ABSTRACT
OBJECTIVES: In this study we describe the changes in medical practices and nosocomial infection rates in obstetrics observed through a surveillance network in the South East of France. MATERIAL AND METHOD: The maternity units which belong to this network participated in voluntary surveillance using the network's methodology. The criteria for the diagnosis of nosocomial infections were in accordance with the methods described by the Centers for Disease Control and Prevention. RESULTS: 101240 pregnancies including 18503 caesareans (18.3%) were included in the network from 1997 to 2000. During the study period, nosocomial infection rates following caesarean section and vaginal delivery decreased respectively from 7.8% to 4.3% (p < 0.001) and from 2.2% to 0.9% (p < 0.001). This evolution was compared with the evolution of collected risk factors. CONCLUSION: In spite of the methodology limits, general value of surveillance and infection control programs in maternity units has been confirmed by the results of this surveillance network. During the study period, both obstetrics-related risk factors for nosocomial infection and observed hospital-acquired infection rates were dramatically reduced, what prove an improvement of quality of care in maternity units.
