Table 2: Platform web pages from the patient’s perspective. 5. Manual review with WCAG 2.1: During this phase, web accessibility experts conduct a detailed manual review of the selected web pages. The examination covers various aspects, including providing alternative text for images to ensure accessibility for visually impaired users, assessing keyboard navigation, and verifying compatibility with screen readers. The manual review identifies accessibility gaps and recommends enhancing the platform's compliance with WCAG 2.1. 6. Documentation of issues and recommendations: All identified accessibility issues and corresponding recommendations from automated and manual reviews are meticulously documented. Each issue is detailed, including its nature, location, and potential impact on user accessibility. 7. Implementation of improvements: Necessary modifications are made to the patient web pages to address identified accessibility issues and align with the standards set by WCAG 2.1. This phase focuses on implementing recommended improvements to resolve accessibility problems detected in the platform's patient web pages. 8. Verification: A final verification ensures the implemented improvements effectively resolve the accessibility issues identified in the previous phases. This verification process aims to validate that the platform attains the AA level of accessibility, meeting the standards established by WCAG 2.1. 9. Documentation of results: The results of the accessibility evaluation, comprising identified issues, implemented improvements, and any other relevant findings, are documented for future reference and monitoring [32]. Significant progress has been observed in resolving serious and contrast errors, which were not identified during the automatic evaluation. Additionally, the platform has achieved a compliance level of 95.1% in alerts, 93.6% in characteristics, and 93.4% in structural elements, as illustrated in Figure 8.  
The selection of accessibility standards and guidelines implemented in digital health platforms significantly influences the enduring nature of web accessibility within the healthcare domain.
