Specimen Handling and Surgical Counts
This domain tests two tightly linked safety systems: the retained-item count and the chain of custody for tissue. Both are high-stakes and highly testable because a single omission - one uncounted sponge, one specimen in the wrong fixative - causes real patient harm and is fully preventable.
Counted items and count times
Count sponges (including radiopaque markers, peanuts, and raytex), sharps (needles, blades, pins), and instruments. Counts are performed audibly by the scrub person and circulator together and recorded. Required count times: baseline before incision, before closure of a body cavity, before skin closure, whenever a cavity is closed, at any change of scrubbed or circulating staff, and at the end of the case. A count is never delegated to one person.
Discrepancy protocol
If a count is wrong: stop, notify the surgeon, and hold closure. Search the field, the drapes, the trash, and the floor. Recount with the same two people. If the item is still missing intraoperatively, an intraoperative radiograph is obtained and read before the patient leaves the room. Document the discrepancy, the search, and the outcome.
Specimen handling
Verify patient identity and label at the point of collection, not later. The label carries patient identifiers, specimen source and site, laterality or orientation if relevant, the type of tissue, and date and time. Orientation is marked by the surgeon with suture or ink and stated aloud. Fresh or frozen-section specimens go dry or on saline in a labeled container - never in formalin, which fixes the tissue and ruins the frozen section. Permanent specimens go in 10% formalin. Cultures go into a sterile container with no fixative. Specimens are handed off directly to the circulator, logged, and transported with a requisition; a specimen is never discarded, even if the surgeon says it is not needed.
Worked example
A surgeon excises a breast lesion and asks for a frozen section to check margins. The correct action is a dry, labeled container handed off immediately with the requisition marked frozen section. If the tech drops it in formalin out of habit, the pathologist cannot cut a frozen section and the patient may need a second operation.
Traps that cost marks
Formalin on a frozen-section specimen; labeling after the patient leaves; recounting alone; assuming a small sponge does not need counting; discarding a specimen the surgeon calls unimportant.
