Summary
This summary is machine-generated.

A review of seven external cephalic version (ECV) prediction models found only one with external validation and acceptable performance. This model, identifying key predictors like parity and placental location, is recommended for counseling women considering ECV.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Medicine
  • Clinical Prediction Modeling

Background:

  • External cephalic version (ECV) is a procedure to turn a fetus from breech to cephalic presentation.
  • Accurate prediction of ECV success is crucial for patient counseling and clinical decision-making.
  • Existing prediction models for ECV success require thorough evaluation of their development and performance.

Purpose of the Study:

  • To provide an overview of existing prediction models for successful ECV.
  • To assess the quality, development, and performance of these models.
  • To identify key predictor variables for successful ECV.

Main Methods:

  • Systematic literature search of MEDLINE, EMBASE, and Cochrane Library up to January 2015.
  • Extraction of data on study design, sample size, model-building, and validation.
  • Evaluation of model development phases, performance (discrimination, calibration), and predictor variables.

Main Results:

  • Seven prediction models were identified across eight articles; all underwent internal validation.
  • Only one model was externally validated and demonstrated promising predictive performance (AUC 0.71 internal, 0.64 external).
  • Key predictors included parity, placental location, breech engagement, and fetal head palpability. No models evaluated clinical impact.

Conclusions:

  • One prediction model for ECV success in breech presentation is validated externally with acceptable performance.
  • This validated model, considering factors like parity and placental location, should be utilized for counseling women undergoing ECV.
  • Further research is needed to assess the clinical utility and impact of ECV prediction models.
