Abstract
INTRODUCTION: Unsafe blood product may cause transfusion-transmissible infections. The knowledge and perception of blood donors is important as it is associated with their donation behaviour and the safety of blood products. There was no validated questionnaire that assess the knowledge and perception on blood safety issues among blood donors to date. This study aimed to validate the self-developed questionnaire and evaluate the knowledge and perception of blood donor on blood safety issues. METHODS: This study was conducted in two phases, the questionnaire validation phase and the actual study phase. In phase one, the questionnaire was self-developed and the content validity was established through one expert panel meeting and two content reviewers. The questionnaire was available in only the Malay language. Testretest method was used to establish the construct and internal consistency of the questionnaire. 130 donors in the National Blood Centre were recruited to complete the self-administered questionnaire. The same group of respondents were retested after 2 weeks using the same questionnaire. After the validation of the questionnaires, a crosssectional study was conducted in the Kelantan state of Malaysia. The questionnaire comprised of 39 questions, including social demographic, knowledge of transfusiontransmitted disease and blood screening, knowledge on eligibility of donors and perception of donors towards blood safety. The knowledge score was further categorised into good and poor. During phase 2 of the study, systematic random sampling was used where every second blood donor enrolled was recruited in the study. The questionnaire took about 20 minutes to complete and was returned to the researcher on the same day. RESULTS: The reliability of the questionnaire was displayed through intraclass correlation. The intraclass correlation (ICC) value of the test-retest for the knowledge domain of the questionnaire is 0.895 (95% CI: 0.854-0.925). The intraclass correlation (ICC) value of the test-retest for the perception domain of the questionnaire is 0.891 (95% CI: 0.850-0.922). The factor analysis supported the convergence and discriminant validity of the questionnaire for all item in both domains. Out of 450 distributed questionnaires, 389 were analysed. 18.5% of the donors had good knowledge while 81.5% poor. Less than 30% donors aware that people with frequent change of sexual partner, bisexual people and male homosexual people will be permanently deferred from blood donation. Only 29.4% agreed that donors are responsible if their blood causes infection. 39.3% of the respondents agreed that donors can check their HIV status via blood donation. 10.3% and 5.4% of the respondents agreed that donors are free from infection if they wear a condom or only had oral sex when involved in prostitution. CONCLUSION: The developed questionnaires have acceptable reliability and validity. Poor knowledge and notable misperception concerning safe blood issues was found among blood donors. The Ministry of Health should incorporate safe blood education in future public awareness programmes.
