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

Understanding mealtime behavioral problems in nursing home residents living with dementia: a group concept mapping approach

BACKGROUND

Persons with dementia frequently experience mealtime behavioral problems that can result in reduced or lack of intake of food or fluids. Multiple underlying causes and expressions of mealtime behavioral problems complicate its interpretation and intervention, because problems originating from cognitive and functional decline and behavioral changes may interact. Healthcare professionals and family caregivers may encounter a variety of practical and moral dilemmas in dealing with these problems. We aimed at a better understanding of mealtime behavioral problems and related complex issues in nursing home residents with dementia from a daily practice perspective.

METHODS

We used a mixed-method Group Concept Mapping approach in this study, and collected data online with a panel of 67 healthcare professionals, researchers and relatives from across The Netherlands. The participants contributed to either or all of the following phases: (1) the generation of ideas (brainstorm), (2) sorting, and (3) rating of the ideas. Subsequent phases included data analysis with Groupwisdom® software and interpretation of the results. Multidimensional scaling and hierarchical cluster analysis resulted in a concept map visualizing the coherence and importance of ideas. Bridging values were calculated, with low values indicating a distinct, clear concept.

RESULTS

Brainstorming resulted in 285 statements representing 85 ideas. The concept map visualized three categories capturing ten clusters which describe the management of mealtime behavioral problems, causes of mealtime behavioral problems, and expressions and interpretations of mealtime behavioral problems. Concepts reflecting direct consequences, ethical components, and considerations to handle challenging situations overlapped on the concept map with the highest bridging values (range 0.58-0.87).

CONCLUSION

This study added to unraveling the complex nature of mealtime behavioral problems, as perceived in practice. It is recommended to comprehensively analyze all components in the management of these problems, in particular being aware of ethical factors and align care for residents with dementia accordingly.

Actual situation of nutritional management and factors related to activities of daily living ability at discharge in convalescent rehabilitation ward

Saito T, Kamachi M. Actual situation of nutritional management and factors related to activities of daily living ability at discharge in convalescent rehabilitation ward. Jpn J Compr Rehabil Sci 2024; 15: 71-78.

Objective

In this study, we aimed to investigate changes in the Geriatric Nutritional Risk Index (GNRI), a nutrition-related prognostic indicator, in our convalescent rehabilitation ward and determine how this index relates to activities of daily living (ADL) ability at discharge.

Methods

We retrospectively analyzed data of 107 patients admitted to our convalescent rehabilitation ward between April and September 2023. We used the GNRI as the nutritional risk index and Functional Independence Measure (FIM) as the ADL index.

Results

The patients' mean age was 80.0 ± 10.3 years; 38 were males and 69 females. The patients' mean body weight at admission was 51.2 ± 10.2 kg, which significantly decreased to 50.2 ± 9.4 kg at discharge (p = 0.0006). Their mean body mass index (BMI) also significantly decreased from 21.4 ± 3.4 at admission to 20.0 ± 8.2 at discharge (p = 0.002). The mean GNRI significantly decreased from 93.1 ± 8.6 at admission to 91.7 ± 8.4 at discharge (p = 0.023). The mean body weight decreased until the fourth month after admission; however, no decreasing trend after the fifth month was observed. The mean monthly energy intake gradually increased after admission and reached the calculated energy requirement of 1,415 ± 22 kcal at the fifth month. Multivariate analysis demonstrated that at discharge, the GNRI score was positively associated with the FIM score (β = 0.21, p = 0.0008).

Conclusion

Body weight and GNRI scores decreased after admission but stopped decreasing after the fifth month due to a gradual increase in energy intake. At discharge, the FIM score was positively associated with the GNRI score. We expected that active nutritional therapy from the beginning of hospitalization would increase the GNRI by the time of discharge and eventually improve ADL ability at discharge.

Assessing eating ability and mealtime behaviors of persons living with dementia: A systematic review of instruments

This systematic review aimed to describe the characteristics of instruments that assess eating ability and/or mealtime behaviors in persons living with dementia, and evaluate their psychometric properties. Five databases were searched for relevant records between 1/1/1980 and 5/25/2023. Records included instruments assessing eating ability and/or mealtime behaviors of people with dementia. The psychometric quality of the instruments was evaluated using the Psychometric Assessment for Self-report and Observational Tools (PAT). 45 eligible instruments were identified from 115 records. While 38 instruments were scored as having low psychometric quality, 7 had moderate quality. Edinburgh Feeding Evaluation in Dementia (EdFED), Mealtime Difficulty Scale for older adults with Dementia (MDSD), and Dementia Hyperphagic Behavior Scale (DHBS) were scored as having the highest quality (total PAT score = 9). Further refinement of existing instruments and additional psychometric testing in larger, diverse samples will improve pragmatic use in dementia mealtime care research and practice.

