DISEASE PROGRESSION HAZARD RATIO BASED ON EHR DATABASE

Abstract:

In an approach for identifying disease progression hazard ratios for given disease against diseases from an EHR database to determine top comorbidities to the given disease, a processor receives raw EHR data. A processor identifies, from the raw EHR data, a set of diseases and associated diagnosis information for each disease of the set of diseases. A processor calculates a hazard ratio for each disease pair of a set of disease pairs producing a set of hazard ratios, wherein the set of disease pairs comprises a given disease paired with each disease of the set of diseases. A processor ranks the set of hazard ratios for the given disease. A processor selects a pre-defined number of top comorbidities of the set of hazard ratios for the given disease based on the ranking. A processor outputs the pre-defined number of top comorbidities for the given disease.
