Real-world economic and clinical outcomes associated with current hemostatic matrix use in spinal surgery

Aim: Bleeding during spine surgery is controlled using topical hemostatic agents. Studies have reported outcomes between Surgiflo^® and Floseal, the most widely used flowable hemostatic matrices, but have not included the latest Surgiflo formulation which is more adherent to the bleeding surface than prior formulations. Materials & methods: A propensity score-matched analysis was conducted using the Premier Healthcare Database to compare economic and clinical outcomes of adults undergoing inpatient spinal surgery between 2013 and 2018 receiving current Surgiflo or Floseal. Results: This retrospective study included 28,910 patients in each group and found comparable outcomes for bleeding events, overall transfusion rate, inpatient mortality and readmissions between Surgiflo and Floseal. Surgiflo was associated with $430 (USD) lower hospitalization costs, shorter length of stay and shorter operating room time than Floseal.
