Realist evaluation comparison of dementia-friendly communities in England and Netherlands

IntroductionDementia-friendly communities coordinate activities and events which offer social inclusion and participation of people with dementia. Initiatives can include memory cafés, sports, tourist and heritage visits. This study explored how dementia-friendly initiatives are developed and sustained in England drawing comparisons with an equivalent case-study in the Netherlands. MethodsWe present a case study of dementia-friendly initiatives, of one city in England. Selection of this case study was on the basis of being a leading dementia-friendly community. We interviewed a variety of stakeholders, including people with dementia and their care partners, volunteers and staff. Semi-structured interviews were recorded, and transcripts were analysed using qualitative analysis software using a realist evaluation interpretation. Realist theories described within this English case study were compared with those described within the Dutch cases studies.FindingsFive context mechanism outcome configurations were described. The dementia action alliance for the city was a coordinator of initiatives and provided funding and resources. The alliance facilitated advocates to partner with organisations with a shared commitment to plan activities. On the level of individual interactions, staff or volunteers were involved in communicating with local community members which may lead to improvement in awareness. Initiatives had various ways to listen and incorporate views of people with dementia. The five mechanisms identified within the English case study resonated with mechanisms identified within the larger Dutch case study, with differences in contexts due to local policies and practices.ConclusionStrategic coordination is an important factor for development and sustainability. The national policy in England has set the pattern for local structures, while the Dutch approach is ‘bottom-up’ with local leadership. Community advocates and public support were important factors in development of dementia-friendly initiatives in both countries

Vitamin K supplementation increases vitamin K tissue levels but fails to counteract ectopic calcification in a mouse model for pseudoxanthoma elasticum

Pseudoxanthoma elasticum (PXE) is an autosomal recessive disorder in which calcification of connective tissue leads to pathology in skin, eye and blood vessels. PXE is caused by mutations in ABCC6. High expression of this transporter in the basolateral hepatocyte membrane suggests that it secretes an as-yet elusive factor into the circulation which prevents ectopic calcification. Utilizing our Abcc6−/− mouse model for PXE, we tested the hypothesis that this factor is vitamin K (precursor) (Borst et al. 2008, Cell Cycle). For 3 months, Abcc6−/− and wild-type mice were put on diets containing either the minimum dose of vitamin K required for normal blood coagulation or a dose that was 100 times higher. Vitamin K was supplied as menaquinone-7 (MK-7). Ectopic calcification was monitored in vivo by monthly micro-CT scans of the snout, as the PXE mouse model develops a characteristic connective tissue mineralization at the base of the whiskers. In addition, calcification of kidney arteries was measured by histology. Results show that supplemental MK-7 had no effect on ectopic calcification in Abcc6−/− mice. MK-7 supplementation increased vitamin K levels (in skin, heart and brain) in wild-type and in Abcc6−/− mice. Vitamin K tissue levels did not depend on Abcc6 genotype. In conclusion, dietary MK-7 supplementation increased vitamin K tissue levels in the PXE mouse model but failed to counteract ectopic calcification. Hence, we obtained no support for the hypothesis that Abcc6 transports vitamin K and that PXE can be cured by increasing tissue levels of vitamin K

Dementievriendelijke gemeenschappen: Onderzoek naar succesfactoren van dementievriendelijke initiatieven en -gemeenschappen

Dementievriendelijkheid, wat verstaan we daaronder? Een mooi woord voor de inclusie van mensen met dementie en mantelzorgers in de maatschappij. Op dit moment zijn er in Nederland al 280.000 mensen die leven met dementie. In 2040 is dit aantal naar verwachting verdubbeld naar meer dan een half miljoen. Grote kans dat we er allemaal in meer of mindere mate in onze eigen omgeving mee te maken krijgen. Tijdens het werk, in de familie- of vriendenkring, maar ook in de eigen buurt of de eigen straat

Effects of community occupational therapy on quality of life, mood, and health status in dementia patients and their caregivers: A randomized controlled trial

Background. Cure of dementia is not possible, but quality of life of patients and caregivers can be improved. Our aim is to investigate effects of community occupational therapy on dementia patients' and caregivers' quality of life, mood, and health status and caregivers' sense of control over life. Methods. Community-dwelling patients aged 65 years or older, with mild-to-moderate dementia, and their informal caregivers (n = 135 couples of patients with their caregivers) were randomly assigned to 10 sessions of occupational therapy over 5 weeks or no intervention. Cognitive and behavioral interventions were used to train patients in the use of aids to compensate for cognitive decline and caregivers in coping behaviors and supervision. Outcomes, measured at baseline, 6 weeks, and 12 weeks, were patients' and caregivers' quality of life (Dementia Quality of Life Instrument, Dqol), patients' mood (Cornell Scale for Depression, CSD), caregivers' mood (Center for Epidemiologic Studies Depression Scale, CES-D), patients' and caregivers' health status (General Health Questionnaire, GHQ-12), and caregivers' sense of control over life (Mastery Scale). Results. Improvement on patients' Dqol overall (0.8; 95% confidence interval [CI], 0.6-.1, effect size 1.3) and caregivers' Dqol overall (0.7; 95% CI, 0.5-.9, effect size 1.2) was significantly better in the intervention group as compared to controls. Scores on other outcome measures also improved significantly. This improvement was still significant at 12 weeks. Conclusion. Community occupational therapy should be advocated both for dementia patients and their caregivers, because it improves their mood, quality of life, and health status and caregivers' sense of control over life. Effects were still present at follow-up

Community based occupational therapy for patients with dementia and their care givers: randomised controlled trial

Objective To determine the effectiveness of community based occupational therapy on daily functioning of patients with dementia and the sense of competence of their care givers. Design Single blind randomised controlled trial. Assessors were blinded for treatment allocation. Setting Memory clinic and day clinic of a geriatrics department and participants' homes. Participants 135 patients aged ≥65 with mild to moderate dementia living in the community and their primary care givers. Interventions 10 sessions of occupational therapy over five weeks, including cognitive and behavioural interventions, to train patients in the use of aids to compensate for cognitive decline and care givers in coping behaviours and supervision. Main outcome measures Patients' daily functioning assessed with the assessment of motor and process skills (AMPS) and the performance scale of the interview of deterioration in daily activities in dementia (IDDD). Care giver burden assessed with the sense of competence questionnaire (SCQ). Participants were evaluated at baseline, six weeks, and three months. Results Scores improved significantly relative to baseline in patients and care givers in the intervention group compared with the controls (differences were 1.5 (95% confidence interval 1.3 to 1.7) for the process scale; −11.7 (−13.6 to −9.7) for the performance scale; and (11.0; 9.2 to 12.8) for the competence scale). This improvement was still significant at three months. The number needed to treat to reach a clinically relevant improvement in motor and process skills score was 1.3 (1.2 to 1.4) at six weeks. Effect sizes were 2.5, 2.3, and 1.2, respectively, at six weeks and 2.7, 2.4, and 0.8, respectively, at 12 weeks. Conclusions Occupational therapy improved patients' daily functioning and reduced the burden on the care giver, despite the patients' limited learning ability. Effects were still present at 12 weeks, which justifies implementation of this intervention. Trial registration Clinical Trials NCT00295152
