CDSS（Clinical Decision Support System）,Clinical decision support system,Generally, it refers to a computer system that can support clinical decision-making,This system makes full use of available、Appropriate computer technology,For semi-structured or unstructured medical problems,Improve and improve decision-making efficiency through human-computer interaction.Research on CDSS originated in the late 1950s,By medical experts through reasoning engine,Store the professional knowledge and clinical experience in the knowledge base,Using logical reasoning and pattern matching,Help users to make diagnosis inference,It's an expert system.Mid-1970s,The birth of the first CDSS system in the world,According to the input inspection information, the system can,Automatic identification of 51 pathogens,Correct use of 23 antibiotics,It can help doctors diagnose and treat bacterial infectious diseases,Best prescription for patients.Since then,CDSS systems with various functions and features appear one after another,The focus of research on CDSS has also shifted from simulation expert thinking to how to make the system better adapt to the actual diagnosis and treatment process of patients through various computer technologies,Assist clinician to make diagnosis decision.

With the development of artificial intelligence technology and its application in medical field,Clinical decision support system based on artificial intelligence appeared and gradually landed in major hospitals and basic medical institutions,Assist doctors in clinical decision making,Widely concerned by the industry.Clinical decision-making of undergraduate requires clinicians to have multi-disciplinary、Multi domain medical knowledge.in addition,CDSS can help the grassroots to establish homogeneity、Standardized medical pat,Help grassroots doctors avoid misdiagnosis and missed diagnosis of common diseases,At the same time, help them to make scientific referrals,Help to improve the quality of basic medical services,Better promote the implementation of hierarchical diagnosis and treatment policy,The current situation of alleviating the uneven distribution of medical resources.
