Abstract

A term base can be used to index a raw medical term (e.g., a text string from an electronic health record) to generate a computational expression of the raw medical term. The computational expression of the raw medical term can be used to generate a uniform medical term for the raw medical term. The computational expression can be compared with other computational expressions to organize the electronic health record, filter the electronic health record, and provide a uniform presentation of raw medical terms from different events in the electronic health record.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
establishing, by a mobile user device and responsive to a first user selection of a first user interface element associated with a first electronic health record system, a first persistent connection pipeline with a first gateway of the first electronic health record system using an electronic health record system code associated with the first electronic health record system, wherein the electronic health record system code is configured for the mobile user device to connect to the first electronic health record system, and wherein the first persistent connection pipeline enables delivery of existing first electronic health data of a user account and future first electronic health data of the user account from the first gateway to the mobile user device;
receiving, by the mobile user device and directly from the first gateway over the first persistent connection pipeline, a first data package including a first electronic health record of the user account of the mobile user device, the first electronic health record including first raw medical data that is unique to the user account of the mobile user device and formatting according to a first format;
maintaining, by the mobile user device, the first persistent connection pipeline with the first gateway using a refresh token associated with the first electronic health record system, wherein the refresh token enables the mobile user device to maintain the first persistent connection pipeline without reauthentication of the mobile user device;
establishing, responsive to a second user selection of second user interface element associated with a second electronic health record system, a second persistent connection pipeline with a second gateway of the second electronic health record system, wherein the second persistent connection pipeline enables delivery of existing second electronic health data the user account and future second electronic health data of the user account from the second gateway to the mobile user device;
receiving, by the mobile user device and directly from the second gateway over the second persistent connection pipeline, a second data package including a second electronic health record of the user account of the mobile user device, the second electronic health record including second raw medical data that is (i) unique to the user account of the mobile user device, (ii) distinct from the first raw medical data, and (iii) formatted according to a second format that is distinct from the first format, wherein each of the first raw medical data and the second raw medical data comprises three or more of allergy data, medical condition data, immunization data, lab data, vital data, medication data, or medical procedure data, wherein the first electronic health record system is hosted by a first remote server and the second electronic health record system is hosted by a second remote server that is distinct from the first remote server;
storing, by the mobile user device, the first and second raw medical data in a data storage device on the mobile user device according to a first data model;
extracting, by the mobile user device, first and second raw medical terms from the first and second raw medical data stored in the data storage device of the mobile user device, each of the first and second raw medical terms including a text string;
indexing, by the mobile user device, each of the first and second raw medical terms by at least:
decomposing the respective text string corresponding to the respective raw medical term into a plurality of medical words present in the respective text string;
determining, using a medical topic rule, a medical topic to which each of the first and second raw medical terms belong, the medical topic including a plurality of predefined medical categories that are distinct from the medical topic;
for each respective medical word of the respective plurality of medical words, assigning, using the medical topic rule, the respective medical word to a predefined medical category of plurality of predefined medical categories based at least in part on a comparison of the medical word with other medical words represented in the predefined medical category;
determining, for each respective medical word, a uniform item descriptor corresponding to the respective medical word based at least in part on the predefined medical category;
converting, based at least in part on the uniform item descriptor, each respective medical word into a numerical code that represents the respective medical word; and
generating a medical term expression by at least combining each numerical code representing the corresponding medical word, each medical term expression representing the raw medical term in a quantifiable format;

storing, by the mobile user device, the medical term expression in the data storage device on the mobile user device according to a second data model that is distinct from the first data model; and
responsive to a request to view information associated with the predefined medical category, using respective first and second medical term expressions to present a single uniform medical term in a single format, wherein the single uniform medical term is distinct from the first and second raw medical terms and represents both the first and second raw medical terms.

2. The computer-implemented method of claim 1 , wherein the numerical code is a term base identifier that represents one or more indexed terms stored in a term base on the mobile user device, and the medical term expression is a medical term index including more than one term base identifiers.

3. The computer-implemented method of claim 1 , further comprising generating a data object that associates constitute parts of the raw medical term with the medical term expression, the data object useable to reproduce the first raw medical term from the medical term expression.

4. The computer-implemented method of claim 1 , wherein:
indexing each of the first and second raw medical term further comprises tokenizing the respective plurality of medical words to create a plurality of composite medical words representing sequence groupings of the respective plurality of medical words; and
converting each respective medical word into a numerical code is further based at least in part on the plurality of composite medical words.

5. The computer-implemented method of claim 1 , further comprising using the medical term expression to generate the single uniform medical term.

6. The computer-implemented method of claim 1 , wherein the second data model comprises a relational graph.

7. The computer-implemented method of claim 1 , further comprising identifying a plurality of item descriptors present in the predefined medical category, each item descriptor corresponding to an item.

8. The computer-implemented method of claim 1 , wherein each numerical code is unique with respect to other numerical codes.

9. A computer-implemented method, comprising:
establishing, by a mobile user device and responsive to a set of user selections of a set of user interface elements associated with a set of electronic health record systems, first and second persistent connection pipelines with a first gateway and a second gateway of a respective first electronic health record system and a respective second electronic health record system of the set of electronic health record systems using first and second electronic health record system codes respectively associated with the first electronic health record system and the second electronic health record system, wherein each electronic health record system code is configured for the mobile user device to connect to the res
