The Problem
Getting a diagnostic test done is only half the problem. Getting your results in a way you can actually understand and act on was still deeply broken for most BeaconHealth patients.
Results were delivered inconsistently: sometimes physical printouts, sometimes phone calls, often delayed. Patients had no way to access their history, share results securely with another doctor, or track their health over time.
The design challenge was compounded by context. Users ranged from highly educated urban professionals to patients with lower digital literacy in peri-urban areas. The solution had to work across that full spectrum, on low-end Android devices, on slow connections, with varying levels of health literacy.
The old patient journey: test done, results unreachable
The Approach
The guiding principle was radical simplicity. Every feature, every screen, every label was stress-tested against one question: would someone with low health literacy understand this without help?
I prioritised the critical path ruthlessly: log in, see your results, understand what they mean, share or download. Everything else was secondary. The result interpretation layer was particularly important, translating clinical values into plain-language summaries without overstepping into medical advice.
The patient result view, designed for all literacy levels
Security and privacy were non-negotiable. Diagnostic data is sensitive and patients needed to trust that their results were theirs alone. Authentication flows, result-sharing permissions, and data visibility were all designed with explicit patient control at the centre.
I also designed with bandwidth constraints in mind. The product had to load fast on 3G, display cleanly on budget Android phones, and never require a patient to ask for help.

Reflection
Designing for a broad Nigerian user base taught me that accessibility is not just about screen readers and contrast ratios. It is about cognitive load, trust, and context.
A patient seeing their blood work on a mobile screen for the first time needs a completely different experience than a clinician viewing the same data. Holding both users in mind simultaneously, across the same data set, made this one of the most nuanced design problems I have tackled.
