Systems and methods utilizing natural language medical records
First Claim
1. A system for managing information, the system comprising:
- a means for capturing text from a document source;
a means for determining the structure of the captured text;
a means for extracting elements of data from the captured text;
a means for categorizing the extracted elements of data;
a means for normalizing the extracted elements of data;
a means for adding metadata relating to the captured text;
a means for validating the extracted elements of data and the metadata, wherein the means for validating further includes validating at least one of the normalized extracted elements of data and the categorized extracted elements of data;
a storage means for storing an electronic document including the categorized, normalized and validated extracted elements of data and metadata in a storage means, wherein the categorized, normalized and validated extracted elements of data and metadata are stored in association with the captured text; and
a means for retrieving the electronic document from the storage means.

Abstract
The invention involves systems and methods for generating, manipulating, summarizing, storing, reusing, and searching electronic medical records. Structured input of medical information by medical personnel based on templates may optionally be used to facilitate analysis of records, while allowing less restrictive text input than systems of the prior art. Data extraction of relevant medical data from the input text may optionally be facilitated by the structured format of the medical records. Extracted medical data is optionally validated and linked or associated with the text from which it was extracted. The extracted medical data is normalized to allow easier searching than available in systems of the prior art. Medical and document metadata is incorporated into the extracted medical data. Particularly pertinent medical information may be extracted and summarized from a patient'"'"'s medical history for use by a medical professional at the point of care.

51. A method, the method comprising the steps of:
-
entering information text in a predetermined record template, wherein text pertinent to a section of the template is entered in that section as natural language;
storing a completed medical record;
extracting elements of medical data from the text, wherein information about which section of the template the text was entered is used to extract elements of medical data from the text;
validating extracted data;
normalizing the extracted elements of medical data;
storing an electronic medical record as normalized extracted elements of medical data in association with the text from which they were extracted; and
retrieving electronic medical records from the storage means by natural language searching, wherein the retrieving is accomplished by reference to one or more extracted elements and the natural language is normalized. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67)
