The Use of Person-Centered Outcome Measures to Support Integrated Palliative Care for Older People: A Systematic Review.

OBJECTIVES: The aim was to synthesize evidence on the use of person-centered outcome measures to facilitate integrated palliative care for older people and build a logic model depicting the mechanisms through which person-centered outcome measures support integrated care. DESIGN: Mixed methods systematic review using a data-based convergent synthesis design. SETTING AND PARTICIPANTS: Older people aged ≥60 years who are approaching the end of their lives in multiple settings. METHODS: The study was underpinned by a conceptual framework of integrated palliative care, which informed the search strategy, data extraction, analysis, and synthesis. A hybrid search strategy was implemented, with database searches (PsycINFO, MEDLINE, CINAHL, and ASSIA) complemented by snowball searches. Qualitative and quantitative data were analyzed by narrative synthesis to summarize and explain the findings. The findings informed a logic model depicting the mechanisms of using person-centered outcome measures to support integrated palliative care. RESULTS: Twenty-six studies were included. Three mixed methods studies, 2 qualitative studies, and 21 quantitative studies were included. There was evidence that person-centered outcome measures could support integrated palliative care through informing palliative care policy development (n = 4), facilitating joint working across settings (n = 5), enabling close collaboration of multidisciplinary teams (n = 14), promoting joint education (n = 1), facilitating timing and specialist referral (n = 6), and enhancing patient-centered care (n = 3). CONCLUSIONS AND IMPLICATIONS: This review makes an important, novel, and theoretically informed contribution to the delivery of scalable and sustainable integrated palliative care into the care of older people using person-centered outcome measures. The constructed logic model provides a conceptual framework and practical approach to how person-centered outcome measures support multilevel integration. A future area of research is the development of person-centered outcome measure interventions informed by the logic model to meet clinical needs.

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.

The Updated Mouse Universal Genotyping Array Bioinformatic Pipeline Improves Genetic QC in Laboratory Mice.

The MiniMUGA genotyping array is a popular tool for genetic QC of laboratory mice and genotyping of samples from most types of experimental crosses involving laboratory strains, particularly for reduced complexity crosses. The content of the production version of the MiniMUGA array is fixed; however, there is the opportunity to improve array's performance and the associated report's usefulness by leveraging thousands of samples genotyped since the initial description of MiniMUGA in 2020. Here we report our efforts to update and improve marker annotation, increase the number and the reliability of the consensus genotypes for inbred strains and increase the number of constructs that can reliably be detected with MiniMUGA. In addition, we have implemented key changes in the informatics pipeline to identify and quantify the contribution of specific genetic backgrounds to the makeup of a given sample, remove arbitrary thresholds, include the Y Chromosome and mitochondrial genome in the ideogram, and improve robust detection of the presence of commercially available substrains based on diagnostic alleles. Finally, we have made changes to the layout of the report, to simplify the interpretation and completeness of the analysis and added a table summarizing the ideogram. We believe that these changes will be of general interest to the mouse research community and will be instrumental in our goal of improving the rigor and reproducibility of mouse-based biomedical research.

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.

Co-design of the EMBED-Care Framework as an intervention to enhance shared decision-making for people affected by dementia and practitioners, comprising holistic assessment, linked with clinical decision support tools: A qualitative study.

INTRODUCTION: Shared decision-making intends to align care provision with individuals' preferences. However, the involvement of people living with dementia in decision-making about their care varies. We aimed to co-design the EMBED-Care Framework, to enhance shared decision-making between people affected by dementia and practitioners. METHODS: A theory and evidence driven co-design study was conducted, using iterative workshops, informed by a theoretical model of shared decision-making and the EMBED-Care Framework (the intervention) for person-centred holistic palliative dementia care. The intervention incorporates a holistic outcome measure for assessment and review, linked with clinical decision-support tools to support shared decision-making. We drew on the Medical Research Council (MRC) guidance for developing and evaluating complex interventions. Participants included people with dementia of any type, current or bereaved family carers and practitioners. We recruited via established dementia groups and research and clinical networks. Data were analysed using reflexive thematic analysis to explore how and when the intervention could enhance communication and shared decision-making, and the requirements for use, presented as a logic model. RESULTS: Five co-design workshops were undertaken with participants comprising people affected by dementia (n = 18) and practitioners (n = 36). Three themes were generated, comprising: (1) 'knowing the person and personalisation of care', involving the person with dementia and/or family carer identifying the needs of the person using a holistic assessment. (2) 'engaging and considering the perspectives of all involved in decision-making' required listening to the person and the family to understand their priorities, and to manage multiple preferences. (3) 'Training and support activities' to use the Framework through use of animated videos to convey information, such as to understand the outcome measure used to assess symptoms. CONCLUSIONS: The intervention developed sought to enhance shared decision-making with individuals affected by dementia and practitioners, through increased shared knowledge of individual priorities and choices for care and treatment. The workshops generated understanding to manage disagreements in determining priorities. Practitioners require face-to-face training on the intervention, and on communication to manage sensitive conversations about symptoms, care and treatment with individuals and their family. The findings informed the construction of a logic model to illustrate how the intervention is intended to work.

