Yale School of Medicine Writing Style Guide

The Yale School of Medicine Writing Style Guide generally follows the journalistic style manual published by The Associated Press Stylebook. It addresses issues that may be encountered by writers for the Yale Medicine clinical practice web site, whose audiences include patients and referring physicians; and those writing for Yale Medicine Magazine and Medicine@Yale newsletter.

This style guide is organized like a dictionary, for ease of use. Entries are boldfaced, and examples are set in italics.

Some guidelines include style, usage, spelling and references from external sources.

In addition to The Associated Press Stylebook, writers and editors should consult Webster’s New World College Dictionary or Merriam Webster online with questions on such matters as spelling and hyphenation. They should also be familiar with the Disability Language Style Guide published by the National Center on Disability and Journalism.


A

abbreviations

  • Avoid where possible, especially in the case of well-known abbreviations, e.g. operating room (not OR), emergency room (not ER)
  • Do not use abbreviations or acronyms the lay reader would not recognize
  • If an abbreviation is used more than once in a story, introduce it in parentheses at first use

acronyms

  • Whenever possible, avoid acronyms as a way to describe Yale organizations. On second references, it’s better to call our entities the hospital, the cancer center, etc.
  • If a writer must use an acronym, use it only after a proper name has been fully spelled out with the acronym in parentheses on first reference, e.g. Northeast Medical Group (NEMG). Do capitalize for a proper name: National Institutes of Health (NIH)
  • Always spell out Yale Medicine; do not use YM or any other acronym to describe the clinical practice. Do not capitalize the words from which an acronym is derived, e.g. intensive care unit, ICU; computed tomography, CT; magnetic resonance imaging, MRI; chief executive officer, CEO.

academic degrees

See credentials

academic departments

Capitalize the formal name: Department of Dermatology, Section of Cardiology, or Yale Medicine Dermatology, Yale Medicine Cardiology. Lowercase the informal, shortened name: dermatology department, cardiology section.

addict

Refer to someone who harmfully uses drugs or alcohol as “a person with a substance use disorder” or “a person with an alcohol addiction.” Use “recovering” or “in recovery from” to refer to someone trying to overcome active addiction or who is in long-term recovery. Avoid terms like “junkie” and “user.”

addresses

  • Abbreviate Ave., Blvd. and St. only with a numbered address (267 Grant St.). Spell out all others (Drive, Road, Terrace, Lane, etc.)
  • Capitalize when used with a number
  • Lowercase and spell out when using more than one street name (Cedar and York streets)

advanced practice registered nurse

Spell out on first use; use APRN for subsequent references. Do not use nurse practitioner or NP.

African American

Do not hyphenate when used as a noun or an adjective. Both “African American” and “Black” are acceptable for an American Black person of African American descent, but they are not necessarily interchangeable. When in doubt, check AP Style entries on “African American” and on “nationalities and race.” See “Black” for further guidance on writing about race.

ages

Use AP style. Always use numerals, e.g. a 5-year-old boy; John Smith was 30; a man in his 20s; a 2-hour-old infant. Only hyphenate when the age is used as an adjective, e.g. a 5-year-old boy.

AIDS

Acceptable in all references for acquired immune deficiency syndrome. AIDS is caused by human immunodeficiency virus, or HIV. (HIV virus is redundant.)

alphabetical order

Wherever possible, use alpha order when creating lists, such as lists of departments, names of chairs, etc.

ampersand

  • Do not use as a substitute for the word “and”
  • Use when it is the official part of a name, e.g. U.S. News & World Report, and/or in select digital instances in which character counts are limited (i.e., on Twitter or other social media platforms)
  • Always use “&” instead of the word “and” when referring to Yale Medicine and YSM departments, sections and programs, i.e.: Yale Medicine Orthopaedics & Rehabilitation; Yale Medicine General Surgery, Trauma & Surgical Critical Care; Yale Medicine Speech & Swallow Program, Department of Cellular & Molecular Physiology

a.m., p.m.

