A palliative care goals model for people with dementia and their family: Consensus achieved in an international Delphi study.

BACKGROUND: Advance care planning in dementia includes supporting the person and their family to consider important goals of care. International research reports the importance of psycho-social-spiritual aspects towards end of life. AIM: To develop a multidimensional international palliative care goals model in dementia for use in practice. DESIGN: International Delphi study integrating consensus and evidence from a meta-qualitative study. The Delphi panel rated statements about the model on a 5-point agreement scale. The criteria for consensus were pre-specified. SETTING/PARTICIPANTS: Seventeen researchers from eight countries developed an initial model, and 169 candidate panellists were invited to the international online Delphi study. RESULTS: Panellists (107; response 63.3%) resided in 33 countries. The model comprised four main care goals: (1) Comfort ensured; (2) Control over function maintained; (3) Identity protected and personhood respected and (4) Coping with grief and loss-person and caregiver supported. The model reflects how needs and care goals change over time with the progression of dementia, concluding with bereavement support. The first version of the model achieved a consensus after which it was slightly refined based on feedback. We did not achieve a consensus on adding a goal of life prolongation, and on use of the model by people with dementia and family themselves. CONCLUSION: A new palliative care goals model for people with dementia and their families includes relationship aspects for use by professionals and achieved a consensus among a panel with diverse cultural background. The position of life prolongation in relation to palliative care goals needs further research.

Observational learning of threat-related attentional bias.

Attentional bias to threat has been almost exclusively examined after participants experienced repeated pairings between a conditioned stimulus (CS) and an aversive unconditioned stimulus (US). This study aimed to determine whether threat-related attentional capture can result from observational learning, when participants acquire knowledge of the aversive qualities of a stimulus without themselves experiencing aversive outcomes. Non-clinical young-adult participants (N = 38) first watched a video of an individual (the demonstrator) performing a Pavlovian conditioning task in which one colour was paired with shock (CS+) and another colour was neutral (CS-). They then carried out visual search for a shape-defined target. Oculomotor measures evidenced an attentional bias toward the CS+ colour, suggesting that threat-related attentional capture can ensue from observational learning. Exploratory analyses also revealed that this effect was positively correlated with empathy for the demonstrator. Our findings extend empirical and theoretical knowledge about threat-driven attention and provide valuable insights to better understand the formation of anxiety disorders.

Effects of physical activity on depressive symptoms in older caregivers: The IMPACCT randomized controlled trial.

OBJECTIVES: Physical activity (PA) can reduce depressive symptoms but has not been tested amongst depressed older caregivers and their care-recipients. The aim of this single-blind randomized controlled trial was to investigate the effect of a 6-month tailored PA program on depressive symptoms in older caregivers. METHOD: Caregivers were included if they had scores of ≥5 on the 15-item geriatric depression scale (GDS-15). Care-recipients could have any type of physical, mental or cognitive condition requiring support. The PA intervention group completed an individualized program based on the Otago-Plus Exercise Program. The primary outcome was improvement in depressive symptoms in caregivers measured at six and 12 months. RESULTS: Two hundred and twelve participants (91 dyads and 30 caregivers only) were randomized using a 3:3:1 ratio to PA intervention, social-control, and usual-care control groups. There were no significant differences in depressive symptoms of the caregivers between the three groups at 6 months or 12 months. However, more than 50% of caregivers in all three groups no longer had a GDS-15 score ≥5 at 6 months. Further analysis revealed that caregivers in the PA group caring for someone with a standardised mini-mental state examination (SMMSE) score ≥24 had significantly less depressive symptoms than those caring for someone with a SMMSE score <24 compared with social-control (p < 0.02) and usual-care groups (p < 0.02). CONCLUSIONS: A PA intervention may be beneficial for some caregivers in reducing symptoms of depression but may not be as beneficial to caregivers of people living with cognitive impairment.

Lessons learnt from a community-driven digital social connection pilot program for people living with dementia: A qualitative interview study with key stakeholders.

