Percutaneous endoscopic gastrostomy: a prospective analysis of hospital support required and complications following discharge to the community

Systematic review of service improvements for home enteral tube feeding in adults

BACKGROUND

Patients receiving home enteral tube feeding (HETF) have a high risk of complications and readmission to hospital. This study aims to evaluate effectiveness of staff- and/or patient-focused service-improvement strategies on clinical, patient-reported, and economic outcomes for patients receiving HETF across adult settings.

METHODS

The search was conducted using MEDLINE, EMBASE, and CINAHL databases. Quality of studies were appraised using the Cochrane Collaboration Risk of Bias tool and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) assessment.

RESULTS

Eleven studies met the inclusion criteria. Pooled data found targeted HETF education with patients, carers, and staff significantly improved knowledge immediately after education and was sustained at 3-6 months. Multimodal interventions, including the formation of specialist HETF teams, significantly reduced complications such as infection, gastrostomy blockage, tube displacement, and feed intolerance but do not significantly reduce unplanned hospital encounters (outpatient clinic visits, hospitalizations, and emergency presentations). Owing to the high risk of bias in the included studies, there is low-quality evidence to support staff training, patient education, and dedicated HETF teams.

CONCLUSION

This review highlights the need for further quality research to allow higher-level evidence for determining the usefulness of interventions aimed at improving outcomes for patients receiving HETF. Future research needs to include greater assessment of quality of life, quantification of the value of interventions in economic terms, and use of translational research frameworks. However, effective staff and patient education programs, along with comprehensive multidisciplinary care, should be considered standard care until a larger research base is developed.

Hospital Discharge on Enteral Nutrition is Associated with Increased Hospital Readmissions

Background: Enteral nutrition (EN) delivered via an enteric access device is employed to correct severe malnutrition and feed patients with pathology restricting oral intake, and is often initiated in the hospital. There are limited data on the clinical outcomes of patients discharged from the hospital on EN. We sought to assess whether discharge with enteral nutrition (DCEN) was independently associated with increased hospital readmissions and to assess the frequency of DCEN in our hospital.Methods: We conducted a retrospective cohort study of all hospital discharges from a tertiary care hospital between 7/2017 and 12/2019. The primary and secondary outcomes were 30- and 90-day readmissions respectively. We evaluated demographic and clinical characteristics of patients, nutrition status, and readmissions as reported in the electronic health record per hospital encounter. Logistic regressions were performed for 30- and 90-day readmissions based on DCEN.Results: Of 80,080 hospital encounters, 2527 (3.2%) encounters resulted in discharge with EN. 30-day readmissions occurred in 22.8% of encounters with DCEN and 12.5% of encounters without (p < 0.001). 90-day readmissions occurred in 35.1% and 20.4% of encounters with and without DCEN respectively (p < 0.001). The unadjusted odds ratio for 30-day readmissions for encounters with DCEN was 2.07 (CI 1.88-2.28). When adjusted for age, race, sex, Charlson Comorbidity Index, and malnutrition co-diagnosis, the odds ratio was 1.40 (CI 1.27-1.55).Conclusions: Patients with DCEN have a significantly higher likelihood of 30- and 90-day readmission. Targeted interventions and improved post-discharge care for this identified high-risk population may decrease hospital readmissions.[Box: see text].

A scoping review of best practices in home enteral tube feeding

Aims:

To review the experiences of healthcare professionals (HCPs) and service users on the provision and receipt of home enteral nutrition (HEN) in primary care settings, respectively.

Backgrounds:

HEN supports the nutritional needs of service users in primary care settings who are unable to meet their nutritional requirements through oral intake alone. While HEN supports service users to remain in their home, the provision of HEN services can be variable. The prevalence of HEN is increasing as health systems shift delivery of care from acute to primary care settings, and therefore the evolving needs of HCPs and service users in relation to HEN deserve exploration.

