AB OBJECTIVE: To estimate the prevalence of human immunodeficiency virus
(HIV) infection among health care workers who donate blood. DESIGN:
Point prevalence survey of blood donors. SETTING: 20 U.S. blood centers
that participate in an ongoing interview study of HIV-seropositive blood
donors. MEASUREMENTS: Prevalence rates for HIV in persons who reported
being health care workers were measured directly for 6 of the 20 blood
centers. For the other 14 centers, we derived the numerator from the
interview study in the same manner used for the 6 centers; we estimated
the denominator using blood collection logs at those centers and
extrapolations from the survey completed at the 6 blood centers.
RESULTS: Between March 1990 and August 1991, 8519 health care workers
donated blood at 6 hospitals and other medical facilities. Three persons
were HIV seropositive: Two reported being health care workers and having
nonoccupational risk factors for HIV infection; the occupation and other
possible risk factors of the third seropositive donor could not be
determined. Therefore, the highest overall prevalence of HIV infection
among health care worker donors at these 6 centers was 0.04% (3 of 8519;
upper limit of 95% CI, 0.1%). We estimated that during the same period,
approximately 36,329 health care workers were tested for HIV at all 20
centers. Twenty-seven persons infected with HIV who donated at hospitals
were identified; 7 did not return for interviews, so their health care
occupations could not be verified. Thus, the highest estimated overall
prevalence of HIV infection among health care worker donors at the 20
centers was 0.07% (27 of 36,329; upper limit of CI, 0.1%). Of the 20
known health care worker donors, 11 reported nonoccupational risks for
HIV infection; 3 of the remaining 9 health care workers described
occupational blood exposures that could have resulted in transmission of
HIV. CONCLUSIONS: Blood donors can serve as a sentinel cohort when
evaluating the risk for occupationally acquired HIV infection. These
findings suggest that among the many health care worker donors in this
study, HIV infection attributable to occupational exposure was uncommon.
