CIS Quality Assurance Systems Questions and Answers 2 — Questions and Answers
Question 1: What is the primary purpose of biological indicators in sterilization quality assurance?
- To measure the temperature inside the sterilizer
- To verify that sterilization conditions were sufficient to kill highly resistant bacterial spores (Correct answer)
- To check chemical sterilant concentration
- To confirm instruments were cleaned before sterilization
Correct answer: To verify that sterilization conditions were sufficient to kill highly resistant bacterial spores
Biological indicators contain highly resistant bacterial spores and serve as the gold standard for verifying sterilization lethality.
BIs are the gold standard because they directly challenge process lethality with live organisms. For steam, Geobacillus stearothermophilus spores are used. After exposure, BIs are incubated to determine if spores survived. AAMI recommends BI testing at least weekly and with every implantable load.
Question 2: What does a positive biological indicator result require the department to do?
- Simply document and continue operations
- Immediately recall all items from the suspect load, quarantine remaining loads, and investigate (Correct answer)
- Replace the BI brand
- Clean the sterilizer and run another cycle
Correct answer: Immediately recall all items from the suspect load, quarantine remaining loads, and investigate
A positive BI triggers immediate recall of affected items, quarantine of subsequent loads, root cause investigation, and retesting before returning the sterilizer to service.
Response protocol: remove sterilizer from service, recall all items from the affected load, quarantine loads since the last negative BI, investigate root causes, perform three consecutive negative empty cycles with BIs, then return to service. Document the entire event.
Question 3: What is the purpose of documenting sterilizer cycle printouts?
- To satisfy insurance requirements only
- To provide a permanent record of sterilization parameters for verification, traceability, and compliance (Correct answer)
- To calculate energy consumption
- To determine when to replace the sterilizer
Correct answer: To provide a permanent record of sterilization parameters for verification, traceability, and compliance
Cycle printouts provide objective records of time, temperature, and pressure parameters, enabling verification and providing traceability for regulatory purposes.
Printouts serve real-time verification, traceability for investigations, trend analysis for developing equipment issues, regulatory compliance, and legal protection. All printouts must be reviewed, signed, and retained per facility policy.
Question 4: How often should biological indicator testing be performed for standard loads?
- Only during annual maintenance
- At least weekly and with every load containing implantable devices (Correct answer)
- Every six months
- Only when failure is suspected
Correct answer: At least weekly and with every load containing implantable devices
AAMI recommends BI testing at least weekly for routine loads and with every implant load, as implants pose the highest infection risk.
BI testing follows a risk-based approach: every implant load (ideally quarantined until BI result known), at least weekly for routine loads, and after installation, malfunction, major repair, or process change. Many facilities exceed minimums by testing daily.
Question 5: What is a corrective action plan in sterile processing quality assurance?
- A plan to purchase new equipment
- A documented response identifying root cause of a quality deviation and steps to prevent recurrence (Correct answer)
- A schedule for routine maintenance
- A training manual for new employees
Correct answer: A documented response identifying root cause of a quality deviation and steps to prevent recurrence
A corrective action plan formally identifies root cause, details immediate corrective steps, defines preventive measures, and assigns responsibility and timelines.
Corrective action plans follow a structured approach: problem identification, immediate containment, root cause analysis, corrective action, preventive action, verification of effectiveness, and complete documentation.
Question 6: What role does competency testing play in sterile processing quality assurance?
- Only needed for new employees
- Ongoing verification that staff can correctly perform critical processes, typically annually (Correct answer)
- Replaces biological indicator testing
- Optional for experienced staff
Correct answer: Ongoing verification that staff can correctly perform critical processes, typically annually
Competency testing provides documented verification that all staff can correctly perform duties, conducted during orientation, annually, and when procedures change.
Human error accounts for a significant percentage of reprocessing failures. Competency programs include initial assessment, annual verification, reassessment when procedures change, and targeted assessment when quality issues arise. Documentation is required by accrediting bodies.
