Purpose: In Japan, many hospitals have emergency departments, but not all of them are able to treat polytrauma patients. Our hospital is a Level II trauma center. The purpose of this study is to identify our clinical outcomes and characteristics such as injury patterns and patient backgrounds.
Methods: We studied the clinical records of trauma patients at our hospital over the past 2 years. All traumas were classified by ISS. The subjects of this study were cases with an ISS of 16 or higher.
Results: 468 trauma patients (ISS ≥ 3, mean ISS 13, range 9-75) visited our emergency department from January 2020 to December 2021. The average age of the patients was 63 years, and many of them were elderly. The main causes of polytrauma were traffic accidents and falls from height. There were 208 cases of severe trauma (ISS score ≥16). 25 cases were dead on arrival. 20 patients died during hospitalization. The survival rate was 78.4%, which may be considered satisfactory. About 70% of the severe trauma cases had concurrent orthopaedic trauma and required surgery. Survival and death groups were compared. Values for age, gender, injury pattern, ISS score, Revised Trauma Score, and probability of survival were compared.
Conclusion: We researched clinical features of a Japanese single Level II trauma center. There were many elderly trauma patients because of aging society. More large number of study may be useful to understand characteristics of a Japanese trauma center.
