Design outcomes

Primary

MeasureTime frame
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

MeasureTime frame
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
