- Authentication
- The admissible evidence channels are something-held (a wristband encoding the patient's identifier) and something-inherent-plus-attested (the patient's own verbal confirmation of name and date of birth, attested against the chart) — a deliberately two-channel procedure.
This sourceDocuments the WHO pre-operative time-out, a multi-channel patient-identification procedure (wristband plus verbal confirmation against the chart) anchored at admissions intake.

Supports only that the WHO checklist includes an oral confirmation of patient identity before incision; wristband, date-of-birth and chart-attestation channels are not described.
“oral confirmation, immediately before incision, of the identity of the patient, the operative site, and the procedure to be performed”

Haynes et al. support only the last item, surgeons adopting a safety checklist; the other adoption episodes (writing, pilots, notebooks, notation) are outside this source.
“The checklist consists of an oral confirmation by surgical teams of the completion of the basic steps for ensuring safe delivery of anesthesia”

- Confirmation Dialog
- Confirmation dialogs in software ("Are you sure you want to delete?"), the surgical pre-incision timeout, the launch second-key protocol, cooling-off periods in consumer credit, the legislative second reading, and the aviation challenge-and-response checklist are all instances of the same pattern: introduce a structurally enforced moment of re-deliberation immediately before a step from which retreat is costly or impossible.

Haynes et al. document the pre-incision oral checklist as one instance; they say nothing about dialogs, launch keys, cooling-off periods or a general re-deliberation pattern.
“It is used at three critical junctures in care: before anesthesia is administered, immediately before incision, and before the patient is taken out of the operating room.”

- Turn Taking
- The prime makes the failure modes legible as structural, not personal: a room where a junior member never speaks up about a concern is Starvation of a quiet contender under a dominance-prone self-selection rule, and the documented fix is exactly the prime's family — switch rule families by instituting a checklist that pre-allocates a turn to each role ("anaesthesia, any concerns?"), converting contention into round-robin so the quiet contender is guaranteed the floor.

The WHO checklist is an oral team-confirmation routine with briefings and team introductions that improved outcomes; the paper does not describe pre-allocated per-role turns or silent juniors.
“At each site, implementation of the checklist also required routine performance of team introductions, briefings, and debriefings, but adherence rates could not be measured.”

Mechanisms¶
- Checklist Confirmation
- A well-designed checklist reliably converts "I think it's fine" into "I checked, and here's what the record said," and the discipline of a short pre-action confirmation is exactly what the surgical-safety-checklist literature credits for reducing avoidable duplicate and omission errors.

- Decision Checklist
- Its strength is friction at the right moment for almost no cost: a good checklist converts a decision type's hard-won lessons into a thirty-second pause that reliably catches the predictable slip, which is why short checklists cut error in domains from surgery to aviation.

- Intake Capacity Checklist
- Like the WHO Surgical Safety Checklist, its value is forcing a few non-negotiable checks before an irreversible step, catching predictable omissions rather than exotic ones.
This sourceUses the WHO Surgical Safety Checklist to require confirmation of a small set of critical safety steps at defined points before and during surgery, reducing common avoidable omissions and adverse outcomes.
- Like the WHO Surgical Safety Checklist, its value is forcing a few non-negotiable checks before an irreversible step, catching predictable omissions rather than exotic ones.
- Lesson-to-Routine Hardening
- Its strength is that it closes the gap between agreeing with a lesson and acting on it, by moving the behavior into a durable external form — the logic behind the safety checklist, which reliably prevents lapses on steps experts fully know but predictably skip under load.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 8 of 14 citations: 2 supported, 6 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
