Why do US source plasma donors stop donating?

Abstract

AbstractBackgroundIn the United States, source plasma (SP) donors can donate up to 104 times per year. Considering the global need for SP and plasma‐derived medicinal products, it is critical to maintain the health of frequent donors. This study explores SP donors' self‐reported reasons for a lapse in donating.Study Design and MethodsThere were 5608 SP donors from 14 SP centers who enrolled in a longitudinal cohort study to assess self‐reported functional health and well‐being. Donors were assigned to one of four groups, according to the frequency of SP donation in the 12 months before enrollment. One thousand four hundred forty‐eight SP donors who lapsed in donating during 6 months or greater during the study follow‐up were asked to complete a survey.ResultsThere were 545 lapsed SP donors who returned surveys (37.6%); 63% were female. Most responses given for stopping SP donation were categorized as convenience reasons (69.1%). Self‐reported health concerns, including being deferred multiple times, which were categorized as possibly related or unable to determine a relationship to plasmapheresis, represented 45.5% of the responses.DiscussionPrimary reasons US SP donors report for a lapse in donation were categorized as convenience (e.g., schedule conflicts/lack of time). Donor responses categorized as health concerns which have a possible or uncertain relationship to plasmapheresis were less frequent but present in all frequency groups. This study adds to the body of evidence that SP donors cease donating for a variety of self‐reported reasons with the majority not directly related to a perceived negative impact on their health.
