A recent review in the Journal of Aging Research highlights the ongoing debate about feeding tube use in individuals with advanced dementia. After evaluating over 400 studies published between 2000 and 2019, the authors found that tube feeding often does not improve survival, nutritional status, or prevent complications like pressure sores or aspiration pneumonia.
Common Beliefs About Tube Feeding
I’ve worked in older adult care for my entire career, outside of a few other clinical opportunities. The most common question when it comes to end of life is can we add a tube feed so they don’t suffer?
This is such a sensitive topic and I like to lean towards a compassionate but informative approach. Read our article on end of life to learn how to have these conversations. Click here to read it.
Despite common beliefs among patients and their loved ones, the data shows tube feeding does not extend life. One study of nearly 36,500 nursing home residents found no survival benefit with PEG placement.
In fact, mortality was higher in some cases, with 30-day death rates reaching 20–40%. Other studies linked tube feeding with increased aspiration risk, hospital admissions, and frequent emergency room visits for tube complications.
Does Tube Feeding Help?
Families often hope tube feeding will ease suffering. But evidence shows it can increase the need for restraints, sedation, and even cause fluid overload or refeeding syndrome. Many patients also lose the social and sensory experience of eating, which hand feeding preserves.
It can also increase bloating, stomach distention, increased discomfort, and make the digestive system work, when it is in fact slowly shutting down.
Still, not all findings were one-sided. A few studies suggest PEG feeding may reduce aspiration compared to NG tubes and improve certain lab markers like albumin. However, these outcomes were not consistently linked to better survival or quality of life.
Wrapping It Up
The take-home: current evidence supports careful hand feeding as the preferred approach for patients with advanced dementia. Feeding tube placement should be a case-by-case decision made by an interdisciplinary team with the family, and grounded in the patient’s goals and values.
More high-quality studies are needed to clarify when, if ever, feeding tubes improve outcomes in this population. As a practicing Dietitian though, I do not recommend overall tube feeding in advanced dementia or at end of life.
If you read our article on end of life (click here to see it), you can see how very difficult decisions can arise if a tube feed is implemented. But at the end of the day, the decision is up to the loved ones.
