Disease simulation system and method
A system and method for predicting the effect of patient self-care actions on a disease control parameter. A future disease control parameter value X(t j ) at time t j is determined from a prior disease control parameter value X(t i ) at time t i based on an optimal control parameter value R(t j ) at time t j , the difference between the prior disease control parameter value X(t i ) and an optimal control parameter value R(t i ) at time t i , and a set of differentials between patient self-care parameters having patient self-care values S M (t i ) at time t i and optimal self-care parameters having optimal self-care values O M (t i ) at time t i . The differentials are multiplied by corresponding scaling factors K M . The system includes an input device for entering the patient self-care values S M (t i ). A memory stores the optimal control parameter values R(t i ) and R(t j ), the prior disease control parameter value X(t i ), the optimal self-care values O M (t i ), and the scaling factors K M . A processor in communication with the input device and memory calculates the future disease control parameter value X(t j ). A display is connected to the processor to display the future disease control parameter value X(t j ) to a patient.
