Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Change in Daily Average Number of 5 MME Pill Counts

    The primary outcome is the change in daily average number of 5 morphine milligram equivalent (MME) pill counts ordered by clinicians during the last week of baseline (week 26) and the last week of the intervention period (week 53) letter intervention.

    13 months (6 months pre-intervention, 30-day washout period, 6 months post-intervention)

Secondary Outcomes (1)

  • Change in Clinician-level, Pre-to-post Mean Proportion of High Dose (=> 50 MME) Patient Visits

    13 months (6 months pre-intervention, 30-day washout period, 6 months post-intervention)

Study Arms (2)

Control Group

NO INTERVENTION

Physicians in the control group will receive no notification of their patient's fatal or nonfatal overdose.

Overdose Notification Group

EXPERIMENTAL

The overdose notifications 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.

Behavioral: Overdose Notification

Interventions

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.
