What are two patient identifiers commonly required to confirm identity in the perioperative setting?

• A. Full name and date of birth
• B. Room number and diagnosis
• C. Medical record number alone
• D. Height and weight

Answer: (A)

Two identifiers are used to confirm a patient’s identity before any perioperative step to prevent wrong-patient events. The standard combination is the patient’s full name and date of birth. These two pieces of information are unique to the individual, are typically available on the ID band and the medical record, and can be verbally confirmed with the patient or their chart to ensure you’re matching the right person to the procedure.

Why this pair works well: names and dates of birth are stable identifiers that most patients can confirm, and they’re commonly documented in multiple reliable sources (ID bracelet, chart, preop notes). This makes verification straightforward and reduces the risk of mixing up patients.

Why the other options aren’t suitable as the two identifiers: room number can change and isn’t unique to the patient, diagnosis varies and isn’t specific to identity, and a medical record number alone is just one identifier. Height and weight are unrelated to patient identity and don’t reliably confirm who is on the table.

Always verify identity with the patient if possible, using two identifiers, and pause if there’s any doubt or mismatch.
