Attitudes of operating theatre staff to inoculation-risk cases.

In a 12-month period, 177 patients at risk of infection with human immunodeficiency virus (HIV) or hepatitis B were operated on. Sixty-nine had HIV antibodies. The procedures used to identify these patients and minimize the risk of infection of hospital staff in the operating department are described. All staff working in the operating department were surveyed to determine their caseload, feelings of anxiety, and the incidence of high-risk exposure to infection. Anxiety was not related to workload, but was more common in those who had high-risk exposure. All members of staff who sustained a needlestick injury were tested for HIV antibodies at intervals after injury; 33 also volunteered to be tested in a screening session 3 months after the study period. None had HIV antibodies, suggesting that the risk of acquiring HIV infection in the operating department is low.
