Methods: A 1: 1 case-control study was conducted on the risk factors of 140 Acinetobacter baumannii infections in 4 hospitals in Chongqing from January 1, 2000 to December 31, 2000. Results: All Acinetobacter baumannii infections were nosocomial infections with a mortality rate of 9%. The main respiratory tract and surgical incision were below the infection site. Risk factors for nosocomial infections were severity, immunosuppressive agents, use of mechanical ventilation, and types of antibiotics used.
