Abstract
The severity grading tool (SGT) was recently designed by the Association for Advancement of Blood and Biotherapies (AABB) to have more objectivity in severity assignment for an adverse donor reaction after blood donation. A study was performed in India to assess the knowledge (post-training) and determine the degree of agreement of the SGT between participating centres and the subject expert group. This prospective cross-sectional survey-based study was conducted by the National Coordinating Centre (NCC) of the National Blood Donor Vigilance Programme (NBDVP) of India. Thirty-five real-world case scenarios, validated by seven national and two international experts, were sent to the participating centres, and their responses received (diagnosis and severity grade) were compared and analysed. A total of 50 blood centres participated in the study. The overall agreement between the participating centres and the expert group was 66.4%, with a fair Kendall's coefficient of concordance (W) of 0.271 (p-value < 0.05). The degree of agreement was observed to be more than 80% for 12 centres, 60%-80% for 27 centres and <60% for 11 centres. The overall degree/percentage of agreement for cases with single and multiple types of donor adverse reaction was 71.3% and 42.6%, respectively. The SGT will be an efficient mode to have uniform objective reporting of the adverse donor reactions and may be implemented in the NBDVP of India. This study also highlights the need for training of the blood centres on the basic definitions and categorization of the donor's adverse reaction.