What are the barriers and facilitators to advance care planning with older people in long-term care facilities? A qualitative study.

AIM: To explore the views and preferences for advance care planning from the perspectives of residents, family members and healthcare professionals in long-term care facilities. DESIGN: A qualitative descriptive design. METHODS: We conducted semi-structured interviews with 12 residents of long-term care facilities, 10 family members and 14 healthcare professionals. Data were analysed using reflexive thematic analysis. The social ecological model was used to develop implementation recommendations. RESULTS: We constructed a conceptual model of barriers and facilitators to advance care planning in long-term care facilities, drawing upon four dominant themes from the qualitative analysis: (1) The absence of discourse on end-of-life care: a lack of cultural climate to talk about death, the unspoken agreement to avoid conversations about death, and poor awareness of palliative care may hinder advance care planning initiation; (2) Relational decision-making process is a dual factor affecting advance care planning engagement; (3) Low trust and 'unsafe' cultures: a lack of honest information sharing, risks of violating social expectations and damaging social relationships, and risks of legal consequences may hinder willingness to engage in advance care planning; (4) Meeting and respecting residents' psychosocial needs: these can be addressed by readiness assessment, initiating advance care planning in an informal and equal manner and involving social workers. CONCLUSION: Our findings show that residents' voices were not being heard. It is necessary to identify residents' spontaneous conversation triggers, articulate the value of advance care planning in light of the family's values and preferences, and respect residents' psychosocial needs to promote advance care planning in long-term care facilities. Advance care planning may alleviate the decision-making burden of offspring in nuclear families. IMPLICATIONS FOR CLINICAL PRACTICE: The evidence-based recommendations in this study will inform the implementation of context-specific advance care planning in Asia-Pacific regions. PATIENT AND PUBLIC CONTRIBUTION: Patients and caregivers contributed to the interview pilot and data collection.

A randomised controlled trial of the effectiveness of parent-based models of language intervention for 2- to 3-year-old children with speech, language and communication needs (SLCN) in areas of social disadvantage.

