A two years retrospective cross-sectional study of donor deferrals in voluntary blood donation camps in a tertiary trauma and orthopaedic centre
Abstract
Introduction: Blood transfusion system is an important component of current modern health care system.Blood transfusion plays a pivotal role in saving lives in medical and surgical conditions and requires a continuous, adequate and safe supply of blood.
Materials and Methods:A retrospective, cross sectional descriptive study was conducted on blood donors in voluntary blood donation camps of tertiary trauma and orthopaedic centre over a period of two years. Donors were selected based on the standard guidelines. Predonation screening of donors was done using donor questionnaire, physical examination, haemoglobin estimation and blood grouping. Demographic data were collected from the donor deferral registry. The causes of deferral were categorized as temporary and permanent.Descriptive statistics were used to summarize data.
Results: In this two-year study 4,071 donors were registered; 3,668 (90.10%) qualified for donation and 403 (9.90%) were deferred. Among those who were deferred, females (284, 70.47%) outnumbered men. Temporary deferrals (360,89.33%) were common than permanent deferrals (43, 10.67%). Low hemoglobin was common cause for temporary deferral (35.48%) and hypertension for permanent deferral (6.45%).
Conclusion: There is a wide spectrum of variation in deferral rates of blood donors and its causes could be due to diversity in donor selection criteria, level of public awareness, environment and socio-economic status. In order to meet demand for blood and its products, blood bank should strive to recruit new donors efficiently and should retain existing donors. Effective measures should be implemented to raise awareness about blood donation and to encourage regular voluntary donations.
