Computer interview for screening blood donors for risk of HIV transmission.
To test the ability of a computer-based interview to detect factors related to the risk of the human immunodeficiency virus (HIV) among potential blood donors, and to determine donor reactions to the use of the computer, we compared the rate of detection of HIV-related factors elicited by the computer interview with the rate elicited by standard American Red Cross procedures (written questionnaires and face-to-face interviews) for assessment of donor suitability. The study was performed at a Red Cross blood donor center and a hospital. A consecutive sample of 294 male and female blood donors 18 to 75 years of age participated in a randomized crossover trial in which the order of the two methods was reversed. Among 272 prospective donors who provided complete data, the computer identified 12 who reported either behavior associated with a risk of acquiring HIV or symptoms compatible with AIDS. None of these 12 was so identified by face-to-face interviews or written questionnaires. Only one used the confidential unit exclusion procedure to prevent use of his donated blood. Tests for antibody to HIV were negative in blood from all 272 subjects. The subjects enjoyed the computer interview and judged it to be more private than the standard method for donor assessment.
