摘要： The present invention discloses methods, computer program and system to overcome the limitation of the current clinical practice. This is achieved by using information technology and the vast amount of epidemiological data available to create algorithms that calculate the risk or severity profile of an individual with any given disease. The individual profile presents the current condition and/or position of the individual in comparison with the mean base curve of the total population and in accordance with upper and lower risk limits. The individual profile is then fitted with its optimal use of healthcare resources, such as medication, surgery, laser treatment, surveillance and follow-up, to optimize and individualize the health outcome of this individual, and at the same time optimize and individualize the allocation of healthcare resources within the system.