INTRODUCTION: In response to COVID-19 and mandated physical distancing, a new digital social connection program was developed and implemented by the local community in a large regional town in western Victoria, Australia. This pilot program, the Digital Inclusion-Social Connections (DI-SC) program, aimed to support people living with dementia to use a digital device to access social connection activities. OBJECTIVE: The objective of this study is to inform the local community implementing the DI-SC program of key stakeholder experience of DI-SC process and outcomes to support future development and potential translation of digital social connections programs for people living with dementia. DESIGN: Three semi-structured focus groups and two interviews were conducted with a total of fifteen participants. Data was transcribed verbatim and thematically analysed. FINDINGS: Three main themes were identified describing factors as influencing the process and outcomes of the DI-SC program: understanding dementia; personal choice and control; and service planning and coordination. Six sub-themes were identified: matching capability; establishing a relationship; creating opportunities for different interactions; ownership of the device, program coordination and defining the volunteer digital mentor role. CONCLUSION: Key stakeholders perceived the DI-SC program as an acceptable way of supporting people living with dementia to engage in activities they found enjoyable promoting social connection with care partners and others. DI-SC program outcomes were impacted by inappropriate training and a lack of program coordination. The findings of this study may inform future development and implementation of digital social connection programs for vulnerable populations at risk of social isolation.

Assessment of revascularization impact on microvascular oxygenation and perfusion using spatial frequency domain imaging.

The microvasculature (with vessels <100 µm in diameter) plays a crucial role in tissue oxygenation, perfusion and wound healing in the lower limb. While this holds clinical significance, microvasculature evaluation in the limbs is not a standard practice. Surgical interventions focus on reestablishing blood flow in larger vessels affected by the peripheral artery disease (PAD). Nevertheless, the impact of revascularization on tissue oxygenation and perfusion in severe microvascular disease (MVD) is still unknown. We present the cases of two patients who underwent surgical revascularization for peripheral blood flow with different outcomes. Patient A had PAD, while B had PAD, severe MVD and a non-healing wound. Although both showed improvements in ankle-brachial index post-op, spatial frequency domain imaging metrics (which measure microvascular oxygenation and perfusion) remained unchanged in B, indicating a potential gap in assessing the surgical efficacy in MVD using ankle brachial index and emphasizing microcirculation evaluation in optimizing wound healing outcomes.

A mixed methods evaluation of a program exploring predeath grief and loss for carers of people with rarer dementias.

OBJECTIVES: Predeath grief conceptualizes complex feelings of loss experienced for someone who is still living and is linked to poor emotional well-being. The Road Less Travelled program aimed to help carers of people with rarer dementias identify and process predeath grief. This study evaluated the feasibility, acceptability, and preliminary effectiveness of this program. DESIGN: Pre-post interventional mixed methods study. SETTING: Online videoconference group program for carers across the UK held in 2021. PARTICIPANTS: Nine family carers of someone living with a rare form of dementia. Eight were female and one male (mean age 58) with two facilitators. INTERVENTION: The Road Less Travelled is an online, facilitated, group-based program that aims to help carers of people with rarer dementias to explore and accept feelings of grief and loss. It involved six fortnightly 2-hour sessions. MEASUREMENTS: We collected measures for a range of well-being outcomes at baseline (T1), post-intervention (T2), and 3 months post-intervention (T3). We conducted interviews with participants and facilitators at T2. RESULTS: Participant attendance was 98% across all sessions. Findings from the semistructured interviews supported the acceptability of the program and identified improvements in carer well-being. Trends in the outcome measures suggested an improvement in quality of life and a reduction in depression. CONCLUSION: The program was feasible to conduct and acceptable to participants. Qualitative reports and high attendance suggest perceived benefits to carers, including increased acceptance of grief, and support the need for a larger-scale pilot study to determine effectiveness.

Exploring how family carers of a person with dementia manage pre-death grief: A mixed methods study.

OBJECTIVES: Many family carers of a person with dementia experience pre-death grief. We aimed to identify strategies that help carers manage pre-death grief. We hypothesised that emotion and problem focussed styles would be associated with lower, and dysfunctional coping with higher grief intensity. METHODS: Mixed methods observational study using structured and semi-structured interviews with 150 family carers of people with dementia living at home or in a care home. Most participants were female (77%), caring for a parent (48%) or partner/spouse (47%) with mild (25%), moderate (43%) or severe (32%) dementia. They completed the Marwit-Meuser Caregiver Grief Inventory Short Form and the Brief Coping Orientation to Problems Experienced (Brief-COPE) questionnaire. We asked carers to identify strategies used for managing grief. We recorded field notes for 150 interviews and audio-recorded additional interviews with a sub-sample of 16 participants. RESULTS: Correlations indicated that emotion-oriented coping was associated with lower grief (R = -0.341), and dysfunctional coping with higher grief (R = 0.435), with a small association with problem-focused strategies (R = -0.109), partly supporting our hypothesis. Our qualitative themes broadly match the three Brief-COPE styles. Unhelpful strategies of denial and avoidance align with dysfunctional coping strategies. Psychological strategies (including acceptance and humour) and seeking support were consistent with emotion-focused strategies, but we did not identify a theme relating to problem-focused strategies. CONCLUSION: Most carers identified multiple strategies for processing grief. Carers could readily identify supports and services that they found helpful for managing pre-death grief, yet current services appear under-resourced to meet growing demand.

