List of medical abbreviations
Abbreviations are used very frequently in medicine, despite being widely discouraged by the Institute of Safe Medicine Practices and other organizations concerned about patient safety.[1] Abbreviations are especially discouraged when healthcare providers are communicating with patients and when there is a possibility of confusion between similar abbreviations.[1] Some facilities maintain a list of acceptable abbreviations.[2] Abbreviations are sometimes specific to a facility,[2] which means that newer staff may be unfamiliar with them; this becomes a potential source of preventable medical errors.[1]
The Joint Commission and other organizations maintain lists of certain medical abbreviations that should be avoided to prevent mistakes,[2] according to best practices (and in some cases regulatory requirements); these are flagged in the list of abbreviations used in medical prescriptions.
Orthographic styling
[edit]Periods (stops)
[edit]Periods (stops) are often used in styling abbreviations. Prevalent practice in medicine today is often to forgo them as unnecessary.
- Example:
- Less common: The diagnosis was C.O.P.D.
[chronic obstructive pulmonary disease] - More common: The diagnosis was COPD [3]
- Less common: The diagnosis was C.O.P.D.
Plurals
[edit]The prevalent way to represent plurals for medical acronyms and initialisms is simply to affix a lowercase s (no apostrophe).
- Example: one OCP, two OCPs [oral contraceptive pills]. [4]
Possessives
[edit]Possessive forms are not often needed, but can be formed using apostrophe + s. Often the writer can also recast the sentence to avoid it.
- Example:
- BP's effect on risk of MI is multifaceted.
- The effect of BP on MI risk is multifaceted.
Arrows
[edit]Arrows may be used to indicate numerous conditions including elevation (↑), diminution (↓), and causation (→, ←).[5]
Pronunciation
[edit]Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior"). Abbreviations of weights and measures are pronounced using the expansion of the unit (mg = "milligram") and chemical symbols using the chemical expansion (NaCl = "sodium chloride").
Some initialisms deriving from Latin may be pronounced either as letters (qid = "cue eye dee") or using the English expansion (qid = "four times a day").[citation needed]

Notation conventions
- This series of lists omits periods from acronyms and initialisms.
- It uses periods for certain abbreviations that traditionally often have them (mostly older Latin/Neo-Latin abbreviations). For example, both bid and b.i.d. may be found in the list.
- It generally uses the singular form of an abbreviation (not the plural) as the headword.
- This list uses significant capitalization for headwords (the abbreviations) and their expansions. [6]
