This class represents the results of a Drug Use Evaluation (DUE) or a Drug Utilization Review (DUR). Both phrases refer to an analysis of the use of the prescribed drug in the context of the patient’s overall drug and substance exposures, and disease state which would potentially cause that medication to be contra-indicated. This process may include the evaluating the prescribed drug against the patient’s allergies or intolerances. The phrases are distinct because one (the DUE) generally occurs during the ordering/dispense process, while the other (DUR) generally is performed after the drug has been dispensed. Note that some institutions use these phrases interchangeably. While this process is traditionally called DUE or DUR, this process often includes all kinds of Medical Products (including Medical Foods, etc.). Hence some institutions use the term Medication or Medical Product instead of the use of Drug.
