Since the 80's, there is an increasing trend in the percentage of caesarean sections (CS) in Belgium. Since 1987 the number of CS has doubled. In spite of this increase, the quality of the obstetric care remains equal. The supplemental sections have no additional advantage in relation to mortality and morbidity of mother and child. The largest increase occurs in women who have little chance to get a CS in advance and the increasing number sections can not be explained by more obstetric pathologies. Probably the observed trend is dependent to nog-medical reasons such as: planning of deliveries, CS on request, medico-legal reasons, financial motives, etc. Furthermore, considerable differences in the percentage of CS between hospitals of the same category are observed. This finding questions the quality of care.
