The Digital Doctor emerges from hibernation to discuss Clinical Wikis - with Wai Keong Wong and Marcus Baw. We discuss the case for using Wikis to manage local knowledge within a clinical environment - like ‘how to order X test’, ‘how to get your IT password set up’, and ‘how to refer to Y speciality…’. We also discuss the technical process of setting up a Wiki, moving from proof-of-concept stage to production, engaging IT staff in the change, capturing clinical enthusiasm and dealing with problems.
