Beliefs about inevitable decline among home-living older adults at risk of malnutrition: a qualitative study

Neurological recovery rate and predictive factors of incomplete AIS grade C spinal cord injury in the older aged population

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

To define the prognosis and predictive factors for neurological improvement in older patients with incomplete spinal cord injury (SCI) of American Spinal Injury Association Impairment Scale grade C (AIS-C).

SETTINGS

Multi-institutions in Japan.

METHODS

We included patients aged ≥65 years with traumatic SCI of AIS-C who were treated conservatively or surgically with >3 follow-up months. To identify factors related to neurological improvement, patients were divided into three groups according to their neurological status at the final follow-up, with univariate among-group comparisons of demographics, radiographic, and therapeutic factors. Significant variables were included in the multivariate logistic regression analysis.

RESULTS

Overall, 296 older patients with SCI of AIS-C on admission were identified (average age: 75.2 years, average follow-up: 18.7 months). Among them, 190 (64.2%) patients improved to AIS-D and 21 (7.1%) patients improved to AIS-E at final follow-up. There were significant among-group differences in age (p = 0.026), body mass index (p = 0.007), status of pre-traumatic activities of daily living (ADL) (p = 0.037), and serum albumin concentrations (p = 0.011). Logistic regression analysis showed no significant differences in variables in the stratified group of patients who improved to AIS-D. Meanwhile, serum albumin was a significant variable in patients who improved to AIS-E (p = 0.026; OR: 6.20, pre-traumatic ADL was omitted due to data skewness).

CONCLUSIONS

Most older patients with incomplete AIS-C SCI demonstrated at least 1 grade of neurological improvement. However, <10% of patients achieved complete recovery. Key predictors of complete recovery were high serum albumin levels on admission and independent pre-traumatic ADL.

Impact of malnutrition on mortality and neurological recovery of older patients with spinal cord injury

This retrospective cohort study established malnutrition's impact on mortality and neurological recovery of older patients with cervical spinal cord injury (SCI). It included patients aged ≥ 65 years with traumatic cervical SCI treated conservatively or surgically. The Geriatric Nutritional Risk Index was calculated to assess nutritional-related risk. Overall, 789 patients (mean follow-up: 20.1 months) were examined and 47 had major nutritional-related risks on admission. One-year mortality rate, median survival time, neurological recovery, and activities of daily living (ADL) at 1 year post-injury were compared between patients with major nutrition-related risk and matched controls selected using 1:2 propensity score matching to adjust for age, pre-traumatic neurological impairment, and activity. In the Kaplan-Meier analysis, the median survival times were 44.9 and 76.5 months for patients with major nutrition-related risk and matched controls, respectively (p = 0.015). Matched controls had more individuals with a neurological improvement of American Spinal Injury Association Impairment Scale ≥ 1 grade (p = 0.039) and independence in ADL at 1 year post-injury than patients with major nutrition-related risk (p < 0.05). In conclusion, 6% of older patients with cervical SCI had major nutrition-related risks; they showed a significantly higher 1 year mortality rate, shorter survival time, poorer neurological improvement, and lower ADL at 1 year post-injury than matched controls.

The Malnutrition Awareness Scale for community-dwelling older adults: Development and psychometric properties

BACKGROUND & AIMS

Qualitative studies suggest that malnutrition awareness is poor in older adults. The aim of this study was to develop a questionnaire to quantitatively assess malnutrition awareness in community-dwelling older adults aged 60+ years.

METHODS

The Malnutrition Awareness Scale (MAS) was developed based on the awareness phase of the Integrated-Change model, and included four domains: knowledge, perceived cues, risk perceptions, and cognizance. Twenty-six scale items were developed using results from mainly qualitative research and the expertise of the authors. Items were piloted in 10 Dutch older adults using the Thinking Aloud method to optimize wording. In a feasibility study, annoyance, difficulty and time to complete the MAS and its comprehensibility were tested. After final revisions, the MAS was applied to a large sample to test its psychometric properties (i.e., inter-item correlations, Cronbach's alpha, score distribution) and relevance of the items was rated on a 5-point scale by 12 experts to determine content validity.

