<p> Hypertension is a common public health problem. Lack of self-care practices and non-adherence to treatment plans are among the primary reasons for the increasing cases of the condition. The project assessed the teach-back method and the reliability of assessment tools in improving health literacy and hypertension management among adult patients with hypertension. Effective patient education is critical for the control and treatment of hypertension. A convenience sampling was used to recruit patients with hypertension (<i>N</i>=16) in a primary care facility. A quantitative descriptive pre and post study design ascertained the effectiveness of the teaching intervention. Participants received face-to-face teach-back educational sessions accompanied by American Heart Association&rsquo;s <i>Understanding and Controlling your High Blood Pressure.</i> The Healthcare Effectiveness Data and Information Set (HEDIS) guideline and the Hypertension Knowledge-Level Scale (HK-LS) were valuable in measuring outcomes before and after the intervention. There was a statistically significant improvement in median HK-LS from pre-intervention (52% IQR: 36%, 66%), to post-intervention (95% IQR: 86%, 100%, Z=-3.521, <i>p</i> &lt; .001). Also, 50% of the participants met the HEDIS BP guidelines of BP less than 140/90 at post-intervention whereas none had met the target pre-intervention. The findings indicate the teach-back method to be effective in improving hypertension knowledge and BP control in this population. Healthcare providers should employ an easy to understand patient educational tool to optimize patient understanding and ability to adhere to their hypertension regimen.</p><p>
