Application of Economics & Social Psychology to Improve Opioid Prescribing Safety Trial 1: Electronic Health Record Nudges

The opioid epidemic has had a tremendous negative impact on the health of persons in the U.S. The objective of the trial 1 of Application of Economics & Social psychology to improve Opioid Prescribing Safety (AESOPS-T1), is to discourage unnecessary opioid prescribing through the application of "behavioral insights"-empirically-tested social and psychological interventions that affect choice.

Study Overview

Detailed Description

A multisite study, AESOPS-T1 randomizes clinics to behavioral intervention or control. Clinics randomized to the behavioral intervention arm receive electronic health record (EHR)-based nudges. Eligible participants are clinicians who practice ambulatory primary care at the participating clinical sites in Illinois and California. At the time of opioid prescribing, clinicians in clinics randomized to the intervention group will be prompted with an EHR nudge when the prescribing history for the patient falls into one of the following three mutually exclusive categories: Opioid naïve, At-risk for long-term use, or Long-term opioid recipient. These EHR-based nudges include accountable justification, defaults and precommitments. The control arm receives no EHR-based intervention. Both arms receive guideline education. The primary outcome is the change in clinician aggregate weekly milligram morphine equivalent (MME) dose and the secondary outcome is the proportion of dosages that equal or exceed 50 MME per day. These outcomes will be estimated by treatment arm with an intent-to-treat difference-in-differences framework using a mixed-effects regression model on clinician MME daily dose. The intervention period will be 18-months, with a 6-month follow-up period to measure the persistence of effects after the interventions conclude.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Behavioral Intervention Arm
Clinicians in clinics randomized to the intervention group will be prompted with an EHR nudge when the prescribing history for the patient falls into one of the following three categories: Opioid naïve, At-risk for long-term use, or Long-term opioid recipient. These EHR-based nudges include elements of accountable justification, defaults and precommitments. Clinicians will also receive web-based guideline education, consisting of an online educational module at the start of the study period. This will include educational clinical content related to the CDC guidelines, the Oregon Pain Guidance document, tapering training and other resources such as Substance Abuse and Mental Health Services Administration (SAMHSA) Medication-Assisted Treatment Physician Locator and the Naloxone Provider Guide.
Visits where the order is for an included opioid and there is no prior opioid prescription with a start date of greater than 1 day and less than 91 days and clinician is on the clinic list as a treating member of the clinic
Visit where the order is for an included opioid, there is a prior opioid prescription with a start date greater than 1 day and less than 91 days, and there is no prior opioid prescription with a start date greater than 90 days and clinician is on the clinic list as a treating member of the clinic
Total opioid doses are at least 50 MME per day, there are two or more prior opioid prescriptions with two different start dates both greater than 1 day and less than 91 days, and there is a prior opioid prescription with a start date greater than 90 days and less than 181 days and clinician is on the clinic list as a treating member of the clinic
No Intervention: Control
Clinicians in clinics randomized to the control group will receive web-based guideline education, consisting of an online educational module at the start of the study period. This will include educational clinical content related to the CDC guidelines, the Oregon Pain Guidance document, tapering training and other resources such as Substance Abuse and Mental Health Services Administration (SAMHSA) Medication-Assisted Treatment Physician Locator and the Naloxone Provider Guide.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Average Per-clinician Log Total Weekly MME Between Baseline and Intervention for Opioid Naïve and At-Risk Patients (Below 50 MME Daily Dose Rxs)
Time Frame: 6-month baseline and 18-month intervention
Change = (18-month intervention average of natural log MME summed per-clinician, per-week - 6-month baseline average of natural log MME summed per-clinician, per-week). Log(total MME) = log(Rx strength x number of pills x opioid conversion factor)
6-month baseline and 18-month intervention
Change in Average Per-clinician Log Total Weekly MME Between Baseline and Intervention for Chronic Opioid Patients (=> 50 MME Daily Dose Rxs)
Time Frame: 6-month baseline and 18-month intervention
Change = (18-month intervention average of natural log MME summed per-clinician, per-week - 6-month baseline average of natural log MME summed per-clinician, per-week). Log(total MME) = log(Rx strength x number of pills x opioid conversion factor)
6-month baseline and 18-month intervention

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Average Per-clinician Weekly Proportion of Chronic Patients Prescribed a High Dose Opioid (=> 50 MME Daily Dose Rxs) Between Baseline and Intervention
Time Frame: 6-month baseline and 18-month intervention
Change = (18-month intervention average per-clinician weekly proportion - 6-month baseline average per-clinician weekly proportion). Proportion = number of chronic patients who received Rx => 50 MME per-clinician, per-week/total patients who received opioid Rx per-clinician, per-week
6-month baseline and 18-month intervention

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Average Per-clinician Log Total Weekly MME Between Baseline and Post-intervention for Opioid Naïve and At-Risk Patients (Below 50 MME Daily Dose Rxs)
Time Frame: 6-month baseline and 6-month post-intervention
Change = (6-month post-intervention average of natural log MME summed per-clinician, per-week - the 18-month baseline average of natural log MME summed per-clinician, per-week). Log(total MME) = log(Rx strength x number of pills x opioid conversion factor)
6-month baseline and 6-month post-intervention
Change in Average Per-clinician Weekly Proportion of Chronic Patients Prescribed a High Dose Opioid (=> 50 MME Daily Dose Rxs) Between Baseline and Post-intervention
Time Frame: 6-month baseline and 6-month post-intervention
Change = (6-month post-intervention average per-clinician weekly proportion - 6-month baseline average per-clinician weekly proportion). Proportion = number of chronic patients who received Rx => 50 MME per-clinician, per-week/total patients who received opioid Rx per-clinician, per-week
6-month baseline and 6-month post-intervention
Change in Average Per-clinician Log Total Weekly MME Between Baseline and Post-intervention for Chronic Opioid Patients (=> 50 MME Daily Dose Rxs)
Time Frame: 6-month baseline and 6-month post-intervention
Change = (6-month post-intervention average of natural log MME summed per-clinician, per-week - the 6-month baseline average of natural log MME summed per-clinician, per-week). Log(total MME) = log(Rx strength x number of pills x opioid conversion factor)
6-month baseline and 6-month post-intervention
