Feeding and hydration issues for older adults with dementia

A 'personhood paradox': Care partners' experiences supporting people with dementia and incontinence

Globally, 50 million people live with dementia and mostly receive care at home. Urinary, faecal and functional incontinence is common in this population and increases care demands. This study explores care partners' experiences managing continence care for people with dementia in Aotearoa New Zealand. The data are drawn from a cross-sectional qualitative study with 18 care partners of people with dementia and incontinence in mid and northern regions of Aotearoa New Zealand. Participants were interviewed face-to-face from June 2022 to April 2023. Data were analysed using Interpretive Phenomenological Analysis. Six Generalised Experiential Themes emerged. Care partners engaged in autobiographical and biographical meaning-making to interpret behaviours and maintain the personhood of people with dementia, focusing on dignity, identity, and social inclusion. However, caregiving often undermined care partners' personhood due to the physical and emotional demands of continence care. Access to resources was challenging, and healthcare support was often perceived as inadequate. Some care partners' strategies to find meaning and joy in everyday life contributed to resilience, while others experienced stress, fatigue, and burnout. Care partners used personal knowledge to support personhood, especially in social engagement. Uncertainty in managing incontinence led to self-doubt, exacerbated by the medicalised nature of continence care, which involves intimate attention beyond typical caregiving. Timely, credible advice could reduce uncertainty, but many found seeking resources overwhelming. Balancing their own well-being with caregiving highlights the need for support systems addressing the requirements of both care partners and people with dementia.

Presbyphagia: Dysphagia in the elderly

Dysphagia has been classified as a “geriatric syndrome” and can lead to serious complications that result in a tremendous burden on population health and healthcare resources worldwide. A characteristic age-related change in swallowing is defined as “presbyphagia.” Medical imaging has shown some changes that seriously affect the safety and efficacy of swallowing. However, there is a general lack of awareness of the effects of aging on swallowing function and a belief that these changes are part of normal aging. Our review provides an overview of presbyphagia, which has been a neglected health problem for a long time. Attention and awareness of dysphagia in the elderly population should be strengthened, and targeted intervention measures should be actively implemented.

Does Hydration Status Influence Executive Function? A Systematic Review

BACKGROUND

Cognitive function, including executive function (EF)-related capacities (eg, working memory, inhibitory and attentional control), has been linked to adherence to healthy lifestyle behaviors. Dehydration is associated with impaired cognitive function, whereas improvements in hydration status may improve inhibitory and attentional performance. No systematic reviews have examined the effects of both dehydration and euhydration on EF.

OBJECTIVE

The objectives of this systematic review are to examine studies that have investigated the spectrum of hydration status and EF in adults, and to identify future research needs.

DESIGN

The review was conducted according to the 2015 Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. The database search was initially conducted on May 12, 2019 and then updated on April 26, 2020. Databases searched included PubMed, Medline, Psyc Info, SCOPUS, Proquest, and ISI Web of Science. Data extraction included the following: method used to assess de/hydration status, study design, participant characteristics, EF tasks and domain, and results. Article quality ratings were performed on included studies using the Academy of Nutrition and Dietetics Quality Rating Checklist.

PARTICIPANTS/SETTING

Studies done with healthy or diseased adults, aged older than 18 years, in any setting, were included. Studies of individuals with disease states that impact fluid balance or require fluid restrictions as treatments were excluded.

MAIN OUTCOME MEASURE

All EF-related outcomes were included, such as working memory, inhibitory control, task switching, and attention.

RESULTS

Four thousand eight hundred thirty-three articles were screened using title/abstracts. Seventy-one full-text articles were assessed for eligibility; 33 were included (26 included investigations of dehydration; 27 included investigations of rehydration/euhydration) with 3,636 participants across all studies. Little consistency was found across outcomes. Roughly half of the available studies suggested unclear or neutral EF effects, and half suggested effects on EF domains, particularly working memory, inhibitory control, and attention. Studies including a euhydration condition were slightly more likely to demonstrate improvements to EF capacities.

CONCLUSIONS

Overall, there is a strong need for consistent methodological approaches and a greater number of long-term (ie, >3 days) studies of dehydration and euhydration and EF.

Namaste care in the home setting: developing initial realist explanatory theories and uncovering unintended outcomes

INTRODUCTION

The End-of-Life Namaste Care Program for People with Dementia, challenges the misconception that people with dementia are a 'shell'; it provides a holistic approach using the five senses, which can provide positive ways of communicating and emotional responses. It is proposed Namaste Care can improve communication and the relationships families and friends have with the person with dementia. Previously used in care homes, this study is the first to explore the pioneering use of Namaste Care in people's own homes.

OBJECTIVE

To develop initial programme theories detailing if, how and under which circumstances Namaste Care works when implemented at home.

DESIGN

A qualitative realist approach following the RAMESES II guidelines was employed to understand not only whether Namaste Care has positive outcomes, but also how these are generated, for whom they happen and in which circumstances.

SETTING

A hospice in the North East of England, operating in the community, through volunteers.

PARTICIPANTS

Programme theories were developed from three focus groups with volunteers implementing Namaste Care (n=8; n=8; n=11) and eight interviews with family carers (n=8).

RESULTS

Four refined explanatory theories are presented: increasing engagement, respite for family carers, importance of matched volunteers and increasing social interaction. It was identified that while Namaste Care achieved some of the same goals in the home setting as it does in the care home setting, it could also function in a different way that promoted socialisation.

CONCLUSIONS

Namaste Care provides holistic and personalised care to people with both moderate and advanced dementia, improving engagement and reducing social isolation. In the present study carers often chose to use Namaste Care sessions as respite. This was often linked to their frustration of the unavoidable dominance of task-focussed care in daily life. Individualised Namaste Care activities thus led to positive outcomes for both those with dementia and their carers.

