Project Summary: OPEN EMR - Demo EHR system Chapter 12 general instructions. I will NOT be extending these assignments - so please make sure you have played with the DEMO EMR and are familiar with it so you can do these in one session. You can do these in separate sessions, but you will have to re-do all the previous work in order to put the patients back into the system so you can select them for the appointments. Do these in the order they appear here and in the Assignment Calendar. Matrix, create patients, then appointments.
