National blood donor vigilance programme of India: Analysis of donor adverse reactions reported during initial 2 years of implementation (2016 and 2017)

INTRODUCTION: The donor vigilance program is intended to collect and assess information on unexpected or undesirable effects or reactions resulting from blood donation. In this report, we discuss the analysis of the blood donor adverse reactions (DARs) reported in the National Blood Donor Vigilance Programme of India during the first 2 years of implementation. MATERIALS AND METHODS: DAR reporting form prepared and approved by the National Executive Committee of the Haemovigilance Programme of India was used to capture the data by the blood centers and submitted to Donor-Vigil software prepared and hosted by the official website of the National Institute of Biologicals. Data reported for the years 2016 and 2017 were reviewed, analyzed, and validated by independent transfusion medicine experts. RESULTS: During this period, a total of 19,98,101 donations denominator data were reported, in which 1,622,600 (80.9%) were valid. A total of 6091 DARs were reported, out of which 3980 (65.35%) were found valid. Only validated numerator and denominator data were included in the analysis. Generalized DARs were the most common type of DARs reported (83.7%), followed by “others” type (7.7%), localized (7.6%), allergic (0.4%), and complications related to apheresis (0.4%). The overall DAR rate was 2.45/1000 blood donations, which was higher in apheresis donations (3.07/1000) as compared to whole blood donations (2.39/1000). The DARs rates were higher in females (3.5/1000) compared to male donors (2.3/1000) and in the first time (2.5/1000) compared to repeat donors (2.15/1000). CONCLUSION: In this report, we concluded that younger age, first time, and female donors are more prone to DARs as compared to older age, repeat, and male donors. During the analysis of the data, we found some limitations, which can be improved by upgrading the reporting form and conducting regular continuing medical education (CMEs) of participant blood centers.
