Efficacy and ethics of artificial nutrition in patients with neurologic impairments in home care

Relationship between Aspiration Pneumonia and Feeding Care among Home Care Patients with an In-Dwelling Nasogastric Tube in Taiwan: A Preliminary Study

Home care patients have swallowing dysfunction and rely on an in-dwelling nasogastric tube (NGT) to complement oral food intake, supplement their diet, and maintain adequate nutritional status. This study explored the relationship between aspiration pneumonia (AP) and feeding care among home care patients with an in-dwelling NGT. This preliminary study employed a cross-sectional design. There were 35 patients who relied on an in-dwelling NGT to complement their oral intake of food (NGT-oral feeding) and their primary caregivers participated in this study. All of them developed AP in the past year. Factors involving food intake performance during mealtime of the home care patients and feeding care provided by the caregivers were simultaneously observed and recorded. Among the six risk factors univariately correlated with the incidence of AP, feeding in a noisy environment, using a large spoon to feed the participants, more than 5 mL of food per mouthful, food intake duration lasting > 30 min, swallowing twice for each mouthful of food, and coughing at least once every day remained significant in the logistic regression model (all p < 0.05). Four risk factors for AP were correlated with feeding care; the adjusted risk ratio ranged from 6.17 to 14.96 (all p < 0.05). In addition to each individual’s food intake ability, improper feeding assistance was related to the risk factors for AP among home care patients with NGT-oral feeding. Thus, home caregivers should receive safe oral feeding education and training.

Race and prevalence of percutaneous endoscopic gastrostomy tubes in patients with advanced dementia

OBJECTIVE

Millions of Americans may face hard decisions when it comes to providing nutrition for their loved ones with advanced dementia. This study aimed to ascertain whether there is a difference in feeding tube placement between White and Black patients with advanced dementia and whether this potential difference varied by patient's other demographic and clinical characteristics.

METHOD

This is a retrospective, observational study conducted at Novant Health, a 15-hospital system in the southeastern United States. Data were obtained from Epic systems and included all hospital admissions with a diagnosis of advanced dementia, a total of 21,939, between July 1, 2015, and December 31, 2018. Descriptive statistics and logistics analyses were conducted to assess the relationship between receiving percutaneous endoscopic gastrostomy (PEG) and race, controlling for demographic and clinical characteristics.

RESULTS

Among patients admitted with advanced dementia, the multivariable logistic regression, controlled for age, gender, LOS, palliative care, and vascular etiology showed that Blacks had higher odds of having PEG tubes inserted than White patients (OR 1.97; CI 1.51-2.55; P < 0.001). Patients with longer stays had higher odds of PEG tube insertion. Females had lower odds of PEG tube insertion than males. There was no statistical significance in PEG insertion based on age, etiology, and palliative care consult.

SIGNIFICANCE OF RESULTS

The reasons for the observed higher odds of receiving PEG tubes among Black patients than White patients are likely multifactorial and embedded in a different approach to end-of-life care conversations by providers and caregivers of Black and White patients. Providers may need to be more aware of potential unconscious biases when talking to caregivers, especially in race-discordant relationships, have courageous conversations with caregivers, and be more aware of the importance of keeping in mind families' and caregivers' culture, including spirituality, when making end-of-life 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.

The Efficacy and Safety of Tube Feeding in Advanced Dementia Patients: A Systemic Review and Meta-Analysis Study

OBJECTIVES

The current study aimed to conduct a systematic review and meta-analysis to explore the efficacy and safety of tube feeding in patients with advanced dementia.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

PubMed, Medline, Embase, and Cochrane Library were searched from inception until March 7, 2020, to obtain relevant studies.

INTERVENTION

Feeding with nasogastric tube or percutaneous endoscopic gastrostomy (PEG).

MEASURES

We evaluated the associations of tube feeding and the risk of mortality, period of survival days, tube-related complications, and nutritional status. Data from original studies were synthesized by using a random-effects model. Each selected article was assessed for bias using the Newcastle-Ottawa Scale. A narrative synthesis and pooled analyses are reported.

