Caesarean births - Robson classification


    Caesarean section births by Robson classification groups, ACT mothers, 2007-2009 to 2019-2021

    The World Health Organization (WHO) previously recommended a population caesarean section rate of 10–15% to ensure mortality rates are kept low for mothers and babies.1 However in 2015, the WHO guidelines were revised. Caesarean section rates at population level can be determined by the type of hospital(s) in that particular area, for example, larger hospitals tend to receive referrals of most complicated pregnancies or deliveries which in turn, may need more caesarean sections. On the other hand, some small facilities may not even be equipped to conduct caesarean sections.2 The WHO recommends that, rather than a population-based estimate of caesarean section rate, the Robson classification (also called the 10-group classification) be used to evaluate and compare caesarean section rates between groups of women.1 3 The Robson classification allows the comparison of caesarean section rates amount births with similar clinical characteristics. This classification system groups women into 10 mutually exclusive groups based on obstetric characteristics, such as parity (number of previous pregnancies), onset of labour, whether there has been a previous caesarean section, and the baby’s gestational age.
