Plain English Summary

Background and study aims
Frailty is a condition that affects one in ten people over the age of 65 and can mean they are at higher risk of falls, disability, hospital and care home admission and poorer quality of life. As the population ages, frailty also impacts on health and social care services. Care for older adults should be proactive and person-centred rather than focused on different diseases and personalised care planning or PCP is one way to deliver person-centred care. Researchers have developed a PCP intervention called PROSPER that aims to improve the quality of life of older adults with frailty and also reduce the burden on health and social care systems.

Who can participate?
People aged 65 or older and identified as having some signs of frailty by their GP records

What does the study involve?
A researcher will visit participants in their own home to describe the trial and answer any questions. If people are happy to take part the researchers will ask them to fill in some questionnaires about their quality of life. Participants will then be randomly divided into two groups – intervention and usual care. Participants in the intervention group will be contacted by a Personal Independence Coordinator from Age UK who will work with them for 12 weeks to help improve their wellbeing and self-management skills. Participants in the usual care group will carry on as normal. Everyone will be asked to complete the questionnaires again at 6 and 12 months after they started the study.

What are the possible benefits and risks of participating?
Participants in the intervention group may experience improved physical and mental health.

Where is the study run from?
The study is run by researchers from the Academic Unit of Ageing & Stroke Research at the Bradford Institute for Health Research and the Clinical Trials Research Unit at the University of Leeds

When is the study starting and how long is it expected to run for?
September 2019 to March 2023

Who is funding the study?
National Institute for Health Research Programme Grant for Applied Research (UK)

Older people with frailty


The study is a multi-centre, individually randomised trial with clustering in the intervention arm. The researchers will aim to recruit 1337 older people with frailty from general practices across five localities in England over a period of 15 months. Potential participants will be identified by practice staff from primary care records according to pre-defined inclusion and exclusion criteria using bespoke electronic searches. Practice staff will send a letter of invitation for trial participation along with a participant information sheet to all eligible participants identified through the search. Participants will be requested to indicate their willingness to be involved in the study via a reply form returned via post to the research teams or via telephone. The local research team will visit willing participants at their own home to seek written informed consent and collection of baseline data.

Following consent and baseline data collection, an automated system will be used to randomly allocated to participants to either the usual care or PROSPER intervention. The PROSPER intervention is a 12-week tailored intervention delivered within a participant’s home by a trained Age UK delivery team around an individual’s personal priorities and predicaments within a socially-orientated model of care. Age UK workers will deliver the intervention to several participants and therefore the study has a partially nested hierarchical design resulting in clustering within the intervention arm.

As part of the study, the researchers will define usual care as “the wide range of care that is provided in a community whether it is adequate or not, without a normative judgement”, and will be available to all study participants including those in the intervention arm. To increase external validity and relevance of the study findings the researchers plan to use an unrestricted usual care approach, whereby the protocol does not restrict access to usual care. Use of services will be recorded at baseline and at follow-up assessments in both intervention and control arms.

To help further understand the implementation of the intervention and usual care, researchers will also be observing the delivery of the intervention, and performing interviews with staff, participants, and their carers in a sample of willing participants. This is called an embedded process evaluation.

Follow-up data will be collected from all participants at 6 and 12 months following randomisation. This data will be self-reported, with participants either completing postal questionnaires, telephone assessments, or completing questionnaires with researcher support, dependent upon the participant’s abilities. Researchers will also collect additional data regarding the participant’s safety (e.g. hospital admissions), and health and social care resource use (i.e. primary/secondary care) from the participant's electronic health records. Researchers collecting follow-up data will be unaware of the participant's allocation (blind) and will be asked to document if they become aware of the participant's allocation during the study.

Drug names

Primary outcome measure

Health-related quality of life measured using the Physical Component Summary (PCS) and Mental Component Summary (MCS) of the Short-Form 12 item Health Questionnaire (SF12) at 12 months post-randomisation

Secondary outcome measures

1. Basic and instrumental activities of daily living, measured using the Nottingham Extended Activities of Daily Living Scale (NEADL) at 12 months post-randomisation
2. Admissions to care homes and overall health and social care resource use, measured by participant-reported and routine data derived resource use at 12 months post-randomisation
3. Cost-effectiveness measured using decision analytical cost-effectiveness model at 12 months post-randomisation
4. Generalisability of PCP across the wider NHS measured using a mixed-methods process evaluation at 3 months post-randomisation:
4.1. Assessment of intervention fidelity by examining training & skill acquisition, intervention delivery, content of care sessions, receipt and enactment using observations, qualitative interviews and quantitative data
4.2. Process of implementation within the service context explored using a combination of qualitative observations, semi-structured interviews and documentary analysis
