NCT06640023

Brief Summary

The goal of this clinical trial is to learn if electronic health record (EHR) nudges (changes to the EHR that do not restrict freedom of choice or alter incentives) can reduce Z-drug prescribing in primary care clinics for patients with insomnia. The main questions it aims to answer are:

  1. 1.Can Z-drug prescribing be reduced by setting the dispense quantity default of new Z-drug orders in the EHR to 10 pills with 0 refills?
  2. 2.Can Z-drug prescribing be reduced by an EHR alert that suggests clinicians remove a Z-drug and/or add an evidence-based behavioral treatment for insomnia, followed by a request to justify their reasoning if the suggestion is not followed?
  3. 3.Does combining these two nudges reduce Z-drug prescribing?
  4. 4.Complete an introductory educational module about treating insomnia and relevant EHR changes.
  5. 5.Complete their routine patient visits.
  6. 6.Either experience EHR changes when prescribing Z-drugs, including a Z-drug dispense quantity default of 10 pills for new orders, a prompt to remove or justify Z-drug orders, both, or neither.

Study Arms (4)

Control

NO INTERVENTION

Clinicians randomized to this arm receive guideline education prior to the trial.

Z-drug Default Quantity

EXPERIMENTAL

Clinicians randomized to this arm receive guideline education + 10 pill quantity defaults.

Behavioral: Z-drug Default Quantity

Redirection + Accountable Justification

EXPERIMENTAL

Clinicians randomized to this arm receive guideline education + alerts requiring justification of orders discordant with guidelines. Justifications are entered in the patient's medical record, and can be viewed by other clinicians.

Interventions

For new orders of oral Z-drugs tablets (zolpidem, zolpidem CR, zaleplon, and eszopiclone), the EHR dispense quantity default will be changed to 10 pills with 0 refills for all dosage levels. Dispense quantities for Z-drug reorders and renewals will not be changed.

CombinedZ-drug Default Quantity

For qualifying Z-drug orders, an EHR alert will suggest removing the Z-drug, adding a CBT-I referral, or both. If the alert recommendation is not followed, clinicians will be asked to provide a justification for their decision when the order is signed. The justification will display in the Encounter Report. The alert suggestion depends on the recent history of Z-drug prescriptions for a given patient. When a Z-drug is being ordered for patients with 180 days supply of Z-drugs or fewer in the last 365 days, the alert will prompt removal of the Z-drug and addition of a CBT-I referral to the order. When a Z-drug is being ordered for patients with 181 days supply of Z-drugs or more in the last 365 days, the alert will only prompt addition of a CBT-I referral to the order. If a CBT-I referral is already in the current order or has been ordered for a patient in the past 180 days, the alert to add a CBT-I referral to the order will not display.
