Effectiveness of Web Accessibility Policy Implementation in Online Healthcare Information.

UN have recommended the adoption of Web Content Accessibility Guidelines (WCAG) version 2.0 from W3C to guarantee that web content is more accessible to everyone. This study aims to evaluate the effectiveness of WCAG 2.0 implementation by comparing the country with and without WCAG2.0 policy adoption. The objective is to compare the impact of adopting the WCAG 2.0 standard in health information provision by analyzing the differences between countries that adopted the WCAG 2.0 standard and those that did not, specifically for health information related to the elderly. To this end, searches were performed on the Google search engine for online health websites with the keyword "Alzheimer" and the specific country settings for Indonesia and UK, in the local language of each country. Website evaluations were performed for ten websites found with this search by using the WCAG 2.0 measurement tool Axe. Statistical analysis using descriptive and Mann-Whitney analysis to measure the impact of the WCAG 2.0 showed a predominance of low violation occurrences in the UK with 40% from selected websites compared to 80% medium violation occurrences and no low violation occurrences in Indonesia. Although the country with WCAG 2.0 implementation had a lower frequency of violation, no significant differences were found between countries and the media type in WCAG 2.0 evaluation, implying the need to improve the effectiveness of policy implementation.
