Medicalese Glossary

Many professions use jargon, a collection of specialized or technical language unique to the field that may not be understood by people outside of that field. The use of slang, or informal words and expressions, as well as abbreviations is also common. Medicine is certainly no exception. International medical graduates (IMGs) who enter U.S. residency or fellowship positions will find that there are many terms that are particular to U.S. medicine. Many of these terms, which we call “Medicalese,” may be new and initially confusing to IMGs, even those who come from countries where the language of instruction is English and who speak and comprehend English quite well. U.S. “Medicalese” differs even from “Medicalese” in other English-speaking countries, such as the United Kingdom.

ECFMG’s Acculturation Program has developed this glossary of “Medicalese“ to help orient newly arriving IMGs to some of the terminology commonly used by doctors, nurses, and other medical staff in U.S. hospitals and clinics. It is our hope that this glossary will facilitate understanding of these terms when they are used by others.

Note that the table below includes several abbreviations or acronyms. These are included because they are often spoken as such. However, it may be better, especially for those new to “Medicalese,” to say the complete term in order to avoid any confusion.

It is important to understand that some of the slang, abbreviations, and jargon commonly used within medical practice might sound insensitive to patients or their families. These terms, therefore, should not be used in situations where they may be overheard. Unfortunately, some misguided medical staff may also use terms that are disrespectful or belittling to patients. Such inappropriate terms have no place whatsoever in the professional practice of medicine and are not included on this list.

As with all resources on the ECFMG Acculturation website, the “Medicalese,” glossary is a work in progress. If you have suggestions for additional words, phrases, or abbreviations to be added to this list, please submit them for consideration to acculturation@ecfmg.org.
