The doctors go online and get the patient's data (medical history, drugallergies, etc), which happens to be stored on the computer of a clinic on the other side of the world.
Some employ clever strategies such as memorizing symptoms to get a certain prescription or telling their doctors they have allergies to particular medication to get a stronger drug.
Andrew Husband, principle lecturer in pharmacy at the University of Sunderland and lead on the Gateshead study said allergies were a significant cause of avoidable adverse drug reactions among hospital in-patients each year.
Some 30, 000 Americans go to the emergency room each year because of severe food allergies, said Dr. Stefano Luccioli of the Food and Drug Administration's Office of Food Additive Safety.
