The provision of artificial enteral nutrition to an aged person with severe cognitive impairment is a complex dilemma in the long-term care setting.
                To determine the risk factors and impact on survival of feeding tubes in nursing home residents with advanced cognitive impairment.
                We conducted a cohort study with 24-month follow-up using Minimum Data Set resident assessments on 1386 nursing home residents older than 65 years with recent progression to severe cognitive impairment in the state of Washington. Residents within this population who underwent feeding tube placement were identified. Clinical characteristics and survival for a period of 24 months were compared for residents who were and were not tube fed.
                Among the residents with recent progression to severe cognitive impairment, 9.7% underwent placement of a feeding tube. Factors independently associated with feeding tube placement included age younger than 87 years (odds ratio [OR], 1.85; 95% confidence interval [CI], 1.25-2.78), aspiration (OR, 5.46; 95% CI, 2.66-11.20), swallowing problems (OR, 3.00; 95% CI, 1.81-4.97), pressure ulcer (OR, 1.64; 95% CI, 1.23-2.95), stroke (OR, 2.12; 95% CI, 1.17-2.62), less baseline functional impairment (OR, 2.07; 95% CI, 1.27-3.36), no do-not-resuscitate order (OR, 3.03; 95% CI, 1.92-4.85), and no dementia (OR, 2.17; 95% CI, 1.43-3.22). Survival did not differ between groups of residents with and without feeding tubes even after adjusting for independent risk factors for feeding tube placement.
                There are specific risk factors associated with feeding tube placement in nursing home residents with severe cognitive impairment. However, there is no survival benefit compared with similar residents who are not tube fed. These prognostic data are important for health care providers, families, and patients making decisions regarding enteral nutritional support in long-term care. Undernutrition is common in patients admitted with stroke. We aimed to establish whether the timing and route of enteral tube feeding after stroke affected patients' outcomes at 6 months.
                The FOOD trials consist of three pragmatic multicentre randomised controlled trials, two of which included dysphagic stroke patients. In one trial, patients enrolled within 7 days of admission were randomly allocated to early enteral tube feeding or no tube feeding for more than 7 days (early versus avoid). In the other, patients were allocated percutaneous endoscopic gastrostomy (PEG) or nasogastric feeding. The primary outcome was death or poor outcome at 6 months. Analysis was by intention to treat.
                Between Nov 1, 1996, and July 31, 2003, 859 patients were enrolled by 83 hospitals in 15 countries into the early versus avoid trial. Early tube feeding was associated with an absolute reduction in risk of death of 5.8% (95% CI -0.8 to 12.5, p=0.09) and a reduction in death or poor outcome of 1.2% (-4.2 to 6.6, p=0.7). In the PEG versus nasogastric tube trial, 321 patients were enrolled by 47 hospitals in 11 countries. PEG feeding was associated with an absolute increase in risk of death of 1.0% (-10.0 to 11.9, p=0.9) and an increased risk of death or poor outcome of 7.8% (0.0 to 15.5, p=0.05).
                Early tube feeding might reduce case fatality, but at the expense of increasing the proportion surviving with poor outcome. Our data do not support a policy of early initiation of PEG feeding in dysphagic stroke patients. Despite the ongoing debate on tube feeding of severely demented patients, the current approach in western countries is to avoid feeding by tube.
                To assess the clinical course and outcome of demented elderly patients with severe disabilities, by feeding mode.
                The study was conducted in a skilled nursing department of a major psychogeriatric hospital in Israel. Eighty-eight patients aged 79 +/- 9 years were followed for 17 months: 62 were fed by nasogastric tube and 26 were orally fed. The groups were compared for background characteristics, underlying medical condition, functional impairment, clinical and nutritional outcomes, and survival.
                Tube feeding had no beneficial effect on clinical and nutritional outcomes or on healing preexisting pressure ulcers, compared with oral feeding. Very few patients on tube feeding showed signs of discomfort, partly because of low cognitive function. Survival was significantly higher in the tube-fed patients (P < 0.001), which could be partly explain by the different case mix (i.e., the underlying diseases)
                Tube feeding seems to have no nutritional advantage in severely demented elderly patients. Median survival was longer in tube-fed individuals who had no acute co-morbidity. However, since tube feeding does not add to patient pain and discomfort, it should not be contraindicated when it complies with the values and wishes of patients and their families. The influence of tube feeding on survival in hospitalized patients with advanced dementia is controversial.