Grief in family carers of people living with dementia: A systematic review.

OBJECTIVES: Grief research in family carers of people with dementia has increased. We aimed to report the prevalence of pre-death and post-death grief and to synthesize associated factors and the relationship between pre-death factors and post-death grief and services used to manage grief. DESIGN: (Prospero protocol: CRD42020165071) We systematically reviewed literature from PsycINFO, MEDLINE, CINAHL, and ASSIA until April 2020. Effectiveness of intervention data and studies not written in English were excluded; qualitative studies were additionally excluded during study selection. Study quality was assessed using the Mixed Methods Appraisal Tool. Evidence was narratively summarized. PARTICIPANTS: Family non-paid carers of somebody with any dementia type. MEASUREMENTS: Validated measures of pre-death and/or post-death grief. RESULTS: We included quantitative data from 55 studies (44 rated as high quality). Most included solely spouse or adult child carers. Forty-one studies reported pre-death grief, 12 post-death grief, and 6 service use; eight were longitudinal. 17% met the Prolonged Grief Disorder criteria pre-death (n = 1) and 6-26% (n = 4) of participants met the Complicated Grief criteria post-death. Being a spouse, less educated, caring for somebody with advanced dementia, and greater burden and depression were associated with higher pre-death grief. Lower education level and depression were predictive of higher post-death grief. Pre-death factors found to influence post-death grief were grief and depression. Limited service use evidence was reported. CONCLUSION: Awareness of characteristics which increase the likelihood of higher grief can help identify those in need of support. Future research should focus on what supports or services are beneficial to grief experiences.

The Development of Videoconference-Based Support for People Living With Rare Dementias and Their Carers: Protocol for a 3-Phase Support Group Evaluation.

BACKGROUND: People living with rarer dementias face considerable difficulty accessing tailored information, advice, and peer and professional support. Web-based meeting platforms offer a critical opportunity to connect with others through shared lived experiences, even if they are geographically dispersed, particularly during the COVID-19 pandemic. OBJECTIVE: We aim to develop facilitated videoconferencing support groups (VSGs) tailored to people living with or caring for someone with familial or sporadic frontotemporal dementia or young-onset Alzheimer disease, primary progressive aphasia, posterior cortical atrophy, or Lewy body dementia. This paper describes the development, coproduction, field testing, and evaluation plan for these groups. METHODS: We describe a 3-phase approach to development. First, information and knowledge were gathered as part of a coproduction process with members of the Rare Dementia Support service. This information, together with literature searches and consultation with experts by experience, clinicians, and academics, shaped the design of the VSGs and session themes. Second, field testing involved 154 Rare Dementia Support members (people living with dementia and carers) participating in 2 rounds of facilitated sessions across 7 themes (health and social care professionals, advance care planning, independence and identity, grief and loss, empowering your identity, couples, and hope and dementia). Third, a detailed evaluation plan for future rounds of VSGs was developed. RESULTS: The development of the small groups program yielded content and structure for 9 themed VSGs (the 7 piloted themes plus a later stages program and creativity club for implementation in rounds 3 and beyond) to be delivered over 4 to 8 sessions. The evaluation plan incorporated a range of quantitative (attendance, demographics, and geography; pre-post well-being ratings and surveys; psycholinguistic analysis of conversation; facial emotion recognition; facilitator ratings; and economic analysis of program delivery) and qualitative (content and thematic analysis) approaches. Pilot data from round 2 groups on the pre-post 3-word surveys indicated an increase in the emotional valence of words selected after the sessions. CONCLUSIONS: The involvement of people with lived experience of a rare dementia was critical to the design, development, and delivery of the small virtual support group program, and evaluation of this program will yield convergent data about the impact of tailored support delivered to geographically dispersed communities. This is the first study to design and plan an evaluation of VSGs specifically for people affected by rare dementias, including both people living with a rare dementia and their carers, and the outcome of the evaluation will be hugely beneficial in shaping specific and targeted support, which is often lacking in this population.

