Nutritional status and quality of life in patients with percutaneous endoscopic gastrostomy (PEG) in practice: prospective one-year follow-up

Time trends and outcomes of gastrostomy placement in a Swedish national cohort over two decades

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) and laparoscopically inserted gastrostomy have become the gold standard for adult patients and children, respectively, requiring long-term enteral nutrition support. Procedure-related mortality is a rare event, often reported to be zero in smaller studies. National data on 30-d mortality and long-term survival rates after gastrostomy placement are scarce in the literature.

AIM

To study the use of gastrostomies in Sweden from 1998-2019 and to analyze procedure-related mortality and short-term (< 30 d) and long-term survival.

METHODS

In this retrospective, population-based cohort study, individuals that had received a gastrostomy between 1998-2019 in Sweden were included. Individuals were identified in the Swedish National Patient Register, and survival analysis was possible by cross-referencing the Swedish Death Register. The cohort was divided into three age groups: Children (0-18 years); adults (19-64 years); and elderly (≥ 65 years). Kaplan-Meier with log-rank test and Cox regression were used for survival analysis.

RESULTS

In total 48682 individuals (52% males, average age 60.9 ± 25.3 years) were identified. The cohort consisted of 12.0% children, 29.5% adults, and 58.5% elderly. An increased use of gastrostomies was observed during the study period, from 13.7/100000 to 22.3/100000 individuals (P < 0.001). The use of PEG more than doubled (about 800 to 1800/year), with a corresponding decrease in open gastrostomy (about 700 to 340/year). Laparoscopic gastrostomy increased more than ten-fold (about 20 to 240/year). Overall, PEG, open gastrostomy, and laparoscopic gastrostomy constituted 70.0% (n = 34060), 23.3% (n = 11336), and 4.9% (n = 2404), respectively. Procedure-related mortality was 0.1% (n = 44) overall (PEG: 0.05%, open: 0.24%, laparoscopic: 0.04%). The overall 30-d mortality rate was 10.0% (PEG: 9.8%, open: 12.4%, laparoscopic: 1.7%) and decreased from 11.6% in 1998-2009 vs 8.5% in 2010-2019 (P < 0.001). One-year and ten-year survival rates for children, adults, and elderly were 93.7%, 67.5%, and 42.1% and 79.9%, 39.2%, and 6.8%, respectively. The most common causes of death were malignancies and cardiovascular and respiratory diseases.

CONCLUSION

The annual use of gastrostomies in Sweden increased during the study period, with a shift towards more minimally invasive procedures. Although procedure-related death was rare, the overall 30-d mortality rate was high (10%). To overcome this, we believe that patient selection should be improved.

Micronutrient deficiency risk in long-term enterally fed patients: A systematic review

BACKGROUND AND AIMS

The micronutrient status of those receiving long-term enteral nutrition (EN) is poorly characterised. This systematic review was undertaken to determine prevalence of micronutrient deficiency in those receiving EN; the impact of the route of feeding; whether underlying disease or clinical factors were associated with micronutrient status; and the efficacy of interventions utilised to treat identified micronutrient deficiency.

METHODS

Electronic databases (CINAHL, Embase, PubMed, Web of Science) were searched to June 2021 for publications of primary investigation of micronutrient status in adults or children (>5yrs) receiving EN for >2 months in their usual residence. Independent assessment of compliance with inclusion criteria (Covidence®), data extraction of predefined data points, assessment of basis (Academy of Dietetics Quality Checklist) and certainty of evidence (GRADE) was assessed by at least two authors. (PROSPERO Registration: CRD42021261113).

RESULTS

Thirty-one studies (n = 744) met inclusion criteria. Deficiency was reported for copper, zinc, selenium, beta-carotene, and vitamins A, D and E: Only copper, zinc and selenium were associated with physical/haematological manifestations of deficiency. Jejunal feeding was associated with the development of copper deficiency and often required gastric or parenteral replacement to resolve the issue. Circumstances leading to deficiency included receiving feed products formulated with inadequate amounts of the implicated nutrient, low feed product volumes in the context of low macronutrient requirements, and nutritional decline prior to commencement of EN. Potential confounding factors such as inflammation were rarely accounted for. No studies investigated the contribution of underlying clinical condition on micronutrient status, and no other clinical or demographic features appeared to impact outcomes. Reported methods for treating identified deficiencies were usually successful in reversing deficiency symptoms. The certainty of evidence is very low, and the level of bias moderate to high.

