Tube feeding in the elderly

Impact of choice of feeding tubes on long-term swallow function following chemoradiotherapy for oropharyngeal carcinoma

Background: Prior reports have raised concerns that a prophylactic gastrostomy may be detrimental to long-term swallow function. This study evaluates patient-reported swallow function following chemoradiotherapy for oropharyngeal carcinoma in relation to the use of a prophylactic gastrostomy or nasogastric (NG) tube as required. Material and methods: The MD Anderson Dysphagia Inventory (MDADI) was posted to 204 disease-free patients at least 2 years following chemoradiotherapy for oropharyngeal carcinoma between 2010 and 2014. Results: Overall, 181/204 (89%) patients returned questionnaire at a median of 34 months post-treatment. 97/181 (54%) and 84/181 (46%) were managed with an approach of a prophylactic gastrostomy or NG tube as required, respectively. A prophylactic gastrostomy was associated with higher rates of enteral feeding (92% vs. 58%, p < .001), lower median percentage weight loss (7.0% vs. 9.4%, p < .001), increased duration of enteral feed (median 3.3 vs. 1.1 months, p < .001). There was no significant difference in patient-reported swallow function measured by MDADI summary scores and subscales for patients managed with an approach of prophylactic gastrostomy or NG as required. Duration of enteral feed correlated negatively with composite MDADI scores. A subgroup of 116/181 (64%) patients were documented as having been offered a choice of enteral feeding approach and therefore can be considered to represent clinical equipoise; there were no significant differences in MDADI scores according to route. Conclusions: Despite concern regarding the use of a prophylactic gastrostomy in prior studies, the approaches of using a prophylactic gastrostomy or an NG tube as required to support patients during/after chemoradiotherapy for oropharyngeal carcinoma were associated with similar long-term swallow outcomes.

Effect of an indwelling nasogastric tube on swallowing function in elderly post-stroke dysphagia patients with long-term nasal feeding

BACKGROUND

In clinical practice, a large number of post-stroke survivors require nasogastric tube (NGT) placement and nasal feeding for a relatively long period. However, its impact on the swallowing function remains largely unknown. This study examines the impact of prolonged placement of an NGT on the swallowing function of elderly post-stroke patients.

METHODS

The participants of this study were 30 elderly post-stroke patients who had been using an NGT for more than 2 months. A videofluoroscopic swallowing study (VFSS) was performed before and 5 h after removal of the NGT. The following parameters were analyzed and compared, the functional dysphagia scale (FDS), residue in the valleculae, residue in the pyriform sinuses, and the penetration-aspiration scale (PAS). In addition, prior to the VFSS, the pharynx and larynx were examined using a fiberoptic laryngoscope.

RESULTS

Significant differences were observed between the total scores of the FDS, pharyngeal transit times (PTTs), the residue in the valleculae, and the residue in the pyriform sinuses before and after the NGT removal, suggesting an improved swallowing function following the removal of the NGT. A significantly lower penetration-aspiration degree was found after removing the NGT compared with that before its removal. In addition, examinations using the fiberoptic laryngoscope showed that laryngopharyngeal edema was present in three quarters of the patients.

CONCLUSIONS

Our results demonstrate that prolonged placement of the NGT had a negative impact on the swallowing function of elderly post-stroke dysphagia patients, mainly on the pharyngeal phase.

Effect of Presence/Absence of a Nasogastric Tube in the Same Person on Incidence of Aspiration

Objective. To determine what effect, if any, the presence or absence of a nasogastric (NG) tube in the same person had on the incidence of anterograde aspiration.

Design. Case series with planned data collection.

Setting. Large, urban, tertiary care teaching hospital.

Subjects and Methods. Referred sample of 62 consecutively enrolled adult inpatients for fiber-optic endoscopic evaluation of swallowing (FEES). Group 1 (n = 21) had either small-bore (n = 13) or large-bore (n = 8) NG tubes already in place and had a FEES first with the NG tube in place and a second FEES after NG tube removal. Group 2 (n = 41) did not have an NG tube and had a FEES first without an NG tube and a second FEES after placement of a small-bore NG tube. Time between FEES was approximately 5 minutes. Patients were tested with thin liquid and puree food consistencies. Occurrence of aspiration for each consistency dependent on the presence or absence of an NG tube was recorded.

