Appropriate use of artificial nutrition and hydration--fundamental principles and recommendations

Ethical Issues and the Role of Palliative Care for Patients with Aspiration Pneumonia

Aspiration pneumonia is a clinical entity with important ethical considerations. It is imperative for clinicians to understand these considerations to best provide counsel to patients and their families, allowing them to make fully informed decisions. Given that aspiration pneumonia is frequently associated with end of life, there are palliative medicine principles that may help in the treatment of this disease.

End-of-Life Decision Making in Patients with Advanced Dementia: The Perspectives of the Korean General Population and Clinicians

OBJECTIVE

Korea's transition into a super-aged society brings to the forefront the escalating dementia prevalence and the consequent rise in mortality, highlighting the need for effective end-of-life (EOL) care strategies. Despite legislative advancements, gaps remain in addressing the medical and ethical challenges of EOL care for patients with advanced dementia, particularly in evaluating treatment options like nasogastric tube (NGT) use and mechanical ventilation (MV). This study investigates the attitudes of the general population (GP) and clinicians in Korea towards EOL treatment decisions.

METHODS

A cross-sectional, web-based survey was conducted among 500 members of the GP and 200 clinicians from a university hospital. Case vignettes were used to assess attitudes towards EOL treatment decisions, specifically focusing on NGT and MV use, and to explore the influencing factors.

RESULTS

There was a notable difference in favorable attitudes toward NGT withdrawal between the GP (62.2%) and clinicians (39.0%). Otherwise, both groups showed higher acceptance of MV withholding (82.2% [GPs] and 82.5% [clinicians]) when informed of the patient's verbal intention regarding life-sustaining treatment (LST), and attitudes were more positive with written advance directives. Also, it was decreased when patient intentions were unclear.

CONCLUSION

The results suggested the need to consider NGT as a medical intervention requiring a risk-benefit analysis. Although LST decision-making in patients with advanced dementia is still limited in Korea, this study showed the shared recognition among the GP and clinicians of the importance of EOL treatment decisions that consider patient wishes and quality of life for patients with advanced dementia.

ESPEN guideline on nutrition and hydration in dementia - Update 2024

BACKGROUND & AIMS

Dementia is accompanied by a variety of changes that result in an increased risk of malnutrition and low-intake dehydration. This guideline update aims to give evidence-based recommendations for nutritional care of persons with dementia in order to prevent and treat these syndromes.

METHODS

The previous guideline version was reviewed and expanded in accordance with the standard operating procedure for ESPEN guidelines. Based on a systematic search in three databases, strength of evidence of appropriate literature was graded by use of the SIGN system. The original recommendations were reviewed and reformulated, and new recommendations were added, which all then underwent a consensus process.

RESULTS

40 recommendations for nutritional care of older persons with dementia were developed and agreed, seven at institutional level and 33 at individual level. As a prerequisite for good nutritional care, organizations caring for persons with dementia are recommended to employ sufficient qualified staff and offer attractive food and drinks with choice in a functional and appealing environment. Nutritional care should be based on a written care concept with standardized operating procedures. At the individual level, routine screening for malnutrition and dehydration, nutritional assessment and close monitoring are unquestionable. Oral nutrition may be supported by eliminating potential causes of malnutrition and dehydration, and adequate social and nursing support (including assistance, utensils, training and oral care). Oral nutritional supplements are recommended to improve nutritional status but not to correct cognitive impairment or prevent cognitive decline. Routine use of dementia-specific ONS, ketogenic diet, omega-3 fatty acid supplementation and appetite stimulating agents is not recommended. Enteral and parenteral nutrition and hydration are temporary options in patients with mild or moderate dementia, but not in severe dementia or in the terminal phase of life. In all stages of the disease, supporting food and drink intake and maintaining or improving nutrition and hydration status requires an individualized, comprehensive approach. Due to a lack of appropriate studies, most recommendations are good practice points.

CONCLUSION

Nutritional care should be an integral part of dementia management. Numerous interventions are available that should be implemented in daily practice. Future high-quality studies are needed to clarify the evidence.

Comparison of the Life-Sustaining Treatment, Cardiopulmonary Resuscitation, and Palliative Care Implementation Rates between Homebound Patients with Malignant and Nonmalignant Disease Who Died in an Acute Hospital Setting: A Single-Center Retrospective Study

OBJECTIVE

This study investigated and compared the implementation of life-support treatment (LST), cardiopulmonary resuscitation (CPR) implementation rates, and the influence of acute illnesses on the introduction of palliative care (PC) to homebound patients with malignant and nonmalignant disease, who subsequently died in an acute hospital setting.

METHODS

Among the homebound patients admitted to the ward in our hospital from 2011 to 2018, we investigated and compared the attributes, underlying diseases, causes of death, and rates of implementation of LST, CPR, and PC between patients with malignant and nonmalignant disease who died in the ward, using data obtained from hospitalization records. Furthermore, acute illnesses related to the introduction of PC were examined.

RESULTS

Of the 551 homebound patients admitted to the ward of an acute hospital, 119 died in the ward. Of the deceased patients, 60 had malignant disease and 59 had nonmalignant disease. Patients with nonmalignant disease had higher rates of LST implementation and CPR and a lower rate of PC. Patients with infectious disease, who required antimicrobial drugs, had significantly lower PC introduction rates.

CONCLUSION

Understanding the influence of the timing of PC introduction in acute care for homebound patients with advanced chronic illness are issues to be considered.

