Abbreviations are used more and more in physician common parlance and it seems they are on the way to becoming a new jargon. However, identical abbreviations may have different meanings, especially in different medical specialties. Moreover, many physicians do not know the meaning of specific abbreviations or are attributing the wrong meaning to the abbreviation. This will lead to misunderstanding and therefore danger to the patient. The authors are calling for a stop on the use of spoken abbreviations and for minimising the use of abbreviations in clinical notes and medical prescriptions