CONCLUSION

While the evidence is very uncertain about the effect of long-term enteral feeding on the development of micronutrient deficiencies, clinicians should be alert to the possibility of micronutrient deficiency developing in long-term EN fed patients. Those who may be at increased risk are those receiving nutrition into the jejunum, those who meet macronutrient requirements in low volumes of EN product, and those commencing EN in a nutritionally deplete state. Further research and surveillance of micronutrient status with contemporary EN products and practices is required.

Quality of life assessment instruments in adult patients receiving home parenteral and enteral nutrition: A scoping review

Quality of life (QoL) assessment is important to evaluate the effect of the intervention for patients treated with home parenteral and enteral nutrition (HPEN). The purpose of this scoping review is to describe, evaluate, and recommend QoL instruments used in adult patients receiving HPEN. We used the Arksey and O'Malley framework and performed literature searches in five databases (PubMed, CINAHL, EMBASE, Web of Science, and Cochrane Library) to identify possibly relevant articles that focused on QoL of adult patients receiving HPEN. Of the studies that qualify for full-text screening, two independent researchers extracted data. Twenty-seven QoL instruments were identified, consisting of seven generic instruments, 12 disease-specific instruments, and eight therapy-specific instruments. The Short Form-36 was the most widely used generic instrument and the European Organization for Research and Treatment of Cancer QLQ-C30 was the most commonly employed disease-specific instrument. The recently developed therapy-specific tools, NutriQoL and HPN-QoL, were increasingly employed in studies either alone or in combination with other types of instruments. Important aspects of each instrument were summarized to aid clinicians and researchers in selecting an appropriate instrument when measuring the QoL of adult HPEN patients. Findings could also help to identify the necessity to develop new tools or to modify pre-existing ones to measure QoL of HPEN patients.

Factors predicting major complications, mortality, and recovery in percutaneous endoscopic gastrostomy

Background and Aim

Percutaneous endoscopic gastrostomy (PEG) has been used in patients with dysphagia and inadequate food intake via an oral route. Despite being a procedure with a high success rate, complications and death have been reported. The aim was to identify the factors related to major complications and mortality, as well as PEG removal prognostic factors due to improvement of their general condition.

Methods

Patient characteristics, comorbidities, laboratory data, concomitant medication, sedation, and indication for PEG placement were collected. Major complications, mortality, and PEG removal factors were assessed.

Results

A total of 388 patients were enrolled. There were 15 (3.9%) cases of major complications, with major bleeding being the most frequent in 6 (1.5%) patients. Corticosteroids were the independent variable associated with major complications (odds ratio [OR] 5.85; 95% confidence interval [CI] 1.71–20; P = <0.01). Advanced cancer (hazard ratio [HR] 0.5; 95% CI 0.3–1; P = 0.05), albumin (HR 0.6; 95% CI 0.4–0.9; P = <0.01), and C‐reactive protein (CRP) (HR 1.1; CI 1–1.2; P = 0.01) were considered risk factors for mortality. Previous pneumonia (HR 0.4; CI 0.2–0.9; P = 0.02) was a factor for permanent use of a PEG; however, oncological indication (HR 8.2; CI 3.2–21; P = <0.01) was factors for PEG withdrawal.

Conclusions

Chronic corticosteroid users potentially present with major complications. Low albumin levels and elevated CRP were associated with death. Previous aspiration pneumonia was a factor associated with permanent use of PEG; however, patients with oncological indication were the most benefited.

