Study Overview
Brief Summary
The purpose of this cluster randomized control trial is to test whether a multimodality strategy that includes an educational on-line course and performance feedback reports is effective to reduce clinical inertia in the management of hypertension in rural primary care clinics in the Dominican Republic.
Detailed Description
Proper control of elevated blood pressure (BP) is complex due to the large number of factors associated with therapy such as patient lifestyle, therapeutic adherence and access to health care, especially in low and middle income countries. More recently another obstacle has been described; clinical inertia, defined as the failure of clinicians to initiate or intensify antihypertensive therapy despite elevated BP levels not at goal. Suboptimal therapy is the most clinically important modifiable factor known to be associated with poor BP control. Reducing clinical inertia is of significant relevance, since a proper control of hypertension can reduce mortality from coronary heart disease and mortality from cerebrovascular disease.
Our hypothesis is that a multimodality strategy that includes an on-line course on updated guidelines on hypertension management and feedback performance reports is effective to reduce clinical inertia in the management of hypertension in rural primary care clinics in the Dominican Republic.
To test this hypothesis, this study will enroll eight clinics in rural neighborhoods of the Peravia province. These are government-funded small clinics that provide primary care and preventive services and are staffed with 2-3 primary care physicians. Eight clinics will be randomized at a 1:1 ratio into a control group and and intervention group. We anticipate over 500 patients from these clinics will be included.
The primary care physicians in the intervention group will be provided with an on-line course and weekly performance feedback reports, based on the new American College of Cardiology/American Heart Association (ACC/AHA) and European Society of Cardiology/European Society of Hypertension (ESC/ESH) hypertension guidelines. The performance feedback reports will include percent of patients with uncontrolled hypertension and among this group percent of visits where intensification in anti-hypertensive therapy was made. It will also include a comparative assessment of the performance of the physicians compared to their colleagues. The control group will continue to follow the current usual care without intervention. The total intervention and follow-up time will be 16 weeks.

Arms & Interventions
Control group
The clinicians in the control group will continue usual care without intervention. They will not receive the online course or performance feedback reports.
Intervention group
The primary care physicians will receive access to an online course on hypertension management based on the ACC/AHA and ESC guidelines. They will also receive feedback reports on their performance on hypertension management for 16 weeks.
Intervention: Multimodality behavioral strategy (Other)
Outcomes
Primary Outcomes
Proportion of visits with clinical inertia
Time Frame: 16 weeks
Clinical inertia will be designated to visits where BP was uncontrolled (BP ≥140/90 or ≥130/80 in patients with comorbidities) where no intensification of therapy was done or no justification for deferring intensification was documented.
Secondary Outcomes
- Percentage of clinic visits where counseling on lifestyle modifications was provided(16 weeks)
- Percentage of patients on guideline concordant hypertension management(16 weeks)
- Percentage of clinic visits with controlled blood pressure(16 weeks)
