Abstract: A data processing system to determine a risk factor of an impending transfer to the emergency department of an individual. The system includes a database which stores a plurality of status records for each person of a set of people. Each status record is dated and includes a list of monitoring indicators. Each indicator has a value chosen from a list of two predetermined values according to the status of the corresponding person. The system also a microprocessor to determine the risk factor by analyzing a plurality of status records of the individual, filled out according to the status of the individual, using a machine learning algorithm. The parameters of the algorithm being generated beforehand. A data processing method is further provided to determine a risk factor for an impending transfer of the individual to the emergency department.