Nutrition strategies for pressure injury management: Implementing the 2019 International Clinical Practice Guideline

Nutrition is an important component in the prevention and treatment of pressure injuries (PIs). The skin is the largest organ of the body, and macronutrients and micronutrients in specific amounts are required to maintain and repair body tissues. The European Pressure Ulcer Advisory Panel, the National Pressure Injury Advisory Panel, and the Pan Pacific Pressure Injury Alliance Prevention and Treatment of Pressure Ulcers/Injuries: 2019 Clinical Practice Guideline includes nutrition recommendations for PI management. This manuscript identifies the key nutrients required for wound healing, reviews the evidence in the 2019 nutrition recommendations, and translates the recommendations provided into key points to be incorporated into policy and practice that impact patient outcomes.

Artificial Nutrition in Patients with Advanced Malignancy

Cancer is a progressive disease that can lead to malnutrition and cachexia. Artificial nutrition is a medical therapy used to combat malnutrition in these patients. In this article, the authors discuss factors affecting the decision to use artificial nutrition, including the patient's mental and physical health, technical factors of the procedures used to deliver artificial nutrition, and the oncologic factors affecting treatment. Through this review, the authors provide guidelines on who is and is not likely to benefit from therapy, available routes of administration, and necessary factors to consider for appropriate decision-making for palliative patients and those with advanced cancers."

Ethical considerations at the end-of-life care

The goal of end-of-life care for dying patients is to prevent or relieve suffering as much as possible while respecting the patients’ desires. However, physicians face many ethical challenges in end-of-life care. Since the decisions to be made may concern patients’ family members and society as well as the patients, it is important to protect the rights, dignity, and vigor of all parties involved in the clinical ethical decision-making process. Understanding the principles underlying biomedical ethics is important for physicians to solve the problems they face in end-of-life care. The main situations that create ethical difficulties for healthcare professionals are the decisions regarding resuscitation, mechanical ventilation, artificial nutrition and hydration, terminal sedation, withholding and withdrawing treatments, euthanasia, and physician-assisted suicide. Five ethical principles guide healthcare professionals in the management of these situations.

Views of Registered Dietitians Compared to Speech-Language Pathologists on Artificial Nutrition and Hydration at the End of Life

OBJECTIVE

To analyze and compare the knowledge and opinions of registered dietitian nutritionists (RDNs) about artificial nutrition and hydration (ANH) in a terminal illness. Beliefs of speech-language pathologists (SLPs) were also considered and compared against RDN data.

METHODS

This is a descriptive analysis utilizing survey responses from RDNs and SLPs regarding ANH in a case study patient with advanced dementia.

RESULTS

There was a strong belief among RDNs that ANH at end of life (EOL) would improve nutritional status, although a correlation was found between those in favor of ANH and believing it was ethical to withhold ANH at EOL (R² = 0.109, p = 0.002). Responses indicated that SLPs need more education regarding ANH techniques, while RDNs felt ANH would improve aspiration risk. Place of employment, religion and age of respondents were also found to impact beliefs.

CONCLUSION

Clinicians, specifically RDNs, working with patients at EOL need more evidenced-based education on the risks and benefits of ANH. Decisions regarding care of patients at EOL should be void of clinicians' personal bias which may affect ethical treatment in the clinical setting. Further controlled trials must be performed before claims can be made regarding ANH at EOL.

Long-term prognosis of enteral feeding and parenteral nutrition in a population aged 75 years and older: a population-based cohort study

Background

Enteral feeding and parenteral nutrition (PN) using gastrostomy (GS) and a nasogastric tube feeding (NGT) and PN should be initiated for older patients based on their prognoses. This study aimed to investigate the long-term prognosis of patients aged ≥75 years who underwent enteral feeding via GS and NGT as well as PN.

Methods

A population-based cohort study was conducted using Japan’s universal health insurance claims in the Nara Prefecture. This study enrolled 3,548 patients aged ≥75 years who received GS (N=770), NGT (N=2,370), and PN (N=408) during hospital admissions between April 2014 and March 2016. The GS group was further categorized into secondary GS (N=400) with preceding NGT or PN within 365 days and primary GS (N=370) without preceding NGT or PN groups. In the secondary GS group, 356 (96%) patients received NGT (versus PN). The outcome was mortality within 730 days after receiving GS, NGT, and PN. Cox regression analyses in cases with or without malignant diseases, adjusted for sex, age, comorbidity, and hospital type, were performed to compare mortality in the groups.

Results

Of the 3,548 participants, 2,384 (67%) died within 730 days after the initiation of GS and NGT and PN. The 2-year mortality rates in the secondary GS, primary GS, NGT, and PN groups were 58%, 66%, 68%, and 83% in patients without malignancies and 67%, 71%, 74%, and 87% in those with malignancies, respectively. In the non-malignant group, Cox regression analysis revealed that secondary GS (hazard ratio (HR) = 0.43, 95% CI: 0.34–0.54), primary GS (HR = 0.51, 95% CI: 0.40–0.64), and NGT (HR = 0.71, 95% CI: 0.58-0.87) were statistically significantly associated with lower mortality compared with PN.

Conclusions

Approximately 58% to 87% patients aged ≥75 years died within 730 days after initiation of nutrition through GS, NGT, or PN. Patients with non-malignant diseases who received secondary GS exhibited better 2-year prognosis than those who received NGT or PN. Healthcare professionals should be aware of the effectiveness and limitations of enteral feeding and PN when considering their initiation.

