Robson Ten-Group Classification Study of Cesarean Section Rates in Assiut Hospitals

Cesarean section (C-section) rates have risen dramatically worldwide, with Egypt showing one of the fastest increases, from 4.6% in 1992 to nearly 52% in 2014. Current national data indicate a rate of 51.8%, placing Egypt among the top three countries globally in C-section prevalence. This upward trend highlights an urgent need for systematic evaluation and targeted interventions.

In 2015, the World Health Organization (WHO) endorsed the Robson Ten Group Classification System (TGCS) as the international standard for assessing, monitoring, and comparing cesarean section rates. The TGCS categorizes all women into ten mutually exclusive and totally inclusive groups based on five basic obstetric characteristics: parity, previous cesarean section, onset of labor, gestational age, and fetal presentation. This approach allows for meaningful comparisons within and across institutions, identification of the main contributors to cesarean rates, and evaluation of adherence to evidence-based clinical practice.

Studies worldwide consistently report that Groups 5 (previous cesarean, single cephalic, ≥37 weeks), 2 (nulliparous, induced or elective), and 1 (nulliparous, spontaneous labor) are the major contributors to rising C-section rates. In Egypt, substantial variation exists across hospitals, with facility-specific C-section rates ranging from 22.9% to 94.3%. Previous studies at Assiut University Hospital showed an increase from 32% in 2008 to 38% in 2011, yet comparative analyses across different institutions remain scarce.

This prospective cross-sectional survey will be conducted between January and December 2026 in Assiut University Hospital and Assiut General Hospital. All women delivering by cesarean section during the study period will be eligible, with exclusion of incomplete medical records or deliveries before 28 weeks. The estimated sample size is 770 cases, accounting for incomplete records. Data will be extracted using a standardized Robson-based form and entered electronically.

Primary outcomes include:

Distribution of cesarean deliveries across Robson groups

Comparison of C-section rates within Robson groups between hospitals

Contribution of each Robson group to the overall C-section rate

Secondary outcomes include:

Maternal outcomes (mortality, complications, ICU admission, postpartum hemorrhage, length of stay)

Neonatal outcomes (birth weight, Apgar score, NICU admission, perinatal complications)

Analysis of C-section indications within Robson groups

Identification of potentially avoidable cesarean deliveries

Assessment of adherence to clinical guidelines

Data analysis will be performed using SPSS v29.0. Statistical methods include descriptive analysis, chi-square tests, Fisher's exact tests, t-tests, logistic regression, and propensity score matching. A p-value <0.05 will be considered significant.

The results of this study will provide evidence on institutional differences in cesarean section practices in Assiut, inform local health policies, and support interventions aimed at optimizing the use of cesarean delivery to improve maternal and neonatal outcomes.
