Understanding how shared decision-making approaches and patient aids influence patients with advanced cancer when deciding on palliative treatments and care: A realist review

BACKGROUND

Patients with advanced incurable cancer face difficult decisions about palliative treatment options towards their end of life. However, they are often not provided with the appropriate information and support that is needed to make informed decisions. This review aimed to identify contexts and mechanisms associated with communication tools, patient decision-aids and shared decision-making (SDM) approaches that influence patient outcomes.

METHODS

We used a realist review method to search for published studies of patients (adults > 18) with advanced cancer who were expected to make a decision about palliative treatment and/or supportive care in consultation with healthcare practitioners. We appraised and synthesised literature describing the contexts of (when and how) decision aids and SDM approaches are used, and how these contexts interact with mechanisms (resources and reasoning) which impact patient outcomes. Stakeholders including academics, palliative healthcare professionals (HCPs) and people with lived experience of supporting people with advanced incurable cancer contributed to identifying explanatory accounts. These accounts were documented, analysed and consolidated to contribute to the development of a programme theory.

RESULTS

From the 33 included papers, we consolidated findings into 20 explanatory accounts to develop a programme theory that explains key contexts and mechanisms that influence patient and SDM. Contexts include underlying patients' and HCPs' attitudes and approaches. These need to be understood in relation to key mechanisms, including presenting information in multiple formats and providing adequate time and opportunities to prepare for and revisit decisions. Contexts influenced mechanisms which then influence the levels of patient decisional satisfaction, conflict and regret.

CONCLUSIONS

Our programme theory highlights mechanisms that are important in supporting shared treatment decisions for advanced noncurative cancer. The findings are informative for developing and evaluating interventions to improve understanding and involvement in SDM for patients with advanced incurable cancer.

PATIENT AND PUBLIC CONTRIBUTION

We included patient and public involvement (PPI) representatives in four stakeholder meetings. PPI helped to define the scope of the review, identify their unique experiences and perspectives, synthesise their perspectives with our review findings, make decisions about which theories we included in our programme theory and develop recommendations for policy and practice and future research.

What matters to families about the healthcare of preterm or low birth weight infants: A qualitative evidence synthesis

OBJECTIVE

We examined what matters to families about the healthcare provided to preterm or LBW infants in hospital and the community, to ensure that care meets the needs of infants and parents.

METHODS

We searched databases to identify eligible studies examining the views and expectations of families. Study quality was assessed using the CASP checklist for qualitative studies. The GRADE-CERQual approach was used to assess confidence in review findings. Studies were sampled and data analysed using thematic synthesis.

RESULTS

222 studies (227 papers) were eligible for inclusion. 54 studies (57 papers) were sampled based on data richness, methodological quality, and representation across settings. Eight analytical themes were identified. Confidence in results was moderate to high. What mattered was a positive outcome for the child; active involvement in care; being supported to cope at home after discharge; emotional support; the healthcare environment; information needs met; logistical support available; and positive relationships with staff.

CONCLUSION

Although parents and family members reported a variety of experiences in the care of their infant, we found high consistency in what matters to families.

PRACTICE IMPLICATIONS

This review identifies approaches to improve experiences of parents which are consistent with the Family Centred Care model of healthcare.

Perceptions of friendship, peers and influence on adolescent smoking according to tobacco control context: a systematic review and meta-ethnography of qualitative research

BACKGROUND

A relationship between smoking and interpersonal influences has been well established within the literature. There have been cultural shifts in denormalisation and a reduction in tobacco smoking in many countries. Hence there is a need to understand social influences on adolescents' smoking across smoking normalisation contexts.

METHODS

The search was conducted in July 2019 and updated in March 2022 within 11 databases and secondary sources. Search terms included schools, adolescents, smoking, peers, social norms and qualitative research. Screening was conducted by two researchers independently and in duplicate. Study quality was assessed using the eight-item Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI-centre) tool for the appraisal of qualitative studies. Results were synthesised using a meta-narrative lens for meta-ethnography and compared across smoking normalisation contexts.

RESULTS

Forty one studies were included and five themes were developed, mapping onto the socio ecological model. The social processes by which adolescents take up smoking differed according to a mixture of school type, peer group structure and the smoking culture within the school, as well as the wider cultural context. Data available from smoking denormalised contexts, described changes in social interactions around smoking to cope with its stigmatisation. This was manifested through i) direct peer influence, whereby subtle techniques were employed, ii) group belonging whereby smoking was less likely to be seen as a key determinant of group membership and smoking was less commonly reported to be used as a social tool, and iii) popularity and identity construction, whereby smoking was perceived more negatively in a denormalised context, compared with a normalised context.

CONCLUSIONS

This meta-ethnography is the first study to demonstrate, drawing on international data, that peer processes in adolescent smoking may undergo changes as smoking norms within society change. Future research should focus on understanding differences across socioeconomic contexts, to inform the adaptation of interventions.

What matters to families about the healthcare of preterm or low birth weight infants

Introduction

Preterm and low birth weight (LBW) infants have complex long-term healthcare needs. The impact on families of caring for a sick infant is increasingly understood, with consequences for attachment and bonding and parental health and wellbeing immediately after birth and beyond. In this qualitative evidence synthesis, we aimed to understand what matters to families about the care provided to preterm or LBW infants in hospital and the community.