Strengths of the French end-of-life Law as Well as its Shortcomings in Handling Intractable Disputes Between Physicians and Families

French end-of-life law aims at protecting patients from unreasonable treatments, but has been used to force caregivers to prolong treatments deemed unreasonable. We describe six cases (five intensive care unit patients including two children) where families disagreed with a decision to withdraw treatments and sued medical teams. An emergent inquiry was instigated by the families. In two cases, the court rejected the families' inquiries. In two cases, the families appealed the decision, and in both the first jurisdiction decision was confirmed, compelling caregivers to pursue treatments, even though they deemed them unreasonable. We discuss how this law may be perverted. Legal procedures may result in the units' disorganisation and give rise to caregivers' stress. Families' requests may be subtended by religious beliefs. French end-of-life law has benefits in theoretically constraining physicians to withhold or withdraw disproportionate therapies. These cases underline some caveats and the perverse effects of its literal reading.

Complications and early mortality in percutaneous endoscopic gastrostomy placement in lombardy: A multicenter prospective cohort study

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is the most common endoscopic procedure used to provide nutritional support.

AIM

To prospectively evaluate the mortality and complication incidences after PEG insertion or replacement.

METHODS

All patients who underwent PEG insertion or replacement were included. Details on patient characteristics, ongoing therapies, comorbidities, and indication for PEG placement/replacement were collected, along with informed consent form signatures. Early and late (30-day) complications and mortality were assessed.

RESULTS

950 patients (47.1% male) were enrolled in 25 centers in Lombardy, a region of Northern Italy. Patient mean age was 73 years. 69.5% of patients had ASA status 3 or 4. First PEG placement was performed in 594 patients. Complication and mortality incidences were 4.8% and 5.2%, respectively. The most frequent complication was infection (50%), followed by bleeding (32.1%), tube dislodgment (14.3%), and buried bumper syndrome (3.6%). At multivariable analysis, age (OR 1.08 per 1-year increase, 95% CI, 1.0-1.16, p = 0.010) and BMI (OR 0.86 per 1-point increase, 95% CI, 0.77-0.96, p = 0.014) were factors associated with mortality. PEG replacement was carried out in 356 patients. Thirty-day mortality was 1.8%, while complications occurred in 1.7% of patients.

CONCLUSIONS

Our data confirm that PEG placement is a safe procedure. Mortality was not related to the procedure itself, confirming that careful patient selection is warranted.

Critical Care Nurses' Perceptions of Parenteral and Enteral Nutrition at the End-of-Life in South Korea

PURPOSE

The purpose of this study was to explore the perceptions of critical care nurses regarding the withdrawal or withholding of enteral nutrition (EN) and parenteral nutrition (PN) at the end-of-life, which is not allowed according to the current law in South Korea.

METHODS

This was a cross-sectional study utilizing a self-report survey. The participants in the study were 141 nurses working in the intensive care units of a tertiary university hospital. The critical care nurses' general attitudes about EN and PN at the end-of-life were measured using the questionnaires developed by Lubart, Leibovitz, and Habot. The nurses responded to additional questions on whether withdrawal or withholding of EN or PN at the end-of-life should be legally allowed.

RESULTS

The mean scores of the general attitude items on EN ranged between 3.03 and 3.35 on a 5-point Likert scale where a value of 1 represents "strongly disagree" and a value of 5 represents "strongly agree," while those for PN ranged between 2.89 and 3.65. Respecting attitudes toward EN and PN, critical care nurses had more negative attitudes about stopping PN than EN. Regarding attitudes about whether patients should be legally able to refuse EN, 34.3% agreed, while 25.7% disagreed. For PN, 40.0% agreed, while 24.3% disagreed.

CONCLUSION

Discussions about making the withdrawal and withholding of artificial nutrition legal should be initiated. Moreover, education regarding evidence about the outcomes of EN and PN during end-of-life care and up-to-date clinical guidelines about it should be provided.

Perception of palliative medicine by health care professionals at a teaching community hospital: what is the key to a "palliative attitude"?

Background: With growing expense in chronic illness and end-of-life (EOL) care, population-based interventions are needed to reduce the health care cost and improve patients' quality of life. The authors believe that promotion of palliative medicine is one such intervention and this promotion depends on the acceptance of palliative medicine concepts by health care professionals. Aims of the studies: Perception of palliative medicine in chronic illness and in EOL care by health care professionals was learned in two studies carried out at a teaching community hospital 14 years apart. Participants and methods: Voluntary and anonymous surveys were randomly distributed among physicians, nurses, and social workers/case managers. Participants in the two studies presented two different groups of health care providers. Results of the studies: Results of the two studies were essentially similar. On most of the issues, respondents' perceptions were consistent with palliative medicine concepts and confidence in palliation grew over the 14-year period. The authors call this approach a "palliative attitude." Physicians with greater experience performed better in care planning. Younger physicians were more perceptive to withdrawal of care in futile cases. Participants' religion had no influence on perception of palliative medicine. Attendance of educational activities did not influence attitudes of health care professionals. Health care providers who favored involvement of palliative care teams in patients' management were better in care planning, interpretation of the DNR consent, use of opioids at the EOL, use of intensive care, and evaluation of the disease trajectory. Conclusion: The authors conclude that direct interaction between palliative and interdisciplinary teams in clinical practice is the key factor in the education of health care professionals, in the development of a "palliative attitude," and in the promotion of palliative medicine.

