Cesarean delivery in a tertiary institution of the Republic of Moldova: analysis using the Robson classification.

BACKGROUND

The worldwide increase in the cesarean delivery rate is a major public health concern and cause of significant debate. Although multiple studies have shown that higher cesarean delivery rates may be associated with adverse maternal and perinatal outcomes, the number of cesarean deliveries has been continuously increasing. In the Republic of Moldova, cesarean delivery increased from 15.75% in 2012 to 27.42% in 2022. However, the perinatal mortality remained unchanged at 11.6%. To understand the factors that determine the increasing trend in cesarean delivery and to approach new strategies to reduce unnecessary surgical delivery, a standardized tool is needed to assess and compare cesarean delivery rates.

OBJECTIVE

This study aimed to assess the changes in the rates and trends of cesarean delivery and to evaluate the contribution of different obstetrical populations to overall cesarean delivery rates in the Municipal Clinical Hospital using the Robson classification.

STUDY DESIGN

This was a cohort study conducted at the Municipal Clinical Hospital in Chisinau. The study included 13,882 women who gave birth in 2017, 2019, and 2022 at the Municipal Clinical Hospital. All births were classified into 10 Robson groups, using 6 basic variables (parity, cesarean delivery in medical history, labor onset, number of fetuses, gestational age, and fetal presentation). Statistical data were collected and analyzed using the Epi Info program (version 7.2.1.0; Centers for Disease Control and Prevention, Atlanta, GA).

RESULTS

The overall cesarean delivery rate was 20.02% (2779/13,882), with a significant increase from 18.59% (809/4351) to 21.59% (1134/5252) (=.0003). Approximately one-third (1099/2279 [39.55%]) of all cesarean deliveries were performed before labor onset. The main contributor in all study years was group 5 (957/2779 [34.44%]). The next valuable group that contributed to the overall cesarean delivery rate was group 2 (393/2779 [14.14%]), followed by group 1 (333/2779 [11.98%]).

CONCLUSION

The Robson Ten-Group Classification System provides a clear and detailed record of the trends in cesarean delivery. In addition, because of the Robson Ten-Group Classification System's simplicity and exclusivity, it can be implemented in the Republic of Moldova. The main contributors to the overall cesarean delivery rate were women with a previous cesarean delivery (group 5), followed by nulliparous women of group 2 and group 1.