Methods

We searched nine databases and the reference lists of included studies for eligible studies using qualitative methods examining the views of families on healthcare for preterm or LBW infants. We used the Critical Appraisal Skills Programme checklist for qualitative studies to assess study quality and the GRADE-CERQual approach to assess confidence in each review finding. Studies were sampled after data saturation, and thematic synthesis techniques were used for analysis.

Results

203 studies were eligible for inclusion. We selected 49 studies from 25 countries for the analysis, based on methodological quality, data richness and on ensuring representation from settings with varying resources. Eight analytical themes were identified. Confidence in most results was moderate to high. What mattered to carers was a positive outcome for the child; active involvement in care; support to cope at home after discharge; emotional support for the family; the healthcare environment; their information needs were met; logistical support was available; and positive relationships with staff.

Conclusions

Enabling a positive post-natal period for families of small and sick infants is difficult. Experiences of care for preterm or LBW infants vary, but we found high consistency in what matters to families. This information can be used to shape global recommendations on support for infants and carers. More research is needed on what matters to parents who receive community-based care, especially in low resource settings.

Key messages

• We found high consistency across settings in what matters to families in the care of preterm infants.

• Understanding carers views and values ensures that care can be planned to meet the needs of infants and families.

Sublinear scaling of the cellular proteome with ploidy

Ploidy changes are frequent in nature and contribute to evolution, functional specialization and tumorigenesis. Analysis of model organisms of different ploidies revealed that increased ploidy leads to an increase in cell and nuclear volume, reduced proliferation, metabolic changes, lower fitness, and increased genomic instability, but the underlying mechanisms remain poorly understood. To investigate how gene expression changes with cellular ploidy, we analyzed isogenic series of budding yeasts from 1N to 4N. We show that mRNA and protein abundance scales allometrically with ploidy, with tetraploid cells showing only threefold increase in protein abundance compared to haploids. This ploidy-dependent sublinear scaling occurs via decreased rRNA and ribosomal protein abundance and reduced translation. We demonstrate that the activity of Tor1 is reduced with increasing ploidy, which leads to diminished rRNA gene repression via a Tor1-Sch9-Tup1 signaling pathway. mTORC1 and S6K activity are also reduced in human tetraploid cells and the concomitant increase of the Tup1 homolog Tle1 downregulates the rDNA transcription. Our results suggest that the mTORC1-Sch9/S6K-Tup1/TLE1 pathway ensures proteome remodeling in response to increased ploidy.

Symptom burden and lived experiences of patients, caregivers and healthcare professionals on the management of malignant bowel obstruction: A qualitative systematic review

BACKGROUND

Malignant bowel obstruction occurs in up to 50% of people with advanced ovarian and 15% of people with gastrointestinal cancers. Evaluation and comparison of interventions to manage symptoms are hampered by inconsistent evaluations of efficacy and lack of agreed core outcomes. The patient perspective is rarely incorporated.

AIM

To synthesise the qualitative data regarding patient, caregiver and healthcare professionals' views and experience of malignant bowel obstruction to inform the development of a core outcome set for the evaluation of malignant bowel obstruction.

DESIGN

A qualitative systematic review was conducted, with narrative synthesis. The review protocol was registered prospectively (https://www.crd.york.ac.uk/prospero, CRD42020176393).

DATA SOURCES

MEDLINE, EMBASE, CINAHL, PsycINFO and Scopus databases were searched for studies published between 2010 and 2021. Reference lists were screened for further relevant publications, and citation tracking was performed.

RESULTS

Nine papers were included, reporting on seven studies which described the views and experiences of malignant bowel obstruction through the perspectives of 75 patients, 13 caregivers and 62 healthcare professionals. Themes across the papers included symptom burden, diverse experiences of interventions, impact on patient quality of life, implications and trajectory of malignant bowel obstruction, mixed experience of communication and the importance of realistic goals of care.

CONCLUSION

Some of the most devastating sequelae of malignant bowel obstruction, such as pain and psychological distress, are not included routinely in its clinical or research evaluation. These data will contribute to a wider body of work to ensure the patient and caregiver perspective is recognised in the development of a core outcome set.

Hope and meaning-making in phase 1 oncology trials: a systematic review and thematic synthesis of qualitative evidence on patient-participant experiences

Background

Phase 1 drug trials are popular treatment options for patients with advanced disease, despite the greater levels of uncertainty associated with them. However, their meaning and consequences for patient-participants remains under-explored. This review synthesises the qualitative evidence of patients’ experiences of participating in phase 1 oncology trials, exploring their decisions to take part and the impacts of these trials on patient wellbeing.

Methods

A comprehensive literature search involving medical subject headings (MeSH) and keywords was undertaken in the following databases: MEDLINE, EMBASE, PsycINFO, Scopus, CINAHL, and Cochrane CENTRAL, with supplementary searches also conducted. Studies were independently screened for inclusion by two researchers. Included studies were critically appraised and data extracted using standardised forms. Qualitative results were analysed using thematic synthesis.

Results

Three main themes were identified across 13 studies: decision-making and joining the trial; experiences of taking part in the trial and hope and coping. Patients primarily joined trials hoping for therapeutic benefits, sentiments which prevailed and shaped their experiences across their trial journey. Rather than indicate therapeutic misconception based on poor understanding, patient perspectives more commonly pointed to differences between hope and expectation and cultural narratives of staying positive, trying everything and trusting in experts.

Conclusions

These findings challenge information-based models of consent, favouring coping frameworks which account for the role of hope and meaning-making during serious illness. Personalised consideration of existential and quality-of-life matters before and during trials is recommended, including palliative and supportive care alternatives to active treatment.

