Abstract

Background: Chronic heart failure (HF) is a complex and costly disease. Daily weight and symptom monitoring is the cornerstone of HF management. Little information exists about feasibility of a mobile monitoring intervention among minority patients with HF. Methods: We developed and tested usability of a mobile-monitoring system in minority patients with HF in a 2:1 randomized controlled trial. We tracked usage and obtained feedback on usability and the system overall at 1, 2, and 3 months. Results: Forty-two participants aged 53.0 ± 9.4 years (mean ± standard deviation) were randomized to the mobile-monitoring intervention group. They included the following: 67% males, 76% White Hispanics, 21% African Americans, and 52% with high school education or less. Over the 3-month intervention period, 26 (62%) participants used the system over 50% of the time. Overall, on a 1.0-7.0 scale for both, program satisfaction scores were excellent (mean 6.84 ± 0.46), and the usability ratings were all above 6.0. Comparing 1-to 3-month responses, there was a substantial increase in the percentage of participants who felt the system was easy to use after they had gotten used to it (84% vs. 94%) and that navigating the system was not complicated (78% vs. 84%). Almost all participants said that the program made them feel more secure about their health and that they would stay enrolled in a program like this. None of them had used a similar system before. Conclusions: A mobile phone-based disease management program is feasible in a minority county hospital population and offers a modality to help reduce ethnic disparity.
