How nurses can support the inclusion in research of older people who lack capacity to consent

Effective interventions to increase representation of under-served groups in randomised trials in UK and Ireland: a scoping literature review

Background

Participants in clinical trials often do not reflect the populations that could benefit from the treatments being investigated. There are known barriers to trial participation for under-served groups, but limited evidence on strategies to alleviate these barriers to improve representation. This scoping review aimed to identify effective interventions and design features that improve the representation `of under-served groups in trials, focusing on the UK and Ireland.

Methods

We included methodological research studies that reported interventions to improve representation of ethnic minority groups, socioeconomically disadvantaged groups, older people, or those with impaired capacity to consent to randomised controlled trials, conducted in the UK and Ireland, published between 2000-2021. Systematic searches were conducted in November 2021 and data were independently extracted by two authors and narratively synthesised.

Results

Seven studies were included: one randomised controlled study embedded in five trials, one mixed-methods study, and five studies reporting 'lessons learnt' from one trial. We categorised the 47 reported interventions or strategies into nine broad themes: Recruitment sites, recruitment settings, community engagement, and communication with participants, incentives, inclusion criteria, flexibility, patient documentation, and the consent process. Only 28/47 interventions were evaluated, 23 of which were comparison of recruitment pathways.The randomised study found that a £100 incentive mentioned in the invitation letter increased positive responses overall across drug trials in cardiovascular disease and hypertension, but not for older people or those living in the most deprived areas. Invitation letters via GPs and working with communities were reported as successful recruitment pathways in recruiting different under-served populations.

Conclusions

Interventions aiming to improve the recruitment of under-served groups in the UK and Ireland were reported across seven papers, but their effectiveness was rarely rigorously evaluated. Included studies were context specific. Using a variety of recruitment methods is likely to help achieve a more diverse cohort.

Pragmatic Trials in Long-Term Care: Research Challenges and Potential Solutions in Relation to Key Areas of Care

As a method of research, pragmatic trials are recommended so as to generate results that are applicable to real-world care. This intent is especially important for the millions of older adults who receive long-term care in thousands of nursing homes and assisted living communities across the country-and many millions more around the globe. This article presents key points raised by experts participating in a conference funded by the National Institute of Aging held at the 2021 conference of the Society for Post-Acute and Long-term Care Medicine. The purpose of the conference was to convene leading clinicians, researchers, and industry partners to address special considerations of pragmatic trials in long-term care. Cross-cutting and unique challenges and solutions to conducting pragmatic trials were discussed focusing on 3 areas of clinical relevance to long-term care: (1) functional care and outcomes, (2) psychosocial care and quality of life, and (3) medical care and outcomes, with a special focus on persons with dementia. Challenges and innovative solutions were organized across the 9 domains of the revised Pragmatic-Explanatory Continuum Indicator Summary (PRECIS) Tool, and future research recommendations for pragmatic trials in long-term care were identified.