Management of Dehydration in Patients Suffering Swallowing Difficulties

Swallowing difficulties, also called dysphagia, can have various causes and may occur at many points in the swallowing process. The treatment and rehabilitation of dysphagia represent a major interdisciplinary and multiprofessional challenge. In dysphagic patients, dehydration is frequent and often accelerated as a result of limited fluid intake. This condition results from loss of water from the intracellular space, disturbing the normal levels of electrolytes and fluid interfering with metabolic processes and body functions. Dehydration is associated with increased morbidity and mortality rates. Dysphagic patients at risk of dehydration thus require close monitoring of their hydration state, and existing imbalances should be addressed quickly. This review gives an overview on dehydration, as well as its pathophysiology, risk factors, and clinical signs/symptoms in general. Available management strategies of dehydration are presented for oral, enteral, and parenteral fluid replacement.

Feeding behaviors among incident cases of schizophrenia in a psychiatric hospital: Association with dimensions of psychopathology and social support

BACKGROUND

Despite early description by Eugen Bleuler of abnormal feeding behaviors among patients with schizophrenia, it has remained poorly studied and understood by clinicians. The present study sought to describe the various eating behaviors among incident cases of schizophrenia and its relationship with the dimensions of psychopathology and perceived social support.

METHODS

This study elicited information on the feeding behavior of 206 incident cases of schizophrenia being followed up for various nutritional outcomes. Feeding behavior, dimensions of psychopathology and perceived social support were measured using literature based researchers' constructed nutritional questions, Positive and Negative Symptoms Scale (PANSS), and Multi-dimensional Scale of Perceived Social Support (MSPSS), respectively. Relationship between food refusal and dimensions of psychopathology as well as perceived social support were tested using independent t-test.

RESULTS

Food refusal was seen in 56.5% of the patients, with 32.5% of it attributed to suspiciousness. Of the 13.2% with Inappropriate feeding behavior, 46.4% and 14.3% were related to abnormal food preparation and pica, respectively. Food refusal was significantly associated with positive symptoms dimension and general psychopathology (p < 0.05).

CONCLUSION

Our findings show that subtle feeding abnormalities occur among schizophrenia patients and this is related to positive symptoms dimension and poor perceived social support.

Environmental and behavioural modifications for improving food and fluid intake in people with dementia

BACKGROUND

Weight loss, malnutrition and dehydration are common problems for people with dementia. Environmental modifications such as, change of routine, context or ambience at mealtimes, or behavioural modifications, such as education or training of people with dementia or caregivers, may be considered to try to improve food and fluid intake and nutritional status of people with dementia.

OBJECTIVES

Primary: To assess the effects of environmental or behavioural modifications on food and fluid intake and nutritional status in people with dementia. Secondary: To assess the effects of environmental or behavioural modifications in connection with nutrition on mealtime behaviour, cognitive and functional outcomes and quality of life, in specific settings (i.e. home care, residential care and nursing home care) for different stages of dementia. To assess the adverse consequences or effects of the included interventions.

SEARCH METHODS

We searched the Specialized Register of Cochrane Dementia and Cognitive Improvement (ALOIS), MEDLINE, Eembase, PsycINFO, CINAHL, ClinicalTrials.gov and the World Health Organization (WHO) portal/ICTRP on 17 January 2018. We scanned reference lists of other reviews and of included articles.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) investigating interventions designed to modify the mealtime environment of people with dementia, to modify the mealtime behaviour of people with dementia or their caregivers, or both, with the intention of improving food and fluid intake. We included people with any common dementia subtype.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, extracted data and assessed the risk of bias of included trials. We assessed the quality of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We included nine studies, investigating 1502 people. Three studies explicitly investigated participants with Alzheimer's disease; six did not specify the type of dementia. Five studies provided clear measures to identify the severity of dementia at baseline, and overall very mild to severe stages were covered. The interventions and outcome measures were diverse. The overall quality of evidence was mainly low to very low.One study implemented environmental as well as behavioural modifications by providing additional food items between meals and personal encouragement to consume them. The control group received no intervention. Differences between groups were very small and the quality of the evidence from this study was very low, so we are very uncertain of any effect of this intervention.The remaining eight studies implemented behavioural modifications.Three studies provided nutritional education and nutrition promotion programmes. Control groups did not receive these programmes. After 12 months, the intervention group showed slightly higher protein intake per day (mean difference (MD) 0.11 g/kg, 95% confidence interval (CI) -0.01 to 0.23; n = 78, 1 study; low-quality evidence), but there was no clear evidence of a difference in nutritional status assessed with body mass index (BMI) (MD -0.26 kg/m² favouring control, 95% CI -0.70 to 0.19; n = 734, 2 studies; moderate-quality evidence), body weight (MD -1.60 kg favouring control, 95% CI -3.47 to 0.27; n = 656, 1 study; moderate-quality evidence), or score on Mini Nutritional Assessment (MNA) (MD -0.10 favouring control, 95% CI -0.67 to 0.47; n = 656, 1 study; low-quality evidence). After six months, the intervention group in one study had slightly lower BMI (MD -1.79 kg/m² favouring control, 95% CI -1.28 to -2.30; n = 52, 1 study; moderate-quality evidence) and body weight (MD -8.11 kg favouring control, 95% CI -2.06 to -12.56; n = 52, 1 study; moderate-quality evidence). This type of intervention may have a small positive effect on food intake, but little or no effect, or a negative effect, on nutritional status.Two studies compared self-feeding skills training programmes. In one study, the control group received no training and in the other study the control group received a different self-feeding skills training programme. For both comparisons the quality of the evidence was very low and we are very uncertain whether these interventions have any effect.One study investigated general training of nurses to impart knowledge on how to feed people with dementia and improve attitudes towards people with dementia. Again, the quality of the evidence was very low so that we cannot be certain of any effect.Two studies investigated vocal or tactile positive feedback provided by caregivers while feeding participants. After three weeks, the intervention group showed an increase in calories consumed per meal (MD 200 kcal, 95% CI 119.81 to 280.19; n = 42, 1 study; low-quality evidence) and protein consumed per meal (MD 15g, 95% CI 7.74 to 22.26; n = 42, 1 study; low-quality evidence). This intervention may increase the intake of food and liquids slightly; nutritional status was not assessed.