Nutritional Care for Institutionalized Persons with Dementia: An Integrative Review

BACKGROUND

Older people are at risk of malnutrition, especially when they suffer from cognitive impairment. Guidelines that orient nursing care in this regard need to be updated. The aim of this review is to address the best available evidence on interventions that can benefit nutritional nursing care for institutionalized older adults with dementia.

METHODS

Integrative review using the Dimensions and Eureka search engines, and the PubMed, Embase, Scielo, CINAHL, and ScienceDirect databases. We searched from the year 2015 through to 2021. We employed the MMAT guidelines for mixed, qualitative, and quantitative studies, and the PRISMA, CASP, and JBI guidelines to value the reviews.

RESULTS

A total of 55 studies met the inclusion criteria. The best available evidence to support nutritional nursing care for institutionalized older adults with dementia highlights several aspects related to the assessment and caring interventions that are focused on people with dementia, their caregivers, and their context.

CONCLUSIONS

Both the assessment and nutritional care interventions for older people with dementia should consider the patient-caregiver dyad as the subject of care and understand the context as a fundamental part of it. The analysis of the context should look further than the immediate environment.

Prevalence of Malnutrition in People with Dementia in Long-Term Care: A Systematic Review and Meta-Analysis

Dementia is a common syndrome in older people. Dementia alters eating behaviors, hunger and thirst cues, swallow function, ability to self-feed, and recognition and interest in food. There is significant variation in the reported prevalence of malnutrition among older people who live in long-term care. The aim was to conduct a systematic literature review and meta-analysis of the prevalence of malnutrition in those with dementia living in long-term care using a validated nutrition assessment tool. Scopus, Web of Science, CINAHL, and Medline were searched. A random effects model was used to determine the prevalence and risk of malnutrition. Data were retrieved from 24 studies. Most of the studies were from Europe or South Asia. The prevalence of malnutrition ranged from 6.8 to 75.6%, and the risk of malnutrition was 36.5-90.4%. The pooled prevalence of malnutrition in those with dementia in long-term care was 26.98% (95% CI 22.0-32.26, p < 0.0001, I² = 94.12%). The pooled prevalence of the risk of malnutrition in those with dementia was 57.43% (95% CI 49.39-65.28, p < 0.0001, I² = 97.38%). Malnutrition is widespread in those with dementia living in long-term care. Further research exploring malnutrition in other industrialized countries using validated assessment tools is required.

Longitudinal assessment of the eating pattern of people with dementia and its association with problems for feeding and malnutrition: a prospective follow-up study protocol

INTRODUCTION

Dementia conditions the patient's nutrition from the beginning and vice versa. Generating difficulties for feeding (FEDIF) will influence its evolution. There are currently few nutritional longitudinal studies in people with dementia. Most focus on problems already established. The Edinburgh Feeding Evaluation in Dementia (EdFED) Scale identifies FEDIF of patients with dementia by studying their behaviours while eating or being fed. It also indicates areas of potential clinical interventions.

METHODS AND ANALYSIS

Prospective multicentre observational study carried out in nursing homes, Alzheimer's day care centres and primary healthcare centres. The study population will be dyads composed by the patient (diagnosed of dementia, over 65 years of age and who have feeding difficulties) and their family caregiver. Sociodemographic variables and nutritional status (body mass index, Mini Nutritional Assessment, blood test and calf and arm circumference) will be assessed. The Spanish version of the EdFED Scale will be completed and the presence of nursing diagnoses related to feeding behaviours will be collected. Follow-up will take place for 18 months.

ETHICS AND DISSEMINATION

All data will be carried out respecting European legislation 2016/679 in data protection, and the Spanish 'Organic Law 3/2018 of December 2005'. The clinical data will be kept segregated and encrypted. The informed consent has been obtained. The research has been authorised by the Costa del Sol Health Care District on 27 February 2020 and the Ethics Committee on 2 March 2021. It has obtained funding from the Junta de Andalucía on 15 February 2021. Findings of the study will be presented at provincial, national and international conferences and published in peer-reviewed journals.