Lowercase, with periods.

amount, number

Use amount for a continuous substance, number for discrete objects: a large amount of evidence, a large number of studies.

anesthesia

Not anaesthesia.

appointed

Do not use with “as”: Linda Mayes, MD, was appointed (not appointed as) chair of the Yale Child Study Center.

apposition

Use commas around a word, phrase or clause used in apposition if it is not essential to the meaning of the sentence. Examples: John Doe and his wife, Mary, attended the reunion. But: John Doe and his daughter Julie attended the reunion; his wife, Mary, and Rebecca, his other daughter, weren’t able to attend. (In the second example, no commas are used in the first clause because Julie is not John’s only daughter.) Note that we make an exception to this rule in the Alumni Reunion Reports when there is no possessive (his, her, etc.) preceding wife, husband, children, etc.: John Doe and wife Mary.

army

Capitalize when referring to U.S. forces: the Army, the U.S. Army, the French army.

arteriosclerosis

This is the general term for the abnormal thickening, and loss of elasticity, of artery walls. Note that atherosclerosis is a form of arteriosclerosis. See atherosclerosis.

atherosclerosis

Note spelling (ath-, not arth-). A form of arteriosclerosis.

B

Biomedicine

Black

When referring to Black people, use initial cap for “Black” (“white” people should be lower case).

board of trustees, the board, the trustees, a trustee

Capitalize only when the reference is a formal noun. Lowercase “board of trustees” in subsequent reference; lowercase the board, the trustees, a trustee.

board-certified

Hyphenate in all instances. When editing concepts, keep “board-certified” if it’s already there, but don’t add it.

Boyer

Boyer Center for Molecular Medicine, 295 Congress Ave., next to the Hope Building and the corner of Congress and Cedar. The building was dedicated in 1991, designed by Cesar Pelli and Associates, and named for Dr. and Mrs. Herbert Boyer of Mill Valley, Calif.

brackets

Use to set off a clarifying item inserted in a direct quote, e.g. “She said, “I’ll be back at 7 [p.m.] to get my things.”

bulleted lists

  • The use of bullets is encouraged when they can be used to help make information more digestible.
  • Punctuation in bullets should only be used when a bullet contains a complete sentence or multiple sentences.
  • When a bulleted list is made up of single items, alphabetize them.

C

Campus

  • Capitalize the word Campus in both Saint Raphael Campus and York Street Campus. Lowercase when using as plural, e.g., “Both campuses,” or “Saint Raphael and York Street campuses
  • Capitalize proper names, e.g. “Lawrence + Memorial Hospital” or “Yale New Haven Health” or “Bridgeport Delivery Network,” but lowercase “hospital,” “system” or “delivery network” in subsequent references.

cancer staging

  • Stages range from 0-IV, with 0 being localized (best) and IV being distant spread (worst).
  • Capitalize Stage and use Roman numerals.

capitalization

  • Capitalize proper names, e.g. Yale Medicine, Yale School of Medicine, but lowercase system and school in subsequent references.
  • Capitalize departments, programs, committees and centers; e.g. Department of Psychiatry, Yale Cancer Center, but not psychiatry department or cancer center.
  • Do not capitalize job titles unless the title precedes the person’s name; e.g. Dean Nancy J. Brown, MD; Nancy J. Brown, dean.
  • Do capitalize job titles if they are in list form in the middle of an email message or on a poster.
  • Capitalize all acronyms, e.g. YM, YSM, YNHHS, and do not use periods.
  • Capitalize the principal words in the names of books, movies, plays, radio or TV programs, etc.
  • Lowercase university unless using the proper name: Yale University.
  • Capitalize Endowed Chair when used with the endowed chair’s name, whether it precedes or follows the holder’s name; e.g. Donald Smith, The Kate and Harvey Cushing Professor of Neurosurgery or The Kate and Harvey Cushing Professor of Neurosurgery Donald Smith. (“The” with a capital “T” is sometimes part of the official name of the endowed chair title. When in doubt, writers should check this.)