Nutritional Assessment in Adult Patients with Dysphagia: A Scoping Review

Malnutrition negatively affects the quality of life of patients with dysphagia. Despite the need for nutritional status assessment in patients with dysphagia, standard, effective nutritional assessments are not yet available, and the identification of optimal nutritional assessment items for patients with dysphagia is inadequate. We conducted a scoping review of the use of nutritional assessment items in adult patients with oropharyngeal and esophageal dysphagia. The MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases were searched to identify articles published in English within the last 30 years. Twenty-two studies met the inclusion criteria. Seven nutritional assessment categories were identified: body mass index (BMI), nutritional screening tool, anthropometric measurements, body composition, dietary assessment, blood biomarkers, and other. BMI and albumin were more commonly assessed in adults. The Global Leadership Initiative on Malnutrition (GLIM), defining new diagnostic criteria for malnutrition, includes the categories of BMI, nutritional screening tool, anthropometric measurements, body composition, and dietary assessment as its required components, but not the blood biomarkers and the “other” categories. We recommend assessing nutritional status, including GLIM criteria, in adult patients with dysphagia. This would standardize nutritional assessments in patients with dysphagia and allow future global comparisons of the prevalence and outcomes of malnutrition, as well as of appropriate interventions.

ESPEN guideline on clinical nutrition and hydration in geriatrics

BACKGROUND

Malnutrition and dehydration are widespread in older people, and obesity is an increasing problem. In clinical practice, it is often unclear which strategies are suitable and effective in counteracting these key health threats.

AIM

To provide evidence-based recommendations for clinical nutrition and hydration in older persons in order to prevent and/or treat malnutrition and dehydration. Further, to address whether weight-reducing interventions are appropriate for overweight or obese older persons.

METHODS

This guideline was developed according to the standard operating procedure for ESPEN guidelines and consensus papers. A systematic literature search for systematic reviews and primary studies was performed based on 33 clinical questions in PICO format. Existing evidence was graded according to the SIGN grading system. Recommendations were developed and agreed in a multistage consensus process.

RESULTS

We provide eighty-two evidence-based recommendations for nutritional care in older persons, covering four main topics: Basic questions and general principles, recommendations for older persons with malnutrition or at risk of malnutrition, recommendations for older patients with specific diseases, and recommendations to prevent, identify and treat dehydration. Overall, we recommend that all older persons shall routinely be screened for malnutrition in order to identify an existing risk early. Oral nutrition can be supported by nursing interventions, education, nutritional counseling, food modification and oral nutritional supplements. Enteral nutrition should be initiated if oral, and parenteral if enteral nutrition is insufficient or impossible and the general prognosis is altogether favorable. Dietary restrictions should generally be avoided, and weight-reducing diets shall only be considered in obese older persons with weight-related health problems and combined with physical exercise. All older persons should be considered to be at risk of low-intake dehydration and encouraged to consume adequate amounts of drinks. Generally, interventions shall be individualized, comprehensive and part of a multimodal and multidisciplinary team approach.

CONCLUSION

A range of effective interventions is available to support adequate nutrition and hydration in older persons in order to maintain or improve nutritional status and improve clinical course and quality of life. These interventions should be implemented in clinical practice and routinely used.

PEG Insertion in Patients With Dementia Does Not Improve Nutritional Status and Has Worse Outcomes as Compared With PEG Insertion for Other Indications

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) tubes are commonly utilized as a method of enteral feeding in patients unable to obtain adequate oral nutrition. Although some studies have shown improved mortality in select populations, the safety and effectiveness of PEG insertion in patients with dementia compared with those with other neurological diseases or head and neck malignancy remains less well defined.

OBJECTIVE

To evaluate the nutritional effectiveness, rate of rehospitalization, and risk of mortality among patients with dementia compared with patients with other neurological diseases or head and neck cancers who undergo PEG placement.

MATERIALS AND METHODS

We conducted a retrospective analysis from a prospective database of patients who underwent PEG placement at an academic tertiary center between 2008 and 2013. The following data were collected: indication for PEG, patient demographics, biochemical markers of nutritional status rehospitalization, and survival rates.

