Evaluation of the usability of the Quali+ mobile application for people with high blood pressure

Abstract

Objective: To evaluate the usability of the “Quali+”mobile application prototype for people with high blood pressure. Method: Descriptive, cross-sectional study of heuristic evaluation of a mobile application prototype carried out between June and July 2021, in a university hospital. Participants were 22 people with arterial hypertension in the city of Campina Grande, PB, Brazil. To measure usability, the Smartphone Usability questionnaiRE instrument was applied. Levels ≥70 points have good usability. Descriptive statistics were used. Results: The overall usability average was 105.8±7.44 points, with the lowest score being 83 and the highest being 113. Usability was at the highest level(80 points). Conclusion: The usability evaluation showed that, although it is a prototype, the application has good usability and can be considered for routine use in health self-management. Future research is needed to verify its effectiveness.
