EP11.18: Analysis of Caesarean section at the University of Benin Teaching Hospital using Robson 10‐group classification system

To analyse Caesarean sections (CS) at the University of Benin Teaching Hospital over a one year period using the Robson 10 group classification system. This was an observational retrospective study carried out at the University of Benin Teaching Hospital (UBTH), Benin City, Edo State, Nigeria. All women who gave birth at UBTH from January 1st 2020 to December 31st 2020 were studied. Ethical approval for the study was obtained with approval number: ADM/E 22/A/VOL. VII/14301121005. The CS rate during the period of this study was 45.8%. Using the Robson classification system the highest group of women that delivered during the period was group 3 (multiparous [excluding previous CS], single cephalic fetus, >/37weeks in spontaneous labour), followed by Group 5 (all multiparous with at least 1 previous CS, single cephalic fetus, >/37weeks) and Group 4 (multiparous (excluding previous CS), single cephalic, >/37weeks, induced or prelabour CS). Highest contributing group to CS rate were Group 5 with a relative group contribution of 32% followed by Group 2 (nulliparous, single cephalic fetus, >/37weeks, induced or prelabour CS) with a relative group contribution of 14% and Group10 (all women with a single cephalic pregnancy, <37 weeks including women with previous CS(s)) with a relative group contribution of 11.7%. Groups 8 (all women with multiple pregnancies including women with previous CS(s)), 10 and 7 (all multiparous women with a singleton breech pregnancy including women with previous CS(s)) had the highest contribution to still birth and babies with 5th minute APGAR less than 7. The finding from this study indicates a high CS rate in UBTH with Robson Groups 5, 10 and 2 accounting for a large percentage of the CS rate in the study period. Effort should be targeted at reducing primary CS rate to the barest minimum. The trend of increasing utilization of CS for indications that are not purely obstetrics such as maternal request should be discouraged.
