Patient data mining for cardiology screening
View Patent ↗A system and method for screening for coronary heart disease is provided. The method includes the steps of retrieving a test for assessing risk of coronary heart disease, the test including a plurality of data fields relating to coronary risk factors; accessing a database to populate the data fields with information of an individual patient; and calculating a risk assessment of the individual patient developing coronary heart disease. A system includes a first database including a plurality of structured computerized patient records; a second database including a knowledge base relating to coronary heart disease, the second database including at least one test for determining coronary heart disease risk; and a processor for retrieving the at least one test from the second database, populating the at least one test with patient information retrieved from the first database and calculating a risk assessment for at least one patient.
1. A method for screening for coronary heart disease, the method comprising the steps of:
retrieving a test for assessing risk of coronary heart disease, the test including a plurality of data fields relating to coronary risk factors;
accessing a database to populate the data fields of the test with patient information of an individual patient, the patient information being from computerized patient records having an unstructured data source;
calculating a risk assessment of the individual patient developing coronary heart disease as a function of the patient information in the data fields;
using a processor, performing as a function of the patient information in the data fields, a sensitivity analysis on the coronary risk factors of the individual patient to determine which factor will have the greatest effect in influencing the risk assessment; and
creating a model of a coronary heart disease patient to simulate effects of different variables to perform the sensitivity analysis.
2. The method as in claim 1 , wherein the model is based on medical knowledge of a disease of interest.
3. The method as in claim 2 , wherein the model is based on information mined from population-based data sources of patients exhibiting coronary heart disease.
4. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for screening for coronary heart disease, the method steps comprising:
retrieving a test for assessing risk of coronary heart disease, the test including a plurality of data fields relating to coronary risk factors;
accessing a database to populate the data fields of the test with patient information of an individual patient, the patient information being from computerized patient records having, at least in part, an unstructured data source;
calculating a risk assessment of the individual patient developing coronary heart disease;
performing, as a function of the patient information in the data fields, a sensitivity analysis on the coronary risk factors of the individual patient to determine which factor will have the greatest effect in influencing the risk assessment; and
creating a model of a coronary heart disease patient to simulate effects of different variables to perform the sensitivity analysis.
