STATISTICAL ANALYSIS OF BLOOD PRODUCT USE IN PATIENTS UNDERGOING TRANSURETHRAL BLADDER RESECTION (TURB) AT THE ANDARAÍ FEDERAL HOSPITAL

Abstract

This study conducted a statistical analysis of blood component use in patients undergoing transurethral resection of the bladder (TURB) at the Federal Hospital of Andaraí, aiming to assess the real need for blood transfusion and to estimate the economic impact of the institutional policy mandating the reservation of blood components for all procedures. A total of 53 patients with valid laboratory data were analyzed, considering age, sex, preoperative hemoglobin level, and occurrence of transfusion. The mean age was 69.4 years, with a predominance of male patients (61%). The observed transfusion rate was 6.9%, consistent with data from the literature, which report rates between 5% and 10% for endoscopic bladder surgeries. The main factor associated with transfusion requirement was low preoperative hemoglobin, demonstrating a direct correlation between anemia and the need for perioperative transfusion. Based on these findings, the mandatory preoperative reservation of two units of packed red blood cells per surgery was estimated to result in a potential waste of approximately BRL 216,000.00 for every 145 TURB procedures, considering an average cost of BRL 800.00 per unit. The results highlight the importance of individualizing blood product requests based on clinical and laboratory criteria and in alignment with Patient Blood Management (PBM) principles, promoting both cost reduction and transfusion safety.
