RCOG 2024 – “Do NOT use CTG alone for stillbirth reduction” (STRiDE Findings)
Perfect for PG teaching, OSCE, Insta content (“OBG in a Minute”), and clinical practice.
🔍 Why this update?
The STRiDE Study (Stillbirth Reduction Interventions & Data Evaluation) released new evidence reviewed by RCOG in 2024.
It showed that routine CTG (Cardiotocography) alone does NOT reduce stillbirth rates in low-risk or even many high-risk groups.
⭐ FULL EXPLANATION
1️⃣ CTG is excellent at detecting hypoxia… but terrible at predicting stillbirth
CTG detects current fetal oxygenation, not long-term placental insufficiency.
Stillbirth risk is driven by chronic placental problems like FGR, Doppler abnormalities, maternal disease.
CTG may be normal till very late → so it cannot serve as a screening tool.
2️⃣ STRiDE found: More CTGs = MORE interventions, NOT fewer stillbirths
Routine or frequent CTGs led to:
↑ Emergency LSCS
↑ Instrumental deliveries
↑ Unnecessary inductions
But no significant drop in stillbirth or neonatal morbidity.
Meaning: CTG increases action, not outcomes.
3️⃣ What does reduce stillbirth then?
The STRiDE analysis emphasises multimodal surveillance:
✔ Growth monitoring
Regular symphysio-fundal height
Timely ultrasound growth scans
Customised centiles
Doppler studies
✔ Maternal risk assessment
Hypertensive disease
Diabetes
Smoking/anaemia
Previous stillbirth
Reduced fetal movements
✔ Fetal Doppler studies
Umbilical artery
MCA
CPR (Cerebroplacental ratio)
These detect placental insufficiency, the MOST important stillbirth predictor.
✔ Timely delivery decisions
Deciding when to deliver a compromised fetus is more important than CTG frequency.
4️⃣ CTG should ONLY be used for what it is intended for
✔ Intrapartum monitoring
During labour in appropriate risk groups.
✔ Acute assessment
If reduced fetal movements / decelerations / suspected acute hypoxia.
Not for routine antenatal screening.
5️⃣ RCOG 2024 Key Message
**“CTG ALONE cannot reduce stillbirth.
Use integrated surveillance instead.”**
This means CTG must be part of a package—not the package itself.