RESULTS

The feasibility study (n = 42, 55 % women, 19 % 80+ y) showed that the MAS took 12 ± 6 min to complete. Most participants found it not (at all) annoying (81 %) and not (at all) difficult (79 %) to complete the MAS, and found it (very) comprehensible (83 %). Psychometric analyses (n = 216, 63 % women, 28 % 80+ y) showed no redundant items, but two items correlated negatively with other items, and one correlated very low. After removal, the final MAS consists of 23 items with a min-max scoring range from 0 to 22 (with higher scores indicating higher awareness) and an overall Cronbach's alpha of 0.67. The mean MAS score in our sample (n = 216) was 14.8 ± 3.2. The lowest obtained score was 6 (n = 3) and the highest 22 (n = 1), indicating no floor or ceiling effects. Based on the relevance rating, the overall median across all 22 items was 4.0 with IQR 4.0-5.0.

CONCLUSION

The Malnutrition Awareness Scale is a novel, feasible and reliable tool with good content validity to quantitively assess malnutrition awareness in community-dwelling older adults. The scale is now ready to identify groups with poor malnutrition awareness, as a basis to start interventions to increase malnutrition knowledge and awareness.

Dietitians' perceptions of identifying and managing malnutrition and frailty in the community: A mixed-methods study

AIM

This study aimed to explore dietitians' perceptions of their current practice for identifying and managing malnutrition/frailty in the community, to fill an evidence gap.

METHODS

This mixed-methods study involved an online survey distributed to dietitians practising in Australia and New Zealand, and semi-structured interviews with a subset of survey participants. The 34-item survey and interviews explored dietitians' practices for identifying/managing malnutrition and frailty, focusing on the community setting. Survey data were analysed descriptively and some simple association tests were conducted using statistical software. Interview data were analysed thematically.

RESULTS

Of the 186 survey respondents, 18 also participated in an interview. Screening and assessment for malnutrition varied in the community and occurred rarely for frailty. Dietitians reported practising person-centred care by involving clients/carers/family in setting goals and selecting nutrition interventions. Key barriers to providing nutrition care to community-dwelling adults included a lack of awareness/understanding of nutrition by clients and other health professionals (leading to them not participating in or valuing nutrition care), lack of time and resources in the community, and client access to foods/supplements. Enablers included engaging family members/carers and coordinating with other health professionals in nutrition care planning.

CONCLUSION

Reported practices for identifying malnutrition and frailty vary in the community, suggesting guidance may be needed for health professionals in this setting. Dietitians reported using person-centred care with malnourished and frail clients but encountered barriers in community settings. Engaging family members/carers and multidisciplinary colleagues may help overcome some of these barriers.

Prevention, identification and management of malnutrition in older people in the community

Malnutrition, specifically undernutrition, is a significant health concern among older people, yet it is under-detected and under-treated in the community. The causes of malnutrition are complex and multifactorial, and the risk has been exacerbated by the coronavirus disease 2019 (COVID-19) pandemic due to social isolation and loneliness, which can affect older people's appetite and thus reduce their nutritional intake. This article discusses the causes and consequences of malnutrition in older people and describes what is involved in malnutrition screening, person-centred care planning and treatment. The author considers various approaches to overcoming the barriers associated with identifying malnutrition in older people in the community and outlines the role of the nurse in the effective management of malnutrition in this population.

