FIFO (First In, First Out) in healthcare: A critical patient safety imperative

How can this logistical constraint be transformed into a smooth process within hospital pharmacies (PUI) and care units? An analysis of a vital methodology.

Beyond logistics: The clinical stakes of FIFO

In a conventional warehouse, an expired product is a financial loss. In a hospital, it represents a **clinical risk**. The FIFO (First In, First Out) method ensures that items with the nearest expiration date are used first.

This strict approach addresses three major challenges in healthcare:

1. Medication-related harm: Prevent the administration of drugs whose efficacy is compromised or whose toxicity may increase due to expiration.
2. Management of implantable medical devices (IMDs): These high-cost items (prostheses, pacemakers) have strict sterility dates. Poor rotation can result in significant financial losses for the facility.
3. Immediate availability: In urgent situations, caregivers must not waste time checking multiple boxes to find the correct one. The first item picked must be the right one.

Storage architecture: ISO 600×400 standard supporting flow

Implementing FIFO relies not only on staff discipline but also on the **ergonomics of storage furniture**. The hospital standard ISO 600×400 is designed to facilitate stock rotation.

The "Full/Empty" system and Kanban

FIFO is often implemented using the "double-bin" or Kanban method in service cabinets.

• The principle: Two identical bins are placed one behind the other (or side by side). Items are picked from the first bin (oldest batch). Once empty, the tag is flipped (signal to reorder), and the second bin (newer batch) becomes accessible.
• Required equipment: Modular shelving allowing ISO baskets to be inserted with stops, ensuring the reserve bin is always positioned behind the active bin.

Through-flow Storage for Hospital Pharmacies (SHP)

For hospital pharmacies handling large volumes, static shelving without crossbars supports FIFO.

• It separates flows: logistics staff stock shelves from the rear (service corridor), while pharmacy technicians pick from the front.
• This natural “forward flow” enforces the use of the oldest stock without complex handling.

Gravity shelving for infusions and solutes

Boxes of IV bags or nutrition packs are heavy and hard to handle. Using dynamic roller rails allows boxes to slide forward. The first box placed is mechanically the first available, reducing musculoskeletal disorders (MSDs) caused by lifting items from the back of shelves.

Best practices to ensure reliable FIFO

Equipment must be supported by a rigorous organization:

1. Visual zoning: Clearly label locations. Misplacing a product (e.g., placing product B in the slot for product A) nullifies the benefits of FIFO.
2. Visible expiration dates: Upon receipt and unpacking, ensure the expiration date remains visible on primary or secondary packaging.
3. Returns management: Returned items (unused medications) must be reintegrated with care, ensuring they are not placed in front of older batches.

Securing the medication circuit

Implementing strict FIFO management is a prerequisite for healthcare facility certification. It requires shifting from a “mass storage” mindset to a **just-in-time flow** logic.
