Needlestick injury (NSI) is an important although rare cause of the transmission of blood-borne viruses to healthcare staff. Many NSIs are avoidable. The use of universal precautions and careful sharps disposal are key factors in the prevention of injury. The availability of safety devices is increasing as it is recognized that action is necessary to prevent NSI. Devices that are easy to use and require no extra effort on behalf of the healthcare worker are preferred. There is evidence that safety devices decrease the rate of NSI. Zero-Stik Safety Syringe, manufactured by New Medical Technology, automatically retracts the needle once the injection is complete. It is simple to use and requires no formal training.
