Gabapentin for Pain in Pediatric Palliative Care.

OBJECTIVE: Gabapentin is commonly used to treat pain in children receiving pediatric palliative care. This study describes the real-world use of gabapentin and the associated benefits and adverse effects/events (AEs). METHODS: A prospective, multicenter cohort of standardized data collection after a clinical decision was made to use gabapentin for managing neuropathic or nociplastic pain in children attended on by a pediatric palliative care service. It was conducted across 11 sites in seven countries including hospital, inpatient, and outpatient services. Clinical outcomes were graded using pain scales validated for age and cognitive ability and the National Cancer Institute Common Terminology Criteria for Adverse Events (NCICTCAE) at baseline, 14 days, 28 days, six weeks and 12 weeks after initiation of gabapentin. Ad-hoc safety reporting continued throughout the study. RESULTS: Data were collected from 127 children with a median age of 4.7 years (IQR 0.1-17.9); 61% had a neurological disorder, 21% advanced cancer and the cohort had a high level of disability (Lansky/Karnofsky performance score 37.1). Gabapentin was prescribed at standard pediatric doses. On average, 76% of children had a reduction in pain and 42% experienced a potential AE. The mean pain score decreased from 6.0 (SD 2.6) at baseline to 3.3 (SD 2.4) at 14 days and 1.8 (SD 1.8) after 12-weeks of gabapentin therapy. Ten percent had increased pain at each time point. AEs did not increase when individual changes over time were accounted for except for somnolence (7%). Serious AEs attributable to gabapentin were possible or probable in 3% of children. CONCLUSIONS: Gabapentin prescribed at standard doses for advanced cancer and severe neurological injury in children under a pediatric palliative care service was associated with generally improved pain intensity at previously described levels of adverse effects.

Questions directed to children with diverse communicative competencies in paediatric healthcare consultations.

OBJECTIVE: This paper examines question-response sequences, in which clinicians asked questions to child patients who appear to interact using means other than the verbal mode of communication. METHODS: Conversation Analysis methods were used to study questions in 46 paediatric palliative care consultations. These questions were directed towards children who observably used vocalisations and embodied modes of communication (e.g., gaze, gesture and facial expressions) but did not appear to use the verbal mode. RESULTS: Most questions asked children either about their willingness and preferences for a proposed next activity, or their current feelings, experiences or intentions. Questions involved children by foregrounding their preferences and feelings. These questions occasioned contexts where the child's vocal or embodied conduct could be treated as a relevant response. CONCLUSION: This paper demonstrates how questions are used to involve children in consultations about their own healthcare, and how their views come to be understood by clinicians and family members, even when children interact using means other than the verbal mode of communication. PRACTICE IMPLICATIONS: Questions can be asked of both children who do and do not verbally communicate. When asking questions, clinicians should be mindful of the modes of communication an individual child uses to consider how the child might meaningfully respond.

Cost-effectiveness of decellularised bone allograft compared with fresh-frozen bone allograft for acetabular impaction bone grafting during a revision hip arthroplasty in the UK.

OBJECTIVES: Fresh-frozen allograft is the gold-standard bone graft material used during revision hip arthroplasty. However, new technology has been developed to manufacture decellularised bone with potentially better graft incorporation. As these grafts cost more to manufacture, the aim of this cost-effectiveness study was to estimate whether the potential health benefit of decellularised bone allograft outweighs their increased cost. STUDY DESIGN: A Markov model was constructed to estimate the costs and the quality-adjusted life years of impaction bone grafting during a revision hip arthroplasty. SETTING: This study took the perspective of the National Health Service in the UK. PARTICIPANTS: The Markov model includes patients undergoing a revision hip arthroplasty in the UK. INTERVENTION: Impaction bone grafting during a revision hip arthroplasty using either decellularised bone allograft or fresh-frozen allograft. MEASURES: Outcome measures included: total costs and quality-adjusted life years of both interventions over the lifetime of the model; and incremental cost-effectiveness ratios for both graft types, using base case parameters, univariate sensitivity analysis and probabilistic analysis. RESULTS: The incremental cost-effectiveness ratio for the base case model was found to be £270 059 per quality-adjusted life year. Univariate sensitivity analysis found that changing the discount rate, the decellularised bone graft cost, age of the patient cohort and the revision rate all had a significant effect on the incremental cost-effectiveness ratio. CONCLUSIONS: As there are no clinical studies of impaction bone grafting using a decellularised bone allograft, there is a high level of uncertainty around the costs of producing a decellularised bone allograft and the potential health benefits. However, if a decellularised bone graft was manufactured for £2887 and lowered the re-revision rate to less than 64 cases per year per 10 000 revision patients, then it would most likely be cost-effective compared with fresh-frozen allograft.

