Japan's population has been skewing toward the elderly, but the outcomes of advanced elderly trauma are not clear. Here we compared the outcomes of very elderly trauma patients (≧85 years old) with those of 65- to 84-year-old trauma patients. We retrospectively reviewed the medical records of patients treated at Hyogo Emergency Medical Center from August 2010 to August 2016; 631 patients were entered in the study. We divided them into the younger geriatrics (YG group, 65-84 years old: n=534) and older geriatrics (OG group, ≧85 years old: n=97). The group's patient characteristics, mortality, 1-year survival rate, and Barthel index were tabulated and compared. The patients' mean age was 75.6±7.5 years. There was no significant difference in mortality between the YG and OG groups (9.6% vs. 15.1%, odds ratio [OR] 1.73; 95% confidence interval [CI] 0.93-3.23, p=0.083). The 1-year survival rate (94.4% vs. 77.8%, OR 0.19, 95% CI 0.07-0.51; p < 0.01) and Barthel index (Median score; 100 (IQR: 85-100) vs. 80 (IQR: 15-95), OR 0.98, 95% CI 0.97 to 0.99, p < 0.01) differed significantly between the groups. Our study did not find a significant difference in-hospital mortality between patients in the YG group and those in the OG group.
