Background and Objectives: Recombinant factor VIIa (rFVIIa) is approved for treatment of inhibitors in hemophilia but has also been used for numerous off-label indications. Type of study: This study aims to validate a modified Biss scoring system in patients who received recombinant factor rFVIIa in Jeddah, Saudi Arabia. Materials and Methods: We included 70 patients who received rFVIIa for off-label indications over 12 months. Characteristics of survivor and non-survivor groups were compared including demographics, laboratory and clinical data. Using a modified Biss prognostic scoring system, based on the original scoring system used by Biss and Hanley, patients were divided into low (<1), intermediate (1-2) and high (≥3) score groups.
