Contamination Event Response

Clinical Objective

Establish a clear, no-blame protocol for recognizing, announcing, and responding to any contamination event during surgery, ensuring that the response is immediate and complete.

Why This Matters

An unannounced contamination event is the most common preventable cause of intraoperative SSI exposure. The cultural norm of immediate, blameless announcement is the only mechanism that catches these events in time.

Critical Control Points

• Any team member can call 'contamination' without hierarchy

• Response is immediate and proportional to the breach

• All events documented in the surgical record

Step-by-Step Protocol

1. 1

   Establish at the pre-case briefing that any team member may call a contamination event.

2. 2

   If contamination is observed or suspected, announce it immediately and clearly.

3. 3

   Pause the case at a safe point; assess the extent of the breach.

4. 4

   Determine the appropriate response: glove change, instrument exchange, drape addition, or re-prep depending on scope.

5. 5

   Resume the case only after the contamination has been fully addressed.

6. 6

   Document the event, response, and any follow-up monitoring plan.

Key Pitfalls

• Delaying announcement to 'not interrupt' the case — the consequence is far greater than the interruption.

• Partial response (changing one glove when both contacted contamination).

• Allowing hierarchy to suppress junior team members from speaking.

• Failing to document the event and response.
