NCT00815789

Brief Summary

The goal of this study is to improve cardiovascular disease (CVD) and cholesterol in African Americans adults with diabetes by addressing the modifiable risk factors of systolic blood pressure (SBP), glycosylated hemoglobin (Hb A1c), and low-density lipoprotein cholesterol (LDL-C). We will evaluate the impact of a tailored CVD risk management intervention administered by nurses via the telephone. The intervention incorporates medication management and behavioral modification and will be tailored to the needs of vulnerable high risk subjects (e.g. African Americans, low socioeconomic status, low literate). It will be integrated into community clinics, thereby enhancing the potential for benefit and generalizability to other settings. The primary hypothesis is that among African American subjects with diabetes, a nurse administered, tailored cardiovascular risk management intervention targeting both medication management and behavioral patient self-management will decrease SBP by 5 mmHg, Hb A1c by 0.5%, and LDL-C by 20 mg/dl over 12 months relative to the cardiovascular education-only control group.

Outcome Measures

Primary Outcomes (1)

  • Change in the outcome (SBP, Hb A1c, or LDL) from baseline to the 12 month evaluation.

    12 months

Secondary Outcomes (1)

  • Changes in CVD related health behaviors (e.g., aspirin use, medication adherence, exercise, and diet) as well as changes in stroke and CHD risk as assessed by the UPKDS risk engine

    12 months

Study Arms (2)

Intervention

EXPERIMENTAL

A nurse-administered intervention, which includes a behavioral and a medication management component. The intervention consists of very brief monthly telephone calls and occurs over 12 months. Upon request, participants may also be mailed additional supportive educational material to supplement phone intervention. They will also receive a letter clarifying medications reviewed with them during the nurse-administered intervention.

Behavioral: Tailored cardiovascular risk management (Nurse-administered )

Control

NO INTERVENTION

Receive educational material about CVD reduction at baseline