Cannabinoids for symptom management in children with cancer: A systematic review and meta-analysis.

BACKGROUND: Despite the widespread use of medical cannabis, little is known regarding the safety, efficacy, and dosing of cannabis products in children with cancer. The objective of this study was to systematically appraise the existing published literature for the use of cannabis products in children with cancer. METHODS: This systematic review, registered with the International Prospective Register of Systematic Reviews (CRD42020187433), searched four databases: MEDLINE, Embase, PsycINFO, and the Cochrane Library. Abstracts and full texts were screened in duplicate. Data on types of cannabis products, doses, formulations, frequencies, routes of administration, indications, and clinical and demographic details as well as reported efficacy outcomes were extracted. Data on cannabinoid-related adverse events were also summarized. RESULTS: Out of 34,611 identified citations, 19 unique studies with a total of 1927 participants with cancer were included: eight retrospective chart reviews, seven randomized controlled trials, two open-label studies, and two case reports. The included studies reported the use of various cannabis products for the management of symptoms. Cannabinoids were commonly used for the management of chemotherapy-induced nausea and vomiting (11 of 19 [58%]). In controlled studies, somnolence, dizziness, dry mouth, and withdrawal due to adverse events were more commonly associated with the use of cannabinoids. Across all included studies, no serious cannabis-related adverse events were reported. CONCLUSIONS: Although there is evidence to support the use of cannabis for symptom management, in children with cancer, there is a lack of rigorous evidence to inform the dosing, safety, and efficacy of cannabinoids. Because of the increasing interest in using cannabis, there is an urgent need for more research on medical cannabis in children with cancer.

Feasibility of Weekly Electronic Patient- and Proxy-Reported Outcome Measures in Pediatric Oncology.

BACKGROUND: Electronic patient-reported outcome measures (ePROMs) benefit adult cancer care, but their use in pediatric cancer care is limited. OBJECTIVES: To explore the feasibility of collecting weekly ePROMs from pediatric cancer patients and/or their caregivers and to describe children's levels of symptom burden, distress, and cancer-related quality of life. METHODS: A prospective and longitudinal cohort study was undertaken at one tertiary children's cancer center. Children (2-18 years)/caregivers completed ePROMs with validated measures for distress, symptom burden, and cancer-related quality of life weekly for 8 weeks. RESULTS: Seventy children/caregivers participated in the study, and 69% completed ePROMs at all 8 weeks. Distress and cancer-related quality of life significantly improved over time. However, at week 8, almost half of the participants still reported high levels of distress. Symptom burden decreased over time, with the youngest and the oldest age groups (2-3 and 13-18 years) reporting the highest number of symptoms with severe burden. CONCLUSIONS: Weekly collection of ePROMs in pediatric cancer care is feasible. Although distress, quality of life, and symptom burden improve over time, there is a need for timely assessment and interventions to improve symptoms, high levels of distress, and issues that negatively affect quality of life. IMPLICATIONS FOR PRACTICE: Nurses are ideally placed to intervene, assess, and monitor symptoms and to provide symptom management advice to pediatric cancer patients and caregivers. Findings from this study may inform the design of models of pediatric cancer care to improve communication with the healthcare team and patient experience of care.

Mentoring the Wellbeing of Specialist Pediatric Palliative Care Medical and Nursing Trainees: The Quality of Care Collaborative Australia.

Background: The Quality of Care Collaborative Australia (QuoCCA), working across 6 tertiary centers throughout Australia, builds capability in the generalist and specialist pediatric palliative care (PPC) workforce, by providing education in metropolitan and regional areas. As part of the education and mentoring framework, Medical Fellows and Nurse Practitioner Candidates (trainees) were funded by QuoCCA at four tertiary hospitals throughout Australia. Objective: This study explores the perspectives and experiences of clinicians who had occupied the QuoCCA Medical Fellow and Nurse Practitioner trainee positions in the specialised area of PPC at Queensland Children's Hospital, Brisbane, to identify the ways in which they were supported and mentored to maintain their wellbeing and facilitate sustainable practice. Methods: Discovery Interview methodology was used to collect detailed experiences of 11 Medical Fellows and Nurse Practitioner candidates/trainees employed by QuoCCA from 2016 to 2022. Results: The trainees were mentored by their colleagues and team leaders to overcome challenges of learning a new service, getting to know the families and building their competence and confidence in providing care and being on call. Trainees experienced mentorship and role modelling of self-care and team care that promoted wellbeing and sustainable practice. Group supervision provided dedicated time for reflection as a team and development of individual and team wellbeing strategies. The trainees also found it rewarding to support clinicians in other hospitals and regional teams that cared for palliative patients. The trainee roles provided the opportunity to learn a new service and broaden career horizons as well as establish wellbeing practices that could be transferred to other areas. Conclusion: Collegial interdisciplinary mentoring, with the team learning together and caring for each other along common goals, contributed immensely to the wellbeing of the trainees as they developed effective strategies to ensure their sustainability in caring for PPC patients and families.

