Abstract
Traumatic brain injury with a Glasgow Coma Scale (GCS) score of 3–5 is characterized by severe injury, poor prognosis, and low survival rates. Deciding between aggressive neurosurgery and treatment discontinuation is challenging among older adults. This study analyzed the characteristics, treatment, and outcomes of acute subdural hematoma (ASDH) in older adults with a GCS score of 3–5 to assess the benefits of surgery and guide future treatment decisions. We analyzed the data of 205 older adults (aged 65 years or older) with ASDH and a GCS score of 3–5 registered in the Korean Neuro-Trauma Data Bank System from January 2018 to June 2021. The patients were divided into death and survival groups, and the demographic, clinical, and radiological characteristics; treatment methods; mortality rates; and treatment outcomes were analyzed, along with the relationship between variables and mortality. We also compared the Glasgow Outcome Scale–Extended (GOSE) scores and investigated whether surgical treatment affected mortality and good recovery rates according to age. According to the GOSE, 76.1% of patients died, 12.7% survived in a vegetative state, 3.9% had severe disabilities, and only 4.0% showed good recovery. The GCS score at admission was significantly associated with pupil reactivity; Rotterdam computed tomography score; time interval from injury to operation and arrival to operation; treatment; and hospital stay between patients who died and those who survived. Surgical treatment was significantly associated with a lower mortality rate but not with good recovery rates.
