Robson App

A calculator that allows to classify pregnant woman according to Robson classification, recommended by the WHO.

Since 2015, the WHO recommends the use of the Robson Classification to be used worldwide to assess, monitor and compare caesarean section (CS) rates over time in a same hospital or between different hospitals.

The Robson classification categorizes all women into one of 10 groups that are mutually exclusive and, as a set, totally comprehensive. The groups are based on 5 basic obstetric characteristics that are routinely collected in all maternities:

1. Parity
2. Number of foetuses
3. Foetal lie and presentation
4. Gestational age
5. Onset of labour

The classification is simple, robust, reproducible, clinically relevant, and prospective – which means that every woman admitted for delivery can be immediately classified into one of the 10 groups based on these few basic characteristics. This allows a comparison and analysis of caesarean section rates within and across these groups.
