Medical transcription errors involving medications must be treated as documentation fidelity failures. Before approval, it is necessary to confirm what was said, by whom, and in what context. A practical review has two passes: first, identify the high-risk mentions; then check each one using the NAME–NUMBER–TIME–MEANING–SOURCE matrix. A draft may appear coherent and still contain errors. An analysis of dictated clinical documents using speech recognition underscores the importance of human review, but its findings do not measure the performance of another product, language, or setting. Zhou et al., 2018
Scope: documentation fidelity, not therapeutic validation
Before clinical use, technical leadership should confirm with qualified professionals which rules and guidance are in force for the workflow, specialty, and context. Until that validation is complete, use clear patient information, complete physician review, auditing, monitoring, and the ability to stop use as minimum safeguards.
This checklist answers a defined question: did the draft accurately reproduce the name, dosage form, concentration, dose, unit, route, frequency, duration, and meaning of what was said? It does not assess indication, contraindication, interaction, dose appropriateness, or clinical management. A sentence may be faithfully documented and still require clinical reassessment.
The NAME–NUMBER–TIME–MEANING–SOURCE matrix
Use the matrix as a visual index for every medication mention:
| Axis | Review question | What to check |
|---|---|---|
| NAME | Which medication was mentioned? | Active ingredient or brand, dosage form, and concentration |
| NUMBER | Was the value reproduced without alteration? | Dose, concentration, unit, zero, and decimal place |
| TIME | How and when is it used? | Route, frequency, interval, duration, and condition |
| MEANING | Does the sentence preserve the original intent? | Affirmation, negation, hypothesis, history, plan, and third party |
| SOURCE | Where did the information come from? | Spoken excerpt, speaker, list, prescription, or official reference |
The order makes review easier, but SOURCE applies across every axis. A list, prescription, or official reference may help confirm spelling and dosage form; it must not replace the content that was actually provided. If there is a discrepancy, keep the item pending instead of choosing the most plausible version.
Pass 1: scan without correcting
On the first pass, only identify the excerpts that will require verification. Correcting as you read may divert attention from other mentions.
Mark:
- medication names, active ingredients, brands, and abbreviations;
- allergies, intolerances, and reported reactions;
- verbs such as start, continue, adjust, hold, discontinue, and restart;
- numbers, units, concentrations, and dosage forms;
- routes, intervals, duration, and conditions such as “as needed”;
- negations, hypotheses, and medications attributed to third parties.
Preserve the surrounding sentence and identify who spoke. An isolated word may not show whether the medication is current, previous, being considered, denied, or used by someone else.
Pass 2: compare the draft with the sources
Review each marked item in a short cycle:
- retrieve the spoken excerpt and identify the speaker;
- compare the name, number, unit, time, and meaning verbatim;
- check an available list, prescription, or official reference to confirm spelling and dosage form;
- correct only what has been confirmed;
- refer questions to the physician responsible for the patient’s care.
Zhou et al. analyzed dictated clinical documents produced with speech recognition support and reported errors at different stages, highlighting the need for manual review. The study was conducted in a specific setting and does not provide a rate transferable to Brazilian Portuguese, AI scribes in general, or Zello Life. Zhou et al., 2018
If the excerpt is unavailable or remains inaudible, do not normalize the gap. Flag the pending issue and clarify the information before clinical approval.
NAME: check the medication, dosage form, and concentration
Names with similar spelling or sound require specific attention. ISMP Brazil compiles examples of this risk, and the World Health Organization maintains a publication dedicated to look-alike and sound-alike medication names. ISMP Brazil, 2014 WHO, 2023
Entirely synthetic examples; they are neither prescriptions nor dosing references.
| Case | Spoken content | Draft | Risk | Review action |
|---|---|---|---|---|
| Synthetic 1 | “The previous document lists Medication Alpha.” | “It lists Medication Alva.” | Swap between similar fictitious names | Compare the excerpt with the available source; do not decide based on the clinical context |
| Synthetic 2 | “The external document mentions Medication Beta.” | “The document mentions Medication Zeta.” | Substitution of the reported name | Check the cited document and keep the uncertainty explicit until confirmation |
| Synthetic 3 | “Medication A, 2 mg/mL solution.” | “Medication A, 2 mg tablet.” | Dosage form and concentration altered | Review dosage form and concentration as separate fields |
The goal is not to choose which option would make more sense for the condition. It is to verify which name, form, and concentration were actually provided. All cases are synthetic, contain no patient data, and have no dosing purpose.