RESULTS

During the study period, 392 patients underwent PEG tube placement. Indications for PEG were dementia (N=165, group A), cerebrovascular accident (N=124, group B), and other indications such as oropharyngeal cancers and motor neuron disease (N=103, group C). The mean follow-up time after PEG was 18 months (range, 3 to 36 mo). No differences in baseline demographics were noted. PEG insertion in the dementia (group A) neither reduced the rehospitalization rate 6 months' postprocedure compared with groups B and C (2.45 vs. 1.86 and 1.65, respectively; P=0.05), nor reduced the mortality rate within the first year post-PEG placement (75% vs. 58% and 38% for groups A, B, and C, respectively, P=0.001), as well, it did not improve survival at 1 month after the procedure (15% vs. 3.26% and 7.76%, for groups A, B, C, respectively, P<0.01). The presence of dementia was also associated with shorter mean time to death (7.2 vs. 8.85 and 8 mo for groups A, B, C, respectively, P<0.05). The rate of improvement of the nutritional biomarker albumin was lower in the dementia group [3.1. to 2.9 vs. 3.2 to 3.3 and 3 to 3.3 g/dL for groups A, B, and C, respectively (P<0.02)]. Multivariate regression analysis showed that the presence of dementia was an independent predictor for mortality rate within the first year and 1-month mortality rate in patients undergoing PEG insertion with odds ratio 3.22 (95% confidence interval, 1.52-4.32) and odds ratio 2.52 (95% confidence interval, 1.22-3.67).

CONCLUSIONS

PEG insertion in patients with dementia neither improve both short-term and long-term mortality nor rehospitalization rate as compared with patients who underwent PEG placement for alternate indications such as other neurological diseases or head and neck malignancy and even was associated with shorter time to death. Furthermore, PEG insertion in patients with dementia did not improve albumin. Therefore, careful selection of patients with dementia is warranted before PEG placement weighing the risks and benefits on a personalized basis.

Is There a Difference in Metabolic Outcome Between Different Enteral Formulas?

BACKGROUND

Despite appropriate enteral nutrition, many elderly patients do not reach a good metabolic outcome. Two nutrition formulas are commonly used in Israel with no evidence-based medicine to indicate preference of one over the other.

METHODS

We describe a 2-month observational study of patients fed by 1 of the 2 formulas. The first (Osmolite, Abbott Company, Abbott Park, IL) is without fiber, and the second (Easy Fiber, Easyline Company Givataim, Israel) in addition to containing fiber is also richer in protein, vitamins, and minerals. The formula was selected by the primary care physician before enrollment in the study and was not influenced by the investigators. Routine blood tests as well as body weight were monitored at the start of enteral feeding and during the 2 months following as part of the regular follow-up.

RESULTS

Fifty-seven patients were fed with the regular formula and 77 with the enriched one. No statistically significant differences were noted between the groups during the follow-up period, in body weight, cholesterol levels, total lymphocyte count, renal function tests, or electrolyte balance. However, in the enriched formula group there was a significant decrease in glucose (p < .05), and increase in albumin (p < .05) and hemoglobin (p = .01) levels.

CONCLUSIONS

Enteral feeding with enriched formula appears to improve albumin and hemoglobin levels as well as diabetic control, thus it may be more appropriate than the nonfiber diet for use in long-term care patients.

Severe hypernatremia as a predictor of mortality after percutaneous endoscopic gastrostomy (PEG) placement

BACKGROUND

Percutaneous endoscopic gastrostomy is the preferred option for providing enteral nutrition, allowing for an improvement in survival and quality of life.

AIM

To evaluate risk factors for early and delayed mortality after gastrostomy placement.

METHODS

A single-center retrospective analysis of a prospectively-collected database including all patients undergoing gastrostomy placement for enteral nutrition was performed. Two operators performed all the procedures according to the most recent guidelines.

RESULTS

Analysis included data on 438 patients [178 male; 80.5 (72-86) year-old]. Indications for PEG were stroke (34.0%), dementia (31.3%), neurodegenerative disorders (18.5%), coma (9.1%) and cancer (7.1%). No periprocedural adverse events was observed. Mean survival was 14.6±3.4months; 1-month and 3-month mortality rates were 4.0% and 8.1%, respectively. Severe hypernatremia (≥150mmol/L) was independently related to 1-month mortality (odds ratio 25.4; P<0.0001), while C-reactive protein level>4.3mg/dL was independently related to 3-month mortality (odds ratio 5.3; P=0.003). Kaplan-Meier and Cox-regression analysis identified male gender (hazard ratio 2.32; P=0.0002), severe hypernatremia (hazard ratio 4.3; P<0.0001), C-reactive protein>4.3mg/dL (hazard ratio 3.5; P=0.0014), leukocytosis (hazard ratio 1.97; P=0.0036) and presence of underlying malignancy (hazard ratio 2.4; P=0.0013) as independent risk factors for long-term mortality.