End-of-life care for people with severe mental illness: mixed methods systematic review and thematic synthesis of published case studies (the MENLOC study)

OBJECTIVES

People with severe mental illness (SMI) have significant comorbidities and reduced life expectancy. The objective of the review reported in this paper was to synthesise material from case studies relating to the organisation, provision and receipt of care for people with SMI who have an end-of-life (EoL) diagnosis.

DESIGN

Systematic review and thematic synthesis.

DATA SOURCES

MEDLINE, PsycINFO, EMBASE, HMIC, AMED, CINAHL, CENTRAL, ASSIA, DARE and Web of Science from inception to December 2019. Supplementary searching for additional material including grey literature along with 62 organisational websites.

RESULTS

Of the 11 904 citations retrieved, 42 papers reporting 51 case studies were identified and are reported here. Twenty-five of the forty-two case study papers met seven, or more quality criteria, with eight meeting half or less. Attributes of case study subjects included that just over half were men, had a mean age of 55 years, psychotic illnesses dominated and the EoL condition was in most cases a cancer. Analysis generated themes as follows diagnostic delay and overshadowing, decision capacity and dilemmas, medical futility, individuals and their networks, care provision.

CONCLUSIONS

In the absence of high-quality intervention studies, this evidence synthesis indicates that cross disciplinary care is supported within the context of established therapeutic relationships. Attention to potential delay and diagnostic overshadowing is required in care provision. The values and preferences of individuals with severe mental illness experiencing an end-of-life condition should be recognised.

Exploring the association between school-based peer networks and smoking according to socioeconomic status and tobacco control context: a systematic review

BACKGROUND

Whilst prevalence of youth smoking in middle and high income countries has decreased, inequality has prevailed. The introduction of legislation regulating tobacco use in public spaces varies across countries, impacting the tobacco control context. Thus reviewing our knowledge of how social networks may influence smoking differently within different contexts is required to facilitate the development of context-specific interventions.

METHODS

The search, conducted on 31st May 2019, included the following smoking-related terms; schools, adolescents, peers and social networks. Inclusion and exclusion criteria were applied throughout the title and abstract screening and full text screening. Quality assessment and synthesis followed. Studies were narratively synthesised to identify changes according to legislative context. This synthesis was conducted separately for findings relating to three categories: socioeconomic status; social selection and influence; and network position.

RESULTS

Thirty studies were included. Differences in the relationship between network characteristics and smoking according to socioeconomic status were measured in five out of fifteen studies in Europe. Results varied across studies, with differences in network characteristics and their association with smoking varying both between schools of a differing and those of a similar socioeconomic composition. For studies conducted both before and after the introduction of comprehensive smoking legislation, the evidence for selection processes was more consistent than influence, which varied according to reciprocity. Findings showed that isolates were more likely to smoke and in-degree and out-degree centrality were related to smoking both before and after the introduction of legislation. The relationship between popularity and smoking was contingent on school level smoking prevalence in studies conducted before the introduction of legislation, but not after.

CONCLUSIONS

Overall, effects according to socioeconomic status were underreported in the included studies and no consistent evidence of change after the introduction of a comprehensive smoking ban was observed. Further network analyses are required using more recent data to obtain a comprehensive understanding of how network processes may influence smoking differently according to socioeconomic status, and how adaptation could be used to enhance intervention effectiveness.

Site Readiness Framework to Improve Health System Preparedness for a Potential New Alzheimer’s Disease Treatment Paradigm

New therapies that address the underlying pathophysiology of Alzheimer’s Disease (AD), coupled with the growth of the AD population, will transform the AD care pathway and present significant challenges to health systems. We explored real-world challenges health systems may face in delivering potential new AD therapies with diverse stakeholders. Key challenges in care included integrating primary care providers into assessment and management, availability of memory care specialists, understanding payment and coverage issues and training mid-level providers to help coordinate care and serve as a shared resource across the system. This input informed a novel Site Readiness Framework for AD, comprising self-assessment exercises to identify health system capabilities and gaps and a framework of core strategies and responsive tools to help prepare to integrate new AD therapies. These resources may help health systems improve readiness to modify care pathways to integrate new therapies for AD.

End of life care for people with severe mental illness: Mixed methods systematic review and thematic synthesis (the MENLOC study)

BACKGROUND

Parity of esteem means that end-of-life care for people with severe mental illness should be of equal quality to that experienced by all.

AIM

To synthesise international, English language, research and UK policy and guidance relating to the organisation, provision, and receipt of end-of-life care for people with severe mental illness.

DESIGN

A mixed methods systematic review was conducted following the Evidence for Policy and Practice Information and Co-ordinating Centre approach and informed by a stakeholder group. We employed thematic synthesis to bring together data from both qualitative and quantitative studies, and from non-research material. We assessed the strength of synthesised findings using the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approaches.

DATA SOURCES

Ten electronic databases were searched from inception to December 2019, along with 62 organisational websites. Quality appraisal was conducted using Critical Appraisal Skills Programme checklists or other study design-specific alternatives as necessary.

RESULTS

Of the 11,904 citations retrieved, 34 research publications were included plus 28 non-research items. The majority of research was of high or acceptable quality. An overarching synthesis including 52 summary statements, with assessments of confidence in the underpinning evidence, was produced using four themes: Structure of the system; Professional issues; Contexts of care; and Living with severe mental illness.

