Plain English Summary

Background and study aims
Frailty can be a distressing but not inevitable part of getting older. People who are frail may feel more tired and weak than normal, have trouble getting around, lose weight and feel that they are slowing down. Frailty progresses over a period of 5-15 years and may lead to losing independence, hospital admissions and moving to a care home.
Previous research has suggested that it may be possible to support older people to manage frailty like any other long-term condition. If recognised early, care and support can be provided that may delay or prevent negative effects of frailty so that older people can retain their independence and quality of life. To do this, people need effective support at home from health services such as their GP, community and practice nurses.
Once people are aged 80 years and over, between a quarter and a half will show some of the signs of frailty. Therefore, it is important that we understand the causes and how best to manage the condition for the future. Like many long-term conditions, frailty cannot be cured, so we need to understand how to empower people to live well with it.
This research aims to explore how people can be best supported at home and how community nurses could work to provide individualised support. We want to explore if we can improve outcomes for patients enabling them to live at home, improve wellbeing, prevent falls and reduce the need for unplanned hospital care.

Who can participate?
Adults aged 65 years or older who have moderate or severe frailty and live in their own home or in supported living accomodation

What does the study involve?
The first part of the study will include a survey of an expert group of nurses to explore their views of elements of care for frail older people in the community. This will enable development of a care plan based on the individual needs of people that can be used by nurses in partnership with patients and their carers. In the second part of the study, a small trial will be undertaken to test this new care plan, including frailty assessment and evaluation, to see if it is practical and achievable. In this part of the study, there will be a group of patients who receive the new care plan and a group who will receive care as usual.
In the final part of the study, the experiences of participating in the trial will be explored with frail patients, carers and nurses. The information gathered during the proposed project will be used to inform a future larger clinical trial to ensure the methods we used are fit for purpose.

What are the possible benefits and risks of participating?
Participants in intervention group may benefit from visits and support from a nurse in addition to your normal care and support; however, we cannot guarantee any specific benefits from this. Participating in research does deliver wider benefits to society and others with a similar condition and will help us to determine how best to support people in the future.
There are no known risks to participants taking part in this study. Participants will be asked to give up some of their time to participate in the study, which may be inconvenient.

Where is the study run from?
Cornwall Partnership NHS Foundation Trust and 6 other practices in Cornwall, UK

When is the study starting and how long is it expected to run for?
May 2018 to April 2021

Scientific title

The Holistic Assessment and care Planning in Partnership Intervention (HAPPI) Study: A cluster randomised, controlled feasibility study of a nurse-led, holistic assessment and care planning intervention for older people living with frailty in primary care



Study hypothesis

There is no formal hypothesis as this is a feasibility study. The primary aim of this cluster randomised, controlled feasibility study of a nurse-led Holistic Assessment and care Planning in Partnership Intervention (HAPPI) is to determine the feasibility of delivering the intervention in primary care to older people with frailty and to test potential trial methods to inform the design of a definitive randomised controlled trial (RCT).

Frailty in older people


We aim to recruit 60 participants from general practices in Cornwall. Cluster randomisation will be used. Half of the general practices will be allocated to the intervention and half to the control arm of the study, so that patients of individual practices will either receive the intervention or usual primary care. Community Matrons (CMs) in the area under study will deliver the intervention. They are attached to specific general practices and so individual CMs would only visit participants in the control or the intervention group, never both. As the HAPPI is an intervention that aims to impact on staff skills, knowledge and clinical practice, it is important to ensure separation of the control and intervention groups in this way.

Once informed consent or consultee agreement has been received, baseline assessment of outcome measures will be undertaken with the participants. All baseline assessments will be carried out in one session and at the same time as consent is obtained to minimise burden of multiple contacts for participants. They will be undertaken by the CI or authorised delegate (RAs). Consent and baseline outcome measures will be collected in the participant’s place of residence and it is estimated that this consent and data collection visit will be approximately 60 minutes duration. Support and additional time/visit will be offered to participants who may need suffer fatigue, cognitive impairment etc. As a feasibility study, any difficulties will be noted and adjustment made to the design of the main trial.
The assessor will record the results of the baseline assessments on the case report form (CRF) and enter the results into a secure password protected web-based system. This will generate an email for the community matron who will be carrying out the intervention informing that he/she can contact the participant and arrange the first visit in accordance with the intervention guide.

