Robson Ten Group Classification System

The Robson Ten Group Classification System (TGCS) is a classification system by which all perinatal events and outcomes can be compared. The system classifies all pregnant women into one of ten groups, each of which are mutually exclusive and, as a set, comprehensive.

The groups are based on five basic obstetric characteristics that are routinely collected for all maternities: parity, onset of labour, gestational age, foetal presentation and number of foetuses.

The classification is simple, robust, reproducible, clinically relevant, and prospective; this means that every woman admitted for delivery can be immediately classified into one of the groups based on these few basic characteristics. The Robson TGCS can be used to analyse all labour events and outcomes and significant epidemiological variables can be considered.

This system has been used extensively internationally to analyse caesarean deliveries. In 2015, the World Health Organization (WHO) endorsed the Robson TGCS as the global standard for assessing, monitoring, and comparing CS rates within and between healthcare facilities over time.

In Ireland, The Robson TGCS has been endorsed by the Institute of Obstetricians and Gynaecologists and the Health Service Executive Clinical Care Programme in Obstetrics and Gynaecology.