Methods:

Quantitative and qualitative studies were included if they described (1) practices that support best outcomes in adults on HEN and residing in their own homes and/or (2) service user and HCP experiences of HEN. Studies on the economics of HEN were included. Databases searched included MEDLINE/PubMed, EMBASE, Web of Science, and CINAHL. Publications up to March 2021 were included. A descriptive analytical approach was used to summarise the findings.

Findings:

Key themes included the importance of initial education to enable service users to adapt to HEN and the need for support from knowledgeable HCPs. Access to support from HCPs in primary care was limited, and some HCPs felt their knowledge of HEN was inadequate. Service users highlighted the significant impact of HEN on daily living and emphasised the need for support from a HEN team. HEN services were also associated with reduced hospital admissions, lengths of stay in hospital, and costs of hospitalisation.

Conclusions:

A specialist HEN service can manage enteral nutrition-related complications, reduce unnecessary hospital admissions, and improve quality of care and patient satisfaction. Further education of HCPs is needed on the provision of HEN.

Reducing outpatient gastrostomy tube complications

OBJECTIVE

To monitor the effectiveness of a multidisciplinary education protocol for gastrostomy tube (GT) use and care for patients to reduce complications postplacement.

METHODS

Baseline assessment included a preintervention/intervention design through quantitative measures to determine reduction in the number of GT complications postprocedure following implementation of a patient education protocol for 16 patients in the study.

INTERVENTION

A multidisciplinary approach was used in protocol development for standardizing patient education. Verbal, written, and hands-on demonstration methods for GT care were used to provide multiple education pathways to increase patient knowledge. Over the progression of 8 months (July 2019 to March 2020), patients with a new GT were followed postprocedure (1-2 weeks prior to starting radiation treatments) and throughout their course of radiation treatments (typically 6-7 weeks).

RESULTS

All 16 patients (100%) in the intervention group were included in the final analysis. GT complications were reduced from 91% in the preintervention group (n = 11) to 37% in the intervention group (n = 16). The most significant reduction occurred in technique issues, which decreased from 36% (n = 4) to 0%.

CONCLUSIONS

Implementation of a multidisciplinary approach with multiple educational sessions prior to GT placement and use led to increased patient knowledge and reduced GT complications.

Longitudinal complications associated with PEG: Rate and severity of 30-day and 1-year complications experienced by patients after primary PEG insertion

BACKGROUND AND AIMS

Percutaneous Endoscopic Gastrostomy (PEG) feeding is utilised in patients with exceptionally poor oral intake but is associated with both short and long-term complications. This study reviews longitudinal PEG complications and compares key subgroups.

METHODS

Single-centre retrospective observational study of all patients receiving PEG insertion between January 2016 and December 2018.

RESULTS

306 patients met the inclusion criteria. The mean age at insertion was 67 years. The majority were cared for in their own home (80.4%) by themselves or family (74.9%). 127 PEG tubes were inserted for dysphagia and 165 prophylactically prior to treatment for head and neck cancer. In the first 30 days 16.7% experienced a complication. The most frequently reported was peristomal pain (9.2%). In the first year, 35.6% experienced at least one complication, 12.4% two complications and 6.6% three complications and 6.5% required inpatient treatment for their complication. The most common was pain (14.4%) followed by site weeping, site infection and external overgranulation. Patients with dysphagia took longer to develop complications, had fewer complications and took longer to require management by members of the secondary care team than those with head and neck cancer. Discounting peristomal pain, there was no difference in total complications between patients caring for themselves when compared to those receiving professional input.

CONCLUSION

One third of patients will experience a complication related to their PEG tube over 1 year, but the majority are managed in an outpatient setting. This study has implications for planning support services and consenting and counselling patients pre-PEG-insertion.