AUTHORS' CONCLUSIONS

Due to the quantity and quality of the evidence currently available, we cannot identify any specific environmental or behavioural modifications for improving food and fluid intake in people with dementia.

Exploring residents' experiences of mealtimes in care homes: A qualitative interview study

Background

Many interventions aim to alleviate well-documented problems of malnutrition in residential care homes and improve residents’ health and wellbeing. Despite some positive findings, little is known about how and why mealtime interventions might be effective, and in particular, what effects residents’ experiences of mealtimes have on health outcomes. The aim of this study was to gain an insight into these experiences and explore some of the issues that may impact on residents’ enjoyment of meals, and resulting health and wellbeing.

Methods

Semi-structured interviews were conducted with eleven residents from four care homes in the South West UK. Thematic analysis was used to derive content and meaning from transcribed interviews. Interviews were supplemented by researcher observations of mealtimes.

Results

The dining experience was a focal point for participants’ broader experiences of residing in a care home. Three themes pertaining to residents’ experiences were identified: (1) Emotional and psychological connections with other residents; (2) managing competing interests with limited resources; and (3) familiarity and routine.

Conclusion

Mealtimes are a mainstay of life in a care home through which residents’ experiences are characterised, exemplified and magnified. Understanding how residents interact with one another, accommodating their preferences and encouraging autonomy may enhance their mealtime experiences. It may also help to ease the transition from independent-living to life in care, which can be particularly stressful for some residents, and improve health and wellbeing over the long-term.

Prevalence and factors associated with food intake difficulties among residents with dementia

Background

Few studies have examined the prevalence of food intake difficulties and their associated factors among residents with dementia in long-term care facilities in Taiwan. The purpose of the study was to identify the best cutoff point for the Chinese Feeding Difficulty Index (Ch-FDI), which evaluates the prevalence of food intake difficulties and recognizes factors associated with eating behaviors in residents with dementia.

Methods and findings

A cross-sectional design was adopted. In total, 213 residents with dementia in long-term care facilities in Taiwan were recruited and participated in this study. The prevalence rate of food intake difficulties as measured by the Chinese Feeding Difficulty Index (Ch-FDI) was 44.6%. Factors associated with food intake difficulties during lunch were the duration of institutionalization (beta = 0.176), the level of activities of daily living-feeding (ADL-Q1) (beta = -0.235), and the length of the eating time (beta = 0.416). Associated factors during dinner were the illuminance level (beta = -0.204), sound volume level (beta = 0.187), ADL-Q1 (beta = -0.177), and eating time (beta = 0.395).

Conclusions

Food intake difficulties may potentially be associated with multiple factors including physical function and the dining environment according to the 45% prevalence rate among dementia residents in long-term care facilities.

Tube Feeding Patients With Dementia

As the population ages, the incidence of dementia increases. All types of dementia, whether they are reversible or irreversible, lead to loss of intellectual function and judgment, memory impairment, and personality changes. The skills to feed oneself, use eating utensils, and consume items recognized as food, thereby maintaining nutrition status, may be lost as dementia progresses. Reports indicate that nutrition status may be maintained when patients are hand fed, but this is labor intensive and therefore expensive. Feeding via a percutaneous endoscopic gastrostomy tube is often chosen as an acceptable alternative. Research indicates that there is little benefit in this population when aggressive nutrition support is instituted. Providing tube feeding to patients with dementia does not necessarily extend life, increase weight, or reduce the incidence of pressure ulcers or aspiration. There are many legal and ethical issues involved in the decision to place a feeding tube in demented patients. The primary issue in patients with dementia may be autonomy and the right of an individual to decide whether or not a tube should be placed at all. Legally, there is clear precedent that the courts see the insertion of a feeding tube as extraordinary care that the patient has the right to refuse. However, much of case law is derived from cases of patients who were in a persistent vegetative state. Advance directives help to determine what the patient would want for himself. Considering all the options before the patient can no longer make decisions is the most desirable course.

Who cares?

The complexity of the relationship between intellectual disability (ID) and dementia is increasingly acknowledged. In order to operationalize a route towards person-centred care, we introduce the hierarchy model (Pearce, 1999) as a tool to focus the attention of policy and practice on all aspects of caregiving. This tool, which is taken from the family therapy literature, enables practitioners to examine the broad systems that impact on the delivery and receipt of care. In this article, we focus on its utility in scrutinizing end-of-life and later stages of dementia by illustrating its use with three key areas in dementia care. These three areas provide some of the most challenging situations at the end stages, because of the possible treatment options, they are: nutrition, medical interventions, and the location of care provision. This model enables a focused approach to understanding how meaning is created within social interaction. The article draws out implications for practice and policy and has applications for practice internationally.

