External multicenter validation of the eSAH score for predicting outcomes after subarachnoid hemorrhage.

ABSTRACT: Reliable assessment of prognosis after aneurysmal subarachnoid hemorrhage (SAH) is essential to inform clinical decision-making and prevent premature assumptions of poor outcome. The enhanced SAH (eSAH) score combines three routinely available variables-age, Glasgow Coma Scale (GCS), and subarachnoid hemorrhage blood volume (SAHV)-to provide an objective framework for early outcome stratification. SAHV is estimated using the ABC/2-derived ellipsoid method applied across five major cisternal compartments on non-contrast CT. While the eSAH score has shown promise in initial derivation studies, its external performance and calibration have not yet been validated across diverse healthcare settings. We conducted a retrospective cohort study using consecutive data from two high-volume tertiary c