Participants in the intervention group will receive the HAPPI intervention delivered by a CM who has received training in delivering the intervention. In Cornwall, CMs are experienced nurses with advanced assessment and prescribing skills and, therefore have the required skills set to deliver the assessment and care planning intervention. CMs are attached to individual general practices and employed by the community services NHS Trust (Cornwall Foundation NHS Trust). In order to ensure a standardised approach, training will be given prior to delivering the intervention using a training package delivered by face-to-face training by the CI.
The holistic assessment and care planning intervention (HAPPI) will encompass the following key principles that make the intervention unique and different to current care for this population:
1. The person will not be referred in crisis (as in current CM practice) but will be approached proactively following identification using the eFI and PRISMA7 screening tool.
2. The CM will visit without first gaining any past medical history or other information about the person’s health from the general practice record and initiate an “unbiased, open dialogue” with the person. Any issues/problems/deficits will be generated from this dialogue and the assessment and care-planning intervention will develop from this point.
3. There will be an ongoing development and review of a support plan in partnership with the person and carer (if appropriate).
4. Outcome measures will focus on responsiveness to change/completeness of the intervention and discharge plans; what is different after the intervention is complete.
5. The intervention will be based on a “conversation guide” rather than a prescriptive assessment template. Assessment tools will be available to be used if they are appropriate for that person’s needs/problems.
A conversation guide, assessment pack and personalised support plan template have been developed to support delivery of the intervention and ensure treatment fidelity by detailing the content of the intervention and how it should be delivered. The intervention will be carried out in the participant’s home and it is expected that it will consist of one assessment visit and up to six care planning visits conducted over a maximum of 12 weeks. For the purpose of the trial, the minimum “dose” of the intervention will be defined as one assessment visit and at least two care planning visits. Documentation of the intervention, including assessment, support plan and evidence of any referrals, will be recorded using a standardised document/computerised template, which will be stored at in the clinical record at the Community Matron’s base with a copy in the electronic general practice clinical record.

Participants in the control group will receive usual care. This cannot be standardised as approaches to care of older people with frailty varies in general practice. This may include the management of various long-term conditions, referrals to other services, prescribing of medications and routine vaccinations. As part of the feasibility trial, components of usual care will be captured in order to standardise for the future definitive RCT using a standardised template.

All potential clinician and self-reported primary and secondary outcome measures will be collected at baseline (following randomisation), three months (post intervention) and six months. As a feasibility trial, process evaluation is a key part of the intervention development process to enable conclusions to be drawn about the strengths and weaknesses of a trial.

This study also has an embedded qualitative component. This component of the trial explores the experiences of the study participants, their carers and the experiences of the clinicians who have delivered the intervention and GP practice staff who facilitated recruitment and eligibility screening. The aim is to generate recommendations and address unknowns including experiences of recruitment, retention, practical implementation and further refinement of the intervention and outcome measures for the design of the future randomised controlled trial.
In-depth semi-structured interviews will be undertaken by the CI, which will last approximately 40 minutes. An interview protocol and topic guide will comprise questions relating to structure, process and outcome of the trial. The topic guide will not be exhaustive, with flexibility to offer space and the opportunity for participants to raise other issues which they might consider pertinent. All interviews will be audio recorded for their entire duration and transcribed verbatim by the CI or delegated staff. Interviews for patients and carers will be conducted at the patient’s own home following an informal format, which it is envisaged will assist in creating a situation in which experiences will be openly shared, without participants fearing they are being too critical. Interviews for the community matrons will be conducted at their local work base or other CFT premises. All respondents will be assured of the anonymity of the data and that the interviews are intended to be non-judgemental.
In particular, the CMs will be asked to describe, discuss and elaborate on the situations they found interesting and challenging with regard to implementation of the HAPPI intervention with patients, and the situations they found interesting and challenging with regard to delivery of the HAPPI intervention e.g. any operational difficulties within the community matron service.
The GPs will be asked to describe the situations they found interesting and challenging with regard to the identification, screening and recruitment procedures.
In particular, the participants will be asked to describe, discuss and elaborate on the situations that they found interesting and challenging with regard to receiving the HAPPI intervention or usual care, the situation that they found interesting and challenging with regard to the completion of each of the questionnaires and the experience of participating in the trial