captions

  • Include a description of what is happening in the photo. Example: A camera records Shanta Kapadia’s dissection while Charles Duncan (left) and William Stewart observe on a monitor. Video instruction is a key part of the flipped classroom.
  • Identify everyone in each photo (first and last names).
  • In general, write captions in present tense, although it can depend on the situation.
  • Directionally, start identification at the left side of the photo. Use (l-r) whenever possible. Use such terms as top, bottom, left, right, above, below or clockwise from left when necessary.
  • With two people, the person on the left is generally indicated, e.g. “Bill Jones (left) and Bob Smith,” unless clear, e.g. “Bill Jones and Mary Smith.”
  • Use semicolons if the caption identifies more than two people with titles. Mary Smith, RN; and Jack Jones, MD.
  • Do not use middle initials in photo captions, or academic or other titles except for degrees (MD, PhD, RN, etc.) However, these can be OK in more descriptive captions. Some of this information may be used in more descriptive captions.
  • When writing a caption for a photo, the same caption will be adopted for people viewing the story/photo on smartphones and on tablets, so brevity will be a critical element. Remember that if the photo caption is two lines on PC, it might be four lines on a tablet and six lines on a smartphone.

caregiver

This term refers to any member of a Yale Medicine care team, regardless of education or title. That includes doctors, nurses and technicians, as well as administrative and clerical staff, as they all affect the care experience.

Centers for Disease Control and Prevention

Abbreviation: CDC. An agency of the federal Department of Health and Human Services, located in Atlanta, Ga. The name was changed from the Centers for Disease Control in 1992.

Center for Musculoskeletal Care

The center is currently open at the Long Ridge Medical Center in Stamford, and plans are being made for a New Haven location.

chair

  • The head of an academic department holds the title of chair (not chairman, chairwoman or chairperson)
  • Capitalize endowed-chair titles, regardless of whether the title precedes or follows the holder’s name: Spencer Tracy, The Kate and Harvey Cushing Professor of Neurosurgery. (An endowed chair is a professorship that has been funded through philanthropy. The current cost of endowing a professorship at Yale is $2.5 million; the proceeds of this fund are intended to cover the faculty members’ salary and expenses.)

chair, chief

  • An individual is chair of a department at YSM and chief of the same department at YNHH. Lowercase these words. Use both if space permits; otherwise use the university title. (Note that the title of chief is also used at YSM for faculty who head up a section, such as Internal Medicine’s Section of Allergy and Immunology.)

clinical trials

  • Phases run from preclinical to Phase 0-V
  • Capitalize Phase and use Roman numerals

Clinician Educator-Scholar track

Hyphen only between "educator" and "scholar." No hyphen for abbreviation (CES track)

co

Per AP (includes some exceptions to WNW): “Retain the hyphen when forming nouns, adjectives and verbs that indicate occupation or status.” Examples: co-chair, co-authored, co-editor. Do not use hyphen in other instances: coeducation, cooperate, coordinate. These last two examples—cooperate and coordinate (and related words)—are exceptions to rule no. 1 in the prefixes entry regarding use of hyphen.

co-sign

Use a hyphen

commas

Do use a comma before a conjunction in a compound sentence, e.g. The doctor’s office was sparsely furnished, and it was located on the basement level

We will use the serial comma, or the comma that would appear at the end of a simple series, before the concluding conjunction. e.g. red, white, and blue.

comprise

Use comprise when referring to all components of something: The United States comprises 50 states. Use include when only some components are mentioned: Saturday’s reunion activities include brunch in the Commons. See AP for more detail.

copyright symbol

Use © only if necessary and then only at the first mention, as superscript.

Dickey, MD, chief; Judy Gorelick, MD, attending physician; and Kenneth Vives, MD, associate physician Degrees: When writing about an appointment, AP style is to spell out, lowercase and use apostrophe for degrees, e.g. “master’s degree in public health” or “associate’s degree in nursing.” For Yale Medicine, BA, MS, MD, etc. are also acceptable
*** Exception for Yale Medicine Magazine and Medicine@Yale: Both publications use years after degrees for alumni: MD ’70, PhD ’01, etc. The magazine also uses years after HS, for residencies; and FW for fellowships. M@Y does not use years after degrees unless it is somehow relevant to the story.

