Summary
SisPorto, an automated cardiotocogram analysis program, shows promising results in predicting poor neonatal outcomes with high accuracy. Its expert-level agreement in analyzing fetal heart rate tracings supports its clinical potential.
Area of Science:
- Obstetrics and Gynecology
- Medical Informatics
- Fetal Monitoring
Background:
- Cardiotocography (CTG) is crucial for fetal well-being assessment.
- Automated analysis of CTG can improve diagnostic accuracy and efficiency.
- Existing systems may have limitations in guideline adherence or signal processing.
Purpose of the Study:
- To present the latest version of the SisPorto software for automated cardiotocogram analysis.
- To detail its adherence to FIGO guidelines and its capabilities for antepartum and intrapartum analysis.
- To highlight its features, including no signal reduction and twin recording.
Main Methods:
- Detailed description of SisPorto's processing algorithms and operational procedures.
- Evaluation of SisPorto's performance through comparative studies with expert analysis.
- Validation studies assessing its predictive accuracy for neonatal outcomes.
Main Results:
- SisPorto tested in over 6000 pregnancies, demonstrating reliable Fetal Heart Rate (FHR) baseline estimation (within 8 bpm of experts).
- Good agreement (0.64-0.89) with expert identification of accelerations, decelerations, contractions, and variability.
- High sensitivity (100%) and specificity (99%) in predicting poor neonatal outcomes in a preliminary study.
Conclusions:
- SisPorto, while research-level, has extensive testing and gathered considerable experience.
- The system shows promising results in comparison with expert analyses.
- Its validity in predicting adverse neonatal outcomes is strong, warranting further international validation.
