User-centered design of a mobile medication management

Area of Science:

• Health Informatics
• Human-Computer Interaction
• Patient Safety

Background:

• Germany's nationwide medication plan is paper-based, leading to safety concerns.
• An electronic alternative could address the limitations of the current paper system.

Purpose of the Study:

• To develop a mobile interface concept for managing medication information.
• To explore the potential of digital solutions for medication management.

Main Methods:

• Human-centered design (UCD) process was employed.
• Analysis of use context, persona development, and interaction concept design.
• Paper and medium-fidelity prototypes were developed and evaluated by experts and end-users using think-aloud tests and the System Usability Scale (SUS).

Main Results:

• An interface design concept was developed for a specific user persona.
• The concept achieved an average SUS score of 92.1 in user testing.
• Identified usability issues were resolved, finalizing the design for future implementation.

Conclusions:

• The developed mobile interface concept shows high usability for medication management.
• The UCD approach provides a transferable framework for developing similar health applications.
• This digital solution has the potential to enhance patient safety by improving medication management.
