The Patient Data Management System operates under the control of a physician to implement a patient-specific instance of the apparatus which is capable of accessing at least one data manipulation module, each defining at least one process for transforming patient medical data pursuant to a predefined schema. A patient medical data processor is responsive to the physician selecting a set of patient medical data, at least one of the data manipulation modules, and an order of applying the selected data manipulation modules to the selected patient medical data for processing the selected patient medical data using the selected data manipulation modules in the selected order to identify data indicative of a predetermined condition in the selected patient medical data. A display is available for presenting a visualization of the data indicative of a predetermined condition in the selected patient medical data.
