A method and systems for determining an early warning score for a health status of a patient are provided. An example method includes acquiring, during a predetermined time period via sensors integrated into a wearable device worn on a wrist of the patient, initial values of medical parameters of patient. The medical parameters include a respiratory rate, oxygen saturation, temperature, blood pressure, and pulse rate, and level of consciousness. The method includes determining, based on the initial values, normal values of the medical parameters. The method includes acquiring, via the sensors and at a pre-determined frequency, further values of the medical parameters. The method includes determining, based on deviations of the further values from the normal values, individual scores for the medical parameters. The method includes calculating, based on the individual scores, a general score. The method includes determining, based on the general score, the health status of the patient.
