Study Summary

Intravenous opioids are the mainstay of acute, severe pain treatment in Emergency Departments (ED) across the country. Acetaminophen, given orally, has also been used for treatment of mild to moderate pain. The more potent intravenous (IV) form of acetaminophen has been widely used in Europe for more than 20 years as post-surgical analgesia and received full FDA approval in the USA in 2010. As part of a continuing set of studies whose goal is to optimize treatment of pain among elderly ED patients, this randomized study will compare efficacy and safety of IV acetaminophen to IV hydromorphone.

Primary Outcome

Pain improvement was assessed using an NRS (numeric rating scale) to assess pain on a range of 0-10. Participants were asked to verbalize intensity of pain on the scale with zero meaning "no pain" and 10 meaning "the worst pain imaginable." Pain was assessed at baseline and 60 minutes later to determine if clinically important improvement in pain was achieved. Clinically important improvement in pain was defined as an improvement of \>=1.3 points on the 0-10 scale.