The effect of environmental change on residents with dementia

This qualitative study aimed to identify and describe the relatives' and staff's perceptions of environmental change on residents with dementia. Data were collected from audio-taped relative and staff focus group interviews at an aged care facility in Western Sydney. The transcribed data from the focus groups were thematically analysed and categorized. Three major categories emerged from the analysed data: the special care unit as a family home, therapeutic environment and work environment. Relatives and staff identified that the overall design of the unit impacted on the residents' functioning and quality of life, sense of freedom, level of agitation, sleeping patterns and weight. Relatives reported that the environment was conducive to visiting and to children, and staff reported that the working environment was improved because of its layout and equipment. This study has shown that special care units can make a difference to the quality of life of residents and improve conditions for relatives and staff.

Effectiveness of interventions to indirectly support food and drink intake in people with dementia: Eating and Drinking Well IN dementiA (EDWINA) systematic review

Background

Risks and prevalence of malnutrition and dehydration are high in older people but even higher in older people with dementia. In the EDWINA (Eating and Drinking Well IN dementiA) systematic review we aimed to assess effectiveness of interventions aiming to improve, maintain or facilitate food/drink intake indirectly, through food service or dining environment modification, education, exercise or behavioural interventions in people with cognitive impairment or dementia (across all settings, levels of care and support, types and degrees of dementia).

Methods

We comprehensively searched Medline and twelve further databases, plus bibliographies, for intervention studies with ≥3 cognitively impaired adult participants (any type/stage). The review was conducted with service user input in accordance with Cochrane Collaboration’s guidelines. We duplicated assessment of inclusion, data extraction, and validity assessment, tabulating data. Meta-analysis (statistical pooling) was not appropriate so data were tabulated and synthesised narratively.

Results

We included 56 interventions (reported in 51 studies). Studies were small and there were no clearly effective, or clearly ineffective, interventions. Promising interventions included: eating meals with care-givers, family style meals, soothing mealtime music, constantly accessible snacks and longer mealtimes, education and support for formal and informal care-givers, spaced retrieval and Montessori activities, facilitated breakfast clubs, multisensory exercise and multicomponent interventions.

Conclusions

We found no definitive evidence on effectiveness, or lack of effectiveness, of specific interventions but studies were small and short term. A variety of promising indirect interventions need to be tested in large, high-quality RCTs, and may be approaches that people with dementia and their formal or informal care-givers would wish to try.

Trial registration

The systematic review protocol was registered (CRD42014007611) and is published, with the full MEDLINE search strategy, on Prospero (http://www.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42014007611).

The Effects of Age and Preoral Sensorimotor Cues on Anticipatory Mouth Movement During Swallowing

PURPOSE

The aim of this study was to investigate the effects of preoral sensorimotor cues on anticipatory swallowing/eating-related mouth movements in older and younger adults. It was hypothesized that these cues are essential to timing anticipatory oral motor patterns, and these movements are delayed in older as compared with younger adults.

METHOD

Using a 2 × 2 repeated-measures design, eating-related lip, jaw, and hand movements were recorded from 24 healthy older (ages 70-85 years) and 24 healthy younger (ages 18-30 years) adults under 4 conditions: typical self-feeding, typical assisted feeding (proprioceptive loss), sensory-loss self-feeding (auditory and visual loss/degradation), and sensory-loss assisted feeding (loss/degradation of all cues).

RESULTS

All participants demonstrated anticipatory mouth opening. The absence of proprioception delayed lip-lowering onset, and sensory loss more negatively affected offset. Given at least 1 preoral sensorimotor cue, older adults initiated movement earlier than younger adults.

CONCLUSIONS

Preoral sensorimotor information influences anticipatory swallowing/eating-related mouth movements, highlighting the importance of these cues. Earlier movement in older adults may be a compensation, facilitating safe swallowing given other age-related declines. Further research is needed to determine if the negative impact of cue removal may be further exacerbated in a nonhealthy system (e.g., presence of dysphagia or disease), potentially increasing swallowing- and eating-related risks.

ESPEN guidelines on nutrition in dementia

BACKGROUND

Older people suffering from dementia are at increased risk of malnutrition due to various nutritional problems, and the question arises which interventions are effective in maintaining adequate nutritional intake and nutritional status in the course of the disease. It is of further interest whether supplementation of energy and/or specific nutrients is able to prevent further cognitive decline or even correct cognitive impairment, and in which situations artificial nutritional support is justified.

OBJECTIVE

It is the purpose of these guidelines to cover these issues with evidence-based recommendations.

METHODS

The guidelines were developed by an international multidisciplinary working group in accordance with officially accepted standards. The GRADE system was used for assigning strength of evidence. Recommendations were discussed, submitted to Delphi rounds and accepted in an online survey among ESPEN members.

RESULTS

26 recommendations for nutritional care of older persons with dementia are given. In every person with dementia, screening for malnutrition and close monitoring of body weight are recommended. In all stages of the disease, oral nutrition may be supported by provision of adequate, attractive food in a pleasant environment, by adequate nursing support and elimination of potential causes of malnutrition. Supplementation of single nutrients is not recommended unless there is a sign of deficiency. Oral nutritional supplements are recommended to improve nutritional status but not to correct cognitive impairment or prevent cognitive decline. Artificial nutrition is suggested in patients with mild or moderate dementia for a limited period of time to overcome a crisis situation with markedly insufficient oral intake, if low nutritional intake is predominantly caused by a potentially reversible condition, but not in patients with severe dementia or in the terminal phase of life.

CONCLUSION

Nutritional care and support should be an integral part of dementia management. In all stages of the disease, the decision for or against nutritional interventions should be made on an individual basis after carefully balancing expected benefit and potential burden, taking the (assumed) patient will and general prognosis into account.

A qualitative study of professional caregivers' perceptions of processes contributing to mealtime agitation in persons with dementia in nursing home wards and strategies to attain calmness

Aim

Describe professional caregivers' perceptions of factors and processes contributing to mealtime agitation and strategies for attaining and maintaining calm mealtimes.

