Approved Writing Style

Duke Health follows a modified version of AP Style. Here are some common style guidelines to remember.

Readability

  • Use plain language in your materials. The recommended reading level for materials is 7-8th grade.
  • Use the serial or Oxford comma in a series.
  • Use initial caps in headlines and subheads for readability.

Times and Dates

  • Use a.m. and p.m. (with periods) when referencing time. Use numbers, and omit the 00 on the hour times.
  • When a month is used with a date, abbreviate the month.
  • When it’s only the month and the year, spell out the month.

Addresses

  • Use abbreviations for road names and cardinal directions.
  • Suite and room can be spelled out as such.

Bulleted Lists

  • Capitalize the first word in a bulleted list. Use a period at the end if the bullet forms a complete sentence only.
  • Use square bullets.

Provider Titles

  • Medical degree should not have periods, and should be listed after the name.

URLs and QR codes

  • Use the shortest working url in text. Capitalize words in most cases, for easy readability.
  • When possible, QR codes should be Duke Royal Blue.
