A hospital procurement manager answers questions on the ConvaTec product catalog, ConvaTec Stomahesive paste uses, defibrillator AED buying, ICU monitor TCO, and what medical ultrasound really costs.

I'm a procurement manager for a mid-sized health system. I've managed supplies for over six years, and I track every order in our purchasing system. Maybe I've processed around 180 orders for medical products, maybe slightly fewer, I'd have to check. This FAQ is the one I wish I'd been given when I started.

1. What actually matters when you look at the ConvaTec product catalog?

The first thing I tell anyone is not to search the ConvaTec product catalog by brand name if you're new. Search by care setting. The catalog is grouped around wound, ostomy, continence, and infusion care. If you're a procurement person, that layout stops you from comparing a skin barrier to a catheter by mistake.

The catalog includes products like Stomahesive, Aquacel, Versiva, Conveen, and GentleCath, but the exact list changes. The version I last pulled from convatec.com in January 2025 is mainly organized by condition and category, not by a single alphabetical product list. That sounds small, but it means you need to know which formulary category you're pricing before you request a quote.

Let me rephrase: when a clinician asks for "the paste," they usually mean Stomahesive paste. When they ask for "the barrier," they might mean a moldable skin barrier. If you put the wrong product category on the PO, you will buy a $30 tube of paste when what they needed was a box of barriers. At least, that's been my experience.

2. What are ConvaTec Stomahesive paste uses?

Stomahesive paste is a protective paste designed to fill skin folds, creases, and gaps around a stoma. It does not "adhere" like a glue; it fills space so the pouch barrier sits flush against the skin. In practice, that means the paste helps prevent effluent from leaking under the wafer and damaging peristomal skin.

I've also seen it used around wounds and fistulas on the abdominal wall, but the official product use is for stomas. If you're writing a bid spec, call it "stomahesive paste, skin-protective filler for stoma care," and check whether the clinician wants a 60g tube or a smaller unit. In our records, the tubes are often reordered as single-item replacements, which means the per-use cost is what you need to track, not just the tube price.

One thing that surprised me in our spend analysis: paste and powder were grouped together in the legacy purchasing system. They're not interchangeable. Paste fills crevices; powder dries weepy skin. Both are cheap individually, but if your catalog loads them as alternates, you will end up with expired cylinders while the other stock-outs. Maybe that's just my sample, but it has happened twice in our system.

3. How do you compare costs for ConvaTec products?

For disposables, I calculate total cost of ownership per patient day, not per unit. The unit price for a skin barrier is important, but the bigger cost is clinical labor and product failure. A cheaper barrier that needs reapplication because it doesn't conform as well costs you nursing time, waste, and patient discomfort. That is not an easy number to get from a quote, but it shows up in your staff hours and supplies budget by the end of the quarter.

I compare quotes using a simple table: item unit cost, units per order, ordering frequency, shelf life, and the number of SKUs in the same family that the warehouse has to hold. I built that after a vendor failure in March 2023 where "same product, new packaging" caused a week of confusion on the floor. The order cost was the same; the hidden retraining and double-shipping costs were not.

In my opinion, you should also ask the sales rep for the full list of related accessories. For ostomy care, that might include paste, powder, barrier rings, and adhesive remover wipes. If you only put the first item on the RFQ, the total cost of ownership is incomplete.

4. What should I budget for when buying a defibrillator AED?

The automated external defibrillator (AED) purchase is usually the easiest part of the budget because the device quote gets all the attention. The total cost of ownership includes the battery, electrode pads, carrying case, signage if you're installing it in a public area, and the training supplies you'll use to make sure staff actually know how to respond. The American Heart Association's 2020 CPR & ECC guidelines still call early defibrillation a critical link in the chain of survival, so the cost question isn't "should we buy one?" but "how many and where?"

