Policy continues to emphasise the importance of wellbeing in dementia. However, there is a vital need for psychosocial interventions that can promote positive outcomes to enhance “living well with dementia”. Our developing understanding of what people living with dementia report as being important to them, has resulted in new interpretations of what constitutes wellbeing including constructs such as “growth”, “purpose” and “participation”. These exciting and important constructs are not currently captured by outcome measures within dementia research. This limits our understanding of the value of psychosocial interventions. This paper explores the concept of participation and how continued participation in social life can make a difference to the rights of people living with dementia as citizens. We will firstly consider why participation is important for how we might measure outcomes in dementia research and care. Secondly, we will explore how we might measure participation. Finally, we will consider the value of participation as a psychosocial outcome in future research.

Background There is an urgent clinical need for evidence based psychosocial interventions for people with mild dementia. We aimed to determine clinical and cost-effectiveness of Journeying through Dementia (JtD), an intervention designed to promote wellbeing and independence in people with mild dementia. Methods We conducted a phase 3, two-arm parallel group, superiority, individually randomised controlled trial. Thirteen NHS sites across England recruited community-dwelling people with mild dementia and Mini-Mental State Examination score of ≥18. Centralised randomisation (1:1) was conducted for participants to receive JtD plus usual care or usual care (control), stratified by site. The JtD Intervention comprised 12 group and four one-to-one sessions, delivered in the community at each site. The primary endpoint was Dementia Related Quality of Life (DEMQOL), eight-months postrandomisation. Only outcome assessors were blinded. Analysis was by intention-to-treat. Costeffectiveness analysis reported cost per quality adjusted life year (QALY) from a UK NHS and social care perspective. Findings In total 480 people were randomised to intervention (241) or control (239) arms. Intervention adherence was very good. Mean DEMQOL scores at eight months were intervention arm 93·3 (SD 13·0, n=191) and control 91·9 (SD 14·6, n=197). Difference in means was 0·9 (95% CI -1·2 to 3·0) after adjustment for covariates, lower than that identified as clinically meaningful. Incremental cost per QALY ranged from £88K to -£205K, indicating that JtD was not cost-effective. Unrelated serious adverse events were experienced by 17% (40/241) of intervention and 15% (35/239) of control participants. Interpretation In common with other recently reported studies the JtD intervention was not provenly effective. However, this complex trial successfully recruited and retained people with dementia without necessarily involving carers, and people with dementia they were actively involved as participants and study advisors throughout. Further research into methods of measuring small, meaningful changes in this population is needed. Questions remain regarding how services can match the complex, diverse and individual needs of people with mild dementia, and how interventions to meet such needs can be delivered at scale.

This is a poster presented at the 6th International Clinical Trials Methodology Conference (ICTMC 2022). It summarises work conducted to elicit minimum important differences in DEMQOL and DEMQOL-U, two dementia specific quality of life outcome measures.

Objectives To determine the clinical and cost effectiveness of a multifactorial fall prevention programme compared with usual care in long term care homes. Design Multicentre, parallel, cluster randomised controlled trial. Setting Long term care homes in the UK, registered to care for older people or those with dementia. Participants 1657 consenting residents and 84 care homes. 39 were randomised to the intervention group and 45 were randomised to usual care. Interventions Guide to Action for Care Homes (GtACH): a multifactorial fall prevention programme or usual care. Main outcome measures Primary outcome measure was fall rate at 91-180 days after randomisation. The economic evaluation measured health related quality of life using quality adjusted life years (QALYs) derived from the five domain five level version of the EuroQoL index (EQ-5D-5L) or proxy version (EQ-5D-5L-P) and the Dementia Quality of Life utility measure (DEMQOL-U), which were self-completed by competent residents and by a care home staff member proxy (DEMQOL-P-U) for all residents (in case the ability to complete changed during the study) until 12 months after randomisation. Secondary outcome measures were falls at 1-90, 181-270, and 271-360 days after randomisation, Barthel index score, and the Physical Activity Measure-Residential Care Homes (PAM-RC) score at 91, 180, 270, and 360 days after randomisation. Results Mean age of residents was 85 years. 32% were men. GtACH training was delivered to 1051/1480 staff (71%). Primary outcome data were available for 630 participants in the GtACH group and 712 in the usual care group. The unadjusted incidence rate ratio for falls between 91 and 180 days was 0.57 (95% confidence interval 0.45 to 0.71, P
