Blood donation practices, motivators and barriers in the Caribbean: A narrative review.

Adequacy and safety are the twin prerogatives of the blood transfusion service which in turn is an indispensable component of public health delivery; however, many Caribbean countries have inadequate blood supply for the current and projected demands of their health care systems. Understanding blood donor motivators and barriers is crucial to improving the rate of voluntary non-remunerated blood donation (VNRD) to meet World Health Organisation (WHO) targets. The objective of this study was to review current research on the landscape of blood donation practices and attitudes in the Caribbean. We undertook a systematic search of electronic databases through September 2023 to identify studies of blood donation practices, knowledge and attitudes, including motivators and barriers to donation in the English-speaking Caribbean. We identified eight (8) relevant studies of observational study design. VNRD remain relatively uncommon; family replacement or remunerated donations were most common. Barriers to blood donation included lack of a known recipient such as a family member who needed blood, never having been asked to donate, presumed ineligibility to donate, and fear of needles or adverse reactions. Study participants indicated willingness to donate blood if provided more information about the importance of blood donation. There is a paucity of published research regarding blood donor knowledge, motivators and barriers in the Caribbean context. Such research could indicate the necessary interventions for achieving the goals of an adequate and safe blood supply.