Measuring mealtime performance in older adults with suspected oropharyngeal dysphagia: an updated systematic review of psychometric properties

PURPOSE

To update a previous review of psychometric properties of performance-based outcome measurement instruments (PerFOMs) for task performance in the context of meal activity of older adults (≥65 years) with suspected oropharyngeal dysphagia (OD).

MATERIALS AND METHODS

Systematic searches were conducted in PubMed, CINAHL, EMBASE, SCOPUS, and Web of Science. Studies on PerFOMs that covers items reflecting skills in the pre-oral, oral, and pharyngeal stages of ingestion during meals were included. Two review authors independently screened, extracted, and evaluated the methodological rigour and quality of the reported psychometric properties in the included studies using the guidelines of the COnsensus-based Standards for the Selection of health Measurement INstruments (COSMIN).

RESULTS

Twenty-three articles featuring nine original PerFOMs and five translated versions were included. PerFOM development and content validity were rated with inadequate or doubtful methodological quality across all studies. The quality of the evidence across the additional psychometric properties of the PerFOMs was very low for two, ranged from very low to moderate for six, and from very low to high for five.

CONCLUSIONS

There is limited evidence of the psychometric properties of available PerFOMs for measuring task performance during meals in older adults with OD, and further validation is warranted.Implication for rehabilitationAssessing the mealtime performance of older adults with oropharyngeal dysphagia (OD) provides important information.Performance-based outcome measurement instruments (PerFOMs) need to be valid and reliable.Clinicians need to be careful when choosing PerFOMs to assess the mealtime performance of older adults with OD as there is insufficient evidence on the quality of available instruments.Established guidelines and standards should be used when developing and investigating psychometric properties of PerFOMs assessing mealtime performance of older adults with OD.

Eating Difficulties and Relationship With Nutritional Status Among Patients With Dementia

BACKGROUND

One of the most common behavioral problems in patients with dementia is eating problems, which are known to increase the risk of malnutrition. However, few studies have been conducted in this patient group regarding the relationship between eating difficulties and nutritional status.

PURPOSE

This study was designed to determine the eating difficulties faced by patients with dementia and to evaluate the relationship in this population between eating difficulties and malnutrition.

METHODS

This study was carried out in a dementia outpatient clinic of a university hospital in Istanbul, Turkey. This cross-sectional, case-control study included 50 patients and 50 healthy controls as participants. Participants were assessed for eating difficulties and for nutritional, cognitive, and functional statuses.

RESULTS

The patients with dementia had more difficulties in terms of self-feeding skills. Although problems related to manipulating food on the plate and the use of utensils were not seen in the control group, these problems were found in 30% of the participants in the dementia group ( p < .001). Moreover, 30% of the patients in the dementia group were unable to eat without assistance ( p < .001). Associations were found between eating difficulties and age, duration of illness, and cognitive and functional (basic and instrumental activities of daily living) statuses. In addition, self-feeding skills were found to be associated with nutritional status. Rate of malnutrition or risk of malnutrition was higher in patients with dementia than in those in the control group.

CONCLUSIONS

In this study, compared with the control group, patients with dementia had more problems in self-feeding skills such as manipulation of food on a plate, use of utensils, need for assistive tools, ability to eat without assistance, and negative eating behaviors (refusal to eat). An association was found between eating difficulties and nutritional status. Evaluating eating difficulties is recommended in patients with dementia to prevent nutritional deterioration.

Sex, Age, and Regional Differences in CHRM1 and CHRM3 Genes Expression Levels in the Human Brain Biopsies: Potential Targets for Alzheimer's Disease-related Sleep Disturbances

BACKGROUND

Cholinergic hypofunction and sleep disturbance are hallmarks of Alzheimer's disease (AD), a progressive disorder leading to neuronal deterioration. Muscarinic acetylcholine receptors (M1-5 or mAChRs), expressed in hippocampus and cerebral cortex, play a pivotal role in the aberrant alterations of cognitive processing, memory, and learning, observed in AD. Recent evidence shows that two mAChRs, M1 and M3, encoded by CHRM1 and CHRM3 genes, respectively, are involved in sleep functions and, peculiarly, in rapid eye movement (REM) sleep.

METHODS

We used twenty microarray datasets extrapolated from post-mortem brain tissue of nondemented healthy controls (NDHC) and AD patients to examine the expression profile of CHRM1 and CHRM3 genes. Samples were from eight brain regions and stratified according to age and sex.

