Classification is for “all women” who deliver at a specific setting (e.g. a maternity or a region) and not only for the women who deliver by CS. It is a complete perinatal classification. The classification is simple, robust, reproducible, clinically relevant, and prospective. It allows the comparison and analysis of CS rates within and across these groups of women. Even before official endorsement by an international institution or formal
guidelines recommending its use in 2015, the Robson Classification had been rapidly and increasingly used by many countries all over the world. In 2014 WHO conducted another systematic review to gather the experience of the users of the Robson Classification, to assess the pros and cons of its adoption, implementation and interpretation, and to identify barriers, facilitators and potential adaptations.
