DAApp: an app for patients with atopic dermatitis

The Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico Milano is an excellence in the field of research and treatment of dermatological diseases. With a particular focus on atopic dermatitis, the hospital is committed to improving the lives of patients suffering from this condition through the implementation of innovative solutions.

The Policlinico wanted to give patients with atopic dermatitis a tool to manage their therapy, designed above all for those on biologic drugs. With DAApp, patients keep an accurate record of their treatments and prepare their hospital visits from the app.

• On first access, patients fill in a detailed profile about their health and their needs.
• Before visits, the app asks them to complete a periodic questionnaire, so the medical staff come to the appointment with up-to-date information on how the therapy is going.
• The app keeps the history of past visits and upcoming appointments.
• Patients log the medication they use and the app automatically calculates the quantities they need.

We started with sketches and low-fidelity flows to compare different navigation structures and interface layouts. In the high-fidelity flows we then designed the final components and screens, paying close attention to usability and accessibility, because the app is used by very different patients.

The app is built in Flutter for Android and iOS. The APIs are written in Node.js, and patient data, which is sensitive, is stored in a PostgreSQL database.