RESULTS

CHRM1 and CHRM3 expression levels were significantly reduced in AD compared with ageand sex-matched NDHC brains. A negative correlation with age emerged for both CHRM1 and CHRM3 in NDHC but not in AD brains. Notably, a marked positive correlation was also revealed between the neurogranin (NRGN) and both CHRM1 and CHRM3 genes. These associations were modulated by sex. Accordingly, in the temporal and occipital regions of NDHC subjects, males expressed higher levels of CHRM1 and CHRM3, respectively, than females. In AD patients, males expressed higher levels of CHRM1 and CHRM3 in the temporal and frontal regions, respectively, than females.

CONCLUSION

Thus, substantial differences, all strictly linked to the brain region analyzed, age, and sex, exist in CHRM1 and CHRM3 brain levels both in NDHC subjects and in AD patients.

Non-Pharmacological Interventions for Feeding and Eating Disorders in Persons with Dementia: Systematic Review and Evidence Summary

BACKGROUND

Feeding and eating disorders related to cognitive and psycho-behavioral symptoms are strongly associated with health status in persons with dementia (PWD). Non-pharmacological interventions have been the priority selection to address this significant issue. However, the direct targets of non-pharmacological interventions are unclear and there is no consistent evidence of recommendations on the intervention of different dementia stages and the settings of intervention practice.

OBJECTIVE

To provide caregivers with a set of self-help non-pharmacological interventions for feeding and eating disorders in PWD.

METHODS

Based on the process of evidence summary, a systematic literature search was performed on dementia websites and seven databases. Two researchers screened the studies independently and appraise the quality. The evidence was graded by Joanna Briggs Institute Grades of Recommendation.

RESULTS

Twenty-eight articles were included. Twenty-three non-pharmacological intervention recommendations were categorized into six themes containing oral nutritional supplementation, assistance with eating and drinking, person-centered mealtime care, environmental modification, education or training, and multi-component intervention. These interventions corresponded to three direct targets including improving engagement, making up for loss ability, and increasing food intake directly. They were applied to different stages of dementia and most interventions were targeted at PWD in long-term care institutions.

CONCLUSION

This article summarized the direct targets and the specific implementation of recommendations at different stages of dementia to provide caregivers with self-help non-pharmacological interventions. The practice of recommendations was more applicable to institutionalized PWD. When applied to PWD at home, caregivers need to identify the specific feeding and eating conditions at different stages and adopted the interventions in conjunction with the wishes of the PWD and professional advice.

Resistance to Eating in People with Dementia Living in Long-term Care Facilities: Gaps between Common and Good Practices

OBJECTIVES

The present study aims to explore the perception of common and best practices for dealing with resistance to eating of persons with dementia living in long-term care facilities.

METHODS

Forty-two staff members working in long-term care facilities were interviewed. They worked in four Spanish long-term care facilities; 21 were nursing assistants and 21 technical staff. Participants heard a vignette in which person with dementia showed resistance to eating. Participants were asked how a situation like that is commonly managed by their workmates, and how the situation should be managed. Responses were content-analyzed.

RESULTS

Strategies mentioned by participants were quite diverse and did not converge on common ground that harmonizes their responses. Less than half of the participants considered person-centered strategies as a best practice. Those strategies were lower on assistant carers, compared to technical staff.

CONCLUSIONS

Resistance to eating is a common situation faced by professionals. Nonetheless, there is not a common procedure to deal with this situation. Resistance to eating was seen more as a problem to be eradicated than a behavior to be understood.

CLINICAL IMPLICATIONS

Staff development initiatives are necessary in relation to mealtime situations. They should consider work position and competencies needed by assistant carers.

Effect of nutritional status before femoral neck fracture surgery on postoperative outcomes: a retrospective study

Background

Although nutritional status is crucial in gait recovery after femoral neck fracture surgery, the relationship between preoperative nutritional status and postoperative outcomes remains unknown. This study examined the effects of preoperative nutritional status on postoperative outcomes in patients undergoing femoral neck fracture surgery.

Methods

Data regarding the joints of 137 patients (29 men, 108 women) who underwent bipolar hemiarthroplasty for femoral neck fractures at our hospital from January 2015 to December 2019 were retrospectively examined. The Geriatric Nutritional Risk Index (GNRI), an index of nutritional status, was used to classify patients into two groups: a normal group (GNRI ≥92; n = 62) and an undernourished group (GNRI < 92; n = 75). The study endpoints included age at surgery, sex, Mini Mental State Examination (MMSE), American Society of Anesthesiologists Physical Status (ASA) classification, preoperative waiting period, intraoperative blood loss, surgery time, perioperative hemoglobin levels, blood transfusion rate, complication rate, 6-month mortality rate, transfer rate, percentage of patients unable to walk at discharge or transfer, and inability to walk 6 months postoperatively.