RESULTS

Twelve trials were eligible, involving 1805 patients with tube feeding (mean age: 82.8 years; 71.3% female) and 3861 without tube feeding (mean age: 82.7; 68.7% female). For mortality rate, patients with advanced dementia with tube feeding are associated with significantly higher mortality rate [k = 8; odds ratio (OR) 1.79; 95% confidence interval (CI) 1.04-3.07; P = .03]. Initially, no association was found for the risk of pneumonia and pressure sore between groups. However, sensitivity analysis showed patients with advanced dementia with PEG tube feeding have significantly higher risk of pneumonia (OR 3.56; 95% CI 2.32-5.44; P < .001) and pressure sore (OR 2.25; 95% CI 1.92-2.63; P < .001). Finally, no association was found for the survival period and nutritional status between groups.

CONCLUSIONS AND IMPLICATIONS

This meta-analysis indicates that tube feeding is associated with increased mortality rate and possible tube-related complications, but not improves with prolonging survival days and nutritional status. Shared decision-making routinely before insertion of a tube between caregivers and physicians is recommended.

Mortality and Institutionalization After Percutaneous Endoscopic Gastrostomy in Parkinson's Disease and Related Conditions

Background

Percutaneous endoscopic gastrostomy (PEG) can facilitate feeding and medication administration in dysphagic patients with Parkinson's disease and related disorders. Information on survival, institutionalization, and complications post PEG might inform feeding decisions.

Method

A total of 93 patients with Parkinson's disease and related disorders were identified by review of PEG registers and by searching the administrative databases in 2 large UK university hospitals (2005-2017); 83 case notes were available for retrospective review. Care processes and outcomes were assessed.

Results

The following were the diagnoses: 58 (70%) had Parkinson's disease, 10 (12%) had progressive supranuclear palsy, 5 (6%) had multiple system atrophy, 3 (4%) had dementia with Lewy bodies, and 7 (8%) had vascular parkinsonism. The median age was 78 years (interquartile range 72-82); 29 (35%) were women. Care processes included a future care plan in place prior to admission for 18 patients (22%), and PEG was placed during emergency admission in 68 patients (82%). The outcomes included median survival at 422 days; 30-day mortality rate was 6% (5 patients); and of 56 patients admitted from home, 18 (32%) were discharged to institutions (nursing or care homes). The most common complication was aspiration pneumonia for 18 (22%) of patients. Age, sex, diagnosis, admission type, comorbidities, and place of residence did not predict survival. Discharge to own home and follow-up by the home enteral feeding team were associated with longer survival.

Conclusion

We recommend markers of advanced disease should prompt advanced care planning. Discussions about PEG feeding should include information about post-PEG survival, complications, and risk of institutionalization. Further research is needed on quality-of-life post PEG and ways to reduce aspiration pneumonia. All PEG patients should have nutrition team follow-up.

Nasogastric tube feeding versus assisted hand feeding in-home healthcare older adults with severe dementia in Taiwan: a prognosis comparison

BACKGROUND

All individuals with severe dementia should be offered careful hand feeding. However, under certain circumstances, people with severe dementia have a feeding tube placed. In Taiwan, tube feeding rate in demented older home care residents is increasing; however, the benefits of tube feeding in this population remain unknown. We compared the clinical prognosis and mortality of older patients with severe dementia receiving nasogastric tube feeding (NGF) or assisted hand feeding (AHF).

METHODS

Data from the in-home healthcare system between January 1 and December 31, 2017 were analyzed to identify 169 participants over 60 years of age in this retrospective longitudinal study. All subjects with severe dementia and complete functional dependence suffered from difficulty in oral intake and required either AHF or NGF. Data were collected from both groups to analyze pneumonia, hospitalization, and mortality rates.