Cross-cultural conceptualization of a good end of life with dementia: a qualitative study.

BACKGROUND: Research on the nature of a "good death" has mostly focused on dying with cancer and other life-limiting diseases, but less so on dementia. Conceptualizing common cross-cultural themes regarding a good end of life in dementia will enable developing international care models. METHODS: We combined published qualitative studies about end of life with dementia, focus group and individual interviews with the researchers, and video-conferencing and continuous email discussions. The interviews were audio-recorded and transcribed verbatim. The data were analyzed thematically, and the researchers developed common themes referring to their original studies. RESULTS: Fourteen qualitative researchers representing 14 cross-cultural studies covering qualitative data of 121 people with dementia and 292 family caregivers. The researchers and data were from eight countries UK, The Netherlands, Japan, Portugal, Germany, Canada, Brazil, and Ireland. Three focus groups, five individual interviews, and video-conferencing were conducted and feedback on multiple iterations was gained by 190 emails between May 2019 and April 2020 until consensus was achieved. Nine cross-culturally common themes emerged from the discussions and shared interpretation of the data of persons with dementia and family caregivers. Three represent basic needs: "Pain and Symptoms Controlled," "Being Provided Basic Care," and "A Place like Home." Other themes were "Having Preferences Met," "Receiving Respect as a Person," "Care for Caregivers," "Identity Being Preserved," "Being Connected," and "Satisfaction with Life and Spiritual Well-being." "Care for Caregivers" showed the greatest difference in emphasis across cultures. Good relationships were essential in all themes. CONCLUSIONS: The common cross-cultural themes comprise a framework underpinned by value placed on personhood and dignity, emphasizing that interdependency through relationships is essential to promote a good end of life with dementia. These themes and valuing the importance of relationships as central to connecting the themes could support care planning and further development of a dementia palliative care model.

Experiences of Carers and People with Dementia from Ethnic Minority Groups Managing Eating and Drinking at Home in the United Kingdom.

Eating and drinking difficulties, such as loss of appetite and swallowing problems, are common in dementia, but little is known about the experiences of ethnic minority groups who are managing these difficulties at home. The purpose of our study was to explore the meaning of food, the impact of dementia on eating and drinking, and carers' experiences of support. We undertook semi-structured interviews with 17 carers and people with dementia from ethnic minority backgrounds living in England, using thematic analysis to analyse the data. Food/drink had strong links to identity, culture and emotions. Providing culturally familiar foods, celebrating traditional festivals and supporting previous food-related roles promoted reminiscence, which encouraged the people living with dementia to eat and drink, as did social interactions, although these could lead to distress in those with more advanced dementia. Food choices were also influenced by carer strain, generational differences and the impact of health conditions. Despite a strong sense of duty to care for relatives at home, there was low awareness of community support services. The carers expressed a need for culturally tailored support for managing dementia-related eating and drinking difficulties at home. Healthcare professionals must provide contextually relevant advice to carers, being mindful of how cultural backgrounds can affect dietary choices.

Rapid development of a COVID-19 care planning decision-aid for family carers of people living with dementia.

INTRODUCTION: COVID-19 has disproportionately affected people living with dementia and their carers. Its effects on health and social care systems necessitated a rapid-response approach to care planning and decision-making in this population, with reflexivity and responsiveness to changing individual and system needs at its core. Considering this, a decision-aid to help families of persons with dementia was developed. OBJECTIVES: To coproduce with people living with dementia, and the people who care for them, a decision-aid for family carers of people living with dementia, to support decisions during the COVID-19 pandemic and beyond. METHODS: Semi-structured interviews were undertaken in 2020 with: (1) staff from two English national end-of-life and supportive care organizations; and (2) people living with dementia and family carers. Simultaneously, a rapid review of current evidence on making decisions with older people at the end of life was undertaken. Evidence from these inputs was combined to shape the decision-aid through a series of workshops with key stakeholders, including our patient and public involvement group, which consisted of a person living with dementia and family carers; a group of clinical and academic experts and a group of policy and charity leads. RESULTS: The rapid review of existing evidence highlighted the need to consider both process and outcome elements of decision-making and their effects on people living with dementia and their families. The qualitative interviews discussed a wide range of topics, including trust, agency and confusion in making decisions in the context of COVID-19. The decision-aid primarily focussed on care moves, legal matters, carer wellbeing and help-seeking. CONCLUSIONS: Combining different sources and forms of evidence was a robust and systematic process that proved efficient and valuable in creating a novel decision-aid for family carers within the context of COVID-19. The output from this process is an evidence-based practical decision-aid coproduced with people living with dementia, family carers, clinical and academic experts and leading national dementia and palliative care organizations. PATIENT OR PUBLIC CONTRIBUTION: We worked with people living with dementia and family carers and other key stakeholders throughout this study, from study development and design to inclusion in stakeholder workshops and dissemination.