American College of Physicians Ethics Manual: Seventh Edition

Medicine, law, and social values are not static. Reexamining the ethical tenets of medicine and their application in new circumstances is a necessary exercise. The seventh edition of the American College of Physicians (ACP) Ethics Manual covers emerging issues in medical ethics and revisits older ones that are still very pertinent. It reflects on many of the ethical tensions in medicine and attempts to shed light on how existing principles extend to emerging concerns. In addition, by reiterating ethical principles that have provided guidance in resolving past ethical problems, the Manual may help physicians avert future problems. The Manual is not a substitute for the experience and integrity of individual physicians, but it may serve as a reminder of the shared duties of the medical profession.

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.

Home Enteral Nutrition: Updates, Trends, and Challenges

The true prevalence of home enteral nutrition (HEN) utilization is unclear and requires further study. HEN therapy has remained virtually unchanged for several decades. However, new trends in HEN are evolving; enteral nutrition is undergoing changes ranging from enteral feeding devices, ingredients used, practice innovations, and challenges with reimbursement. A 2006 Joint Commission call to action that reported 2 sentinel events related to misconnections set things into motion for the transition of enteral device connectors to become specific for enteral nutrition use, which will affect patients who receive HEN. Nutrition support clinicians are realizing that people fed enterally may also enjoy incorporating blended foods into their diets and may benefit from different nutrients and components (ie, phytonutrients, fiber, and prebiotics) present in natural foods, thereby resulting in the renaissance of food-based blenderized tube feedings. This article reviews HEN therapy data or the lack thereof, current practices, risks and benefits, future trends, and challenges with access devices, enteral feedings, and reimbursement. It also highlights areas where more research is needed, and it urges clinicians to get involved in legislative action or committees to facilitate improved processes and reimbursement for HEN.

Collaborative care: Using six thinking hats for decision making

AIM

To apply six thinking hats technique for decision making in collaborative care.

BACKGROUND

In collaborative partnerships, effective communications need to occur in patient, family, and health care professional meetings. The effectiveness of these meetings depends on the engagement of participants and the quality of the meeting process. The use of six thinking hats technique to engage all participants in effective dialogue is proposed.

DESIGN

Discussion paper.

DATA SOURCES

Electronic databases, CINAHL, Pub Med, and Science Direct, were searched for years 1990 to 2017.

IMPLICATIONS FOR NURSING

Using six thinking hats technique in patient family meetings nurses can guide a process of dialogue that focuses decision making to build equal care partnerships inclusive of all participants. Nurses will need to develop the skills for using six thinking hats technique and provide support to all participants during the meeting process.

CONCLUSION

Collaborative decision making can be augmented by six thinking hat technique to provide patients, families, and health professionals with opportunities to make informed decisions about care that considers key issues for all involved. Nurses who are most often advocates for patients and their families are in a unique position to lead this initiative in meetings as they network with all health professionals.

Artificial Hydration at the End of Life

Initiation or continuation of artificial hydration (AH) at the end of life requires unique considerations. A combination of ethical precedents and medical literature may provide clinical guidance on how to use AH at the end of life. The purpose of this review is to describe the ethical framework for and review current literature relating to the indications, benefits, and risks of AH at the end of life. Provider, patient, and family perspectives will also be discussed.

Bridging the Continuum: Nutrition Support in Palliative and Hospice Care

Clinicians and patients in today's technically focused healthcare environment are often faced with decisions of what should be done vs what could be done. The decision to provide or not provide nutrition support during palliative care and hospice care requires an understanding of and respect for patient wishes, an appreciation for the expectations of the patient and family, and open and effective communication. There can be confusion and disagreement concerning what nutrition therapies should be continued and which ones stopped. These decisions can be facilitated by answering the question: When do the burdens of nutrition support outweigh the benefit to the patient? The patient, family members, and healthcare providers should openly discuss and agree upon the goals of nutrition support during palliative care and hospice care.

Heterogeneity of patients receiving artificial nutrition in Japanese psychiatric hospitals: a cross-sectional study

AIM

Artificial nutrition, including tube feeding, continues to be given to dementia patients in numerous geriatric facilities in Japan. However, the clinical characteristics of patients receiving artificial nutrition have not been fully investigated. Therefore, we tried to evaluate the clinical features of those patients in this study.

METHODS

Various clinical characteristics of all inpatients at 18 of 20 psychiatric hospitals in Okayama Prefecture, Japan, with a percutaneous endoscopic gastrostomy tube, nasogastric tube, or total parenteral nutrition were evaluated.

RESULTS

Two hundred twenty-one patients (5.4% of all inpatients) had been receiving artificial nutrition for more than 1 month, and 187 (130 women, 57 men; 84.6% of 221 patients) were fully investigated. The mean age was 78.3 years old, and the mean duration of artificial nutrition was 29.8 months. Eighty-four patients (44.7% of 187 patients) were receiving artificial nutrition for more than 2 years. Patients with Alzheimer's disease (n = 78) formed the biggest group, schizophrenia (n = 37) the second, and vascular dementia (n = 26) the third.

CONCLUSION

About one-fifth of the subjects receiving artificial nutrition were in a vegetative state. More than a few patients with mental disorders, including schizophrenia, also received long-term artificial nutrition. We should pay more attention to chronic dysphasia syndrome in mental disorders.

