Prescribing Module

Proposal to clean up and add additional functionality

1. Change interface/patient_file/summary/rx_frameset.php to only show one frame (remove interface/patient_file/summary/rx_left.php)
   • Will need to add a 'Add New' prescription to templates/prescription/general_list.html first.
2. Migrate all stuff from templates/prescription/general_send.html to templates/prescription/general_list.html
   • Then can remove templates/prescription/general_send.html
3. Now the templates/prescription/general_list.html will be the central Rx page, and can place all functionality such as relaying, refills, on this page; could do anything here using javascript, php etc..
4. To add a new function to this templates/prescription/general_list.html page, recommend placing the function in controllers/C_Prescription.class.php and then calling it.
   • For example a function 'relay' would be labeled relay_action in controllers/C_Prescription.class.php, and called as so:

     • http://opensourceemr.com/openemr/controller.php?prescription&relay&(variables here)

   • If you follow this then you will ensure it won't break connections to other places in OpenEMR (ie. the drug dispensary module, mapping to drug dosages etc. stored in database, reports); because of all these inter-relationships, I've concluded that rebuilding from scratch is a bad idea.
5. Could do same to add interactions, lookups, allergy checks in templates/prescription/general_edit.html
