Abbreviations, Acronyms, Initialisms
If a term or an organization’s name will be used more than once, spell it out the first time, followed by its abbreviation in parentheses. Afterward, use the abbreviation (10.3, 10.24, 10.26) in text and heads.
I work at the California Health Care Foundation (CHCF). The CHCF office is in Oakland.
But treat an executive summary or a sidebar as an independent document for purposes of abbreviations.
Rewrite to avoid making an acronym possessive, but if a phrase is introduced in the plural, write its acronym in the plural: Health Maintenance Organizations (HMOs).
Omit internal punctuation (10.20) with academic degrees (MD, MS, PhD, RN) and generally do not use other credentials (CMT, FACP, etc.) unless important to topic of report.
an eight-year-old boy
six- to 12-year-old kids
people age 65 (not aged)
65 or older
five years old
age 65+ or >65 (okay in graphics)
On title page, list only names, degrees (Madelyn Walters, MS, MPH), and organization.
In the “About the Author” section, list names, appropriate degrees, title, and organization:
Al Malamute, PhD, MD, director of surgery, Stanford University Hospital
Any brief, factual description (up to 50 words) should not be promotional in tone.
To avoid gender bias, use these strategies (5.252):
- If possible, rewrite to avoid him and her, or recast in the plural: a doctor must wash his hands often becomes doctors must wash their hands often.
- Use nonsexist words instead of “man” words: people not mankind, chair not chairman.
When referring to someone with a disease, emphasize the person, not the disease (5.260): a patient with diabetes (preferred) or a diabetic patient. Never employ as a noun: diabetics, schizophrenics, or the like.
Capitalize generic terms as part of proper names, but lowercase them in references (8.51, 8.66, 8.68): California Health Care Foundation, the foundation; the Department of Disease Eradication, the department; Stanford University, the university. But see Places.
Names of companies or brands that start with a lowercase letter followed by a capital (eConsult) don’t need to be capped when they start a sentence, although some editors may want to reword (8.154).
Use these guidelines for headings and the titles of books, journals, articles, etc. (8.159).
- Always capitalize the first and last words of a title and subtitle, and capitalize all other major words, including nouns, pronouns, verbs, adjectives, adverbs, and some conjunctions, except as noted below.
- Lowercase articles: a, an, the.
- Lowercase prepositions of four or fewer letters: for, in, of, on, with but Above, Between, Through, Within.
- Lowercase the conjunctions and, but, for, nor, and or.
- Lowercase to as a preposition and as an infinitive (to Examine); lowercase as.
- For hyphenated words (8.161), capitalize both elements: Follow-Up Report.
- Lowercase words in parentheses.
Citations and References
For citations, use endnotes, not footnotes (except in almanacs and when necessary in sidebars). Apply arabic numbering (1, 2, 3) and use Microsoft Word’s Reference feature, which will number notes automatically.
All endnote numbers should be superscripted and usually follow the sentence’s final punctuation.
Use italics for report titles and any landing pages; use roman type and quotation marks for other kinds of web pages.
Use Digital Object Identifiers (DOIs) whenever available (14.8), mostly for some journal articles. Use them both in External Links and in reports. In notes, append “doi” with a colon and the DOI, with no intervening space: doi:10.28530/fj05472g. For links, use this format: https://dx.doi.org/[DOI] (https://dx.doi.org/10.28530/fj05472g).
For help with legal citations, consult The Indigo Book.

