In older patients, ground-level falls are the most common cause of injury. Many intrinsic and extrinsic factors influence ground fall injuries. However, the characteristics and severity of ground fall injuries have not been compared according to the activity levels. We compared the characteristics of ground fall injuries by the activity level to establish a preventive strategy for ground fall injuries in older patients. We retrospectively reviewed the records of older patients who were admitted to six university hospitals for ground-level fall injuries from 2011 to 2020. The patients were classified into active and inactive groups. Active activities were defined as paid work, exercise and leisure activities. General and clinical characteristics of both groups for ground-level fall injury were analyzed. Propensity score matching analysis (1:1) was performed for baseline characteristics (sex, age and alcohol consumption). A total of 33,924 patients were enrolled, of which 4887 (14.4%) were classified in the active group. Injury severity was not different between the active and inactive groups. The main factors significantly associated with ground fall injuries during activities in elderly patients were male sex, age from 65 to 74 years and 75 to 84 years compared to greater than 85 years, an injury time other than 00:00–05:59, alcohol consumption, sloping floor and floor type other than concrete. After propensity score matching analysis, the factors associated with ground-level fall injuries in older patients when they were active were a time of injury from 06:00–17:59 compared to 00:00–05:59, slippery floor, slope, the absence of obstacles and type of floor other than concrete. We should establish preventive strategies for reducing ground-level fall injuries in older patients during activity, which could include wearing compatible footwear, caution on sloping areas, and maintenance of unpaved roads.
