Par Levels, FIFO Rotation, and Expiration Management

Why Inventory Management Matters in Sterile Processing

Every sterile package that reaches a surgical field or patient-care area must be safe, intact, and within its usable life. When inventory is poorly managed, staff may use expired items, run out of critical supplies mid-procedure, or miss a product recall. All three scenarios put patients at risk. As a Sterile Processing Technician, your responsibility is to keep the right quantity of the right items available — and to remove anything that should not be used.

Par Levels: Keeping Enough on Hand Without Overstocking

A par level is the minimum quantity of a supply item that must be on hand at all times. When stock falls to the par level, a reorder is triggered. Setting par levels correctly prevents both stockouts and excessive inventory that ties up storage space or expires on the shelf.

To set a par level, you need three numbers:

• Daily usage rate — how many units are used on an average day.
• Lead time — how many days pass between placing an order and receiving it.
• Safety stock — extra units kept as a buffer against unexpected demand or delayed delivery.

The formulas are straightforward:

> Reorder Point = (Daily Usage × Lead Time) + Safety Stock

> Par Level = Reorder Point + Safety Stock

Some facilities define par level as equal to the reorder point plus one order cycle's worth of stock; always follow your department's written policy. When calculating, round up to the next whole unit — you cannot use a fraction of a sterile package.

Document every par-level decision. Write down your assumptions, especially if daily usage varies (for example, higher on weekdays than weekends). A written assumption is reviewable; a mental one is not.

FIFO Rotation: First In, First Out

FIFO stands for First In, First Out. Newer stock is placed behind older stock so that older items are always picked first. This principle prevents items from sitting at the back of a shelf until they expire while newer stock is used in front of them.

To rotate stock correctly:

1. Before placing new deliveries, pull existing stock forward or remove it temporarily.

2. Place newly received items at the back of the shelf (or bottom of a stack).

3. Return existing stock in front of (or on top of) the new items.

4. Verify that expiration dates increase from front to back.

Handle packages gently during rotation. Dropping, crushing, or compressing a sterile package can compromise the seal. Inspect each package as you handle it: check for seal integrity, tears, moisture, and visible contamination. Any package with a compromised barrier is considered non-sterile regardless of its expiration date — pull it and document it.

Expiration Date and Event-Related Sterility

Sterile packages may carry a date-related expiration (a printed date after which the item must not be used) or be managed under an event-related sterility policy. Under event-related sterility, a package is considered sterile until an event — such as a torn seal, wet wrapper, or fall — compromises the barrier, rather than until a calendar date passes. Many facilities use both systems depending on the item and packaging type. Know your facility's policy.

Items approaching expiration need monitoring. A common practice is to flag items within 30 days of expiration for priority use or return. Items that have already expired must be pulled immediately, logged, and quarantined so they cannot re-enter circulation.

Never return an expired item to active stock. Place it in a clearly labeled quarantine area and follow your department's disposal or return-to-vendor procedure.

Product Recalls

Manufacturers and the FDA issue recalls when a product is found to be defective, contaminated, or mislabeled. Recalls are identified by lot number, sometimes combined with a catalog number or expiration date range. When a recall is announced:

1. Obtain the exact lot number(s) from the recall notice.

2. Search all storage areas — shelves, case carts, and any items already picked but not yet used.

3. Remove every matching item and place it in a labeled quarantine area — do not discard until instructed by your supervisor, because items may need to be returned to the manufacturer.

4. Complete a recall documentation form recording: the product name, lot number, quantity removed, location found, date and time, and your name.

5. Notify the appropriate clinical staff (such as the charge nurse) so they are aware no recalled items will be available and can plan accordingly. Keep the notification factual and prompt.

Speed and accuracy are both critical in a recall. A missed lot-number match could mean a defective device reaches a patient.

Documentation: The Paper Trail That Protects Patients

Every pull — whether for expiration, damage, or recall — must be recorded in a pull log. The pull log typically captures: item name and catalog number, lot number, quantity pulled, reason for pull, destination (quarantine, return, discard), date/time, and technician's name. Incomplete logs create gaps that can hide systemic problems and expose the facility to liability.

Accurate documentation also supports traceability — the ability to track which items were used in which procedures for which patients. Traceability is a patient-safety requirement and is evaluated during accreditation surveys.

Safety Summary

• Always handle sterile packages with clean, dry hands or clean gloves.
• Inspect packaging integrity every time you touch a package.
• When in doubt about sterility, pull the item — sterility must be certain, not probable.
• Never use an expired item, even in an emergency, without explicit direction from a licensed practitioner and documentation of the decision.
• Report recall findings to your supervisor immediately; do not wait until the end of your shift.