Guidelines for gastrostomy tube placement and enteral nutrition in patients with severe, refractory hypoglycemia after gastric bypass

BACKGROUND

Postbariatric hypoglycemia (PBH) affects up to 38% of Roux-en-Y gastric bypass (RYGB) patients. Severe cases are refractory to diet and medications. Surgical treatments including bypass reversal and pancreatectomy are highly morbid and hypoglycemia often recurs. We have developed a highly effective method of treatment by which enteral nutrition administered through a gastrostomy (G) tube placed in the remnant stomach replaces oral diet: if done correctly this reverses hyperinsulinemia and hypoglycemia, yielding substantial health and quality of life benefits for severely affected patients.

OBJECTIVES

To provide clinical guidelines for placement of a G-tube to treat postRYGB hypoglycemia, including candidate selection, preoperative evaluation, surgical considerations, and post-RYGB management.

SETTING

Stanford University Hospital and Clinics.

METHODS

Based on our relatively large experience with placing and managing G-tubes for PBH treatment, an interdisciplinary task force developed guidelines for practitioners.

RESULTS

A team approach (endocrinologist, dietitian, surgeon, psychologist) is recommended. Appropriate candidates have a history of RYGB, severe hypoglycemia refractory to medical-nutrition therapy, and significantly affected quality of life. Preoperative requirements include education and expectation setting, determination of initial enteral feeding program, and establishing service with a home enteral provider. Close postoperative follow-up is needed to ensure success and may require adjustments in formula and mode/rate of delivery to optimize tolerance and meet nutritional goals. G-tube nutrition must fully replace oral nutrition to prevent hypoglycemia.

CONCLUSIONS

G-tube placement in the remnant stomach represents a relatively well-tolerated and effective treatment for severe, refractory hypoglycemia after RYGB.

Gastrostomy tube placement: An opportunity for establishing patient-centered goals of care

BACKGROUND

Surgeons and other health care providers are frequently consulted for gastrostomy tube placement in seriously ill patients at risk of outcomes poorly aligned with patient goals. Palliative care assessments have been recommended to guide decision-making in this setting. We aimed to characterize patient-centered outcomes and define the extent of unmet palliative care need in patients receiving gastrostomy tubes.

METHODS

This is a retrospective study of all adult, nontrauma inpatients who underwent gastrostomy tube placement over 16 months at an urban academic medical center. Outcomes included in-hospital and 1-year mortality, functional status at discharge, and receipt of palliative care assessment preprocedure.

RESULTS

Gastrostomy tubes were placed in 205 patients. In-hospital and 1-year mortality rates were 8% and 19%, respectively. Of patients surviving to discharge, 69% were unable to live independently. Among patients with acute brain injury or respiratory failure, 90% died in the hospital or were severely disabled at discharge. Only 12% of patients received a documented palliative care assessment preprocedure.

CONCLUSION

Given high risks of mortality and poor functional outcomes, consideration of gastrostomy tube placement is an appropriate but underutilized trigger for palliative care assessment. This study highlights an untapped opportunity to optimize the goal concordance of treatment in operative intervention.

Occurrence of complications and survival rates in elderly with neurological disorders undergoing enteral nutrition therapy

OBJECTIVE

To evaluate the occurrence of complications, as well as the survival rates, in elderly people having neurological diseases and undergoing enteral nutrition therapy (ENT).

METHODS

Patients aged over 60 years, assisted by a home medical service from a healthcare plan in the city of Belo Horizonte, MG, Brazil, were thoroughly evaluated. The mentioned evaluation occurred at their homes after hospital discharge with enteral nutrition (EN) after a three-month period, a six-month period, and at the end of the study. A nutritional assessment was performed along with data collection performed on the patients' electronic medical records, and interviews performed with patients' family members and caregivers.

RESULTS

Seventy-nine patients aged 82.9 ± 10.4 years old were evaluated; of these, 49.4% presented dementia, and 50.6% presented other neurological diagnoses. 100% of patients presented a high dependence level, assessed by the Katz index. The majority of patients (91.2%) presented some complications such as: pneumonia, catheter loss, diarrhea, constipation, vomiting, fluid leakage, periostotomy, tube obstruction, reflux, and myiasis. Pneumonia was the most frequent complication, occurring in 55.9% of cases. The mortality rates were 15.2% at a three-month period, 22.8% at a six-month period, and 43% at the end of study. The median survival after starting EN was 364 days. Differences among the mortality rate and neurological diagnosis, EN routes of access, and complications were not observed. The survival rate was lower in patients having inadequate nutritional status and albumin levels < 3.5 mg/dL.

