Personalizing Intervention to Reduce Clinical Inertia in the Treatment of Hypertension

August 19, 2024 updated by: Nancy Haff, MD, MPH, Brigham and Women's Hospital
This is a three-arm pragmatic randomized controlled trial to test two interventions targeting clinical inertia in hypertension compared to control, followed by predictive modeling to identify factors that are associated with intervention responsiveness. Study investigators will use EHR data to identify providers of patients whose hypertension treatment was not intensified. Primary care physicians will then be randomized to one of three arms: pharmacist e-detailing, provider dashboards, or no intervention (control). After the intervention, the investigators will conduct virtual interviews with select providers from each arm. A predictive modeling approach will then be used to identify patient and provider characteristics that are associated with inertia and with responsiveness to each intervention.

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

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.

Detailed Description

We propose a pragmatic randomized controlled trial to test two interventions targeting clinical inertia in hypertension compared to control, followed by predictive modeling to identify factors that are associated with intervention responsiveness.

For Aim 1, we will use Electronic Health Record (EHR) data to identify physicians of patients whose hypertension treatment was not intensified despite their having persistently elevated blood pressure. We will then randomize primary care physicians to on of three arms: academic e-detailing, social norming, or no intervention (control).

For Aim 2, we will conduct interviews with select physicians from each arm. We will then identify patient and physician characteristics that are associated with inertia and with responsiveness to each intervention.

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

18 years to 79 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Provider Inclusion Criteria:

  • Primary care physician
  • Practicing in primary care at Massachusetts General Hospital
  • Caring for at least 2 patients: (1) aged 18-79, (2) for whom the recent BP history in the last 18 months is above goal, (3) whose most recent BP at an outpatient visit was above goal, and (4) who did not have their hypertension treatment regimens intensified (dose increase, new medication, or medication exchange) at or since that time. The BP goal will be <140/90 for all patients. To accommodate changes in care delivery that occurred during the COVID surge, outpatient visits will include in-office and virtual visits that had vitals recorded in the EHR the same day.

Provider Exclusion Criteria:

  • fewer than 100 patients on their primary care panel
  • practice less than one session per week

Patient Inclusion Criteria:

  • had a blood pressure greater than 140/90 mmHg at 2+ PCP visits in the past 12 months
  • treatment was not intensified at any of these visits

Patient Exclusion Criteria:

  • excluded from the hypertension registry
  • currently pregnant or post-partum 6 months
  • receiving hospice care

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.
Experimental: Audit and Feedback
A report of the provider's hypertension control rates compared to benchmark will be displayed using principles of social norming. We will present that provider's hypertension control rates compared to the 90th percentile of their peers.
Behavioral: Audit and Feedback
A report of the provider's hypertension control rates compared to benchmark will be displayed using principles of social norming. We will present that provider's hypertension control rates compared to the 90th percentile of their peers.
Experimental: Pharmacist E-Detailing
A pharmacist will review the chart in advance and provide a personalized recommendation for how to intensify the specific patient's antihypertensive regimen based on current guidelines. For example, they might recommend adding an additional medication based on the patient's comorbid conditions and could suggest a starting dose and timeframe for dose escalation.
Behavioral: Pharmacist E-Detailing
A pharmacist will review the chart in advance and provide a personalized recommendation for how to intensify the specific patient's antihypertensive regimen based on current guidelines. For example, they might recommend adding an additional medication based on the patient's comorbid conditions and could suggest a starting dose and timeframe for dose escalation.
No Intervention: Control
No intervention will be provided to physicians in the control arm.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment Intensification
Time Frame: During the primary care office visit in which the provider-patient dyad received the intervention
The primary outcome was whether physicians intensified treatment at the target visit. Intensification was defined as adding a new antihypertensive medication or increasing the total daily dose of an existing one. This was measured by identifying all prescriptions for anti-hypertensive medications in the electronic health record (EHR) on the day of the target visit and comparing the medication name and total daily dose to anti-hypertensive medications prescribed prior to the target visit date, following the same procedure used to identify intensification during the eligibility assessment
During the primary care office visit in which the provider-patient dyad received the intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in systolic blood pressure
Time Frame: Up to 6 months following the intervention date
The initial value will be the systolic blood pressure at the time of the visit targeted by the intervention. The follow-up blood pressure will be the last blood pressure available in the EHR within 6 months after the visit targeted by the intervention.
Up to 6 months following the intervention date