DISCUSSION

Presence of severe hypernatremia and increased C-reactive protein levels were strongly correlated with early and delayed mortality in our population. Studies are necessary to understand whether correcting underlying dehydration and inflammation further improves patients' outcomes.

Enteral Nutrition Support of Head and Neck Cancer Patients

Patients with head and neck cancer are at high risk for malnutrition due to dysphagia from the tumor and treatment. Despite difficulty with oral intake, these patients usually have a normal stomach and lower gastrointestinal tract. Enteral nutrition support via percutaneous endoscopic gastrostomy (PEG) administered in the home by the patient helps to prevent weight loss, dehydration, nutrient deficiencies, treatment interruptions, and hospitalizations. It also improves quality of life. Successful management of these patients requires orderly care and follow-up by a multidisciplinary nutrition team.

Complication and mortality rate after percutaneous endoscopic gastrostomy are low and indication-dependent

OBJECTIVE

Percutaneous endoscopic gastrostomy (PEG) is often used for the feeding of patients with malnutrition due to dysphagia, and despite more than 30 years experience, numerous questions on its benefit remain. This was a prospective observational study to assess the safety of PEG.

MATERIAL AND METHODS

One hundred and nineteen patients mean age 63 years (21-91 years) who were admitted to the Hannover Medical School between November 2010 and March 2012 and had an indication for PEG according to the German guidelines were included. Primary endpoints were the following: reason for indication, date of in-hospital mortality after PEG insertion, death within 3 months after PEG placement, and complications.

RESULTS

Most patients (54.6%) received PEG for dysphagia caused by tumors and second (29.4%) for neurologic diseases with a minor proportion of dementia (3%). About 73% of our patients had no complications at all and only 10% suffered severe effects. We saw only 1 case of aspiration, which did not lead to pneumonia. The 30-day mortality was 10%, and no patient died as a result of the PEG procedure. Significantly more patients with neurologic disorders died within 24 weeks of PEG placement than tumor patients (60% versus 27.7%, respectively, p = 0.002, n = 100).

CONCLUSION

It is important to select patients receiving PEG very carefully. The patients' indications, their primary disease, and their capability for mental cooperation are essential. If these aspects are taken into account, PEG is a safe method with few mainly mild complications.

Malnutrition and quality of life in older people: a systematic review and meta-analysis

Although the effects of malnutrition on morbidity and mortality of older people is well established, there has been little work done to investigate the relationship between malnutrition and quality of life (QoL) in this population. In order to facilitate further research and to aggregate existing evidence into a clear overview, a systematic review was conducted. The objective was to identify the literature on the topic, review the findings systematically, and assess the association between nutritional status and QoL. MEDLINE, EMBASE, CINAHL and Web of Science were searched for relevant studies published up to April 2011. References within identified studies also searched. The primary author extracted all data using a purpose-built form, and evaluated the quality of the studies using a published checklist. A second reviewer checked a random sample of articles independently. Evidence in the current review comes from both cohort studies and intervention trials. Results from the former suggested that individuals with malnutrition are more likely to experience poor QoL (OR: 2.85; 95% CI: 2.20-3.70, p<0.001). Consistent with this, interventions designed to improve nutritional status can also lead to significant improvements in QoL, both physical (standard mean difference 0.23, CI: 0.08-0.38, p=0.002) and mental aspects (standard mean difference 0.24, CI: 0.11-0.36, p<0.001). However, the results should be interpreted with caution in view of the poor quality of the included studies and the heterogeneity of methods employed in the assessment of both nutritional status and QoL. Future studies should carefully characterise their participants and use standardised parameters for nutritional and QoL assessments in order to achieve better evaluation and comparability of study results.

Fructo-oligosaccharides and fibre in enteral nutrition has a beneficial influence on microbiota and gastrointestinal quality of life

OBJECTIVE

Intestinal microbiota is important in health and disease. The aim of this study was to evaluate the effect of fructo-oligosaccharides (FOS) and fibre-enriched tube feeding on quality of life and intestinal microbiota (faecal Bifidobacteria).

