| Popis: | OBJECTIVES Performing and interpreting endovaginal ultrasound is an important skill used during the evaluation of obstetric and gynecologic emergencies. This study aims to describe the level of proficiency and confidence achieved after performing 25 endovaginal examinations. METHODS This is a prospective study at a single urban academic emergency department. Participants performed a minimum of 25 endovaginal ultrasounds under the supervision of a point-of-care ultrasound expert. Anatomical structures were identified by the expert under ultrasound prior to each session. Each examination was scored for agreement of findings between the participant and expert. The data were used to develop a performance curve identifying when proficiency was achieved, where experiential benefit diminished, and when participants felt confident. RESULTS A total of 1117 endovaginal ultrasound examinations were performed by 50 participants. Agreement after 25 examinations was highest (>95%) for probe insertion and preparation, bladder and uterus identification, and directionality. Agreement was lowest for identification of the ovaries (76%). Experiential benefit plateaus occurred earliest (10 exams) for preparation and insertion followed by bladder identification and directionality. Surprisingly, ovarian experiential benefit plateaued at 16 exams. Participant confidence improved overall and was lowest for the identification of ovaries and abnormal pelvic anatomy. CONCLUSIONS There is a significant learning curve when performing endovaginal ultrasound. Our data do not support the use of 25 examinations as a minimum standard for identification of the ovaries or abnormal ovarian pathology. |
