Abstract

A system processes medical information of multiple patients to provide data for use in supporting clinical decision making. The system includes an interface for receiving, from a remote source, data representing patient non-specific medical information excluding patient specific information. The patient non-specific medical information comprises medical information of multiple individual patients treated at one or more healthcare organization sites. A data processor automatically, parses the received data, identifies, within the parsed received data, site specific information associated with a particular healthcare provider organization site and facilitates identification of the particular healthcare provider organization site. The data processor removes the identified site specific information from the data representing patient non-specific medical information to provide both patient and site non-specific, patient medical information representative data and stores both the patient and site non-specific, patient medical information representative data in a repository.

15. A system for use by a healthcare provider in processing medical information of a plurality of patients to provide data for use in supporting clinical decision making, comprising:

a data processor for automatically processing received patient medical data by,

parsing said received patient medical data,

identifying, within said parsed received patient medical data, patient specific information associated with individual patients and facilitating identification of individual patients,

removing said identified patient specific information from said parsed received patient medical data to provide patient non-specific patient medical information representative data including related healthcare provider site information and

storing said removed identified patient specific information and said patient non-specific patient medical information representative data in at least one repository; and

a communication interface for communicating at least one of, (a) said removed identified patient specific information and (b) said patient non-specific patient medical information representative data, to a remote system in response to user command.

16. A system according to claim 15, wherein