Results

The patients in the undernourished group was significantly older at surgery (p < 0.01) and had a lower perioperative hemoglobin levels (p < 0.01), a higher blood transfusion rate (p < 0.01), a lower MMSE (p < 0.01), a longer preoperative waiting period (p < 0.05), a higher transfer rate (p < 0.05), were more likely to be unable to walk 6 months postoperatively (p < 0.01), a higher complication rate (p < 0.05), and a higher 6-month mortality rate (p < 0.01) than the normal group. Patients in the undernourished group had worse rates of postoperative complications, transfer, mortality, and inability to walk 6-month after surgery than those in the normal group.

Conclusions

A poor nutritional status affects the gait function and systemic condition of patients undergoing femoral neck fracture surgery; therefore, early nutritional interventions may reduce mortality rates and shorten rehabilitation. These results suggest that the GNRI effectively predicts postoperative complications, mortality, and gait function.

Eating Difficulties among Older Adults with Dementia in Long-Term Care Facilities: A Scoping Review

This paper reports a scoping review of the literature on eating difficulties among older adults with dementia in long-term care facilities to identify key concepts, methods of measuring outcomes, interventions, and related factors. A scoping review was performed using the bibliographic databases PubMed, CINAHL, PsycINFO, and Cochrane Library. A combination of keywords and subject headings related to eating or feeding difficulties was used. Inclusion criteria were limited to materials published in English. A total of 1070 references were retrieved, of which 39 articles were selected after applying the inclusion and exclusion criteria. Articles that met the criteria were published between 1987 and 2020. “Eating disabilities” have been defined as problems related to choosing food and/or the ability to get food to one’s mouth, chew, and swallow. Interventions for eating difficulties described in the literature include spaced retrieval training, Montessori training, and feeding skill training. Intrapersonal, interpersonal, and environmental factors related to eating difficulties were identified. This scoping review will provide direct care workers, nursing educators, and administrators with an overview of eating performance and a broad understanding of eating difficulties for older adults with dementia in long-term care facilities.

Dementia Enlightened?! A Systematic Literature Review of the Influence of Indoor Environmental Light on the Health of Older Persons with Dementia in Long-Term Care Facilities

Light therapy for older persons with dementia is often administered with light boxes, even though indoor ambient light may more comfortably support the diverse lighting needs of this population. Our objective is to investigate the influence of indoor daylight and lighting on the health of older adults with dementia living in long-term care facilities. A systematic literature search was performed within PubMed, CINAHL, PsycINFO, Web of Science and Scopus databases. The included articles (n=37) were published from 1991 to 2020. These articles researched the influence of existing and changed indoor light conditions on health and resulted in seven categories of health outcomes. Although no conclusive evidence was found to support the ability of indoor light to decrease challenging behaviors or improve circadian rhythms, findings of two studies indicate that exposure to (very) cool light of moderate intensity diminished agitation. Promising effects of indoor light were to reduce depressive symptoms and facilitate spatial orientation. Furthermore, there were indications that indoor light improved one’s quality of life. Despite interventions with dynamic lighting having yielded little evidence of its efficacy, its potential has been insufficiently researched among this study population. This review provides a clear and comprehensive description of the impact of diverse indoor light conditions on the health of older adults with dementia living in long-term care facilities. Variation was seen in terms of research methods, (the description of) light conditions, and participants’ characteristics (types and severity of dementia), thus confounding the reliability of the findings. The authors recommend further research to corroborate the beneficial effects of indoor light on depression and to clarify its role in supporting everyday activities of this population. An implication for practice in long-term care facilities is raising the awareness of the increased lighting needs of aged residents.

Mealtime verbal interactions among nursing home staff and residents with dementia: A secondary behavioural analysis of videotaped observations

AIMS

To characterize dyadic mealtime verbal interactions and examine the associations with staff and resident characteristics.

DESIGN

A secondary analysis of 110 videotaped mealtime observations collected from a dementia communication trial during 2011-2014.

METHODS

Videos involved 25 residents with dementia and 29 staff in nine nursing homes. Verbal behaviours (utterances) were coded during 2018-2019 using the Cue Utilization and Engagement in Dementia mealtime video-coding scheme, addressing eight positive behaviours and four negative behaviours. Bivariate analyses and multivariate regression models were used.

