University of Southern California·interventional·Posted Feb 17, 2021·Updated Oct 7, 2025

In Brief

A clinical study evaluating Overdose Notification for Opioid Abuse. Completed, enrolled 61 participants across 1 site.

Detailed Summary

The opioid epidemic is the largest man-made public health crisis the United States has faced. The objective of Trial 2 of the Application of Economics \& Social psychology to improve Opioid Prescribing Safety (AESOPS-2) study, is to discourage unnecessary opioid prescribing by increasing the salience of negative patient outcomes associated with opioid use.

Interventions

Overdose Notificationbehavioral

We will identify overdoses from state vital records and insurance claims data linked to emergency departments. We will use electronic health record data to identify prescriptions of scheduled drug to patients who experienced a non-fatal or fatal overdose within the health system. If randomized to the overdose notification group, physicians who prescribed the controlled substances to the deceased or surviving patient in the year prior to their overdose will be informed of the overdose via letter. The letters will alert prescribers to the patient's opioid-related overdose, recommend the use of the state-level PDMP, and list evidence-based interventions to lower opioid-related overdoses. The letters will increase the salience and availability of opioid-related harms, which may cause clinicians to be more wary of a future overdose when prescribing opioids, benzodiazepines, muscle relaxants, or sedative-hypnotics.
