Abstract

In this evidence-based educational project, I identified the gap in practice with the lack of nurses' knowledge in culturally tailored hypertension management among nurses caring for African American adults at a family nurse practitioner clinic. In this Doctor of Nursing Practice (DNP) project, I focused on a staff education initiative to improve nurses' knowledge to reduce disproportionately high rates of hypertension, complications, and mortality due to factors such as limited access to care, medication nonadherence, mistrust of providers, and improve on culturally competent interventions. The guiding practice-focused question was: Does educating nurses on hypertension in the African American population improve knowledge, as evidenced by pre- and post-surveys? I used the ADDIE (analysis, design, development, implementation, and evaluation) and Johns Hopkins evidence-based practice (JHEBP) models for this project. I searched the Walden University Library and found 42 studies of which I selected 10 using the Johns Hopkins Individual Evidence Summary Tool. Ten registered nurses voluntarily participated in two on-site PowerPoint presentation sessions. The results of the pre- and post-surveys indicate a percentage point improvement in the mean score. The results showed a statistically significant improvement, with mean scores increasing from 32.0% to 80.8%, reflecting a mean gain of 48.8 percentage points, t(9) = 48.91, p < .001. The most notable improvements were in community-based strategies (59%), medication adherence barriers (50%), and cultural determinants of health (48%). The nursing significance lies in equipping nurses with evidence-based, culturally competent skills to address health disparities, build trust, and promote adherence, ultimately improving outcomes for underserved populations.