NUMBER: read the value, decimal, and unit together
Zeros, decimal places, units, and concentrations must be checked together. The Brazilian protocol addresses the need for clear notation to reduce ambiguity in medication documentation. Ministry of Health, Anvisa, Fiocruz, and FHEMIG, 2013
Entirely synthetic examples; the values illustrate documentation errors and do not provide dosing guidance.
| Case | Spoken content | Draft | Risk | Review action |
|---|---|---|---|---|
| Synthetic 4 — 8/80 | “Eight milligrams.” | “80 mg.” | Addition of one digit | Confirm the value and unit together |
| Synthetic 5 — mg/mcg | “Fifty micrograms.” | “50 mg.” | Unit differs from what was said | Do not convert silently; document only the confirmed unit |
| Synthetic 6 — 0.5/5 | “Zero point five milligrams.” | “5 mg.” | Omission of the decimal | Check the complete reading before correcting |
| Synthetic 7 — mg/mL | “Solution at two milligrams per milliliter.” | “2 mg.” | Concentration documented as a dose | Separate concentration, volume, and amount only when they were provided |
During the final read, read the number with its unit. Do not round, convert, or add data to make the text more polished. The examples are synthetic and do not provide guidance on actual doses.
TIME: preserve route, interval, duration, and condition
Under the TIME axis, also review the route. Expressions such as “once a day,” “every eight hours,” “for five days,” and “as needed” are not equivalent. Route, frequency, and duration are among the elements addressed by the Brazilian protocol. Ministry of Health, Anvisa, Fiocruz, and FHEMIG, 2013
Entirely synthetic examples; do not use these sentences as therapeutic guidance.
| Case | Spoken content | Draft | Risk | Review action |
|---|---|---|---|---|
| Synthetic 8 — route | “For subcutaneous use.” | “For cutaneous use.” | Change in route | Confirm the complete word in the original excerpt |
| Synthetic 9 — interval | “Every eight hours.” | “Eight times a day.” | Interval converted into a count | Preserve the confirmed wording without recalculating the frequency |
| Synthetic 10 — condition | “Once a day, as needed.” | “Once a day.” | Omission of the condition | Restore the condition only after confirmation |
| Synthetic 11 — verb tense | “Stopped it two days ago.” | “Stop it for two days.” | History converted into a plan | Check the verb, time reference, and who made the decision |
If the spoken content includes only “twice,” with no period or condition, do not complete it as “a day.” Keep the gap pending. All cases are synthetic and do not constitute instructions for use.
MEANING: review negations, hypotheses, and attribution
Before clinical use, technical leadership should confirm with qualified professionals which rules and guidance are in force for the workflow, specialty, and context. Until that validation is complete, use clear patient information, complete physician review, auditing, monitoring, and the ability to stop use as minimum safeguards.
Short words can change the meaning of a sentence. Classify the mechanism correctly: adding a negation is an insertion; removing a negation is an omission; replacing one term with another is a substitution. These mechanisms must not be grouped as though they were the same error.
Entirely synthetic examples; they do not represent real clinical decisions.
| Case | Spoken content | Draft | Risk | Review action |
|---|---|---|---|---|
| Synthetic 12 — negation | “Does not take an anticoagulant.” | “Takes an anticoagulant.” | Omission of the negation and reversal of meaning | Check the negation and the speaker |
| Synthetic 13 — ambiguous response | “Allergic to Medication B?” Response: “uh-uh” | “Denies an allergy to Medication B.” | Meaning assigned without confirmation | Clarify the response instead of inferring |
| Synthetic 14 — third party | “My mother takes Medication C.” | “Patient takes Medication C.” | Use attributed to the wrong person | Identify the referent and speaker |
| Synthetic 15 — hypothesis | “If it persists, we may consider Medication D.” | “Start Medication D.” | Possibility converted into a decision | Distinguish among a condition, discussion, and confirmed plan |
Frequently asked questions
How should a medical visit transcript involving medications be reviewed?
Use two passes. On the first, mark medications, numbers, routes, frequencies, allergies, negations, and changes in use. On the second, compare each marked item with the spoken content and available sources using NAME–NUMBER–TIME–MEANING–SOURCE.
Can AI confirm that the name and dose are correct?
Not automatically. The name, value, unit, dosage form, and context must be checked. Reviewing the medication content is the responsibility of the physician responsible for the patient’s care.
What should be done when it is impossible to distinguish mg from micrograms?
Do not choose the most plausible alternative. Flag the uncertainty, check the available sources, and clarify the information before completing the document.
How should similar medication names be checked?
Compare the spoken term with the active ingredient or brand, dosage form, and concentration. An official reference may confirm the spelling, but it must not replace what was actually provided. ISMP Brazil compiles examples of this risk. ISMP Brazil, 2014
Can a short response such as “uh-uh” be documented as a negation?
Only if its meaning is unambiguous in context. If there is uncertainty, clarify the response instead of assigning meaning to the sound.
Does checking the transcript validate the prescription or clinical management?
No. The check verifies documentation fidelity. Indications, contraindications, interactions, and therapeutic decisions require their own clinical assessment. The physician responsible for the patient’s care also decides whether the content may become part of the medical record.
