Spell out acronyms on the first reference and use initials for each reference afterward. For example: nurses use best practice guidelines (BPG) to improve patient care. To date, there are more than 50 BPGs.

Note there is no "s" within the brackets even though you're identifying something that is plural. The acronym remains singular on the first reference, and is pluralized thereafter. When pluralizing an acronym, simply add an "s", don't use an apostrophe.

Use only commonly recognized acronyms instead of creating new ones.
