Robson classification of caesarean sections in two Polish centres on different levels of reference

Introduction
Caesarean section (CS) is one of the most common abdominal surgeries performed in the world. The 10-Group Classification System (TGCS, Robson classification) is a World Health Organization recommended classification assessing indications based on 5 variables (parity, previous caesarean section, labour onset, foetal presentation, gestational age, and number of fetuses). The TGCS provides the opportunity to compare indications between different countries, audit, and evaluate of the quality and impact of the recommendations. Aim of the research: Classification of CS data derived from 2 centres according to the TGCS.

Material and methods
We used the above-mentioned tool to classify 2000 Caesarean sections from two centres – II and III degree of reference.

Results
In both groups, group 5 (RG5 – Robson group 5) constituted the largest part of all Caesarean sections, at 39.9% and 35.17%, respectively. The sum of groups from 1 to 4 (RG 1–4) had a relative contribution to the total number of Caesarean sections in individual centres of 46.94% and 53.48%, respectively. The percentage of occurrence of particular classes was similar in both centres.

Conclusions
The results of our study are an attempt to determine the trend in indications for Caesarean sections according to the TGCS in Poland and to popularize the tool used according to WHO recommendations. All activities aimed at effective reduction of the number of Caesarean sections in Poland should be aimed primarily at reducing the percentage of Caesarean sections in the RG5 group.