RESULTS

A total of 169 subjects (56 males and 113 females, aged 85.9 ± 7.5 years) were analyzed. 39 required AHF and 130 NGF. All subjects were bedridden; 129 (76%) showed Barthel index < 10. Pneumonia risk was higher in the NGF group (48%) than in the AHF group (26%, p = 0.015). After adjusting for multiple factors in the regression model, the risk of pneumonia was not significantly higher in the NGF group compared with the AHF group. One-year mortality rates in the AHF and NGF groups were 8 and 15%, respectively, and no significant difference was observed after adjustment with logistic regression (aOR = 2.38; 95% CI, 0.58-9.70). There were no significant differences in hospitalization rate and duration.

CONCLUSIONS

For older patients with dementia requiring in-home healthcare, NGF is not associated with a significantly lower risk of pneumonia than AHF. Additionally, neither mortality nor hospitalization rates decreased with NGF. On the contrary, a nonsignificant trend of increased risk of pneumonia was observed in NGF group. Therefore, the benefits of NGF are debatable in older patients with severe dementia requiring in-home healthcare. Continued careful hand feeding could be an alternative to NG feeding in patients with severe dementia. Furthermore, large-scale studies on in-home healthcare would be required to support these results.

Tube Feeding in Individuals with Advanced Dementia: A Review of Its Burdens and Perceived Benefits

Background

Dementia remains a growing concern for societies globally, particularly as people now live longer. About 90% of individuals with advanced dementia suffer from eating problems that lead to general health decline and ultimately impacts upon the physical, psychological, and economic wellbeing of the individuals, caregivers, and the wider society.

Objective

To evaluate the burdens and perceived benefits of tube feeding in individuals with advanced dementia.

Design

Narrative review.

Methods

Computerized databases, including PubMed, Embase, Medline, CINAHL, PsycInfo, and Google Scholar were searched from 2000 to 2019 to identify research papers, originally written in or translated into English language, which investigated oral versus tube feeding outcome in individuals with advanced dementia.

Results

Over 400 articles were retrieved. After quality assessment and careful review of the identified articles, only those that met the inclusion criteria were included for review.

Conclusion

Tube feeding neither stops dementia disease progression nor prevents imminent death. Each decision for feeding tube placement in individuals with advanced dementia should be made on a case-by-case basis and involve a multidisciplinary team comprising experienced physicians, nurses, family surrogates, and the relevant allied health professionals. Careful considerations of the benefit-harm ratio should be discussed and checked with surrogate families if they would be consistent with the wishes of the demented person. Further research is required to establish whether tube feeding of individuals with advanced dementia provides more burdens than benefits or vice-versa and evaluate the impacts on quality of life and survival.

Participation of nurses and care workers in the decision-making process for people with dementia in Japan: Discussion paper

Numerous socio-legal factors make the process of surrogate decision-making for people living in dementia very complicated in Japan. In this discussion paper, we argue that the lack of early consultation between patients, surrogate decision-makers and healthcare providers and the overreliance of patients and their families on doctors to assume the decision-making role lead to healthcare practices that may not align with the patient's wishes. Further, we argue that lack of laws on surrogate decision-making, changing family structure and the liabilities associated with the care of people living with dementia contribute to the complexity of the decision-making process in Japan. Finally, given the rapidly changing social and healthcare norms in Japan, we call for greater involvement of nurses and care workers in the decision-making process to ensure patient-centric treatment and care are adopted.

Self-Feeding Ability as a Predictor of Mortality Japanese Nursing Home Residents: A Two-Year Longitudinal Study

OBJECTIVES

To examine the ability of different elements of the Self-Feeding Assessment Tool for Elderly with Dementia (SFED) to predict mortality risk in nursing home residents.

DESIGN AND SETTING

Data from 387 residents in five nursing homes for the elderly in Japan were obtained using a baseline survey. This measure's ability to predict mortality risk was examined over a two-year observation period. Participants and Measurement: Demographic information (sex, age, height, weight, medical history) on 387 initial participants was gathered. A total of 10 individuals were excluded from the analysis because of the inability to eat by mouth at baseline, while 36 were excluded owing to missing mortality data during the observation period. The resulting 341 residents were divided into a death group or survival group according to whether they were still alive after two-year observation period. In addition to basic information and the SFED, the baseline survey included the Barthel Index (BI), Clinical Dementia Rating (CDR), and Mini Nutritional Assessment-Short Form (MNA®-SF). The ability of SFED to predict time-to-event mortality was examined using Cox proportional hazards regression analysis, including other measures associated with mortality as confounding variables.

