ystem) An application that supports a physician's diagnosis and treatment. A CDSS that uses a knowledge base of symptoms helps doctors diagnose the patient, while a drug knowledge base helps them prescribe medicines that do not conflict with other drugs the patient is taking. Instead of a knowledge base, a CDSS may use algorithms that evaluate random solutions in order to find the one that seems best.

However, the Health IT for Economic and Clinical Health Act (HiTECH) requires that healthcare providers implement a DSS rule for ordering diagnostic tests by 2015. See healthcare IT
