What influences decisions to donate plasma? A rapid review of the literature

Abstract

AbstractBackground and ObjectivesPlasma has become an essential ingredient for various medical treatments. Many blood collection agencies rely on voluntary non‐remunerated donation when collecting plasma, but at present many do not collect sufficient plasma to meet domestic demands. This rapid review sought to explore the factors that have been found to influence people's decisions to donate plasma to inform future research.MethodsSearches were conducted in PubMed, PsycINFO, Social Sciences Citation Index and CINAHL for peer‐reviewed journal articles that discussed plasma donation and the factors associated with donor behaviour. Pertinent information from included articles was extracted and arranged in themes.ResultsIn total, 33 articles were included in this review. Three main themes were identified by the authors. The first focused on site‐level factors related to blood collection agencies' engagement with plasma donors and their influence on plasma donation experiences. The second theme considered how individual characteristics and experiences influence willingness to donate plasma. The third theme examined social and cultural‐level factors, such as how social networks and community shape perceptions and experiences with donation.ConclusionOur findings suggest that the current understanding of plasma donation is focused mainly on converting whole blood donors and also centres on individual‐level factors to donation. Further research must examine what factors attract non‐whole blood donors to become plasma donors, focusing on broader social‐level influences. This review will inform policies and interventions for blood collection agencies to increase plasma donors.