CT scan

Not CAT scan.

Cushing/Whitney Medical Library

Though the full name is Harvey Cushing/John Hay Whitney Medical Library, Cushing/Whitney Medical Library is acceptable on first reference.

D

dashes

  • Use em dashes – (the length of two hyphens) to denote an abrupt change in thought or to set off a series within a phrase. We do not use a space on either side to set off an em dash. (To create an em dash on the PC, hold down the ALT key and type 0151 on the numeric keypad. Only the numbers on the right hand keypad do this. On the Mac, press Shift-Option and the minus key.)
  • Use en dashes (a little longer than the length of one hyphen) to separate date and page ranges. (To create an en dash on a PC, type “Ctrl” and the minus sign on the numeric keypad, or “Alt” and then enter in “0150.” For a Mac, hold down “Option” and “-”)

data

Plural; use with plural verb: The data were convincing.

dates, months, days of the week

  • When only the month is used, do not use a comma before the year, e.g. January 2007
  • When a specific date is used, abbreviate only these months: Jan., Feb., Aug., Sept., Oct., Nov. and Dec. All other months are spelled out, e.g. Feb. 11, 2013 or March 14, 2013
  • Include the day of the week with the date for upcoming events and use cardinal, not ordinal numbers, e.g. Tuesday, March 14, not Tuesday, March 14th
  • Do not abbreviate days of the week unless in tabular format; then use Sun., Mon., etc.
  • Spell out in full in formal invitations or when appropriate
  • Use en dashes to separate ranges, e.g. Jan.–Dec. or Mon.–Fri. To create an en dash on a PC, type “Ctrl” and the minus sign on the numeric keypad, or “Alt” and then enter in “0150.” For a Mac, hold down “Option” and “-”

disease names

Use ’s with diseases bearing a person’s name: Alzheimer’s disease, Down’s syndrome, Tourette’s syndrome. Note the lowercase s in syndrome. Say a patient has Alzheimer’s disease, or a patient with Down’s syndrome. Never say a patient is “suffering from” or “is a victim of” a disease.

disabled

NCDJ Recommendation: When describing an individual, do not reference his or her disability unless it is clearly pertinent to the story. If it is pertinent, it is best to use language that refers to the person first and the disability second. For example: “The writer, who has a disability” as opposed to “the disabled writer.” When possible, refer to a person’s specific condition.

disk

Use disk (not disc) for medical references such as a slipped disk

doctor

Use the word physician or doctor as a noun instead of MD, e.g. “The doctor was compassionate.” (not “The MD was compassionate.”)

use MD on first reference, Dr. later in text. No periods in Yale Medicine copy. This is an exception to AP Style

drug names

  • Use the generic name unless there is a reason to use the brand name.
  • Use lowercase for nonproprietary (generic) drug names: disulfiram. Capitalize proprietary (brand) names: Antabuse. Use the following websites to check drug names: www.rxmed.com, www.rxlist.com.

E

e.g.

May be used in place of “for example” with a comma before but not after.

em dashes

Do not use spaces surrounding em dashes. For example: “Generally, using the em—dash makes the writing style less formal—as if you were writing to a friend."

email

No hyphen. Avoid breaking up email addresses on two lines; if unavoidable, break at the @ symbol.

e-newsletter

Use hyphen

etc.

Use commas before but not after; e.g. Rats, mice and men, etc. were the topics.

ellipsis

When an ellipsis is used to indicate deletion of one or more words, use three periods, with a space before the first and after the last period. For example: “Due to numerous factors … this was a complicated procedure,” said Dr. Smith. (Treat the ellipsis as you would a three-letter word)

Epic

Capitalize only the E, not the other letters. Epic is the brand name of the electronic medical record used by Yale Medicine and YNHHS.

expert

Use with on (not in): An expert on the psychopharmacology of schizophrenia. Can also say authority on. See specialist and prepositions.

