In learning we often look in turn for role models, exemplars then even some comparator or examples against which to compare and contrast to understand the context and our own knowledge, skills and potential.
In health and social care information systems it's useful for me to look at what is available in Drupal. A recent find is Care2X with a demo available. There are numerous plans to take these systems further:
Care3g is seeking funding.
There is also Project Mtuha.
There's a post by Tim Schofield - Helping African hospitals with open source software that describes how the enterprise resource planning system KwaMoja @KwaMoja is being used to provide administration systems for hospitals in Africa.
Even though not on the same scale as commercial hospital systems in the USA and EU ... these are significant software projects compared with my purposes which are educational.
