Purpose of the Count
Surgical counts exist to prevent retained surgical items (RSI), one of the most serious and preventable "never events" in surgery. The scrub and circulator share joint accountability for every counted item on the sterile field from setup through closure. AORN standards and most facility policies require counts before the procedure begins, before closure of a cavity within a cavity, before wound closure, at skin closure, and at any change of scrub or circulating personnel.
What Gets Counted
- Sponges - radiopaque raytec, laparotomy (lap) pads, peanuts/kitner dissectors, tonsil sponges.
- Sharps - suture needles, hypodermic needles, scalpel blades, safety pins, electrosurgical tips if specified by policy.
- Instruments - counted for procedures entering a body cavity, and any time miscellaneous small parts (screws, trocars, wing nuts) are used.
- Miscellaneous items - vessel loops, umbilical tapes, guidewires, and other small items per facility policy.
When Counts Are Performed
| Count Point | Timing |
|---|---|
| Baseline (initial) count | Before the procedure begins, before the incision |
| First closing count | Before closure of a cavity within a cavity (e.g., uterus before abdominal wall) |
| Second closing count | Before closure of the primary cavity or deep tissue layer |
| Final (skin) count | At skin closure or the end of the procedure |
| Relief count | Any time scrub or circulator personnel changes |
Counting Method
- Counts are performed out loud by two people - typically the scrub person and the circulator - simultaneously viewing each item.
- Count in a consistent, systematic order: back table, then Mayo stand, then the sterile field, then the wound.
- Sponges are counted in packages of a standard number (commonly 5 or 10) and any package that does not contain the standard number is removed from the field immediately and set aside.
- Items added during the case (relief sponges, additional needles) are counted aloud and documented the moment they enter the field.
- The circulator documents each count on the intraoperative record in real time.
Resolving a Count Discrepancy
An incorrect count is a patient safety event that must be resolved before the surgeon closes further, if at all possible.
- Notify the surgeon immediately.
- Recount the item category in question.
- Search the sterile field, back table, floor, trash, and linen.
- If the item is still not found, the surgeon may order an intraoperative X-ray to rule out a retained item.
- Document the discrepancy, the search process, and the resolution (including X-ray results) on the intraoperative record and per facility incident-reporting policy.
Key Exam Points
- Counts are a shared responsibility, but the surgeon is ultimately responsible for the patient - the count does not relieve the surgical team of vigilance.
- An "incorrect" count does not automatically mean an item is missing from the room - it means what was counted does not match what should be present, and it must be investigated regardless of time pressure.
- Never discard sponges, needles, or instruments from the room until the count is confirmed correct and the surgeon has closed.
- Standardized counting sequences reduce errors caused by distraction and interruption; audible, unambiguous communication is essential.
- Radiopaque markers in sponges allow radiographic detection if a sponge is unaccounted for at the end of a case.