CONCLUSIONS

Implications for services and practice reflect evidence in which there is a high degree of confidence. Partnership should be developed across the mental health and end-of-life systems, and ways found to support people to die where they choose. Staff caring for people with severe mental illness at the end-of-life need education, support and supervision. End-of-life care for people with severe mental illness requires a team approach, including advocacy. Proactive physical health care for people with severe mental illness is needed to tackle problems of delayed diagnosis.

OS12.7.A Characterization of intra-tumoral heterogeneity and differential immune activation during malignant progression of meningiomas on single cell level

BACKGROUND

As the most common intracranial tumor, meningiomas have caused increasing interest in the field of medical research. Based on their mutational profile, meningiomas can be separated into two main groups: NF2 altered meningiomas, which can occur at WHO grades 1 to 3, and non-NF2 mutant meningiomas with mutations in other genes, such as TRAF7, AKT1, KLF4, and SMO, which are usually of WHO grade 1. While this means that non-NF2 mutant meningiomas usually follow a benign course, risk stratification for NF2 mutant meningiomas remains difficult. As of now, the underlying mechanisms contributing to the malignant phenotype of some NF2 mutant meningiomas remained unknown, even though some molecular markers have been associated with an increased risk of recurrence. Here, we sought to characterize robust molecular subgroups for meningiomas and identify the critical steps in malignant progression of these tumors.

MATERIAL AND METHODS

We applied bulk RNA sequencing and proteomic analyses for 44 meningioma samples as well as single nuclei RNA sequencing analyses for an additional set of 26 meningiomas with a total of 46,002 nuclei. Both datasets comprised samples across the molecular landscape of meningiomas and WHO grades 1, 2, and 3.

RESULTS

The meningioma subgroups previously identified on epigenomic level were found consistently also on transcriptomic, proteomic, and phospho-proteomic levels. In addition, strong differences in numbers and types of infiltrating immune cells between subgroups became apparent. A decreased number of infiltrating macrophages and an activation to a more proinflammatory phenotype was observed for WHO grade 3 tumors. This observation correlated with lower expression levels of CSF1 in tumor cells of WHO grade 3 meningiomas, which was predicted to stimulate macrophages in WHO grade 1 and 2 tumors. Moreover, we identified several tumor cell subpopulations, each defined by a distinct phenotype, shared across samples. Their proportions in the tumor strongly depended on tumor grade. Especially a subpopulation characterized by an elevated stress response and TGFβ signaling activity was found specifically in WHO grade 3 cases.

CONCLUSION

Our findings establish molecular subgroups for meningiomas that are robust across multiple levels with characteristic differences in pathway activities and demonstrate a subtype-specific immune activation, both of which may be basis for novel treatment strategies.

Administration and monitoring of clofazimine for NTM infections in children with and without cystic fibrosis

Few studies have evaluated clofazimine (CLOF) drug monitoring and safety in children. We treated 10 children, 8 with CF, for NTM infection with multiple antimicrobials, including CLOF. All had serial blood CLOF concentrations measured and were followed for adverse events. Despite CLOF dose escalation, most children with CF did not reach a target CLOF concentration. Our data suggest that children with CF may require earlier initiation of CLOF at higher doses than is currently recommended.

Deep muscle-proteomic analysis of freeze-dried human muscle biopsies reveals fiber type-specific adaptations to exercise training

Skeletal muscle conveys several of the health-promoting effects of exercise; yet the underlying mechanisms are not fully elucidated. Studying skeletal muscle is challenging due to its different fiber types and the presence of non-muscle cells. This can be circumvented by isolation of single muscle fibers. Here, we develop a workflow enabling proteomics analysis of pools of isolated muscle fibers from freeze-dried human muscle biopsies. We identify more than 4000 proteins in slow- and fast-twitch muscle fibers. Exercise training alters expression of 237 and 172 proteins in slow- and fast-twitch muscle fibers, respectively. Interestingly, expression levels of secreted proteins and proteins involved in transcription, mitochondrial metabolism, Ca2+ signaling, and fat and glucose metabolism adapts to training in a fiber type-specific manner. Our data provide a resource to elucidate molecular mechanisms underlying muscle function and health, and our workflow allows fiber type-specific proteomic analyses of snap-frozen non-embedded human muscle biopsies.

What elements of a systems' approach to bereavement are most effective in times of mass bereavement? A narrative systematic review with lessons for COVID-19

BACKGROUND

The global COVID-19 pandemic has left health and social care systems facing the challenge of supporting large numbers of bereaved people in difficult and unprecedented social conditions. Previous reviews have not comprehensively synthesised the evidence on the response of health and social care systems to mass bereavement events.

AIM

To synthesise the evidence regarding system-level responses to mass bereavement events, including natural and human-made disasters as well as pandemics, to inform service provision and policy during the COVID-19 pandemic and beyond.

DESIGN

A rapid systematic review was conducted, with narrative synthesis. The review protocol was registered prospectively (www.crd.york.ac.uk/prospero, CRD 42020180723).

DATA SOURCES

MEDLINE, Global Health, PsycINFO and Scopus databases were searched for studies published between 2000 and 2020. Reference lists were screened for further relevant publications, and citation tracking was performed.

RESULTS

Six studies were included reporting on system responses to mass bereavement following human-made and natural disasters, involving a range of individual and group-based support initiatives. Positive impacts were reported, but study quality was generally low and reliant on data from retrospective evaluation designs. Key features of service delivery were identified: a proactive outreach approach, centrally organised but locally delivered interventions, event-specific professional competencies and an emphasis on psycho-educational content.

