The aim of this study was to investigate the prevalence of common geriatric conditions in a tertiary medical center. We conducted a cross-sectional, hospital-wide survey of 455 inpatients, aged 65 and older, from 24 medical and surgical units of a 2200-bed urban academic medical center in Taiwan. Patients were screened in face-to-face interviews for 15 geriatric conditions. The prevalence of geriatric conditions was determined and compared by medical versus surgical services. Our sample of participants had a mean age of 75.3 +/- 6.1 years (+/- S.D.), range = 65-92. The prevalence of geriatric conditions ranged from 5% (pressure ulcers) to 57% (polypharmacy; taking > 5 prescriptions). The majority was visually impaired (74%) and complained of sleep disturbance during their hospital stay (58%). Prevalence rates of certain geriatric conditions differed significantly between medical and surgical units, suggesting that care should address not only common conditions but also those with higher rates on different units. Furthermore, high rates of geriatric conditions indicate strong needs for care that does not fit into traditional disease models of medicine. Care should be better targeted to address different risks for geriatric conditions of medical versus surgical geriatric inpatients in acute care settings. (C) 2010 Elsevier Ireland Ltd.

Background: Identifying shared common risk factors of geriatric syndromes is clinically useful in designing a unified approach to optimizing geriatric care. Objectives: The purpose of this study was to identify older Taiwanese inpatients' common shared risk factors among seven distinct geriatric syndromes: malnutrition, depression, cognitive impairment, functional dependence, incontinence, pressure ulcers, and dehydration. Method: A cross-sectional, hospital-wide survey was conducted to enroll inpatients (N = 455) older than 65 years and admitted to 24 medical and surgical units in a 2,200-bed urban academic medical center in northern Taiwan. Malnutrition was defined as a Mini-Nutritional Assessment score less than 17.5, depression was defined as a Geriatric Depression Scale score more than 10, cognitive impairment was considered a Mini-Mental State Examination score less than 20, and functional dependence was defined as a Barthel Index score less than 50. Incontinence, pressure ulcers, and dehydration were extracted from patients' medical records. Results: Participants had a mean age of 75.3 years (SD = 6.1 years, range = 65-92 years). The prevalence of geriatric syndromes ranged from 5% (pressure ulcers) to 33% (malnutrition). The selected geriatric syndromes were shown through logistic regression analysis to be predicted by female gender (odds ratio [OR] = 1.57-2.75), functional status (OR = 0.94-0.99), cognitive status (OR = 0.82-0.95), nutritional status (OR = 0.74-0.93), and depressive symptoms (OR = 1.07-1.26), supporting the notion of shared risk factors in geriatric syndromes. Conclusions: The findings support the theory that common geriatric syndromes have a shared set of risk factors-female gender, depressive symptoms, and functional, cognitive, and nutritional status. Revising care to target these shared risk factors in preventing common geriatric syndromes is theoretically sound.