Design

Qualitative and descriptive.

Methods

A convenience sample of professional caregivers working in two wards for residents with dementia was used. Data were collected during two focus‐group interviews and supplemented with field notes from six reflection groups. Thematic content analysis was conducted. Data collection occurred from 2010–2011.

Results

Professional caregivers perceived agitation during mealtime as resulting from negative feelings in residents triggered by a lack of or negative social interaction, too much or ambiguous stimuli or demands exceeding residents' capacity. Strategies for attaining calm mealtimes involved thorough planning beforehand. During mealtime, professional caregivers focused on establishing a positive community around the table, helping residents focus on eating and continuously observing residents for subtle signals indicating that agitation was about to develop. The prerequisites to succeed with the strategies were knowledge of the residents' preferences and abilities, knowledge sharing within the team and awareness of one's own communication style. Thus, the professional caregivers operationalized person‐centred care in a mealtime context.

Development and Psychometric Evaluation of the Chinese Feeding Difficulty Index (Ch-FDI) for People with Dementia

Aims

To develop and evaluate the psychometric properties of a Chinese Feeding Difficulty Index (Ch-FDI) which assesses feeding difficulties in people with dementia (PwD).

Research Design and Method

Scale items were developed using literature review based on Model of Feeding Difficulty. Content validity was evaluated and items were modified by expert panel. Following translation and back-translation, the Ch-FDI was piloted on residents with dementia. The reliability was tested by inter-rater reliability and test-retest reliability. Internal reliability was established by calculating Cronbach's α coefficient. The concurrent validity was evaluated by correlating with similar scale, the Edinburgh Feeding Evaluation in Dementia (EdFED). The exploratory factor analysis (EFA) with varimax rotation and parallel analysis (PA) was performed to test construct validity.

Method

Participants were recruited from long-term care facilities in Taiwan. A total of 213 residents with dementia participated in this study during May, 2010 to February, 2011.

Results

Content validation, translation and psychometric testing were completed on the 19 items of the Ch-FDI. The translated scale was piloted on 213 residents with dementia of feeding difficulty who were recruited from eight long-term care facilities in Taiwan. The reliability was supported by the internal consistency of Cronbach's α of 0.68 and a test-retest coefficient of 0.85. The content validity, face validity, concurrent validity, and construct validity were used.

Conclusions

The Ch-FDI is a newly developed scale with fair psychometric properties aimed to measure feeding difficulties among residents with dementia in long-term care facilities in Taiwan. Using this reliable and valid tool can help healthcare providers to assess feeding problems of PwD and provide feeding assistance in order to promote quality of care during mealtime in long-term care facilities.

Factors influencing the degree of eating ability among people with dementia

AIMS AND OBJECTIVES

To explore the degree of eating ability in people with dementia and identify what factors affect their eating ability.

BACKGROUND

Appropriate food consumption is important to human life. Although eating difficulties are common among people with dementia, little is known about what factors might influence their eating ability.

DESIGN

Descriptive, cross-sectional study.

METHODS

A total of 149 people with dementia residing in nursing facilities in Seoul or the Gyeonggi area of Korea were evaluated using the Korean Mini-Mental State Examination, Korean Activities of Daily Living Scale and Eating Behaviour Scale. Data were analysed using descriptive statistics, one-way analysis of variance, Pearson correlation coefficient and multiple regression analysis.

RESULTS

The participants showed a moderate level of dependency with respect to eating ability and were most dependent on the use of utensils. There were significant differences in eating ability according to general characteristics such as duration of residence, duration of illness, degree of visual impairment, eating place, and diet type. The eating ability of the participants was significantly correlated with cognitive function and physical function. Cognitive function, physical function, duration of illness, eating place (living room or dining room), and diet type (soft or liquid) significantly predicted eating ability in people with dementia.

CONCLUSIONS

The findings of this study suggest that it is necessary to thoroughly assess the eating ability of people with dementia and to develop appropriate training programs to maintain or improve their remaining eating ability. The creation of a pleasurable physical and social environment for eating might also be helpful.

RELEVANCE TO CLINICAL PRACTICE

These findings would be able to serve a useful basis in the development of materials for nursing intervention programs for people with dementia during mealtimes by improving the techniques and care qualities of nursing caregivers.

Mealtime management in Australian residential aged care: Comparison of documented, reported and observed care

PURPOSE

Mealtime management in Residential aged care facilities (RACFs) should be holistic and comply with the principles of person-centred care (PCC) to ensure residents' medical, nutritional and psychosocial mealtime needs are met. However, this is not always achieved and multiple issues with mealtime management in RACFs exist. The aim of the current study was to compare documented, reported and observed mealtime management to explore factors influencing optimal mealtime care.

METHOD

Data were triangulated from: (a) review of 14 resident files; (b) observation of 41 mealtimes; (c) questionnaires with 14 residents; and (d) questionnaires with 29 staff.

RESULT

Results revealed multiple discrepancies between data sources leading to the delivery of sub-optimal mealtime care. Poor documentation impacted staff knowledge of required mealtime practices resulting in occasions of inconsistent and inappropriate care. Observational and interview data highlighted discrepancies between residents' mealtime preferences and actual practice. In many instances observed care was not holistic nor consistent with PCC.

CONCLUSION

Given the significant medical, nutritional and psychosocial risks associated with poor mealtime management, systematic changes in policy, staff training and multidisciplinary care are needed.

Facilitating ADLs by caregivers of persons with dementia: the C3P model

The purpose of this paper is to explicate a change model for caregivers of persons with dementia to assist them in facilitating meals in the home, at community-based programs and in institutional settings. Building on a Social Ecological Model, the C3P Model-Change the Person, Change the People, Change the Place offers a clear method to adapt care strategies to foster independence while providing appropriate support as the person with dementia cognitively and functionally declines. Meals are highly embedded within a culture and are ritualized events within a family requiring an individualized approach when modifications are needed.

