Which stage accounts for the highest percentage of medication errors?

• A. Transcription
• B. Nurse administration
• C. Prescribing by the doctor
• D. Dispensing by pharmacy

Answer: (A)

Transcription is a particularly vulnerable point because it’s the moment orders are converted into a patient record or medication administration record and handed off to pharmacy and nursing staff. This conversion relies on accurate interpretation and data entry, so legibility, clarity, and correct details are all essential. A small misread or a decimal point error, a look-alike drug name, or missing information about dose, route, or frequency can create a wrong medication or incorrect instructions, and that error can propagate through dispensing and administration. Because every subsequent step depends on what was transcribed, mistakes here tend to appear as a large share of medication errors in many settings, making transcription the most impactful stage in this context. Using clear, standardized orders, electronic prescribing, barcoding, and double checks helps reduce these errors by cutting down on miscommunication at this critical transfer point.
