Clinical Scorecard: Creation and assessment of a predictive framework for identifying the risk of forceps delivery in term singleton first-time mothers to enhance early detection and labor management strategies.

At a Glance

CategoryDetail
ConditionForceps-assisted delivery in term singleton primiparas
Key MechanismsPredictive model based on maternal and fetal characteristics at the onset of the second stage of labor
Target PopulationTerm singleton primiparas
Care SettingIntrapartum care in a hospital setting

Key Highlights

  • Independent risk factors for forceps delivery include BMI ≥ 28 kg/m2, fetal abdominal circumference ≥ 340 mm, grade II or III meconium-stained fluid, non-occipital anterior fetal position, and active phase duration ≥ 120 min.
  • The predictive model achieved an AUC of 0.775, indicating good discrimination.
  • The model demonstrated acceptable calibration and provided a net benefit over the treat-all strategy for clinically plausible threshold probabilities up to 0.35.
  • The study emphasizes the importance of early risk identification to optimize intrapartum management.
  • Further prospective validation is warranted to assess real-world clinical impact.

Guideline-Based Recommendations

Diagnosis

  • Utilize the predictive model to identify high-risk cases of forceps delivery at the onset of the second stage of labor.

Management

  • Implement targeted intrapartum care strategies based on identified risk factors.

Monitoring & Follow-up

  • Continuously assess maternal and fetal characteristics during labor to inform decision-making.

Risks

  • Be aware of the maternal and neonatal risks associated with prolonged labor and forceps delivery.

Patient & Prescribing Data

Early identification of high-risk mothers can facilitate timely mobilization of qualified operators and neonatal support.

Clinical Best Practices

  • Adopt standardized protocols for forceps-assisted delivery.
  • Ensure experienced obstetricians confirm indications for assisted vaginal delivery.
  • Utilize objective risk assessment tools to guide clinical decision-making.
