US 2026/0074080 A1 · TRANSLATION OF MEDICAL EVIDENCE INTO COMPUTATIONAL EVIDENCE AND APPLICATIONS THEREOF

Abstract

A computational evidence platform extracts clinical concepts from medical evidence sources and creates a database of elemental diagnostic factors and elemental investigations links to medical conditions. Input from a person groups factors and investigations makes corrections and adds a ranking. Elemental factors and investigations do not include information specific to their associated conditions but include synonyms and a link to a medical ontology. A patient state is determined by extracting patient known diagnostic factors and investigation results from the patient chart. These known factors and results are matched to the database and a ranking of likely conditions are output. Next-best actions per condition are output by determining factors not yet known and investigations not yet performed. Next-best actions across conditions are determined by performing a recursive tree search of the database and assuming that unknown factors are now known to generate a score for each assumption.

Dependent claims

A method of querying a knowledge graph, said method comprising:

receiving, via an application programming interface (API), a medical query from a software application for querying said knowledge graph, wherein said knowledge graph includes a plurality of medical condition nodes and a plurality of diagnostic factor nodes, each of said diagnostic factor nodes being linked to at least one of said medical condition nodes;
using a code in one of said diagnostic factor nodes, following a link to a factor within an electronic medical ontology corresponding to said one of said diagnostic factor nodes, and traversing within said electronic medical ontology to obtain a result;
using said result from said traversing, matching a portion of said medical query to at least one of said medical condition nodes or to at least one of said diagnostic factor nodes to produce an output;
and
outputting, responsive to said medical query, said output to said software application.

2 more elements

A system for querying a knowledge graph, said system comprising:

a database that stores a knowledge graph including a plurality of medical condition nodes and a plurality of diagnostic factor nodes, each of said diagnostic factor nodes being linked to at least one of said medical condition nodes;
a computer system comprising one or more processors and memory that stores instructions, wherein the instructions, when executed by the one or more processors, cause the one or more processors to:
receive, via an application programming interface (API), a medical query from a software application for querying said knowledge graph;
use a code in one of said diagnostic factor nodes to follow a link to a factor within an electronic medical ontology corresponding to said one of said diagnostic factor nodes, and traverse within said electronic medical ontology to obtain a result;
use said result from said traverse and match a portion of said medical query to at least one of said medical condition nodes or to at least one of said diagnostic factor nodes to produce an output;
and
output, responsive to said medical query, said output to said software application.