Results. There were no significant differences ( P > .05) in aspiration status for both liquid and puree consistencies in the same person dependent on presence or absence of either a small-bore or large-bore NG tube.

Conclusions. Since objective swallowing evaluation (eg, FEES) can be performed with an NG tube in place, it is not necessary to remove an NG tube to evaluate for aspiration. Similarly, there is no contraindication to leaving an NG tube in place to supplement oral alimentation until nutritional requirements are achieved.

A survey of the reasons patients do not chose percutaneous endoscopic gastrostomy/jejunostomy (PEG/PEJ) as a route for long-term feeding

AIMS

To investigate why patients do not choose percutaneous endoscopic gastrostomy or percutaneous endoscopic jejunostomy as a route for long-term feeding.

BACKGROUND

Home enteral tube feeding is well recognised as a valuable therapeutic option for patients requiring nutritional support following discharge from hospital. The number of patients discharged from hospital and receiving home enteral tube feeding increases annually in Taiwan.

DESIGN

A cross-sectional study.

METHOD

Participants (n = 607) were chosen from one free-standing home care agency and three hospital-based home care departments in Taipei. A review of the patients' records to gather demographic data, medical diagnosis, length of home care and length of intubation prior to the home visit was conducted. A face-to-face interview was conducted at the time of the home visit.

FINDINGS

The prevalence rate of home enteral tube feeding was 70.3% (n = 427). Of the 427 tube-fed subjects, 93.4% were fed with a nasogastric tube. The most common reasons for refusing to use percutaneous endoscopic gastrostomy or percutaneous endoscopic jejunostomy were 'too old to suffer from an operation', 'worried about wound infection or leakage after performing percutaneous endoscopic gastrostomy' and 'to keep subjects' body integrity'. Stroke, no dementia, poor activities of daily living and poor cognitive status were significant predictors of being tube-fed, while higher education and better cognitive status were significant predictors of percutaneous endoscopic gastrostomy or percutaneous endoscopic jejunostomy use.

CONCLUSION

The reasons patients refused to use percutaneous endoscopic gastrostomy or percutaneous endoscopic jejunostomy reflect the influence of cultural values and the level of patients' education, which home health care nurses need to discuss with patients in detail.

RELEVANCE TO CLINICAL PRACTICE

Investigating patients' perspective on the meaning of 'body' in Taiwanese culture and the decision-making processes related to home enteral tube feeding is recommended for nurses to provide better care and support when home enteral tube feeding in an option.

Effectiveness of end-of-life education among community-dwelling older adults

The purpose of this study was to evaluate the effectiveness of an educational intervention regarding end-of-life discussion directed at older Japanese adults and their attitude to and acceptance of this intervention. A quasi-experimental design was used. A total of 121 older adults, aged 65 years and over, consented to participate. Data from 55 intervention and 57 control participants were used for the analysis. The intervention consisted of an education program comprising a video, a lecture using a handout, and discussion among participants. The control group received only the handout. Both groups were followed up after one month. The intervention group’s attitude became more favorable towards advance directives, especially living wills (P = 0.024). In addition, their expression of preference for life-sustaining treatment by means of artificial nutrition was less at follow up, demonstrating that these older adults had become more autonomous (P = 0.008). There was greater acceptance of the intervention as a whole by the intervention group compared with the control group (P = 0.011). Although few participants overall completed living wills, at follow up twice as many in the intervention group had discussed end-of-life matters with family members and/or their physician.

