Dementia research behind the Scenes: Experience of an A-level student in an academic department

guest blogger30 September 2019

We have a fantastic post below from Vennie an A-level student aspiring to study Medicine at university. She visited the Research Department of Primary Care and  and shadowed some of our academics in their various projects in July. In this post talks about her experience and what she took away from it. 

Dementia is an increasing problem especially with the growing older population in the UK. The awareness of dementia is rising, especially through the use of media and organised events such as Memory Walks. However, how much do we know about dementia?

Well, in simple words, dementia is the ongoing decline in the brain. This is only an umbrella term for 200+ different sub-types of dementia that exists, some of which you may have heard off. For example the most common two are Alzheimer’s disease and vascular dementia.

During my placement in the Research Department of Primary Care and Population Health at the Royal Free Hospital, I was able to shadow members of the team that are involved at different levels of research projects.

I discovered that there are many stages which make up the process of a research project. Starting with the planning and design of the research project, ethics, and recruitment through to finally analysing and presenting the results produced. Alongside all this and integrated throughout are processes to ensure the results are implemented into clinical practice and policy, to make a difference. I learnt about the different types of studies such as qualitative studies and large clinical trials. Due to the involvement of human participants including often patients from the NHS in the studies the department runs, a major part of the research process is the ethical application and review. The purpose of the review is to establish if the project has more benefit than risk to the person and their family as well as is the project being conducted sensitively. For all of this to happen, it may take 5 to 20 years to see a difference in practice and policy.

In order for, this project to be successful, a range of people are required to take part, which in turns bring a variety of skills into the mix. These individuals may include designers, programmers, clinicians, psychologists, sociologists, statisticians, qualitative researchers, and importantly patients and their family themselves. A few of the most prominent skills are communication, teamwork, determination and resilience. For example, a project with Dr Davies and Prof Rait I observed on producing a support package for people with dementia and their families, communication has a massive role to play. The project uses workshops with people with dementia, their family and professionals to develop the support package. There is a need for clear communication between the ranges of people for this project to progress smoothly. The communication may come in the form of discussion-based in meetings, emails and many other ways. Therefore, teamwork is essential as each person will have a special role in the project. Finally, determination and resilience are required from every member of the team as there will be challenges along the way, which could be out of your control that must be overcome. For example, if the project does not meet the criteria of the ethics committee it may be returned to the researcher, and his or her team must go back and amend the plan.

In conclusion, research of any kind similar to this project requires a range of people to be involved with a variety of skills that are vital for the research to work. This work experience has been a fascinating and exciting opportunity for me to experience what goes on behind the scenes of a research project.

A comparison of new dementia diagnosis rates across ethnic groups in UK primary care

guest blogger31 August 2018

In this post Tra Pham (UCL Research Department of Primary Care and Population Health) discusses her recent work with colleagues from the department, Division of Psychiatry and King’s College London on new diagnoses of dementia and the differences among ethnic groups.

Around 46.8 million people worldwide have dementia; this is expected to rise to 131.5 million by 2050. Recent studies have reported stable or declining rates of new dementia cases overtime.

In 2010, members of our department (Rait et al, 2010, BMJ) conducted a primary care database study to investigate survival of people with a diagnosis of dementia, and reported a stable rate of new dementia diagnoses in UK primary care between 1990 and 2007. We know little about the differences in the likelihood of receiving a dementia diagnosis among different ethnic groups. Some evidence has indicated that people from Black and Minor Ethnic (BME) groups present at services (i.e. GP) later in their illness. Therefore, compared with the White British ethnic group, BME dementia patients may have less access to timely diagnosis. This can prevent them from benefiting from early intervention and treatment which may help slow the progression of the disease.

Our recent study reported the overall rate of new dementia diagnoses in UK primary care between 2007 and 2015. In addition, we reported, for the first time, the rate by White, Asian, and Black ethnic groups. Pulling together current best evidence of new dementia cases in the community and the 2015 UK census data, we estimated the proportion of White and Black people developing dementia who received a diagnosis in 2015. Our hypothesis was that there would be a smaller proportion of Black people with dementia who were diagnosed compared with people from the White ethnic group.

We analysed data of 2.5 million older people from The Health Improvement Network (THIN) database. 66,083 new cases of dementia were identified, which corresponded to an increased rate of new dementia diagnoses between 2007 and 2015 (Figure 1).

Figure 1 Rate of new dementia diagnoses per 1,000 person-years at risk (PYAR) by calendar year in The Health Improvement Network (THIN) UK primary care database.

Compared with White women, the dementia diagnosis rate was 18% lower among Asian women and 25% higher among Black women. This rate was 28% higher among Black men and 12% lower in Asian men, relative to White men. Based on diagnosis rates in THIN data and projections of new dementia cases from community cohort studies, we estimated that 42% of Black men developing dementia in 2015 were diagnosed, compared with 53% of White men.

The results thus suggest that the rates of people receiving a diagnosis may be lower than the actual rates of developing dementia in certain groups, particularly among Black men. There are several possible explanations for this. It could indicate that Black men experience barriers to accessing health services or receiving a diagnosis. GPs may be more reluctant to diagnose dementia in BME groups especially if culturally competent tests are unavailable. GPs and families might also be reluctant to name dementia in communities where more stigma is associated with a diagnosis.

Our study emphasises the need for service improvement targeting BME groups who might be facing barriers to accessing health care services and getting a dementia diagnosis. GPs should be equipped with culturally appropriate assessment tools in order to make a timely diagnosis of dementia for BME patients.

Our findings also highlight the importance of raising awareness of the benefits of getting a timely diagnosis of dementia, particularly in people from minority ethnic groups who may be more at risk of dementia. Timely diagnosis of dementia can lead to more targeted support and enable GPs to provide appropriate patient care management. These benefits can be explained to the patients by family and friends, as well as professionals such as nurses and social workers. They can also help the patients to overcome the fears of talking about dementia. Faith and community groups can contribute to ensuring that local dementia services are accessible to all.

This study is conducted in collaboration with King’s College London. This work is supported by The Dunhill Medical Trust [grant number R530/1116]. Our article and relevant references can be found at:
