Purpose: This study was performed to identify the severity of after-fall injuries and the factors affecting moderate to severe injury among elderly individuals. Methods: The study included 340 patients aged 65 years and over who visited the emergency room after experiencing a fall incident. Data were retrospectively collected through electronic medical records. Results: Severity of injuries was moderate 80.9%, the most common injury type was fracture 56.2% and the most commonly injured body part was the upper limb 43.8%. After treatment at the emergency room, 51.5% individuals were hospitalized. Of those hospitalized, 32.6% patients received an operation. Analysis was done of risk factors affecting falls with moderate to severe injury. The results revealed that falls in patients aged 85 years or older were 2.72 times more likely than patients aged 65~74 years. Falls were 4.21 higher in patients taking 1~2 medicines compared to patients not taking medicine. Conclusion: Injury after the fall in the elders was severe. In order to minimize post-fall injuries, it is necessary to perform emergency treatment after falls, to visit the hospital facility promptly. It is also necessary to educate patients to be aware of the side effects of the drugs they are taking.