Advances in knowledge of screening practices and their use in clinical practice to prevent malnutrition

Malnutrition is common among older adults and is associated with a progressive decline in overall health and increased mortality. With a rapidly ageing population, the detection, prevention and management of malnutrition require urgent attention within health service planning and delivery. Routine screening for malnutrition among older adults in community settings, which addresses aetiological as well as phenotypic factors, is considered an important step for prevention and early intervention. The aim of this review is to summarise current malnutrition screening literature and highlight research that seeks to understand and address community-based approaches to malnutrition screening and management. Key healthcare professionals (HCPs) that encounter community-dwelling older adults include general practitioners (GPs), community-based nurses, community pharmacists and a range of other health and social care professionals including dietitians, physiotherapists, speech and language therapists, and occupational therapists. The key barriers to implementing screening in primary care include lack of knowledge about malnutrition among non-dietetic HCPs, lack of resources allocated to managing malnutrition, lack of access to dietetic services, and poor GP knowledge about oral nutritional supplement prescribing. In addition, older adults have poor insight into the clinical condition and the associated negative health implications. Investment in education among HCPs and public awareness is required, as well as accompanying resources to successfully implement malnutrition screening programmes for community-dwelling older adults.

Optimising an intervention to support home-living older adults at risk of malnutrition: a qualitative study

Background

In the UK, about 14% of community-dwelling adults aged 65 and over are estimated to be at risk of malnutrition. Screening older adults in primary care and treating those at risk may help to reduce malnutrition risk, reduce the resulting need for healthcare use and improve quality of life. Interventions are needed to raise older adults’ risk awareness, offer relevant and meaningful strategies to address risk and support general practices to deliver treatment and support.

Methods

Using the Person-based Approach and input from Patient and Public Involvement representatives, we developed the ‘Eat well, feel well, stay well’ intervention. The intervention was optimised using qualitative data from think aloud and semi-structured process evaluation interviews with 23 and 18 older adults respectively. Positive and negative comments were extracted to inform rapid iterative modifications to support engagement with the intervention. Data were then analysed thematically and final adjustments made, to optimise the meaningfulness of the intervention for the target population.

Results

Participants’ comments were generally positive. This paper focuses predominantly on participants’ negative reactions, to illustrate the changes needed to ensure that intervention materials were optimally relevant and meaningful to older adults. Key factors that undermined engagement included: resistance to the recommended nutritional intake among those with reduced appetite or eating difficulties, particularly frequent eating and high energy options; reluctance to gain weight; and a perception that advice did not align with participants’ specific personal preferences and eating difficulties. We addressed these issues by adjusting the communication of eating goals to be more closely aligned with older adults’ beliefs about good nutrition, and acceptable and feasible eating patterns. We also adjusted the suggested tips and strategies to fit better with older adults’ everyday activities, values and beliefs.

Conclusions

Using iterative qualitative methods facilitated the identification of key behavioural and contextual elements that supported engagement, and issues that undermined older adults’ engagement with intervention content. This informed crucial revisions to the intervention content that enabled us to maximise the meaningfulness, relevance and feasibility of the key messages and suggested strategies to address malnutrition risk, and therefore optimise engagement with the intervention and the behavioural advice it provided.

The effectiveness of nutrition interventions in improving frailty and its associated constructs related to malnutrition and functional decline among community-dwelling older adults: A systematic review

BACKGROUND

The present study aimed to evaluate the effectiveness of nutrition interventions on frailty and factors related to frailty, including malnutrition, sarcopenia and functional ability, among community dwelling older adults. A secondary aim was to synthesise current clinical guidelines for the identification and management of frailty, and then identify whether they aligned with the findings of the literature review.

METHODS

A systematic literature review was undertaken using four electronic databases to identify randomised controlled clinical trials that assessed the effect of nutrition interventions on frailty and outcomes related to frailty in community-dwelling older adults (PROSPERO #CRD42017069094). The quality of the included studies was appraised. A rapid review was conducted using the Google Scholar database to identify existing clinical recommendations relating to the second aim.

RESULTS

The search strategy identified 13 studies. Multifactorial interventions with nutritional education and protein-energy supplementation improved frailty stratus and physical performance in 75% and 58% of studies, respectively. Weight and nutritional status improved in 80% of studies that used oral nutritional support. The recommended process for clinical management of frailty involves screening, followed by full assessment using validated instruments and the development of a comprehensive management plan with a multidisciplinary team.

