Abstract: The new healthcare system of the present invention uses Medical Advance-Practice Standard (“MAPS”) decision-making model for providing better patient care. MAPS model embodies the medical practice standard established by the best major medical hospitals and research centers. While providing the capability for fast, accurate, monitoring of the integrity of the physician-patient transactions, using computational science and simulation modeling, MAPS assists medical practitioners to diagnose and treat patients, and provides the basis for scientifically defensible and broad-based financial medical decisions.