BACKGROUND: Early language delay is exacerbated by social disadvantage. Factors such as parents' low levels of literacy, confidence and self-perception can affect the capacity to act on advice received, critical to empowerment. Methods used to achieve successful health outcomes in socially disadvantaged clinical populations may need enhancing. AIMS: To compare the impact of standard parent-based intervention (PBI) to enhanced PBI for young children with speech, language and communication needs (SCLN) and their families living in more socially disadvantaged populations. METHODS AND PROCEDURES: A multicentre clustered blind randomised controlled trial was used to compare the effect of parent-based group interventions to improve early language development with children (mean age 27.5 months) from more socially disadvantaged populations with an expressive vocabulary of 40 or less single words. Intervention sessions were delivered by a speech and language therapist, over a 20-week period. Participants received one of two interventions: (1) Standard Care - indirect group PBI - (PBI) (2) Enhanced Care: indirect group enhanced PBI - (EPBI). Both standardised and non-standardised measures were used as outcomes. Parent engagement in the intervention was captured through analysis of attendance and the Parent Activation Measure - Speech & Language Therapy (PAM-SLT) (Insignia Health, 2014). The PAM measures a person's knowledge, skills and confidence to manage their own health and well-being (NHS England, 2018). In this study, activation referred to parents' knowledge, skills and confidence to manage their child's language development. OUTCOMES AND RESULTS: One hundred fifty-five participants were randomised at baseline. Children in both groups made significant improvements in the outcome on MacArthur-Bates Communicative Development Inventories Sentence Length, from pre-intervention to post-intervention and 6 months post-intervention (p < 0.05). Changes in vocabulary and expressive language skills were more equivocal, showing wide variation in confidence intervals for both groups. Where parents attended at least one intervention session almost all effect sizes were in favour of the EPBI intervention. Parents' activation levels significantly increased for both groups (EPBI p < 0.001, PBI p = 0.003), with a moderate effect size in favour of EPBI (Hedges' G 0.37, confidence interval -0.02 to 0.76), although wide variation was found. CONCLUSIONS AND IMPLICATIONS: This trial provides some evidence of facilitating the language development of children with SLCN from more socially disadvantaged areas through supporting caregivers. However, we found variation in outcomes; some children made excellent progress, whilst others did not. Further exploration of parent engagement and its relationship to child language outcomes will be valuable to understanding more about mechanisms of change in interventions that involve parents. WHAT THIS PAPER ADDS: What is already known on the subject Speech, language and communication needs (SLCN) have a knock-on effect on emotional well-being, school readiness, literacy and school attainment, putting children at increased risk of long-term consequences such as poor literacy, mental health problems and unemployment. In disadvantaged areas, the prevalence of language difficulties is higher than elsewhere. Factors such as parents' low levels of literacy, confidence and self-perception can affect the capacity to act on advice received, critical to empowerment. What this paper adds to existing knowledge Children with SLCN from more socially disadvantaged areas can make improvements in their language development through parent intervention, although wide individual variation was found. There was some evidence that children achieve better outcomes with EPBI, which employed an interagency collaborative approach. Parent's engagement (activation levels) increased significantly over time with intervention, with the increase twice as big for EPBI. What are the potential or actual clinical implications of this work? This trial provides some evidence that it is possible to facilitate the language development of children from more socially disadvantaged areas through supporting their caregivers. Further research would be useful to determine whether increases in parent engagement are related to adherence to intervention and change in child outcomes.

Elexacaftor-Tezacaftor-Ivacaftor in 2 cystic fibrosis adults homozygous for M1101K with end-stage lung disease.

Elexacaftor-tezacaftor-ivacaftor (ETI) therapy is shown to improve the health of individuals with cystic fibrosis (CF) who have the F508del variant. There are in vitro studies showing benefit with ETI for select rare CF variants. Limited data exists on the use of ETI in individuals with rare CF variants, particularly in those with advanced lung disease. We present 2 cases of CF individuals homozygous for the rare M1101K variant with end-stage lung disease who demonstrated sustained improvements in lung function, pulmonary exacerbation frequency, respiratory symptoms, and body mass index after 6 months of ETI treatment - similar to that expected with F508del.

Co-design of a theory-based implementation plan for a holistic eHealth assessment and decision support framework for people with dementia in care homes.

Background: Despite positive findings around the use of eHealth in dementia care, it is rarely translated into routine practice. This can be facilitated by early involvement of end-users in the development of an implementation plan. This study aimed to co-design strategies to implement an eHealth intervention, the EMBED-Care Framework, to support assessment and decision-making for people with dementia in care homes. Methods: A qualitative co-design method was applied through a series of workshops. Participants included family carers and health and social care practitioners. People with dementia were included through a series of stakeholder engagement meetings. The workshops focused on co-developing strategies in response to identified determinants of implementation. A codebook thematic analytic approach was taken, guided by the Normalisation Process Theory (NPT). Results: Three workshops were conducted from July 2021 to November 2021, attended by 39 participants. Three overarching phases of implementation were identified which aligned with the constructs of the NPT: (a) incentivising adoption of the Framework, which requires promotion of its benefits and alignment with recommendations for good quality dementia care to engage stakeholders, relating to 'coherence' and 'cognitive participation' constructs; (b) enabling its operation, which requires ensuring compatibility with care home processes, provision of training and support from 'champions', relating to 'collective action'; (c) sustaining use of the Framework, which requires monitoring of implementation and appraisal of its effects, relating to 'reflexive monitoring'. Conclusions: We have developed a multi-strategy, theoretically driven plan to implement eHealth to support assessment and decision-making for people with dementia in care homes. Successful implementation requires incentivisation to adopt, ability to operate and motivation to sustain use of eHealth. The plan is strengthened through collaborating with end-users to increase its value, credibility and real-world relevance. The theoretically informed strategies target mechanisms of the NPT, demonstrated to shape the implementation process and outcomes, ready for testing.

