Summary:
Globally, the proportion of Cesarean sections (CS) has been steadily increasing over the past decades, while the proportion of vaginal births has been declining. The World Health Organisation (WHO) emphasises that CS is a life-saving procedure for both mother and child, only when there is a clear medical indication. The other option for operative intervention is operative vaiganl delivery (OVD). All operative deliveries carry a risk of short- and long-term complications for both mother and child. The WHO recommends the use of the Robson Classification System as a global standard for the consistent evaluation and development of obstetric care. This system enables the objective assessment, monitoring, and comparison of CS rates across healthcare facilities, both nationally and globally, and can also be applied to evaluating operative vaginal delivery. In addition to CS, the proportion of operative vaginal deliveries should also be monitored.
Estonia and Finland are neighbouring countries, but their perinatal indicators have historically been very different. This study provides an opportunity to compare and analyse the proportions and time trends of operative deliveries over three decades in Estonia and Finland.
The proportions of CS and OVD have increased over the study period in both countries. As of 2023, the CS rates in Estonia and Finland are similar to the global average (21%). In many other European countries, however, the proportion of CS is significantly higher. Based on the results of the Robson Classification System, Estonia is similar to the Nordic countries, including Finland. The proportion of OVD in Finland has consistently been about twice as high as in Estonia throughout the study period. Vacuum extraction has become the only method of operative vaginal delivery in both countries, as in many other European countries. By the end of the study period, operative deliveries accounted for approximately a quarter of all births in Estonia and Finland.
