Demographic characteristics and clinical benefits of outpatient geriatric evaluation and management service in Taiwan.

As Taiwan has become the fastest aging country in the world, developing elderly-friendly health care services is of great importance. Compared with traditional health-care service models, healthcare needs of older people may differ extensively. It has been reported that geriatric evaluation and management (GEM), helps to differentiate the atypical presentations of frail older patients, to discover hidden health-social problems, and to promote long-term clinical outcome. The main purpose of this study was to explore the demographic characteristics of older patients visiting outpatient GEM service and its impact to health-care utilization in a tertiary medical center in Taiwan. From January to October of 2008, 1054 patients visited the outpatient GEM service, and comprehensive geriatric assessment was performed for 140 patients (62.9% males with the mean age was 81.0 ± 6.6 years), and 34.8% of them were college graduates. Overall, the prevalence of functional impairment was 11.4%, depressive symptoms 20.7%, cognitive impairment 32.1%, and abnormal timed up-and-go test 32.1%. During the 12-month follow-up, items of mean oral medications were significantly reduced (3.2 ± 2.7 vs. 3.8 ± 2.8, p<0.001) and the health-related quality of life was significantly improved (64.6 ± 8.0 vs. 61.6 ± 4.0, p<0.001). In conclusion, patients visiting outpatient GEM services in Taiwan are old and well-educated, and they possessed various functional impairments. The outpatient GEM services significantly reduced the items of oral medications and improved quality of life. The possible better compliance of this cohort due to high educational status may overestimate the clinical effectiveness of outpatient GEM services. Further investigations are needed to clarify the long-term benefits of outpatient GEM services.
