Why Errors Happen

Common Mistakes: Verifying a Prescription Order

These are the specific ways this task goes wrong on the job — not hypothetical edge cases, but patterns that cause real dispensing errors, insurance problems, or patient safety issues.

1

Assuming two bottles with the same drug name and strength are interchangeable without checking the NDC — different manufacturers and package sizes have different NDCs, which matters for insurance billing and recall tracking.

2

Reading an expiration date as month/day instead of month/year or vice versa under time pressure.

3

Not re-checking the order after an interruption (phone call, question from another coworker) — resuming from memory instead of re-reading the order is a common source of errors.

How the Quality Checkpoints Prevent These

Every mistake above is caught by one of this task's quality checkpoints — the habit of checking these consistently is what actually prevents the error, not just knowing it exists.

  • ✓

    NDC match is done at the number level, not just drug-name-and-strength.

  • ✓

    Expiration date gives the patient a reasonable margin past the expected end of therapy.

  • ✓

    Lot number is documented wherever the pharmacy's SOP requires it.

  • ✓

    Discrepancies are flagged, not resolved by assumption.
