Purchase data: a proxy for safety status

This study demonstrated the use of purchase data to determine the incidence of sharps injuries in a major tertiary referral hospital in Australia. The incidence rates of injuries per 100,000 items purchased were 2.65 and 12.60 for syringe needles and scalpel blades, respectively. These figures were lower than those reported previously using this method. The incidence rate for injuries with suture needles, which had not been reported previously, was 31.89/100,000 items purchased. Incidence data calculated in this manner may be used in conjunction with purchase cost estimates to inform policy and practices on institutional staff safety measures.
