Abstract
BACKGROUND: Preoperative type and screen and type and cross are routinely obtained in patients undergoing elective cervical spine surgeries. This is despite low perioperative transfusion rates, particularly in patients undergoing anterior cervical discectomy and fusion (ACDF). METHODS: We conducted a retrospective cohort study at a single tertiary medical center of all patients 18 years of age or older undergoing elective ACDF for degenerative cervical spine disease between January 2016 and January 2021. Our primary outcome measures included the frequency of type and screen/crossmatch orders, rate of perioperative transfusion, and crossmatch to transfusion (C/T) ratio. Secondary outcomes included differences between preoperative and postoperative hemoglobin and hematocrit. RESULTS: In total, 1,162 patients were identified. There were no cases of intraoperative transfusion. The overall transfusion rate was less than 1%, with only 1 patient receiving a blood product transfusion during their hospital admission. This patient received 2 units of platelets for severe preoperative thrombocytopenia. Yet, 961 patients (83%) received ABO/Rh blood typing and screening and 647 patients (56%) had their blood typed and crossed. A total of 1,318 units of blood were crossmatched, with no units of packed red blood cells (pRBCs) transfused and only 2 units of platelets transfused, achieving a high crossmatch to transfusion (C/T) ratio of 659:1. CONCLUSIONS: Among 1,162 patients who underwent elective ACDF at our institution, there were no patients who required an intraoperative or emergent blood transfusion. Furthermore, routine type and screen and crossmatch in patients undergoing elective ACDF at our insitution is associated with a high C/T ratio, suggestive of inefficient usage of blood products.
