A Randomized Prospective Analysis of Time to Diagnosis and Length of Stay of Emergency Department Pelvic Ultrasonography

Not Applicable

Completed

• Conditions: Pregnancy

• Registration Number: NCT02268877
• Lead Sponsor: Denver Health and Hospital Authority

Brief Summary

The goal of this project is to compare the efficiency of pelvic ultrasounds performed by emergency medicine residents and attending physicians to the efficiency of pelvic ultrasounds performed by the department of radiology.

Detailed Description

This study is a randomized, prospective interventional study of pregnant patients presenting to the emergency department with complaints of pelvic pain and/or vaginal bleeding. This study will be conducted at 4 sites across the United States. Patients who are eligible and consent to participate will be randomized to one of two conditions; 1) a pelvic ultrasound that is performed by a certified emergency department attending or physician, or 2) a pelvic ultrasound that is performed by a certified radiology technician (standard-of-care). The time to diagnosis and emergency department length of stay between the two groups will be compared.
