[Effectiveness of interventions to strengthen cognitive resources in nursing home residents : A systematic review and network meta-analysis]
Abstract
Background: Strengthening cognitive resources of residents in nursing homes is an important goal of preventive activities. The aim of this systematic review was to answer the question which intervention is most effective for nursing home residents to strengthen their cognitive resources.
Method: A systematic literature search was carried out in the Cochrane Library and the MEDLINE (PubMed), Embase, CINAHL, PsycINFO and PEDro databases. Reference lists of publications classified as relevant were checked and trial registries were searched. The literature selection, data extraction and assessment of the study quality were carried out by two reviewers independently. A frequentist network meta-analysis was conducted using a random effects model.
Results: A total of 29 studies with 1816 participants were included. Both physical activity (standardized mean difference [SMD] = 0.70, 95%-confidence interval [CI] 0.35-1.06, p < 0.001) and cognitive activity (SMD = 0.61, 95%-CI 0.22-1.01, p < 0.01) were statistically significantly superior in strengthening cognitive resources compared to usual care. Physical and cognitive activities did not differ statistically significantly from each other. In addition, neither physical activity nor cognitive activity showed statistically significantly better cognitive resources in nursing home residents compared to social activities.
Conclusion: The findings imply that physical activity as well as cognitive activity could be effective to strengthen cognitive resources of nursing home residents. Considering the low-quality of available evidence, performance of high-quality studies is essential in order to verify the robustness of the statistical results.
