BACKGROUND: To date, most studies on deferral of blood donors have focused on men
who have sex with men (MSM) and/or injecting drug users. Few have examined
deferrable risk behaviors relating to transfusion-transmissible infections (TTIs)
in general. This study aimed to examine the prevalence of, and factors associated
with, nondisclosure of TTI-related risk behaviors in donors. STUDY DESIGN AND
METHODS: Chinese-speaking donors who had just given blood in Hong Kong were
invited to self-complete an anonymous questionnaire. Practices of one or more of
seven deferrable risk behaviors associated with TTI were inquired. Factors
associated with noncompliance with self-disclosure were evaluated by logistic
regression. RESULTS: Over a 4-week study period in 2012, a total of 1143 donors
were recruited. Overall, 0.2% gave a history of drug injection, 1.7% had had sex
with sex worker(s), and 0.3% had had sex with a human immunodeficiency
virus-infected partner, while none had been paid for sex. Some 1.5% of male
donors reported having same-sex behaviors. Factors associated with noncompliance
were male gender (odds ratio [OR] 31.1; 95% confidence interval [CI], 3.7-263.6),
having multiple sex partners (OR, 89.7; 95% CI, 28.7-279.9), and previous history
of temporary deferral (OR, 11.4; 95% CI, 2.5-53.3). If suspected noncompliance
was included, the overall prevalence of nondisclosure of deferrable behaviors
could be high at 6.5%. CONCLUSION: Albeit uncommon, some donors fail to provide
accurate answers to predonation screening questions and are not deferred
appropriately. There is room for improvement to make deferral policy acceptable
and understandable, so as to minimize the risk of TTI. Efforts are also needed to
tackle the paucity of data on noncompliance of non-MSM donors.
