Unbiased estimates of incidence rates of accidents with blood contaminations (ABC) and time trends is the milieu for assessing the effectiveness of preventive interventions. A standardised procedure for registration and follow-up of ABC was et up in a North Italian hospital since 2002. Accurate estimates of rate denominator, as full-time equivalent (FTE) person-years, was calculated, for exposed workers only and excluding periods of prolonged absence. In the observation period (2004-2011), training courses for head nurses on security procedures were repeatedly carried out as well as the progressive introduction of vacuum blood collection systems (since 2009). 1287 ABC have been reported, corresponding to an overall annual crude incidence rate of 4.73 per 100 FTE. Temporal trends, calculated on the biennial incidence, resulted in a reductions over the time period considered, in particular for needlestick injuries. Our results support the notions on the efficacy of the adopted prevention measures.