CONCLUSION

The population followed presented a high rate of complications and death at the end of the study. Diagnosis of dementia, EN routes of access, as well as complications, did not influence the survival rates. However, inadequate nutritional status according to the clinical assessment and albumin levels lower than 3.5 mg/dL significantly influenced the survival rates.

Managing patients with gastrostomy tubes in the community: can a dedicated enteral feed dietetic service reduce hospital readmissions?

BACKGROUND/OBJECTIVES

Post-gastrostomy complications range from 8 to 30%. These complications often occur following discharge into the community and may result in hospital readmission. Our unit previously reported a readmission rate of 23% in 6 months. There is a paucity of data evaluating community gastrostomy management. We therefore aimed to evaluate the benefits of a dedicated dietetic home enteral feed (HEF) team.

SUBJECTS/METHODS

Demographic data, gastrostomy complications, readmission rates and HEF team input was prospectively collected from a cohort of discharged gastrostomy patients over a 1-year period and comparisons made with a similar historical cohort.

RESULTS

A total of 371 complications were encountered in 313 gastrostomy patients during this period, with the commonest complication being over-granulated stoma sites (27%). Of these, 227 hospital admissions were avoided because of direct actions taken by the HEF team. Fifty-nine gastrostomy patients were admitted to the hospital, of which only seven (12%) were specifically for gastrostomy-related problems. Introduction of the HEF team significantly reduced gastrostomy-related hospital readmissions from 23 to 2% (P = 0.0001).

CONCLUSION

Although patients with gastrostomies may need attention to a variety of complex medical problems, many encounter problems specifically related to their gastrostomy after discharge. This is the largest prospective study demonstrating how dietitians trained in gastrostomy aftercare may optimize the management of gastrostomy complications and reduce unnecessary hospital readmissions.

Efficacy of pectin solution for preventing gastro-esophageal reflux events in patients with percutaneous endoscopic gastrostomy

The aim of this study was to determine the efficacy of pectin solution, which increases the viscosity of liquid nutrient, for prevention of gastro-esophageal reflux in comparison with half-solid nutrient. The subjects were 10 elderly patients undergoing percutaneous endoscopic gastrostomy feeding. Twenty-four-hour esophageal multichannel intraluminal impedance and pH testing was performed during intake of half-solid nutrient and a combination of pectin solution and liquid nutrient. During 4 h after delivery, there was no significant difference in the total number of gastro-esophageal reflux events between the feeding of the half-solid nutrient and the combination of pectin solution and liquid nutrient (5.7 ± 1.2 vs 5.3 ± 1.0/4 h). Acidic reflux after delivery of the half-solid nutrient was significantly more frequent than that after delivery of the combination of pectin solution and liquid nutrient (80.7% vs 60.4%, p = 0.018). The incidence of gastro-esophageal reflux reaching the upper portion of the esophagus tended to be higher during delivery of the half-solid nutrient than during delivery of the combination of pectin solution and liquid nutrient (47.4% vs 34.0%, p = 0.153). In conclusion, the usage of pectin solution combined with liquid nutrient is effective for preventing acidic gastro-esophageal reflux and gastro-esophageal reflux reaching the upper portion of the esophagus.

Percutaneous Endoscopic Gastrostomy Prevents Gastroesophageal Reflux in Patients with Nasogastric Tube Feeding: A Prospective Study with 24-Hour pH Monitoring

Background/Aims

Percutaneous endoscopic gastrostomy (PEG) has been widely used for patients with swallowing dysfunction. However, its beneficial effects in the treatment of gastroesophageal reflux (GER) are controversial. The aim of this study was to evaluate the effect of PEG on the prevention of GER in patients with nasogastric tube (NGT) feeding.

