Background: Self-monitoring of blood pressure (BP) clinically decreases BP. However, cost can limit access, especially in underserved populations. Objective: This mixed-methods pilot study aims to determine the impact of providing home BP monitors free of charge to patients at a federally qualified health center (FQHC) by quantifying the effect on BP and surveying patients to measure satisfaction and engagement. Methods: One hundred eighty patients with clinically diagnosed hypertension received BP monitors. Patient charts were reviewed to collect demographics and office BP readings 3 months before and after receiving a monitor. A 13-question phone survey was conducted to a sample of patients addressing satisfaction and engagement. Answers were based on a Likert scale and dichotomous yes/no. Results were analyzed with descriptive statistics and paired t tests. Results: The chart review demonstrated a significant mean decrease in systolic BP by 5.44 mm Hg (P < 0.001, -8.03 to -2.84) and a mean decrease in diastolic BP by 2.70 mm Hg (P < 0.001, -4.08 to -1.32) after the intervention. For those included who responded to the survey (13%), there was a significant mean increase in the frequency of checking BP per week by 1.5 Likert points (P < 0.00001, -1.0 to -1.9), and a majority (57.8%) felt slightly or much more active in their health care in addition to other benefits. Conclusion: Providing BP monitors to FQHC patients free of charge may have contributed to a significantly decreased office BP, improved engagement, and satisfaction. This program removed cost barriers and allowed patients to be more active in their health care.
