Cardiovascular disease (CVD) is the leading cause of death in the United States; more than
80% of veterans have > 2 risk factors for CVD. Our study is one of the first to examine the
implementation of a tailored behavioral/educational self-management intervention in primary
care clinics designed to improve CVD risk. The proposed study could result in a leap
forward in CVD risk management among veterans for several reasons: 1) ) This is a novel
extension of our previous interventions that have demonstrated improved BP, now designed to
address multiple chronic conditions contributing to CVD risk, particularly hyperlipidemia
and diabetes. The study focuses on both multiple CVD-related risk factor management and
medication management 2) The intervention is multi-behavioral; it addresses patients'
various health behavior (e.g., smoking, diet, and medication adherence). 3) Components of
the intervention will include specific recommendations and transportability of intervention
application software and tracking packages that will allow clinic managers to implement the
intervention if it is effective.

Anticipated Impacts on Veteran's Healthcare: Cardiovascular disease (CVD) is the leading
cause of death in the U.S.; more than 80% of veterans have > 2 risk factors for CVD. An
intervention that addresses multiple CVD risk factors among high-risk veterans has the
greatest potential to improve morbidity and mortality.

Project Background/Rationale: The proposed study will take place in two VA primary care
clinics (1-Community-Based Outpatient Clinics and 1-primary care clinic affiliated with a
hospital). We will improve CVD risk among veterans by addressing the modifiable risk factors
of systolic blood pressure (SBP), smoking, and low-density lipoprotein cholesterol (LDL-C).
The intervention will be tailored to the needs of vulnerable high risk patients (e.g.
African Americans, low literate) and integrated into clinics, thereby enhancing the
potential for benefit and generalizability to other settings.

The proposed study could significantly improve CVD risk management among veterans for
several reasons: 1) This intervention is a novel extension of our previous efficacious
interventions, but provides a novel extension to address multiple chronic conditions
contributing to CVD risk. 2) The intervention focuses on both multiple CVD-related behaviors
and medication management. 3) The intervention was developed to ensure implementation across
a large and representative sample of veterans; and; 4) The intervention, if found
efficacious and financially self-sustaining, could be widely implemented within the VA
healthcare system.

Project Objectives: The proposed study will examine two research questions:

1. Can patients randomized to a clinical pharmacist-administered telephone behavioral/
medication management intervention tailored to their needs improve CVD outcomes
relative to a control group over 12 months? Primary Hypothesis: (H1) Veterans who
receive the behavioral/medication intervention will have greater improvement of their
CVD Risk Profile over the 12 months of follow-up as compared to the control group.

Secondary Hypotheses: (H2) Veterans who receive the intervention will have improved
medication adherence, physical activity, improved diet, lower body mass index as
compared to the control group over 12 months of follow-up. (H3) Veterans who receive
the intervention will have greater improvements in LDL over the 12 months of follow-up
as compared to the control group. (H4) Veterans with diabetes who receive the
intervention will have greater improved HbA1c as compared to the control group over 12
months of follow-up.

2. If the intervention is found to be effective, is it cost effective? Project Methods: To
address these hypotheses, we propose a two-arm randomized clinical trial design in
which 500 patients with cardiovascular disease will be randomized to either the
education control group or the intervention group. Patients randomized to the
intervention group will receive a clinical pharmacist-administered intervention, which
focuses on behavioral and a medication management. The intervention will occur over 12
months. Patients randomized to the control group will receive educational material
about CVD reduction. Given the national prevalence of CVD and the dismal rates of risk
factor control, intensive, but easily disseminated interventions such as the one
proposed could significantly improve treatment of this epidemic in the VA.
