Abstract
BACKGROUND: A simple and predictable method of evaluating eating and swallowing has not been yet established; thus, it is difficult to implement advance care planning according to deterioration in this function. This study aimed to clarify the association between a simple evaluation of eating and swallowing function and 1-year mortality in advanced dementia patients in nursing homes in Japan. METHODS: The study included 325 residents with advanced dementia. In a baseline survey, we examined medical history, physical function, and eating and swallowing function. We recorded mortality for 1 year from baseline. Kaplan-Meier survival analysis and Cox proportional regression were performed to investigate the association between the simple evaluation of eating and swallowing function and mortality. RESULTS: Statistical analysis included data from 312 of the 325 residents who had completed the baseline survey (7 individuals with non-oral ingestion and 6 who were alive but did not reside in the nursing home 1 year later were excluded). The participants' mean age was 85.2 years, and 79.5 % of participants were female. At the 1-year follow-up, 70 patients had died. According to Cox proportional regression analysis, age, male gender, history of cerebrovascular disorder, poor results of palpation of masseter muscle tension, and modified water swallowing test were significantly associated with 1-year mortality. CONCLUSION: The results of palpation of masseter muscle tension and modified water swallowing test were associated with 1-year mortality. These routine observations can predict mortality, and may thus provide evidence of the opportunity to implement advance care planning.
