  • Publication number: 20240428194
    Abstract: A clinical documentation improvement (CDI) smart scoring method may include predicting, via per-condition diagnosis machine learning (ML) models and based on clinical evidence received by a system, a probability that a medical condition is under-documented and, via per-condition documentation ML models and based on documentation received by the system, a probability that a medical condition is over-documented. The under- and over-documentation scores are combined in view of special indicators and queryability factors, which can also be evaluated using ML query prediction models, to generate an initial CDI score. This CDI score can be further adjusted, if necessary or desired, to account for factors such as length of stay, payer, patient location, CDI review timing, etc. The final CDI score can be used to prioritize patient cases for review by CDI specialists to quickly and efficiently identify meaningful CDI opportunities.

  • Publication number: 20240303673
    Abstract: Fraud detection model performance is represented as compressed data in the form of polynomial curve coefficients. A data compression setting, a set of independent variable values, and a set of dependent variable values are used in polynomial regression to generate coefficients of a polynomial curve. The data compression setting is related to the order of the polynomial, for example set to the degrees of freedom (DOF) defined as the polynomial order. A lower DOF yields a higher error, but with a higher degree of compression. The lowest DOF with a tolerable error is selected and the polynomial coefficients are transmitted to a remote node. The remote node regenerates the polynomial curve for comparison with a polynomial curve from a prior time period, in order to determine a performance trend. The trend is used to either generate an alert or trigger further training of the fraud detection model.

  • Patent number: 11955213
    Abstract: In clinical documentation, mere documentation of a condition in a patient's records may not be enough. To be considered sufficiently documented, the patient's record needs to show that no documentation drop-offs (DDOs) have occurred over the course of the patient's stay. However, DDOs can be extremely difficult to detect. To solve this problem, the invention trains time-sensitive deep learning (DL) models on a per condition basis using actual and/or synthetic patient data. Utilizing an ontology, grouped concepts can be generated on the fly from real-time hospital data and used to generate time-series data that can then be analyzed by trained time-sensitive DL models to determine whether a DDO for a condition has occurred during the stay. Non-time-sensitive models can be used to detect all the conditions documented during the stay. Outcomes from the models can be compared to determine whether to notify a user that a DDO has occurred.
