Khảo sát kết quả sàng lọc trước hiến máu của người hiến máu tình nguyện tại các điểm tiếp nhận máu lưu động của Trung tâm Truyền máu Chợ Rẫy

Voluntary blood donation is a cornerstone of modern healthcare, ensuring a steady supply for medical treatments. The Cho Ray Blood Transfusion Center (TTTMCR) places significant importance on managing mobile blood collection sites, as these locations are critical for maintaining the quality and volume of the blood supply. Understanding the characteristics of voluntary blood donors (VBDs) who are deferred from donating is crucial for developing effective communication and mobilization strategies. This study aims to identify the specific features of deferred VBDs at TTTMCR's mobile collection points, utilizing data from self-screening questionnaires and pre-donation tests to enhance the safety and efficiency of the blood donation process.

This cross-sectional descriptive study investigated the characteristics of voluntary blood donors (VBDs) deferred from donation at mobile blood collection sites managed by the Cho Ray Blood Transfusion Center (TTTMCR) between February and April 2025. Out of 25,702 registered VBDs, 2,934 (11.41%) were deferred. The study utilized self-screening questionnaires and pre-donation tests, specifically assessing hemoglobin (Hb) levels and Hepatitis B surface antigen (HBsAg) status. Key findings revealed that female donors accounted for a significantly higher proportion of deferrals (92.81%) compared to males (7.19%, p<0.01). Furthermore, the majority of deferred VBDs were over 40 years old. Geographic analysis indicated significant variations, with Dong Nai province exhibiting the highest number of deferrals. The primary reasons for deferral were ineligible Hb levels (9.65%), followed by self-screening questionnaire responses (1.36%), and positive HBsAg test results (0.4%). These insights are vital for refining blood donation strategies, particularly in developing targeted interventions. The findings emphasize the need for specialized education and health counseling for female donors and older individuals, focusing on nutritional improvements and chronic disease management, to mitigate deferral rates and ensure a more stable and safe blood supply for medical facilities.
