Preface to the 6th Edition

This sixth edition of Jablonski’s Dictionary of Medical Acronyms & Abbreviations is the first tobe published without the tireless work of Stanley Jablonski, who passed away just before thepublication of the fifth edition. The book has been extremely well received over the years, and theauthor’s enthusiasm and love of medical vocabulary in all its forms, even maddeningly obscureabbreviations, are evident in its pages. The task of maintaining this volume now falls to the staff of the Dorland’s dictionaries, who are well aware of the tradition of excellence that they haveinherited.

Although responsibility for maintaining the text has changed, the book itself remains thefamiliar, convenient little volume that has served users well for two decades. The book retains itsformat of boldface abbreviations followed by run-in meanings, a device that enables it toencompass as many entries as larger, heavier books in an easy-to-handle size. The list of symbols,which has been expanded for this edition, is in its usual place at the front of the book. The listingsfor organizations have been updated: new ones have been added; name changes have beenincorporated; outdated names have been cross-referenced to new ones (or dropped, whenthoroughly obsolete, to make room for new material). Abbreviations and acronyms are includedin a single alphabetically arranged section (no need to flip through multiple sections) and severalthousand new entries have been added. The CD-ROM that accompanies this book has been

improved from that of the previousedition —it is searchable for both abbreviations and meanings,which will greatly increase its usefulness.

As has been noted by many, the convenience of using acronyms and abbreviations can beoutweighed by the danger in doing so. In some cases, ambiguity in interpretation can lead tosituations in which patient safety may be compromised. For this reason, the Joint Commission(JCAHO) has created a list of abbreviations that are considered dangerous and should not be usedin a health care setting. The abbreviations included in this edition have been compared with theJCAHO ‘‘Do not use’’ list, and those that occur on this list are so identified.

The new editors of Jablonski’s Dictionary of Medical Acronyms & Abbreviations wouldlike to express our admiration for the work that has been handed down to us and also ourdetermination to maintain the book’s high standards going forward. Because new acronyms andabbreviations are constantly being coined, this volume can never really be complete. We inviteyou to submit your suggestions for the next edition. You can do this by going to the Internet sitehttp://www.dorlands.com and clicking on ‘‘Suggest a Word. ’’ Just tell us that it is for Jablonski .You can be sure that your contributions will be much appreciated.

Acknowledgments

The publisher would like to thank Christopher Peterson, MD, PhD, of Rio de Janeiro, Brazil, forhis continuing interest in the book and for supplying several hundred new entries for this sixth

edition. The work of Tsung O. Cheng, MD, of Washington, DC, was extremely useful forverifying acronyms for cardiology trials and is gratefully acknowledged: Cheng TO: Acronymsof Clinical Trials in Cardiology —1998. American Heart Journal 137:726–765, 1999.

Preface to First Edition

Acronyms and abbreviations are used extensively in medicine, science and technology for goodreason —they are more essential in such fields. It would be difficult to imagine how one couldwrite down chemical and mathematical formulas and equations without using abbreviations orsymbols. In medicine, they are used as a convenient shorthand in writing medical records,instructions, and prescriptions, and as space-saving devices in printed literature. It is easier andmore economical to write down the acronyms HETE and RAAS than their full names12- L-hydroxy-5,8,10,14-eicosatetraenoic acid and renin-angiotensin-aldosterone system, respec-tively.

The main reason for abbreviations is said to be economy. Some actually save space in print,such as acronyms for the names of institutions and organizational units, as well as beingconvenient to use. Many are used for other reasons, as for instance, when trying to be delicate, wemay euphemistically refer to bowel movement as BM, an unprincipled individual as SOB, andbody odor as BO. Also, it is sometimes difficult to fathom the reasoning of bureaucratic acronymmakers, who have created some tongue-twisting monstrosities, such as ADCOMSUBORD-COMPHIBSPAC (for Administrative Command, Amphibious Forces, Pacific Fleet, SubordinateCommand).

Abbreviations and acronyms used in medicine can be grouped into two broad categories. Thefirst consists of official abbreviations and symbols used in chemistry, mathematics, and othersciences, and those designating weights and measures, whose exact form, capitalization, andpunctuation have been determined by official governing bodies. In this category, they mean onlyone thing (e.g., kg is the symbol for kilogram and Hz for hertz), and their form, capitalization, andpunctuation have been established by the International System of Units (Syste `me Internationald’Unité s). Abbreviations in the second group, on the other hand, may appear in a variety of forms,the same abbreviation having a different number of letters, sometimes capitalized, at other timesnot, with or without punctuation. Moreover, they may also have numerous meanings. Theabbreviation AP may mean alkaline phosphatase, acid phosphatase, action potential, anginapectoris, and many other things.

Editors of individual scientific publications make an effort to standardize the form of abbreviations and symbols in their journals and books, but they generally vary from onepublication to another.

This dictionary lists acronyms and abbreviations occurring with a reasonable frequency in themedical literature that were identified by a systematic scanning of collections of books andperiodicals at the National Library of Medicine. Except as they take the form of Greek letters,pure geometric symbols are not included. Although we have attempted to be as inclusive aspossible, a book such as this one can never be complete, in spite of the most diligent effort, and itis expected that some abbreviations and acronyms may have escaped detection and others mayhave been introduced since completion of the manuscript.
