    Despite the availability of efficacious treatments, only half of patients with hypertension achieve adequate blood pressure (BP) control. This paper describes the protocol and baseline subject characteristics of a 2-arm, 18-month randomized clinical trial of titrated disease management (TDM) for patients with pharmaceutically-treated hypertension for whom systolic blood pressure (SBP) is not controlled (≥140mmHg for non-diabetic or ≥130mmHg for diabetic patients). The trial is being conducted among patients of four clinic locations associated with a Veterans Affairs Medical Center. An intervention arm has a TDM strategy in which patients' hypertension control at baseline, 6, and 12months determines the resource intensity of disease management. Intensity levels include: a low-intensity strategy utilizing a licensed practical nurse to provide bi-monthly, non-tailored behavioral support calls to patients whose SBP comes under control; medium-intensity strategy utilizing a registered nurse to provide monthly tailored behavioral support telephone calls plus home BP monitoring; and high-intensity strategy utilizing a pharmacist to provide monthly tailored behavioral support telephone calls, home BP monitoring, and pharmacist-directed medication management. Control arm patients receive the low-intensity strategy regardless of BP control. The primary outcome is SBP. There are 385 randomized (192 intervention; 193 control) veterans that are predominately older (mean age 63.5years) men (92.5%). 61.8% are African American, and the mean baseline SBP for all subjects is 143.6mmHg. This trial will determine if a disease management program that is titrated by matching the intensity of resources to patients' BP control leads to superior outcomes compared to a low-intensity management strategy.

    The Cholesterol, Hypertension, And Glucose Education (CHANGE) study: results from a randomized controlled trial in African Americans with diabetes.

    Background

    Cardiovascular disease (CVD) and diabetes account for one-third of the mortality difference between African American and white patients. We evaluated the effect of a CVD risk reduction intervention in African Americans with diabetes.

    Methods

    We randomized 359 African Americans with type 2 diabetes to receive usual care or a nurse telephone intervention. The 12-month intervention provided monthly self-management support and quarterly medication management facilitation. Coprimary outcomes were changes in systolic blood pressure (SBP), hemoglobin A1c (HbA1c), and low-density lipoprotein cholesterol (LDL-C) over 12 months. We estimated between-intervention group differences over time using linear mixed-effects models. The secondary outcome was self-reported medication adherence.

    Results

    The sample was 72% female; 49% had low health literacy, and 37% had annual income <$10,000. Model-based estimates for mean baseline SBP, HbA1c, and LDL-C were 136.8 mm Hg (95% CI 135.0-138.6), 8.0% (95% CI 7.8-8.2), and 99.1 mg/dL (95% CI 94.7-103.5), respectively. Intervention patients received 9.9 (SD 3.0) intervention calls on average. Primary providers replied to 76% of nurse medication management facilitation contacts, 18% of these resulted in medication changes. There were no between-group differences over time for SBP (P = .11), HbA1c (P = .66), or LDL-C (P = .79). Intervention patients were more likely than those receiving usual care to report improved medication adherence (odds ratio 4.4, 95% CI 1.8-10.6, P = .0008), but adherent patients did not exhibit relative improvement in primary outcomes.

    Conclusions

    This intervention improved self-reported medication adherence but not CVD risk factor control among African Americans with diabetes. Further research is needed to determine how to maximally impact CVD risk factors in African American patients.