Regional Comparison of Enteral Nutrition-Related Admission Policies in Skilled Nursing Facilities

BACKGROUND

Nursing home admission policies are one driver of increased and earlier gastrostomy placement, a procedure that is not always medically or ethically indicated among patients needing short-term nutrition support. This important clinical decision should be based upon patient prognosis, goals, and needs. We compared nursing home enteral nutrition-related admission policies in New York City and other regions of the United States. We also explored motivations for these policies.

METHODS

We conducted a telephone survey with skilled nursing facility administrators in New York City and a random sample of facilities throughout the United States about enteral nutrition-related admission policies. Survey data were matched with publically available data about facility characteristics from the Centers for Medicare and Medicaid Services. The relationship between facility location and admission policies was described with regression models. Reasons for these policies were thematically analyzed.

RESULTS

New York City nursing homes were significantly less likely to admit patients with nasogastric feeding tubes than were nursing homes nationwide, after we controlled for facility characteristics (odds ratio = 0.111; 95% CI, 0.032-0.344). Reasons for refusing nasogastric tubes fell into 5 categories: safety, capacity, policy, perception of appropriate level of care, and patient quality of life.

CONCLUSION

Our findings indicate that enteral nutrition-related admission policies vary greatly between nursing homes in New York City and nationwide. Many administrators cited safety and policy as factors guiding their institutional policies and practices, despite a lack of evidence. This gap in research, practice, and policy has implications for quality and cost of care, length of hospital stay, and patient morbidity and mortality.

ESPEN guideline on ethical aspects of artificial nutrition and hydration

BACKGROUND

The worldwide debate over the use of artificial nutrition and hydration remains controversial although the scientific and medical facts are unequivocal. Artificial nutrition and hydration are a medical intervention, requiring an indication, a therapeutic goal and the will (consent) of the competent patient.

METHODS

The guideline was developed by an international multidisciplinary working group based on the main aspects of the Guideline on "Ethical and Legal Aspects of Artificial Nutrition" published 2013 by the German Society for Nutritional Medicine (DGEM) after conducting a review of specific current literature. The text was extended and introduced a broader view in particular on the impact of culture and religion. The results were discussed at the ESPEN Congress in Lisbon 2015 and accepted in an online survey among ESPEN members.

RESULTS

The ESPEN Guideline on Ethical Aspects of Artificial Nutrition and Hydration is focused on the adult patient and provides a critical summary for physicians and caregivers. Special consideration is given to end of life issues and palliative medicine; to dementia and to specific situations like nursing care or the intensive care unit. The respect for autonomy is an important focus of the guideline as well as the careful wording to be used in the communication with patients and families. The other principles of Bioethics like beneficence, non-maleficence and justice are presented in the context of artificial nutrition and hydration. In this respect the withholding and withdrawing of artificial nutrition and/or hydration is discussed. Due to increasingly multicultural societies and the need for awareness of different values and beliefs an elaborated chapter is dedicated to cultural and religious issues and nutrition. Last but not least topics like voluntary refusal of nutrition and fluids, and forced feeding of competent persons (persons on hunger strike) is included in the guideline.

ESPEN guidelines on nutrition in dementia

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

[Nutrition and hydration at the end of life]

At the end of life the pleasure function of alimentation is to be preferred to its nutritive function. Artificial nutrition and hydration in an enteral or parenteral way are artificial life support techniques. Artificial nutrition and hydration are systematically justified for patients in curative phase that require it but not for patients in a terminal or agonal phase. The fear of death from hunger and thirst is not justified. It is more relevant of a symbolic and phantasmic dimension than of an objective reality. The practice of oral care is much more effective than installing an artificial hydration to improve the comfort of a patient at the very end of life. Withdrawing or withholding an artificial nutrition and hydration can prevent an unreasonable obstinacy prohibited by law.

Enteral Nutrition for Older Adults in Healthcare Communities

Older adults living in healthcare communities (HCCs) have multiple comorbidities and are at increased risk of malnutrition and unintended weight loss. Aging affects nearly every system as well as body composition and structure, causing physiological changes that can affect nutrition status. A significant percentage (56%) of residents who live in nursing facilities require extensive help to eat and have dental problems such as ill-fitting dentures, missing teeth, and swallowing problems, which can lead to inadequate caloric intake and unintended weight loss. Alzheimer disease or dementia is prevalent in both nursing facilities and in assisted living/residential care communities, where it affects 45% of older adults. In cognitively impaired residents, most tube feeding placements occur in the acute care setting and result in significant use of additional healthcare resources, along with high postinsertion mortality rates within 60 days of insertion. Nursing facilities receiving Medicare or Medicaid funding must abide by state and federal regulations and undergo rigorous surveys while balancing complex decisions related to initial placement of feeding tubes. Healthcare professionals must recognize the importance of establishing nutrition treatment goals that are resident centered and that respect the unique values and personal decisions of the older adult. Informed choice, resident-centered care decisions, and the review of living wills and/or advance directives are essential in the decision-making process. After enteral nutrition is started, healthcare practitioners must carefully review the physician's orders and administer and monitor the resident's tolerance, checking for potential complications.

Medically assisted nutrition for adult palliative care patients

BACKGROUND

Many palliative care patients have a reduced oral intake during their illness. The management of this can include the provision of medically assisted nutrition with the aim of prolonging the length of life of a patient, improving their quality of life, or both. This is an updated version of the original Cochrane review published in Issue 4, 2008.

