Background Delirium is frequently missed in clinical practice. We used a user-centred redesign process to evaluate and adapt an existing electronic delirium screening tool (eDIS-ICU) for use in the medical setting. Methods In phase 1, we conducted a brainstorming session to establish context for delirium screening tools in medicine. In phase 2, a pluralistic walkthrough of eDIS-ICU was performed to identify prospective usability in the medical setting. We then extracted positive and negative qualities of eDIS-ICU. In phase 3, recommendations for change were made. Results Pluralistic walkthrough highlighted that eDIS-ICU related to the key groups of functionality, diagnosis, links with management and potential integration with clinical information. Recommended changes to make eDIS-ICU suitable for use in a medical setting included the need for skip function, prior instructions and streamlined testing. Conclusion A human-centred redesign created a pilot electronic delirium screening tool for use in a general medical setting (eDIS-MED).