Education and Mentoring of Specialist Pediatric Palliative Care Medical and Nursing Trainees: The Quality of Care Collaborative Australia.

Background: The Quality of Care Collaborative Australia (QuoCCA) builds capability in the generalist and specialist paediatric palliative care (PPC) workforce throughout Australia. It supports regional and community services to provide care close to families' homes, as well as building expertise in tertiary centers. Objective: Medical Fellows and Nurse Practitioner candidates (specialist trainees) were funded by QuoCCA at four tertiary hospitals throughout Australia supported by an education and mentoring framework. This study explored the activity and experiences of clinicians who had occupied these roles to evaluate their effectiveness to build PPC capability. Methods: Online surveys recorded the monthly activity of Medical Fellows, with a point in time check of knowledge, skills and confidence in 2019. Discovery Interview methodology was used to collect detailed experiences of 11 trainees employed between 2018 to 2022 in Queensland. Results: A combination of mentoring and formal and informal education, peer support and practical experience was valuable for trainees. They found the support of the whole interdisciplinary team advantageous to learning. Shadowing experienced team members gave them the opportunity to learn practical skills, especially regarding communication with families. Practicing clinical skills was beneficial, through being on call, attending home visits, supporting families, prescribing medications and developing treatment plans in collaboration with the team. The trainee experience was optimised through learning from families, personal reflection, involvement in research projects and delivering QuoCCA education. Conclusion: The QuoCCA trainee roles for Medical Fellows and Nurse Practitioner candidates exhibit a valuable and effective education and mentorship framework that could be applied to other specialties. The service leadership and collaborative interdisciplinary team support various modes of education and mentoring. The roles not only develop the trainees' specialised PPC clinical skills, they also improve their general clinical practice, including communication, empathy and holistic care. A structured curriculum of education is recommended to protect these positive outcomes.

Parent and Provider Perspectives of a Hospital-Based Bereavement Support Program in Pediatric Palliative Care.

CONTEXT: Bereavement is an individuated, nuanced experience, and its expression is different for each parent who has cared for a dying child. Evidence highlights support is valuable to navigate this loss. OBJECTIVES: To evaluate a Bereavement Support Program from the perspectives of both families and service providers. METHODS: A cross-sectional study design explored the experiences and perspectives of the benefits of various program components. Respondents were asked about accessing program components, their expectations, and parents were asked to rate the impact of program components on their grief on a scale from one, (no impact) to 100 (positive impact). Space for free text was provided throughout for additional feedback. SETTING/ PARTICIPANTS: The survey was distributed through mailing lists of parents known to the service, referring service providers, and advertised in the program newsletter. RESULTS: One hundred two respondents completed the survey and provided detailed comments about their experiences. Most interactions and program components were reported helpful by both parents and service providers. Parents (N = 60) reported a positive impact on grief across all program components (median impact on grief range 81-98, Interquartile range 68.5-99). There were, however, a considerable number of respondents who were unaware of some components. CONCLUSION: Bereavement care to navigate the devastating loss of a child is of paramount importance and can offer significant and beneficial resources for families. Findings have supported service development in a major tertiary paediatric hospital facilitating improved access for families, particularly for those in regional and rural locations.

Characterisation of native and decellularised porcine tendon under tension and compression: A closer look at glycosaminoglycan contribution to tendon mechanics.