MATERIAL AND METHODS

Nineteen out of 59 home-living, tube-feeding-dependent, adult patients and matched healthy controls were included in this randomized, double-blind study. After a washout period, patients received either no residue tube feeding (non-FOS group) or FOS and fibre-enriched tube feeding (FOS group). Quality of life as defined by the Gastrointestinal Quality of Life Index (GIQLI) and quantification of faecal Bifidobacteria were determined.

RESULTS

At baseline, GIQLI scores in controls and patients were 88+/-12 and 67+/-14, respectively (p=0.001). Following 6 weeks' intervention, GIQLI scores remained stable (65+/-14 versus 67+/-17) in the FOS group, whereas the non-FOS group values decreased (68+/-17 versus 64+/-19). Baseline faecal samples contained 2. 1x 10(7)+/-3.5 x 10(7) and 2.1 x 10(6)+/-5.6 x10(6)Bifidobacteria (p=0.002) in controls and patients, respectively, with no differences between patient groups. During the intervention, this number remained stable in the FOS group (0.7 x 10(6)+/-1.3 x 10(6) versus 1.0 x 10(6)+/-1.3 x 10(6) baseline versus end-point), but decreased in the non-FOS group (3.6 x1 0(6)+/-8.0 x 10(6) versus 2.5 x 10(4)+/-4.0 x 10(4)). GIQLI scores were correlated with the number of faecal Bifidobacteria (r=0.41, p=0.007).

CONCLUSIONS

The GIQL score for the tube-fed patients increased with the number of faecal Bifidobacteria, although in a non-linear way, and addition of FOS increased the number of Bifidobacteria. This suggests that prebiotic tube feeding may lead to a change in intestinal microbiota that could induce an increased quality of life in these patients.

Quality of life and enteral nutrition

PURPOSE OF REVIEW

The quality of life is in essence, the patients' subjective view of their own health status and can add another dimension to the evaluation of a treatment as the enteral nutrition.The recent clinical investigations on this topic are critically summarized in this review.

RECENT FINDINGS

Three areas of potential impact of enteral nutrition on quality of life of patients have been identified: elderly and neurological patients, cancer patients and patients with anorexia nervosa.A major problem is the difficulty to define quality of life, due to the holistic and subjective nature of this dimension. Moreover, many patients require help to complete the forms of the questionnaire. Finally, many factors besides the enteral nutrition can affect the quality of life of these patients, namely the basic condition and the primary disease of the patients.

SUMMARY

Although the enteral nutrition often represents a life-saving procedure, this does not necessarily translate in an appreciation of a better quality of life by the patients.Additional factors as the gustatory deprivation and the loss of social contacts usually associated with eating and the frequent problems related to tube function and tube-feeding represent severe limitations to a good quality of life of these patients.

A pilot study exploring the factors that influence the decision to have PEG feeding in patients with progressive conditions

This original pilot study was conducted to explore and understand the factors that influence a patient's decision-making when considering percutaneous endoscopic gastrostomy placement for nonoral nutrition and hydration supplementation. Seven patients living with progressive dysphagic symptoms who had made a decision about percutaneous endoscopic gastrostomy placement were interviewed and their responses analyzed using the constant comparison method. All participants felt they had no option other than to accept the percutaneous endoscopic gastrostomy. The impact of visible physical deterioration and medical opinion were the most powerful influences on patients' decisions. Patients' perception of their involvement in the decision varied. This was linked to the amount and timing of information supplied and support they felt they received. Few patients have prior knowledge of tube feeding and rely heavily on medical advice. Effective communication by healthcare professionals can promote an environment that is supportive of patients' involvement in decisions. Adequate preparation time is vital if patients are to stop feeling uninvolved or peripheral to the decision-making process. Multidisciplinary teams need to address their working practices so that they do not intimidate patients, but rather empower patients in their decision-making.

