Background and Objectives Donor screening alone cannot eliminate the risk of transfusion-transmitted HIV infection. Donor deferral according to established criteria is a supplemental strategy, which has focused largely on men who have sex with men (MSM). A study was conducted to determine the compliance of non-MSM donors with such criteria and examine its implications on blood safety. Materials and Methods Chinese donors who have just donated blood at blood donor centres in Hong Kong were recruited. Based on the contents of the routinely administered predonation Health Screening Questionnaires, participants were requested to complete a survey to assess their practice of deferrable risk behaviours and lifestyle encounters, using tablet computers. Results Over an 8-week period in mid-2016, 1614 donors (male-to-female ratio 1·23) had enrolled in the survey, accounting for 40% of donors giving blood on the survey days. The proportion of respondents who gave blood despite having deferrable HIV risk was 5%: MSM 1·2% (of the male donors); non-MSM risk behaviours 2·6%; risky lifestyle encounters 2·1%. If inconsistent declaration and suspected risk behaviours were included, the total non-compliance rate became 10·8%. Male donors had a higher prevalence of deferrable behavioural risk, even after excluding MSM. Unawareness and non-acceptability were main reasons for non-compliance. Conclusion The non-compliance rate of donors to deferral was high, although the ultimate infection risk might be small in the presence of universal screening. Simplification of questionnaires, focus on time-limited deferral and a reduction of deferral items may improve the deferral mechanism without compromising blood safety.

Background Source reduction is important in minimizing bacterial-contaminated risk of blood products, but previous evaluation of chlorhexidine (CHX) was confounded by inability of Tween and lecithin to neutralize CHX. The study aims to address this limitation and also evaluates the effectiveness of two CHX–alcohol-based skin disinfectants in blood donation setting. Methods A two-stage observational study was conducted. A single step 2% chlorhexidine gluconate/70% isopropyl alcohol brush (CHX/IPA-1) was first compared with current skin disinfection procedure consisting of sequential application of 10% povidone-iodine and 70% isopropyl alcohol (PI/IPA). Standard plates with conventional neutralizers (0·3% Tween-80, 0·1% lecithin) were used to enumerate residual bacterial counts. Then, CHX/IPA-1 was compared with another applicator CHX/IPA-2 with identical disinfectant contents using in-house plates with neutralizers (3% Tween-80, 0·3% lecithin, 0·1% histidine, 0·5% sodium thiosulphate, 3% saponin, 1% ether sulphate) having enhanced ability to neutralize CHX. Results All three products were found to reduce plate counts by > 2 log10 after disinfection. The CHX/IPA-1 group gave fewer residual bacterial growth on standard plates than PI/IPA group (5·9% vs. 61·7%, P
