In the operating room, surgical masks and matching scrubs can make it hard to tell who's whom — at least for outsiders.
Patients getting wheeled in might not realize that salespeople working on commission are frequently present and sometimes even advise the clinical team during surgery.
Who are these salespeople, and why are they there?
The answer to the first question is pretty easy. These sales reps typically work for medical device companies, such as Stryker, Medtronic or DePuy Synthes. Many surgeries, especially orthopedic trauma and cardiac procedures, require insertion of artificial joints or other hardware manufactured by these companies.
But as to why they're present in the operating room, the answer depends on whom you ask.
Critics of the practice contend that device reps attend surgeries to strengthen their relationships with particular surgeons and thereby persuade them to choose one brand of artificial hip joint or stent or pacemaker over a competitor's.
The device reps contend they observe surgeries because they are experts on particular devices and their accompanying toolkits, which often include hundreds of wrenches, screws and other hardware to aid in installation.
Sometimes, the device reps have observed more surgeries with a particular device than any one surgeon. That depth of experience can be helpful, the reps say, especially with the newest device model or upgrade.
"I can't keep my socks together through the dryer. You can imagine trying to get 100 pans or 300 pans of instruments all set up correctly," says orthopedic surgeon Michael Christie of Nashville, who specializes in new hips.
Device reps have been attending surgeries for years, but that practice is coming under new scrutiny. As baby boomers age, there has been exponential growth in device-dependent procedures like total joint replacements. In addition, insurers are starting to crack down on health care costs, telling hospitals that they'll only pay a fixed price, known as a "bundled payment," for certain surgical procedures, such as hip or knee replacements.
That approach has forced hospitals to take a hard look at the price tags of the devices and the salespeople who are pushing the latest models. Hospitals are "starting to figure out what these reps make for a living. They feel like they're making too much money, and I think that's why they want them out," says Brent Ford, a former sales rep who now works for Nashville-based HealthTrust, a firm that handles contracting and purchasing of supplies like hip implants for 1,600 U.S. hospitals.
Medical device reps are more often business majors than biology buffs, but they train for the job as if they might have to conduct surgery themselves. At an educational center in Colorado, future reps learn how to saw off a hip bone and implant an artificial hip.
Their corporate training frequently involves cadavers, which helps reps develop the steel stomach required for the unsettling sights and sounds of an orthopedic operating room — like a surgeon loudly hammering a spike into a bone.
"Before we're allowed to sell our products to surgeons, we have to know the anatomy of the body, go through tests of why physicians use these types of products and how we can assist in surgery," says Chris Stewart, a former rep for Stryker, one of the largest device manufacturers.
Stewart now works for Ortho Sales Partners, a company that helps device manufacturers navigate relationships with hospitals.
Keeping those relationships strong is crucial, because hospitals don't have to allow reps into their operating rooms. But if reps are allowed, there are rules: Reps can't touch the patient or anything that's sterile.
Big companies like Stryker have developed detailed policies for their own reps about how to behave in the operating room. And some hospitals, like hospital chain HCA's flagship medical center in Nashville, have instituted even stricter rules — selling is banned in the OR and reps are only allowed to provide support for surgical cases.
But Stewart maintains reps still can be useful. Some help surgical assistants find a particular tiny component among the trays of ancillary tools. Some reps even deliver the tool trays to the hospital themselves, prior to the surgery. They want the procedure to run as smoothly as possible so that a busy surgeon will become a steady customer.
"Obviously, there's a patient on the table being operated on, so that's where the sense of urgency is," Stewart says. "You have to become an expert in understanding how to be efficient with helping everyone in the OR making sure your implants are being utilized correctly."
Keeping up with technology
Stewart says it has become difficult for the hospital staff to keep pace with constant design changes for artificial joints or spinal rod systems.
But the speed of innovation concerns some researchers, including Adriane Fugh-Berman, a Georgetown University medical doctor who studies the relationships between industry and physicians.
"What we need are skilled helpers in the operating room who are not making money off of the choices of the surgeons," she says.