[Approach to dysphagia in advanced dementia]

From the onset, dementia affects the patient's nutritional status, producing anorexia, weight loss, feeding apraxia and dysphagia. Distinct strategies are required in each of the stages of this disease, starting with awareness and knowledge of the problem and its prompt detection. In dementia, dysphagia usually appears in advanced phases, when the patient is often institutionalized. When dysphagia is suspected, the patient's tolerance must be evaluated by the volume/viscosity test, environmental and postural strategies should be introduced, and the texture of the diet should be modified. This is a complex task requiring the involvement of a properly trained interdisciplinary team, able to provide information and alternatives and integrate the family environment in the patient's care. The adapted diet should be based on the traditional diet that can also be combined with artificial supplements to provide a varied diet that increases patients', caregivers' and relatives' satisfaction. Tube feeding has shown no nutritional benefits in patients with advanced dementia. Therefore, we propose assisted oral feeding as the most natural and appropriate form of feeding in these patients, always respecting their previously expressed wishes.

Complications of percutaneous endoscopic and fluoroscopic gastrostomy tube insertion procedures in 378 patients

Gastrostomy tubes are used for primary and supplemental feeding and gastric decompression. The purpose of the study was to compare the complication rate of gastrostomy tube placement by either endoscopic or fluoroscopic technique. Between 1996 and 2004, the surgical and radiological services at a Level I trauma hospital placed gastrostomy tubes in 378 patients (endoscopy=268, fluoroscopy=110). The percutaneous gastrostomy group comprised 71% of the cohort with a mean age of 51+/-21 (range: 1-93 years of age), and the percutaneous radiographic gastrostomy group comprised the remaining cohort (29%) with a mean age of 57+/-19 (range: 17-95 years of age). Fifty-eight percent of the percutaneous gastrostomy group were female (n=155) and 42% were male (n=113), whereas the gender distribution for the percutaneous radiographic gastrostomy group was 33% female (n=36) and 67% male (n=74). There was an overall complication rate of 36% (22% and 70% for the endoscopic and fluoroscopic methods, respectively). The most frequent complication in both types of techniques was tube dislodgement (endoscopic=32% [19/268]; fluoroscopic=27% [21/110]). There were very few serious complications. Women had a higher rate of postprocedure complications than did men, at 35% versus 27%. We conclude that gastrostomy tube placement by either endoscopic or fluoroscopic methods results in a number of complications, though most of them are minor. Patients must therefore be informed that this is not a complication-free procedure.

Dysphagia: implications for older people

This review opens with an outline definition of dysphagia, its causes, and why it is vital that people involved in the health care of older people should be aware of it. A brief consideration of prevalence is followed by an overview of assessment options. We conclude with a section on management.

The effect of nasogastric tubes on swallowing function in persons with dysphagia following stroke

OBJECTIVE

To determine whether the use of a nasogastric tube influences swallowing function in stroke patients with dysphagia.

DESIGN

Before-after trial.

SETTING

Primary care center.

PARTICIPANTS

A total of 22 patients with stroke (12 men, 10 women; mean age, 69.7 y; range, 19-85 y) participated in the study. Time from onset of stroke to time of assessment averaged 20.3 days (range, 14-38 d). All participants continued to use a nasogastric tube for nutrition supply and had either minor or no aspiration of barium on videofluoroscopic examination of swallowing (VFES).

INTERVENTION

The swallowing function was evaluated by VFES with thin and thick bariums (5 mL each) as a contrast medium.

MAIN OUTCOME MEASURES

The oral transit, swallowing trigger, and pharyngeal transit times were measured and compared before and after the removal of the nasogastric tube. The patients were also observed for changes in velopharyngeal closure, pharyngeal contraction, epiglottic tilt, valleculae stasis, pyriform sinus stasis, penetration, and aspiration.

RESULTS

Transit times were reduced by 0.2 to 0.6 seconds after removal of the nasogastric tube, but the reduction was not statistically significant. These transit times were slightly longer with thick barium than with thin barium, but were without statistical significance. Similarly, most of the patients had no change in nontemporal assessment of swallowing function after the tube was removed.

CONCLUSIONS

The placement of a nasogastric tube did not affect temporal and nontemporal measurement of swallowing in stroke patients with dysphagia with or without minor aspiration.