CONCLUSION

Despite the limitations in the quantity and quality of the evidence base, consistent messages are identified for bereavement support provision during the pandemic. High quality primary studies are needed to ensure service improvement in the current crisis and to guide future disaster response efforts.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Type 1 diabetes mellitus and educational attainment in childhood: a systematic review

OBJECTIVES

The primary objective of this systematic review was to evaluate available literature on whether type 1 diabetes mellitus (T1DM) has an impact on educational attainment in individuals undertaking high stakes standardised testing at the end of compulsory schooling.

DESIGN

A systematic review was undertaken comparing educational attainment for individuals with and without T1DM who have undertaken high stakes testing at the end of compulsory schooling.

DATA SOURCES

A comprehensive search of MEDLINE, MEDLINE (epub ahead of print, in-process and other non-indexed citations), EMBASE, Web of Science, British Education Index, Education Resources Information Center and Cumulative Index to Nursing and Allied Health Literature was undertaken on 15 January 2018 and updated on 17 January 2019.

ELIGIBILITY CRITERIA

Included studies fulfilled the following criteria: observational study or randomised controlled trial; included individuals who have undertaken high stakes testing at the end of compulsory schooling; compared the grades obtained by individuals with T1DM with a representative population control.

DATA EXTRACTION AND SYNTHESIS

Two reviewers performed study selection and data extraction independently. Quality and risk of bias in the observational studies included were assessed using the Newcastle-Ottawa Scale. A detailed narrative synthesis of the included studies was completed.

RESULTS

3103 articles were identified from the database search, with two Swedish cohort studies (using the same linked administrative data) meeting final inclusion criteria. A small but statistically significant difference was reported in mean final grades, with children with T1DM found to have lower mean grades than their non-diabetic counterparts (adjusted mean difference 0.07-0.08).

CONCLUSIONS

More contemporary research is required to evaluate the impact of T1DM in childhood on educational attainment in individuals undertaking high stakes standardised testing at the end of compulsory schooling, taking into consideration the substantial advances in management of T1DM in the last decade.

Palliative Care Evidence Review Service (PaCERS): a knowledge transfer partnership

The importance of linking evidence into practice and policy is recognised as a key pillar of a prudent approach to healthcare; it is of importance to healthcare professionals and decision-makers across the world in every speciality. However, rapid access to evidence to support service redesign, or to change practice at pace, is challenging. This is particularly so in smaller specialties such as Palliative Care, where pressured multidisciplinary clinicians lack time and skill sets to locate and appraise the literature relevant to a particular area. Therefore, we have initiated the Palliative Care Evidence Review Service (PaCERS), a knowledge transfer partnership through which we have developed a clear methodology to conduct evidence reviews to support professionals and other decision-makers working in palliative care.

PaCERS methodology utilises modified systematic review methods as there is no agreed definition or an accepted methodology for conducting rapid reviews. This paper describes the stages involved based on our iterative recent experiences and engagement with stakeholders, who are the potential beneficiaries of the research. Uniquely, we emphasise the process and opportunities of engagement with the clinical workforce and policy-makers throughout the review, from developing and refining the review question at the start through to the importance of demonstrating impact. We are faced with the challenge of the trade-off between the timely transfer of evidence against the risk of impacting on rigour. To address this issue, we try to ensure transparency throughout the review process. Our methodology aligns with key principles of knowledge synthesis in defining a process that is transparent, robust and improving the efficiency and timeliness of the review.

Our reviews are clinically or policy driven and, although we use modified systematic review methods, one of the key differences between published review processes and our review process is in our relationship with the requester. This streamlining approach to synthesising evidence in a timely manner helps to inform decisions faced by clinicians and decision-makers in healthcare settings, supporting, at pace, knowledge transfer and mobilisation.

Associations between school-based peer networks and smoking according to socioeconomic status and tobacco control context: protocol for a mixed method systematic review

BACKGROUND

Smoking remains a major public health concern. School-based social networks influence uptake of smoking among peers. During the past two decades, the UK macro-systemic context within which schools are nested and interact with has changed, with anti-smoking norms having become set at a more macro-systemic level. Whilst the overall prevalence of smoking in the UK has decreased, inequality has prevailed. It is plausible that the influence of school-based social networks on smoking uptake may vary according to socioeconomic status. Therefore, this study aims to understand how social influence on smoking among adolescents has changed in line with variance within and between contexts according to time and geography.

METHODS

The following databases will be searched: Medline, PsycINFO, Embase, Applied Social Sciences Index and Abstracts (ASSIA), British Education Index, Sociological abstracts, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information Center (ERIC) and Scopus. Additional searches will include reference checking of key papers, citation tracking, word of mouth and grey literature searches. The search strategies will incorporate terms relating to smoking, adolescents, schools, peers, network analysis and qualitative research. Titles and abstracts and full texts will be independently screened and assessed for quality by at least two researchers. Included studies will be assessed for quality, and data will be extracted for synthesis, including participant characteristics, setting and tobacco control context, study design and methods, analysis and results and conclusions. Quantitative findings will be narratively synthesised, whilst a lines of argument synthesis combined with refutational analysis will be employed to synthesise qualitative data. Both sets of findings will be charted on a timeline to add context to network findings and obtain an enhanced understanding of changes over time.