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.

Complexity and function of family involvement in advance care planning: A qualitative study of perspectives from people living with advanced cancer, family members and healthcare professionals.

BACKGROUND: Family members can support advance care planning conversations. However, how family involvement in advance care planning operates to achieve goal-concordant care remains unclear. AIM: To explore how family involvement impacts the process of advance care planning for advanced cancer patients and their family members to achieve goal-concordant care in Japan. DESIGN: Qualitative study incorporating semi-structured in-depth interviews with thematic analysis informed by Family Systems Theory. SETTING/PARTICIPANTS: Medical oncology departments at two tertiary hospitals in Japan. A purposive sample of 13 advanced cancer patients, 10 family members and 9 healthcare professionals who cared for them. RESULTS: Twenty-five interviews were conducted, comprising 7 dyads of patients and their family members and 18 individual interviews. Four themes were identified: characteristics of patients and family members and their views on illness and advance care planning; family context and communication; interactions with healthcare professionals and societal and cultural influences; and family members' acceptance, preparation and confidence. Family involvement was observed as being variable at an individual level and also across generations. Family members provided patients with the instrumental and emotional support that facilitated the advance care planning process. Family involvement enabled family members to better prepare for realising patients' wishes. It increased family members' confidence in surrogate decision-making. CONCLUSIONS: Two mechanisms of how family involvement may enable goal-concordant care were identified: family members' support provision and their preparation for realising patients' wishes. Healthcare professionals should assess family's readiness to engage in advance care planning, and the time required to prepare them for the process.

Glycerol contributes to tuberculosis susceptibility in male mice with type 2 diabetes.

Diabetes mellitus increases risk for tuberculosis disease and adverse outcomes. Most people with both conditions have type 2 diabetes, but it is unknown if type 1 and type 2 diabetes have identical effects on tuberculosis susceptibility. Here we show that male mice receiving a high-fat diet and streptozotocin to model type 2 diabetes, have higher mortality, more lung pathology, and higher bacterial burden following Mycobacterium tuberculosis infection compared to mice treated with streptozotocin or high-fat diet alone. Type 2 diabetes model mice have elevated plasma glycerol, which is a preferred carbon source for M. tuberculosis. Infection studies with glycerol kinase mutant M. tuberculosis reveal that glycerol utilization contributes to the susceptibility of the type 2 diabetes mice. Hyperglycemia impairs protective immunity against M. tuberculosis in both forms of diabetes, but our data show that elevated glycerol contributes to an additional adverse effect uniquely relevant to type 2 diabetes.

Genome-wide screen identifies host loci that modulate Mycobacterium tuberculosis fitness in immunodivergent mice.

Genetic differences among mammalian hosts and among strains of Mycobacterium tuberculosis (Mtb) are well-established determinants of tuberculosis (TB) patient outcomes. The advent of recombinant inbred mouse panels and next-generation transposon mutagenesis and sequencing approaches has enabled dissection of complex host-pathogen interactions. To identify host and pathogen genetic determinants of Mtb pathogenesis, we infected members of the highly diverse BXD family of strains with a comprehensive library of Mtb transposon mutants (TnSeq). Members of the BXD family segregate for Mtb-resistant C57BL/6J (B6 or B) and Mtb-susceptible DBA/2J (D2 or D) haplotypes. The survival of each bacterial mutant was quantified within each BXD host, and we identified those bacterial genes that were differentially required for Mtb fitness across BXD genotypes. Mutants that varied in survival among the host family of strains were leveraged as reporters of "endophenotypes," each bacterial fitness profile directly probing specific components of the infection microenvironment. We conducted quantitative trait loci (QTL) mapping of these bacterial fitness endophenotypes and identified 140 host-pathogen QTL (hpQTL). We located a QTL hotspot on chromosome 6 (75.97-88.58 Mb) associated with the genetic requirement of multiple Mtb genes: Rv0127 (mak), Rv0359 (rip2), Rv0955 (perM), and Rv3849 (espR). Together, this screen reinforces the utility of bacterial mutant libraries as precise reporters of the host immunological microenvironment during infection and highlights specific host-pathogen genetic interactions for further investigation. To enable downstream follow-up for both bacterial and mammalian genetic research communities, all bacterial fitness profiles have been deposited into GeneNetwork.org and added into the comprehensive collection of TnSeq libraries in MtbTnDB.

