Predictive modeling of labor epidural catheter replacement or conversion to spinal or general anesthesia: a multicenter retrospective cohort study (2017–2024)
Authors' conclusion
We developed and externally validated Risk Estimation for Anesthesia Catheter Technique replacement or conversion in Obstetrics (REACT-OB) to estimate the risk of this outcome.
Study context
- Population
- Patients receiving labor epidural analgesia (standard epidural or dural puncture epidural) in a large multihospital healthcare system, 2017–202482,823 catheter placements
- Participants
- 65,419 patients
- Exposure
- Logistic regression vs XGBoost prediction models
- Outcome
- Composite of:
- Epidural catheter replacement
- Subsequent spinal anesthesia
- Advanced airway placement indicating GA for cesarean delivery within the same anesthesia encounter
Methodological detailsmulticentre, prediction model development, external validation (one hospital held out)

- 5010 (6.0%)
Observational data: associations, not effects.
Further findings
Important predictors
- Prior replacement or conversion during same encounter, end-of-pregnancy BMI, pre-placement pain score, prior cesarean delivery, parity, delivery hospital
Decision-curve analysis and Monte Carlo simulation
- Possible utility for screening and triage when anesthesia staffing is limited
