Pre-ultrasound assessment: After eligibility is determined, a research associate will approach the provider directly involved in the patient's care (Resident or Staff). The provider completing the data collection forms does not need to be the provider who ordered or performed the ultrasound. The provider completing the forms will be an Emergency Medicine 2nd year level resident or above. The provider filling out the data collection form will fill out the pre-ultrasound assessment prior to reviewing the cardiac ultrasound images (either in real-time or on the computer after the ultrasound is completed). The provider will fill out a data collection form that asks about the most likely diagnosis, expected ultrasound findings, and current management plan.
