Outcomes of feeding problems in advanced dementia in a nursing home population

Abstract

Objectives: To describe quality of care for feeding problems in advanced dementia and probability and predictors of weight loss and mortality.

Design: Prospective cohort.

Setting: Twenty-four nursing homes (NHs).

Participants: Nursing home residents with advanced dementia and feeding problems and family surrogates (N = 256).

Measurements: Family reported on quality of feeding care at enrollment and 3 months. Chart reviews at enrollment and 3, 6, and 9 months provided data on feeding problems, treatments, weight loss of more than 5% in 30 days or more than 10% in 6 months, and mortality. Organizational variables were obtained from administrator surveys and publically reported data.

Results: Residents with advanced dementia and feeding problems had an average age of 85; 80% had chewing and swallowing problems, 11% weight loss, and 48% poor intake. Family reported feeding assistance of moderate quality; 23% felt the resident received less assistance than needed. Mortality risk was significant; 8% died within 3 months, 17% within 6 months, and 27% within 9 months. Residents with advanced dementia who had stable weight over 3 months had a 5.4% rate of significant weight loss and a 2.1% risk of death over the next 3 months. Residents with advanced dementia and weight loss over 3 months had a 38.9% chance of stabilizing weight over the next 3 months but also had a 19.2% chance of dying. Weight loss was the only independent predictor of death.

Conclusion: Weight loss is a predictor of death in advanced dementia. Treatments can often stabilize weight, but weight loss should be used to trigger discussion of goals of care and treatment options.

Three Month Outcome Probabilities for Advanced Dementia with Feeding Problems A resident with advanced dementia and stable weight has a 5.4% chance of developing weight loss over the next 3 months, and a 2.1% chance of dying during that time interval. A resident with advanced dementia and weight loss has a 38.9% chance of stabilizing weight over the next 3 months, and a 19.2% chance of dying during that same time interval.