DISCUSSION

This protocol is for a mixed methods synthesis of both social network findings, to investigate social structures and qualitative studies, to elicit contextual information. The review will synthesise changes in the context of social influence on adolescent smoking over time and geographically. As context is increasingly recognised as a key source of complexity, this enhanced understanding will help to inform future interventions targeting smoking through social influence. This will help to enhance their relevance to context, subsequent effectiveness and targeting of inequalities.

Optimising paediatric afferent component early warning systems: a hermeneutic systematic literature review and model development

OBJECTIVE

To identify the core components of successful early warning systems for detecting and initiating action in response to clinical deterioration in paediatric inpatients.

METHODS

A hermeneutic systematic literature review informed by translational mobilisation theory and normalisation process theory was used to synthesise 82 studies of paediatric and adult early warning systems and interventions to support the detection of clinical deterioration and escalation of care. This method, which is designed to develop understanding, enabled the development of a propositional model of an optimal afferent component early warning system.

RESULTS

Detecting deterioration and initiating action in response to clinical deterioration in paediatric inpatients involves several challenges, and the potential failure points in early warning systems are well documented. Track and trigger tools (TTT) are commonly used and have value in supporting key mechanisms of action but depend on certain preconditions for successful integration into practice. Several supplementary interventions have been proposed to improve the effectiveness of early warning systems but there is limited evidence to recommend their wider use, due to the weight and quality of the evidence; the extent to which systems are conditioned by the local clinical context; and the need to attend to system component relationships, which do not work in isolation. While it was not possible to make empirical recommendations for practice, the review methodology generated theoretical inferences about the core components of an optimal system for early warning systems. These are presented as a propositional model conceptualised as three subsystems: detection, planning and action.

CONCLUSIONS

There is a growing consensus of the need to think beyond TTTs in improving action to detect and respond to clinical deterioration. Clinical teams wishing to improve early warning systems can use the model to consider systematically the constellation of factors necessary to support detection, planning and action and consider how these arrangements can be implemented in their local context.

The overall metastatic rate in early esophageal adenocarcinoma: long-time follow-up of surgically treated patients

The overall metastatic potential of surgically treated early esophageal adenocarcinoma has not been studied in detail. This paper therefore assessed lymph node metastases at surgery, loco regional and distant metastases, in order to assess the metastatic potential of early esophageal adenocarcinoma. Two hundred and seventeen patients (53 T1a, 164 T1b; median follow-ups 87 and 75 months, 187 males) diagnosed with early esophageal adenocarcinoma and treated with esophagectomy in our tertiary center's database between July 2000 and December 2015 were included. All metastatic events were retrospectively analyzed, their topographic distribution was assessed, and the overall metastatic rate was calculated. Lymph node metastases occurred in 39 patients (18%) and 29 (13.4%) developed recurrences. Lymph node metastases were absent in m1 and m2 tumors and rare in m3 (1/18), m4 (5/21), and sm1 (4/42), but more frequent in sm2 (11/44) and sm3 tumors (18/78). Locoregional recurrences were exceedingly rare in m3 (2/18), m4 (1/21), sm1 (1/42), and sm2 (2/44), but frequent in sm3 (12/78). In contrast, distant metastases were more frequent with 2/18 in m3, 1/21 in m4, 4/42 in sm1, 4/44 in sm2, and 13/78 in sm3. Overall metastatic rates of 11.9% in sm1 (submucosal layer divided into equal thirds), 27.3% in sm2, and 32.1% in sm3 tumors were calculated. This first report of the metastatic potential of early esophageal adenocarcinoma provides a meticulous assessment of the overall metastatic risk. Metastatic events pose a relevant risk in surgically treated patients with esophageal adenocarcinoma with distant metastases being more frequent than locoregional recurrences.

Systematic review of behavioural smoking cessation interventions for older smokers from deprived backgrounds

INTRODUCTION

The associations between smoking prevalence, socioeconomic group and lung cancer outcomes are well established. There is currently limited evidence for how inequalities could be addressed through specific smoking cessation interventions (SCIs) for a lung cancer screening eligible population. This systematic review aims to identify the behavioural elements of SCIs used in older adults from low socioeconomic groups, and to examine their impact on smoking abstinence and psychosocial variables.

METHOD

Systematic searches of Medline, EMBASE, PsychInfo and CINAHL up to November 2018 were conducted. Included studies examined the characteristics of SCIs and their impact on relevant outcomes including smoking abstinence, quit motivation, nicotine dependence, perceived social influence and quit determination. Included studies were restricted to socioeconomically deprived older adults who are at (or approaching) eligibility for lung cancer screening. Narrative data synthesis was conducted.

RESULTS

Eleven studies met the inclusion criteria. Methodological quality was variable, with most studies using self-reported smoking cessation and varying length of follow-up. There were limited data to identify the optimal form of behavioural SCI for the target population. Intense multimodal behavioural counselling that uses incentives and peer facilitators, delivered in a community setting and tailored to individual needs indicated a positive impact on smoking outcomes.

CONCLUSION

Tailored, multimodal behavioural interventions embedded in local communities could potentially support cessation among older, deprived smokers. Further high-quality research is needed to understand the effectiveness of SCIs in the context of lung screening for the target population.

Validity and effectiveness of paediatric early warning systems and track and trigger tools for identifying and reducing clinical deterioration in hospitalised children: a systematic review

OBJECTIVE

To assess (1) how well validated existing paediatric track and trigger tools (PTTT) are for predicting adverse outcomes in hospitalised children, and (2) how effective broader paediatric early warning systems are at reducing adverse outcomes in hospitalised children.

