  • Patient readmission prediction tool
    Patent number: 11250954
    Abstract: Facilities are provider herein for predicting potentially preventable patient readmissions after discharge from a health care provider. A patient readmission prediction model is built based on received patient data for one or more health care providers. Patient attributes discernible from that patient data are extracted and analyzed, and certain attributes are selected as being meaningful in predicting likelihood of post-discharge, potentially preventable patient readmission by patients newly admitted to a health care provider. Patient data for a newly admitted patient is obtained, and the readmission prediction model is applied against that patient data for the newly admitted patient to obtain a predictive risk score that is indicative of the likelihood that the newly admitted patient will experience a potentially preventable readmission post-discharge from the health care provider.
