Development and validation of a clinical prediction model for postpartum hemorrhage after elective cesarean section

Key Points

• Postpartum hemorrhage risk increases significantly after elective cesarean section, with certain factors identified.
• The clinical prediction model achieved an area under the curve of 0.85, indicating good accuracy in identifying at-risk patients.
• Validation of the model was conducted using data from multiple hospitals to ensure reliability across different settings.
• Implications of this model support better management of postpartum hemorrhage, aiming for safer cesarean deliveries.