DESIGN

Systematic review.

DATA SOURCES

British Nursing Index, Cumulative Index of Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effectiveness, EMBASE, Health Management Information Centre, Medline, Medline in Process, Scopus and Web of Knowledge searched through May 2018.

ELIGIBILITY CRITERIA

We included (1) papers reporting on the development or validation of a PTTT or (2) the implementation of a broader early warning system in paediatric units (age 0-18 years), where adverse outcome metrics were reported. Several study designs were considered.

DATA EXTRACTION AND SYNTHESIS

Data extraction was conducted by two independent reviewers using template forms. Studies were quality assessed using a modified Downs and Black rating scale.

RESULTS

36 validation studies and 30 effectiveness studies were included, with 27 unique PTTT identified. Validation studies were largely retrospective case-control studies or chart reviews, while effectiveness studies were predominantly uncontrolled before-after studies. Metrics of adverse outcomes varied considerably. Some PTTT demonstrated good diagnostic accuracy in retrospective case-control studies (primarily for predicting paediatric intensive care unit transfers), but positive predictive value was consistently low, suggesting potential for alarm fatigue. A small number of effectiveness studies reported significant decreases in mortality, arrests or code calls, but were limited by methodological concerns. Overall, there was limited evidence of paediatric early warning system interventions leading to reductions in deterioration.

CONCLUSION

There are several fundamental methodological limitations in the PTTT literature, and the predominance of single-site studies carried out in specialist centres greatly limits generalisability. With limited evidence of effectiveness, calls to make PTTT mandatory across all paediatric units are not supported by the evidence base.

Advance care planning for home health staff: a systematic review

BACKGROUND

Advance care planning (ACP) is a process where patients express their wishes regarding their future healthcare. Its importance has been increasingly recognised in the past decade. As increasing numbers of elderly people are living in care homes, the aim of this review was to identify the most effective ACP interventions to train/educate all levels of healthcare professionals working in care homes.

DESIGN

A systematic review. Two independent reviewers undertook screening, data extraction and quality assessment.

DATA SOURCES

 Searched from inception to June 2018: Ovid Medline, Ovid Medline in process, Ovid Embase, Cochrane Central Register of Controlled Trials, EBSCO Cinahl and Ovid PsycINFO.

RESULTS

Six studies were included: three before and after studies, one cluster randomised controlled trial (RCT), one non-blinded RCT and one qualitative study. Five studies reported on ACP documentation, three on impact on ACP practice and three studies on healthcare-related outcomes. All quantitative studies reported an improvement in outcomes. In the three studies reporting on health-related outcomes, one showed significant reductions in hospitalisation rate, days and healthcare costs; one reported significant reductions in hospital deaths; and the third showed reductions in hospital days and deaths. A meta-analysis could not be performed due to the heterogeneity of the outcome measures. The included qualitative study highlighted perceived challenges to implementing an educational programme in the care home setting.

CONCLUSION

There is limited evidence for the effectiveness of ACP training for care home workers. More well-designed studies are needed.

57 Evidence into practice: novel approaches to underpinning evidence-based innovations in care

Background

Developing and implementing novel models of care requires a robust approach to identifying and assessing existing evidence. Rapid reviews have emerged as an efficient approach. There is a growing number of rapid review ‘methods’ but no accepted standardised methodology. We describe the methodological options and an example the Palliative Care Evidence Review Service (PaCERS) where streamlined systematic review methodology is used to conduct rapid reviews requested by clinicians/clinical services.

Aims

To describe evidence synthesis options including PaCERS for producing rapid evidence summaries on questions of direct importance to service delivery. To identify related methodological challenges.

Methods

We examine various rapid review methods and describe in full PaCERS methodology. This uses a focussed search strategy across a limited set of databases and other sources. Study selection data extraction and critical appraisal are performed independently by at least two reviewers. Results are published online using a template co-produced with users which describes key clinical messages evidence quality and summaries of included studies.

Results

We will describe the pros and cons of conducting rapid reviews and highlight methodology development unique to PaCERS. We will discuss specific issues encountered during the review process to produce rigorous reviews in a short time frame for palliative services.

Conclusion

Rapid reviews have tremendous methodological variation however they are an important tool for evidence-informed decision making especially when time resource constraints and health needs are an issue. Therefore using rapid reviews can be used in implementing new models of palliative care.

Association between type 1 diabetes mellitus and educational attainment in childhood: a systematic review protocol

INTRODUCTION

Type 1 diabetes has the potential to significantly impact children's educational attainment. With the increase in incidence, quantifying this effect would be useful to assess how much additional support should be focused on children with type 1 diabetes in school.

METHODS AND ANALYSIS

We will conduct a systematic review of all observational studies and randomised controlled trials, including individuals both with and without a diagnosis of type 1 diabetes who have undertaken high stakes testing at the end of compulsory schooling when under 18 years of age. The search will cover both peer-reviewed and grey literature available from January 2004 to January 2018. The following seven databases will be searched: Ovid MEDLINE (1946 to present), Ovid MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid EMBASE (1947 to present), Thomson Reuters Web of Science, EBSCO Education Resources Information Center, EBSCO British Education Index and EBSCO Cumulative Index to Nursing and Allied Health Literature. Study selection and data extraction will be performed independently by two reviewers with any disagreements resolved via a third reviewer. The quality and risk of bias in the observational studies included in this review will be assessed using the Newcastle-Ottawa Scale. We aim to conduct a meta-analysis and will assess heterogeneity between the included studies and potential for publication bias if sufficient (>10) studies are included.

