Donor knowledge and perceptions regarding donation‐induced iron depletion and iron supplementation as a blood service policy

Abstract

AbstractBackground and ObjectivesRegular whole blood donations are associated with an increased risk of iron deficiency. Iron supplementation is an effective strategy to prevent donation‐induced iron deficiency. However, research on donor perceptions towards such a policy is limited. Therefore, we aim to evaluate donors' knowledge on donation‐induced iron depletion and their perceptions regarding iron supplementation as a blood service policy.Materials and MethodsThree thousand Dutch whole blood donors were invited to complete a survey assessing their knowledge of donation‐induced iron depletion and attitudes and perceptions towards iron supplementation as a policy. Linear regression modelling was used to evaluate associations between explanatory variables and perceptions.ResultsIn total, 1093 (77.1%) donors were included in the analysis. Donors had poor knowledge of current iron management policies, but a better understanding of iron metabolism and supplementation. Iron supplementation as a policy was perceived mainly positive by donors, and the majority were willing to use iron supplements if provided. Iron supplementation was not perceived as invasive or negatively affecting donors' motivation to continue donating. Additional iron monitoring, information and donor physician involvement were regarded as important conditions for implementation. Male sex, trust in the blood service, prior experience with iron supplements and openness towards dietary supplements were strongly positively associated with willingness to use iron supplementation.ConclusionDonors' knowledge regarding donation‐induced iron depletion is limited, but not associated with their perceptions regarding iron supplementation. Donors do not consider iron supplementation as invasive, deterring or demotivating, and a majority are willing to take supplements if offered.
