摘要

Safety winged steel needles were introduced at the University of Tokyo Hospital in January 2001. We studied their effect in needlestick injuries. A total of 952 'needlestick and sharp-object injuries were reported. From January 1999 to December 2004, Cases of injury with winged steel needles decreased dramatically soon after safety devices were introduced, from 19.8% in Apr.-Dec.2000 to 6.7% in 2001 and 5.5% in 2002 (p < .01). They began to increase, however, in July 2002, decreased again after medical staff members mere given lectures and notices by e-mail. Due to the introduction of safety devices, cases classified as a "while recapping a used needle" and "when puncturing rubber stoppers" decreased. Among 17 injuries with safety winged steel needles, the most common cases were safety mechanism not activated safety winged steel needles could be prevented if they were used properly. In conclusion, the introduction of safety winged steel needles effectively reduced cases of injury with such needles. It is thus important to regularly remind hospital staff of safety device techniques and information reduce the such injuries.
