Systems and methods for medical information analysis with deidentification and reidentification

In a medical information navigation engine, a method for quality optimization useful in association with at least one electronic health record system, the method comprising:

• decoupling identifying information from clinical data from at least one electronic health record system, wherein the clinical data includes clinical narrative having discrete data and textual data;
• storing the identifying information, wherein the identifying information is associated with a token in the clinical data;
• indexing the clinical data;
• mining the discrete data and the textual data, wherein the mining includes extracting at least one relevant event from the discrete data and the textual data;
• reintegrating the clinical data with the identifying information using the token;
• decoupling the identifying information from the clinical data for a plurality of electronic health records for a cohort of patients and encrypting the identifying information for the cohort using a single encryption scheme;
• and
• wherein the cohort includes at least one of demographics, genotype, and phenotype.

A medical information navigation engine, useful in association with at least one electronic health record system, the medical information navigation engine comprising:

• a processor configured to decouple identifying information from clinical data from at least one electronic health record system, wherein the clinical data includes clinical narrative having discrete data and textual data;
• a database configured to store the identifying information, wherein the identifying information is associated with a token in the clinical data;
• an indexor configured to index the clinical data;
• the processor further configured to mine the discrete data and the textual data, wherein the mining includes extracting at least one relevant event from the discrete data and the textual data;
• and
• the processor further configured to reintegrate the clinical data with the identifying information using the token;
• and
• the processor further configured to identify at least one coding opportunity associated with at least one patient condition mined from unstructured clinical data, wherein the at least one patient condition has not yet been associated with one of the patient claims.
