Effective medical decision support systems (MDSS) are a constantly evolving knowledge base at the crossroads of biomedical science, medical institutions, doctors, and other professionals .
It is obvious that great care must be used while choosing the proper drugs, as not all will be equally helpful for a certain person with a unique genetic code and physical attributes. Clinical cases, suggestions, and treatment algorithms are all improving, thus the knowledge base should be updated. Furthermore, a definite trend toward individualized medicine is emerging, which will be aided by intelligent information technologies. In this example, the knowledge base with MDSS is a specific software product that uses semantic and cloud technologies, rather than a set of rules.
