Computer based risk level monitor and patient compliance method and system

The risk monitor, as a computer-based method, program or system, monitors medical compliance by a plurality of patients having a corresponding plurality of medical compliance plans. The plans for each patient are displayed and the system accepts input from the patient indicative and / or heathcare providers of the patient's compliance with the plan. The system then assesses or analyzes the input and assigns a corresponding risk value based upon a range of risk values for various degrees of compliance. In addition, the patient's lifestyle inputs can be added to determine the risk value. The assessment continues for a plurality of patients thereby providing an indication of the risk value (a total risk value) for a patient, doctor, group of healthcare providers, a clinic or a hospital. By implementing various communication episodes (telephone calls, e-mails, letters), the system seeks to reduce the risk value for a particular patient and for the plurality of patients by altering the communication episodes and monitoring the resulting risk values both individually and as a group.
