1. A computerized method for providing multidimensional medical decision support, the method comprising: defining and storing, in a computer database, a set of input variables for a patient being evaluated, each input variable associated to a corresponding relevant clinical dimension for establishing a diagnosis for a patient, the relevant clinical dimensions are a chief complaint, a history of present illness, a past medical history, a past surgical history, a medication, an allergy, a vital sign, a physical exam (PE) and a diagnostic test; defining and storing, in the computer database, interdimensional relationships between and among the relevant clinical dimensions so as to define at least drug-disease, and drug-allergy testing interaction relationships; entering, into the computer, particular values for the input variables in the course of examining a patient; selecting at least a portion of the set of input variables from the group of relevant clinical dimensions consisting of a current complaint dimension, a medical history dimension, a surgical history dimension, a current medications dimension, a laboratory results dimension, a social history dimension, and a family history dimension; the computer automatically identifying particular ones of the interaction relationships specific to the particular patient being examined, wherein the particular ones of the interaction relationships are identified to a physician during the course of the examination; displaying the particular ones of the interaction relationships specific to the particular patient during the examination of the patient by the physician; and the computer automatically inferences in real time and presents treatment choices that are simultaneously adjusted, in a patient and context-specific fashion, for interaction safety, therapeutic efficacy, economic factors, and correct dosing.
