Brief Summary:
Strategies to improve uptake of cardiovascular disease preventive therapies among people living with HIV (PLHIV) are urgently needed. This study tests an innovative prevention nurse intervention to extend the HIV/AIDS treatment cascade for the treatment of hypertension and hyperlipidemia among PLHIV on suppressive antiretroviral therapy. This intervention may be scalable as an extension of ongoing HIV/AIDS treatment cascade initiatives in HIV specialty clinics nationwide.

People living with HIV (PLHIV) are at increased risk for atherosclerotic cardiovascular disease (ASCVD); however, uptake of evidence based therapies to prevent ASCVD is sub-optimal. Reasons for under treatment may include low perceived risk, competing priorities for HIV specialist providers, and poor trust and communication with non-HIV primary care providers. This project proposes a nurse-led intervention to extend the HIV/AIDS treatment cascade-a widely adopted framework developed to improve access to high quality HIV care-for CVD prevention, specifically to improve control of blood pressure and hyperlipidemia in PLHIV on antiretroviral therapy who have suppressed HIV viral load. The study will be conducted in three racially and ethnically diverse clinic contexts [University Hospitals (Cleveland, OH), MetroHealth (Cleveland, OH) and Duke Health (Durham, NC)] that are broadly representative of HIV specialty care in the US. Using a mixed-methods clinical effectiveness trial design, this project will test the 12-month efficacy of a multi-component intervention among n=300 HIV+ adults on suppressive ART with hypertension and hyperlipidemia. Participants will be randomized 1:1 to intervention vs. education control. Control participants will receive general prevention education. The intervention will consist of four evidence-based components derived from prior studies in the general population: (1) nurse-led care coordination, (2) nurse-managed medication protocols and adherence support (3) home BP monitoring, and (4) electronic medical records (EMR) support tools. These components will be further adapted to the HIV specialty clinic context with key stakeholder input and using data from a mixed-methods study of current ASCVD preventive care practices at the three HIV clinic sites. A process evaluation of the prevention nurse intervention will be conducted, which will assess fidelity, dose, recruitment, reach, and context. Two key contextual process measures of interest will be changes in perceived ASCVD risk and changes in trust and communication between PLHIV participants and their HIV and non-HIV providers. If proven effective to reduce both blood pressure and cholesterol as postulated, this nurse-led intervention will have substantial clinical impact among high-risk PLHIV, potentially reducing ASCVD events by more than a quarter. This model is potentially scalable as an extension of HIV treatment cascade initiatives nationwide.

Experimental: Nurse Intervention
This multi-component intervention will consist of four evidence-based components delivered at 4 in-person visits (0, 4, 8, and 12 months) and by telephone contact: (1) nurse-led care coordination, (2) nurse-managed medication protocols and adherence support (3) home blood pressure monitoring, and (4) electronic medical records support tools.

Other: Multi-component intervention
4 components as described |

Active Comparator: Education Control
Participants in the education control arm will receive general prevention education delivered at 4 in-person visits (0, 4, 8, and 12 months), which will consist of evidence-based material on diet, exercise, smoking, sexually transmitted infections, and cancer prevention.

Primary Outcome Measures :
- Systolic blood pressure [ Time Frame: 12 months ]Repeated measures across 4 time points (0, 4, 8, and 12 months)
Secondary Outcome Measures :
- Non high density lipoprotein (Non-HDL) cholesterol [ Time Frame: 12 months ]Repeated measures across 4 time points (0, 4, 8, and 12 months)
Other Outcome Measures:
- % of subjects in each hypertension cascade category [ Time Frame: 12 months ]Ordinal 4-level variable across 4 time points (0, 4, 8, and 12 months). The hypertension cascade tool consists of mutually exclusive categories as follows: 1=undiagnosed hypertension; 2=hypertension diagnosed; 3=hypertension diagnosed and appropriately managed; 4=hypertension diagnosed, appropriately managed, and blood pressure target achieved.
- % of subjects in each hyperlipidemia cascade category [ Time Frame: 12 months ]Ordinal 4-level variable across 4 time points (0, 4, 8, and 12 months). The hypercholesterolemia cascade tool consists of ordered categories as follows: 1=undiagnosed hyperlipidemia; 2=hyperlipidemia diagnosed; 3=hyperlipidemia diagnosed and appropriately managed; 4=hyperlipidemia diagnosed, appropriately managed, and non-HDL cholesterol target achieved.

| Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Criteria
Inclusion Criteria:
- Age ≥18 years
- Laboratory confirmed HIV+ diagnosis
- Undetectable HIV viral load: defined as the most recent HIV viral load <200 copies/mL, checked within the past year (assessed via chart abstraction)
- Hypertension: defined as systolic blood pressure >140 mmHg on ≥ 2 occasions in the past 12 months or on an antihypertensive medication (assessed via chart abstraction)
- Hyperlipidemia: defined as a non-high-density lipoprotein cholesterol level that is greater than the National Lipid Association target [130mg/dl for moderate to high risk (≥ 2 major risk factors) or 100mg/dl for very high risk (known ASCVD or diabetes + ≥2 major risk factors)]. Major risk factors include HIV, Age >45 men or >55 women, family history of early coronary artery disease, smoking, hypertension, low high-density lipoprotein cholesterol. By design, all participants in our study will be ≥ moderate risk.
Exclusion Criteria:
- On lipid-lowering medication solely for cardiovascular disease prevention with evidence of pre-medication non-high-density lipoprotein cholesterol which was already below National Lipid Association target
- On anti-hypertensive medications solely for a non-hypertension indication (e.g. systolic heart failure)
- Severely hearing or speech impaired, or other disability that would limit participation in the intervention components
- In a nursing home and/or receiving in-patient psychiatric care
- Terminal illness with life expectancy < 4 months
- No reliable access to a telephone
- Pregnant, breast-feeding, or planning a pregnancy during the study period
- Planning to move out of the area in the next 12 months