Resolving End-of-Life Ethical Concerns: Important Palliative Care Practice Development Issues for Acute Medicine in Australia

Historically palliative care research has focused on issues associated within the hospice and palliative care system. The findings presented in this manuscript reverse this assumption to argue that significant palliative care issues can only be understood if the focus is on the acute care system. Although a major proportion of deaths happen in the acute hospital setting, the acute care clinicians are the gate keepers to the palliative system. In short, understanding the ethical decision making of acute care professionals in relation to end-of-life care can illuminate many important palliative care practice development issues. The findings indicate that all professional groups in this study of an acute medical ward find end-of-life issues the most challenging of all the ethical challenges.

Home percutaneous endoscopic gastrostomy feeding: perceptions of patients, carers, nurses and dietitians

AIM

This paper is a report of a study to compare the perceptions of adult patients, family carers, nurses and dietitians regarding home percutaneous endoscopic gastrostomy feeding.

BACKGROUND

Healthcare professionals have a major role in patient selection for gastrostomy placement and the provision of aftercare but it is not clear if patients, their carers and healthcare professionals have similar perceptions of the initiation and delivery of feeding and of the care in general.

METHOD

A cross-sectional mixed-method study using purposive sampling, semi-structured interviews and questionnaires was performed. Interviews were undertaken during 2005 with adult patients and carers of adults receiving home feeding. A questionnaire containing comparable questions was distributed to the lead district nurse and dietitian providing the individual patient's care. Binomial regression was used to analyse any differences in perceptions across the groups of respondents.

RESULTS

Nurses and dietitians had similar perceptions of gastrostomy feeding in adults. Family carers' perceptions matched those of professionals more closely than did those of patients. The greatest difference in perceptions was between patients and their family carers. Respondents' views about success of feeding and the appropriateness of the feeding regimen were similar, but greater differences existed regarding quality of life, withdrawal of feeding and choice in decision-making about tube placement.

CONCLUSION

There is a need for increased patient and carer involvement in decision-making and for sufficient, appropriate information to facilitate informed decision-making. Practitioners who involve carers in decision-making, where patients lack capacity, need to be aware that carers may not represent the views of patients.

Patients experience with long-term percutaneous endoscopic gastrostomy feeding following primary surgery for oral and oropharyngeal cancer

Percutaneous endoscopic gastrostomy feeding (PEG) has an important role in providing nutritional support in selected patients undergoing treatment for oral and oropharyngeal cancer. Although morbidity data have been published there is very little from the patient perspective. The aim of this project was to devise, pilot and survey a PEG specific questionnaire and relate outcomes to health-related quality of life. A cross-sectional survey was conducted in April 2005 of patients who were alive and disease free and treated by primary surgery for oral and oropharyngeal squamous cell carcinoma between 1992 and June 2004. The survey comprised the University of Washington Quality of Life questionnaire and a 24 item PEG questionnaire. Of 344 alive and disease free patients, 243 (71%) responded. Clinical characteristics of responders and non responders were similar. Mean age of responders was 65 (SD 12) and 59% were male. There were 193 (79%) patients who never had a PEG as part of their treatment, 30 (12%) who had their PEG removed (median 7 months), and 20 (8%) who still had a PEG (median 34 months). Patients with PEGs reported significant deficits in all UW-QOL domains compared to non-PEG or PEG-removed patients and also reported a much poorer quality of life. The major PEG related problems were not those of discomfort, leakage or blockage, but interference with family life, intimate relationships, social activities, and hobbies. More can be done to counsel and support patients with long-term PEG placement.

Percutaneous endoscopic gastrostomies: the burden of treatment from a patient perspective

AIM

This paper reports a study of patients' experiences of this relatively new technology, and explores possible strategies for defining, delineating and addressing patients' concerns, problems and needs.

BACKGROUND

The number of patients in the community relying on percutaneous endoscopic gastrostomy for their nutritional needs is increasing, but percutaneous endoscopic gastrostomy feeding is not problem-free. However, few studies report on its impact from a patient perspective.

METHODS

Twenty adults with long-term percutaneous endoscopic gastrostomies were interviewed in their own homes, using both semi-structured and structured approaches. Qualitative data were analysed thematically and related to a symptom checklist and an established quality of life measure, the Short Form-12.

