Needlestick injury in surgeons: what is the incidence?

A prospective study by questionnaire was carried out to investigate the incidence of needlestick injury in the operating theatre staff of a teaching hospital and to calculate the individual risk of acquiring blood-borne virus infection in the UK from this source. The individual rate of needlestick injury in operating theatre staff was 1.55% per surgeon per operation (confidence interval (Cl) 0.6-2.5%). The calculated rate of clinical hepatitis B in surgeons compared with the observed rate suggests that needlestick in theatre is the main mode of transmission.
