OpenClinica Accessibility Policy

Updated November 15, 2022

OpenClinica web application accessibility

We want as many people as possible to be able to use the OpenClinica application, and OpenClinica is committed to ensuring digital accessibility for people with disabilities. We are continually improving the user experience for everyone and applying the relevant accessibility standards.

Accessibility-friendly design principles used in the OpenClinica application include:

  • Hyperlinks and icons to navigate
  • Responsive forms that can be used on standards-compliant browsers and across devices
  • Use of contrasting color. Use of color in combination with shape in order to distinguish icons.
  • Text alternatives for icons
  • Avoid displaying text as an image
  • Straightforward, table-based layouts
  • Tab-based navigation through form fields
  • Resizable text using control key and scroll wheel
  • Fully responsive participant-facing user experience
  • Structured page headings and labels
  • Text-based error messages; context sensitive help
  • Use of standardized, basic terminology
  • Clear all data in a form in a single step
  • Search feature to search for participants, which reduces the numbers of clicks and amount of scrolling
  • No flashing lights, sounds, or animated content

Standards Conformance 

The Web Content Accessibility Guidelines (WCAG) defines requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. Although our goal is WCAG 2.1 Level AA conformance, we have also applied some Level AAA Success Criteria: Images of text are only used for decorative purposes. Re-authentication after a session expires does not cause loss of data.

Technical specifications

Accessibility of OpenClinica relies on the following technologies to work with the particular combination of web browser and any assistive technologies or plugins installed on your computer:

  • HTML
  • CSS
  • JavaScript

These technologies are relied upon for conformance with the accessibility standards used.

Limitations and alternatives

Despite our best efforts to ensure accessibility of the OpenClinica application, there may be some limitations:

  • The OpenClinica application is designed to be compatible with the following web browsers: Chrome, Edge, Firefox, and Safari.
  • Depending on how a particular clinical study is configured, parts of the application may not be accessible to certain users with specific needs. For example, administrators building studies can include video and images without alt text.
  • User-supplied media content (for example, uploaded images) may not have text alternatives.
