Improving hypertension knowledge, medication adherence, and blood pressure control: A feasibility study

Abstract

Aims and objectives: To examine the feasibility of a culturally tailored education programme for Haitian immigrants diagnosed with hypertension.

Background: Hypertension is a major public health problem, impacting more than 26% of the global population. The overall prevalence of hypertension is 45.4% in the United States with nearly 80,000 deaths due to hypertension in 2015. African Americans and other Black populations living in the U.S. are disproportionally affected by hypertension.

Design: Pre-test and post-test feasibility study.

Methods: A convenience sample of forty-four participants who identified as Haitian immigrants was enrolled in this evidence-based education programme. The intervention included culturally tailored education focused on improving knowledge, medication adherence and blood pressure. Outcomes were measured using the Hill-Bone Medication Adherence Scale and Hypertension Knowledge Test. The SQUIRE 2.0 guidelines were used for reporting outcomes.

Results: Of the participants that completed the study (N=42), the mean age was 61.95 (± 9.75) years and 59% were female. Baseline systolic and diastolic blood pressures were 143 (±18.15) and 85 (±7.23), respectively. Six weeks after the intervention, there was a significant decrease in mean systolic, 126 (±12.07) and diastolic 78.50 (± 7.23) blood pressures. An increase in medication adherence and hypertension knowledge was also noted at the six-week follow-up period.

Conclusion: The feasibility of healthcare provider implementation of a culturally tailored intervention to manage hypertension has been demonstrated. However, future research is warranted to gain a more in-depth understanding of how to approach hypertension management among Haitians and other Black immigrant communities.

Relevance to clinical practice: Advanced practice nurses are uniquely qualified to implement evidence-based programmes that improve patient knowledge and adherence to hypertension management. Through tailoring and adopting an evidence-based methods for educating patients about medication adherence and adequate blood pressure management, there is a potential to see improvements in patient outcomes.
