    Introduction: Unsafe blood products cause transfusion-transmissible infections. A good knowledge and perception about blood safety issues is crucial to ensure safe blood supply. The objective is to develop and validate a question- naire about the knowledge and perception among blood donors on blood safety issues. Method: A cross-sectional study was conducted among 130 blood donors who attended the National Blood Centre, Kuala Lumpur in April and May 2018. The questionnaire was developed in the Malay language after extensive literature search. The self-admin- istrated questionnaire consisted 39 items which required around 20 minutes to complete. The validation involved content validity, construct validity using exploratory factor analysis and reliability using test-retest analysis in IBM SPSS statistics. The same group of respondents was retested after two weeks using the same questionnaire. Results: Content validity was established through multidisciplinary expert meeting and two content reviewers. The factors loadings of all questionnaires were more than 0.40. Knowledge questions were divided into three domains; percep- tion questions were divided into four domains. The intraclass correlation (ICC) values of the test-retest were more than 0.80 for the three knowledge domains and more than 0.60 for the four perception domains. The third domain of the perception section which consisted two questions had the lowest ICC value of 0.686 (95% CI 0.583-0.767). One of the questions was restructured to improve clarity. Conclusions: The questionnaire on knowledge and perception on blood safety issues has good validity and reliability, with appropriate items which warranted its utilization among blood donors.

    Introduction: Unsafe blood products cause transfusion-transmissible infections among blood receivers. The knowledge and perception of blood donors is important as it is associated with their donation behaviour and hence the safety of blood products. There was no previous study that assessed the knowledge and perception on blood safety issues among blood donors to date. The objective of this study was to assess the knowledge and perception of blood
    donors on blood safety issues.
    Methods: This was a pilot study conducted to pilot test the self-developed questionnaire by the researchers. The questionnaire was available in the Malay language. One-hundred-thirty donors at the National Blood Centre were recruited to complete the self-administered questionnaire. Health sciences professionals, medical students and non-Malaysians were excluded in this study.
    Results: A total of 130 donors comprising of 70 males (53.8%) and 60 females (46.2%) responded. The mean age of the respondents is 32.48±8.86 years. Most of the respondents were Malay (55.4%), single (49.2%), working in private sector (46.9%) and regular donor (68.5%). More than half of the respondents did not know that dengue, Zika and mad-cow disease can be contracted through blood transfusion. Ten percent of the respondents answered that bisexual people are eligible to donate blood. 40.7% of the donors agreed to check their HIV status through blood donation. Majority of the donors (60.7%) agreed that the donors’ blood is safe if the screening test is negative. Whereas, 33.9% of the donors disagreed that they shall be responsible if their blood causes infection.
    Conclusion: Several knowledge gaps and inappropriate perception among the respondents were identified and these might affect the safety of the blood products. Targeted measures should be taken to rectify donors’ knowledge and perception in order to minimise inappropriate blood donor behaviours and reduce unsafe blood products.

    Photochemical treatment is one of the pathogen inactivation method to treat plasma, part of a proactive approach used for blood and blood component safety. Three photochemical treatments that have been used were methylene blue, riboflavin and psoralen treatment. This study was done on Fresh Frozen Plasma (FFP) to evaluate the treatment effects of psoralen, methylene blue and riboflavin on coagulation factors level. Methods: FFP was collected from apheresis plasma units and kept at 22oC to 24oC. A sum of 90 apheresis plasma units and segments were used, separated from each bag and a part used as controls, placed in a -30oC freezer for storage, thawed, and coagulation proteins function was evaluated before and after treatment, at immediate, 30 days and 270 days storage. Results: Significant differences in fibrinogen and coagulation factor levels between before and after treatment with methylene blue, psoralen and riboflavin. However, most of the mean values in treated plasma were within reference ranges. Methylene blue treated FFP showed the lowest changes in fibrinogen and other coagulation factors level whilst riboflavin treated FFP demonstrated the highest changes in coagulation proteins concentrations especially for fibrinogen, FV, FVIII, FIX and FXII. However, FXIII showed the best recovery for all three photochemical methods with reduction level of 3% to 8% compared to pre-treatment. Storage time comparison of immediate, 30 days and 270 days was inconclusive. Conclusion: The coagulation proteins in psoralen treated FFP and MB-FFP were adequately preserved, where MB-FFP showed better preservation than other two photochemical treatments.

    Background: Unsafe blood products may cause transfusion-transmissible infections. This study aimed to evaluate the knowledge and perceptions of blood donors regarding blood safety.

    Methods: This was a cross-sectional study conducted in the Kelantan state of Malaysia. The questionnaire comprised 39 questions that covered areas such as donors' social demographic information, knowledge of transfusion-transmitted diseases, blood screening and donor eligibility and perceptions towards blood safety. The knowledge score was categorised as good or poor.

    Results: Of the 450 distributed questionnaires, 389 were suitable for analysis. Only 18.5% of the donors had good knowledge, with 81.5% having poor knowledge. Less than 30% were aware that people with multiple sexual partners, bisexual people and male homosexual people are permanently deferred from blood donation. Only 29.4% agreed that donors are responsible if their blood causes infection. Furthermore, 39.3% assumed that they could check their HIV status through blood donation, and 10.3% and 5.4% of the respondents believed that donors are free from infection if they wear a condom during sex or only have oral sex when involved in prostitution, respectively.

    Conclusion: Poor knowledge and notable misperceptions concerning safe blood donation were found among blood donors. The Ministry of Health should incorporate safe blood education in future public awareness programmes.

    Transfusion of blood is a life-saving intervention that saves many lives. Unsafe practices in blood donation and pre-transfusion testing place people's lives at risk of transfusion transmissible infections (TTIs). The study aims to determine the overall seroprevalence of the selected TTIs for the past 5 years (2013-2017) among blood donors from a hospital in Region 3, Philippines. The trend and distribution of the TTIs according to age group, sex, donor category, and number of donations were also determined. Data extracted include the age, sex, donor category, number of donations, and screening results of all donors from January 2013 to December 2017. The overall seroprevalence of the selected TTIs from over the 5-year period is 4.17%. The seroprevalence rates of hepatitis B, hepatitis C, HIV and syphilis from 2013 to 2017 are 2.87%, 0.48%, 0.10%, and 0.62%, respectively. The age group of 25 to 44 years old showed the highest rate of reactive donors. Also, higher rates of reactive donors are seen among male donors, replacement donors, and first-time donors. The overall seroprevalence of TTIs in the study locale is low and it shows a decreasing trend from 2013 to 2017. Donors who are 25 to 44 years old, males, replacement, and first-time donors showed highest seroprevalence rates of TTIs.
