Abstract

The data generation device includes an acquisition unit, a virtual patient data generation unit, a time-series data generation unit, and an output unit. The acquisition unit acquires data regarding a treatment of a patient. The virtual patient data generation unit generates data regarding treatment in each stage of the medical condition of the virtual patient based on the data regarding treatment of the patient. The time-series data generation unit generates time-series data regarding the medical condition of the virtual patient from the generated data regarding treatment of the virtual patient. The output unit outputs the generated time-series data regarding the medical condition of the virtual patient. With such a configuration, the data generation device can support decision-making regarding the patient’s medical condition.
