Redesign of a medical tool
Goal
In 2019, Unisanté developed a clinical decision support tool for its physicians abroad. This medical software was designed to improve diagnostic efficiency and the quality of care for over one million children treated in health centers in Tanzania and Rwanda.
Over time, a complete UX/UI redesign of the software became essential to ensure a smooth user experience tailored to the needs of medical staff.
Approach
I divided the project into six phases, which allowed me to understand the current context of the tool, gather key insights from users, propose a new version, and design the entire application.

Medical tool
My work began with a research phase, including an audit of the tool, field observations, and user interviews to identify pain points and clinicians’ needs.
This stage also helped me familiarize myself with the medical environment and the complex terminology used within the tool.
I gathered key insights and formulated initial hypotheses: The medical jargon in the interface made certain tasks confusing, the navigation was illogical, leading to wasted time for clinicians and he UI lacked clarity: unintuitive design, confusing colors, and poor emphasis on primary actions.
01
Project Framing
Ergonomic audit, usage analysis, user testing, and interviews with medical teams
02
User research
In-depth user research, qualitative interviews, creation of personas, and analysis of specific needs
03
UX Design
Desktop and mobile wireframes, validated with user testing to ensure ergonomics and intuitiveness
04
Wireframing
Conception UX avec des wireframes desktop et mobile, tests utilisateur·trices pour valider l’ergonomie et l’intuitivité de l’interface
05
Design UI
Creation of graphic elements, development of a coherent and accessible design system aligned with the medical field
06
Prototyping
Interactive prototypes, validation with stakeholders, and adjustments before final development
Ontology, site map and task flow
I worked extensively on language clarity. By conducting card sorting workshops with clinicians, we were able to establish a clear and validated nomenclature.
Once validated, I defined the main user flows and translated them into mid-fidelity wireframes. These were tested and approved by users. Given the tool’s complexity, validating the structure was crucial before moving on to the visual design.
UX Design
Last but not least,
I moved on to the UI design. The old interface had no defined design system, so I created a new visual identity — clean, consistent with Unisanté’s branding, and adapted to the medical environment.
I produced all high-fidelity screens, supported by an interactive prototype that conveyed the application’s look & feel while illustrating interactions for developers.
I also delivered the necessary documentation to ensure developers could work independently during implementation.
After my involvement, the tool was successfully developed and implemented. Today, it is still in use by clinicians.
The project was awarded the Bachelor’s Prize of Excellence, and the tool also won the Best of Swiss Web Award (Technology category, 2022).
