Brief Summary

Rheumatoid arthritis (RA) is a autoimmune disease associated with an increased risk of developing coronary artery disease (CAD) and premature death, particularly in Black patients. Traditional CAD risk factors like hypertension (HTN) are both very common and poorly controlled among Black RA patients. Disparities in RA disease activity further increase the risk of CAD in this population. Black patients face significant barriers when seeking RA care, and the investigators suspect similar challenges affect HTN care in this population. The goals of this project are to identify and address barriers to HTN care in patients with RA to reduce disparities in HTN and CAD outcomes for Black RA patients.

Interviews with Black RA patients, rheumatology providers, and primary care providers in the Duke University Health System will be conducted to describe barriers to HTN care in Black RA patients. Interviews will focus on access to care, patient-provider communication, coordination of care, and the challenges of managing HTN in patients with RA. These interviews will help us to develop an intervention that will focus on improving uncontrolled HTN in Black RA patients. The investigators plan to do this by empowering Black RA patients to actively participate in their HTN care, improving patient-provider communication, and improving coordination between primary care and rheumatology providers. If successful, our intervention has the potential to reduce rates of CAD and associated death for Black RA patients.

Arm && Interventions
GroupInterventionDescription
Blood pressure intervention armBlood pressure intervention armThe investigators will recruit 25 Black RA patients with HTN for the study. Participants will be provided with a home blood pressure monitor, teaching from nursing staff regarding the correct use of the monitor, and a guide to help interpret normal and elevated blood pressure values. Participants will be instructed to obtain and record blood pressure values at least three times per week over the course of 3 months. Every 2 weeks, these results will be sent to the study team, and participants will complete a brief survey regarding other factors that may influence blood pressure control, including RA disease activity (RAPID3 score), pain, current use of acute RA therapies, anti-hypertensive medication use, anti-hypertensive medication adherence, and current perceived barriers to HTN self-management.
Primary Outcome Measures
NameTimeMethod

Percentage of expected surveys completed by participants

Intervention feasibility as measured by participant retention6 months

Percentage of participants who successfully complete the study

Intervention feasibility as measured by sustainability of data collection procedures6 months

Financial and time commitments required to successfully collect participant surveys, blood pressure monitoring results, send information to providers, and monitor provider responses

Intervention feasibility as measured by sample characteristics6 months

Description of sociodemographic characteristics of population, rheumatoid arthritis characteristics (eg, duration, medications, severity), and hypertension characteristics (eg, duration, medications, severity)

Perceived appropriateness of the intervention to address the health care disparity in HTN (hypertension) control for Black RA patients as measured by qualitative interviews6 months

Qualitative interviews will be performed at the end of the pilot intervention with all study participants to assess the perceived appropriateness of the intervention to address the health care disparity in HTN control for Black RA patients. Rheumatology and primary care providers caring for study participants will also be invited to comment on the appropriateness of the intervention.

Intervention feasibility as measured by adherence to blood pressure monitoring6 months

Percentage of expected blood pressures reported by participants

Intervention feasibility as measured by use of resources6 months

Cost of participant recruitment, education, blood pressure monitors, participant compensation, research coordinator time and cost needed to collect data, and statistical analysis

Intervention feasibility as measured by participant accrual rates6 months

Rate at which participants are able to be successfully recruited

Intervention acceptability as measured by qualitative interviews6 months

Qualitative interviews will be performed at the end of the pilot intervention with all study participants to assess the acceptability of the intervention. Rheumatology and primary care providers caring for study participants will also be invited to comment on the acceptability of the intervention.