Decellularised porcine superflexor tendon (pSFT) has been characterised as a suitable scaffold for anterior cruciate ligament replacement, with dimensions similar to hamstring tendon autograft. However, decellularisation of tissues may reduce or damage extracellular matrix components, leading to undesirable biomechanical changes at a whole tissue scale. Although the role of collagen in tendons is well established, the mechanical contribution of glycosaminoglycans (GAGs) is less evident and could be altered by the decellularisation process. In this study, the contribution of GAGs to the tensile and compressive mechanical properties of pSFT was determined and whether decellularisation affected these properties by reducing GAG content or functionality. PSFTs were either enzymatically treated using chondroitinase ABC to remove GAGs or decellularised using previously established methods. Native, GAG-depleted and decellularised pSFT groups were then subjected to quantitative assays and biomechanical characterisation. In tension, specimens underwent stress relaxation and strength testing. In compression, specimens underwent confined compression testing. The GAG-depleted group was found to have circa 86% reduction of GAG content compared to native and decellularised groups. There was no significant difference in GAG content between native (3.75 ± 0.58 µg/mg) and decellularised (3.40 ± 0.37 µg/mg) groups. Stress relaxation testing discovered the time-independent and time-dependent relaxation moduli of the decellularised group were reduced ≥50% compared to native and GAG-depleted groups. However, viscoelastic behaviour of native and GAG-depleted groups resulted similar. Strength testing discovered no differences between native and GAG-depleted group's properties, albeit a reduction ∼20% for decellularised specimens' linear modulus and tensile strength compared to native tissue. In compression testing, the aggregate modulus was found to be circa 74% lower in the GAG-depleted group than the native and decellularised groups, while the zero-strain permeability was significantly higher in the GAG-depleted group (0.86 ± 0.65 mm4/N) than the decellularised group (0.03 ± 0.04 mm4/N). The results indicate that GAGs may significantly contribute to the mechanical properties of pSFT in compression, but not in tension. Furthermore, the content and function of GAGs in pSFTs are unaffected by decellularisation and the mechanical properties of the tissue remain comparable to native tissue.

Care at Your Fingertips: Codesign, Development, and Evaluation of the Oncology Hub App for Remote Symptom Management in Pediatric Oncology.

PURPOSE: To codesign, develop, and evaluate a smartphone app that includes patient-reported measures of symptoms and real-time advice in children's cancer. METHODS: The Oncology Hub is a comprehensive approach to symptom management that includes a suite of codesigned tools and resources including clinical algorithms to determine the level of concern, symptom management advice, and resources for families of children with cancer. The evaluation involved Think Aloud interviews with parent and adolescent patients to complete tasks in the app as well as a User Experience questionnaire (score range, 0-120) and qualitative feedback. The accuracy of algorithms was determined by repeated testing of inputs and outputs over 4 weeks. RESULTS: Design and wireframes were iteratively refined through consultation with parents and adolescents confirming the final design. Beta testing evaluation was then completed by 25 participants including two adolescents. Across all participants, 84% of tasks were easy to navigate, and the Oncology Hub demonstrated high usability, usefulness, and acceptability with participants' scores ranging between 90 and 120 (mean = 112.2, standard deviation = 9.43). Qualitative feedback was positive. Testing of algorithms identified inconsistencies in understanding between clinical research and coding teams; refinements were made until the expected response notifications were returned with 100% accuracy. CONCLUSION: Technology offers new ways to think about how clinicians and families communicate and share information to harness the best of community and hospital services. Understanding how information is exchanged using health apps, and how this affects clinical workflow is critical to successful implementation, and optimizing symptom assessment and management in children with cancer.

Building capability in paediatric palliative care and enhancing education through the voice of parents: the Quality of Care Collaborative Australia.

