Tagging and Shared Global State - Two Hospital UIs

Sitting around in Grandma's hospital room I noticed two novel UI's...

1. Tagging - no not that kind of tagging. A perforated card with a string attached type of tagging. The UI is cool because it's easy to understand and impossible to screw up. Just tearing off the next segment leaves you with both an updated status and queued up to move to the next command.

2. Shared Global State - This turning chart insures that nurses are all synchronized about which side a patient should be on at any time of the day. It means that the local conditions don't need to evaluated - just do what the next state says to do.

Hospitals sure are filled with interesting design problems and novel solutions.

For those keeping track, grandma is feeling better, and may in fact be on the road to recovery.