RESULTS

In total, 129 participants (37.8%) died during the observation period, and their mean SFED score was significantly lower than that of surviving ones (11.1 ± 6.7 vs. 15.0 ± 5.6, P<0.001). SFED score was significantly associated with two-year mortality in the Cox proportional hazards regression analysis after adjusting for sex, age, medical history, BI, CDR, and MNA®-SF (hazard ratio = 0.941, 95% confidence interval = 0.898-0.985, P = 0.010). Additionally, three SFED categories were significantly associated with mortality risk: movement ("able to eat without dropping food"), concentration ("able to maintain attention to meal"), and safety ("able to swallow without choking, with no change in vocal quality after eating").

CONCLUSIONS

Self-feeding ability as measured by SFED score was associated with long-term mortality in elderly living in nursing homes. Accordingly, adjusting feeding assistance based on regular SFED-based assessments may help maintain self-feeding ability and enhance quality of life in this population, as well as providing evidence for end-of-life care options and greatly improving care quality.

Effects of oral ingestion on physical functions before tube feeding in adults with severe motor and intellectual disabilities

This study aimed to determine the significance of oral ingestion in tube-fed adults. Six males and three females (mean age 48.1 ± 12.4 years) with severe motor and intellectual disabilities were included in this study. The subjects were monitored for cerebral blood flow (CBF) by functional near-infrared spectroscopy imaging, gastric motor function by electrogastrography, and arterial oxygen saturation (SpO₂) and pulse rate with a biological data monitoring device. The subjects were divided into two groups, settings A and B. In setting A, after resting for 30 min, the subjects were tube fed a routinely used enteral nutrient solution. In Setting B, the subjects received 10 cc of thickened enteral nutrient solution prior to tube feeding. Cerebral function as measured by CBF significantly increased after tube feeding under setting A (without oral ingestion), as compared to the resting state. Under setting B (with oral ingestion), CBF significantly increased after oral ingestion and after tube feeding. SpO₂ significantly decreased under setting B after oral ingestion and after tube feeding. Gastric motor function showed no significant change after tube feeding in either setting. The pulse rate significantly increased before tube feeding as compared to that in the resting state, after feeding as compared to before feeding and after feeding as compared to the resting state. Our data suggest that introducing oral ingestion, at least partially, in tube-fed individuals with severe dysphagia is beneficial in that it can stimulate cerebral function.

The outcomes of long term home enteral nutrition (HEN) in older patients with severe dementia

BACKGROUND AND AIMS

European and international guidelines advice against initiating tube-feeding in patients with severe dementia. These recommendations are based on studies with important methodological limitations that evaluated the benefits of artificial nutrition in patients with percutaneous endoscopic gastrostomy almost exclusively in terms of the prolongation of survival. The aims of this study were to assess the harmful effects of home enteral nutrition administered via the nasogastric tube and percutaneous endoscopic gastrostomy in patients with advanced dementia in terms of mechanical, gastrointestinal and metabolic complications, to estimate the survival, to explore the risk factors for mortality and to compare the outcomes of patients with advanced dementia with those of patients without dementia.

METHODS

The retrospective observational study was carried out on 585 consecutive patients of the mean age of 85.6 ± 6.9 years. They were treated using home enteral nutrition from 2010 to 2015 according to follow-up protocols adopted by the Clinical Nutrition Unit of an Italian geriatric research hospital (IRCCS-INRCA, Ancona). Incidence rates of mechanical, gastrointestinal and metabolic complications and survival rates in patients with severe dementia were compared to those in patients without dementia. The Cox proportional hazards model was used to evaluate the mortality risk factors.

