Trial Outcomes & Findings for Emergency Department (ED) Drug Interaction in Emergency Department Patients (NCT NCT01859715)

NCT ID: NCT01859715

Last Updated: 2016-05-05

Results Overview

Clinically significant visual analogue scale (VAS; a measure of adult pain and nausea on a scale of 1-100 millimeters for increasing symptoms of pain and nausea) for patients who were administered either oxycodone, hydrocodone/acetaminophen, or ondansetron in the ED. Clinically significant change was defined as 13mm change on the VAS from baseline (when first VAS was completed) to 90 minutes following drug administration in the ED.

Participant Flow

Recruitment was initiated in the University of Colorado Hospital ED. A convenience sample sample of ED patients were enrolled between June 2012 to January 2013. Subjects were included if they had self-reported pain or nausea identified during the initial nursing assessment. The previous 2 day medication history was obtained during their visit.

201/502 consented patients did not receive the study medication. The remaining 301 patients were allocated to either one of the opioid treatment groups or the nausea observational group based on what study medication they were prescribed and if they were able to complete serial visual analog scales for pain and nausea.