F

facts

Use facts from .gov, AMA and other trusted sources. Concept editors and writers: Give the source name, but not the name of the report or date. Call it recent data.

fellow

Note lowercase f (not Fellow) in most cases. But some societies insist on Fellow, so it’s important to double check.

first-years

Note hyphen. Same for second-years, third-years and fourth-years

fiscal year

Do not capitalize when spelled out. When abbreviated, capitalize FY. For example:

  • She planned to give all of her lottery winnings to the university in fiscal year 2006
  • The university’s FY16 budget will reflect her generous donation

follow up

(v.)

follow-up

foreign words

Use italics. We follow CMS style, which suggests italicizing only those foreign words that are unfamiliar or do not appear in an English dictionary. Some words/terms may need to be decided on a case-by-case basis.

found that

In reporting research results, use “that” with found: Researchers found that losing a partner in a harmonious marriage puts you at greater risk of health problems (not, Researchers found losing a partner ...).

fractions

  • Spell out amounts less than one, e.g. one-half, two-thirds
  • Wherever practical, use figures for precise amounts larger than one and convert to decimals. e.g. 2.5 pounds
  • When spelling out amounts larger than one, hyphenate only the fraction, e.g. two and one-half pounds
  • Also acceptable: two and a half (no hyphen)

Friends of the Children’s Hospital at Yale New Haven

This is the organization’s full name.

full-time (adj.)

Use hyphen, e.g. He has a full-time job.

full time (adv.)

Do not use hyphen, e.g. She works full time.

fundraiser, fundraising

One word.

G

grand rounds

Set in all lowercase.

gender

Avoid using he or she for a generic person. If you must, alternate he and she.

For general information: https://medlineplus.gov/genetics/

To search for a gene, protein, etc.: https://www.ncbi.nlm.nih.gov/gene

Hugo Gene Nomenclature Committee (HGNC) guidelines for human gene nomenclature: https://www.genenames.org/about/guidelines#Appendix1

Greater Bridgeport, Greater New Haven

Uppercase “Greater.”

H

Harvey Cushing/John Hay Whitney Medical Library

This is the full name of the medical library. Cushing/Whitney Medical Library is acceptable on first reference.

headlines

  • Online YM stories should be title case (all main words initial caps.) In publications and in publications online, only the first letter of a headline should be capitalized unless a proper name or title is included (sentence case). Make all headlines flush left. Exception: First word after colon is always uppercase in headlines.
  • Attribute carefully. Attribution is as important in headlines as in stories.

headers (as opposed to headlines)

Web headers and newsletter headers or columns should be front-capped.

health care

Always use as two words, e.g. Her position as a health care worker is rewarding. e.g. Yale New Haven Hospital provides the finest health care. The exception is if “Healthcare” is part of a proper name.

Yale Medicine magazine and Medicine@Yale use health care as two words in all cases.

historic, historical

Precede with a, not an.

HIV

The main immunodeficiency virus that causes AIDS. (HIV virus is redundant.)

