Surgical Safety Checklist

CST SURGICAL TECH

Definition

WHO three-phase verification (Sign In, Time Out, Sign Out) to prevent surgical errors.

Documentation

Surgical documentation for surgical safety checklist includes: operative consent verification, time-out confirmation (correct patient, correct site, correct procedure), specimen labeling and pathology requisition, instrument and sponge count results, and any implant records with lot numbers and serial numbers. All counts must be documented as correct or incorrect with follow-up actions.

Step-by-Step Procedure

Procedural steps relevant to surgical safety checklist in the surgical setting:

  1. Initial count performed before incision: sponges, sharps, instruments, miscellaneous
  2. Closing counts: first closing count (deep layers), second closing count (skin closure)
  3. All counts are audible, visual, and concurrent (scrub tech and circulator together)
  4. Sponges counted in groups of 5, radiopaque sponges only used on the field
  5. Incorrect count protocol: notify surgeon then recount then wound search then X-ray if unresolved
  6. Sharps counted on a needle counter/magnet, broken needles: account for all pieces
  7. Add-on items must be counted when added and at subsequent count times

Patient Communication

Clear communication about surgical safety checklist with patients, families, and the healthcare team is essential. Use standardized handoff tools (SBAR) for shift changes and transfers. Verify understanding by asking the patient to repeat key information back to you.

Differential Diagnosis

When studying surgical safety checklist, carefully distinguish it from related but distinct concepts: patient identification, sterile technique. Exam questions often test your ability to select the most specific and appropriate answer when multiple options seem partially correct. Look for the option that most completely addresses the scenario presented.

Troubleshooting

When surgical safety checklist does not go as expected, systematically review each step of the procedure. Check equipment calibration, verify technique, and repeat the measurement if results seem inconsistent with the clinical picture. Report discrepancies to the supervisor rather than guessing at the correct value.
