Patient data mining for quality adherence
First Claim
1. A system for automatically ensuring adherence to clinical guidelines, comprising:
- a data source containing at least one patient record, including a first record for a patient being treated, the first patient record including structured information mined from unstructured patient data by a processor, the unstructured patient data including free text, the structured information for the patient being treated comprising values for variables related to clinical actions for the patient being treated, each of the values inferred from pieces extracted, by mining, from the unstructured patient data for the patient being treated, the pieces for each variable assigned respective first probabilities of indicating respective possible values, different pieces indicating different possible values of the respective variable, a plurality of the first probabilities referring to a same one of the variables combined into a unified probability for the value for the same one of the variables, at least one of the first probabilities being less than 100%, the value for the same one of the variables determined from the unified probability, the pieces and possible values for each of the variables being for the patient being treated, at least one of the pieces extracted from the free text;
a guideline knowledge base containing a clinical guideline; and
a quality adherence engine for monitoring adherence with the clinical guideline as a function of the information mined from unstructured patient data in the first record for the patient being treated.

Abstract
The present invention provides systems and methods for automatically ensuring adherence to clinical guidelines during the course of patient treatments. A data source contains patient records, including records for patients being treated; a guidelines knowledge base contains clinical guidelines; and a quality adherence engine is configured to monitor adherence with the clinical guidelines for patients being treated. At least some of the patient records may include information obtained from mining unstructured patient data. The system includes an output component for outputting quality adherence information. The outputted quality adherence information may include reminders, including reminders to take clinical actions in accordance with the clinical guidelines. The outputted quality adherence information may also include warnings that the clinical guidelines have not been observed.

17. A method for automatically ensuring adherence to clinical guidelines during the course of patient treatments, the method comprising the steps of:
-
obtaining a patient record for a patient being treated, the patient record containing at least some structured information from a mined unstructured data source, the structured information comprising values for variables related to clinical actions for the patient being treated, the values for the variables inferred from pieces extracted, by processor mining, from the unstructured patient data source, the pieces for each variable assigned respective first probabilities for different possible values for the respective variable, a plurality of the first probabilities referring to a same one of the variables of the patient being treated combined into a unified probability for the value for the same one of the variables, at least one of the first probabilities being less than 100%, the value determined from the unified probability, the pieces and possible values being for the patient being treated, at least one of the pieces extracted from free text; retrieving a clinical guideline from a guideline knowledge base; and monitoring adherence to the clinical guideline for the patient being treated as a function of the information from the mined unstructured data source. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 29, 30, 31, 32)

28. A program storage device readable by a machine, tangibly embodying a program of instructions executable on the machine to perform method steps for automatically ensuring adherence to clinical guidelines, the method steps comprising:
-
obtaining patient records for patients being treated, at least some of the patient records containing information from mined unstructured data sources, the information for a first patient being treated comprising values for variables related to clinical actions, each of the values being from pieces extracted, by mining, from the unstructured patient data, each of the pieces for a same variable assigned first probabilities, a plurality of the first probabilities referring to the same one of the variables combined into a unified probability for the value for the same one of the variables, at least one of the first probabilities being less than 100%, the value determined from the unified probability, the pieces and values being for the patient being treated, at least one of the pieces extracted from free text of the unstructured data source; retrieving clinical guidelines from a guidelines knowledge base; and monitoring adherence to the clinical guidelines for the patients being treated as a function of the information from a mined unstructured data source.
