 AB    OBJECTIVE: The primary purpose of this study was to estimate the risk of
       HIV transmission from physicians to patients during invasive radiologic
       procedures and to compare this estimate with those previously derived
       for surgical procedures so that policy on possible practice restrictions
       can be decided. The risk of HIV transmission from patient to physician,
       including cumulative career risk for interventional radiologists, was
       also estimated. MATERIALS AND METHODS: The risk of HIV transmission from
       physician to patient and vice versa was estimated with computer modeling
       techniques, using available data on prevalence of HIV infection, rates
       of injury during invasive radiologic procedures, and risk of viral
       transmission after an exposure. Cumulative career risk of occupational
       infection was estimated with a computer simulation model. RESULTS: If
       the physician's HIV status is unknown, the risk of transmission of HIV
       to a patient during a procedure is estimated to be 0.03 per million
       procedures (95% confidence interval, 0-3.8 per million procedures). If
       the physician is known to be HIV-positive, the risk of transmission to a
       patient is estimated to be 7.5 per million procedures (95% confidence
       interval, 0-15.3 per million procedures). The estimated risk of
       transmission from patient to physician ranges from 0.03 to 7.5 per
       million for a single procedure, and the cumulative risk of occupational
       HIV infection over 30 years is estimated to be 0.009-16%. CONCLUSION:
       The estimated risk of HIV transmission from physician to patient during
       invasive radiologic procedures is so low that global practice
       restrictions on HIV-infected interventional radiologists are not
       warranted. As recommended by the American Medical Association and the
       Centers for Disease Control, decisions on possible practice restrictions
       should be made on a case-by-case basis rather than a priori. The risk of
       HIV transmission from patient to physician is also low, but real. The
       cumulative career risk of occupational infection with HIV may vary
       widely based on individual circumstances and the patient population
       served.
