Description
Summary:ObjectiveTo assess the level of knowledge about blood donation and associated factors in Ethiopia.DesignSystematic review and meta-analysis.MethodsBoth published and unpublished cross-sectional studies on the level of knowledge about blood donation in Ethiopia were included. Articles from different databases such as PubMed/MEDLINE, HINARI, EMBASE, Scopus, Google Scholar and African Journals Online were searched. Cochrane I2 statistics were used to check for heterogeneity. Subgroup and sensitivity analyses of evidence of heterogeneity were carried out. Egger’s test with funnel plot was conducted to investigate publication bias.ResultTwenty cross-sectional studies with a total of 8338 study participants (4712 men and 3626 women) were included. The overall nationwide level of knowledge about blood donation was 56.57% (95% CI 50.30 to 62.84). Being in secondary school and above (adjusted OR=3.12; 95% CI 2.34 to 4.16) and being male (adjusted OR=1.81; 95% CI 1.44 to 2.28) were the factors associated with level of knowledge about blood donation.ConclusionMore than half of the study participants were knowledgeable about blood donation. Sex and educational status were the factors significantly associated with level of knowledge about blood donation in Ethiopia. Therefore, there is a need for education and dissemination of information about blood donation among the general population to build adequate knowledge and maintain regular blood supply.
