Medication management is a daily and time-consuming task for hospital nurses. It includes searching for generic substitutions in online databases when a prescribed drug is not available, and also searching for specific drugs in the actual medication room to find where it is physically located. In co-creation with stakeholders an Augmented Reality-based companion was created, which resides in a holographic device that can be worn during practice and assists nurses through a holographic, mixed reality environment, supporting the task of medication management in a comfortable way. Ethical assessment of the system, conducted using the AI4EU assessment tool, highlighted key strengths of the system and also identified areas for improvement, particularly in transparency legislative clarity. A challenge for user testing in clinical environments is that hospital medication rooms are strictly regulated. To enable future user studies a Medication Room Simulator was developed.
