Cesarean (C-section), primary

A Cesarean delivery, commonly known as a C-section, refers to a surgical procedure to deliver a baby through an incision in the mother’s abdomen.  The first time a woman has a c-section procedure, it is referred to as a primary c-section.  

Some cesarean sections are necessary to protect the health of the infant or mother.  There are currently no methods to evaluate the “right” number of C-sections for a population of patients.  Some expectant mothers discuss this rate with their obstetricians.

About this measure

This measure tracks the number of primary c-section deliveries per 100 deliveries. It does not include all surgical deliveries. For example, it excludes deliveries of multiple births (twins, triplets, etc.), infants who are in a breech (i.e. feet first) position or surgical deliveries counted in other categories.
