Active monitoring and early warning system and method for drug-induced diseases

The invention provides a drug-induced disease active monitoring and early warning system, which comprises a first acquisition module used for acquiring the medicine taking moment of a patient; the second acquisition module is used for acquiring multiple pieces of first feature information of the patient in a first preset time period before the medicine taking moment and acquiring second feature information, corresponding to the first feature information, of the patient in a second preset time period after the medicine taking moment at a preset frequency; the calculation module is used for calculating the change rate and the change amplitude of the feature information according to the first feature information and the second feature information; and the monitoring and early warning module is used for generating an early warning signal when the change rate is greater than a first preset rate threshold value and/or the change amplitude is greater than a first preset amplitude threshold value.