Methods

Continuous 24-hour pH monitoring was performed prospectively in 21 patients receiving NGT feeding before and 7.3±2.2 days after PEG placement to compare the severity of GER.

Results

We studied 21 patients with a mean age of 59.8±14.1 years. The mean duration of NGT placement was 5.8±5.4 months. The causes of swallowing dysfunction included cerebral infarction, cerebral hemorrhage and other central nervous system (CNS) lesions. When all of the patients were considered, there were no significant differences in reflux parameters after PEG placement compared to before PEG placement. However, all seven patients who had preexisting GER showed significant improvement (p<0.05) of the reflux parameters, including the frequency of acid reflux, duration of acid reflux, total time with a pH below 4.0 and the fraction of time with a pH below 4.0, after PEG placement.

Conclusions

PEG might prevent GER in patients receiving NGT feeding, especially in those patients with GER.

Efficacy of half-solid nutrient for the elderly patients with percutaneous endoscopic gastrostomy

Percutaneous endoscopic gastrostomy tube feeding is widely used for patients with swallowing dysfunction and a history of repeated aspiration pneumonitis. However, liquid nutrient feeding via percutaneous endoscopic gastrostomy is not effective enough to prevent aspiration pneumonitis and related inflammatory responses. We performed this prospective multi-centre study to clarify the efficacy of half-solidification of nutrients to prevent fever possibly caused by aspiration pneumonitis in elderly patients with percutaneous endoscopic gastrostomy. The study subjects were 42 elderly patients undergoing percutaneous endoscopic gastrostomy feeding (mean age 85.8 years). All subjects were fed half-solid as well as liquid nutrients for 8 weeks respectively in a cross over design. We counted the number of days with fever caused by pneumonitis and unidentified origin. Thirty-two of 42 patients were successfully observed in both nutrient periods. Fever was frequently observed in both nutrient periods, however, the percentage of observational days with fever during half-solid nutrient feeding was significantly lower than that during liquid nutrient feeding (15.3 ± 0.3 vs 19.8 ± 0.4%, p = 0.030). The percentage of observational days when patients had diarrhea was not significantly different (10.1 ± 3.8 vs 7.2 ± 3.2%, p = 0.357). In conclusion, half-solid nutrient feeding was determined to be effective for reducing fever in patients with percutaneous endoscopic gastrostomy feeding.

Half-solidification of nutrient does not decrease gastro-esophageal reflux events in patients fed via percutaneous endoscopic gastrostomy

BACKGROUND & AIMS

Percutaneous endoscopic gastrostomy (PEG) tube feeding is widely used for patients with swallowing dysfunction, and aspiration pneumonitis induced by reflux of gastric contents is one of the most frequent and life-threatening events in such patients. We performed this study to clarify the effect of half-solidification of nutrient on gastro-esophageal reflux (GER) of acidic and non-acidic gastric contents in patients with PEG.

METHODS

The subjects were 14 elderly patients undergoing PEG feeding (female: 11, mean age 83.1 y). Twenty-four hour esophageal multichannel intraluminal impedance (MII) and pH (MII-pH) monitoring were performed during and after feeding with half-solid and liquid nutrient, respectively. The numbers of GER events during 4h after the start of feeding were compared.

RESULTS

There was no significant difference in the total number of GER events between half-solid nutrient feeding and liquid nutrient feeding (5.6+/-1.5 vs. 6.6+/-1.5). The number of acid reflux events after half-solid nutrient feeding tended to be higher than that after liquid nutrient feeding (1.9+/-1.1 vs. 1.4+/-0.8).

CONCLUSION

Half-solidification of nutrition does not appear to be effective for preventing GER caused by liquid PEG feeding.

Clinical analysis of gastroesophageal reflux after PEG

BACKGROUND

It is difficult to predict whether or not gastroesophageal reflux (GER), such as aspiration or vomiting, will occur after PEG.

