Pocket Ultrasound Machines: "Why doesn't everyone have one of these?"


For about 2 years now a tiny ultrasound machine has been part of my standard physical exam tools as I take care of patients in the hospital and in the outpatient clinic. In November of 2011 I first picked up an ultrasound transducer in a continuing medical education course on bedside ultrasound for emergency physicians. I am an internist, not an emergency physician, but I was interested in bedside ultrasound and it was the emergency physicians who were giving the most interesting course. It was transforming for me. I was able to see internal anatomy and physiology and eventually, with lots of practice, I was able to make diagnoses more quickly and accurately. I bought a pocket ultrasound machine so I could make bedside ultrasound a seamless part of my practice

It was an unexpected and welcome bonus that my patients and their families loved it. I would share the moving ultrasound pictures with them, often having them hold the machine so I could point out how beautiful their internal organs were and what we could see that helped give us a clue about their disease process. Many of these same patients also got full, detailed ultrasounds or other imaging by radiology technicians, but since the technicians aren't supposed to discuss findings with the patients and often they couldn't see the screen, it wasn't nearly as gratifying.

The most common comment I get from patients is, "Wow, that's really cool!"  "I agree!" I answer. Then they will ask, "Why doesn't everyone have one of these things?"

That is kind of a difficult question. "They're pretty expensive," I usually say. They are. At least for now. The little machines (Vscan, by GE) retail for over $8000, though you can buy them cheaper used or overseas. Physicians balk at spending this amount of money on a piece of equipment. Most of the expensive gadgets we use are owned by hospitals or by our group practices. Musicians, however, who make a fraction of what we do, buy their own musical instruments which often cost in excess of $10,000. I'm not sure the cost ought to be a serious consideration. Other doctors often ask me if I bill for my exams. I don't, because billing and the detailed documentation and posturing that would be necessary to prove to an insurance company that an ultrasound was necessary would take more time than I have. I report the results in my narrative of the physical exam, much as I do the findings of my ears or my hands or eyes. There are billing codes for limited ultrasounds, and if I were able to record and store my images easily I could probably boost my revenue, but that would make me feel just a little bit conflicted every time I did it. I would have to tell the patient that I was charging for it which would probably make them feel conflicted as well, or maybe choose to forgo the exam, which would mean that I would know less about what was going on and would be more likely to make a mistake.

"It also takes a long time to learn," I add. I have spent hundreds of hours in  learning from good teachers, mostly in person, but also online. I have done many thousands of exams and have reviewed a fair number with experts. But it is actually pretty quick to get good enough to be sure of a handful of different things that make a huge difference in making clinical decisions. After that, much like most of the things we do in medicine, learning expands exponentially with on-the-job experience. Many students in medical school now are learning how to use ultrasound at the bedside as part of their standard training, which is really the best way to do it.

"When did those things come out? I've never seen anything like it!" say my patients. The little pocket model I have has been available for at least 5 years, and there have been portable ultrasounds for considerably longer. The company that makes mine has not been aggressive in marketing it, even though it is potentially as huge a deal as the introduction of the stethoscope, and other ultrasound companies have been incredibly slow in developing competitive models. Maybe it's just difficult to develop the technology, but I think it's a little less wholesome than that. Ultrasound is a huge part of what radiology departments in hospitals and clinics do. It has grown as we have become aware of the dangers patients are incurring with the expanding use of imaging based on x-rays, such as CT scans. Full scale ultrasound exams are performed by radiology technicians using machines costing hundreds of thousands of dollars, are read by radiologists or cardiologists and billed out for thousands of dollars each. If physicians at the bedside are doing these exams for free, or even for cheap, this has the potential to negatively impact huge revenue centers. It is not in the financial interests of the whole industry for the manufacturers to produce an awesome pocket machine. A bedside ultrasound, which takes minutes, is hardly the same as a full scale ultrasound or echocardiogram which can take almost an hour to perform by a technician who does only this. In some cases we may order more ultrasounds because of what we see, or think we see, at the bedside, but for some questions our brief and focused exam will be enough and will supplant imaging by the radiology department.

There is also abundant controversy about adding routine ultrasound to the way we practice medicine. It is a "disruptive technology" which means that it potentially changes things in far reaching ways, many of which can't be adequately predicted. We may see things inside patients that are best left unseen or are difficult to interpret. We may thus end up chasing findings that are nothing and costing patients more money and anxiety than we should. I have not found this to be true, however. Imaging of all kinds, especially the detailed kind that comes out of radiology departments, is often misleading and anxiety provoking. Think about the majority of mammogram abnormalities that turn out to be nothing or adrenal "incidentalomas," the small meaningless lumps we see on the adrenal glands when CT scanning the abdomen. Combining bedside imaging with examining the patient, talking to them and reviewing laboratory data has been much less likely to lead me to misdiagnoses than to appropriate ones.

Many older physicians are trying to adjust to changes that make them feel that they are losing the profession that they used to practice skillfully in the past. We are asked to learn to use computer systems to document patient visits, review medical histories and order treatments. We start to become data entry technicians, and we aren't very good at it. We are asked to learn continually changing algorithms for treating a myriad of diseases. We are required to provide excellent preventive medicine for our patients so they don't have heart attacks or strokes or get cancer, when research on the proper way to do this makes what was wise one day stupid the next. On top of this people like me with our tiny little ultrasound machines come along and say "Hey...there's this other thing you should do too..." But I would love for my overworked and stressed out colleagues to know that this is different. Data entry is not inherently fun. Robots or trained monkeys could probably stay on top of the preventive to-do list better than we do, and algorithms don't give us much job satisfaction, even if they do help us deliver evidence based treatments. Bedside ultrasound, though, is terrifically fun and despite the time and effort required, brings back some of the joy of being a real doctor. I say this after a quarter of a century of practicing internal medicine. I am an "older physician."