[Malnutrition and dementia in the elderly in German nursing homes. Results of a prevalence survey from the years 2008 and 2009]

BACKGROUND AND OBJECTIVE

Dementia is one of most challenging problems for the care of older people in Germany. Although malnutrition in nursing homes is also associated with dementia, few systematic studies have described health care structures in German nursing homes for people with dementia and their individual nutritional status. Therefore, the aim of this study was to determine dementia-specific differences concerning the nutrition situation for the elderly in German nursing homes.

METHODS

A cross-sectional multicenter study was performed using a standardized multilevel instrument (observation, questionnaire) developed at the University of Maastricht. Variables are indicators for malnutrition and its risks, quality indicators, care dependency and types of interventions.

RESULTS

In the 2008 and 2009 surveys, 53% of 4,777 participants (77.9% women, 22.1% men, mean age 82 years) were identified (based on care documentation) as having dementia. More than one third of this population (n = 759, 85.1% women, 14.1% men, mean age 85 years) was probably malnourished; thus, the prevalence rate in the group of people with dementia was 10% higher compared to the group without dementia. People with dementia showed a higher risk in all relevant risk indicators (weight history, body mass index, and food intake) for malnutrition compared to those without dementia. Furthermore, people with dementia had higher care dependency rates and required more assistance for eating and drinking.

CONCLUSION

The study results confirm the relationship between malnutrition and dementia. The use of standardized nutrition screening tools is not common practice in German nursing homes yet. However, the results suggest that with an increasing risk for malnutrition combined with dementia the proportion of nursing interventions also increases, which means that nurses must react adequately. Nevertheless, the interventions concerning malnutrition should be improved especially with respect to preventive measurements.

Using cognitive-functional assessment to predict self-care performance of memory care tenants

A challenge in admitting individuals with Alzheimer's disease and related dementias into memory care residential facilities is determining the appropriate level of service based on abilities and care needs. At intake, the incoming tenant's functional performance capacity is obtained through family or proxy report corroborated with screening results of global cognitive function. Based on this information, the agency determines the level of service needs; if misjudged, inadequate placement can be stressful for the individual and family and costly for the facility. This study examined the predictive validity of a clinically administered assessment of cognitive-functional performance, Cognitive Performance Test (CPT), in gauging service needs in 4 activities of daily living (ADL; dressing, eating/feeding, showering, and toothbrushing) with 57 tenants residing in a memory care-assisted living facility. Linear regression results revealed a significant relationship between CPT scores and ADL performance in all areas (P < .001) with CPT scores accounting for 51% to 62% of the variability in performance.

Neuroprotective and neurotrophic actions of glucagon-like peptide-1: an emerging opportunity to treat neurodegenerative and cerebrovascular disorders

Like type-2 diabetes mellitus (T2DM), neurodegenerative disorders and stroke are an ever increasing, health, social and economic burden for developed Westernized countries. Age is an important risk factor in all of these; due to the rapidly increasing rise in the elderly population T2DM and neurodegenerative disorders, both represent a looming threat to healthcare systems. Whereas several efficacious drugs are currently available to ameliorate T2DM, effective treatments to counteract pathogenic processes of neurodegenerative disorders are lacking and represent a major scientific and pharmaceutical challenge. Epidemiological data indicate an association between T2DM and most major neurodegenerative disorders, including Alzheimer's and Parkinson's diseases. Likewise, there is an association between T2DM and stroke incidence. Studies have revealed that common pathophysiological features, including oxidative stress, insulin resistance, abnormal protein processing and cognitive decline, occur across these. Based on the presence of shared mechanisms and signalling pathways in these seemingly distinct diseases, one could hypothesize that an effective treatment for one disorder could prove beneficial in the others. Glucagon-like peptide-1 (GLP-1)-based anti-diabetic drugs have drawn particular attention as an effective new strategy to not only regulate blood glucose but also to reduce apoptotic cell death of pancreatic beta cells in T2DM. Evidence supports a neurotrophic and neuroprotective role of GLP-1 receptor (R) stimulation in an increasing array of cellular and animal neurodegeneration models as well as in neurogenesis. Herein, we review the physiological role of GLP-1 in the nervous system, focused towards the potential benefit of GLP-1R stimulation as an immediately translatable treatment strategy for acute and chronic neurological disorders.

Nutrition in severe dementia

An increasing proportion of older adults with Alzheimer's disease or other dementias are now surviving to more advanced stages of the illness. Advanced dementia is associated with feeding problems, including difficulty in swallowing and respiratory diseases. Patients become incompetent to make decisions. As a result, complex situations may arise in which physicians and families decide whether artificial nutrition and hydration (ANH) is likely to be beneficial for the patient. The objective of this paper is to present methods for evaluating the nutritional status of patients with severe dementia as well as measures for the treatment of nutritional disorders, the use of vitamin and mineral supplementation, and indications for ANH and pharmacological therapy.

Artificial nutrition and hydration at the end of life

Considerable controversy surrounds the issue of care at the end of life (EOL) for older adults. Technological advances and the legal, ethical, clinical, religious, cultural, personal, and fiscal considerations in the provision of artificial hydration and nutrition support to older adults near death are presented in this comprehensive review.

