OBJECTIVE:

To evaluate the rates of caesarean section in the termination of pregnancies registered in the private sector of the Obra Social of the province of Buenos Aires (Instituto de Obra Médico Asistencial) between 2017 and 2021.

MATERIALS AND METHODS:

Analytical and descriptive study of caesarean sections registered in the Modulation System of the IOMA Single Audit and Control Centre (CUAFI) of the 13 health regions of the province of Buenos Aires. The percentages of caesarean sections per year and per health region are described.

RESULTS:

75,244 singleton deliveries were registered in the private sector of the Instituto de Obra Médico Asistencial. In 2017, the percentage of caesarean sections increased from 69.0% (12,600 caesarean sections out of 18,258 deliveries) to 73.6% (8,232 caesarean sections out of 11,180 deliveries) in 2021. The highest caesarean section rates were recorded in Region IV (83.6%), Region XIV (81.7%) and Region X (78.9%).

CONCLUSION:

The high percentage of caesarean sections recorded and the increase in recent years shows the need to design interventions to decrease the rate. It is important to have information on the indications for caesarean section and to explore interventions aimed at health personnel and women to reduce the rate.