How do factors of sociodemographic, health literacy and dementia experience influence carers' knowledge of dementia?

BACKGROUND: Dementia is a life limiting disease following a progressive trajectory. As carers often become key decision makers, their knowledge of dementia will have health implications for the person living with dementia as well as carer's psychological wellbeing. AIM: To explore how sociodemographic factors, health literacy and dementia experience influence family carers knowledge about dementia. METHOD: In this cross-sectional, mixed methods study, we interviewed 150 family carers and assessed their dementia knowledge using the Dementia Knowledge Assessment Scale (DKAS). Linear regression analyses were used to examine whether health literacy, previous experiences of dementia, support group attendance and sociodemographic characteristics predicted knowledge. Sixteen carers also completed qualitative interviews which explored unmet information needs. Transcripts and field notes were thematically analysed. RESULTS: Most participants were partners (47%) or adult children (48%) and cared for someone with severe (32%) or moderate (43%) dementia. Mean DKAS scores were 34.8/50 (SD = 7.0, range = 17-48) reflecting 8/25 incorrect answers. Backwards elimination regression found greater dementia knowledge was associated with greater health literacy for appraising information (coef 3.48, 95% CI (1.38, 5.58); p = 0.001) and more years of education (coef 0.39, 95% CI (0.12, 0.65); p = 0.004). Although not significant, knowledge was slightly lower in those who attended a support group, and a trend was found between ability to understand health information and knowledge. Only 39% accurately identified dementia as life shortening, indicating notable gaps in knowledge. Four qualitative themes were identified; arm yourself with information, ability to steer through information, other experience of dementia can be helpful and the importance of relationships with health care professionals. CONCLUSIONS: In an information age, vast amounts of information are available, but this can bring difficulties. Carers with more years of education and higher health literacy knew more about dementia. Professionals should consider how carers with lower health literacy can be supported through provision of timely, relevant information.

Practical and emotional preparation for death: A mixed methods study investigating experiences of family carers of people with dementia.

BACKGROUND: When family carers are more prepared for the end of the life of a person they care for, they report improved bereavement outcomes. Few studies have explored how carers prepare for the death of a person with dementia. We aimed to explore how carers for people with all stages of dementia experience preparing for end of life care and death. METHODS: This was a mixed methods cross-sectional study. Family carers of people with dementia (n = 150) completed a structured interview with validated scales, alongside questions about death preparedness and advance decisions. A sub-sample (n = 16) completed qualitative interviews exploring their experiences of planning for end of life. We fitted logistic regression models to explore associations with preparedness, and thematically analysed qualitative data. RESULTS: We addressed practical and emotional preparation separately for 143 participants. Fifty seven percent of participants were very practically prepared for death, while only 29% were very emotionally prepared. Male carers were more likely than female carers to report being very emotionally and practically prepared. Higher engagement with healthcare professionals was associated with feeling very practically prepared; although we found that formal discussions of end of life care issues with healthcare professionals did not impact carers' feelings of preparation. Higher levels of dementia severity and carer depression were associated with feeling very emotionally prepared. Three qualitative themes related to practical and emotional preparation were identified: (1) ambiguity and uncertainty; (2) support from the system; and (3) how death is perceived by the carer. CONCLUSIONS: While most carers felt practically prepared for death, emotional preparation was much lower. Further research is needed to understand how engagement with healthcare professionals or other forms of social or emotional support could help carers, particularly female carers, to emotionally prepare for their relative's death.

Family caregivers' and professionals' experiences of supporting people living with dementia's nutrition and hydration needs towards the end of life.

