RESUMO
While cesarean deliveries performed for health indications can save lives, unnecessary cesareans cause unjustifiable health risks for the mother, newborn, and for future pregnancies. Previous recommendations for cesarean delivery rates at a country level in the 10-15% range are currently unrealistic, and the proposed concept that striving to achieve specific rates is not important has resulted in a confusing message reaching healthcare professionals and the public. It is important to have a clear understanding of when cesarean delivery rates are deviating from internationally acceptable ranges, to trigger the implementation of healthcare policies needed to correct this problem. Based on currently existing scientific evidence, we recommend that cesarean delivery rates at a country level should be in the 15-20% range. This advice is based on the demonstration of decreased maternal and neonatal mortalities when national cesarean delivery rates rise to circa 15%, but values exceeding 20% are not associated with further benefits. It is also based on real-world experiences from northern European countries, where cesarean delivery rates in the 15-20% range are associated with some of the best maternal and perinatal quality indicators in the world. With the increase in cesarean delivery rates projected for the coming years, experience in provision of intrapartum care may come under threat in many hospitals, and recovering from this situation is likely to be a major challenge. Professional and scientific societies, together with healthcare authorities and governments need to prioritize actions to reverse the upward trend in cesarean delivery rates observed in many countries, and to strive to achieve values as close as possible to the recommended range.