Background: The greater proportion of children with a life-limiting condition (LLC) and their families want to remain at home as much as possible. Building capability in paediatric palliative care (PPC) for generalist health and social care professionals in nonmetropolitan regions through the Quality of Care Collaborative Australia (QuoCCA) has improved access to palliative care for families, regardless of where they live. Aim: To understand the experience of families whose child has received specialist PPC, to ensure future service capability development is informed by lived experience. Design: A retrospective, descriptive study in which parents participated in a semi-structured telephone interview guided by Discovery Interview methodology. Inductive thematic analysis identified the major learnings from participants. Participants: Parents caring for a child referred to the specialist PPC service, who received a pop-up visit and whose child is stable or who are more than 6 months bereaved. Results: Eleven parents (n = 9 mothers; n = 2 fathers) of children with an LLC (n = 5) or whose child had died (n = 6) participated in an interview. The overarching themes and subthemes were as follows: (1) burden of suffering, in which parents described grieving for the life once anticipated, confronting many life transitions and seeking quality of life for their child and (2) umbrella of support, in which parents built partnerships with professional support, activated a network of care around their family and sought responses to their whole family's needs. Conclusion: Parents caring for a child with an LLC described significant personal, familial, social and existential adjustments. This study integrates a relational learning approach with QuoCCA education grounded in the relationships between children, families and professionals. Learning from lived experience in PPC education enhances the preparedness of generalist health and social care professionals to join a child and their family throughout their various life transitions and facilitates the goal to remain at home within their community for as long as possible. Education in PPC is an imperative component of service models, enabling regional services to gain confidence and capability in the context of a dying child and their family, empowered and informed through the voice of the family. Plain Language Summary: Enhancing palliative care for children through education informed by the experience of families It is often the wish of many children/young people with a life-limiting condition to stay at home with their families as much as possible. It is important that specialist palliative care services provide training and mentoring to the family's local care professionals to support the delivery of good care, particularly those in rural and remote areas.This article aims to integrate the lived experience of families with palliative care education, so that the education reflects and addresses the needs that they express.Parents were interviewed by telephone using a method called Discovery Interviews. This is an open interview process, guided by a spine that describes the main points of palliative care. Parents can openly talk about their experience, focusing on the areas that are important to them. Interviews were studied by four researchers, and emerging themes were discussed and summarised.The study included parents whose child/young person was receiving support from specialist palliative care and bereaved parents whose child had died more than 6 months ago. In total, eleven parents (nine mothers and two fathers) were interviewed, five participants had children currently receiving palliative care and six were bereaved.The overarching themes were as follows:Burden of suffering, in which parents described grieving for the life they had expected, confronting transitions and seeking good quality of life for their child.Umbrella of support, in which parents built partnerships with care teams and activated a network of care to address the needs of their whole family.This study allowed the families' perspectives to be integrated into the palliative care education of care professionals in the family's local area. The lived experience of families prepared care professionals to support families with the care of their child/young person, allowing them to remain at home as long as possible.

Interventions for interpersonal communication about end of life care between health practitioners and affected people.

BACKGROUND: Communication about end of life (EoL) and EoL care is critically important for providing quality care as people approach death. Such communication is often complex and involves many people (patients, family members, carers, health professionals). How best to communicate with people in the period approaching death is not known, but is an important question for quality of care at EoL worldwide. This review fills a gap in the evidence on interpersonal communication (between people and health professionals) in the last year of life, focusing on interventions to improve interpersonal communication and patient, family member and carer outcomes. OBJECTIVES: To assess the effects of interventions designed to improve verbal interpersonal communication about EoL care between health practitioners and people affected by EoL. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, PsycINFO, and CINAHL from inception to July 2018, without language or date restrictions. We contacted authors of included studies and experts and searched reference lists to identify relevant papers. We searched grey literature sources, conference proceedings, and clinical trials registries in September 2019. Database searches were re-run in June 2021 and potentially relevant studies listed as awaiting classification or ongoing. SELECTION CRITERIA: This review assessed the effects of interventions, evaluated in randomised and quasi-randomised trials, intended to enhance interpersonal communication about EoL care between patients expected to die within 12 months, their family members and carers, and health practitioners involved in their care. Patients of any age from birth, in any setting or care context (e.g. acute catastrophic injury, chronic illness), and all health professionals involved in their care were eligible. All communication interventions were eligible, as long as they included interpersonal interaction(s) between patients and family members or carers and health professionals. Interventions could be simple or complex, with one or more communication aims (e.g. to inform, skill, engage, support). Effects were sought on outcomes for patients, family and carers, health professionals and health systems, including adverse (unintended) effects. To ensure this review's focus was maintained on interpersonal communication in the last 12 months of life,  we excluded studies that addressed specific decisions, shared or otherwise, and the tools involved in such decision-making. We also excluded studies focused on advance care planning (ACP) reporting ACP uptake or completion as the primary outcome. Finally, we excluded studies of communication skills training for health professionals unless patient outcomes were reported as primary outcomes. DATA COLLECTION AND ANALYSIS: Standard Cochrane methods were used, including dual review author study selection, data extraction and quality assessment of the included studies. MAIN RESULTS: Eight trials were included. All assessed intervention effects compared with usual care. Certainty of the evidence was low or very low. All outcomes were downgraded for indirectness based on the review's purpose, and many were downgraded for imprecision and/or inconsistency. Certainty was not commonly downgraded for methodological limitations. A summary of the review's findings is as follows. Knowledge and understanding (four studies, low-certainty evidence; one study without usable data): interventions to improve communication (e.g. question prompt list, with or without patient and physician training) may have little or no effect on knowledge of illness and prognosis, or information needs and preferences, although studies were small and measures used varied across trials.  Evaluation of the communication (six studies measuring several constructs (communication quality, patient-centredness, involvement preferences, doctor-patient relationship, satisfaction with consultation), most low-certainty evidence): across constructs there may be minimal or no effects of interventions to improve EoL communication, and there is uncertainty about effects of interventions such as a patient-specific feedback sheet on quality of communication.  Discussions of EoL or EoL care (six studies measuring selected outcomes, low- or very low-certainty evidence): a family conference intervention may increase duration of EoL discussions in an intensive care unit (ICU) setting, while use of a structured serious illness conversation guide may lead to earlier discussions of EoL and EoL care (each assessed by one study). We are uncertain about effects on occurrence of discussions and question asking in consultations, and there may be little or no effect on content of communication in consultations.  Adverse outcomes or unintended effects (limited evidence): there is insufficient evidence to determine whether there are adverse outcomes associated with communication interventions  (e.g. question prompt list, family conference, structured discussions) for EoL and EoL care. Patient and/or carer anxiety was reported by three studies, but judged as confounded. No other unintended consequences, or worsening of desired outcomes, were reported. Patient/carer quality of life (four studies, low-certainty evidence; two without useable data): interventions to improve communication may have little or no effect on quality of life.  Health practitioner outcomes (three studies, low-certainty evidence; two without usable data): interventions to improve communication may have little or no effect on health practitioner outcomes (satisfaction with communication during consultation; one study); effects on other outcomes (knowledge, preparedness to communicate) are unknown. Health systems impacts: communication interventions (e.g. structured EoL conversations) may have little or no effect on carer or clinician ratings of quality of EoL care (satisfaction with care, symptom management, comfort assessment, quality of care) (three studies, low-certainty evidence), or on patients' self-rated care and illness, or numbers of care goals met (one study, low-certainty evidence). Communication interventions (e.g. question prompt list alone or with nurse-led communication skills training) may slightly increase mean consultation length (two studies), but other health service impacts (e.g. hospital admissions) are unclear. AUTHORS' CONCLUSIONS: Findings of this review are inconclusive for practice. Future research might contribute meaningfully by seeking to fill gaps for populations not yet studied in trials; and to develop responsive outcome measures with which to better assess the effects of communication on the range of people involved in EoL communication episodes. Mixed methods and/or qualitative research may contribute usefully to better understand the complex interplay between different parties involved in communication, and to inform development of more effective interventions and appropriate outcome measures. Co-design of such interventions and outcomes, involving the full range of people affected by EoL communication and care, should be a key underpinning principle for future research in this area.

