A purchasing coordinator turned her own $38,000 of medical equipment mistakes into a practical 7-step buying checklist—covering STERIS surgical tables, RESI tests, dental X-ray machines, dental implants, and incontinence products.

Who should use this checklist

I sign purchase orders for a regional health system. Not just the hospital side, but also an affiliated oral surgery clinic and, a mile away, a long-term care unit. Between 2019 and 2024, I made eight genuinely stupid buying mistakes. By my count, they cost roughly $38,000 in wasted budget—plus a stack of apologetic emails that don't show up in the spreadsheets.

This isn't a procurement-theory article. It's the checklist I run now before I buy anything that costs more than $500, or that clinical staff will rely on every day. The list works for items as big as a surgical table and as small as a box of test strips. It took me a few years and a few invoices to learn that the price tag is the least interesting number on the page.

The 7-step checklist

1. Identify the service path before you identify the vendor

In 2019—well, we actually took delivery in 2020, after construction delays—we bought two STERIS 3080 surgical tables for the new OR. I spent weeks comparing tabletop sizes, load capacities, and imaging compatibility. I never asked how the tables would be maintained once the warranty clock started.

A year later, one table developed a height-drift problem. Our biomedical team wanted to do the initial check in-house. That's when someone asked me, "Do we have access to the STERIS 3080 surgical table service manual?" We didn't, and I had not asked who could service the table or how an in-house PM program would get approved. It all worked out, but only after several phone calls and a delay nobody needed.

Now the first line on any capital quote says: service path. Who installs it? Who does the annual PM? If your own team handles repairs, what documentation and training do they need? Ask before signing, not after the table starts drifting.

2. Put required test products and consumables in the original quote

Every piece of reprocessing equipment has a small item that verifies the process. For us, one of those is the STERIS RESI test. I'm not going to pretend I knew what it did when I first saw it on a requisition; I knew only that our SPD lead wanted it in stock.

What I did next was the classic purchasing mistake: I found a cheaper test from a different supplier and assumed it was the same. It wasn't. The packaging looked close, but the product numbers and intended use were different. Fortunately, our sterile processing supervisor caught the substitution before we ran a single load. The real cost, though, was visible: the correct item had to be expedited, and the invoice for that expedite was higher than the amount I had "saved."

Now I ask three questions for any machine with a required consumable: What is the exact test or accessory? Is it brand-specific to the equipment? And what is the backup supply plan if it is backordered?

3. Compare the installed cost, not the quoted price

The dental x-ray machine story is the one I still feel. In 2022, our oral surgery clinic asked for a new digital dental x-ray machine. The quote was clean: $16,800, if I remember correctly. Actually, $16,800 was the price for the machine only. The final cost was closer to $23,000 once we added mounting, network cabling, a software license, lead apron replacement, and removal of the old unit. The surprise wasn't the machine's price tag. It was the list of things nobody quoted until after the PO was signed.

A dental x-ray machine is a good example of why we now write "installed cost" in the first column of every comparison. If a quote doesn't include installation, site prep, training, and disposal, it's not a complete quote.

4. Treat implants like the high-stakes inventory they are

A dental implant is tiny enough to fit in a small container, but it behaves like capital equipment when it comes to lot traceability and shelf life. My mistake was accepting a starter inventory without logging the lot numbers and expiration dates that were printed on every box. I looked at the labels. I just didn't record them.

Under the FDA's UDI system (21 CFR Part 830), implantable devices carry unique identifiers for a reason—so facilities can trace inventory when something goes wrong. That system only works if someone records the identifier before the box goes into a drawer. We lost two expired implants to the trash and, worse, wouldn't have been able to trace a recalled lot to a specific patient if we'd needed to.

Now every implant order includes a receiving step where someone scans or logs the lot and expiry date before the inventory is stocked.

5. Calculate cost per patient-day before you switch consumables

Not every mistake involves a six-figure machine. Our long-term care unit once switched adult briefs to a lower-cost option because it saved two cents per unit. The finance spreadsheet looked great for about a month.

The types of incontinence products sound straightforward—briefs, pull-ups, underpads, booster pads—but each type has a different clinical fit. The cheaper product held less, which meant residents needed more changes, more laundry, and more caregiver time. The "savings" disappeared, so we quietly switched back. Cost per unit is not cost per patient-day, and the second number is the one that runs a facility's budget.

6. Ask what's not included before you ask the price

I've learned to ask "what's NOT included" before I ask "what's the price?" The vendor who lists all fees upfront—even when the total looks higher—usually costs less in the end. The vendor who shows up with a low number and adds freight, rigging, installation, training, and old-equipment removal later will always be more expensive than the honest total.

That isn't a criticism of any one company. It's a warning about how I let a low number fool me. Twice.

7. Make sure more than one person knows how to run the thing

The last step sounds soft, but it has saved us more than once. If the vendor trains only one person on the dental x-ray machine, or one person knows where the service documentation is stored, your facility is one resignation away from being stuck.

When we finally got our service access sorted for the surgical tables, the biomed tech who handled it left two months later. It took three people and a long email chain to find the account credentials again. Every purchase now has a second name attached: the backup person who receives the same manual, the same training, and the same logins.

Common mistakes I still watch for

• Substituting an "equivalent" consumable without the clinical team approving it—especially for process tests like the RESI test.
• Letting a one-time installation cost hide in a capital quote while the follow-up support costs show up later as change orders.
• Logging implant lot numbers only when a recall happens.
• Assuming a lower-cost clinical product is the same product with a different wrapper.

This checklist sounds simple. It has still caught, by my rough count, 47 potential errors in the past 18 months—some as small as a missing disposal fee, some as serious as the wrong reprocessing test being added to an order. I might be overcounting because I include near-misses now, but that's exactly the point.

Bottom line

Everything I'd read about medical equipment purchasing said to compare specs, compare unit prices, and let competition do its job. In practice, the most expensive mistakes I made came from assumptions—about service, installation, consumables, and the person who would inherit the knowledge. Run this checklist before you sign and you'll avoid the mistakes that only show up after the invoice is paid.
