Predictors of pain relief and adverse events in patients receiving opioids in a prehospital setting.

Objective: The aim of the study was to analyze factors predicting pain relief and adverse events in patients receiving opioids for acute pain in a prehospital setting.

Methods: In this prospective, observational clinical study, adult patients with a numerical rating scale (NRS) score of 5 of 10 or higher who required treatment with intravenous opioids for pain control were included. The primary outcome variable was final analgesia defined by an NRS score of 3 of 10 or lower upon arrival to the emergency department.