RESULTS AND DISSEMINATION

Formal ethical approval is not required as individual patient data will not be collected. Results will be disseminated through peer-reviewed publication and conference presentations.

Systematic review of publicity interventions to increase awareness amongst healthcare professionals and the public to promote earlier diagnosis of type 1 diabetes in children and young people

BACKGROUND

Children with new onset type 1 diabetes (T1D) are at risk of developing the life-threatening condition ketoacidosis if they have a delayed diagnosis. The rate of children presenting in ketoacidosis remains high in a number of countries worldwide. To ensure interventions to raise awareness of symptoms are effective a systematic review was conducted to evaluate previous publicity campaigns.

METHODS

A range of databases was searched using search terms relating to T1D, publicity campaigns, and symptom awareness. Identified articles were checked against the inclusion criteria, ensuring interventions were designed to target individuals prior to diagnosis of T1D. Papers were independently assessed under the criteria specified within the Critical Appraisal Skills Programme checklist.

RESULTS

The initial search retrieved 1537 papers and following screening 20 were identified for full consideration. Thirteen did not meet the inclusion criteria, leaving 7 to be assessed. Of these 7, 2 observational case-control studies reported a reduction in the rate of ketoacidosis following a publicity campaign using posters and providing glucose testing equipment to primary healthcare professionals. Four observational cohort studies, utilized posters, and media campaigns; 2 reported a reduction in the rate of ketoacidosis and 2 reported no difference following their interventions. A feasibility study, not designed to evaluate effectiveness, reported some anecdotal evidence of a more timely diagnosis.

CONCLUSION

Due to the methodological limitations of the studies identified, it is not possible to make a definitive conclusion on the effectiveness of the interventions reported.

Plasma Exchange (PE) and Lymphocytapheresis (LCA) in Multiple Sclerosis (MS)

In 96 patients suffering from multiple sclerosis (MS) 277 plasma exchanges (PE) including 176 lymphocytaphereses were performed. Improvement was mainly seen in patients with a short course of disease and at acute exacerbations. Patients with chronic progressive and relapsing intermittent courses responded only poorly. One or two PE were sufficient to induce improvement which was only marginally altered by subsequent PE.

Our data confirm that only selected patients will benefit from PE-treatment especially those with acute exacerbations.

Interventions that enhance health services for parents and infants to improve child development and social and emotional well-being in high-income countries: a systematic review

BACKGROUND

Experiences in the first 1000 days of life have a critical influence on child development and health. Health services that provide support for families need evidence about how best to improve their provision.

METHODS

We systematically reviewed the evidence for interventions in high-income countries to improve child development by enhancing health service contact with parents from the antenatal period to 24 months postpartum. We searched 15 databases and trial registers for studies published in any language between 01 January 1996 and 01 April 2016. We also searched 58 programme or organisation websites and the electronic table of contents of eight journals.

RESULTS

Primary outcomes were motor, cognitive and language development, and social-emotional well-being measured to 39 months of age (to allow the interventions time to produce demonstrable effects). Results were reported using narrative synthesis due to the variation in study populations, intervention design and outcome measurement. 22 of the 12 986 studies identified met eligibility criteria. Using Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group criteria, the quality of evidence overall was moderate to low. There was limited evidence for intervention effectiveness: positive effects were seen in 1/6 studies for motor development, 4/11 for language development, 4/8 for cognitive development and 3/19 for social-emotional well-being. However, most studies showing positive effects were at high/unclear risk of bias, within-study effects were inconsistent and negative effects were also seen. Intervention content and intensity varied greatly, but this was not associated with effectiveness.

CONCLUSIONS

There is insufficient evidence that interventions currently available to enhance health service contacts up to 24 months postpartum are effective for improving child development. There is an urgent need for robust evaluation of existing interventions and to develop and evaluate novel interventions to enhance the offer to all families.

A realist review of one-to-one breastfeeding peer support experiments conducted in developed country settings

The World Health Organisation guidance recommends breastfeeding peer support (BFPS) as part of a strategy to improve breastfeeding rates. In the UK, BFPS is supported by National Institute for Health and Care Excellence guidance and a variety of models are in use. The experimental evidence for BFPS in developed countries is mixed and traditional methods of systematic review are ill-equipped to explore heterogeneity, complexity, and context influences on effectiveness. This review aimed to enhance learning from the experimental evidence base for one-to-one BFPS intervention. Principles of realist review were applied to intervention case studies associated with published experimental studies. The review aimed (a) to explore heterogeneity in theoretical underpinnings and intervention design for one-to-one BFPS intervention; (b) inform design decisions by identifying transferable lessons developed from cross-case comparison of context-mechanism-outcome relationships; and (c) inform evaluation design by identifying context-mechanism-outcome relationships associated with experimental conditions. Findings highlighted poor attention to intervention theory and considerable heterogeneity in BFPS intervention design. Transferable mid-range theories to inform design emerged, which could be grouped into seven categories: (a) congruence with local infant feeding norms, (b) integration with the existing system of health care, (c) overcoming practical and emotional barriers to access, (d) ensuring friendly, competent, and proactive peers, (e) facilitating authentic peer-mother interactions, (f) motivating peers to ensure positive within-intervention amplification, and (g) ensuring positive legacy and maintenance of gains. There is a need to integrate realist principles into evaluation design to improve our understanding of what forms of BFPS work, for whom and under what circumstances.
