Background: Difficulty with oral feeding, the most commonly observed complication of Alzheimer disease (AD) in its final stages, occurs in 86% of AD patients and may prevent achievement of oral feeding after aspiration pneumonia. However, no reliable indicators of discontinuance of oral feeding have yet been identified. We therefore aimed to identify predictors of discontinuance of oral feeding in postaspiration pneumonia patients with AD.

Materials and Methods: Relevant clinical and laboratory data of 60 patients with AD admitted to our hospital in Japan for aspiration pneumonia were retrospectively compared between oral feeding and discontinuance groups.

Results: The study groups differed in interval since diagnosis of AD, CURB-65 score, pneumonia severity index score, and proportion of patients who died (higher in the discontinuance group) and body mass index (BMI), Mini Mental State Examination (MMSE) score, and functional independence measure score (lower in the discontinuance group). According to multivariate logistic regression analysis of all identified independent variables, only CURB-65 and MMSE scores and BMI are significant predictors of discontinuance of oral feeding after aspiration pneumonia in patients with advanced AD.

Conclusions: In patients with advanced AD, discontinuance of oral feeding after aspiration pneumonia may be predicted by CURB-65 and MMSE scores and BMI.
