Establishment and evaluation of prognostic model of severe traumatic brain injury / 重庆医学

ABSTRACT

Objective To build the prognostic model of STBI and provide guidance for making clinical decision .Methods A total of 486 patients with STBI was collected .Six months after injury ,according to GOS ,the patients were divided into five levelsgood , mild-to-moderate disability ,serious disability ,persistent vegetative state and death .Ordinal regression analysis were used to find out the main factors of different populations .Results There were significant differences between different levels in nine factors .The re-sult of ordinal regression analysis showed that GCS ,age ,rescue time and reaction of pupil to light stood as independent variables in prognosis of patients with STBI(P<0 .05) .The outcomes from the prognostic model were pretty much exactly the same as the ac-tual results(Kappa= 0 .640 ,P= 0 .026) .Conclusion Though using the prognostic model of STBI ,the present study found out prognosis was closely related to GCS ,age ,rescue time and reaction of pupil to light in patients with STBI ;thus it could provide guidance for prognosis evaluation .
