Background and study aims
Dementia is a common condition in the aging population. People with dementia have difficulties with mental processes such as memory, language, reasoning and identifying people and objects, which become progressively worse over time. Dementia with Lewy Bodies (LBD) and Parkinson’s disease Dementia (PDD) together are known as Lewy Body Dementia (LBD). They share common clinical features and biology, and also respond to similar approaches to management. Currently there is evidence that LBD is often not recognised or managed properly, even in specialist hospital services. The signs and symptoms of LBD can be very hard to detect. Ensuring appropriate management of dementia is central to improving care for patients. At the moment there is no simple tool that includes the full range of LBD symptoms, and no real evidence based management care pathway. Currently there is not enough information to say if any one method used by doctors is better than the others for effective patient management. This study is looking at a newly developed management toolkit, which has been designed to help services to better manage LBD patients. The aim of this study is to compare usual management methods and the new management toolkit in order to evaluate the effect of the toolkit on patient symptoms, outcomes, quality of life and carer stress.
Who can participate?
Patients aged 60 years and over with LBS
What does the study involve?
Participating services are randomly allocated to one of two groups. Services in the first group continue to manage their patients in the usual way, which may vary from service to service. Services in the second group are provided with the management toolkit and encouraged to use this as and when appropriate with all of their patients. The management toolkit is a recommended guideline and can be used according to clinician judgment, either on a single visit or on multiple visits. In both groups, patients and carers attend hour and a half-long visits at the start of the study and then after three and six months. Each visit involves the patient completing a number of questionnaires with a qualified assessor. The carer/informant then seperately completes a number of questionnaires relating to both themselves and the patient.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved to those participating.
Where is the study run from?
21 NHS dementia services in East Anglia and the North East of England (UK)
When is the study starting and how long is it expected to run for?
September 2015 to February 2019

| Scientific title | Improving the diagnosis and management of neurodegenerative dementia of Lewy body type in the NHS. Work Package 5A and 5B: A pilot cluster randomised study of the management toolkit in the NHS secondary care services |
| Study acronym | DIAMOND-Lewy |
| Study objectives | The aim of this study is to see if a newly developed management toolkit will result in symptom improvement, increased quality of life and decreased carer stress in patients with Lewy Body Dementia (LBD). |
| Ethics approval(s) | West Midlands – Coventry and Warwickshire REC, 17/02/2016, ref: 16/WM/0025 |
| Health condition(s) or problem(s) studied | Specialty: Dementias and neurodegeneration, Primary sub-specialty: Dementia; UKCRC code/ Disease: Neurological/ Other degenerative diseases of the nervous system |
| Intervention | Services are randomised to receive either the management toolkit (interventional sites) or to continue their usual management of the patients (control sites). The management toolkit is a recommended guideline and will be used according to clinician judgment in the intervention arm. It could be used at a single visit only, or over multiple visits/patient contacts across several months. The management toolkit will be used as part of routine practice and will remain with sites after the end of the study. Additional study visits will be conducted at baseline, 3 months and 6 months, and clinicians in the intervention arm will be asked to complete a clinician toolkit use questionnaire. The patient and carer will take part in 3 visits (baseline, 3 and 6 months) which will take place at their home over a 6 month period. Each visit will take approximately 1 hour 30 minutes. Each visit involves the patient completing a number of questionnaires with a qualified assessor. The carer/informant will separately complete a number of questionnaires relating to both themselves and the patient. If both the patient and carer can be present, 2 members of the team will conduct the visit when possible. The final study visit will be done at 6 months (+/- 2 weeks) after the baseline visit. This will be the end of the study for patients and carers/informants. |
| Intervention type | Other |
| Primary outcome measure | 1. Feasibility of use of the intervention is assessed by Clinician Toolkit Feedback Questionnaire at approximately 6 months after service has been randomised and at the end of the trial. 2. Impact of the assessment and management toolkit on patient management, health outcomes, and its impact on informants/carers is assessed by this is assessed through collection of outcome measured at baseline, 3 and 6 months 3. Cost-effectiveness of the new assessment and management toolkit for LBD with usual care is assessed by this is assessed by the Use of services and costs Questionnaire at Baseline, 3 months and 6 months and Time and Travel Questionnaire at 6 months as listed below |
| Secondary outcome measures | 1. Symptom severity is measured using the reduced Neuropsychiatric Inventory (NPI) score; lower unified Parkinson’s disease rating scale (UPDS) score; Dementia Cognitive Fluctuation Scale (DCFS-R), lower Cornell depression score, Galvin Lewy Body Composite Score and Geriatric Depression Scale at baseline, 3 and 6 months 2. Patient quality of life is measured using the patient EQ-5D-5L and carer proxy EQ-5D-5L; patient DEMQOL and carer DEMQOL-proxy scales at baseline, 3 and 6 months 3. Rates of cognitive decline is measured using the MMSE and MoCA scales at baseline, 3 and 6 months 4. Carer stress and quality of life is measured using the carer EQ-5D-5L; HADS; and Zarit burden scale at baseline, 3 and 6 months 5. Global outcome is measured using the Global outcome Scale at 3 months and 6months. 6. Heath economic measures are measured using the non-standardised questionnaires developed by the research team as follows: Time and Travel Questionnaire at 6 months and Use of services and costs Questionnaire at Baseline, 3 months and 6 months |
