Influencing factors of the injury characteristics on the NISS in early and later elderly: Using National Hospital Discharge In-depth Injury Survey

The purpose of this study is to present policy proposals and health promotion programs for the prevention of traumatic diseases in the elderly by dividing the research subjects into early and late elderly. The data of this study were used in the 14th In-Depth Discharge Injury Survey in 2018. 7,993 patients aged 65 years or older were included among the total discharge injury patients. Data processing was analyzed with SPSS 23.0. As a result of the study, The incidence of injury was high in men(54.1%) of early elderly and in women(60.1%) of late elderly(p <.001). A large number of injuries occurred in the early elderly due to transport accidents while moving, and in the late elderly due to falls during daily life(p <.001). Early and late elderly had two metabolic syndrome factors at moderate injury(p <.001). In NISS, the most common symptoms were mild(51.1%) in the early elderly and moderate(65.3%) in the late elderly(p <.001). According to the NISS, in the early elderly, gender, route of admission, length of stay, metabolic syndrome disease, injury mechanism, place of injury and activity at injury were statistically significant(p <.001). In the later elderly, gender, route of admission, length of stay, type of insurance, metabolic syndrome disease, injury mechanism, place of injury, and activity at injury were statistically significant(p <.001). Therefore, the early and later elderly have different characteristics of injury according to the previous and later age groups, so customized prevention education and national policies and projects for the early and later elderly are required.
