Abstract
OBJECTIVES: The cesarean delivery (CD) rate is increasing worldwide. An internationally recognized classification system had been required to analyse the trend and its possible consequences in a standardized manner. The goal of this study was to identify the main contributors to the CD rate at the Medical University of Vienna in an 11-year time period (2003-2013) and to analyse neonatal outcome parameters within the ten Robson categories. METHODS: This is a retrospective data-analysis of singleton and twin pregnancies in cephalic, breech and transverse presentation with a gestational age between 23 and 42 weeks. The cases were divided into ten classes based on the Robson criteria. CD rates and perinatal outcome parameters were analysed within each Robson class. The outcome parameters included: NICU-admission rate and 5 min Apgar score values < 7. RESULTS: The overall CD rate was at 44.2%. Within Robson class 5 the CD rate was the highest at 99.1%. Main contributors were Robson class 5 at 20.6%, followed by class 2 at 17.1% and class 8 at 15.0%. Neonatal outcome analyses revealed significant differences between the Robson classes. CONCLUSIONS: The main contributors to the CD rate were determined. We suggest reconsidering the frequently applied birth mode especially for Robson class 2, 4, 5 and 8. Lowering the CD rate could be achievable, if a careful delivery management and an individual risk evaluation is provided. It is important to reduce the CD rate in the individual Robson classes under consideration of perinatal outcome parameters, since a reduction should only take place where it is clinically useful and relevant.
