Effects of oral nutrition supplements in persons with dementia: A systematic review.

OBJECTIVE: Persons with dementia are at risk of malnutrition, evidenced by low dietary intake, which has consequences for nutritional status, activity of daily living and disease progression. The effects of oral nutrition supplements (ONS) on nutritional intake, nutritional status, and cognitive and physical outcomes in older persons with dementia were evaluated. METHODS: PubMed, Medline, Embase, CINAHL and the Cochrane Central Register of Controlled Trials were searched in December 2017, and this was repeated in May 2019. The Preferred Reporting Items for Systematic Reviews and Analysis (PRISMA) checklist was used. Papers were considered if they presented experimental clinical trials using oral nutritional supplements to persons diagnosed with dementia, including Alzheimer's disease and mild cognitive impairment, and conducted in hospitals, nursing homes or homes. RESULTS: We included ten articles reporting nine clinical trials. A total of 407 persons with dementia were included, of whom 228 used ONS for 7 to 180 days. Nutritional intake improved by 201 to 600 kcal/day. Energy intake from ordinary foods was not affected, thus ONS improved the persons daily intake of energy and protein. Body weight, muscle mass, and nutritional biomarkers in blood improved in the intervention groups compared with the control groups. No effects on cognition or physical outcomes were observed. CONCLUSION: ONS increases the intake of energy and protein and improves nutritional status in persons with dementia; however, RCTs with longer intervention periods are needed to investigate the impact on cognitive and functional outcomes.

The compound role of a coordinator for home-dwelling persons with dementia and their informal caregivers: qualitative study.

BACKGROUND: As the number of persons with dementia is increasing, there has been a call for establishing sustainable clinical pathways for coordinating care and support for this group. The LIVE@Home.Path trial is a multicomponent, multi-disciplinary intervention combining learning, innovation, volunteer support and empowerment. To implement the intervention, a municipal coordinator has a crucial role. Implementation research on multicomponent interventions is complex and we conducted a qualitative study, aiming to explore the coordinator role and how a coordinator may empower persons with dementia in decision-making processes. METHODS: Qualitative program evaluation combined with a hermeneutic interpretive approach was chosen as methodological approach. Sixteen dyads, consisting of the person with dementia and their main informal caregiver received the intervention by two coordinators. Of these, six dyads, three informal caregivers alone and the two care coordinators along with their leader, in sum, eighteen persons, participated in in-depth or focus group interviews, sharing their experiences after 6 months intervention. RESULTS: We found that the coordinators fulfilled three functions for the participating dyads: being a safety net, meaning that the dyads might have little needs at the moment, but found safety in a relation to someone who might help if the situation should change; being a pathfinder, meaning that they supported the dyads in finding their way through the complicated system of care and support services; being a source for emotional care and support, meaning that they listened, acknowledged and gave counsel in times of distress. The coordinators emphasized that a trusting leader and work environment was crucial for them to fulfill these functions. We also found that it was challenging for the coordinators to build a relation to the persons with dementia in order to pursue genuine empowerment in decision-making processes. CONCLUSION: We found the framework for follow-up to be a feasible starting point for establishing empowering coordination and a sustainable care pathway for persons with dementia and their informal caregivers. More meeting points between coordinator and person with dementia should be pursued in order to fulfill the persons' fundamental rights to participate in decision-making processes.
