, Specialist. Each level has four learning outcomes: Communicating effectively, Working with others in and across various settings, Identifying and managing symptoms, Sustaining self-care and supporting the well-being of others. An audit tool template was developed to facilitate quality assurance of programme delivery. The framework and audit tool repository is on the International Children's Palliative Care Network website for ease of international access. CONCLUSIONS: The framework has received interest at UK, Ireland and International launches. While there are education programmes in children's palliative care this is the first international attempt to coordinate education, to address lay carer education and to include public health.

Towards person-centred quality care for children with life-limiting and life-threatening illness: Self-reported symptoms, concerns and priority outcomes from a multi-country qualitative study.

BACKGROUND: Paediatric life-limiting and life-threatening conditions (life-limiting conditions) place significant strain on children, families and health systems. Given high service use among this population, it is essential that care addresses their main symptoms and concerns. AIM: This study aimed to identify the symptoms, concerns and other outcomes that matter to children with life-limiting conditions and their families in sub-Saharan Africa. SETTING AND PARTICIPANTS: Cross-sectional qualitative study in Kenya, Namibia, South Africa and Uganda. Children/caregivers of children aged 0-17 years with life-limiting conditions were purposively sampled by age, sex and diagnosis. Children aged 7 and above self-reported; caregiver proxies reported for children below 7 and those aged 7 and above unable to self-report. RESULTS: A total of 120 interviews were conducted with children with life-limiting conditions (n = 61; age range: 7-17 years), and where self-report was not possible, caregivers (n = 59) of children (age range: 0-17) were included. Conditions included advanced HIV (22%), cancer (19%), heart disease (16%) endocrine, blood and immune disorders (13%), neurological conditions (12%), sickle cell anaemia (10%) and renal disease (8%). Outcomes identified included physical concerns - pain and symptom distress; psycho-social concerns - family and social relationships, ability to engage with age-appropriate activities (e.g. play, school attendance); existential concerns - worry about death, and loss of ambitions; health care quality - child- and adolescent-friendly services. Priority psycho-social concerns and health service factors varied by age. CONCLUSION: This study bridges an important knowledge gap regarding symptoms, concerns and outcomes that matter to children living with life-limiting conditions and their families and informs service development and evaluation.
