The very first screen you see upon signing in is the Open Charts screen. Much like a chart pulled from a real file cabinet, Open Charts are available for viewing and creating items (encounters, Rx's, reports, etc). When you are done with a chart, it is "closed" and removed from the Open Charts screen. You close a chart by right-clicking the name and selecting "Close Chart". You can only close a chart that has all encounters, reports and notes finalized (except for the Sample Patient, which does allow immediate closing).
If a patient has a photo entered in the demographics screen, click the name ONCE to view the image.
