Clinical Decision Support
CDS; Decision support
Clinical Decision Support systems are computer systems which assist humans in making optimal clinical decisions. While clinical decision support systems are most often designed for clinicians, they can also be developed to assist patients or caregivers. Common examples of clinical decision support systems include drug-drug interaction checks, dose range checking for medication and preventive care reminders.
The first clinical decision support system was described in 1959 by Robert Ledley and Lee Lusted  in their paper “Reasoning foundations of medical diagnosis; symbolic logic, probability, and value theory aid our understanding of how physicians reason.” Ledley and Lusted described an analog computer used to sort cards containing a diagnosis and a series of punches which represented symptoms. By selecting the cards which matched the symptoms present in a given case a clinician could develop a possible set of diagnosis.