RESULTS

Staff spoke three times more frequently (76.5%) than residents (23.5%). Nearly all staff utterances were positive (99.2%); 85.1% of residents' utterances were positive and 14.9% negative. Staff positive utterances were correlated with their negative utterances and resident positive and negative utterances. Staff negative utterances were correlated with resident negative utterances. Resident positive and negative utterances were correlated. Resident positive utterances were significantly associated with staff care-giving length in the current nursing home (OR = 1.430, 95% CI = 1.008, 2.027). Resident negative utterances were significantly associated with resident gender (female versus male, OR = 11.892, 95% CI = 1.237, 114.289) and staff years worked as a caregiver (OR = 0.838, 95% CI = 0.710, 0.989). Staff positive and negative utterances were not associated significantly with any participant characteristics.

CONCLUSIONS

Staff engage residents using primarily positive verbal strategies. Staff-resident mealtime verbal interactions were dynamic, interactive, and complex and related to multiple individual characteristics.

IMPACT

Positive dyadic mealtime interactions are critical to engage residents in eating. Little work has characterized dyadic mealtime interactions, limiting the development of effective interventions. Findings showed staff-resident mealtime verbal interactions were primarily positive, inter-related, and associated with multiple individual characteristics. Findings inform directions to improve mealtime care practice and develop person-centred mealtime interventions targeting modifiable factors, including staff care-giving experiences.

Are patients with cognitive impairment fit to fly? Current evidence and practical recommendations

BACKGROUND

The worldwide prevalence of dementia is increasing and represents a major public health concern. In the last decades, air travel services have undergone an impressive expansion and one of ten passengers is aged 65 years and older. While air travel can be stressful at all ages and health conditions, older individuals with cognitive impairment carry a greater risk for air-travel-related complications. Consequently, demands to general practitioners for assessing their older patient's fitness to fly are increasing.

METHODS

We conducted a search of the literature in PubMed on the impact of in-flight environmental changes on passengers with cognitive impairment and possible resulting complications. This set the base for a discussion on pharmacological and non-pharmacological interventions aimed at preventing in-flight complications in this vulnerable population.

RESULTS

While our research strategy identified a total of 11 articles related to older age and air travel, only three focused on passengers with cognitive impairment. Our literature review showed that the airplane environment may lead to a large spectrum of symptoms in passengers of all age groups. However, passengers with cognitive impairment due to neurodegenerative diseases are at increased risk for experiencing the most extreme symptoms such as acute confusional state. Non-pharmacological and pharmacological interventions at different stages of the travel process (before, during and after) can help prevent complications in this vulnerable population.

CONCLUSION

The decision to let a patient with cognitive impairment fly requires a solid understanding of the in-flight environmental changes and their impact on older patients with cognitive impairment. Moreover, a sound weighing of the risks and benefits while considering different aspects of the patient's history is demanded. In this regard, the role of the treating physicians and caregivers is essential along with the support of the medical department of the airline.

Food intake is associated with verbal interactions between nursing home staff and residents with dementia: A secondary analysis of videotaped observations

BACKGROUND

Nursing home residents with dementia commonly experience low food intake, leading to negative functional and nutritional consequences. While the importance of staff-resident (dyadic) interactions during mealtime is acknowledged, little research has examined the role of dyadic verbal interactions on food intake.

OBJECTIVES

This study aimed to examine the relationship between food intake and dyadic verbal interactions.

METHODS

This study was a secondary analysis of 110 videotaped observations of mealtime care interactions among 25 residents with dementia and 29 staff (42 unique dyads) in 9 nursing homes. Staff positive utterances and resident positive and negative utterances (independent variables) and food intake (dependent variable) were coded from the videotaped observations using the Cue Utilization and Engagement in Dementia video coding scheme. A linear mixed model was fit to the data. The two-way interaction effects of food type and video duration with each independent variable as well as two-way interaction effects among the independent variables were tested. Covariates included in the model were the number of years staff worked as a caregiver, and resident age, gender, and eating function.

RESULTS

The model included three significant interaction effects involving verbal variables: the interaction effect of staff positive utterances with resident positive utterances (p=.030), the interaction effect of staff positive utterances with food type (p=.027), and the interaction effect of resident negative utterances with video duration (p=0.002). Increased number of intakes of liquid food per minute was associated with increased number of staff positive utterances per minute when residents did not make positive utterances. Decreased number of intakes of solid food per minute was associated with increased number of staff positive utterances per minute, especially when residents made between 0 and 3 positive utterances per minute. As the duration of the videos increased, the number of intakes per minute increased for residents who made one or more negative utterances and decreased for residents who made no negative utterances in the videos. The number of intakes per minute was associated with resident gender in that male residents had increased number of intakes per minute compared with female residents (p=.017), and was not associated with other participant characteristics.

