Nearly 500 hospitals track shortage-affected segments via RFID

When a drug goes short, most hospital pharmacy teams check the automated dispensing cabinet first. Those teams manage inventory across central pharmacies, operating rooms, infusion centers, clinics and satellite locations, and the cabinet view has been missing a meaningful share of the total medication supply: everything tracked with RFID.

Sean Gilman takes up that gap in a November 4 editorial in RXinsider. The scale is what stands out. According to Bluesight, nearly 500 hospitals already track shortage-affected medication segments in their RFID systems, almost 4,000 segments in total, and manage them with temporary PAR levels and acceptable alternatives.

So the data exists. What matters to a director of pharmacy or a health-system supply chain lead is whether it shows up in the number they use to decide on an emergency order.

Where the uncounted stock sits

Hospital pharmacies hold medication across central pharmacies, ORs, infusion centers, clinics and satellite locations, Gilman writes, and the cabinet data and the RFID data have historically lived in separate systems. In a shortage, someone has to reconcile them by hand, and that cross-referencing can eat hours of skilled pharmacy time. Skipping it has a cost too. A count that misses RFID stock makes supply look thinner than it is, which the editorial ties to a false sense of urgency and wasteful emergency purchases.

Taken together, the figures suggest the RFID systems hospitals built for kit and tray management have become a second inventory that the shortage workflow hasn't been reading. Gilman argues RFID has moved past kits and trays into active shortage response across the pharmacy enterprise. The Bluesight segment count backs him up: hospitals are already setting shortage rules inside these systems.

From tray accuracy to days on hand

Readers extract unique identifiers from tags by emitting radio waves, without needing a line of sight, and multiple tags can be read at the same time. That could make checking a full tray much faster than scanning items one at a time.

Those are counting wins. Shortage response asks the data for something harder: how fast a drug is moving and how much buffer is left. Gilman's case is that when RFID unit totals, location counts and usage patterns flow in next to cabinet data, the usage rate reflects consumption across the whole system instead of cabinet activity alone. During a shortage, a count that stops at the dispensing cabinet can get both halves of the days-on-hand math wrong: how much stock is on hand and how fast it is being used.

The gain is largest where stock is spread out. For a health system whose RFID footprint is concentrated in those settings, each new deployment adds stock that shortage planners can see. A system that uses RFID only for a handful of crash-cart kits would likely see a smaller change.

Tags, standards and who can read them

Intelliguard, an RFID medication management company, notes that hospitals can partner with drug manufacturers like Fresenius Kabi and Cencora to purchase pre-tagged or source-tagged medications. That approaches Gilman's argument from the analytics side. For procurement teams, source tagging could decide how much of the inventory ends up visible without pharmacy staff tagging it by hand.

Tag frequency is another spec-sheet choice. TSC argues high-frequency RFID suits pharmacy shelves better than the UHF, or RAIN, tags common in logistics: short-range HF reads hold up around metal racks, liquid-filled vials and foil-backed packs, and pick up only the item in front of the reader. Those claims come from a vendor.

Where a merged feed still falls short

The strongest caution comes from a narrative review in the International Journal of Scientific Research and Technology by independent researcher Samiyullaha Sayyed. It asks why automated hospital pharmacies still find gaps between perpetual inventory and physical stock, and two of its five causes bear directly on this idea. Systems are often connected at the interface level but not the transaction level, so data from cabinets, ERP, the EHR and wholesalers arrives late and in pieces. And human handling, including borrowing, waste, returns and multi-step dispensing, happens where automation can't fully see it, a limit the review says also applies to some RFID deployments.

In the case evidence Sayyed reviews, RFID and dispensing-cabinet deployments improved accuracy and time-to-restock but did not eliminate discrepancies. Lasting gains, the review argues, need transaction-level data governance, verification at every physical handoff and clear ownership of exceptions. That doesn't undercut Gilman's case. It sets the bar: a merged RFID and cabinet count is only as good as the handoffs feeding both.

For operators, one number to watch could be the share of facilities planning to implement RFID within the next 12 months. Each rollout that lands in an infusion center or surgery center adds stock to the shortage picture, but only if the shortage workflow reads it.
