Glasgow outcome scale at hospital discharge as a prognostic index in patients with severe traumatic brain injury Escala de resultados de Glasgow por ocasião da alta hospitalar como indicador prognóstico em pacientes com traumatismo cranioencefálico grave

ABSTRACT Objective: Evaluate the Glasgow outcome scale (GOS) at discharge (GOS-HD) as a prognostic indicator in patients with traumatic brain injury (TBI). Method: Retrospective data were collected of 45 patients, with Glasgow coma scale ≤8, age 25 ±10 years, 36 men, from medical records. Later, at home visit, two measures were scored: GOS-HD (according to information from family members) and GOS LATE (12 months after TBI). Results: At discharge, the ERG showed: vegetative state (VS) in 2 (4%), severe disability (SD) in 27 (60%), moderate disability (MD) in 15 (33%) and good recovery (GR) in 1 (2%). After 12 months: death in 5 (11%), VS in 1 (2%), SD in 7 (16%), MD in 9 (20%) and GR in 23 (51%). Variables associated with poor outcome were: worse GOS-HD (p=0.03), neurosurgical procedures (p=0.008) and the kind of brain injury (p=0.009). Conclusion: The GOS-HD was indicator of prognosis in patients with severe TBI.Key words: brain Injuries, Glasgow coma scale, Glasgow outcome scale, prognosis.
