A new study suggests that previous beliefs regarding certain dementia patients’ use of feeding tubes are incorrect. Feeding tubes, the belief went, could rectify nutritional imbalances and therefore aid in the healing of pressure ulcers, also known as bedsores. Research has generally been inconclusive, but this new study appears to disprove the premise entirely.
Patients reviewed in the study who had bedsores when receiving the feeding tube showed no improvement, and patients who previously lacked bedsores before were more likely to develop them with the feeding tube. The study’s conclusions are important to nursing home residents, their families and loved ones, and those who advocate for their safety.
The study looked at hospital records for patients with advanced cognitive impairment, commonly known as dementia, who had a percutaneous endoscopic gastrostomy (PEG) tube inserted, and were then returned to the nursing homes where they live. The purpose of the feeding tube is often to correct nutritional imbalances in the patients, who may suffer from eating disorders brought on by dementia. The study’s lead author has also said that nursing homes and hospitals, looking to cut expenses where possible, may view feeding tubes as a good investment, even if they are not strictly medically necessary. Using feeding tubes in residents suffering from dementia frees up staff members who might otherwise have had to feed those residents by hand.
The study’s findings indicate that not only does the use of feeding tubes not improve a patient’s recovery from bedsores, but that these devices may actually put patients more at risk for having bedsores. Nursing home residents who had no bedsores upon arriving at the hospital were 2.27 times more likely to get a bedsore after getting the feeding tube. Among residents who already had bedsores when they received their feeding tube, researchers found that the bedsores were less likely to heal.
