Official title
Is Transabdominal Sonography Comparable to Transvaginal Sonography for Eligibility Assessment Prior to Medical Abortion? A Randomized Controlled Trial.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigator will perform a multicenter, randomized controlled trial in practices that routinely use transvaginal sonography (TVS) to compare how often clinicians order additional testing prior to medical abortion after the use of either TVS or transabdominal ultrasound (TAS) in medical abortion eligibility assessment. Women will be randomized to receive either TVS or TAS prior to medical abortion. We anticipate enrolling 800 patients receiving care from about 30 providers over 6-8 months. The primary study outcome will be the proportion of women that requires additional evaluation after sonography, prior to determination of medical abortion eligibility. The second primary outcome will be patient satisfaction, determined by a patient satisfaction questionnaire utilizing a visual analog scale.