Time travel: the lived experience of providing feeding assistance to a family member with dementia

A major concern facing family members of people with advanced dementia is deciding how to provide food and water. Nurses play a significant role in supporting mealtimes, yet little is known about the meaning of mealtime for family caregivers of people with dementia. The purpose of this phenomenological study was to explore the experience of providing feeding assistance to a family member with dementia from the perspective of community and nursing home family caregivers. Data were collected through in-depth interviews with 16 family caregivers of individuals with advanced dementia. Analysis revealed that the experience was likened to living in a time warp whereby family caregivers were propelled from pleasant memories of the past, to the stark reality of the present, to a foreboding and uncertain future. Findings can guide nurses to dialogue with family members and to ensure that the full spectrum of mealtime is preserved.

Dysphagia and aspiration pneumonia in older adults

PURPOSE

To review the risks, diagnosis, management, and prevention of aspiration pneumonia in adults over age 65, and discuss the major role of dysphagia as a risk factor in this population.

DATA SOURCES

A comprehensive search of the literature using PubMed (MedLine) and CINAHL.

CONCLUSIONS

Aspiration pneumonia is a common diagnosis in older adults and is associated with significant morbidity and mortality. Oropharyngeal and esophageal dysphagia, often related to stroke, dementia, poor oral hygiene, or multiple chronic illnesses, increases the risk of aspiration. Nurse practitioners (NPs) need to be aware that frequent episodes of pneumonia may be caused by aspiration: therefore it is prudent to identify dysphagia and implement precautions.

IMPLICATIONS FOR PRACTICE

Numerous physical, cognitive, or environmental factors have been identified as predictors of aspiration pneumonia. Knowledge of clinical features, treatments, and prevention will help NPs improve outcomes in older adults with aspiration pneumonia; especially those in long-term care.

Serum trace elements in elderly frail patients with oropharyngeal dysphagia

Microelements have an important role in many vital enzymatic functions. Their optimal intake and serum concentration are not properly defined. For nursing home residents, this issue is further complicated by the high prevalence of oropharyngeal dysphagia. The purpose of this study was to measure microelement concentrations in 3 groups of elderly subjects that differ in their feeding methods and functional state. Forty-six frail elderly patients, in stable clinical condition, 15 on naso-gastric tube (NGT) feeding, 15 orally fed (OF), from skilled nursing departments were recruited to this study. As controls, we studied a group of 16 elderly independent ambulatory patients. A battery of 16 microelements was examined using the Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The OF frail elderly patients had significantly lower levels of chromium as compared to the NGT fed and the control group. Both frail elderly groups had lower levels of zinc and copper as compared to the controls. In contrast, in the nursing groups, we found higher levels of aluminum, boron, barium, bromine and nickel. Elderly, in particular frail and disabled subjects, are vulnerable to insufficiency or overload of microelements. There is a need to evaluate the actual requirements for each microelement for this population.

Nurses' perspectives on feeding decisions for nursing home residents with advanced dementia

AIM

To develop a broad understanding of nursing beliefs, knowledge and roles in feeding decisions for nursing home residents with advanced dementia.

BACKGROUND

Concern is growing about the common use of feeding tubes in nursing home residents with advanced dementia. Nurses can play an important role in providing information and guiding family members through difficult feeding decisions. Little is known about nurses' perspectives on feeding decisions.

DESIGN

Qualitative descriptive.

METHODS

In-depth semi-structured interviews of 11 licensed nurses who were experienced in caring for nursing home residents with dementia.

RESULTS

Analysis of the interview transcripts revealed three themes: insufficient empirical information, ambiguous role in feeding decisions and uncertainty about moral agency in decisions about the placement of feeding tubes.

CONCLUSIONS

Despite views that family members would benefit from guidance in decisions regarding the placement of feeding tubes, nurses were, nevertheless, reluctant to become involved in these difficult decisions.

RELEVANCE TO CLINICAL PRACTICE

If nurses are to guide family members in decisions about the use of feeding tubes, they need more education about evidence-based practice as well as support in exercising their nursing responsibilities.

Nutritional issues in long-term care

Because long-term care residents often have chronic illnesses and complex care regimens, nutritional issues are common in these populations. Furthermore, management is complicated because some residents are terminally ill and under palliative care treatment plans that allow for dehydration and low oral intake. As a result, the medical management of nutrition is complex and challenging for medical providers caring for residents of nursing homes, assisted living facilities, and other long-term care settings. Quality nutritional practice in long-term care involves careful assessment of barriers to adequate nutrition; reduction of risk factors; attention to specialized diets, food presentation, and supplements, when appropriate; awareness of the importance of psychosocial and environmental issues; and consideration of the role of medication both as a cause and a therapeutic adjunct. Optimal practice at a facility level would involve a systematic approach to applying the best evidence-based approaches, with a focus on individualizing each resident's nutritional management.

Feeding difficulty in older adults with dementia

AIMS AND OBJECTIVES

To use concept analysis to identify characteristics of feeding difficulty and its antecedents and consequences that provide direction for assessment and management.

BACKGROUND

Feeding difficulty is often recognised as a common problem for older adults and is associated with weight loss, poor nutrition and risk for aspiration pneumonia. The cognitive impairment found in persons with dementia impairs the ability of these adults to complete motor and perceptual tasks required for eating and often prevent the older adult from accepting help with feeding from caregivers.

DESIGN

Systematic review.

METHODS

In 2006, literature searches using keywords (feeding, eating, nutrition, malnutrition, feeding assessment, dementia, ageing and concept analysis, dementia and feeding and excluding enteral feeding, tube feedings, PEG and enteral nutrition) were done in Medline, CINHAL, AGELINE and Social Science Full Text. Seventy relevant articles in English were found. After a review of the relevant articles, concept analysis was used to develop a definition of feeding difficulty, its defining characteristics and to delineate feeding difficulty from its antecedents and consequences.

