Purpose of Study:During the COVID-19 pandemic, the FDA granted emergency use of Convalescent Plasma (CCP) as a treatment modality. Blood centers and hospitals began recruiting eligible donors, as demand exceeded supply. In the setting of an emergency, this study assessed the effectiveness of phone calls versus mailers for plasma donation recruitment.
Methods:From May to July 2019, patients that tested positive by PCR for Covid-19 were contacted to donate CCP. All patients were passively mailed a letter informing the recipient of the ability to donate CCP, as well as the need for this donation. The second group was also contacted via telephone. The callers recorded whether or not they made contact with the potential donor over the phone. Donation rates were measured for both groups and compared using a simple T-test. The phone call group was further assessed to determine the significance of donation rates between patients contacted and non-contacted.Results: A total of 1,179 potential donors were contacted (715 phone cohort, 464 mail only cohort). Conversion rates were 6.90% for the mail group and 3.92% for the phone group. The students confirmed contact with 245 (34.27%) of the patients, confirmed no contact with 303 (42.38%) and did not record contact with 167 (23.36%). Of patients who answered the phone calls, 12 (4.90%) donated, while 233 (95.10%) did not donate.
Conclusion:Conversion of potential blood donors remains a challenge. Despite the need during the pandemic, recruitment of donors was a challenge, with no statistical difference between active phone calls and passive mailers.
