Do-Not-Use List, Ambiguous Abbreviations, and Plurals Before a Survey
A 240-bed community hospital reviews order sets and transcribed reports 10 days before a Joint Commission survey. Four items are flagged: (1) "Regular insulin 5 U subcut qd" - pharmacy calls the prescriber about unclear insulin orders roughly twice a week. (2) A discharge summary in which "MS" appears three times: "MS noted on exam," "MS 2 mg IV push given for pain," and "history of MS." (3) "PT consult for gait training" filed the same day the laboratory reports "PT 18 seconds, INR 1.4." (4) A pathology report dictating "multiple diverticulum" and "both phalanx were fractured." The transcription vendor bills per corrected report, so the team must separate true safety risks from style issues before the survey.
1. Rank the four items by patient-safety risk and state the disposition of each.

Ranking (highest risk first):
- (1) Insulin order - true safety risk, fix today. "U" can be misread as a 0 or a 4, turning 5 units into 50 or 54 units; "qd" can be misread as "qid" (four times daily). Both are on the do-not-use list. Rewrite: "Regular insulin 5 units subcutaneously once daily."
- (2) "MS" - true safety risk. Three different referents in one document: mitral stenosis (exam finding), morphine sulfate (the 2 mg IV push), multiple sclerosis (the history) - and "mental status" is a fourth possibility. Each must be spelled out; the dose line is the one that could kill.
- (3) "PT" - communication risk, not a do-not-use item. Context makes it decipherable (gait training vs. prothrombin time), so it is a style/standardization issue: spell out on first use per document.
- (4) Plurals - documentation-quality issue. Wrong but not dangerous; the vendor charges per corrected report, so batch the fixes.
Disposition logic: do-not-use-list violations are corrected retroactively and reported; ambiguous-but-not-listed abbreviations are standardized going forward.
2. Rewrite items (1) and (3) so they would survive survey, and say why the rewrite of (3) is still worth doing even though it is not on the list.

(1) Rewrites:
- "Regular insulin 5 units subcutaneously once daily."
- Add the indication of timing (before meals / at bedtime) rather than "qd" variants - and never "U," "IU," "q.d.," "Q.D.," or trailing zeros (write 5 units, not 5.0 units).
(3) Rewrites:
- Physical therapy: "Physical therapy consult for gait training."
- Laboratory: "Prothrombin time 18 seconds (INR 1.4)."
Why (3) still matters: the do-not-use list is a floor, not a ceiling. Two abbreviations on the same chart with two referents create a read-back hazard when a nurse scans the flowsheet quickly - a PT value read as a PT consult, or vice versa, can delay anticoagulation or gait training. The surveyor's question is not "is this word on the list?" but "can a clinician misread this?" Standardizing on first-use expansion costs nothing and removes the question. Note the difference in accountability: (1) and (2) require correcting the existing record; (3) requires fixing the template that generates it.
3. Correct the two plurals in item (4) and give the rule set a transcription editor should apply, including one exception.

Corrections:
- multiple diverticula (diverticulum → diverticula)
- both phalanges were fractured (phalanx → phalanges) - and note the agreement error: "both" with a singular noun is the giveaway that a plural was intended.
Rules worth memorizing:
| Ending | Plural | Example |
|---|---|---|
| -a (Latin) | -ae | vertebra → vertebrae; bursa → bursae |
| -um | -a | diverticulum → diverticula; atrium → atria |
| -us | -i | bronchus → bronchi; nucleus → nuclei |
| -is | -es | diagnosis → diagnoses; anastomosis → anastomoses |
| -nx / -ynx | -nges | phalanx → phalanges; larynx → larynges |
| -oma | -omata (or -omas) | sarcoma → sarcomata / sarcomas |
Exception to flag: -us is not uniformly -i. virus → viruses (not viri), and apparatus → apparatuses/apparatus. Muscle terms follow Greek patterns instead: femur → femora but also femurs; thorax → thoraces.
Editor's shortcut: if the dictated sentence contains "multiple," "both," "bilateral," or a number greater than one, the following noun must be plural - check the ending, then check agreement. That single rule catches both errors in item (4).
