I need a PHP/MySQL electronic patient record system. A number of users would log in and add info on a patient. Each user would have access rights to different tables and would be able to add/delete/modify own data but not other users data. There would by 4 user groups. Needs clean interface. I already have basic table structures and basic PHP frontend that can be modified or rewritten from new. You may use an already existing system such as [url removed, login to view] which is an open resource software and make some modifications to it if necessary but I would prefer a system from scratch.
