Case Carts, Off-Site Delivery and Vendor Items
- Explain how to assemble, transport, decontaminate, and maintain case carts and specialty carts safely.
- Describe the requirements for packaging, transporting, and protecting sterile and contaminated items during off-site delivery.
- Detail the procedures for receiving, inspecting, reprocessing, tracking, and returning loaner sets, consignment inventory, and medical implants.
Case Cart Systems and Distribution Methods
Case cart systems are designed to provide patient-specific surgical instruments and supplies for scheduled procedures. Sterile processing technicians assemble these carts using a doctor's preference card or pick sheet, which identifies the specific items required for that exact surgical procedure. By gathering everything ahead of time, technicians ensure the surgical team has what they need when the patient enters the operating room.
Different inventory models determine when and how items arrive. In a Just-in-Time distribution system, supplies are brought to user departments immediately prior to scheduled procedures. In contrast, stockless distribution systems rely on vendors delivering pre-picked, department-specific orders directly to the point of use. Non-stock items are not kept in central warehouse storage and are ordered only upon departmental requisition, while special-order items are acquired specifically for an individual patient or procedure.
When an unopened sterile item returns to the sterile processing department on a clean case cart, it cannot simply be tossed back onto a shelf. Technicians must carefully inspect the packaging for any damage and verify that proper storage conditions and facility return criteria have been met before restocking it. This step safeguards patients from compromised packaging that might have encountered environmental hazards.
Proper loading prevents damage and workplace injury. When loading a case cart, technicians must place heavier instrument sets on the lower shelves. This keeps the cart's center of gravity low to prevent tipping and avoids crushing or damaging lighter items stored above.
| Distribution Model | Defining Feature | Primary Storage Location |
|---|---|---|
| Just-in-Time Distribution | Supplies delivered to user departments immediately prior to scheduled procedures | Central facility storage until needed |
| Stockless Distribution | Vendors deliver pre-picked, department-specific orders directly to point of use | Vendor facility until point-of-use delivery |
| Non-Stock Requisition | Supplies not routinely warehoused in central inventory; ordered only upon departmental request | Ordered directly from supplier as requested |
Common mistakes
- Assuming vendor-delivered loaner trays are clean and sterile upon delivery, skipping intake inspection and facility reprocessing.
- Relying solely on an intact tamper-evident seal to confirm a crash cart is ready for clinical use without verifying internal supplies or expiration dates.
- Loading sterile supplies onto a freshly washed case cart that is still damp, which risks packaging damage and microbial wicking.
- Prematurely releasing an implant load without a negative biological indicator result or documented emergency authorization from the surgeon or designated authority.
Key points
- Case carts supply patient-specific items based on preference cards; heavy sets must be placed on bottom shelves, and clean carts must be completely dry before loading.
- Soiled case carts must travel closed to decontamination, using designated soiled routes when available; carts are then cleaned and disinfected by a method permitted by the manufacturers' instructions and facility policy.
- Off-site transport must protect devices from environmental damage and keep clean and soiled goods physically separated; use climate control when needed to maintain required conditions, and package and label contaminated items under applicable transport rules, using leakproof containers and puncture resistance where needed.
- Tamper-evident seals indicate if emergency carts have been opened, but technicians must verify supply expiration dates within their scope, leaving medications to pharmacy or clinical staff.
- Loaner instruments must be logged upon receipt, checked against inventory lists, disassembled as directed, kept within applicable validated set-weight limits, and fully reprocessed before surgery.
- Sterilization loads containing medical implants require a biological indicator and a Type 5 integrating indicator (for steam), quarantine until BI results are documented negative (unless emergency release is authorized), and full decontamination before return to vendors.