RESULTS

There was no difference between the incidence rates of complications in patients with severe dementia and those in patients without dementia. The incidence of mechanical complications was 1.35/1000 days for patients without dementia vs. 1.53/1000 days for patients with dementia (p = 0.270), the incidence of gastrointestinal complications was 1.30/1000 days for patients without dementia vs. 1.35/1000 days for patients with dementia (p = 0.984) and the incidence of metabolic complications was 0.36/1000 days for patients without dementia vs. 0.35/1000 days for patients with dementia (p = 0.252). The Kaplan Mailer analyses showed that there was no evidence to support the theses on poorer prognosis of survival of patients with dementia (median survival was 193 days for patients without dementia vs. 192 days for patients with dementia, (p > 0.05)). The female gender, advanced age, nasogastric tube, diabetes mellitus and chronic renal failure were identified as risk factors. Subjects whose Geriatric Nutritional Risk Index values were higher had a lower risk of mortality.

CONCLUSIONS

The discussion on the appropriateness of enteral nutrition in patients with severe dementia is still open. Our results show that, if there is a medical prescription for tube-feeding and a patient's surrogate decision-makers express free and informed consent to the tube-feeding of the patient, enteral nutrition should not be contraindicated a priori if the patient has severe dementia. Regular follow-up is mandatory to guarantee adherence to the therapy and achieve its initial aims and to ensure that the principles of beneficence and nonmaleficence are respected.

Survival times with and without tube feeding in patients with dementia or psychiatric diseases in Japan

BACKGROUND

It is widely supposed that there has been no evidence of increased survival in patients with advanced dementia receiving enteral tube feeding. However, more than a few studies have reported no harmful outcome from tube feeding in dementia patients compared to in patients without dementia.

METHODS

This was a retrospective study. Nine psychiatric hospitals in Okayama Prefecture participated in this survey. All inpatients fulfilling the entry criteria were evaluated. All subjects suffered from difficulty with oral intake. Attending physicians thought that the patients could not live without long-term artificial nutrition. The physicians decided whether to make use of long-term artificial nutrition between January 2012 and December 2014.

RESULTS

We evaluated 185 patients. Their mean age was 76.6 ± 11.4 years. Of all subjects, patients with probable Alzheimer's disease (n = 78) formed the biggest group, schizophrenia patients (n = 44) the second, and those with vascular dementia (n = 30) the third. The median survival times were 711 days for patients with tube feeding and 61 days for patients without tube feeding. In a comparison different types of tube feeding, median survival times were 611 days for patients with a nasogastric tube and more than 1000 days for those with a percutaneous endoscopic gastrostomy tube.

CONCLUSION

Patients with tube feeding survived longer than those without tube feeding, even among dementia patients. This study suggests that enteral nutrition for patients with dementia prolongs survival. Additionally, percutaneous endoscopic gastrostomy tube feeding may be safer than nasogastric tube feeding among patients in psychiatric hospitals.

Tube Feeding among Elder in Long-Term Care Facilities: A Systematic Review and Meta-Analysis

OBJECTIVE

The use of tube feeding for elderly patients with poor nutritional intake is a ubiquitous method of feeding. This systematic review and meta-analysis were carried out to compare nutritional benefits of enteral feeding versus oral feeding in long-term care facilities.

SETTING

Databases including the Cochrane Library, ProQuest, PubMed, EMBASE, EBSCO, Web of Science and Google Scholar through April 2014 using keywords including enteral feeding, tube feeding or oral feeding combined with long term care facilities or nursing home.

PARTICIPANTS

Eight articles, with 841 participants were included in meta-analysis and 13 articles were included in systematic review. The elderly had to live in long-term care institutions and could not be on any mechanically assisted ventilation systems or be in any type of post-operative status.

MEASUREMENTS

The three investigators extracted and appraised data using the same study design, baseline characteristics, and outcomes, independently.

RESULTS

Following a systematic review, 13 articles out of 8218 original research articles were selected for this analysis. Meta-analysis of tube-fed patients found lower levels of hemoglobin (Weighted Mean Difference (WMD -0.21g/dl; 95% CI -0.42 to -0.01; p=0.04) and creatinine (WMD -0.08g/dl; 95% CI -0.17 to 0.00, p=0.05). Moreover, the results showed that there were no benefits regarding body mass index (BMI), albumin, dietary intake of proteins, total calories and fat.