Fugh-Berman has come to believe that reps should be banned from operating rooms. Her biggest concern is safety, including the occasional violations of sterile protocol. As part of her research, she anonymously interviewed reps who said they're instructed to always push the latest, most expensive products, even when the old version is more proven.
"The newest device is not necessarily the best device," she says. "In fact, it may be the worst device."
Yet safety issues are not what has worn out the welcome for some reps — it's their potential influence on surgical costs. Their exact effect remains hard for hospitals to quantify, but hospital executives now have a new incentive to push back on the role of the rep because insurance reimbursement formulas have changed.
For example, in 2016 the government-run Medicare program began changing how it pays hospitals for a joint replacement — from a traditional billing-for-costs model to a fixed-dollar amount for each surgery. It's a cost-control move, because joint replacement has become one of the most common reasons for inpatient hospitalization for Medicare patients.
Increasingly, hospitals are feeling the squeeze of these new payment caps.
"They're looking at costs and saying, 'I want to understand everything that drives cost in my OR,' " says Doug Jones, a former rep with DePuy who now works for HealthTrust to control surgical spending. "I think they're becoming more aware that that rep is in there and saying, 'Is there a cost associated with it?' "
HealthTrust hasn't been telling administrators to kick out sales reps. But it has been suggesting hospitals reassess their role. The company, which is a subsidiary of for-profit hospital chain HCA, has studied particular devices, like pedicle screws, often used in spine procedures. They cost anywhere from $50 to $100 to manufacture, but a hospital might pay a thousand dollars apiece to keep them in stock. One basic spine procedure can involve several screws and rods, with the sales rep standing to make a 10 percent to 25 percent commission on the equipment used, according to HealthTrust's market research.
And in many places, upselling occurs in the room, says HealthTrust's Ford. He recalls seeing reps encouraging a surgeon preparing for a procedure to use a fancier device that wasn't on the hospital's discounted list.
Other HealthTrust clients are starting pilot projects on running operating rooms without company-sponsored reps and buying equipment directly from smaller firms, which often have devices that are nearly identical to the brand names.
But getting rid of the rep may have hidden costs, too.
Joint replacements have become so routine that an experienced surgical team can nearly operate in silence. When the surgeon says "neck" and reaches out his hand, an assistant places the piece in his hand without a moment's delay.
The array of tools and components are often in the right place because a device rep made sure of it. Logistics is a big part of the job — delivering trays of instruments in the pre-dawn hours to be sterilized by the hospital, the "non-glorious side of being a rep," Ford says.
The logistical role has essentially been filled by the manufacturers instead of hospitals in recent decades. And now surgeons may trust their reps more than anyone else in the room. They're often the first call he or she makes when scheduling a case, to make sure the device will be ready to go.
"If that widget isn't there the next day when I'm doing a case and I need the widget, we're kind of at an impasse," says Christie, the Nashville-based joint replacement surgeon.
Many experienced surgeons, like Christie, also have financial ties to manufacturers, collecting substantial royalties for helping design new implants. As of 2013, these payments are now disclosed publicly. Christie, for example, was paid $123,000 by DuPuy in 2017.
An industry trade group spokesman defends the close relationship as a way to improve their products and provide hands-on training to surgeons. "Those are two areas where it's key to maintain a close, collaborative relationship, with the appropriate ethical limitations," says Terry Chang, associate general counsel for AdvaMed.
Filling a personnel gap
The overall result is that many clinicians are happy to have reps in the room.
"You say 'sales rep,' " says Marley Duff, an operating room manager at TriStar Centennial Medical Center. "I look at them more being somebody that's expertly trained in their field to provide support for the implants that they happen to sell."
Duff says reps can be especially helpful when a failing artificial joint needs to be removed and replaced.
Hospitals are reluctant to remove reps, for fear of irritating surgeons, who typically don't work directly for a particular hospital and could move their cases to another institution. Those hospitals experimenting with going "rep-less" have done so quietly and have had to hire additional staff to pick up the slack.
One of the first in the country to try, Loma Linda University Health, boasted in 2015 of reducing costs for total knee and hip replacements by more than 50 percent by going rep-less.