OBJECTIVES

To determine the effect of medically assisted nutrition on the quality and length of life of palliative care patients.

SEARCH METHODS

We identified studies from searching Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, CANCERLIT, Caresearch, Dissertation abstracts, SCIENCE CITATION INDEX and the reference lists of all eligible trials, key textbooks and previous systematic reviews. The date of the latest search was 26 March 2014.

SELECTION CRITERIA

All relevant randomised controlled trials (RCTs) or prospective controlled trials (if no RCTs were found).

DATA COLLECTION AND ANALYSIS

We found no RCTs or prospectively controlled trials that met the inclusion criteria.

MAIN RESULTS

The original review identified four prospective non-controlled trials and the updated search in 2014 identified one more (plus an updated version of a Cochrane review on enteral feeding in motor neuron disease). There were five prospective non-controlled trials (including one qualitative study) that studied medically assisted nutrition in palliative care participants, and one Cochrane systematic review (on motor neuron disease that found no RCTs), but no RCTs or prospective controlled studies.

AUTHORS' CONCLUSIONS

Since the last version of this review, we found no new studies. There are insufficient good-quality trials to make any recommendations for practice with regards to the use of medically assisted nutrition in palliative care patients.

Medically assisted hydration for adult palliative care patients

BACKGROUND

Many palliative care patients have reduced oral intake during their illness. The management of this can include the provision of medically assisted hydration with the aim of prolonging the life of a patient, improving their quality of life, or both. This is an updated version of the original Cochrane review published in Issue 2, 2008, and updated in February 2011.

OBJECTIVES

To determine the effect of medically assisted hydration in palliative care patients on their quality and length of life.

SEARCH METHODS

We identified studies by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, CANCERLIT, Caresearch, Dissertation abstracts, SCIENCE CITATION INDEX and the reference lists of all eligible studies, key textbooks and previous systematic reviews. The date of the latest search conducted on CENTRAL, MEDLINE and EMBASE was March 2014.

SELECTION CRITERIA

All relevant randomised controlled trials (RCTs) or prospective controlled studies of medically assisted hydration in palliative care patients.

DATA COLLECTION AND ANALYSIS

We identified six relevant studies for this update. These included three RCTs (222 participants), and three prospective controlled trials (360 participants). Two review authors independently assessed the studies for quality and validity. The small number of studies and the heterogeneity of the data meant that a quantitative analysis was not possible, so we included a description of the main findings.

MAIN RESULTS

One study found that sedation and myoclonus (involuntary contractions of muscles) scores were improved more in the intervention group. Another study found that dehydration was significantly higher in the non-hydration group, but that some fluid retention symptoms (pleural effusion, peripheral oedema and ascites) were significantly higher in the hydration group. The other four studies (including the three RCTs) did not show significant differences in outcomes between the two groups. The only study that had survival as an outcome found no difference in survival between the hydration and control arms.

AUTHORS' CONCLUSIONS

Since the last version of this review, we found one new study. The studies published do not show a significant benefit in the use of medically assisted hydration in palliative care patients; however, there are insufficient good-quality studies to inform definitive recommendations for practice with regard to the use of medically assisted hydration in palliative care patients.

Artificial nutrition and hydration in Catholic healthcare: balancing tradition, recent teaching, and law

Roman Catholics have a long tradition of evaluating medical treatment at the end of life to determine if proposed interventions are proportionate and morally obligatory or disproportionate and morally optional. There has been significant debate within the Catholic community about whether artificially delivered nutrition and hydration can be appreciated as a medical intervention that may be optional in some situations, or if it should be treated as essentially obligatory in all circumstances. Recent statements from the teaching authority of the church have attempted to clarify this issue, especially for those with a condition known as the persistent vegetative state. I argue that these recent teachings constitute a "general norm" whereby artificial nutrition and hydration are considered obligatory for most patients, but that these documents allow for exception in cases of complication from the means used to deliver nutrition and hydration, progressive illness, or clear refusal of such treatment by patients. While the recent clarifications do not constitute a major deviation from traditional understanding and will rarely conflict with advance directives or legal statutes, there may be rare instances in which remaining faithful to church teaching may conflict with legally enshrined patient prerogatives. Using the Texas Advance Directives Act as an example, I propose ways in which ethics committees can remain faithful to their Roman Catholic identity while respecting patient autonomy and state law pertaining to end of life health care.

Judging the quality of mercy: drawing a line between palliation and euthanasia

Clinicians frequently worry that medications used to treat pain and suffering at the end of life might also hasten death. Intentionally hastening death, or euthanasia, is neither legal nor ethically appropriate in children. In this article, we explore some of the historical and legal background regarding appropriate end-of-life care and outline what distinguishes it from euthanasia. Good principles include clarity of goals and assessments, titration of medications to effect, and open communication. When used appropriately, medications to treat symptoms should rarely hasten death significantly. Medications and interventions that are not justifiable are also discussed, as are the implications of palliative sedation and withholding fluids or nutrition. It is imperative that clinicians know how to justify and use such medications to adequately treat suffering at the end of life within a relevant clinical and legal framework.