CONCLUSION

Intake was associated with dyadic verbal interactions, and such relationship was complex in that it was moderated by food type and video duration. Findings support the significant role of dyadic verbal interactions on intake, and inform the development of effective, tailored mealtime care interventions to promote intake.

Overview of systematic reviews: Effectiveness of non-pharmacological interventions for eating difficulties in people with dementia

AIM

To evaluate the effectiveness of non-pharmacological interventions for eating difficulties in people with dementia (PWD).

BACKGROUND

Eat difficulties are common problems in PWD. Prolonged eating difficulties may lead to inadequate/excessive food and drink intake and other adverse outcomes.

DESIGN

Overview of systematic reviews.

DATA SOURCES

Cochrane Library, JBI Library, PubMed, Embase, CINAHL, PsycINFO, and Psychology and Behavioral Sciences Collection, CNKI, WANFANG, from inception up until 23 September 2019.

REVIEW METHODS

This overview was conducted in accordance with methodological recommendations of Cochrane. Two researchers independently selected studies based on inclusion criteria, extracted data, assessed eligible studies using AMSTAR 2 and GRADE system, and summarized the conclusions.

RESULTS

Eighteen systematic reviews were included. Some evidence showed that environmental modifications, education/training, and Oral nutrition supplements (ONS) were beneficial to improving eating difficulties. But the current evidence failed to support the effectiveness of other interventions.

CONCLUSION

The overall confidence of systematic reviews is relatively low. High-quality studies are needed to further validate the effectiveness of non-pharmacological interventions for eating difficulties in PWD.

IMPACT

This overview provides evidence on the effectiveness of non-pharmacological interventions for eating difficulties in PWD. It will guide caregivers to choose more effective interventions to cope with eating difficulties and reduce the risk of adverse outcomes.

What nursing home environment can maximise eating independence among residents with cognitive impairment? Findings from a secondary analysis

To explore the influence of the Nursing Home (NH) environment on eating independence while taking into account individual and nursing care factors, was the aim of the study. A secondary analysis was performed based on data collected in a multicentre prospective observational study involving 13 NHs. Residents aged >65 were included (n = 1,027). Dependence in eating was measured using the Edinburgh Feeding Evaluation in Dementia scale (EdFED, range 0-20). In addition to individual and nursing care variables, the NHs environments were assessed with the Therapeutic Environment Screening Survey for Nursing Homes (TESS-NH, range 0-149). The mean EdFED score was 2.48 (95% Confidence Interval [CI]=2.22-2.73) and the TESS-NH score was 122.19 (95% CI=115.89-128.49). A linear regression analysis explained 30.8% of the total variance in eating dependence. Alongside individual and nursing care factors, in poor NH unit environments, residents with severe cognitive impairment showed increased eating dependence; in contrast, in better environments, similar residents showed maximal eating performance.

Eating performance in relation to intake of solid and liquid food in nursing home residents with dementia: A secondary behavioral analysis of mealtime videos

BACKGROUND

Persons with dementia commonly experience low food intake leading to negative nutritional and functional outcomes. While multilevel personal and environmental factors that influence intake are implicated, evidence is lacking on the role of characteristics of dynamic eating performance cycles. An eating performance cycle is defined as the process of getting food from the plate or container, transporting it into the mouth, and chewing and swallowing it.

OBJECTIVE

This study aimed to examine the association between intake and characteristics of eating performance cycles among nursing home residents with dementia.

METHODS

A secondary analysis of 111 mealtime video clips from a nursing home communication training study was conducted. The 111 videos involved 25 residents and 29 staff (N = 42 unique staff-resident dyads) in 9 nursing homes. The Cue Utilization and Engagement in Dementia Mealtime video-coding scheme was used to code the characteristics of eating performance cycles, including eating technique (resident-completed, staff-facilitated), type of food (solid, liquid), duration of each eating performance cycle, and intake outcome (intake, no intake). The Generalized Linear Mixed Model was used to examine the interaction effects of eating technique by type of food, eating technique by duration, and type of food by duration on intake outcome.

