The next shipment decision in a growing ASC network should not begin with a phone call to the rep.
It should begin with a shared answer to four questions: Which tray is actually ready? Which site needs it first? How long will it take to move it? What happens if the planned route fails?
That sounds like basic logistics. In practice, many device teams still route surgical trays through a mixture of spreadsheets, standing habits, text messages, carrier cutoffs, and local memory. The system works until a network adds another ASC, a hospital keeps a loaner set in sterile processing, or a field representative redirects inventory to protect a case. Then a route that looked efficient on paper becomes an emergency shipment, a duplicate kit, or a morning spent searching for an asset that was never truly available.
The outpatient market is making this problem more visible. The number of ASCs in the United States grew by more than 2% per year on average from 2019 through 2024, while ASC surgical procedure volume per fee-for-service beneficiary increased 3.5% in 2024, according to reporting on the MedPAC data discussed by Becker's ASC. At the same time, more complex orthopedic and spine procedures are moving into outpatient settings. The result is a network with more destinations, tighter inventory, and less room for a tray to sit in the wrong place.
A route is not the same thing as a shipment
In a traditional warehouse model, routing is mostly a transportation question. Pick the order, choose the carrier, confirm delivery, and close the transaction.
Surgical trays do not behave like ordinary cartons. A tray may be in a distributor warehouse, at a 3PL, in a hospital receiving area, inside sterile processing, packed for a case, awaiting inspection, or returning from a procedure. Each location changes what can happen next. A set inside decontamination cannot be routed to tomorrow morning's ASC case in the same way as a set sitting clean and ready in a local warehouse.
This is where many operating teams make an understandable mistake. They treat location as the most important field because location is easy to ask for. Where is the tray? Where did the carrier deliver it? Which site has it on the spreadsheet?
But location without status creates false confidence. A tray can be at the right facility and still be unusable. It may be unprocessed, incomplete, assigned to a different case, or waiting for a documentation check. Conversely, a tray that appears to be away from the target site may be the best option if it is clean, complete, and moving on a reliable route.
A routing rule for surgical assets therefore needs to combine at least four conditions:
- Physical location: where the asset is now.
- Processing status: whether it is available for use, in decontamination, awaiting inspection, or otherwise unavailable.
- Case assignment: whether it is committed to a scheduled procedure and when that commitment matters.
- Movement priority: whether it should stay local, return to a shared pool, or move to the next site.
Without those distinctions, a 3PL can deliver on time and still fail the case. A distributor can show a healthy inventory balance and still trigger a duplicate shipment. A field team can know where a set was last seen without knowing whether anyone can use it.
ASC growth turns local habits into network risk
A single hospital can sometimes absorb a routing mistake. It may have backup trays, a larger sterile processing department, more storage, and enough institutional memory to locate an asset before the case is affected.
A smaller ASC usually has less slack. One orthopedic set may support a meaningful share of the day's schedule. The center may have limited storage, a compact sterile processing workflow, and no dedicated supply chain analyst reviewing every vendor movement. When a tray is delayed, the response often falls to an administrator, OR coordinator, sterile processing technician, or field representative who is already managing something else.
That is why network expansion changes the meaning of a late return. In a local operation, the set may be back by the next morning. In a distributed ASC network, that same return may be the missing link in a three-site sequence. The tray is not simply late. It has disrupted the planned circulation of inventory.
Industry attention is already moving in this direction. A 2026 overview from Becker's ASC described continued expansion of high-acuity procedures, larger ASC operators, and pressure from rising staffing and supply costs. Those pressures make routing discipline more important, not less. When margins are tight, the answer cannot be to place a duplicate kit at every site just in case. That protects one case by hiding the cost of poor circulation.
The better question is whether the network knows which assets are scarce, which are consistently underused, and which are spending too much time between sites. That requires movement data, not only an inventory count.
The 3PL handoff should change the plan, not end the visibility
Third-party logistics providers often sit at the exact point where a routing decision becomes operational. A 3PL may receive trays from a manufacturer, consolidate shipments, stage inventory for several facilities, arrange outbound transportation, and process returns. That creates leverage, but it also creates a dangerous handoff if the rest of the network cannot see what happened.
The handoff should answer more than “delivered.” It should establish whether the asset is at the expected site, whether the receiving team accepted it, and whether the tray's next state is known. If the destination cannot process the set in time, the network should be able to identify another viable route before the original shipment becomes a case delay.
This matters especially for loaner instrumentation. The AORN sample policy for loaned instruments describes receipt, inspection, recording, decontamination, and sterilization as part of the facility's responsibility. A delivery confirmation is therefore only the beginning of the operational chain. The tray still has to enter the local process, meet the facility's requirements, and become case-ready.
For distributors and manufacturers, the practical implication is straightforward: the routing system should not disappear when the asset crosses the hospital dock. Visibility needs to follow the tray through the warehouse, receiving area, sterile processing department, staging area, and return path. That is where an always-on asset view is more useful than a series of manual status updates. Teams can see whether a set is moving, sitting, assigned, or stuck, without asking every person in the chain to create another record.
The same view also changes the field representative's role. Instead of spending the morning proving where a tray went, the rep can focus on the exception: a set that missed a cutoff, a case whose required inventory is not ready, or a return that will affect the next site's schedule.
The rule should be simple enough to use under pressure
No network will route every tray through a perfect optimization model. The rule has to work when the schedule changes, when a case moves forward, or when a carrier misses a pickup.
A workable policy might look like this:
- Keep scarce, high-use sets close to the sites that use them most often, but verify that “close” means ready and not merely stored nearby.
- Route shared sets based on confirmed case demand and processing time, not on the last spreadsheet update.
- Escalate any asset whose location is known but whose processing status is not.
- Use movement history to identify recurring late returns and unnecessary duplicate inventory.
- Make the same asset record visible to the warehouse, 3PL, field team, hospital, and ASC when each group is responsible for a different handoff.
None of those rules eliminates judgment. They make judgment better informed. A live picture of trays, loan sets, and implant totes can show whether the network has a transportation problem, a processing bottleneck, a scheduling conflict, or an inventory policy that is creating avoidable cost.
The timely operational question for ASC networks is not whether they need more shipments. It is whether every shipment is compensating for something the network cannot see.
When a tray is routed by habit, the network pays for uncertainty through expediting, duplicate kits, idle inventory, and frantic calls. When it is routed by location, readiness, case demand, and movement history, the same inventory can serve more sites with less drama.
That is the difference between moving assets and managing a network.