Position of the academy of nutrition and dietetics: ethical and legal issues in feeding and hydration

It is the position of the Academy of Nutrition and Dietetics that individuals have the right to request or refuse nutrition and hydration as medical treatment. Registered dietitians (RDs) should work collaboratively as part of the interprofessional team to make recommendations on providing, withdrawing, or withholding nutrition and hydration in individual cases and serve as active members of institutional ethics committees. RDs have an active role in determining the nutrition and hydration requirements for individuals throughout the life span. When individuals choose to forgo any type of nutrition and hydration (natural or artificial), or when individuals lack decision-making capacity and others must decide whether or not to provide artificial nutrition and hydration, RDs have a professional role in the ethical deliberation around those decisions. Across the life span, there are multiple instances when nutrition and hydration issues create ethical dilemmas. There is strong clinical, ethical, and legal support both for and against the administration of food and water when issues arise regarding what is or is not wanted by the individual and what is or is not warranted by empirical clinical evidence. When a conflict arises, the decision requires ethical deliberation. RDs' understanding of nutrition and hydration within the context of nutritional requirements and cultural, social, psychological, and spiritual needs provide an essential basis for ethical deliberation. RDs, as health care team members, have the responsibility to promote use of advanced directives. RDs promote the rights of the individual and help the health care team implement appropriate therapy.

Parental perceptions of forgoing artificial nutrition and hydration during end-of-life care

BACKGROUND AND OBJECTIVE

Forgoing artificial nutrition and hydration (FANH) in children at the end of life (EOL) is a medically, legally, and ethically acceptable practice under specific circumstances. However, most of the evidence on FANH involves dying adults. There is a paucity of pediatric evidence to guide health care providers' and parents' decision-making around this practice. Objectives were (1) to explore the experiences of bereaved parents when a decision had been made to FANH during EOL care for their child and (2) to describe the perceived quality of death in these children, as reported by their parents.

METHODS

This was a qualitative study using in-depth interviews with parents whose children died after a decision to FANH. Parental perceptions about the experience and their child's quality of death were explored. Interviews were audiotaped and transcribed, then data were analyzed by using interpretive description methodology.

RESULTS

All parents were satisfied with their decision to FANH and believed that their child's death was generally peaceful and comfortable. The child's perceived poor quality of life was central to the decision to FANH, with feeding intolerance often contributing to this perception. Despite overall satisfaction, all parents had doubts and questions about the decision and benefited from ongoing assurances from the clinical team.

CONCLUSIONS

FANH in children at the EOL is an acceptable form of palliation for some parents and may contribute to a death that is perceived to be peaceful and comfortable. In situations in which FANH may be a reasonable possibility, physicians should be prepared to introduce the option.

Medical ethics in pediatric critical care

Ethically charged situations are common in pediatric critical care. Most situations can be managed with minimal controversy within the medical team or between the team and patients/families. Familiarity with institutional resources, such as hospital ethics committees, and national guidelines, such as publications from the American Academy of Pediatrics, American Medical Association, or Society of Critical Care Medicine, are an essential part of the toolkit of any intensivist. Open discussion with colleagues and within the multidisciplinary team can also ensure that when difficult situations arise, they are addressed in a proactive, evidence-based, and collegial manner.

Clinical evaluation of percutaneous endoscopic gastrostomy tube feeding in Japanese patients with dementia

AIM

The aim of this study was to clinically evaluate percutaneous endoscopic gastrostomy (PEG) tube feeding of elderly Japanese patients with dementia.

METHOD

The records of the 155 patients with dementia who underwent PEG in Juntendo Tokyo Koto Geriatric Medical Center were reviewed for pertinent clinical data, including diagnosis of dementia, place of stay before and after hospitalization, as well as survival rate, albumin levels, and incidence of aspiration pneumonia (AP) before and 6 months after PEG feeding. The latter three data of these patients were compared with those of 106 patients with dementia fed through a nasogastric (NG) tube.

RESULTS

Alzheimer's disease and vascular dementia were predominant. Fifty-three percent of the patients were admitted from their home; the number of discharges to homes decreased to 21.2%. The mean (SD) of the albumin levels was 2.9 (0.4) g/dl before feeding and 2.9 (0.6) g/dl after 6 months. Among the patients with AP before PEG tube feeding, 51.6% had an AP recurrence. Conversely, AP occurred in 9.4% of the patients without AP before feeding. The patient survival rate was higher by 27 months when using PEG tube than when using an NG tube.

CONCLUSION

PEG tube feeding in patients with dementia leads to preservation of status for a few years. Compared with NG tube feeding, PEG tube feeding did not induce AP due to impairment of intact swallowing function, and was associated with higher survival rate of approximately 2 years. However, PEG tube feeding does not seem to promote home medical care.

Food or medicine: ethnic variations in perceptions of advanced cancer patients and their caregivers regarding artificial hydration during the last weeks of life

PURPOSE

To identify whether advanced cancer patients receiving home hospice care and their primary caregivers view artificial hydration (AH) as food or medicine, and the demographic and clinical factors influencing these perceptions.

METHODS

Participants were enrolled in a randomised, double-blind controlled trial examining the efficacy of AH in cancer hospice patients. In-depth interviews at days 1 and 4 of study enrolment explored the meanings attributed to AH at the end of life. Responses to the question, 'Are these fluids more like food or more like medicine?' were categorised as 'food', 'medicine', 'both' or 'other'. χ(2) analyses were conducted with data from 122 interviews (54 patients and 68 caregivers) to identify differences between patients and caregivers, and by gender, age, ethnicity and caregiver relationship. Predictors of perceptions were identified using logistic regression analysis.

