Sterility Readiness Check

Clinical Objective

Verify that all instruments, implants, and sterilisation indicators are confirmed ready before the patient enters the OR — eliminating the conditions that lead to convenience-based immediate-use steam sterilisation (IUSS) and unverified sterility.

Why This Matters

Sterilisation failure is a silent contamination pathway. Unlike a dropped instrument or a glove breach, compromised sterility is not visible at the time it occurs. If instruments are assumed sterile without verified indicators, or if implant pack integrity is not confirmed before opening, the contamination event happens before the case begins. IUSS used as a routine workaround for inadequate inventory is a documented risk factor for surgical site infection — it bypasses the verification steps that exist to catch sterilisation failures.

Critical Control Points

• All sterilisation indicators verified before the case is cleared to proceed

• IUSS used only for genuine emergencies — never as a workaround for inventory gaps

• Implant pack integrity confirmed visually before opening

• Any failed indicator or damaged pack treated as non-sterile — no exceptions

Readiness Status

Mark each item Pass or Fail. Any Fail blocks the case until resolved.

Step-by-Step Protocol

1. 1

   Scrub technician confirms all instrument trays are present and assigned to this case.

2. 2

   Inspect all sterilisation indicators — chemical and biological. Any failed indicator means the tray is non-sterile. Do not proceed with that tray.

3. 3

   Confirm no IUSS is planned for routine inventory gaps. If IUSS is required, verify it is a genuine emergency and document the reason.

4. 4

   Confirm all implant packs for this case are present and unopened.

5. 5

   Inspect each implant pack visually: seals intact, no tears, no moisture exposure, expiry date valid.

6. 6

   Verify sterilisation indicators on implant packaging.

7. 7

   Surgeon and scrub technician confirm readiness aloud at the pre-case briefing. Any unresolved Fail is addressed before the patient enters the OR.

Key Pitfalls

• Assuming indicators have been checked because the tray was prepared — check them yourself, at the time of use.

• Opening a pack with a compromised seal and proceeding under time pressure.

• Using IUSS habitually to compensate for understocked instrument sets — this normalises a known infection risk.

• Not confirming implant pack integrity until the scrub technician opens them at the field — too late for safe substitution.
