Obstetrical care is characterised by an uneven distribution of deliveries. Simultaneous deliveries impose naturally an increased workload. We hypothized that a delivery might by influenced by the previous delivery, if the time interval between the two deliveries would be short enough; i.e. a shorter time interval between two deliveries could be associated with a change in the mode of delivery and possibly with perinatal mortality. Our aim was to analyse whether the time interval between two deliveries would be associated with the mode of delivery, to define a period of dependence of a delivery to the previous on…
