In the WHO classification of indications for cesarean section, what is the WHO's position on the 'optimal' CS rate at a population level (2015 statement)?
- A CS rates between 10–15% are associated with fewer maternal and neonatal deaths; above 15% confers no additional benefit ✓
- B There is no evidence of benefit from CS rates above 10%; the ideal rate is below 5%
- C CS rates should be at least 25% to capture complex deliveries in low-resource settings
- D Any CS rate between 5–30% is acceptable depending on maternal age distribution
Correct answer: A. CS rates between 10–15% are associated with fewer maternal and neonatal deaths; above 15% confers no additional benefit
Explanation
The WHO 2015 statement concluded that CS rates between 10–15% at the population level are associated with lower maternal and perinatal mortality. Below 10%, under-use of CS leads to preventable deaths; above 15%, evidence does not show additional population-level mortality benefit and may be associated with harm. This replaced the older 'ideal 15%' figure and shifted the focus from a target rate to ensuring CS is performed when medically indicated.
