  Purpose

PLEASE NOTE: THIS STUDY IS ONLY ENROLLING PATIENTS CURRENTLY BEING TREATED AT BELAIR-EDISON FAMILY HEALTH CENTER.

The purpose of this study is to compare the clinical effectiveness and cost effectiveness of two cardiovascular risk reduction programs - a comprehensive intensive (Cl) intervention with a less intensive (LI) intervention - in African American, and white low-income patients with known excessive cardiovascular disease risk.

Primary Outcome Measures:
  • Low-density Lipoprotein Cholesterol [ Time Frame: Measured at 1 year ]
    Blood was drawn after a 12 hour fast and low density lipoprotein cholesterol was measured in a standardized lab

  • Systolic Blood Pressure [ Time Frame: Measured at 1 year ]
    Blood pressure measured with automatic blood pressure machine according to the guidelines of the American Heart Association.

  • HbA1c [ Time Frame: Measured at 1 year ]
    Fasting for 12 hour blood sample was measured in standardized lab


Secondary Outcome Measures:
  • Patients' Satisfaction With Care and Health Care Utilization [ Time Frame: Measured at 1 year ]
    Patient satisfaction with care and healthcare utilization was measured with the Patient Assessment for Chronic Illness Care Scale (PACIC). The scores range from 0-5, with 5 being the most satisfied

Arms Assigned Interventions
Active Comparator: Comprehensive Intervention Group
The NP/CHW intervention focused on behavioral interventions to affect therapeutic lifestyle changes and adherence to medications and appointments as well as the prescription and titration of medications for one year. The NP and CHW worked as a team. The NP oversaw the initial assessment and, in collaboration with the CHW, tailored the intervention plan, conducted the intervention including lifestyle modification counseling and medication titration and prescription, consulted with the physician, and supervised the CHW. Specific algorithms for drug treatment of hyperlipidemia, hypertension (HBP), hyperglycemia, ACE, and β-blocker therapy were developed for this study based on current guidelines and standards of care.
Behavioral: Lifestyle Changes
Nutrition counseling, smoking cessation counseling, medication compliance counseling, exercise
Drug: Antiplatelet Agents
Aspirin 81 mg q day

Drug: Beta Blocker
Oral medication
Other Names:
  • Metoprolol
  • Toprol
  • Atenolol
  • Propranolol
Drug: ACE Inhibitors
Oral medications, received 1-2 times per day
Other Name: Lisinopril
Active Comparator: Less Intensive Intervention Group
Participants will receive usual care from their physicians and a Less Intensive (LI) intervention of feedback on cardiovascular disease (CVD) risk factors and guidelines to patients and their physicians. Patients and their providers in the received the results of baseline lipids, BP, and HbA1c along with the recommended goal levels and a pamphlet on controlling risk factors published by the American Heart Association. In addition, providers received copies of the AHA/ACC Guidelines for Secondary Prevention.
Behavioral: Lifestyle Changes

Detailed Description:

BACKGROUND:

The study is based on the premise that a community-based participatory research partnership model, using a team of an advanced practice nurse case manager, community health worker (CHW), and physician can be translated into urban community clinics and improve the quality of care and reduce disparities in cardiovascular health in minority and other underserved populations. Despite well-publicized guidelines on the appropriate management of cardiovascular disease (CVD) and type 2 diabetes, implementation of CVD risk-reducing practices remains poor. In spite of the known benefit of lowering low-density lipoprotein cholesterol (LDL-C) levels below 100 mg/dl in persons with existing heart disease, as many as 50 to 70 percent of eligible CVD patients are not placed on lipid-lowering therapy by their providers and from 20 to 80 percent of patients do not achieve the goals of therapy. The benefits of controlling high blood pressure (HBP) are well established, yet national rates of HBP control remain at only 31 percent despite decades of provider and patient education. In addition, it is well established that control of glycemia, hyperlipidemia, and blood pressure reduce the risk of vascular complications in people with diabetes, 75 percent of whom die from some form of heart or blood vessel disease. This randomized trial will compare the clinical effectiveness and cost effectiveness of a CI intervention with a LI intervention in African American, and white low-income patients with known excessive CVD risk.

DESIGN NARRATIVE:

Eligible patients with CVD or type 2 diabetes will be randomly selected from two urban federally funded community clinics and randomly assigned to receive either 1) a Cl intervention delivered by a nurse practitioner, a CHW, and the patient's physician, focusing on behavioral interventions to affect therapeutic lifestyle changes and medication adherence as well as the prescription and titration of medications or 2) a LI intervention providing feedback on CVD risk factors and guidelines to patients and their physicians. Outcomes will be measured at baseline and one and two years. It is hypothesized that a higher proportion of patients in the Cl intervention group will achieve the treatment goals for lipid, blood pressure, and diabetes management, lifestyle behaviors and utilization of antiplatelet agent, beta blocker, and angiotensin converting enzyme (ACE) inhibitor therapies and that the Cl intervention will be cost-effective. Secondary outcomes include assessment of the impact of the Cl intervention model on patients' satisfaction with care and health care utilization. The increase in the percentage of high-risk women and men who receive recommended secondary prevention therapies and achieve goal levels could potentially result in a marked decrement in annual CVD mortality and health disparities if applied within primary care settings to populations with the characteristics of the target groups for this study.