Avoid using multiple endnote numbers.1,2 Instead, use one endnote number and separate multiple sources with semicolons:1
- Dan Forth, How Doctors Treat: A Survey (New York: Knopf, 1967), 48–52; Jordan Futon, “Health Care in Rural Japan,” Asian Health 24, no. 3 (March 2011): 324.
Use the full name, including ampersands and abbreviations, but you usually may omit Inc., & Co., LLC, and the like (10.23): Merck not Merck & Co. Inc. If the context requires such specificity, omit any preceding comma (6.44): WeCare Health Plan Inc.
Use these guidelines for the titles of books, articles, websites, etc.
Initial the: An initial the in the title of a newspaper or periodical is lowercased (unless it begins a sentence) and not italicized (8.170): the New York Times.
Subtitles: Use a colon to separate a subtitle from a title (8.164): The Avocado Diet: Lose Weight and Help California’s Economy.
Websites, surveys, and databases
Capitalize, but do not italicize or surround with quotation marks (8.191):
This year, PubMed is expected to serve up a billion page views.
Surround the title of a web page with quotation marks (8.191):
Visit “2014 Postpartum Depression Survey Data” for more details.
See also Capitalization.
- Capitalize and spell out months in running text. In tables, notes, and the like, use three-letter abbreviations with periods (10.39): (November, Nov.).
- If no date is specified, do not use a comma after the month (6.38): March 2001.
- If a date is specified, use commas after both the date and the year (6.38): On April 2, 2001, the nurses met.
- Use ordinal numerals (9.31): June 30 not June 30th.
- Centuries: Spell out and hyphenate (9.32): the twenty-first century.

When explanatory footnotes are required, use these symbols in this order (14.49): * (asterisk), † (dagger), ‡ (double dagger). If more footnotes are needed, double the symbols: **, ††, ‡‡.

Illustrations (Tables and Figures)
All illustrations require a title and a source notation at the bottom that includes the year.
Illustrations should be numbered continuously. Tables are numbered separately from other figures such as graphs and illustrations. Appendices are lettered. (Table 1, Table 2, Figure 1, Table 3, Figure 2. Appendices A, B, C.) A table or figure within an appendix includes the appendix’s letter (Table A1, Figure B1).
Notes for illustrations belong below the illustration and not in the endnotes. Illustration notes use these symbols in this order (3.79): * (asterisk), † (dagger), ‡ (double dagger), § (section symbol), ∥ (parallels), # (number sign). If more are needed, use double marks in the same order: **, ††, ‡‡, §§, ∥∥, ##.
Figure and table numbers are separated from captions by periods, appendices by colons. Use title case for captions. Use terminal punctuation if at least most captions in a document are full sentences.
Figure 1. Care Connection Team
Table 2. Current Rural Palliative Care Pilots in California
Appendix B: Emerging Community-Based Palliative Care Models in Rural California

Use periods and a space between initials (A. B. Cooper) but omit periods and spaces in names replaced by initials (10.12): JFK.
On first reference, use the person’s first and last names. In subsequent references, use only the last name: Jan Jackson then Jackson; Mortimer Brown, MD, then Brown [not Dr. Brown].
See also Company Names.
When designating a range, use to if the second entity is not included and through if it is: 2011 to 2015 does not include 2015 whereas 2011 through 2015 does include 2015.
At the beginning of a sentence — unless it’s bulleted — either spell out a number or reword the sentence (9.5).

In graphs and charts, use symbols to denote “less than,” “through,” “and above,” and the like: <18, 18–25, 26+.
Use an italicized capital N to represent population size, an italicized lowercase n to represent subpopulation size (3.85).

Use numerals, except at the beginning of a sentence (unless it’s bulleted), and don’t hyphenate even in adjectival form. Use the percent symbol (%) throughout except at the beginning of a sentence (9.18); use less and more as modifiers.

Words such as state, county, city, and so forth are capitalized when they are used as an accepted part of a proper name, even when pluralized (8.51, 8.53): Alameda County, Marin and Napa Counties, Washington State, Southern California but southern Idaho.
Punctuation and Spacing
Capitalize a word that follows a colon only if it starts a complete thought (6.63).
Include these items: aspirin, gauze, and tape.

For number ranges, use an en dash: 2004–2007, pp. 4–9.

Form an em dash with Ctrl+Alt+Numpad minus, and add a space before and after: Several sources — Health Affairs, TIME, and Newsweek.
I will apply . . . all measures that are required. . . . I will remember that there is art to medicine as well as science.
Parentheses and brackets
Always use in pairs, even in run-in lists (6.129): (1) California, (2) New York.
When making a parenthetical statement within another one, use brackets for the innermost set (6.99).
