Evaluation of a safety resheathable winged steel needle for prevention of percutaneous injuries associated with intravascular-access procedures among healthcare workers.

Objective: To compare the percutaneous injury rate associated with a standard versus a safety resheathable winged steel (butterfly) needle.

Design: Before-after trial of winged steel needle injuries during a 33-month period (19-month baseline, 3-month training, and 11-month study intervention), followed by a 31-month poststudy period.

Setting: A 1,190-bed acute care referral hospital with inpatient and outpatient services in New York City.
