Building a patient portal that was accessible from day one

The challenge

A healthcare provider needed a patient portal — appointments, results, secure messaging — that every patient could use, including those relying on screen readers, keyboard navigation or magnification. Accessibility could not be a retrofit: with the European Accessibility Act in force, the portal had to be conformant at launch, and a health service can never treat some patients as edge cases.

What we did

We designed to WCAG 2.2 AA from the first wireframe rather than auditing at the end. Semantic structure, keyboard operability, visible focus, and clear, specific error messaging were requirements in every component, tested with assistive technology as we built. The result is a portal that is calm, fast and usable for everyone — accessibility that reads as good design, not a compliance overlay.

Accessibility is often bolted on at the end of a build, discovered in a pre-launch audit, and fixed under time pressure. For a patient portal that is the wrong order entirely: the people most likely to depend on assistive technology are often the people who most need to reach their health information. We built this one the other way round — accessibility first, everything else in service of it.

Design to the standard from the first wireframe

We treated WCAG 2.2 AA as a design input, not a test at the end. Heading structure, landmark regions, colour contrast and focus order were decided while the interface was still a wireframe, so the accessible version was the design — not a parallel one to reconcile later. Every interactive component was built to be fully keyboard-operable, with a visible focus state and an accessible name, and validated with a screen reader as part of the same task that created it.

Make the essential flows calm and fast

The core journeys — booking an appointment, reading a result, sending a secure message — were rebuilt to load and respond instantly and to give specific, plain-language feedback when something went wrong. Sensitive, regulated steps kept every safeguard they needed; the friction that wasn’t doing a job came out. The portal ended up faster and clearer for all patients, which is the usual dividend of building accessibly: it is simply better design.

The figures here are illustrative of what this kind of accessibility-first web application work delivers; this is a representative, industry-level example and the client is not named. What carries across is the principle: design to the standard from the start, test with real assistive technology, and never treat any patient as an edge case.

If you’re building a product that has to be accessible — legally, or because your users depend on it — that’s the work our web development and design teams do together. Start a conversation.
