AbstractIntroductionApheresis practices in the United States (US) have not been comprehensively characterized to date. This study aimed to address this gap by evaluating apheresis therapy through a national survey.MethodsA multi‐institutional survey was conducted between April and July 2023. The survey, comprising 54 questions, focused on institutional demographics, procedures, equipment, staffing, training, and impacts of the Coronavirus Disease 2019 (COVID‐19) pandemic. Responses from 22 institutions, primarily academic medical centers, were analyzed.ResultsTherapeutic plasma exchange (TPE) was the most common procedure, followed by hematopoietic progenitor cell collection (HPC‐A) and red blood cell exchange (RCE). CAR‐T cell collections were widespread, with some institutions supporting over 30 protocols concurrently. Most sites used the Spectra Optia Apheresis System, were managed by a transfusion medicine service, and employed internal apheresis providers. Insufficient staffing levels, exacerbated by the COVID‐19 pandemic, were common and most often addressed using overtime.DiscussionThe survey highlighted the ubiquity of TPE, expanding cellular collections and staffing challenges. The role of apheresis in supporting cellular therapy, particularly in newly developing cell and gene therapies and clinical trials, was evident. Staffing issues during the pandemic emphasized the need for innovative recruitment strategies.ConclusionThis nationwide survey provides the most comprehensive analysis to date of apheresis practices in large US academic centers.

AbstractBackgroundPrevious studies have demonstrated low first‐time donor return rates (DRR) following catastrophic events. Little is known, however, about the influence of demographic factors on the DRR of first‐time donors during the COVID‐19 pandemic, including the unique motivation of COVID‐19 convalescent plasma (CCP) donors as compared to non‐CCP donors.Study Design and MethodsThirteen blood collection organizations submitted deidentified data from first‐time CCP and non‐CCP donors returning for regular (non‐CCP) donations during the pandemic. DRR was calculated as frequencies. Demographic factors associated with returning donors: race/ethnicity, gender, and generation (Gen Z: 19–24, Millennial: 25–40, Gen X: 41–56, and Boomer: ≥57 years old), within the CCP and non‐CCP first‐time cohorts were compared using chi‐square test at p < .05 statistical significance.ResultsFrom March 2020 through December 2021, there were a total of 44,274 first‐time CCP and 980,201 first‐time non‐CCP donors. DRR were 14.6% (range 11.9%–43.3%) and 46.6% (range 10.0%–76.9%) for CCP and non‐CCP cohorts, respectively. Age over 40 years (Gen X and Boomers), female gender, and White race were each associated with higher return in both donor cohorts (p < .001). For the non‐CCP return donor cohort, the Millennial and Boomers were comparable.ConclusionThe findings demonstrate differences in returning donor trends between the two donor cohorts. The motivation of a first‐time CCP donor may be different than that of a non‐CCP donor. Further study to improve first‐time donor engagement would be worthwhile to expand the donor base with a focus on blood donor diversity emphasizing engagement of underrepresented minorities and younger donors.
