Cardio SEM: A Novel Approach for a Traffic Light System for Heart Failure Warning Signs.

Existing literature on the follow-up of heart failure patients with warning signs shows that it is necessary to increase patients' knowledge and of seeking help in a timely manner. This suggests an opportunity to implement strategies that integrate technology to visualize the risk of decompensation. This article studies the acceptance of Cardio Sem, a traffic light system mobile application for patients with heart failure. A descriptive, observational pilot study was performed with 23 outpatients belonging to a heart failure program. For 4 weeks, patients used Cardio Sem, which allows visualizing the risk of decompensation through a series of questions that patients must answer daily and provides guidance for managing signs and symptoms of decompensation. A technology acceptance questionnaire was applied to all patients, resulting in acceptance of the application, especially in the dimensions that emphasized perceived usefulness (100%), social influence (100%), and behavioral intent (99.8%). Cardio Sem is useful for early detection of symptoms that allow for early response to complications. Acceptance of the application by patients and its ease of use present the possibility to implement it as a complementary tool to promote self-care and effective management of symptoms.

Digital Health Literacy in Patients With Heart Failure in Times of Pandemic.

This study sought to determine the effect of a digital health literacy program regarding knowledge and skills in the use of digital resources related to self-care and health empowerment for patients with heart failure. A cross-sectional pilot study was conducted before and after the program in patients (n = 28) with heart failure at a tertiary care center. Both a knowledge test and the Health Empowerment Scale were used with a Cronbach's α of 0.89. The information was processed using the statistical software Restudio, which allowed us to make a descriptive and inferential analysis. Seventy-five percent of the participants were men with an average age of 68 years, 60.7% had elementary schooling, 71.4% had preserved ejection fraction, and 57.6% had a family member as a caregiver. A statistically significant change ( P < .005) was found in the level of empowerment and the knowledge and skills in the use of digital resources applied in health. The results showed that the digital health literacy program is a cost-effective intervention that nursing professionals must integrate into continuity of care, not only in pandemic times but also in a permanent and standardized manner. An empowered patient with knowledge and skills in the use of digital resources is a patient with the ability to decide, satisfy needs, and solve problems, with critical thinking and control over their health.
