Chasing zero: our journey to preventing surgical site infection.

After an increase in methicillin-resistant Staphylococcus aureus infections was discovered at a health care facility in Arizona, a multidisciplinary team convened to investigate the underlying problem and work toward eliminating surgical site infections. The team investigated environmental factors, held inservice sessions to reinforce sterile technique, and made important changes to the facility culture in efforts to eliminate surgical site infections. The team's efforts were put into practice on October 30, 2008, and only one surgical site infection was identified in the following seven months.
