Mealtime difficulty in older people with dementia

Abstract

Aim: To evaluate the evidence published in systematic reviews on the effectiveness of interventions aimed at alleviating mealtime difficulties in older people with dementia. Background: Older people with dementia gradually lose their self-care abilities as the condition of dementia progresses and this includes the ability to eat independently. There is a large body of research into this phenomenon, including into the effectiveness of interventions to alleviate the problems which arise. Recently there have also been several systematic reviews with different conclusions about the effectiveness of these interventions. Design: A systematic review of systematic reviews. Methods: Databases MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsychINFO, Excerpta Medica Database (EMBASE), the Cochrane Library and the Joanna Briggs Library) were searched between January 2005-December 2018 using the search strategy: (feeding OR mealtimes OR eating OR intake OR food and drink OR nutrition OR difficulty) AND dementia AND intervention AND systematic review. The Critical Appraisal Skills Programme (CASP) checklist for Systematic Reviews was used to evaluate the reviews. Results: Eight eligible studies were retrieved; three scored 10 and five scored 8 according to the CASP checklist. Conclusion: The quality of the reviews included in the review were high. There is no strong evidence to support the use of any particular intervention for the alleviation of mealtime difficulties in older people with dementia. Methodological problems related to sample size and bias were apparent in the studies included in all the reviews and there was a lack of standardisation around interventions and outcomes across studies. Behavioural intervention, specifically Montessori education and spaced retrieval methods were considered promising and worthy of further research.