homepage

Two words

honorifics and titles

  • In most cases, Yale Medicine, the clinical practice, uses clinical titles rather than faculty titles in stories (although it uses some academic titles in concepts.)
  • On first reference, include a person’s academic degree(s) after his or her name: John Jones, MD, not Dr. John Jones. On second reference: Dr. Jones.
  • Following Names: Lowercase titles when they follow names: Robert Alpern, dean of the Yale School of Medicine. An exception is made for endowed-chair titles (see chairs, endowed chairs). Titles of faculty members of the Department of Internal Medicine omit the word internal: John Smith, professor of medicine. Also, note style for titles of faculty associated with the Cancer Center, Child Study Center: John Smith, of the cancer center; David Doe, a faculty member in the Child Study Center. Delete at Yale when this is obvious from the context: Deputy Dean Carolyn W. Slayman, PhD, Sterling Professor of Genetics and professor of cellular and molecular physiology at Yale (delete “at Yale” here).
  • Preceding Names: Capitalize titles when they precede names: Medical Director John Leventhal, Yale President Richard C. Levin, Dean Robert J. Alpern, MD.
  • Subspecialties: Many faculty titles include the individual’s subspecialty (section name) in parentheses: Gerald Shulman, MD, PhD, professor of medicine (endocrinology). To avoid awkward constructions, one may write instead: Gerald Shulman, MD, PhD, a professor of medicine and endocrinology or endocrinologist Gerald Shulman, MD, PhD, a professor of medicine.
  • Two or more titles: Use the minimum number of titles for a faculty member, per context. When a faculty member is in multiple departments, use “of” before each one to avoid confusion. Examples: John T. Stitt, PhD, professor of epidemiology, and of cellular and molecular physiology. A. Fictitious Physician, MD, professor of obstetrics and gynecology, and of epidemiology and public health.

house staff

Use as two words, lowercase

hyphen and compound words

When a compound modifier (two or more words that express a single concept) precedes a noun, use hyphens to link all the words in the compound except the adverb very and all adverbs that end in ly. (a well-known physician, a very good time, a highly trained lab technician, an easily remembered rule).

hyphenated words  

  • Hyphens are used to link words that function as a single adjective before a noun. You can use multiple hyphens: over-the-counter medicine. But beware of using more than two hyphens in a modifier. Use common sense to make sure text is not cumbersome. Example: Use HIV-positive to HIV-positive transplants, NOT: HIV-positive-to-HIV-positive.
  • When a hyphenated word begins a sentence, the first word is always capitalized; subsequent elements are not capitalized.
  • Hyphenate: well-being, high-quality, world-class, high-risk, low-risk, low-income, cost-effective, man-made, not-for-profit, pre-eminent (or any word in which the ending vowel of the prefix is the same as the beginning vowel of the next word).
  • Don’t hyphenate: online, preadmission, psychosocial, multidisciplinary, readmission, underserved, uninsured and underinsured, wheelchair, nonprofit.
  • In a title or headline, when two words are connected by a hyphen, if both words would be capitalized without the hyphen, they still should be capitalized. For example, Three-Year Results From the Evolut Low-Risk TAVR Trial Show Promise is correct while Three-year Results From the Evolut Low-risk TAVR Trial Show Promise in not correct.

I

i.e.

May be used in place of “in other words” with a comma before but not after.

In Memoriam

Note that the ending is -iam, not -ium. The short articles about alumni and faculty who have died should include the person’s full name, followed by advanced degrees, house staff or fellowship years, etc. (with Yale years of graduation), age, place of birth, last place of residence, date and place of death, a brief life and career chronology and any major contributions the person made to his or her chosen field. Information about survivors is not included in the obituaries. If a bachelor’s degree was earned at Yale, it may be mentioned in the write-up, but it is not included in the opening paragraph with the advanced degrees. Stylewise, it is preferable to use the deceased’s name, rather than a pronoun, in the first sentence of the second paragraph.

in utero, in vitro, in vivo

Do not italicize.

internet, intranet

  • Lowercase internet, lowercase intranet
  • Do not use “the Net”

institute

Lowercase when referring to NIH or a component (the institute, not the Institute). On first reference use National Institutes of Health (NIH) [note plural]

This is the full name (note that there is no hyphen between Sloan and Kettering). The Sloan Kettering Institute is the basic science research arm of the Cancer Center.

middle initials

When there are two initials, set with no space between them: Benjamin K.S. Piper. Follow the individual’s preference regarding middle initials, i.e., if a faculty member has a middle initial but does not want to use it, do not use it. Similarly, if a nickname is preferred, use the nickname. Otherwise, always include middle initials in names in body text, but do not include them in headlines, callouts, photo captions or photo credits. Example: In photo caption, use John Curtis; in body text, use John D. Curtis for first reference.
