Background and study aims
People with dementia (PWD) fall over more often than people who do not have dementia. When they fall over, they are more likely to hurt themselves. They do not get better as easily as people without dementia. After hurting themselves PWD may need a lot more help in looking after themselves. They may need to move to a care home. They and their carer may not have such a good quality of life after the fall. The NHS and social services find it is expensive to look after people with these injuries. We know that injuries cause many problems for PWD, but we do not really know the best way to look after them. This is because there are very few examples of research in this area. Each person is likely to have many different needs, but at the moment, we do not know what these needs are, or how we can meet these needs within the NHS. For instance, would it be better to have a specialist team to look after PWD who fall, or would it be better to invest in education for all staff looking after PWD in the community? We also do not know what is most important to PWD after a fall. For instance, is it more important that they can start walking quickly, or do they need to feel confident that they will not fall again? However we approach this problem, it is important to show that the approach actually works and is good value for money. We do this by carrying out a clinical trial. In this study, we plan to do the background research needed to make sure that we design a trial that has a good chance of being successful.

Who can participate?
People with dementia who live in the community and who have sustained a fall-related injury, and the carers and professionals who care for them.

What does the study involve?
In the first part of the study, the researchers search for previous studies to find out what PWD need after a fall. In the second part of the study, the researchers keep a record of every PWD who sees their GP, calls an ambulance or goes to hospital because they have hurt themselves in a fall in Newcastle, Stockton and Norwich. They check these people’s records to find out if they were kept in hospital or referred to a clinic. They ask some people in each place to keep a detailed diary of all the help they had from the NHS and social services. They then ask if we can interview them and their carers to find out what help they needed after the fall. In the third part of the study, the researchers ask a group of experts, PWD and their carers to look at the things they found out in the first two parts of the study. They ask them whether they think it is likely that they will find enough people to take part in a clinical trial and where it would be best to do it. For example, should they ask the ambulance staff to find the PWD for the trial, or should they do it at the hospital? They ask them about what sort of help people would need and how they should measure whether the PWD got better. In the fourth part of the study, the researchers practice doing the things that the expert group decided they should do. This is with just 15 people in each town and is a practice to smooth out any problems before doing the full trial. The aim is to find out how to cope with any practical problems that would make the trial difficult. They also ask the PWD, their carers and the staff looking after them whether they had any problems taking part.

What are the possible benefits and risks of participating?
At the end of the study, we will be able to say whether it is a good idea to have a full clinical trial of how to improve what happens for PWD who hurt themselves in a fall. If it is, we will be able to recommend how the trial should be done.

Scientific titleIs it possible to develop a complex intervention to improve the outcome of fall-related injuries in people with dementia?
Study acronymDIFRID
Study objectivesThe overall aim of this study is to assess through a series of work packages (WPs) whether it is possible to design a complex intervention to improve the outcome of fall-related injuries in people with dementia living in their own homes.
The health technology to be assessed in this project is a complex intervention and is at the earliest stage of development described in the MRC guidance on developing and evaluating complex interventions. People with dementia who sustain fall-related injuries currently receive a range of health interventions, but a single model of care in the form of a complex intervention for this specific situation has not previously been described and the potential demand for such an intervention is not known. We have taken the approach that in order to develop a new, person-centred and effective complex intervention for this group of patients, we must first be able to answer the following research questions.
1. What are the health and social care needs of patients and carers which must be addressed by the complex intervention?
2. What is the likely demand for the complex intervention?
3. What are the health and social care interventions already being received by patients and carers (i.e., what is usual care)?
4. What are the best available ideas for a new complex intervention (from the perspectives of all stakeholders)?
5. What are the outcomes of importance which the complex intervention must influence (from the perspectives of all stakeholders)?
6. How should changes in these outcomes be measured with respect to clinical effectiveness and cost-effectiveness and have these been measured in any previous studies?

InterventionThis is a feasibility study which aims to design and test the feasibility of a complex intervention

Work package 1: We will use established methods of systematic review to identify empirical evidence regarding the health and social care needs of people with dementia with fall-related injuries, outcomes of importance to patients, carers and professionals and comparative studies providing evidence on the relative effectiveness and cost effectiveness of interventions.

Work package 2: We will use both quantitative and qualitative methods in an observational study, which will describe current models of usual care and identify how the models might be adapted in a complex intervention package.

Work package 3: We will convene a consensus panel to review the findings of the prior work packages. The recommendations of the panel regarding the design of the intervention will be assimilated using methods of the RAND Nominal Group Technique (NGT-R, also known as the modified Delphi panel approach).

Work package 4: We will test the procedures for implementation of the intervention and measurement of outcomes recommended in WP3, in the form of a pre-trial evaluation. We will test the feasibility of delivery of the intervention within present NHS structures, and test acceptability, adherence to delivery of the intervention and outcome measurement.
