Moderate-to-severe traumatic brain injury (TBI) is a major source of morbidity and mortality in elderly patients. Little is known about long-term mortality in elderly patients following mild, nonfatal TBI and how the injury mechanism predicts survival. This study aimed to compare long-term mortality in elderly patients with mild TBI and traumatic subdural hematoma (tSDH) due to ground-level fall (GLF) versus those with TBI and tSDH due to another cause (i.e., non-ground-level fall [nGLF]).
This retrospective study comprised 288 patients ≥60 years old from a single Level I trauma center with tSDH and Glasgow Coma Scale scores 13-15.
Median follow-up after initial TBI presentation was 2.9 years for the GLF group and 2.4 years for the nGLF group. During follow-up, 98 patients died, and median survival for all elderly patients with mild TBI and tSDH was 4.6 years. The GLF group had a higher mortality rate than the nGLF group, with 93 patients in GLF group dying during follow-up compared with 5 in nGLF group (P < 0.0001). The annual death rate for patients in the GLF group was 12.5% per year. For patients 60-69 years old, 39% in GLF group died compared with 4% in nGLF group during follow-up (P = 0.0002). Likewise, for patients 70-79 years old, 29% in GLF group died compared with 7% in nGLF group (P = 0.021). Finally, 56% of patients >80 years old in GLF group compared with 18% in nGLF group (P = 0.11).
Elderly patients with mild TBI and tSDH due to GLF have significantly higher long-term mortality than patients with injuries due to nGLF.
中重度创伤性脑损伤(TBI)是老年患者发病率和死亡率的主要原因。对于轻度、非致命性 TBI 后老年患者的长期死亡率以及损伤机制如何预测生存率,目前知之甚少。本研究旨在比较因地面坠落(GLF)导致轻度 TBI 和创伤性硬脑膜下血肿(tSDH)与因其他原因(即非地面坠落[nGLF])导致 TBI 和 tSDH 的老年患者的长期死亡率。
本回顾性研究纳入了来自单一一级创伤中心的 288 名年龄≥60 岁、tSDH 和格拉斯哥昏迷量表评分 13-15 的患者。
GLF 组中位随访时间为初始 TBI 表现后 2.9 年,nGLF 组为 2.4 年。在随访期间,98 例患者死亡,所有轻度 TBI 和 tSDH 老年患者的中位生存时间为 4.6 年。GLF 组的死亡率高于 nGLF 组,GLF 组中有 93 例患者在随访期间死亡,而 nGLF 组仅有 5 例(P<0.0001)。GLF 组患者的年死亡率为 12.5%。对于 60-69 岁的患者,GLF 组有 39%的患者在随访期间死亡,而 nGLF 组仅有 4%(P<0.0002)。同样,对于 70-79 岁的患者,GLF 组有 29%的患者在随访期间死亡,而 nGLF 组有 7%(P=0.021)。最后,80 岁以上的患者中,GLF 组有 56%的患者死亡,而 nGLF 组有 18%(P=0.11)。
因 GLF 导致轻度 TBI 和 tSDH 的老年患者的长期死亡率明显高于因 nGLF 导致损伤的患者。
