One of the main targets of criticism from the National Health System (NHS) is the diagnostic appropriateness: it is estimated that it causes a cost increasement of 30 %.
Furthermore, an inappropriate exams request leads to negative consequences to the patient, such as exceeded radiation exposure, treatment time wasted during pointless examinations and extends the waiting lists.
To address this problem, the American College of Radiology (ACR) and the European Society of Radiology (ESR) have collaborated for creating a Clinical Decision Support system (CDS) called iGuide.
The iGuide is a software which allows reasonable prescription of imaging diagnostic exams according to the guidelines elaborated by the ACR and the ESR.
The software, considering the clinical context, can provide the level of appropriateness (Evidence-Based) of a diagnostic procedure, an estimate of the radiation exposure and also of the cost.