The aim of this paper was to understand the needs of family caregivers and professionals supporting people living with dementia with eating and drinking difficulties towards the end of life and the strategies they use to overcome them. A total of 41 semi-structured interviews with family caregivers (n = 21) and professionals (n = 20) were conducted in London and surrounding areas of England. Interviews were audio-recorded and transcribed verbatim. Four themes were identified: caregivers accessing and seeking help, perceived priorities of care, professionals' supportiveness and educational role, and strategies. Caregivers often struggle as they are not aware of the eating and drinking difficulties associated with dementia's progression. Care can change over time with families prioritising a person's comfort towards the end of life rather than ensuring a particular level of nutrition. Mutual support is required by both professionals and caregivers to enhance the care of the person living with dementia. Cognitive difficulties are often behind initial eating and drinking challenges in dementia, whereas physical challenges take over towards the later stages. Flexibility and creativity are key to adapting to changing needs. There is a need to raise awareness of the eating and drinking challenges associated with the progression of dementia. Professionals can help caregivers embark on the transition towards focussing on comfort and enjoyment of eating and drinking near the end of life rather than nutrition. This is particularly relevant for those caring for a relative living at home. Caregivers' input is needed to tailor professionals' recommendations.

Usefulness and acceptability of an animation to raise awareness to grief experienced by carers of individuals with dementia.

AIM: Many carers of individuals with dementia experience high levels of grief before and after the death of the person with dementia. This study aimed to determine the usefulness, acceptability, and relevance of an animation developed to raise awareness to grief experienced by carers of people with dementia. METHODS: This research had a cross-sectional survey design. We contacted carers of people with dementia over the phone or email. Participants evaluated the animation through an online or paper-based survey. We used descriptive statistics and analysed qualitative data using thematic analysis. We required a sample of 40 carers to adequately power the study with a target of 75% of carers finding the animation useful, acceptable, and relevant. RESULTS: 31/78 carers approached evaluated the animation. Ninety-four percent of participants found the animation relevant to their situation, meeting our target. However, we fell short of this target for usefulness (68%) and acceptability (73%). The qualitative responses suggested that participants felt the animation could help improve the understanding of grief among carers, family, friends, and healthcare professionals. Carers also shared that the animation would be most useful for carers of newly diagnosed people with dementia. CONCLUSION: Most carers of people with dementia in this study reported that the animation was useful, acceptable, and relevant. Dissemination of the resource may be useful for the majority of carers, with the caveat that a few carers may find it distressing and need to be referred for further support.

Challenges faced during the COVID-19 pandemic by family carers of people living with dementia towards the end of life.

BACKGROUND: People living with dementia account for a large proportion of deaths due to COVID-19. Family carers are faced with making significant and emotive decisions during the pandemic, including decisions about end of life. We aimed to explore the challenges faced by family carers of people living with dementia during the first wave of the COVID-19 pandemic in England, as reported by charity telephone support line staff, who were able to objectively discuss a range of different experiences of many different carers who call the helpline. In particular, we focussed on key concerns and areas of decision making at the end of life. METHODS: We conducted a qualitative study using semi-structured interviews with eight telephone support line staff from two UK based charities who support carers of people living with dementia and those at the end of life. Interviews were conducted in the first wave of the pandemic in England in May-June 2020. RESULTS: An overarching theme of uncertainty and reactivity during a crisis was identified, and within this, five main themes were identified: concerns about care transitions, uncertainty in engaging support and help, pandemic-motivated care planning, maintaining the wellbeing of the person living with dementia, and trust, loss of agency and confusion. CONCLUSIONS: Family carers may be reluctant to seek support because of fear of what may happen to their relative, which may include hospitalisation and becoming ill with COVID-19, care home placement, or not being able to be with a relative at the end of life. In some cases, a lack of trust has developed, and instead carers are seeking support from alternative services they trust such as nationally known charities.This study was used to inform the development of a decision aid to support family carers making decisions about care for their relative with dementia during the pandemic, who the lack the capacity to make their own decisions.

Enteral tube feeding for people with severe dementia.