                To assess long-term survival in an inception cohort, incident tube feeding placement during the index hospitalization, and the influence of tube feeding on survival in this group of patients.
                Ninety-nine hospitalized patients with advanced dementia and an available surrogate decision maker were followed up through and after the index hospitalization for mortality and placement of a feeding tube. Other variables measured included advance directive status, presence of a long-term primary care physician, level of involvement of the surrogate decision maker, admitting diagnosis, prior hospitalizations, comorbidities, and diagnosis related group diagnostic category.
                A new feeding tube was placed in 50% (51/99) of the study patients during the index hospitalization, 31% (31/99) left the hospital without a feeding tube, and 17% (17/99) were admitted with a feeding tube already in place. By stepwise logistic regression analysis, predictors of new feeding tube placement included African American ethnicity (odds ratio, 9.43; 95% confidence interval, 2.1-43.2) and residence in a nursing home (odds ratio, 4.9; 95% confidence interval, 1.02-2.5). Median survival of the 99 patients was 175 days. Eighty-five (85%) survived the index hospitalization, and 28 (28%) were still alive at last follow-up, a range of 1.3 to 4.2 years after enrollment in the study. Tube feeding was not associated with survival (P =.90). An admitting diagnosis of infection was associated with higher mortality (odds ratio, 1.9; 95% confidence interval, 1.01-3.6).
                In this cohort of hospitalized patients with advanced dementia, risk of receiving a new feeding tube is high, associated with African American ethnicity, and prior residence in a nursing home, and has no measurable influence on survival. With or without a feeding tube, these patients have a 50% six-month median mortality. Artificial feeding by a percutaneous endoscopic gastrostomy (PEG) tube in patients with dementia has increased since the introduction of the endoscopic method of tube placement. Few studies have documented survival benefit from this intervention. This report reviews our experience with PEG tube placement for feeding patients with dementia.
                All consultations for PEG tube placement were evaluated by a certified nutrition support nurse (L.M.M.) in consultation with a member of the gastroenterology physician staff (T.O.L.) for 24 months. Evaluation included the attainment of a brief medical history, a physical examination, and a review of comorbid conditions, laboratory variables for nutrition status, and bleeding risk. Interviews with patients or surrogates were conducted, including an explanation of the risks and benefits of PEG tube placement. A Kaplan-Meier survival curve was used to compare the median survival between patients with dementia who received a PEG tube and patients with dementia in whom PEG tube placement was refused.
                We received 41 consultations for PEG tube placement in patients with dementia. Percutaneous endoscopic gastrostomy was performed in 23 patients; 18 patients met the medical criteria for PEG tube placement, but surrogates refused placement. The median survival for the 23 patients who underwent PEG was 59 days; the median survival for the 18 patients who did not undergo PEG was 60 days.
                There seems to be no survival benefit in patients with dementia who receive artificial feeding by a PEG tube. The terminal phase of dementia is initiated by the inability to swallow. New techniques of enteral alimentation permit more effective, longer intubation. To assess the application of these new techniques to late-stage demented aged patients, all current intubations in a teaching nursing home were reviewed. Of 52 feeding intubations, 26 had been in situ for more than 1 year. A randomly selected comparison group of nonintubated patients was also studied. Weight increased for 48% of the intubated group versus 17% of the nonintubated group (P less than .01). Aspiration pneumonia occurred more often in the intubated group (58%) than in the nonintubated group (17%) (P less than .01). Decubitus ulcers were also more common in the intubated group (21%) than in the nonintubated group (14%). Restraints were used more in the intubated group (71%) than in the nonintubated group (56%). These differences did not reach statistical significance. All of the intubated patients were severely demented, with MMSE scores of zero. Seventy-one percent of the nonintubated group were demented, with MMSE scores of less than 23. Prolongation of the terminal phase of dementia in the aged by tube feeding is now feasible. The implications of this change in the life-span of demented nursing home patients need attention by families, nursing homes, and those who make public health policy. To compare percutaneous endoscopic gastrostomy and nasogastric tube feeding in patients with persisting neurological dysphagia.