But a hospital spokesperson now tells NPR that the medical center has abandoned the effort, though she refused to discuss why.

ARI SHAPIRO, HOST:
Having surgery can mean entering a room full of strangers. And behind the masks and scrubs, it can be hard to tell who's who. As it turns out, salespeople are frequently present in the operating room. They are there because their company makes a medical device that a doctor is about to implant. This has been going on for years. And as Blake Farmer of member station WPLN in Nashville found, the practice is now under new scrutiny.
BLAKE FARMER, BYLINE: Hip and knee replacement is becoming so routine that a surgeon can operate nearly in silence, other than the hammering on bone.
(SOUNDBITE OF TOOL HAMMERING ON BONE)
FARMER: During a hip replacement broadcast on public television, the surgeon issues one-word commands.
(SOUNDBITE OF ARCHIVED RECORDING)
UNIDENTIFIED SURGEON: Neck.
FARMER: When he needs part of the artificial joint or the special tool used to install it, it's placed in his hand by the scrub nurse. But if this surgical team hasn't worked much with this surgeon, he might turn for guidance to the medical device sales rep. Often, that sales rep knows the surgeon and the equipment better than anyone in the room.
CHRIS STEWART: The back table of a OR is full of instrumentation.
FARMER: Chris Stewart spent his sales career with Stryker, one of the biggest device manufacturers.
STEWART: That's really where we come into play is knowing exactly what screwdriver to use, making sure that the screw is on the screwdriver.
FARMER: Device reps are trained as if they might have to conduct surgery themselves. At an educational center in Colorado, they saw through bone to install an artificial hip. Sometimes they even work on cadavers. That helps them develop the steel stomach needed to watch a spike hammered into bone.
STEWART: We have to know the anatomy of the body. You go through tests of why physicians use these types of products and how we can assist.
FARMER: Hospitals don't have to open their ORs to sales reps. So Stewart now helps device companies navigate their relationships with hospitals. He argues it's valuable to have reps there. They've often seen more operations with their implant than the surgeon has. Plus they help with logistics, delivering trays of specialized tools each morning for sterilization. Dr. Michael Christie of Nashville specializes in new hips and values his rep.
MICHAEL CHRISTIE: I can't keep my socks together through the dryer. You can imagine trying to get 300 pounds of instruments all set up correctly because if that widget isn't there, we're kind of at an impasse.
FARMER: But there are some inherent conflicts in these relationships. Many experienced surgeons like Christie get substantial payments from device makers, either royalties for their design contributions or speaking fees. And then there's the support reps provide in the OR. Dr. Adriane Fugh-Berman says licensed medical professionals should be doing that.
ADRIANE FUGH-BERMAN: What we need are skilled helpers who are not making money off of the choices of the surgeons.
FARMER: Fugh-Berman studies medical device sales at Georgetown University. She says reps are primarily interested in pushing their company's newest and most expensive product.
FUGH-BERMAN: The newest device is not necessarily the best device. In fact, it may be the worst device.
FARMER: She says it doesn't help that the FDA offers fast-track approval for some devices. One of them was a hip implant that was later found to be shedding tiny bits of toxic metal into patients' blood streams.
But for hospitals, controlling device sales is a business issue. Nowadays, many insurers, like Medicare, are capping what they'll pay hospitals for a hip replacement. Every expense is now under scrutiny.
BRENT FORD: I think there's more transparency with costs now.
FARMER: Brent Ford was a device rep but now works for HealthTrust. That company handles purchasing for hundreds of hospitals and now strongly urges them to reconsider whether highly paid sales reps should be welcome in the OR.
FORD: They feel like they're making too much money, and I think that's why they want them out.
FARMER: And yet experiments with going rep-less (ph) are having mixed success. One of the first in Loma Linda, Calif., claimed to save a million dollars a year buying discounted devices direct from the manufacturer. But the hospital also had to hire additional staff to fill the rep's role. Recently, officials there admitted to NPR they've abandoned the effort.
