Plain English Summary

Background and study aims
Frailty is a condition of increased vulnerability to major changes in health as a result of seemingly small problems, such as an infection or new medication. It is common in older age, affecting around 10% of people aged over 65, and develops because as we get older our bodies change and can lose their inbuilt reserves, for example we lose muscle strength. People with frailty are at increased risk of falls, disability, loneliness, hospitalisation and care home admission. These problems can reduce quality of life and are costly for the NHS and social care.
PCP is designed to improve self-management skills and improve wellbeing of older people with the support of their community. It also aims to improve coordination of GP, voluntary sector and social care services and increase the social networks of older people with frailty.
This study aims to test if it is possible to run a large trial to see if PCP can improve the quality of life of older people with frailty and provide value for money.

Who can participate?
People whose GP surgery is taking part in the study and have been identified from their records as someone who would be suitable

What does the study involve?
Researchers will contact all participants and visit them in their homes to ask them to complete questionnaires about general health, quality of life and day-to-day activities. All participants will asked to be complete the same questionnaires 6 and 12 months later.
GP practices will be randomly allocated to either the intervention group or the control group. If participants attend a GP practice in the intervention group, they will be contacted by the Age UK team to take part in a personalised care planning programme. If their GP practice is in the control group, participants will receive care as usual.

What are the possible benefits and risks of participating?
We hope this study could improve quality of life for older people in the future, but cannot say whether they will definitely see an improvement. If participants' GP practice is chosen for the intervention group, they may benefit personally by having a personalised care plan. Participants agreeing to complete questionnaires will mean giving up some of their time to do this.
There are no known risks to participants taking part in this study.

Where is the study run from?
The study is run from the Bradford Teaching Hospitals NHS Foundation Trust and the Clinical Trials Research Unit at the University of Leeds, and will take place in 8 GP practices in Bradford City and District (UK)

When is the study starting and how long is it expected to run for?
October 2017 to December 2020

Who is funding the study?
NIHR Central Commissioning Facility (CCF) (UK)

Who is the main contact?

Frailty in older people


This study is a cluster randomised controlled trial to test the feasibility of conducting a larger scale definitive cluster randomised trial. The PCP intervention will be applied across a whole 'cluster' rather than to individual participants within a general practice. Therefore to allow us to compare the PCP intervention to usual care, we need to randomly assign the whole cluster (GP practice) to either the intervention or control group. We need a control group to help us check that any differences seen are not due to chance.
The study aims to recruit 400 participants from 8 GP practices (approx 50 per practice) within Leeds and Bradford over a planned 12 month recruitment period. Clusters (GP practices) will be randomised on a 1:1 basis by a statistician at the Clinical Trials Research Unit (CTRU).
We will send out expressions of interest (EoI) to all GP surgeries in Leeds and Bradford to ask if they would like further information on the study. Sites (GP practices) expressing an interest will be asked to provide more detailed information by completing a site questionnaire. Suitable sites will be selected by the CI and trial management group (TMG). Consent for randomisation, training, intervention delivery (if allocated) and supporting recruitment will be taken at the practice level.
Potential participants will be identified from pre-defined searches of electronic primary care records based on age (over 65) and electronic Frailty Index (eFI). This eligibility list will be screened by a practice GP to ensure all eligibility criteria are met and the numbers on the list before and after screening recorded.
GP practices will be randomised to the intervention arm or usual care (control) arm and the lead GP at each practice informed of the allocation. Practice staff will send out invitation packs (containing participant & carer invitations and information sheets, reply form and pre-paid envelope) to patients on the eligibility list in a phased approach. If the participant hasn't responded within 14 days, a member of CRN/research staff will contact them by phone to confirm if they wish to participate or not.
A member of the CRN team/local researcher (who will not be aware of the allocated arm) will contact patients who indicated they would like to take part by telephone, to arrange a visit in their home to discuss the study further. If they are still willing to take part, the CRN/local researcher will obtain written informed consent for data collection and linkage and complete a screening test to confirm eligibility to take part. If a participant is confirmed as eligible, the CRN/local researcher will ask some additional questions as part of baseline assessments. The CRN/local researcher will also ask the participant to identify a carer, if available, and obtain consent and collect some baseline assessments from the carer. There may be participants who are not able to consent for themselves. If the CRN/local researcher will assess if this is the case. If they cannot consent themselves, we will endeavour to use a consultee where possible. This could be a close friend or relative of the patient. Baseline data collection will involve the collection of the following demographics, contact details, living and carer arrangements, and questionnaires on healthcare resource use, self-management, health, quality of life, daily living, depression and loneliness. Carers will be asked to complete a questionnaire on quality of life.
For those clusters (practices) randomised to the PCP intervention, participants will be offered a PCP service from a trained Personal Independence Coordination (PIC) team from Age UK. PCP is planned to last for approximately 12 weeks, but this could be from 8 to 16 weeks depending on individual needs. The PIC team will meet with the participant in their own home and also have telephone/email contact.
Those clusters randomised to the control arm of the study will continue to deliver Treatment as Usual to patients.
Data will be collected from each participating site prior to recruitment, approximately halfway through recruitment and at the end of the intervention period to capture; site demographics, staffing and details regarding care offered to these patients. This will allow care in the control (usual care) arm to be described.
All participants and carers (regardless of intervention or control arm) will be sent a questionnaire booklet at 6 months and 12 months following baseline assessment. This data will be self-reported, with participants/carers either completing postal questionnaires, telephone assessments or completing questionnaires with local researcher support, dependent upon the participant's abilities.
Multiple sources of electronic health records will be accessed for this study. Participants will be specifically asked if they consent to allow access to their electronic health records and linkage to study data for this purpose. Data sources include health episodes statistics (HES) and death data from NHS Digital, and primary care data (e.g. medication, contacts) from GP data systems or Connected Health Cities type projects.
To help further understand how the intervention works in practice, researchers will also be observing 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.