Thinking globally to improve care locally: A Delphi study protocol to achieve international clinical consensus on best-practice end-of-life communication with adolescents and young adults with cancer.

For the sizeable subset of adolescents and young adults whose cancer is incurable, developmentally appropriate end-of-life discussions are critical. Standards of care for adolescent and young adult end-of-life communication have been established, however, many health-professionals do not feel confident leading these conversations, leaving gaps in the implementation of best-practice end-of-life communication. We present a protocol for a Delphi study informing the development and implementation of clinician training to strengthen health-professionals' capacity in end-of-life conversations. Our approach will inform training to address barriers to end-of-life communication with adolescents and young adults across Westernized Adolescent and Young Adult Cancer Global Accord countries. The Adolescent and Young Adult Cancer Global Accord team involves 26 investigators from Australia, New Zealand, the United States, Canada and the United Kingdom. Twenty-four consumers, including adolescents and young adults with cancer history and carers, informed study design. We describe methodology for a modified Delphi questionnaire. The questionnaire aims to determine optimal timing for end-of-life communication with adolescents and young adults, practice-related content needed in clinician training for end-of-life communication with adolescents and young adults, and desireability of evidence-based training models. Round 1 involves an expert panel of investigators identifying appropriate questionnaire items. Rounds 2 and 3 involve questionnaires of international multidisciplinary health-professionals, followed by further input by adolescents and young adults. A second stage of research will design health-professional training to support best-practice end-of-life communication. The outcomes of this iterative and participatory research will directly inform the implementation of best-practice end-of-life communication across Adolescent and Young Adult Cancer Global Accord countries. Barriers and training preferences identified will directly contribute to developing clinician-training resources. Our results will provide a framework to support further investigating end-of-life communication with adolescents and young adults across diverse countries. Our experiences also highlight effective methodology in undertaking highly collaborative global research.

How can advance care planning tools help young people's voices be heard?