                Randomised 28 day study of inpatients requiring long term enteral nutrition.
                Three Glasgow teaching hospitals.
                40 patients with dysphagia for at least four weeks secondary to neurological disorders: 20 patients (10 women) were randomised to nasogastric feeding and 20 (eight women) to endoscopic gastrostomy.
                Treatment failure (blocked or displaced tubes on three or more occasions or refusal to continue treatment); duration of feeding; intake of liquid diets; complications; nutritional status at end of trial.
                One patient in each group died before starting feeding. Treatment failure occurred in 18 of the 19 nasogastric patients and in none of the gastrostomy group. The mean (SE) duration of feeding for the nasogastric group was 5.2 (1.5) days. No complications occurred in the nasogastric group but three (16%) of the gastrostomy group developed minor problems (aspiration pneumonia (two patients) wound infection (one)). Gastrostomy patients received a significantly greater proportion of their prescribed feed (93% (2%)) compared with the nasogastric group, (55% (4%); p less than 0.001) and also gained significantly more weight after seven days of feeding (1.4 (0.5) kg v 0.6 (0.1) kg; p less than 0.05). Analyses at days 14, 21, and 28 were not possible due to the small numbers remaining in the nasogastric group.
                Percutaneous endoscopic gastrostomy tube feeding is a safe and effective method of providing long term enteral nutrition to patients with neurological dysphagia and offers important advantages over nasogastric tube feeding. The practicality, effectiveness, and safety of feeding very low birthweight infants (less than 1,300 gm) by continuous nasoduodenal infusion was assessed by comparison with continuous nasogastric feeding. The nasoduodenal group appeared to have a clear advantage over the nasogastric group for the overall period in terms of caloric intake (131 cal/kg/day vs. 106 cal/kg/day), average weight gain (16 gm/day vs. 10 gm/day), and safety. This advantage was even more striking in the first two weeks of life. A caloric intake of 120 cal/kg/day could be reached within 48 to 72 hours after tube placement in the nasoduodenal group but only after a week in the nasogastric group. Nasoduodenal feeding resulted in faster weight gain than comparable published data on conventional feeding, peripheral intravenous alimentation, and parenteral alimentation. There were no cases of aspiration associated with tubes placed in the duodenum whereas two cases of aspiration pneumonia were associated with tubes placed in the stomach. With the tip of the catheter in the duodenum, none of the complications reported with nasojejunal tubes (intussusception, perforation, or necrotizing enterocolitis) were seen, either in the initial pilot study reported here or in 50 additional infants. The purpose of the study was to determine whether early postoperative enteral feeding with an immune-enhancing formula (IEF) decreases morbidity, mortality, and length of hospital stay in patients with upper gastrointestinal (GI) cancer.
                Early enteral feeding with an IEF has been associated with improved outcome in trauma and critical care patients. Evaluable data documenting reduced complications after major upper GI surgery for malignancy with early enteral feeding are limited.
                Between March 1994 and August 1996, 195 patients with a preoperative diagnosis of esophageal (n = 23), gastric (n = 75), peripancreatic (n = 86), or bile duct (n = 11) cancer underwent resection and were randomized to IEF via jejunostomy tube or control (CNTL). Tube feedings were supplemented with arginine, RNA, and omega-3 fatty acids, begun on postoperative 1, and advanced to a goal of 25 kcal/kg per day. The CNTL involved intravenous crystalloid solutions. Statistical analysis was by t test, chi square, or logistic regression.
                Patient demographics, nutritional status, and operative factors were similar between the groups. Caloric intake was 61% and 22% of goal for the IEF and CNTL groups, respectively. The IEF group received significantly more protein, carbohydrate, lipids and immune-enhancing nutrients than did the CNTL group. There were no significant differences in the number of minor, major, or infectious wound complications between the groups. There was one bowel necrosis associated with IEF requiring reoperation. Hospital mortality was 2.5% and median length of hospital stay was 11 days, which was not different between the groups.
                Early enteral feeding with an IEF was not beneficial and should not be used in a routine fashion after surgery for upper GI malignancies.
Despite the very large number of patients receiving this intervention, there is insufficient evidence to suggest that enteral tube feeding is beneficial in patients with advanced dementia. Data are lacking on the adverse effects of this intervention.
