Summary
A new classification system for caesarean sections was developed and validated. This four-grade system, based on clinical definitions, showed high agreement between obstetricians and anaesthetists for improved maternity data collection.
Area of Science:
- Obstetrics and Gynecology
- Anesthesiology
- Medical Classification Systems
Background:
- Caesarean section classification lacks standardization, impacting data collection and clinical decision-making.
- Existing methods for classifying caesarean sections show variability in consistency and utility.
Purpose of the Study:
- To develop and validate a new, consistent classification system for caesarean sections.
- To improve the reliability of data collection for caesarean sections through a standardized classification.
Main Methods:
- A two-part study involving 90 anaesthetists and obstetricians grading clinical scenarios using five classification methods.
- Prospective application of the most effective method (clinical definitions) to 407 caesarean sections across six hospitals.
Main Results:
- Clinical definitions emerged as the most consistent and useful classification method.
- High agreement (86-90%) was observed between anaesthetists and obstetricians using the developed five-point and four-grade scales.
Conclusions:
- A novel four-grade caesarean section classification system based on clinical definitions is proposed.
- The proposed system demonstrates strong inter-rater reliability and is recommended for adoption by maternity data collection groups.
