Patients With Advanced Dementia More Likely to Receive Feeding Tube at Larger, For-Profit Hospitals

Despite being of questionable benefit for patients with advanced dementia, new research finds that hospitals with certain characteristics, such as those that are larger or for-profit, are more likely to have a higher rate of feeding tube placement, according to a study in The Journal of the American Medical Association.

"The decision to place a feeding tube in a patient with advanced dementia is one of the sentinel decisions that family members and healthcare professionals grapple with in the nursing home environment. Two widely cited structured literature reviews conclude that the use of feeding tubes in patients with advanced dementia does not improve survival, prevent aspiration pneumonia, heal or prevent decubitus ulcers, or improve other clinical outcomes,” the authors wrote.

Despite this evidence, a previous study reported that more than one third of nursing home residents with advanced dementia have a feeding tube inserted, and other research has indicated that many of these patients had their feeding tube inserted during an acute care hospitalization, according to the article.

Joan M. Teno, MD, MS, of Brown University, Providence, R.I., and colleagues examined the characteristics of acute care hospitals associated with greater rates of feeding tube insertion among nursing home residents aged 66 or older admitted with advanced cognitive impairment. Rate of feeding tube placement was based on a 20% sample of all Medicare Claims files and was assessed in hospitals with at least 30 such admissions between 2000 and 2007, which was 2,797 acute care hospitals for this study.

During the study period, 280,869 admissions occurred among 163,022 nursing home residents (average age of 84; 67% women and 12.5% black). Between 2000 and 2007, the hospital rate of feeding tube insertion per 100 eligible admissions decreased, from a high of 7.9 in 2000 to a low of 6.2 in 2007. The rate of feeding tube insertion varied from 0 to 38.9 per 100 hospitalizations.

A higher rate of feeding tube insertions was independently associated with for-profit ownership vs. hospitals owned by state or local government, with an absolute difference of three feeding tube insertions per 100 admissions. Hospitals with a greater number of beds (more than 310 beds vs. less than 101 beds) also had higher rates of feeding tube insertion, as did those with more intensive care unit use for chronically ill patients in the last six months of life.

“Feeding tube insertion in persons with advanced cognitive impairment demonstrates a disconnect with the existing evidence of their effectiveness,” the authors wrote.