The integration of the child or young person (CYP) in conversations around advance care planning (ACP) is an important area of paediatric practice. These discussions provide CYP with the opportunity to voice their values, goals and preferences, enabling health-care professionals to ensure they are aligned with their planned course of treatment. This process, often undertaken within the context of the child's family, empowers children to participate in decisions and experience the dignity of self-determination. It also facilitates an increased understanding between the CYP and those involved in their care. The objectives of this paper are to highlight the importance of these conversations for paediatricians and identify barriers, both real and perceived, that may prevent them from engaging with a CYP about their preferences for future care including focusing more on discussion with the parents, and concern about or not having the skills to engage the child in such sensitive conversations. Triggers that can prompt clinicians to undertake ACP are also discussed. A further complexity is that after seeking their perspective, it may become apparent that the CYP may hold different views and perspectives to their parents and/or clinician. This review article will especially examine elements of end-of-life conversations that are critical to support the important goal of listening to the voice of the CYP. This includes considerations around timing, legal aspects, ethical tensions that arise when amplifying a child's voice, clinician/team-member roles, clinical process considerations, and the use of specific interventions and ACP tools to facilitate these conversations with CYP.

Location of end-of-life care of children with cancer: A systematic review of parent experiences.

OBJECTIVE: To synthesize existing qualitative research exploring the experiences of parents caring for children with cancer during the end-of-life phase, and the factors that influence parental decision-making when choosing the location of end-of-life care and death for their child. RESULTS: This review included 15 studies of 460 parents of 333 children and adolescents who died from progressive cancer. Where reported, the majority (58%) of children died at home or in a hospital (39%), with only a small fraction dying in a hospice. Factors impacting decision-making for the location of care included the quality of communication and the quality of care available. Themes related to choosing home for end-of-life care and death included honoring the child's wishes, the familiarity of home, and parents' desire to be their child's primary carer. Preference for the location of death in the hospital included trust in hospital staff, practical logistics, and the safety of the hospital environment.

Attending to child agency in paediatric palliative care consultations: Adults' use of tag questions directed to the child.

Children's agency in their own lives is increasingly recognised as important, including within paediatric health care. The issue of acknowledging child agency is complex in the context of paediatric palliative care, where children have serious and complex conditions that often impact their ability to verbally communicate with others. This study explores how clinicians and parents/guardians direct talk towards a child patient when they are present in a consultation. Conversation analysis methods were used to examine 74 video-recorded paediatric palliative care consultations. Detailed turn-by-turn examination of the recorded consultations identified the recurrent use of a practice described by linguists as a 'tag question', which follows some statement (e.g. 'he loves that, don't ya'). Both clinicians and parents/guardians often directed these tag questions towards the child patient. Analysis demonstrated how these tag questions: (1) validated the child's epistemic authority over what was being said and (2) made a child's response a possible, but not necessary, next action. The findings are discussed in relation to the sociology of child agency and how this agency is acknowledged and displayed within and through social interaction. This research provides direct evidence of children's competence as informants about their own symptoms.

Decellularised human bone allograft from different anatomical sites as a basis for functionally stratified repair material for bone defects.

Tissue engineered bone solutions aim to overcome the limitations of autologous and allogeneic grafts. Decellularised tissues are produced by washing cellular components from human or animal tissue to produce an immunologically safe and biocompatible scaffold, capable of integration following implantation. A decellularisation procedure utilising low concentration sodium dodecyl sulphate (0.1% w/v) was applied to trabecular bone from human femoral heads (FH) and tibial plateaus (TP). Biological (histology, DNA quantification), biomechanical (compression testing) and structural (µCT) comparisons were made between decellularised and unprocessed cellular tissue. Total DNA levels of decellularised FH and TP bone were below 50 ng mg-1 dry tissue weight and nuclear material was removed. No differences were found between cellular and decellularised bone, from each anatomical region, for all the biomechanical and structural parameters investigated. Differences were found between cellular FH and TP and between decellularised FH and TP. Decellularised FH had a higher ultimate compressive stress, Young's modulus and 0.2% proof stress than decellularised TP (p = 0.001, 0.002, 0.001, Mann Whitney U test, MWU). The mineral density of cellular and decellularised TP bone was significantly greater than cellular and decellularised FH bone respectively (cellular: p = 0.001, decellularised: p < 0.001, MWU). The bone volume fraction and trabecular thickness of cellular and decellularised FH bone were significantly greater than cellular and decellularised TP bone respectively (cellular: p = 0.001, 0.005; decellularised: p < 0.001, <0.001, MWU). Characterisation of decellularised trabecular bone from different anatomical regions offers the possibility of product stratification, allowing selection of biomechanical properties to match particular anatomical regions undergoing bone graft procedures.

Analysis of health administration data to inform health service planning for paediatric palliative care.

