SPD Sterile Storage and Transport 2 — Questions and Answers
Question 1: What environmental monitoring should be performed in sterile storage areas?
- No monitoring is required
- Continuous temperature and humidity monitoring with documented readings and defined action limits (Correct answer)
- Only weekly visual inspections
- Monthly air quality testing only
Correct answer: Continuous temperature and humidity monitoring with documented readings and defined action limits
Continuous environmental monitoring ensures storage conditions remain within parameters that support sterile packaging integrity.
AAMI ST79 requires: temperature at or below 75°F (24°C), humidity between 30-60% RH, adequate air exchanges, calibrated recording instruments, data loggers with alarm capabilities, regular documentation and trend analysis, and defined action plans for excursions. Many facilities use automated monitoring systems with real-time alerts.
Question 2: What is the correct procedure for transporting sterile items between buildings or to off-site locations?
- Place items in regular boxes and transport in any vehicle
- Use sealed, protective transport containers and vehicles with climate control to maintain packaging integrity (Correct answer)
- Transport is unnecessary
- Any employee can transport sterile items without special procedures
Correct answer: Use sealed, protective transport containers and vehicles with climate control to maintain packaging integrity
Inter-facility transport requires sealed protective containers and climate-controlled vehicles to protect sterile items from environmental extremes and physical damage.
Inter-facility transport requires: sealed rigid transport containers, climate-controlled vehicles, minimized weather exposure during loading/unloading, documentation tracking departure and arrival times, inspection upon arrival for packaging integrity, and clean transport containers between uses.
Question 3: How should recalled sterile items be managed in the storage area?
- Leave them on the shelf until someone collects them
- Immediately quarantine recalled items in a clearly marked segregation area and document the recall process (Correct answer)
- Return them to the decontamination area
- Discard them in regular waste
Correct answer: Immediately quarantine recalled items in a clearly marked segregation area and document the recall process
Recalled items must be immediately identified, physically separated from available inventory, and documented to prevent inadvertent use.
Recalled items must be: immediately identified using load records, physically removed to a quarantine area with 'DO NOT USE' signage, documented with identification and recall reason, cross-referenced with distribution records to retrieve items sent to clinical areas, held until disposition is determined, and the entire recall process should be practiced through drills.
Question 4: What is the significance of positive air pressure in sterile storage areas?
- It helps cool the room
- Positive pressure prevents unfiltered air from flowing into the storage area, reducing airborne contamination risk (Correct answer)
- Positive pressure is only needed in operating rooms
- Air pressure has no effect on sterile storage
Correct answer: Positive pressure prevents unfiltered air from flowing into the storage area, reducing airborne contamination risk
Positive air pressure ensures that clean filtered air flows out when doors open rather than allowing contaminated corridor air to flow in.
Positive pressure means air flows outward through any openings, preventing unfiltered corridor air from entering. Requirements include: minimum 2-4 Pascals positive pressure, HEPA or high-efficiency filtration, pressure monitoring with alarming, and vestibule design to reduce pressure loss. This follows the SPD airflow hierarchy: sterile storage (most positive) to decontamination (most negative).
Question 5: How should implantable devices be managed differently in sterile storage compared to standard instruments?
- Implants are stored the same as all other items
- Implants require separate tracking, biological indicator verification before release, and often dedicated secure storage (Correct answer)
- Implants do not need to be stored in sterile storage
- Implants only need visual inspection before use
Correct answer: Implants require separate tracking, biological indicator verification before release, and often dedicated secure storage
Implantable devices require enhanced tracking, mandatory BI verification before release, and often secure storage due to higher infection risk.
Implant requirements include: BI quarantine until negative result (rapid-read BIs enable faster release), enhanced individual tracking linked to patient records, often dedicated locked or restricted-access storage, lot/serial tracking for post-market surveillance, and specific temperature requirements for some biologics. Joint Commission and CMS specifically address implant sterilization during surveys.
Question 6: What should be done when the sterile storage area experiences a power outage affecting HVAC systems?
- Nothing — power outages do not affect sterile items
- Document the duration and conditions, assess items for compromised integrity based on temperature/humidity excursions, and implement contingency protocols (Correct answer)
- Immediately discard all stored items
- Wait until power returns without assessment
Correct answer: Document the duration and conditions, assess items for compromised integrity based on temperature/humidity excursions, and implement contingency protocols
Power outages disrupting environmental controls must be documented and assessed for their impact on sterile storage conditions.
Response includes: record outage time, close doors to maintain conditions, restrict access, monitor temperature and humidity with battery-operated devices, after restoration assess whether conditions exceeded limits, evaluate items for moisture or condensation, and reprocess compromised items. Prevention includes emergency power for HVAC and documented contingency plans.