OBJECTIVE

To identify factors that would support the prediction of aspiration after PEG.

DESIGN

Case-control study.

SETTING

Patients who underwent PEG from February 1998 to June 2005 in our hospital.

PATIENTS

The study included 178 patients.

INTERVENTIONS

Endoscopic observation was carried out during PEG tube placement and at PEG tube replacement to determine the presence of hiatus hernia and/or reflux esophagitis.

MAIN OUTCOME MEASUREMENTS

Gastric emptying and GER index (GERI) were measured by using a radioisotope technique.

RESULTS

The patients were divided into 2 groups: the non-GER (NGER) group (n = 108), who had no symptoms of GER, and the GER group (n = 70), who showed these symptoms. No significant differences were observed between the groups in age, sex, morbidity, the presence of reflux esophagitis at PEG tube placement, gastric emptying, or serum albumin levels. The presence of a hiatus hernia (P = .028) and reflux esophagitis grading Los Angeles classification C or D (P = .008) were significantly more frequent in the GER group compared with the NGER group. The GERI was also significantly higher in the GER group than in the NGER group (P < .0001).

CONCLUSIONS

The presence of hiatus hernia, severe reflux esophagitis, and a high GERI might be predictive factors of aspiration or vomiting after PEG tube placement.

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.

ESPEN Guidelines on Enteral Nutrition: Geriatrics

Nutritional intake is often compromised in elderly, multimorbid patients. Enteral nutrition (EN) by means of oral nutritional supplements (ONS) and tube feeding (TF) offers the possibility to increase or to insure nutrient intake in case of insufficient oral food intake. The present guideline is intended to give evidence-based recommendations for the use of ONS and TF in geriatric patients. It was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was discussed and accepted in a consensus conference. EN by means of ONS is recommended for geriatric patients at nutritional risk, in case of multimorbidity and frailty, and following orthopaedic-surgical procedures. In elderly people at risk of undernutrition ONS improve nutritional status and reduce mortality. After orthopaedic-surgery ONS reduce unfavourable outcome. TF is clearly indicated in patients with neurologic dysphagia. In contrast, TF is not indicated in final disease states, including final dementia, and in order to facilitate patient care. Altogether, it is strongly recommended not to wait until severe undernutrition has developed, but to start EN therapy early, as soon as a nutritional risk becomes apparent.

Prospective, randomized, controlled, single-blind trial of the costs and consequences of systematic nutrition team follow-up over 12 mo after percutaneous endoscopic gastrostomy

OBJECTIVES

We assessed the economic and clinical implications of systematic long-term nutrition team follow-up of patients after percutaneous endoscopic gastrostomy.

METHODS

We designed a prospective, randomized, controlled, single-blind trial in a large district hospital and its catchment area. All adult patients referred for a gastrostomy were eligible and randomized into two groups. The intervention group had regular follow-up by the nutrition team (weekly in hospital, monthly after discharge) with appropriate support and advice for patient, carer, and primary care professionals. The control group had no specific nutrition team input (as is often current practice). Endpoints to the study were 12 mo, elective removal of tube, or death. The primary outcome was total health care costs. Secondary outcomes were complications, length of stay, readmissions, nutritional status, and quality of life.

RESULTS

One hundred twelve patients were recruited. Eleven died before the start of the trial, leaving 47 in the intervention group and 54 in the control group. They were well matched for age, sex, and underlying diagnosis. Overall, the health care costs were 13,330 sterlings per patient in the intervention group compared with 16,858 pound sterlings in the control group (two-tailed, P = 0.27), a saving of 21% per patient. The intervention group had shorter lengths of stay, fewer and briefer readmissions, earlier removal of gastrostomy (where appropriate), shorter duration of feeding, and less demand for general practitioners and district nurse inputs. Nutritional status and quality of life were similar.

CONCLUSIONS

Regular systematic nutrition team follow-up for gastrostomy-fed patients does not increase costs and may improve quality of care.