RESULTS

Overall, 47 participants (38%) understood the fluids to be more like food, 41 (34%) as medicine, 17 (14%) as both, and 17 (14%) as 'other'. Ethnic minority participants (n=34, 66%) were significantly more likely than non-Hispanic European Americans (n=30, 42%) to view AH as food, or both as food and medicine (p=0.034). Ethnic differences persisted in the final regression model (OR 2.7; 95% CI 1.3 to 5.7, p=0.010). No significant differences were detected between patients and caregivers, or across gender, age, caregivers' relationship to the patients, group assignment, disease severity or cancer type.

CONCLUSIONS

AH was perceived as food/nutrition by many cancer patients and caregivers in the study, particularly among ethnic minorities. This perception may lead to greater distress if fluids are discontinued or withheld. Asking patients/caregivers about their AH perceptions may enhance patient/provider communication and culturally appropriate end-of-life care.

Initiating artificial nutrition support: a clinical judgement analysis

BACKGROUND

Variations in the practice of artificial nutrition are partly a result of the judgements of clinicians. Little is known about these judgements, the decision processes used or the quality of the decisions that arise. The methodology of clinical judgement analysis describes and explains judgemental differences between clinicians and offers a window into why clinician choices sometimes fail to correspond with current best practice guidelines.

METHODS

A clinical judgement analysis with 27 clinicians using two judgement tasks was carried out. Clinicians expressed their 'likelihood of feeding' and 'whether or not they would initiate artificial nutrition support' in response to 54 patient scenarios. Measures of agreement between clinicians, the degree of linear reasoning employed, their judgemental consistency and concordance with National Institute for Health and Clinical Excellence (NICE) guidelines were assessed.

RESULTS

Clinicians' judgements varied substantially both in the amount of information employed and the weighting given to information. Clinicians had only moderate agreement with NICE recommendations and overestimated the need for artificial nutrition support. Suboptimal judgements were consistently applied by clinicians. When clinicians reasoned in more linear ways, their judgements and decisions improved.

CONCLUSIONS

Overestimating the need for artificial nutritional support may inflate health service costs and increase risks for patients unnecessarily. A better understanding by clinicians of the information needed (as well as how to use it) for artificial nutrition support initiation may help improve clinical decision-making.

The meaning of parenteral hydration to family caregivers and patients with advanced cancer receiving hospice care

CONTEXT

In the U.S., patients with advanced cancer who are dehydrated or have decreased oral intake almost always receive parenteral hydration in acute care facilities but rarely in the hospice setting.

OBJECTIVES

To describe the meaning of hydration for terminally ill cancer patients in home hospice care and for their primary caregivers.

METHODS

Phenomenological interviews were conducted at two time points with 85 patients and 84 caregivers enrolled in a randomized, double-blind, controlled trial examining the efficacy of parenteral hydration in patients with advanced cancer receiving hospice care in the southern U.S. Transcripts were analyzed hermeneutically by the interdisciplinary research team until consensus on the theme labels was reached.

RESULTS

Patients and their family caregivers saw hydration as meaning hope and comfort. Hope was the view that hydration might prolong a life of dignity and enhance quality of life by reducing symptoms such as fatigue and increasing patients' alertness. Patients and caregivers also described hydration as improving patients' comfort by reducing pain; enhancing the effectiveness of pain medication; and nourishing the body, mind, and spirit.

CONCLUSION

These findings differ from traditional hospice beliefs that dehydration enhances patient comfort, given that patients and their families in the study viewed fluids as enhancing comfort, dignity, and quality of life. Discussion with patients and families about their preferences for hydration may help tailor care plans to meet specific patient needs.

Ethical issues in nutrition support of severely disabled elderly persons: a guide for health professionals

Providing or withholding nutrition in severely disabled elderly persons is a challenging dilemma for families, health professionals, and institutions. Despite limited evidence that nutrition support improves functional status in vulnerable older persons, especially those suffering from dementia, the issue of nutrition support in this population is strongly debated. Nutrition might be considered a basic need that not only sustains life but provides comfort as well by patients and their families. Consequently, the decision to provide or withhold nutrition support during medical care is often complex and involves clinical, legal, and ethical considerations. This article proposes a guide for health professionals to appraise ethical issues related to nutrition support in severely disabled older persons. This guide is based on an 8-step process to identify the components of a situation, analyze conflicting values that result in the ethical dilemma, and eventually reach a consensus for the most relevant plan of care to implement in a specific clinical situation. A vignette is presented to illustrate the use of this guide when analyzing a clinical situation.

Prophylactic percutaneous endoscopic gastrostomy tube placement in treatment of head and neck cancer: a comprehensive review and call for evidence-based medicine

BACKGROUND

Patients with head and neck cancers (HNCs) are at increased risk of experiencing malnutrition, which is associated with poor outcomes. Advances in the treatment of HNCs have resulted in improved outcomes that are associated with severe toxic oral side effects, placing patients at an even greater risk of malnutrition. Prophylactic placement of percutaneous endoscopic gastrostomy (PEG) tubes before treatment may be beneficial in patients with HNC, especially those undergoing more intense treatment regimens. PEG tube placement, however, is not without risks.

METHODS

A comprehensive review of the literature was conducted.

RESULTS

Systematic evidence assessing both the benefits and harm associated with prophylactic PEG tube placement in patients undergoing treatment for HNC is weak, and benefits and harm have not been established.

CONCLUSIONS

More research is necessary to inform physician behavior on whether prophylactic PEG tube placement is warranted in the treatment of HNC.
