I'm not sure whether these things deserve their own category. After all, writers always tailor their work to different formats: sometimes you write a lot, sometimes you write a little, even in print. Anyway, here's an example.
An agency launching a novel treatment for skin cancer was faced with a dilemma: the product was suitable for use in primary care but GPs' diagnostic skills and referral pathways could have been better. I was commissioned to author a training package for distribution on CD-ROM that would cover diagnosis, management and information for patients without a promotional message. The agency had a clear brief and lot of the necessary information, so I had only a little research to do. The presentation comprised short videos and stills. I wrote the scripts and prepared drafts of the graphics.
sixpartswater.org was conceived as a medical site with a difference - the aim was to involve members of the public worldwide. I wrote some plain-talking features on knotty subjects like colds and flu, managing anticoagulation and self-monitoring diabetes. A refreshing change not to use jargon.