FINDINGS

Most participants felt that insertion of a percutaneous endoscopic gastrostomy had been life-saving, but found that percutaneous endoscopic gastrostomy feeding came to dominate their lives and was associated with an appreciable "burden of treatment". Some, but not all, of the problems recounted were unavoidable: percutaneous endoscopic gastrostomy feeding inevitably imposed physical restrictions on mobility; 17/20 participants had experienced serious technical problems with their percutaneous endoscopic gastrostomy tubes. On structured questioning, all interviewees had some, potentially treatable, gastrointestinal symptoms, and eight had continuous problems. In some cases, the burden of treatment was exaggerated by being unanticipated and, for 13 patients, difficulties with care provided by non-specialist services. Describing this "burden of treatment" for each patient required both a narrative and a structured approach: without the symptom checklists, some important and treatable problems were missed. Both physical and mental health Short Form-12 scores were low, and mental health scores were congruent with the interview data.

CONCLUSIONS

It might be possible to reduce the "burden of treatment" identified by incorporating a structured approach to patient monitoring and by reviewing the occupational territories of specialist and non-specialist practitioners. Further research with larger numbers of participants is needed to explore the integration of narrative and quantitative data when determining patients' clinical needs.

A patient with dementia and cancer: to feed via percutaneous endoscopic gastrostomy tube or not?

Despite the lack of clear benefits of feeding via gastrostomy tube in dementia patients, its use has been increasing. The views of health professionals, patients and their carers differ widely about the perceived benefits, which makes decision-making difficult and stressful. The palliative care approach of facilitating better communication and end-of life care planning can help avoid inappropriate gastrostomy tube placements. A case of an elderly male with dementia and two malignancies is described, and the place of the palliative care approach is explored.

Complication rate lower after percutaneous endoscopic gastrostomy than after surgical gastrostomy: a prospective, randomized trial

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) has increasingly replaced surgical gastrostomy (SG) as the primary procedure for the long-term nutrition of patients with swallowing disorders. This prospective randomized study compares PEG with SG in terms of effectiveness and safety.

METHODS

This study enrolled 70 patients with swallowing disorders, mainly attributable to neurologic impairment. All the patients, eligible for both techniques, were randomized to PEG (pull method) or SG. The groups were comparable in terms of age, body mass index, and underlying diseases. Complications were reported 7 and 30 days after the operative procedure.

RESULTS

The procedures were successfully completed for all the patients. The median operative time was 15 min for PEG and 35 min for SG (p < 0.001). The rate of complications was lower for PEG (42.9%) than for SG (74.3%; p < 0.01). The 30-day mortality rates were 5.7% for PEG and 14.3% for SG (nonsignificant difference).

CONCLUSION

The findings show PEG to be an efficient method for gastrostomy tube placement with a lower complication rate than SG. In addition, PEG is faster to perform and requires fewer medical resources. The authors consider PEG to be the primary procedure for gastrostomy tube placement.

Ethical and legal aspects of enteral nutrition

European ethical and legal positions with regard to EN vary slightly from country to country but are based on a common tradition derived from Graeco Roman ideas, religious thought and events of the 20th century. The Hippocratic tradition is based on 'beneficience' (do good) and 'non-maleficience' (do no harm). Religious thinking is based upon the presumption of providing food and drink by whatever means unless burden outweighs benefit. The concept of 'autonomy' (the patients right to decide) arose following in the decades after the Second World War and is enshrined in Human Rights law. The competent patient has the right to participate in decision making and to refuse treatment although the doctor is not obliged to give treatment which he or she considers futile or against the patient's interests. The incompetent patient is protected by law. The fourth principle is that of 'justice' i.e. equal access to healthcare for all. The law regards withholding and withdrawing treatment as the same. It also defines the provision of food and drink by mouth as basic care and feeding by artificial means as a medical treatment. It requires doctors to act in the best interests of the patient.

Cachexia: pathophysiology and clinical relevance

Cachexia causes weight loss and increased mortality. It affects more than 5 million persons in the United States. Other causes of weight loss include anorexia, sarcopenia, and dehydration. The pathophysiology of cachexia is reviewed in this article. The major cause appears to be cytokine excess. Other potential mediators include testosterone and insulin-like growth factor I deficiency, excess myostatin, and excess glucocorticoids. Numerous diseases can result in cachexia, each by a slightly different mechanism. Both nutritional support and orexigenic agents play a role in the management of cachexia.
