Background

Durham County, North Carolina, is a mix of rural and urban geography that is an ideal community in which to test implementation strategies to reduce hypertension disparities and improve population health. The overall prevalence of hypertension in Durham County is 42%, with substantial geographic heterogeneity in prevalence among whites and blacks. There is a strong association with residential racial isolation, suggesting opportunities to intervene at the neighborhood level to reduce hypertension disparities and improve population health.
Intervention
Two hundred fifty-eight Black men with severe hypertension seen at Lincoln Community Health Center were identified. A team of undergraduate and graduate students made outreach calls to these patients offering hypertension education and counseling along with a free blood pressure cuff. Of the identified patients, about half were able to be reached via phone, and most agreed to participate in the program. 82 blood pressure cuffs were distributed to patients free of charge. For those men who received a blood pressure cuff, about half began using it consistently and reported at least one self-measured blood pressure to their student caller. Students made follow up calls offering education on the health effects of hypertension and evidence-based strategies to lower blood pressure. Students also made referrals to resources at Lincoln Community Health Center that could help their patients manage their chronic conditions and address social determinants of health. There were four educational calls as a part of the program. Patients who successfully completed all 4 calls and received a blood pressure cuff were designated as “Hypertension Heroes”, stewards of health management and wellness in their communities. Twenty eight men achieved this status and received commemorative certificates in the mail.
Outcomes and Future Directions
Men who engaged in the program began self-monitoring their blood pressure more frequently. Upon follow-up calls in the spring, many individuals were still using their blood pressure cuffs consistently. The student calls were well-received among patients who appreciated the individualized coaching and partnership, as well as students who gained insight into the patient experience and developed a deeper understanding of the barriers to chronic disease management.
"The excitement of making a direct impact on members of my community is something that has always driven me towards the field of medicine, and through this project I was able to do just that.” –Ashwin Gadiraju, undergraduate team member
Future efforts will focus on transitioning a virtual program back to in-person classes as the COVID-19 pandemic subsides. A virtual zoom-based course for patients with hypertension is currently under development. Funding has also been secured to expand the intervention to Spanish-speaking patients and women.