CONCLUSIONS

The results show that tube feeding does not increase patients' nutrients absorption to improve nutritional status. Instead, these results indicate that oral feeding is better regarding some nutritional biochemical parameters.

Is tube feeding futile in advanced dementia?

It is controversial whether tube feeding in people with dementia improves nutritional status or prolongs survival. Guidelines published by several professional societies cite observational studies that have shown no benefit and conclude that tube feeding in patients with advanced dementia should be avoided. However, all studies on tube feeding in dementia have major methodological flaws that invalidate their findings. The present evidence is not sufficient to justify general guidelines. Patients with advanced dementia represent a very heterogeneous group, and evidence demonstrates that some patients with dementia benefit from tube feeding. However, presently available guidelines make a single recommendation against tube feeding for all patients. Clinicians, patients, and surrogates should be aware that the guidelines and prior commentary on this topic tend both to overestimate the strength of evidence for futility and to exaggerate the burdens of tube feeding. Shared decision making requires accurate information tailored to the individual patient's particular situation, not blanket guidelines based on flawed data. Lay Summary: Many doctors believe that tube feeding does not help people with advanced dementia. Scientific studies suggest that people with dementia who have feeding tubes do not live longer or gain weight compared with those who are carefully hand fed. However, these studies are not very helpful because of flaws in design, which are discussed in this article. Guidelines from professional societies make a blanket recommendation against feeding tubes for anyone with dementia, but an individual approach that takes each person's situation into account seems more appropriate. Patients and surrogates should be aware that the guidelines on this topic tend both to underestimate the benefit and exaggerate the burdens of tube feeding.

A Matter of Taste? Quality of Life in Day-to-Day Living with ALS and a Feeding Tube

Although people often refer to quality of life and there is a respectable research tradition to establish it, the meaning of the term is unclear. In this article we qualitatively study an intervention of which the quantitative effects are documented as indecisive. We do this in order to learn more about what the meaning of the term quality of life means when it is studied in daily life. With the help of these findings we reflect on the intricacies of objectifying and measuring quality of life using quantitative research designs. Our case is the feeding tube for patients suffering from ALS, a severe motor neuron disease that rapidly and progressively incapacitates patients. We studied how these patients, who lived in the Netherlands, anticipated and lived with a feeding tube in the course of their physical deterioration. Our analysis shows that the quality of life related to the feeding tube has to be understood as a process rather than as an outcome. The feeding tube becomes a different thing as patients move through the various phases of their illness, due to changes in their condition, living circumstances, and concerns and values. There are very different appreciations of the way the feeding tube changes the body's appearance and feel. Some patients refuse it because they feel it disfigures their body, whereas others are indifferent to its appearance. Our conclusion is that these differences are difficult to grasp with a quantitative study designs because 'matters of taste' and values are not distributed in a population in the same ways as physiological responses to medication. Effect studies assume physiological responses to be more or less the same for everyone, with only gradual differences. Our analysis of quality in daily life, however, shows that what a treatment comes to be and how it is valued shows shows generalities for subgroups rather than populations.

Outcomes of enteral nutrition for patients with advanced dementia: a systematic review

The present article aims to evaluate the outcomes of enteral nutrition for people with advanced dementia. A systematic review was conducted by searching The Cochrane Library, MEDLINE, EMBASE, PROQUEST and LILACS for articles that were published from 2008 to 2013. Prospective and retrospective studies involving a control group were searched. Data were independently extracted and assessed by one reviewer and checked by a second. Searched outcomes included survival, clinical and nutritional parameters and complications. In total, nine controlled studies were identified from several parts of the world: Israel, Italy, Japan, the United States and Brazil. Most of the studies did not report any outcome of harm with enteral nutrition use in dementia patients compared with patients without dementia. A study with a higher follow-up period demonstrated improvements in albumin, weight and chronic inflammation parameters. It is not possible to affirm that tube feeding is harmful for dementia patients. Thus, an adequate follow-up by a multidisciplinary team may lower complications associated with this therapy and thus improve survival.