BACKGROUND: Health service planning in paediatric palliative care is complex, with the diverse geographical and demographic characteristics adding to the challenge of developing services across different nations. Accurate and reliable data are essential to inform effective, efficient and equitable health services. AIM: To quantify health service usage by children and young people aged 0-21 years with a life-limiting condition admitted to hospital and health service facilities in Queensland, Australia during the 2011 and 2016 calendar years, and describe the clinical and demographic characteristics associated with health services usage. DESIGN: Retrospective health administrative data linkage of clinical and demographic information with hospital admissions was extracted using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision Australian Modification (ICD-10-AM) diagnostic codes. Data were analysed using descriptive statistics. SETTING/PARTICIPANTS: Individuals aged 0-21 years with a life-limiting condition admitted to a Queensland Public Hospital and Health Service or private hospital. RESULTS: Hospital admissions increased from 17 955 in 2011 to 23 273 in 2016, an increase of 5318 (29.6%). The greatest percentage increase in admissions were for those aged 16-18 years (58.1%, n=1050), and those with non-oncological conditions (36.2%, n=4256). The greatest number of admissions by ICD-10-AM chapter for 2011 and 2016 were by individuals with neoplasms (6174, 34.4% and 7206, 31.0% respectively). Overall, the number of admissions by Indigenous children and young people increased by 70.2% (n=838). CONCLUSIONS: Administrative data are useful to describe clinical and demographic characteristics and quantify health service usage. Available data suggest a growing demand for health services by children eligible for palliative care that will require an appropriate response from health service planners.

Integration and functional performance of a decellularised porcine superflexor tendon graft in an ovine model of anterior cruciate ligament reconstruction.

The objective was to evaluate the performance of decellularised porcine superflexor tendon (pSFT) as an anterior cruciate ligament (ACL) reconstruction device. The ACL of adult sheep was reconstructed with decellularised pSFT or ovine allograft SFT and animals sacrificed at 4, 12 and 26 weeks (n = 4 per group) for biological evaluation and 26 weeks (n = 6) for biomechanical evaluation of the grafts. Both grafts showed good in vivo performance with no major differences at macroscopic evaluation post euthanasia. Histopathology revealed an inflammatory reaction to both grafts at 4 weeks, which reduced by 26 weeks. There was advanced cellular ingrowth from 12 weeks, ligamentisation of intra-articular grafts, ossification and formation of Sharpey's fibers at the graft/bone junctions. Immunohistochemistry showed that at 4 and 12 weeks, the host response was dominated by CD163+ M2 macrophages and a cell infiltrate comprising α-SMA + myofibroblasts, CD34+ and CD271+ progenitor cells. At 26 weeks the biomechanical properties of decellularised pSFT and oSFT grafts were comparable, with all grafts failing in the intra-articular region. This study provides new insight into constructive remodelling of tendons used for ACL replacement and evidence of integration and functional performance of a decellularised xenogeneic tendon with potential as an alternative for ACL reconstruction.

Ongoing Value and Practice Improvement Outcomes from Pediatric Palliative Care Education: The Quality of Care Collaborative Australia.

PURPOSE: Novice and experienced professionals who care for children with life limiting conditions throughout Australia were provided with pediatric palliative care (PPC) education through the Quality of Care Collaborative Australia (QuoCCA). Impact evaluation has shown this education to be beneficial. This study examines the longer term outcomes reported by the participants more than 4 months following education. METHODS: An online survey measuring quantitative and qualitative education outcomes was sent to all participants of QuoCCA 2 education throughout Australia, at least 4 months following their education. There were 152 respondents between February 2018 and June 2020. RESULTS: More than 4 months after the QuoCCA education, 98% of respondents rated it as extremely valuable or valuable and 78% of respondents rated it extremely or very helpful in improving clinical practice. Improvements in knowledge, skills or confidence were reported by 90% or more respondents in the areas of PPC referral, responding to psychosocial needs, the benefits of the PPC approach, PPC resources and communication skills. Between 84% and 89% of respondents reported improvements in advance care planning, assessment and intervention, responding to physical needs, supporting spiritual needs and supporting health professionals and self care. Providing bereavement care improved in 85% of responses. The most valuable aspects of the education, changes in practice and barriers to the implementation of learning were discussed. CONCLUSION: The interprofessional QuoCCA education in PPC continued to provide value and clinical practice improvements for the majority of respondents more than four months after the session. Respondents particularly mentioned improvements in awareness of the network of care, the practical management of patients and communication skills. Reflection on clinical practice, in a proactive clinical learning environment, enabled the translation of education into improvements to the quality of PPC.
