Abstract

Aims: To evaluate the collection and utilization of rare Rh(D)-negative blood at Cho Ray Hospital in 2025, and to analyze the relationship between blood supply and transfusion demand in order to improve the management, coordination, and effective use of rare blood resources

Materials and Methods: A retrospective descriptive study was conducted at the Cho Ray Blood Transfusion Center and Cho Ray Hospital using data collected between January 1, 2025, and December 31, 2025. The study included all Rh(D)-negative blood donors enrolled in the Southeast Rare Rh Negative Blood Club and all patients who received Rh(D)-negative blood components at Cho Ray Hospital during the study period.

Results: In 2025, the Southeast Rare Rh negative Blood Club recorded 309 Rh(D)-negative blood donors, with group O Rh(D)-negative accounting for the largest proportion. The repeat donation rate was 30.9%. A total of 280 units of Rh(D)-negative packed red blood cells (PRBCs) and 22 single-donor platelet concentrates were used, of which 67,2 % were utilized at Cho Ray Hospital. Sixty-nine patients received Rh(D)-negative blood transfusions, with a mean age of 51.8 ± 20.3 years. The Department of Hematology was the largest consumer of Rh(D)-negative blood, accounting for 36,5% of all PRBC units transfused. Packed red blood cells were the predominant blood component used, with a mean of 3.34 ± 4.49 units per patient. Most patients received ABO- and Rh(D)-identical blood components. Overall, the Rh(D)-negative blood supply from the Southeast Rare Blood Club adequately met the transfusion demand at Cho Ray Hospital and neighboring hospitals. However, AB Rh(D)-negative blood remains at risk of shortage because of the limited donor pool and its relatively high utilization compared with the number of units collected.

Conclusion: The Rh(D)-negative blood supply from the Southeast Rare Rh-Negative Blood Club largely met the transfusion demand at Cho Ray Hospital and neighboring hospitals in 2025. However, AB Rh(D)-negative blood should remain a priority in donor recruitment and rare blood inventory management because of its limited donor pool. These findings provide practical evidence for optimizing the management, demand forecasting, and regional coordination of Rh(D)-negative blood resources, thereby ensuring a safe, adequate, and timely supply of rare blood for clinical care and emergency transfusion.
