Disease management system and method including correlation assessment

Abstract

One aspect of the invention is directed to a system and method for allowing a patient to access an automated process for managing a specified health problem called a disease. The system performs disease management in a fully automated manner, using periodic interactive dialogs with the patient to obtain health state measurements from the patient, to evaluate and assess the progress of the patient's disease, to review and adjust therapy to optimal levels, and to give the patient medical advice for administering treatment and handling symptom flare-ups and acute episodes of the disease. The medical records are updated, the progression of the disease is stored and tracked, and the patient's preferences for treatment are stored and then used to offer medical advice based on the current state of the disease. Subjective and objective health measurements are used to determine a metric, which can be used to adjust patient therapy.

         14 . The system of    claim 10   , wherein the metric is indicative of whether the subjective health measurement is reliable.  
     
     
         15 . The system of    claim 10   , wherein the disease management module is additionally configured to adjust a therapy for the particular patient based on the metric.  
     
     
         16 . The system of    claim 10   , wherein the subjective health measurement comprises health data perceived or felt by the particular patient.  
     
     
         17 . The system of    claim 10   , wherein the objective health measurement includes health data measured by the particular patient.  
     
     
         18 . The system of    claim 17   , additionally comprising a medical instrument configured to measure the health data.
