Challenges with Formulating Accurate Prognosis for Patients with Severe Acute Brain Injury.

Abstract

Prognostication is fundamental to determining the intensity of care offered for many critically ill patients with severe acute brain injury (SABI). Inherent uncertainties linked to predicting outcomes for patients with SABI primarily arise from a lack of complete data regarding the natural disease/injury progression that follows various forms of SABI, stemming from early withdrawal of life-sustaining treatment. This potential bias has led to limitations in using outcome data associated with clinical grading scales and a risk of perpetuating high mortality following SABI, leading to self-fulfilling prophecies. The aims of this article are to (1) review contemporary prognostication practices among clinicians for patients with SABI, (2) discuss inherent challenges in prognosticating outcomes following SABI, (3) summarize statements and guidelines from professional societies regarding SABI prognostication, and (4) identify directions for future research in prognostication after SABI.
