摘要
Objectives-Transvaginal sonographic cervical length screening is an important tool for the evaluation of preterm labor. However, a structured curriculum is lacking in obstetrics and gynecology residency programs. The Accurate Cervical Evaluation with Sonography (ACES) program was developed to address this deficiency and combines an online didactic course with a standardized performance assessment of live scans. We sought to evaluate the effectiveness of the ACES program to teach residents sonographic cervical length assessment. Methods-All obstetrics and gynecology residents at our institution were invited to participate from 2012 to 2013. The program consisted of an initial supervised transvaginal cervical evaluation, an online didactic course and written examination, and 5 subsequent supervised scans. The instructor performed an independent cervical length measurement at each encounter. The primary outcome was the difference in cervical length measurement between the resident and instructor. We hypothesized that this difference would decrease over time. At each visit, a 10-item checklist was used for skill assessment. Comparisons of checklist scores over time were also performed. Results-Seventeen of 20 residents completed at least some of the training, and 10 completed the entire program. The median difference in cervical length measurement between residents and instructors at posttests 3, 4, and 5 improved significantly compared to the pretest scan (all P = .02). Similarly, the checklist scores improved over time (all P = .0008). Conclusions-Transvaginal cervical sonography is an important tool in the evaluation of preterm labor. The ACES program provides residents a structured curriculum for cervical evaluation and supervisors a standardized means of evaluating trainees' skills.
