What is the purpose of using two identifiers for patient verification before procedures?

• A. To assess patient satisfaction.
• B. To ensure the correct patient, procedure, and site.
• C. To verify the patient's insurance eligibility.
• D. To confirm appointment time.

Answer: (B)

Two identifiers provide reliable confirmation of who the patient is. By requiring two independent data points—such as the patient’s full name and date of birth (or medical record number)—the team reduces the risk of mixing up patients, which is especially common in busy environments where names may be similar or records can be misfiled. This verification is done before any invasive procedure to ensure not only the patient but also the planned procedure and the correct surgical or treatment site are exactly as intended. This check is often part of a final time-out where the team confirms the patient’s identity, the procedure, and the site against the chart and consent. Other options—like assessing satisfaction, verifying insurance, or confirming appointment time—don’t directly prevent wrong-patient, wrong-procedure, or wrong-site errors.
