Development of a core outcome set for use in research evaluations of interventions for venous leg ulceration: International eDelphi consensus.

INTRODUCTION: Venous leg ulceration (VLU) is a chronic, recurring condition with associated pain, malodour, impaired mobility and susceptibility to infection which in turn significantly impacts an individual's health-related quality of life. Randomised controlled trials (RCTs) aim to determine the efficacy of interventions to improve outcomes. To be useful, these outcomes should be consistently and fully reported across RCTs. A core outcome set (COS) is an agreed-upon standardised set of outcomes which should be, at a minimum, reported in all RCTs for a given indication including that of VLU. AIM: To gain consensus on which outcome domains and outcomes should be considered as core and therefore included in all RCTs of interventions in VLU treatment. METHOD: Two sequential, two round e-Delphi surveys were completed. The first gained consensus on core outcome domains and the second on core outcomes within those domains. Participants included: people with direct experience of having VLUs and their carers, healthcare professionals whose practice included VLU care and researchers within wound care (clinical, academic, industry). RESULTS: Five outcome domains; healing, pain, quality of life, resource use and adverse events, and 11 outcomes were rated as core by participants. The patient and not the limb or ulcer was the preferred unit of analysis for reporting. RECOMMENDATIONS: We recommend investigators report on all five outcome domains, regardless of the type of intervention being evaluated. Future research is needed to identify measurement methods for the 11 identified outcomes. We also recommend investigators follow the CONSORT guidelines (http://www.consort-statement.org/).

Mapping review of pain management programmes and psychological therapies for community-dwelling older people living with pain.

PURPOSE: Persistent pain is common in older people and people living with frailty. Pain or the impact of pain on everyday life is potentially modifiable. We sought to map research evidence and information from randomised controlled trials (RCTs) of pain management programmes and psychological therapies targeting community-dwelling older people, and explore appropriate strategies and interventions for managing or reducing the negative impact of pain for older people, particularly those with frailty. METHOD: A mapping review of pain management programmes and psychological therapies for community-dwelling older people living with chronic pain. We searched for systematic reviews of randomised controlled trials and for individual randomised controlled trials and extracted data from eligible studies. RESULTS: Searches resulted in 3419 systematic review records and 746 RCT records from which there were 33 eligible interventions identified in 31 eligible RCTs (48 reports). Broad aims of the interventions were to: improve physical, psychological, or social functioning; adjust the effects or sensation of pain psychologically; enhance self-care with self-management skills or knowledge. Common mechanisms of change proposed were self-efficacy enhanced by self-management tasks and skills, using positive psychological skills or refocusing attention to improve responses to pain, and practising physical exercises to improve physiological well-being and reduce restrictions from pain. Content of interventions included: skills training and activity management, education, and physical exercise. Interventions were delivered in person or remotely to individuals or in groups, typically in 1-2 sessions weekly over 5-12 weeks. CONCLUSION: All the evaluated interventions appeared to show potential to provide some benefits to older people. None of the included studies assessed frailty. However, some of the included interventions appear appropriate for community-dwelling older people living with both frailty and pain.

Identifying outcomes reported in trials of interventions in venous leg ulceration for a core outcome set development: A scoping review.

BACKGROUND: Venous leg ulceration is a chronic, recurring, condition causing significant patient morbidity. Randomised controlled trials evaluating treatments for venous leg ulceration provide evidence for clinical decision-making. For trial findings to be useful, outcomes measured need to be clinically meaningful, and consistently and fully reported across trials. A core outcome set is an agreed and standardised set of outcomes which should be, as a minimum, reported in all trials for a given indication. AIM: To identify the outcome domains and outcomes reported in trials of interventions for venous leg ulceration. METHODS: A scoping review of the literature was carried out. Randomised controlled trials within Cochrane systematic reviews looking at venous leg ulceration interventions and qualitative studies exploring venous leg ulceration were included. RESULTS: The review identified 807 outcomes from randomised controlled trials and 15 outcomes from qualitative studies, and these were grouped into 11 outcome domains: healing, patient reported symptoms, clinician reported symptoms, carer reported symptoms, life impacts, clinical signs, clinical measurement, performance of the intervention, resource use (supplies and clinician time) and adverse events. The outcome domain 'healing' included 111 outcomes, 'symptoms' 109, 'life impacts' 30, 'clinical signs' 88, 'clinical measurement' 184, 'performance of the intervention' 58, 'resource use' 52 and 'adverse events' 190. CONCLUSION: The scoping review identified a large number of outcomes (n = 822) across 11 related outcome domains, supporting the need for a core outcome set.

