New devices and products often promise to protect health-care workers and patients from transmission of viral infections. These need to be evaluated carefully for efficacy, applicability, and cost in an objective, structured manner.

Surgical and obstetric HCWs and epidemiologists will benefit from working together to describe the frequency and circumstances of percutaneous injuries in operating and delivery rooms. Rates of percutaneous injury vary among institutions, and attending and resident surgeons are among those at greatest risk for injury. Gynecologic surgery appears to have one of the highest rates of injury of the surgical specialties, and rates of injury vary by procedure within a given specialty. Suture needles cause the majority of injuries. Certain actions such as holding tissue while suturing or cutting are associated with a higher risk of injury. Many percutaneous injuries appear to be preventable. Epidemiologic data can be used to develop strategies based on the industrial hygiene model to reduce the incidence of percutaneous injury and to collect and disseminate data on the efficacy of new preventive measures. Potentially safer instruments and suture needles, technique modification strategies, and personal protective equipment such as cut-resistant gloves and finger protective strips are now available. Scientific assessment is needed of these and other new measures to determine whether they will decrease the risk of percutaneous injury, be acceptable to users, be cost effective, and avoid adverse consequences to patients or HCWs.
