ACESSIBILIDADE DIGITAL PARA PESSOAS COM BAIXA VISÃO NO APLICATIVO MEU SUS DIGITAL: DESAFIOS E PERSPECTIVAS

Abstract

The digital transformation of public health services has promoted significant advances in access to medical care in Brazil. The Meu SUS Digital application, launched in 2022 by the Ministry of Health, represents a milestone in the digitization of the Unified Health System (SUS), with more than 50 million downloads. However, issues related to digital accessibility for people with low vision remain critical challenges for effective digital inclusion. This study aims to analyze the challenges of digital accessibility for users with low vision in the Meu SUS Digital application. The methodology adopted is characterized as qualitative research of an exploratory-descriptive nature, based on automated technical analysis using the Accessibility Scanner (Google), practical tests with native Android accessibility settings, and heuristic evaluation based on WCAG 2.1 and eMAG 3.1 guidelines. The results revealed critical accessibility deficiencies, with an overall compliance rate of only 40% in relation to WCAG 2.1 guidelines. Eleven color contrast violations were identified in 63.6% of the analyzed screens, with extremely critical cases showing contrast up to 24 times lower than recommended. Additionally, 12 elements presented inadequate size for interaction, significantly compromising usability. The most impacted functionalities include the Vaccines section, with severe compromise, and the Exams menu, with critical compromise. It is concluded that the application, in its current state, digitally excludes approximately 7.2 million Brazilians with low vision, violating the Brazilian Inclusion Law and compromising equitable access to essential public health services. The immediate implementation of critical contrast corrections, resizing of interactive elements and adequate support for magnification is recommended, in addition to structural improvements in the development process to ensure continuous compliance with accessibility guidelines.