RESULTS

Totally 1122 eating performance cycles were coded from 111 video clips. The majority of the cycles (85.7%) resulted in intake. There were significant interactions for eating technique by duration, and type of food by duration. As the duration of the eating performance cycle increased, staff-facilitated cycles resulted in greater odds of intake than resident-completed cycles (OR = 17.80 vs. 2.73); and cycles involving liquid food resulted in greater odds of intake than cycles involving solid food (OR = 15.42 vs. 3.15). Though the interaction between eating technique and type of food was not significant, the odds of intake were greater for resident-completed cycles than for staff-facilitated cycles regardless of the type of food being involved in the cycle (OR = 3.60 for liquid food, OR = 10.69 for solid food).

CONCLUSIONS

The findings pointed out the importance of supporting resident independence in eating performance, providing liquid food when residents struggle with solid food, and provision of longer and continuous facilitation at mealtimes to improve intake. The findings inform the development and implementation of innovative mealtime assistance and staff training to promote eating performance and intake.

Planning for an uncertain future in progressive neurological disease: a qualitative study of patient and family decision-making with a focus on eating and drinking

BACKGROUND

Dysphagia and other eating and drinking difficulties are common in progressive neurological diseases. Mealtimes can become a major source of difficulty and anxiety for patients and their families. Decisions about eating, drinking and care can become challenging as disease progresses, and the person in question loses the capacity to participate in decisions about their own care. We sought to investigate how patients and their family members make decisions about their future care as their condition deteriorates, with a particular focus on mealtimes, eating and drinking.

METHODS

Longitudinal qualitative in-depth interviews were undertaken with patients and their family members (N = 29) across a range of disease groups, including: dementia, Parkinson's Disease, Huntington's Disease, Progressive Supranuclear Palsy, Motor Neurone Disease, Multiple Sclerosis. Patients had varying degrees of eating and drinking difficulties, and levels of decision-making capacity. Interviews were 'participant led' and undertaken in the patients' own homes or a place of their choosing. Follow-up interviews were three months to one year later depending upon disease trajectory. Interviews were audio recorded and analysed in NVivo using a Thematic Analysis approach.

RESULTS

Twenty-nine participants were interviewed between 2015 and 2017. Two key themes emerged from the analysis: 1) Health Literacy: the extent to which patients and relatives appeared to know about the condition and its treatment. Patients and their family members varied in their ability to speak and communicate about their condition and prognosis. 2) Planning style: the extent to which participants appeared to value involvement in advance care-planning. Patients and their family members varied in the way in which they made decisions: some preferred to 'take each day as it comes', while others wished to plan extensively for the future.

CONCLUSIONS

Issues with eating and drinking are often overlooked. Clinicians need to understand both the patient's level of health literacy and their style of planning before communicating with patients and their families about these sensitive issues.

Validation of the Spanish version of the Edinburgh Feeding Evaluation in Dementia Scale for older people with dementia

AIMS

To adapt the Edinburgh Feeding Evaluation in Dementia Scale (EdFED) for use in a Spanish-speaking population and to assess its validity and reliability in patients with dementia.

METHOD

A cross-sectional study was carried out in two stages: 1. Cross-cultural adaptation (translation, back-translation, review by committee of experts, pilot test and weighting of results); 2. Clinimetric validation comprising interobserver reliability assessment, test-retest reliability and internal consistency. To determine construct validity, confirmatory factorial analysis and principal components analysis were performed by oblique rotations. Criteria validity was analysed using the Pearson correlation (p<0.05) with the BMI, MNA and analytical values of albumin, transferrin, cholesterol, absolute lymphocytes and total proteins. Data collection was carried out for six months in 2016 in nursing homes and Alzheimer's day centers in the province of Málaga (Spain), at nine centers, with 262 patients (aged over 60 years and presenting feeding difficulties), 20 nurses, 20 professional caregivers and 103 family caregivers.

RESULTS

A version of EdFED culturally adapted to Spanish was obtained. The sample presented the following characteristics: 76.3% women, mean age 82.3 years (SD: 7.9); MNA 18.73 (SD: 4.44); BMI 23.99 (SD: 4.72); serum albumin 3.79 mg/dl (SD: 0.36). A Cronbach's alpha of 0.88 was obtained, with an inter-item global correlation of 0.43 and a homogeneity index ranging from 0.42 to 0.73. The exploratory factor analysis reproduced the three-factor model identified by the original authors, explaining 62.32% of the total variance. The criterion validity showed a good inverse correlation with MNA and a moderate one with albumin, total proteins, transferrin and BMI.

DISCUSSION

The Spanish version of EdFED is reliable and valid for use in elderly people with dementia. The most appropriate for our environment is the three-factor model, which maintains the original factors, with a slight redistribution of the items.
