  • Publication number: 20050246330
    Abstract: A method for determining a blocking key includes selecting, randomly, a plurality of record pairs from a pair space that can be formed from a plurality of records of a database, scoring the plurality of record pairs, and comparing a score of each of the plurality of record pairs to a threshold to determine a label for each record pair. The method further includes comparing, character-by-character, each field of each of the plurality of record pairs, wherein a result of the comparison is a binary vector entered in a binary vector matrix, and determining a blocking key based on the binary vector matrix.

  • Publication number: 20050137910
    Abstract: Systems and methods for automated processing of medical information in electronic patient medical record databases, wherein billing information (e.g., diagnosis codes, procedural codes) is automatically extracted from electronic patient medical records through comprehensive analysis of clinical information included in the patient medical records using a knowledge base of domain-specific criteria. The extracted billing information can be automatically processed for purposes of, e.g., medical claims correction, medical claims billing, quality assurance of recorded billing information, or claim reimbursement tracking.

  • Publication number: 20030125984
    Abstract: A technique is provided for automatically generating performance measurement information. At least some of the obtained performance measurement information may be derived from unstructured data sources, such as free text physician notes, medical images, and waveforms. The performance measurement may be sent to a health care accreditation organization. The health care accreditation organization can use the performance measurement to evaluate a health care provider for its quality of patient care. Alternatively, performance measurement information can be provided directly to consumers.

  • Publication number: 20030126101
    Abstract: A method and system for determining patient states is provided. The method includes the steps of data mining a patient record using a domain knowledge base relating to a disease of interest; inputting the mined data into a model of the disease of interest; and determining a state of the patient based on the model. The system includes a data miner for mining information from a patient record using a domain knowledge base relating to a disease of interest; and a processor for creating a patient model of the disease of interest, processing the mined data in the model to determine a current state of the patient and future states for different courses of treatment, and recommending a therapy based on the determined future state.

  • Publication number: 20030125985
    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.

  • Publication number: 20030120458
    Abstract: The present invention provides a data mining framework for mining high-quality structured clinical information. The data mining framework includes a data miner that mines medical information from a computerized patient record (CPR) based on domain-specific knowledge contained in a knowledge base. The data miner includes components for extracting information from the CPR, combining all available evidence in a principled fashion over time, and drawing inferences from this combination process. The mined medical information is stored in a structured CPR which can be a data warehouse.
