The question

Mrs Smith has been on the ward four days and every nurse knows her, so why do they still ask her name and date of birth every single time?

Understand

Two patients called Mrs Smith on one ward: why nurses ask you to say your name and date of birth every time, and match it to your wristband and chart. Rules vary between hospitals and between Australia and New Zealand: follow your local policy.

  1. Names aren't unique: two patients with the same or similar name can be on one ward.
  2. A yes/no question like "Are you Mrs Smith?" can be answered yes by both of them.
  3. So staff ask the patient to say them, then match the answer to the wristband and chart.
  4. Three identifiers together (name, date of birth, MRN) fit only one person.

Key takeaways

  • Before care, medicines, tests or procedures, use at least three approved identifiers.
  • Ask the patient to say their full name and date of birth; don't read it out and ask "is that right?".
  • Match the answer to the wristband and the chart, every time, even with a patient you know.
  • Mismatch, wrong band or no band: stop, and tell your supervising nurse or the nurse in charge.

In practice

  • Ask: "Can you tell me your full name and date of birth?"
  • Match the answer to the wristband and the chart.
  • Check the MRN on the band against the chart.
  • Mismatch or no band: don't give the care. Tell your supervising nurse or the nurse in charge.

In one line

Asking isn't about whether the nurse knows you: it checks that you, your wristband and your chart all match, every time, before care is given.

Check yourself

Two Mrs Smiths are on the ward. A nurse asks one, "Are you Mrs Smith?" and she says yes. Is that a safe check?

Show the answer

No: both would say yes. Ask her to say her full name and date of birth, then match it to her band and chart.

Got it? Nice. Kip's proud of you.

Can you tell me your full name and date of birth? Again, love? Four days you've known me! So why do nurses ask, every single time, even when they know you?

Because names aren't as unique as they seem. Last night, another Mrs Smith arrived, two beds down. Two patients with the same or similar names on one ward raise the risk of a mix-up.

And a mix-up can mean the wrong medicine, the wrong test, or even the wrong procedure. So if the nurse asks, 'Are you Mrs Smith?', is that a safe check?

Three. Two. One. No. Both of them would say yes, and both would be right.

That's why staff ask you to say your name and date of birth, instead of reading them out. Think of it like a lock with three dials.

One dial, her name, matches both Mrs Smiths. Add her date of birth, and her medical record number, the hospital's own number for her, and all three fit only her.

Unlike a lock, a patient can't always answer. If she's too unwell or confused, a family member or a second staff member may confirm it instead, as local policy says.

Australian hospital standards require at least three approved identifiers whenever care or medicines are given. Her bed number isn't one of them: it belongs to the bed, not to her.

She says her name and date of birth, and her answer is matched against her wristband and her chart. So asking isn't about whether the nurse knows you.

Knowing her face doesn't check the chart, or the test in Alex's hand. It checks that you, your wristband and your chart all match, every time, before care is given.

Nursing students, like Alex: same check, even with a patient you've had all week. If her answer, band and chart don't all match, or there's no band, don't give the care: stop and tell your supervising nurse or the nurse in charge.

And if you're the patient, and your band is wrong, tell staff. Right, Mrs Smith. One more time? Margaret Smith, third of April, nineteen forty-seven!
