Cath Lab Consumable and Implant Tracking at Point of Use

Most Indian cath labs run substantially on consignment. Stents, balloons, and specialised devices sit in the lab in the supplier's ownership, and title passes when the item is used. This is commercially sensible, because a lab cannot fund the working capital to hold every size of every platform, and clinically necessary, because you cannot predict which length you need until the wire is across the lesion.

It also creates a records problem that plain inventory software handles badly. The lab is physically holding stock that does not sit on its balance sheet, and the same shelf may hold owned and consigned items side by side. Your system needs an ownership attribute per item, a consumption event that converts a consigned item into a purchase, and a periodic statement reconciled with each supplier. Without that, month-end becomes a negotiation with the company representative rather than a reconciliation.

The trade-off nobody mentions in the contract is the representative in the room. Company representatives replenish consignment trays, and in many labs they also know what was used better than the hospital record does. That is a governance weakness, not a convenience. Replenishment should follow the hospital's consumption record, not the other way around, and the reconciliation should be the hospital telling the supplier what was used rather than accepting the supplier's list.

The practical objection to point-of-use scanning is that the person opening the packet is scrubbed. The workable answer is that the circulating technician scans, not the scrubbed operator. The item is presented, the outer packet is opened, the circulator scans the barcode on the outer wrapper before the inner is passed to the field, and the scan goes to the procedure record with a timestamp. This is a two-second action and it happens at the natural moment the packet is already in someone's hand.

Placement of the reader decides whether this survives contact with a busy list. A reader on the control room desk means the circulator walks away from the table, which they will not do during a difficult case. A wireless reader mounted where the packets are opened, or a tablet on the equipment trolley, means the scan happens where the work happens. Test this with the technicians before purchase and accept their judgement about placement; it is the whole difference between adoption and a device that sits in a drawer.

Barcode quality is the practical limiter. Not every consumable sold in India carries a scannable identifier that your system recognises, and some carry a supplier's internal code rather than a standard one. Build a mapping table and a manual fallback that captures the same fields by typing, and monitor how often the fallback is used. That percentage is your real coverage figure, and it is usually much lower than the vendor demonstration suggested.

A scan that only decrements inventory has done half the job. The same event should write the device identifier, lot, and expiry into the procedure record against the patient, at the position in the procedure where it was used. For a coronary case that means the device is tied to the vessel and the lesion treated, which is what a cardiologist actually needs when the patient returns in three years with in-stent restenosis and someone has to know exactly what is in that artery.

This linkage is also the only thing that makes a recall answerable. When a manufacturer or the regulator issues a field safety notice for a lot, the question is which patients received devices from that lot, and it must be answerable in minutes. A system that can produce that list from a query has a functioning traceability capability. A system that requires someone to open two years of procedure files has, in practice, no capability at all.

Carry the same identifiers into the documents the patient leaves with. An implant card or a discharge summary that names the device, the lot, the date, the operator, and the vessel treated is useful to every clinician who sees that patient afterwards, and it costs nothing once the data is structured. HealUDoc can carry the device record on the encounter so the implant details print into the discharge summary rather than being retyped by a records clerk from the operator's notes.

Reconciliation is a daily discipline, not a monthly count. At the end of each list, the system should present what it believes was consumed, and the technician confirms or corrects it against what physically left the shelves. Doing this while the day is still fresh takes a few minutes. Doing it at month end takes a day and produces guesses, because nobody remembers whether the second balloon on Tuesday's fourth case was used or discarded.

Three categories cause almost all the discrepancies and each needs its own handling. Opened-not-used items must be recorded as consumed with a wastage reason, because they are gone whether or not they entered a patient. Items taken from the emergency trolley during an unplanned case are often never recorded at all, so the trolley needs its own replenishment check. And items borrowed between labs or between the cath lab and theatre disappear entirely unless transfers are transactions.

Watch the trend of the discrepancy rate rather than any single day. A lab whose daily variance is consistently small has a working process; one whose variance is small on quiet days and large on busy days has a process that fails exactly when accuracy matters. That second pattern usually points at reader placement or staffing during the afternoon list, and it is fixable once you can see it.

Charge leakage in a cath lab is the mirror image of stock leakage and it has the same root cause. If the billing entry is made by a clerk reading the operator's handwritten notes, the expensive items get captured and the cheap ones do not. A dozen uncaptured wires, sheaths, and inflation devices per list is not a rounding error over a year. When the consumption event and the charge event are the same event, the leakage largely disappears without anybody being asked to try harder.

The rule to establish is that the scan creates a charge line in a draft state, and the case cannot be closed until every line is either confirmed, marked as non-chargeable with a reason, or written off with an authorisation. Non-chargeable is a legitimate outcome, particularly under package arrangements where consumables are bundled into the package rate, so the system must handle it as a normal path rather than as an exception that people learn to avoid by not scanning.

Be careful about where the control sits. Billing staff should not be able to add a device charge that has no corresponding consumption event, and clinical staff should not be blocked from proceeding because a rate is missing. Separate the clinical record of use from the pricing decision, let the case close on the clinical record, and let the finance team resolve pricing afterwards. Labs that conflate the two end up with clinicians who avoid the system during difficult cases, which defeats the entire purpose.

The recurring cost of this is not the software. It is the daily reconciliation, the mapping table maintenance as suppliers change packaging, the barcode fallback handling, and the discipline of transfer transactions between locations. Somebody has to own that, and in most labs the honest answer is a senior technician with protected time rather than a materials clerk sitting in the store. Allocating that time explicitly is the difference between a system that stays accurate and one that degrades quietly over eight months.

The predictable failure modes are worth planning for. Emergency and out-of-hours cases where the trained technician is not present. Devices used during a primary angioplasty at two in the morning, when nobody is going to stop to scan and nor should they. Trays replenished by a supplier representative outside the system. Each needs a defined catch-up path: record what was used at the earliest safe moment, mark it as retrospective, and monitor how large that retrospective share becomes.

One thing not to skip is the radiation and equipment context this all sits inside. The cath lab already maintains AERB-related records for the installation and personnel monitoring, and NABH assessment will look at implant traceability alongside them. Keeping consumable records in the same operational rhythm as those obligations, reviewed at the same monthly meeting, is what stops point-of-use tracking from becoming a project that succeeds for a quarter and then is quietly abandoned.
