This evidence theme on mealtime care is a summary of one of the key topics identified by a scoping review of dementia research. If you need more information on this topic, try using the PubMed search below.
Several types of interventions have been trialled to try to improve people’s mealtime experiences. These have mainly focused on increasing food and drink intake to prevent weight loss, dehydration, and malnutrition with its associated problems. These interventions can be grouped into:
- Educational and training interventions for people with dementia, their family carers, nurses, and care workers
- Mealtime assistance from nurses and care workers
- Changes to the dining room environment or food service.
No reviews reported potentially effective interventions to support healthy fluid intake. [3]
Education and training interventions
Montessori-based methods have shown some success in helping people with dementia to complete mealtime tasks, avoiding frustration and the risk of weight loss and malnutrition. [4-9] These methods may also increase the frequency with which people feed themselves without assistance. [9, 10] With this approach, an instructor breaks down eating tasks into small steps, demonstrating each in sequence while using simple language and visual clues to encourage the person with dementia to follow. Food intake might be improved further by adding ‘spaced retrieval’ to these activities. [10] Spaced retrieval is a technique for increasing memory retrieval. It consists of giving eating-related procedural information to people with dementia and asking them to recall this information at increasing time intervals. [11] As Montessori activities and spaced retrieval need to be repeated over weeks, they require a high level of staff time and training. [1] At this time, the findings may not be conclusive enough to justify the large financial investments that would be required to introduce these approaches. [8, 9]
Online or face-to-face feeding skills training programs for family carers, nurses, and care workers are shown to increase carer knowledge of feeding difficulties and ways to manage them. [9] Although findings varied as to whether they lead to longer mealtimes for people with dementia, more opportunities to try self-feeding or reduced feeding difficulties. [9, 11] Carer training programs do not appear to lead to increased food intake or beneficial weight gain for people with dementia. [1, 13] In fact, several studies show that eating difficulties increase with greater care worker knowledge. This might be due to increased staff ability through education to better assess the mealtime experience. [8]
Mealtime assistance
One-on-one care worker assistance to people with dementia at mealtimes is shown to effectively improve the food intake of people with dementia to a small extent. [1, 9] This assistance can be in the form of verbal prompts, positive reinforcement, and encouragement to continue with eating tasks and hand feeding. [9, 10, 13] Different types of hand feeding assistance techniques were found to have different degrees of benefit. The Over Hand technique, whereby the care worker places their hand on top of the resident’s hand holding cutlery, to help them guide the food to their mouth, had greater benefit than Under Hand or Direct Hand techniques. [9] However, the approach substantially increases the care worker’s time spent at the dining table during mealtimes. [11]
Changes to the dining room environment and food service
There is some weak evidence that suggests simple changes to the dining room environment, or the way food is served can lead to benefits for people with dementia. Changes showing a positive impact on food/drink intake include:
- Playing background music during mealtimes to encourage people to stay longer at the table, to communicate with other residents [14], and to reduce responsive behaviours [15]
- Shared mealtimes between staff and residents [16]
- Using strongly coloured tableware that contrasts with a white tablecloth to help people see their food [17, 18]
- Allowing people with dementia to serve themselves, rather than receiving a pre-prepared plate of food [19]
- Introducing well-lit aquariums with a viewing area at eye level [20]
- Employing a multicomponent intervention, involving: preparation of residents, environment, food and utensils; appropriate mealtime assistance; psychological care; and post-meal nursing care was reported as significantly improving feeding behaviours. [9]
