Abstract: Various disclosed embodiments include methods and systems for population health risk stratification. The population comprises a plurality of patients. The method includes determining clinical risk factors of the plurality of patients from the patients' clinical data. The method includes determining utilization risk factors of the plurality of patients. The method includes determining compliance risk factors of the plurality of patients, wherein the compliance risk factors are determined from appointment compliance factor, referral compliance factor and medication compliance factor. The method includes determining health risk scores of the plurality of patients from the clinical risk factors, the utilization risk factors and the compliance risk factors. The method includes classifying population health risks based on the health risk scores.

Abstract: Various disclosed embodiments include methods and systems for determining a plurality of patients' risk of hospitalization and for forecasting healthcare cost. The method includes receiving a plurality of patients' clinical data from encounters over a predetermined time period and mapping disease codes in the clinical data of the plurality of patients to respective chronic diseases. The method includes determining, for the plurality of patients, health risk scores for the respective chronic diseases by applying disease models for the respective chronic diseases to the clinical data.
