Purpose: The purpose of this study was to examine elder care related knowledge, attitudes, nursing practice and awareness of elder abuse in geriatric hospital health personnel. Methods: The participants were 382 health personnel from 7 geriatric hospitals in 3 cities. Questionnaires contained structured questions on geriatric hospital health personnel's knowledge, attitudes, nursing practice and elder abuse awareness. Descriptive analysis, t-test, one-way ANOVA, Scheffé test and Pearson correlation coefficients were used with SPSS/WIN 12.0 program for data analysis. Results: Knowledge level of nurses was significantly higher than that of nurse assistants or caregivers (p=.002). Nursing care performed by caregivers was significantly higher than that of nurse assistants or nurses (p<.001). Attitude and elder abuse awareness did not make a significant difference according to occupation. Attitudes, knowledge and nursing practice were partially correlated. The level of nursing practice performed by nurses, nurse assistants or caregivers correlated with elder abuse awareness. Conclusion: The results of the study indicate a need for appropriate education and clinical guidelines on elder abuse for geriatric hospital personnel. More studies are needed to identify factors influencing elder abuse in geriatric hospitals.