Community Ageing Research 75+ (CARE75+) REMOTE study: a remote model of recruitment and assessment of the health, well-being and social circumstances of older people.

INTRODUCTION: The Community Ageing Research 75+ (CARE75+) study is a longitudinal cohort study collecting extensive health and social data, with a focus on frailty, independence and quality of life in older age. CARE75+ was the first international experimental frailty research cohort designed using trial within cohorts (TwiCs) methodology, aligning epidemiological research with clinical trial evaluation of interventions to improve the health and well-being of older people. CARE75+ REMOTE is an extension of CARE75+ using a remote model that does not require face-to-face interactions for data collection in the current circumstances of a global pandemic and will provide an efficient, sustainable data collection model. METHODS AND ANALYSIS: Prospective cohort study using TwiCs. One thousand community-dwelling older people (≥75 years) will be recruited from UK general practices by telephone. Exclusions include: nursing home/care home residents; those with an estimated life expectancy of 3 months or less; and people receiving palliative care. DATA COLLECTION: Assessments will be conducted by telephone, web-submission or postal questionnaire: baseline, 6 months, 12 months, 18 months, 24 months, 30 months and 36 months. Measures include activities of daily living, mood, health-related quality of life, comorbidities, medications, frailty, informal care, healthcare and social care service use. Consent will be sought for data linkage and invitations to additional studies (sub-studies). ETHICS AND DISSEMINATION: CARE75+ was approved by the National Research Ethics Service (NRES) Committee Yorkshire and the Humber-Bradford Leeds 10 October 2014 (14/YH/1120). CARE75+ REMOTE (amendment 13) was approved on the 18th November 2020. Consent is sought if an individual is willing to participate and has capacity to provide informed consent. Consultee assent is sought if an individual lacks capacity. Results will be disseminated in peer-reviewed scientific journals and conferences. Results will be summarised and disseminated to study participants via newsletters, local engagement events and on a bespoke website. TRIAL REGISTRATION NUMBER: ISRCTN16588124.

Development of a core outcome set for venous leg ulceration (CoreVen) research evaluations (protocol).

BACKGROUND: A venous leg ulcer is a chronic leg wound caused by poor venous blood circulation in the lower limbs. It is a recurring condition causing pain, malodour, reduced mobility, and depression. Randomised controlled trials evaluating treatments for venous leg ulcers provide important evidence to inform clinical decision-making. However, for findings to be useful, outcomes need to be clinically meaningful, consistently reported across trials, and fully reported. Research has identified the large number of outcomes reported in venous leg ulcer trials, impacting both synthesis of results, and clinical decision-making. To address this, a core outcome set will be developed. A core outcome set is an agreed standardised set of outcomes which should be, as a minimum, measured and reported in all trials which evaluate treatment effectiveness for a given indication. A core outcome set has the potential to reduce research waste, improve the utility of RCTs, reduce reporting bias, facilitate treatment comparisons across different sources of evidence and expedite the production of systematic reviews, meta-analyses and evidence-based clinical guidelines. AIM: The aim of this project is to develop a core outcome set for research evaluating the effectiveness of interventions for treating venous leg ulceration. METHODS: Through a scoping review of the literature on venous leg ulceration, we will firstly identify a list of candidate outcome domains (broad categories in relation to what is being measured) from randomised controlled trials and qualitative research, and outcomes (specific methods in relation to what is being measured). In two further stages, we will use the resulting lists of outcome domains and outcomes to design two online surveys. A range of stakeholders will be invited to participate in the surveys and they will be asked to indicate which outcome domains and outcomes are most important and should be considered as core in future research reports.
