A Nurse-Led Intervention to Extend the HIV Treatment Cascade for cardiovascular disease prevention (EXTRA-CVD)
Years: 2018-2023
Background
People living with HIV (PLWHIV or PLWH) are at high risk for developing cardiovascular disease (CVD). Although HIV-specific factors play a role in CVD, traditional risk factors–including hypertension and hyperlipidemia–account for the vast majority of risk. The EXTRA-CVD Study tests a nurse-led intervention to improve control of hypertension and hyperlipidemia in PLWHIV.
The intervention consists of four evidenced-based components:
- nurse-led care coordination,
- nurse-managed medication protocols and adherence support,
- home blood pressure monitoring, and
- electronic medical records support tools.
This study aims to:
- Conduct a baseline assessment of atherosclerotic cardiovascular disease (ASCVD) preventative care and perceptions of ASCVD risk in the HIV specialty clinic environment;
- Evaluate the 12-month efficacy of the EXTRA-CVD intervention to improve BP and cholesterol control in PLWHIV; and
- Conduct a process evaluation of the EXTRA-CVD intervention.
Research Design
EXTRA-CVD is a mixed-methods clinical effectiveness trial design using an intent to treat approach. For the trial component of the study, 300 participants were randomized 1:1 to the nurse-led intervention versus an educational control. The primary outcome will be the change in systolic blood pressure and the secondary outcome will be change in non-HDL cholesterol. Participants will complete measures at baseline, 4, 8, and 12 months. A mixed-methods process evaluation will be used to monitor program implementation and better understand the relationship between the intervention components and health outcomes. This study was registered at ClinicalTrials.gov #NCT03643705
Results
All EXTRA-CVD data are collected and data analysis for Aims 2 and 3 are currently underway.