CONCLUSIONS

Multifactorial interventions were found to be more effective than nutrition intervention alone for improving frailty and physical performance. Protein-energy supplementation tended to be effective only in malnourished older adults. The results were inconclusive for the use of micronutrient supplementation for frailty and outcomes related to frailty. Existing clinical guidelines are aligned with the evidence recommending comprehensive interventions to improve frailty.

Older individual's perceptions of appetite, its loss, influencing factors and adaptions to poor appetite. A qualitative study

Appetite loss in later life is common and associated with malnutrition; however, there is limited knowledge on older individuals' perspectives of appetite. This study aimed to explore what 'appetite' means to older adults, how they experience its change and perceived influences on this experience. Semi-structured interviews were conducted with thirteen participants, aged ≥65 years, in their own home, following a recent arm fracture. Transcripts were analysed using reflexive thematic analysis with inductive coding resulting in three themes. 1. 'Appetite as an emotional experience' encompassed positive or negative thoughts and feelings driving or undermining desire to eat. Mood, the appeal of food, cooking and effects of interaction and experiences with other people were factors in this narrative. 2. 'Appetite reflects a physical need' comprised physical bodily sensations or requirements as a driver for appetite with poor appetite resulting from early or over fullness. Declines with age, illness and less activity, were factors in this narrative. 3. 'Adaption to poor appetite aligns with perception of appetite and wider physical health' accounts for how experiential strategies, or practical strategies were used to mitigate poor appetite depending on the narrative of appetite loss, alongside perceptions of physical health and unplanned weight loss. Most individuals used one narrative in their discussions and reflections but for some, perceptions of appetite and its change were more complex. Understanding relationships between these perceptions of appetite and influential factors could facilitate development of multi-component, person-centred, strategies that are optimally meaningful and relevant to address appetite loss in later life.

'It takes a village': a qualitative study on malnutrition and oral nutritional supplements with older adults in Ireland

BACKGROUND

Malnutrition affects approximately 20% of older adult populations in Europe, yet their views on the condition are rarely explored. This qualitative study aimed to explore the experiences of older adults living with malnutrition and prescribed oral nutritional supplements in the community setting.

METHODS

Semi-structured individual interviews were used to collect data from 13 community-dwelling individuals aged ≥60 years with a current or previous prescription for oral nutritional supplements. Self-perceived health status was measured using the EuroQol EQ-5D-5L, a short questionnaire and visual analogue scale. Interviews were audio-recorded and transcribed verbatim. Interview data were organized using NVivo 12 and analyzed using inductive thematic analysis.

RESULTS

Median age was 80.0 (interquartile range 19.5) years, seven were male and six were female. Median health score was 60.0 (interquartile range 35.0) out of 100. Almost one-third reported severe or extreme problems with usual activities, and pain or discomfort. One main theme was identified from the interviews: 'It takes a village', with four subthemes (i) 'I get by with a little help from my friends', (ii) 'The obvious diagnosis', (iii) 'The missing T in MDT' and (iv) 'Confusion'. Participants with malnutrition reported relying on friends, family and carers with poor multidisciplinary team communication and lack of dietetic support.

CONCLUSIONS

Participants in this study experienced poor management of malnutrition with missing links between the hospital and community healthcare settings, and lack of dietetic services. Patient views should be used to inform public health guidelines and guide future interventions in the community to improve the health status of older adults with malnutrition.

Managing malnutrition in the community during the COVID-19 pandemic

The prevalence of risk factors for malnutrition has increased during the coronavirus disease 2019 (COVID-19) pandemic. These risk factors include various symptoms and effects of COVID-19, such as breathlessness, coughing, inflammation, sarcopenia, anorexia and loss of taste or smell, as well as the side effects of treatment. In addition, public health infection prevention and control measures can inadvertently reduce access to food and increase social isolation, thus adversely affecting people's nutritional status. This article outlines practical interventions for preventing and managing malnutrition in the community, particularly where it is exacerbated by the social restrictions in place to contain the COVID-19 pandemic.
