摘要

Objectives: Cases related to complaints about memory decline from elderly patients are fairly common in clinical settings, though most of the cases fail to meet the criteria of dementia. Our study aims to understand the correlation between subjective memory impairment (SMI) and functional impairment among elderly people.Method: The sample comprises 1031 hospitalized patients receiving comprehensive geriatric assessments (CGA) in 12 community hospitals between January 2006 and June 2007. Patients who were younger than 65 year old, hospitalized for less than 2 days or over 30 days, could not be reached during follow-ups in one year after discharge, or failed to complete the SMI information, were excluded.Results: A total of 728 patients were recruited. 52.2% of the individuals reported SMI. SMI was correlated with higher mortality rate. Individuals with SMI had higher rates in depression and problems with communication and ambulation. Single variable analysis also found them scoring lower in mini-mental state examination (MMSE), geriatric depression scale (GDS-15), mini-nutritional assessment (MNA), activities of daily living (ADL), and instrumental activities of daily living (IADL). Furthermore, more individuals with SMI were classified as having abnormal MMSE results after stratifying MMSE scores by education.Conclusions: SMI appeared to be prevalent in the elderly patients admitted to community hospitals. They had higher rates of functional decline, lower scores in functional assessments, and higher mortality rates. As indicated by the results, elderly patients complaining about memory impairment are in an urgent need of comprehensive evaluation.
