Effectiveness of Nosocomial Infection Control in Cardiac Surgery

Objective To evaluate the effectiveness of nosocomial infection control in cardiac surgery.Methods We collected records of surgical cases between January 2007 and December 2009 in People's Hospital of Peking University and analyzed the status of nosocomial infection in cardiac surgery before and after intervention,which was initiated in May 2008 and fully implemented since 2009.The nosocomial infection rate before and after intervention was compared.Results The rate of nosocomial infection in cardiac surgery was high in 2007 and 2008,reaching 6.07% and 7.56%,respectively.Meanwhile,the rate of nosocomial infection throughout the whole surgical system was 1.34% and 1.38%.After the adoption of intervention,the rate of nosocomial infection in cardiac surgery significantly decreased to 3.62% compared to the rate before intervention(χ2=7.584,P=0.006).Conclusions Cardiac surgery patients have high risk of nosocomial infection.Taking appropriate intervention measures for nosocomial infection control can effectively reduce the rate of nosocomial infection in cardiac surgery.
