Objectives:
This study aimed to describe the trends in cesarean delivery (CD) rates in Ontario using the modified Robson classification system, and identify the most common indications for CD.
Methods:
We conducted a population-based retrospective cross-sectional study using data from the Better Outcomes Registry & Network, a comprehensive maternal-child registry in Ontario. The analysis included all pregnant persons who delivered a live- or stillborn infant weighing ≥500 g at ≥200 weeks gestation between April 1, 2012 and March 31, 2019.
Results:
A total of 952 567 pregnant persons gave birth in Ontario, Canada, during the study period. Our findings demonstrated a slight increase in the overall CD rate over 7 fiscal years from 2012-2013 to 2018-2019. Robson group 5 (term, singleton, cephalic pregnancy with previous CD), groups 1 and 2 (nulliparous, term, singleton, cephalic pregnancy and no labour, induced labour, or spontaneous labour), and group 6 (nulliparous pregnancy with breech presentation) made the largest contributions to the overall CD rate over the study period. The top 5 primary indications for CD across all years included previous CD, atypical or abnormal fetal surveillance, malposition/malpresentation, non-progressive first stage of labour, and non-progressive second stage of labour.
Conclusions:
The results enhance our understanding of the key drivers of CD rates. These findings will help to inform practice improvement, support policy change, and identify areas where future research is needed.
