Abstract

Medical advancements over the past decades brought organ transplantation as a definitive therapy for different end-stage organ failure. However, non-availability of organs required for transplantation is a major challenge worldwide. We aimed to determine the knowledge and willingness to donate organs in various populations and settings in the Middle Eastern region. Literature searches were conducted on PubMed, MEDLINE, Cochrane, and Google scholar electronic databases. Different combinations of search terms such as "organ donation"; "knowledge", "awareness"; "beliefs", "willingness"; and "attitude" along with the country names were used. Additional searches using reference lists of studies and review articles were conducted. Data were extracted using standardized excel form and pilot tested. Three authors independently abstracted the data using a data collection form. Results from different studies were pooled for the analysis when appropriate. The search yielded 1806 articles; 1000 duplicates and review articles were excluded, and a further 792 articles not relevant were excluded. Finally, 14 original studies met the inclusion criteria. Total pooled sample size for assessing knowledge was 6697 and for willingness was 8714. Pooled overall knowledge regarding organ donation was 69% with a 95% CI [64.5, 73.5]. Pooled overall willingness to donate organ was 49.8% with a 95% CI [41.3, 58.4]. Knowledge about organ donation and willingness to donate organs varies in different population and settings in the Middle East. These in fact are linked to multiple social factors ultimately leads to 'consent' for donating organs by a potential donor. Family's influence; religious, traditional and spiritual beliefs; and status of ethnic, minority, and immigrant populace are the important determinants of the decision for organ donation. Understandings on social determinants in organ donation remain crucial and should be addressed while developing policies and organizational developments.

Keywords: Knowledge; Middle East; Organ donation; Willingness.
