Statin Reminders for Improving Prescribing in Primary Care

December 8, 2025 updated by: Aileen P. Wright, Vanderbilt University Medical Center

Interruptive Versus Non-Interruptive Reminders for Statin tHerApy in Primary Care (INIRSHA-PC). A Randomized Trial.

Statins reduce cardiovascular events and mortality, but only 30% of eligible primary care patients nationally are on statins. Clinical decision support (CDS) interventions in the electronic health record (EHR) can deliver education to providers and increase adherence to guideline recommendations via many potential forms of delivery. Interruptive alerts are an effective form of CDS but disrupt clinician workflow and increase alert fatigue in an age of clinician burnout and frustration with the EHR. Non-interruptive reminders are proposed as an alternative method of delivering CDS; however, they require active pursuit by the provider, and their effectiveness compared to interruptive alerts has not been rigorously studied. The investigators propose a randomized trial comparing the effect of interruptive vs. non-interruptive reminders displayed to clinicians to increase statin prescribing in primary care clinics.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
3332

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Interruptive Reminder Group
Providers will receive education via a pop-up alert at the time that the chart is opened for eligible patient visits assigned to the interruptive reminder group.
Other: Interruptive Reminder
The reminder will display at the time the chart is opened for eligible patient visits and alert clinicians that a statin is recommended for the patient and list the reasons the statin is indicated. It will give the clinicians a defaulted option for statin prescription as well as alternatives. If the clinician accepts the alert, an order for a statin will be placed in their "shopping cart" for convenience, and the order can be signed to prescribe the medication. If the clinician does not wish to prescribe a statin from the reminder, they can choose an acknowledgement reason.
Active Comparator: Non-Interruptive Reminder Group
Providers will be able to seek out education at their own initiative via an on-demand reminder within a section of the chart for eligible patient visits assigned to the non-interruptive reminder group.
Other: Non-interruptive Reminder
The reminder will have the same format as the interruptive reminder group, but it will not be displayed unless providers seek out the education at their own initiative. The reminder will alert clinicians that a statin is recommended for the patient and list the reasons the statin is indicated. It will give the clinicians a defaulted option for statin prescription as well as alternatives. If the clinician accepts the alert, an order for a statin will be placed in their "shopping cart" for convenience, and the order can be signed to prescribe the medication. If the clinician does not wish to prescribe a statin from the reminder, they can choose an acknowledgement reason.
Active Comparator: No Reminder Group
No alert recommending a statin will be displayed/available to the provider. The system will record eligibility through triggering a "silent" reminder, which is not displayed to the clinician and exists solely for data collection purposes.
Other: No Reminder
No reminder recommending a statin will be displayed/available to the provider.

What is the study measuring?