Implementation of child-centred outcome measures in routine paediatric healthcare practice: a systematic review.

BACKGROUND: Person-centred outcome measures (PCOMs) are commonly used in routine adult healthcare to measure and improve outcomes, but less attention has been paid to PCOMs in children's services. The aim of this systematic review is to identify and synthesise existing evidence of the determinants, strategies, and mechanisms that influence the implementation of PCOMs into paediatric healthcare practice. METHODS: The review was conducted and reported in accordance with PRISMA guidelines. Databased searched included CINAHL, Embase, Medline, and PsycInfo. Google scholar was also searched for grey literature on 25th March 2022. Studies were included if the setting was a children's healthcare service, investigating the implementation or use of an outcome measure or screening tool in healthcare practice, and reported outcomes relating to use of a measure. Data were tabulated and thematically analysed through deductive coding to the constructs of the adapted-Consolidated Framework for Implementation Research (CFIR). Results were presented as a narrative synthesis, and a logic model developed. RESULTS: We retained 69 studies, conducted across primary (n = 14), secondary (n = 13), tertiary (n = 37), and community (n = 8) healthcare settings, including both child self-report (n = 46) and parent-proxy (n = 47) measures. The most frequently reported barriers to measure implementation included staff lack of knowledge about how the measure may improve care and outcomes; the complexity of using and implementing the measure; and a lack of resources to support implementation and its continued use including funding and staff. The most frequently reported facilitators of implementation and continued use include educating and training staff and families on: how to implement and use the measure; the advantages of using PCOMs over current practice; and the benefit their use has on patient care and outcomes. The resulting logic model presents the mechanisms through which strategies can reduce the barriers to implementation and support the use of PCOMs in practice. CONCLUSIONS: These findings can be used to support the development of context-specific implementation plans through a combination of existing strategies. This will enable the implementation of PCOMs into routine paediatric healthcare practice to empower settings to better identify and improve child-centred outcomes.

Design and Administration of Patient-Centred Outcome Measures: The Perspectives of Children and Young People with Life-Limiting or Life-Threatening Conditions and Their Family Members.

BACKGROUND: Self-reported health data from children with life-limiting conditions is rarely collected. To improve acceptability and feasibility of child and family-centred outcome measures for children, they need to be designed in a way that reflects preferences, priorities and abilities. OBJECTIVES: The aim was to identify preferences for patient-reported outcome measure design (recall period, response format, length, administration mode) to improve the feasibility, acceptability, comprehensibility and relevance of a child and family-centred outcome measure, among children with life-limiting conditions and their family members. METHOD: A semi-structured qualitative interview study seeking the perspectives of children with life-limiting conditions, their siblings and parents on measure design was conducted. Participants were purposively sampled and recruited from nine UK sites. Verbatim transcripts were analysed using framework analysis. RESULTS: A total of 79 participants were recruited: 39 children aged 5-17 years (26 living with a life-limiting condition; 13 healthy siblings) and 40 parents (of children aged 0-17 years). Children found a short recall period and a visually appealing measure with ten questions or fewer most acceptable. Children with life-limiting conditions were more familiar with using rating scales such as numeric and Likert than their healthy siblings. Children emphasised the importance of completing the measure alongside interactions with a healthcare professional to enable them to talk about their responses. While parents assumed that electronic completion methods would be most feasible and acceptable, a small number of children preferred paper. CONCLUSIONS: This study demonstrates that children with life-limiting conditions can engage in communicating preferences regarding the design of a patient-centred outcome measure. Where possible, children should be given the opportunity to participate in the measure development process to enhance acceptability and uptake in clinical practice. Results of this study should be considered in future research on outcome measure development in children.

Mycobacterial Genetic Technologies for Probing the Host-Pathogen Microenvironment.

Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is one of the oldest and most successful pathogens in the world. Diverse selective pressures encountered within host cells have directed the evolution of unique phenotypic traits, resulting in the remarkable evolutionary success of this largely obligate pathogen. Despite centuries of study, the genetic repertoire utilized by Mtb to drive virulence and host immune evasion remains to be fully understood. Various genetic approaches have been and continue to be developed to tackle the challenges of functional gene annotation and validation in an intractable organism such as Mtb. In vitro and ex vivo systems remain the primary approaches to generate and confirm hypotheses that drive a general understanding of mycobacteria biology. However, it remains of great importance to characterize genetic requirements for successful infection within a host system as in vitro and ex vivo studies fail to fully replicate the complex microenvironment experienced by Mtb. In this review, we evaluate the employment of the mycobacterial genetic toolkit to probe the host-pathogen interface by surveying the current state of mycobacterial genetic studies within host systems, with a major focus on the murine model. Specifically, we discuss the different ways that these tools have been utilized to examine various aspects of infection, including bacterial survival/virulence, bacterial evasion of host immunity, and development of novel antibacterial/vaccine strategies.

