Area of Science:

  • Obstetrics and Gynecology
  • Medical Education
  • Diagnostic Imaging

Background:

  • Accurate cervical length measurement via transvaginal ultrasound is crucial for assessing preterm labor risk.
  • Resident competency in this skill can vary and may benefit from structured training.

Purpose of the Study:

  • To evaluate the effectiveness of a structured teaching module in improving resident proficiency in transvaginal sonographic cervical length measurements.

Main Methods:

  • A prospective cohort study involved obstetrics and gynecology residents performing cervical length measurements.
  • Residents underwent a lecture-based teaching module with pre- and post-intervention assessments and image collection.
  • Images were independently scored by Maternal-Fetal Medicine specialists for quality and accuracy.

Main Results:

  • Most residents (93%) improved or maintained perfect scores on assessments post-module (p<0.01).
  • Seventy-nine percent of residents showed improved cervical image scores after the educational session.
  • Mean resident scores increased significantly from 73.7 pre-intervention to 90.2 post-intervention (p<0.01).

Conclusions:

  • Implementing a structured educational module demonstrably enhances resident competence in transvaginal ultrasound cervical length measurements.
  • This training approach is effective for improving diagnostic accuracy in managing threatened preterm labor.
