  "abstract": "Introduction: Hip arthroplasty is a major surgical procedure frequently associated with significant blood loss and the need for transfusion support. Understanding the transfusion characteristics of these patients is essential for transfusion service planning, the rational management of blood components, and the development of Patient Blood Management strategies. However, information regarding this profile in referral hospitals in the Brazilian Amazon region remains scarce. Objective: To characterize the transfusion profile of patients undergoing elective hip arthroplasty at a referral hospital in the Brazilian Amazon region by evaluating transfusion frequency, red blood cell concentrate utilization, blood group distribution, and the period of greatest transfusion demand during the perioperative period. Materials and methods: This retrospective, descriptive study was approved by the Research Ethics Committee (Approval No. 8,574,024) and conducted through a review of the medical records of 129 patients who underwent elective hip arthroplasty at Fundação Hospital Adriano Jorge (FHAJ), a referral hospital in the Brazilian Amazon region, between 2024 and 2025. Data collected included ABO/Rh blood groups, transfusion occurrence, the number of red blood cell concentrate units transfused, and the timing of transfusion (preoperative, intraoperative, and postoperative). Categorical variables were described using absolute and relative frequencies. Results: Of the 129 patients evaluated, 34 (26.3%) received perioperative transfusions, consuming a total of 84 units of red blood cell concentrates. The median number of units transfused was 2 per patient (IQR, 1–3). Of all transfused units, 37 (44.0%) were administered intraoperatively, 36 (42.9%) postoperatively, and 11 (13.1%) preoperatively. Eight patients received transfusion support during both the intraoperative and postoperative periods. The predominant blood group was O Rh-positive (51.9%), followed by A Rh-positive (28.7%) and B Rh-positive (6.2%), whereas Rh-negative phenotypes were infrequent (O Rh-negative and A Rh-negative, 3.1% each). No patient experienced a transfusion reaction. Discussion and conclusion: The finding that 86.9% of red blood cell concentrate utilization occurred during the intraoperative and postoperative periods demonstrates that the greatest transfusion demand takes place during and immediately after surgery, indicating that transfusion planning should prioritize these phases. The transfusion profile identified provides evidence to support the rational management of blood components, optimizes healthcare planning in referral hospitals, and reinforces the implementation of Patient Blood Management strategies in elective orthopedic surgery.",