RESULTS

Feeding difficulties arise at the interface between the caregiver strategies to assist the older adult with getting food into the mouth and chewing and swallowing food. A model of feeding difficulty delineates the antecedents and consequences of feeding difficulties.

CONCLUSIONS

The conceptual model of feeding difficulties provides a strong and clear organising structure for research that can be used to developed evidence based guidelines for practice.

RELEVANCE TO CLINICAL PRACTICE

The conceptual model provides directions for assessment of feeding difficulties and their antecedents. The model can be used to identify interventions that address antecedents of feeding difficulty (risk factors) and different types of feeding difficulties.

Feeding alternatives in patients with dementia: examining the evidence

Percutaneous endoscopic gastrostomy tubes are being placed with increasing frequency in the United States among elderly patients with dementia. Health care providers believe there may be long-term benefits for enteral feeding in this population, yet previous study of this topic has failed to yield any convincing evidence to support this hypothesis. In this study, we review the evidence regarding outcomes for artificial enteral feeding in older individuals with dementia. We found that there is a lack of evidence supporting artificial feeding in the specific outcomes of survival, pressure ulcers, nutrition, and aspiration pneumonia. A brief discussion regarding hand feeding is included. The data suggest that hand feeding may be a viable alternative to tube feeding in elderly patients with dementia, although a direct comparison trial of the 2 interventions is lacking.

A Preliminary Evaluation of the Paid Feeding Assistant Regulation: Impact on Feeding Assistance Care Process Quality in Nursing Homes

PURPOSE

The Centers for Medicare and Medicaid Services and the Agency for Healthcare Research and Quality sponsored a nationwide study to evaluate the federal paid feeding assistant (PFA) regulation that allows nursing homes to hire single-task workers to provide feeding assistance to nursing home residents. Organizers designed the PFA regulation to increase the number of staff available to provide assistance with eating and improve nutritional care process quality.

DESIGN AND METHODS

Trained research staff used standardized protocols to conduct direct observations during meals and face-to-face staff interviews in a convenience sample of seven facilities with PFA programs to evaluate care process quality.

RESULTS

Most (84%) of the trained PFAs in the seven site visit facilities were non-nursing staff within the facility; the quality of feeding assistance care provided by these workers was comparable to that provided by indigenous nurse aides. There were no reported changes in existing staffing levels (nurse aide or licensed nurses) following PFA program implementation, and the majority (> 90%) of indigenous staff at all levels reported positive benefits of the PFA program for both staff and residents.

IMPLICATIONS

Findings from this preliminary study indicate that the PFA regulation may serve to increase the utilization of existing non-nursing staff to improve feeding assistance care during meals without having a negative impact on existing nurse aide and licensed nurse staffing levels.

Thickened Fluids and Water Absorption in Rats and Humans

Individuals with dysphagia are commonly provided with oral fluids thickened to prevent aspiration. Most thickening agents are either gum-based (guar or xanthan) or are derived from modified starches. There is evidence, predominantly anecdotal, that dysphagic individuals are subclinically dehydrated. Dysphagia has a particular impact on elderly individuals and there is justifiable concern for dehydration in this population. It has been speculated that dehydration may, in part, be the result of the water-holding capacity of these thickening agents decreasing water absorption from the gut. The aim of this study was to determine the rate of intestinal absorption of water from thickened fluids. The method used was a laboratory tracer study in rats and humans in vivo. We found that there were no significant differences in water absorption rates between thickened fluids or pure water irrespective of thickener type (modified maize starch, guar gum, or xanthan gum). These data provide no support for the view that the addition of thickening agents, irrespective of type, to orally ingested fluids significantly alters the absorption rate of water from the gut.

Reframing person-centered nursing care for persons with dementia

Alzheimer's dementia manifests in a complex clinical presentation that has been addressed from both biomedical and phenomenological perspectives. Although each of these paradigmatic perspectives has contributed to advancement of the science, neither is adequate for theoretically framing a person-centered approach to nursing care. The need-driven dementia-compromised behavior (NDB) model is discussed as an exemplar of midrange nursing theory that promotes the integration of these paradigmatic views to promote a new level of excellence in person-centered dementia care. Clinical application of the NDB promotes a new level of praxis, or thoughtful action, in the care of persons with dementia.

Careful Hand Feeding: A Reasonable Alternative to PEG Tube Placement in Individuals with Dementia

Individuals with dementia inevitably experience decreased oral intake when they are no longer able to recognize food, feed themselves independently, or experience swallowing difficulties. There is mounting evidence that routine insertion of a percutaneous endoscopic gastrostomy (PEG) does not significantly affect survival, nor does it reduce the risk of aspiration pneumonia and pressure ulcer formation. Although there is relatively little published on assisted oral feeding, its advantages include allowing the patient to enjoy the gratification of eating and socialization that accompanies mealtime, as well as avoiding restraint use that often accompanies PEG placement. Nurses can play a pivotal role in assessment of feeding difficulties, implementation of innovative mealtime programs, educating families about specific strategies to optimize oral intake, and participating in research to evaluate patient outcomes.

PEGs and Ethics Revisited

Percutaneous endoscopic gastrostomy is an accepted technique for long-term enteral feeding. The demand of percutaneous endoscopic gastrostomy placement continues to increase because of the increasing numbers of vulnerable patients with chronic diseases coupled with the relative ease of insertion, and societal ambivalence about such treatment. Despite the demand and improvements in placement technique, the issue of tube feeding in vulnerable patients remains an ethical minefield, leading to considerable discussion and debate. This contentious area of clinical ethics is further complicated by the recent papal allocution regarding artificial nutrition and hydration. The case of Terri Schiavo should serve as a timely reminder of those problematic clinical and ethical issues inherent in percutaneous endoscopic gastrostomy placement and feeding in vulnerable patients.
