Expectations and outcomes of gastric feeding tubes

To compare expected outcomes with actual outcomes from tube feeding in adult patients.

This prospective cohort study was conducted in two North Carolina hospitals. Surrogates were interviewed shortly after feeding tube insertion and at 3- and 6-month follow-up; chart abstraction and death certificate review also were carried out. Participants were surrogate decision-makers for consecutive adult patients who received new feeding tubes.

There were 288 patients with surrogate decision-makers enrolled. Mean age was 65 years; 30% had a primary diagnosis of stroke, 16% neurodegenerative disorder, 20% head and neck cancer, and 30% other diagnoses. At 3 months, 21% of patients had died, and 6-month mortality was 30%. At 3 months, 38% of survivors were residing in a nursing home, and 27% had the feeding tube removed. Patients were impaired in most activities of daily living (ADLs) with little change over time. Medical complications were common: 25% of patients had decubitus ulcers at 3 months, and 24% had at least one episode of pneumonia. Perceived global quality of life was poor at 4.6 (on a 0-10 scale) at baseline, and surrogates anticipated this would improve to 8.0 with tube feeding. Family surrogates' expectations for improvement from the feeding tube were very high at baseline and remained so at 3 and 6 months.

Families' high expectations of benefit from tube feeding are in contrast to clinical outcomes. Providers and families need better information about the outcomes of this common procedure.
