The Full Outline of UnResponsiveness score is more efficient than the Glasgow Coma Scale in the prognosis of stroke

Abstract

Objectives: After being a solid method of measuring consciousness for decades,the Glasgow Coma Scale (GCS) was offered to be

replaced with a better option: The Full Outline of Unresponsiveness (FOUR) score, which several studies later confirmed to be

superior due to its independence from verbal response and ability to consider brain stem reflexes. In this study, we decided to compare

the two scales in the prognosis of stroke, which has never been conducted before.

Patients and Methods: We conducted both methods on 150 stroke patients during admission to the emergency service and assessed

them during a 3-month follow-up after discharge.

Results: The type of stroke was 80% ischemic and 20% hemorrhagic. 55.3% survived after a 3-month follow-up. The FOUR score had

a significant converse relation with hospitalization, a relation with the GCS lacked. The FOUR score also had a stronger correlation

with the outcome of stroke than the GCS. Additionally, the receiver operating characteristic (ROC) curve showed greater sensitivity

and specificity in the FOUR score in the prognoses of stroke patients.

Conclusion: We recommend using the FOUR score as the first priority.
