Abstract

A system and method for managing patient medical information to facilitate data management and improve physician access to and recordal of examination data is described. The method comprises a computer aided process including the steps of scheduling appointments, entering and displaying data to a physician, updating the patient data with progress notes concurrently with an examination, displaying allergy warnings and recording a diagnosis based on the progress notes. A common graphic user interface is also disclosed to facilitate operation of the preferred system and method. The system and method are implemented with a relational database operating on data tables which store information input into the user interface.
