[Accidental pricking by a needle in a third-level hospital: associated factors].

The needlestick injuries are the most frequent accidents among hospital staff. The aim of this study is to identify some factors associated with accidents caused by needlestick injuries at hospitals, so as to measure the risk that they present. A case-control study has been made, the subject of which is the nurses working at "Reina Sofía" Hospital in Córdoba and within the period June 30, 1990 and June 30, 1991. A more significant factor in relation to needlestick injuries was the recapping of the needle after being used. The risk of injury being 3.95, 7.68 an 17.85 times higher between those who recapped sometimes, frequently and always, respectively, versus those who had never recapped needles. Professional experiences resulted in being a protector factor against the needlestick injuries (OR = 0.93; 95% CI = 0.89; 0.97;) it's estimated that the risk injuring is less than half among personnel having ten years of experience. Knowing these risk factors is important for the development of specific prevention programs. Nevertheless, it is still important to identify other risk factors.