Genome-wide screen identifies host loci that modulate M. tuberculosis fitness in immunodivergent mice.

Genetic differences among mammalian hosts and Mycobacterium tuberculosis ( Mtb ) strains determine diverse tuberculosis (TB) patient outcomes. The advent of recombinant inbred mouse panels and next-generation transposon mutagenesis and sequencing approaches has enabled dissection of complex host- pathogen interactions. To identify host and pathogen genetic determinants of Mtb pathogenesis, we infected members of the BXD family of mouse strains with a comprehensive library of Mtb transposon mutants (TnSeq). Members of the BXD family segregate for Mtb -resistant C57BL/6J (B6 or B ) and Mtb -susceptible DBA/2J (D2 or D ) haplotypes. The survival of each bacterial mutant was quantified within each BXD host, and we identified those bacterial genes that were differentially required for Mtb fitness across BXD genotypes. Mutants that varied in survival among the host family of strains were leveraged as reporters for "endophenotypes", each bacterial fitness profile directly probing specific components of the infection microenvironment. We conducted QTL mapping of these bacterial fitness endophenotypes and identified 140 h ost- p athogen quantitative trait loci ( hp QTL). We identified a QTL hotspot on chromosome 6 (75.97-88.58 Mb) associated with the genetic requirement of multiple Mtb genes; Rv0127 ( mak ), Rv0359 ( rip2 ), Rv0955 ( perM ), and Rv3849 ( espR ). Together, this screen reinforces the utility of bacterial mutant libraries as precise reporters of the host immunological microenvironment during infection and highlights specific host-pathogen genetic interactions for further investigation. To enable downstream follow-up for both bacterial and mammalian genetic research communities, all bacterial fitness profiles have been deposited into GeneNetwork.org and added into the comprehensive collection of TnSeq libraries in MtbTnDB.

Provision of palliative and end-of-life care in UK care homes during the COVID-19 pandemic: A mixed methods observational study with implications for policy.

Introduction: Little consideration has been given to how the provision of palliative and end-of-life care in care homes was affected by COVID-19. The aims of this study were to: (i) investigate the response of UK care homes in meeting the rapidly increasing need for palliative and end-of-life care during the COVID-19 pandemic and (ii) propose policy recommendations for strengthening the provision of palliative and end-of-life care within care homes. Materials and methods: A mixed methods observational study was conducted, which incorporated (i) an online cross-sectional survey of UK care homes and (ii) qualitative interviews with care home practitioners. Participants for the survey were recruited between April and September 2021. Survey participants indicating availability to participate in an interview were recruited using a purposive sampling approach between June and October 2021. Data were integrated through analytic triangulation in which we sought areas of convergence, divergence, and complementarity. Results: There were 107 responses to the survey and 27 interviews. We found that (i) relationship-centered care is crucial to high-quality palliative and end-of-life care within care homes, but this was disrupted during the pandemic. (ii) Care homes' ability to maintain high-quality relationship-centered care required key "pillars" being in place: integration with external healthcare systems, digital inclusion, and a supported workforce. Inequities within the care home sector meant that in some services these pillars were compromised, and relationship-centered care suffered. (iii) The provision of relationship-centered care was undermined by care home staff feeling that their efforts and expertise in delivering palliative and end-of-life care often went unrecognized/undervalued. Conclusion: Relationship-centered care is a key component of high-quality palliative and end-of-life care in care homes, but this was disrupted during the COVID-19 pandemic. We identify key policy priorities to equip care homes with the resources, capacity, and expertise needed to deliver palliative and end-of-life care: (i) integration within health and social care systems, (ii) digital inclusivity, (iii) workforce development, (iv) support for care home managers, and (v) addressing (dis)parities of esteem. These policy recommendations inform, extend, and align with policies and initiatives within the UK and internationally.

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.
