Blood-donor perceptions of health history screening with a computer-assisted self-administered interview.

Background: Computer-assisted self-interviewing (CASI) has been shown to promote disclosures of sensitive information. Using CASI to screen blood-donor candidates might encourage reports of deferrable risks without discouraging eligible donors.

Study Design And Methods: In 1998, an anonymous mail survey was sent to donors from eight blood centers. The relationship of donor demographics, donation history, and infectious risks (HIV test-seeking behavior, unreported deferrable risk, or reactive donor-screening test result) on attitudes toward CASI were assessed.

Results: Of 92,581 blood donors surveyed, 52,650 (57%) responded; of these, 4713 (7%) had an infectious risk. Among donors with risks, 29 percent felt they would be encouraged to reveal personal data, and 7 percent reported they would be discouraged from donating by CASI. Young, minority, female, and first-time donors were the most likely to report that CASI would encourage personal disclosures. Among donors without risks, 5 percent felt CASI would discourage them from donating.

Conclusions: Although most donors felt their donation practices would not be influenced, CASI might reduce the proportion of donors with infectious risks by fostering personal disclosures and self-deferrals. The potential for CASI to improve donor screening and increase appropriate self-deferrals should be balanced against the possible loss of reluctant safe donors.
