Rising C-Section Rates Globally
Over the past few decades, the rate of Caesarean sections (C-sections) has been increasing steadily around the world. According to WHO data, more than 1 in 5 births (about 21 %) are currently by C-section globally, a figure set to increase to nearly 29 % by the year 2030 if current trends continue. The majority of countries far exceed the ideal rate as defined by health experts, at about 10-15 % of births.
When C-Sections are Medically Necessary
C-sections are lifesavers in most circumstances — for example, during fetal distress, abnormal presentation (breech), obstructed labor, placenta previa, or other risk to mother or baby’s health. In such circumstances, surgical delivery reduces risk of morbidity and mortality of both mother and infant.
Risks of Unnecessary C-Sections
When performed without medical necessity, C-sections bring additional risk: increased risk of infection, bleeding, blood clots, increased maternal recovery time, and possible complications in future pregnancies. Elective C-section infants also have an increased risk of respiratory distress and other short-term health problems. The cost is also significant — to families and also to health systems.
Drivers Behind Overuse
Several non-medical reasons appear to be driving rising C-section rates: desire for particular scheduling predictability; concern regarding pain or trouble with vaginal birth; pecuniary incentives in the private sector; family and societal culture expectations; and concerns by providers regarding liability. Wealth, education, use of private hospitals, and media exposure are predictors of non-medically indicated C-sections in high-eve C-section communities.
What Can Be Done?
WHO guidelines recommend non-clinical interventions to reduce unnecessary C-sections: better antenatal counselling; informing women in full; using classifications (e.g. Robson classification) to track and audit C-section rates; second opinions before surgery; and reforming payment models in an effort to reduce financial incentives for surgical birth.
Should the choice for a C-section (in low-risk pregnancies) be limited to strictly medical indications, even if the mother prefers it for non-medical reasons?
