Medical information system and method to obtain reasoning for therapeutic events

An interactive medical information system query process is used to learn the reasons that a medical practitioner initiates a therapeutic event for a patient. The practitioner's reasons are expressed in responses to context specific queries generated by the system. A database maintains an electonically searchable library of drug prescriptions with dose characteristics. The prescription database is used to generate a prescription based upon patient profile characteristics. The system operator selects a generated prescription. The medical information system tracks prescription samples, narrative records, and notes and conducts flash surveys of participating practitioners.