BACKGROUND: The balance of benefits and harms associated with enteral tube feeding for people with severe dementia is not clear. An increasing number of guidelines highlight the lack of evidenced benefit and potential risks of enteral tube feeding. In some areas of the world, the use of enteral tube feeding is decreasing, and in other areas it is increasing. OBJECTIVES: To assess the effectiveness and safety of enteral tube feeding for people with severe dementia who develop problems with eating and swallowing or who have reduced food and fluid intake. SEARCH METHODS: We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, four other databases and two trials registers on 14 April 2021. SELECTION CRITERIA: We included randomised controlled trials (RCTs), or controlled non-randomised studies. Our population of interest was adults of any age with a diagnosis of primary degenerative dementia of any cause, with severe cognitive and functional impairment, and poor nutritional intake. Eligible studies evaluated the effectiveness and complications of enteral tube feeding via a nasogastric or gastrostomy tube, or via jejunal post-pyloric feeding, in comparison with standard care or enhanced standard care, such as an intervention to promote oral intake. Our primary outcomes were survival time, quality of life, and pressure ulcers. DATA COLLECTION AND ANALYSIS: Three review authors screened citations and two review authors assessed full texts of potentially eligible studies against inclusion criteria. One review author extracted data, which were then checked independently by a second review author. We used the 'Risk Of Bias In Non-randomised Studies of Interventions' (ROBINS-I) tool to assess the risk of bias in the included studies. Risk of confounding was assessed against a pre-agreed list of key potential confounding variables. Our primary outcomes were survival time, quality of life, and pressure ulcers. Results were not suitable for meta-analysis, so we presented them narratively. We presented results separately for studies of percutaneous endoscopic gastrostomy (PEG) feeding, nasogastric tube feeding and studies using mixed or unspecified enteral tube feeding methods. We used GRADE methods to assess the overall certainty of the evidence related to each outcome for each study. MAIN RESULTS: We found no eligible RCTs. We included fourteen controlled, non-randomised studies. All the included studies compared outcomes between groups of people who had been assigned to enteral tube feeding or oral feeding by prior decision of a healthcare professional. Some studies controlled for a range of confounding factors, but there were high or very high risks of bias due to confounding in all studies, and high or critical risks of selection bias in some studies. Four studies with 36,816 participants assessed the effect of PEG feeding on survival time. None found any evidence of effects on survival time (low-certainty evidence). Three of four studies using mixed or unspecified enteral tube feeding methods in 310 participants (227 enteral tube feeding, 83 no enteral tube feeding) found them to be associated with longer survival time. The fourth study (1386 participants: 135 enteral tube feeding, 1251 no enteral tube feeding) found no evidence of an effect. The certainty of this body of evidence is very low. One study of PEG feeding (4421 participants: 1585 PEG, 2836 no enteral tube feeding) found PEG feeding increased the risk of pressure ulcers (moderate-certainty evidence). Two of three studies reported an increase in the number of pressure ulcers in those receiving mixed or unspecified enteral tube feeding (234 participants: 88 enteral tube feeding, 146 no enteral tube feeding). The third study found no effect (very-low certainty evidence).  Two studies of nasogastric tube feeding did not report data on survival time or pressure ulcers. None of the included studies assessed quality of life. Only one study, using mixed methods of enteral tube feeding, reported on pain and comfort, finding no difference between groups. In the same study, a higher proportion of carers reported very heavy burden in the enteral tube feeding group compared to no enteral tube feeding. Two studies assessed the effect of nasogastric tube feeding on mortality (236 participants: 144 nasogastric group, 92 no enteral tube feeding). One study of 67 participants (14 nasogastric, 53 no enteral tube feeding) found nasogastric feeding was associated with increased mortality risk. The second study found no difference in mortality between groups. The certainty of this evidence is very low. Results on mortality for those using PEG or mixed methods of enteral tube feeding were mixed and the certainty of evidence was very low. There was some evidence from two studies for enteral tube feeding improving nutritional parameters, but this was very low-certainty evidence. Five studies reported a variety of harm-related outcomes with inconsistent results. The balance of evidence suggested increased risk of pneumonia with enteral tube feeding. None of the included studies assessed behavioural and psychological symptoms of dementia. AUTHORS' CONCLUSIONS: We found no evidence that tube feeding improves survival; improves quality of life; reduces pain; reduces mortality; decreases behavioural and psychological symptoms of dementia; leads to better nourishment; improves family or carer outcomes such as depression, anxiety, carer burden, or satisfaction with care; and no indication of harm. We found some evidence that there is a clinically significant risk of pressure ulcers from enteral tube feeding. Future research should focus on better reporting and matching of control and intervention groups, and clearly defined interventions, measuring all the outcomes referred to here.
