BACKGROUND/RATIONALE:
Despite consensus that effective hypertension treatment reduces morbidity and mortality, many patients in the United States continue to have suboptimal blood pressure (BP) control. Even with the provider resources and motivated patients inherent in a randomized clinical trial, over a third of patients participating in the ALLHAT study were not at their goal blood pressure of 140/90 after five years. Similarly, within VISN 12 we have found that as many as 30% of patients with hypertension are above the target BP of 140/90, despite routine physician reminders to patients who are above these goals. Moreover, preliminary results of an internally funded randomized trial suggest minimal impact of further physician-focused interventions to reduce patients' blood pressure.
OBJECTIVE(S):
We will have two primary objectives. First, because the intervention proposed is novel, we believe we need to demonstrate its efficacy in a methodologically rigorous fashion. Specifically we plan to demonstrate that veterans participating in a peer support intervention will have improved blood pressure control, knowledge of blood pressure treatment, both generally and for themselves, and a more active stance as patients.
Second, we will carefully examine the process by which our intervention achieves these goals, including examining such key structural variables as the frequency of peer support meetings, attendance of participants at these meetings, and use of healthcare professional support by the group leaders. As part of this second objective, we also seek to understand the fidelity with which the peer leaders are to deliver the intervention, and the satisfaction of both support group participants and leaders with the intervention.
METHODS:
There are three primary activities in the present project.
First, academicians from the Zablocki VA are working with the VFW and other community groups to develop a community-academic partnership that follows the principles of community-based participatory research. This key activity is underway and will continue beyond the present period of funding.
The second activity is the centerpiece of the present grant. We will conduct a cluster randomized clinical trial (RCT) of the use of peer-led support groups to improve BP control in patients with hypertension. Fifty posts drawn from the Veterans of Foreign Wars, American Legion, Vietnam Veterans Association, and National Association of Black Veterans will be randomly assigned to receive professionally delivered education regarding hypertension or to a peer support intervention.
The third activity is an evaluation of the processes involved in delivering the peer support intervention that will allow for successful replication, or to provide insight into why the expected improvement in BP control did not occur.
FINDINGS/RESULTS:
The veterans organizations with whom we have partnered are very supportive of hte project. So far, only two of the posts that we have contacted have declined participation. We have 50 visits scheduled and continue to schedule new ones.
IMPACT:
It is anticipated that this intervention will help participating veterans achieve optimal hypertension control. Doing so will reduce their risks for heart disease and stroke, and improve their quality of life. It is hoped that the collaborative nature of this intervention will strengthen the VA's ties to the veteran community, and establish important "partnerships for health." If successful, this intervention could serve as a model for managing chronic disease both within and outside the VA system.
