  • Publication number: 20200152332
    Abstract: Systems and methods are provided for healthcare predictive analysis based on dynamic monitoring of patient conditions. Dynamic monitoring is used by healthcare provider entities to collect historical claim feed data regarding its patients. The historical claim feed data is used to monitor patients' progress and conditions. Moreover, this data is used to train and update a predictive model used to predict the occurrence of events. The model predicts the occurrence of events using a sliding window-based algorithm, in which subsets (e.g., windows) of the historical claim feed data are sequentially used to train the model. For each window of data, the model extracts features and outcomes, and trains the model based thereon. The model then extracts features and outcomes of the next window of data and updates the existing model based thereon. The resulting model is run against a set of a data to predict the occurrence of events.

  • Publication number: 20190385715
    Abstract: The present disclosure pertains to computer-assisted linkage of healthcare records. In some embodiments, a first portion of a collection of healthcare records of individuals may be processed using a set of record attributes (corresponding to strong identifiers) that includes one or more record attributes corresponding to strong identifiers. Based on such processing, a first set of matches between healthcare records of the first collection portion may be predicted, and a number of matches in the first set of matches may be determined. At least one other portion of the collection of healthcare records of individuals may be processed using another set of record attributes that includes one or more record attributes different from the strong-identifier-corresponding record attributes. Based on the number of matches in the first set of matches, the processing of the other collection portion with respect to predicting healthcare record matches may be caused to stop.

  • Publication number: 20190147988
    Abstract: An electronic processor (14) is programmed to perform integration (16) of N anonymized healthcare databases (10). For in a pair of databases (i,j) of the N anonymized healthcare databases, a set of features is identified (44) each contained in both databases i and j of the pair of databases (i,j). A conversion table is generated (46, 48) that matches patients of the pair of databases based on patient similarity measured by the set of features. The identifying and generating operations are repeated (50) for each unique pair of databases of the N anonymized healthcare databases to generate N(N 1)/2 conversion tables (20). The electronic processor is further programmed to perform a patient data retrieval process (18) which receives a patient ID of a patient in one of the N anonymized healthcare databases and retrieves patient data for the patient contained in the N anonymized healthcare databases using the N(N?1)/2 conversion tables.