What I've learned from tracking our AED program: pads and batteries expire. They just do. If the device is in a cabinet and the maintenance log is not checked, you'll find out during an inspection. That is why I ask for the manufacturer's recommended replacement schedule in writing before I sign. I also ask about multi-year electrode pad compatibility. A device that took a different pad, discontinued it two years later, requires a whole new set of consumables—or worse, a new device.

Had to make a call once with 24 hours to go on a grant deadline. Normally I'd run a full RFQ, but there was no time; I bought the same brand as the rest of the fleet because the rep gave me a firm price on pads for the next five years. In hindsight, I should have asked the hospital biomed team first. The "gift" of consolidating training was real, but it unnecessarily limited the choices. At least, that's been my experience.

5. What does an ICU monitor really cost over time?

When I look at an ICU monitor, I don't ask "how much is the screen?" I ask what the full package includes: the parameter modules, the mounting arm, the central station software, the network cables, the installation, the training, and the service agreement. The monitor is the visible part. The ecosystem around it is where the budget goes.

If the monitor uses proprietary disposable sensors, you need to ask what those cost, because pulse oximetry probes and blood pressure cuffs are replaced constantly. For example, a vendor might quote a lower monitor price to win the bid and make revenue back on the sensors and service contract. That's not necessarily unethical, but it will distort your budget if you're only comparing list prices. Put another way: the lowest monitor bid can be the highest system bid.

I went back and forth for two weeks on an ICU monitor selection for a 12-bed unit. The cheaper monitor had a better hardware price but a shorter warranty. The other one cost about 9% more per unit and included an extra year of service and a loaner guarantee. I finally chose the second one. Downtime in an ICU is not something I want to own. Also, ask for IEC 60601-1 compliance documentation. It's the baseline safety standard for medical electrical equipment, and if a quote doesn't include it, someone hasn't done their homework.

6. What is medical ultrasound?

Medical ultrasound is a diagnostic imaging method that uses high-frequency sound waves—usually in the 2 to 15 MHz range—to create real-time images of soft tissues and blood flow. Unlike X-rays or CT scans, it does not use ionizing radiation, which is one reason it's used for obstetric imaging, musculoskeletal exams, cardiac studies, and bedside assessments.

For procurement, the important part is that the transducer (probe) determines what the system can do. A curved array probe is used for abdominal exams. A linear probe is used for vascular and musculoskeletal work. A phased array is common for cardiac. You can buy the same ultrasound engine with very different probe sets, and the probe configuration is often the biggest cost driver. That's easy to miss if you're comparing only the main unit.

Also, ultrasound probes are fragile. They get dropped, the ceramic elements crack, and a repair can cost a meaningful percentage of a new probe. I now include a spare probe plan and a service contract in every ultrasound RFQ. And because ultrasound is used in different departments—radiology, emergency, cardiology—one "what is medical ultrasound" answer does not give you a clean spec. You need to write the spec by use case, not by device name.

7. Why did I stop making buying decisions based on unit price alone?

Here's the trigger event that changed my approach. In February 2023, we ordered what looked like the same wound dressing SKU we'd been buying for two years. The quote was 11% lower than the incumbent vendor. Then the shipment came with different packaging, a different code, and no instructions in English. It took our clinical team three days to realize it was not an identical substitute. The "savings" disappeared in nursing verification time, returns, and expedited shipping for the real product.

I did not suddenly become a brand loyalist—that isn't in my job description. But I stopped evaluating products by price alone. I built a minimal TCO calculator with columns for unit price, consumables, training, service, compliance, and risk. I can't claim it captures everything; my experience consists of roughly 180 purchase orders across two midsized hospitals, mostly in the U.S. If you're buying through a national GPO or in a regulated market like the EU, your line items will look different.

The point isn't to fear every cheap alternative. The point is to make the trade-offs explicit. The next time someone asks me which AED, monitor, ultrasound system, or wound care line to buy, I don't tell them which has the lowest sticker price. I ask, "What else has to be true to make that price work?" And then we run the numbers together.