So, "Yes," I tell my patients. "I agree. It is incredibly cool. We are looking at the inside of your body together and learning things. It's unusual now, but I'm pretty sure it's not going to be too long before it's part of what most of us do."

How much did your 100+ hours of extra training cost you?
Janice Boughton said…
Good question. It cost a lot of money. Also time. I attended 3 continuing medical education courses, each of which cost maybe $3000 with travel and lodging. I spent $5000 on the tuition for a one month mini-fellowship but the real costs were much higher considering that I took a month off work and had to cover food, lodging and travel in a rather expensive location. I got a tremendous amount out of my first CME, though, and could have learned all of the rest of what I needed by hanging out in an ER with another doctor who did lots of ultrasound and by doing ultrasounds and reviewing ultrasound resources on youtube. The main reason I got excessively trained is so I could teach it and maybe make the process simpler and cheaper for other doctors. If this is going to become a standard part of what we do, we need to figure out some efficient methods of training each other.

I'm very interested in doing exactly what you've done. I want to incorporate this into my physical exam without necessarily turning it into a billing program. Any recommendations on which CME to start with? What ultrasounds did you choose?

I am a traditional internist and would be using this both in outpatient and inpatient setting.

I loved the Emergency Ultrasound course at Harvard, the one that Vicki Noble does at the Navy Yard. It was inspiring and fun and really instructive. I hear that UCSF does good courses, I also went to Yale's ER ultrasound course in Puerto Rico and this thing called "Castlefest" which the guys who do the online Ultrasound Podcast put together in Kentucky every year. I have done most of my training in ER courses because they have been doing ultrasound education longer than internists have and so they really know how to teach it. My mini-fellowship was through UC Irvine and if you live near there, they can be really flexible. If you want more information on that, let me know.
Cheeler said…
Hi Janicee. Thanks for the info. I live about 5h from Irvine but my employer is really interested in having me pave the way in this. I would be interested in the mini-fellowship if you can direct me to more details.

Also, are you using a GE Vscan portable? Thanks!
Janice Boughton said…
Yes. Contact Chris Fox MD at UC Irvine. He is the director of Emergency Ultrasound education and runs the mini-fellowship program. It's great that you are so close.

Cool post! I am a GP from Norway and think bedside ultrasound has awesome potential for all clinicians. Why not look into the body for valuable information when searching for a diagnose? I can recommend watching the podcasts at ultrasoundpodcast.com and join the virtual fellowship at ultrasoundleadershipacademy.com. Awesome program, I have been a virtual fellow since september of last year. Start ultrasounding, it will be a gamechanger and one of the most useful skills you'll learn as a doctor. Canh

While I agree on not billing separately for the POC ultrasound, is it possible to upcode the encounter because of the extra time/effort spent and note in the patient chart?
Janice Boughton said…
I agree. It feels to me like using ultrasound means I am doing a better job so I or the institution paying me should be able to bill more. It doesn't work like that now but it would be something to ask for. Ideally we would be paid to take care of populations and so doing a better and more streamlined job would be a natural direction to move.

How to make your own ultrasound gel (which is also sterile and edible and environmentally friendly) **UPDATED--NEW RECIPE**

I have been doing lots of bedside ultrasound lately and realized how useful it would be in areas far off the beaten track like Haiti, for instance. With a bedside ultrasound (mine fits in my pocket) I could diagnose heart disease, kidney and gallbladder problems, various cancers as well as lung and intestinal diseases. Then I realized that I would have to take a whole bunch of ultrasound gel with me which would mean that I would have to check luggage, which is a real pain when traveling light to a place where luggage disappears. I heard that you can use water, or spit, in a pinch, or even lotion, though oil based coupling media apparently break down the surface of the transducer. Or, of course, you can just use ultrasound gel. Ultrasound requires an aqueous interface between the transducer and the skin or else all you see is black. Ultrasound gel is a clear goo, looks like hair gel or aloe vera, and is made by several companies out of various combinations of propylene glycol, glyce

Ivermectin for Covid--Does it work? We don't know.

  Lately there has been quite a heated controversy about whether to use ivermectin for Covid-19.  The FDA , a US federal agency responsible for providing unbiased information to protect people from harmful drugs, foods, even tobacco products, has said that there is not good evidence of ivermectin's safety and effectiveness in treating Covid 19, and that just about sums up what we truly know about ivermectin in the context of Covid. The CDC, Centers for Disease Control, a branch of the department of Health and Human Services, tasked with preventing and treating disease and injury, also recently warned  people not to use ivermectin to treat Covid outside of actual clinical trials. Certain highly qualified physicians, including ones who practice critical care medicine and manage many patients with severe Covid infections in the intensive care unit vocally support the use of ivermectin to treat Covid and have published dosing schedules and reviews of the literature supporting it for tr

Old Fangak, South Sudan--Bedside Ultrasound and other stuff

I just got back from a couple of weeks in Old Fangak, a community of people living by the Zaraf River in South Sudan. It's normally a small community, with an open market and people who live by raising cows, trading on the river, fishing and gardening. Now there are tens of thousands of people there, still displaced from their homes by the civil war which has gone on intermittently for decades. There are even more people now than there were last year. There is a hospital in Old Fangak, which is run by Jill Seaman, one of the founders of Sudan Medical relief and a fierce advocate for treatment of various horrible and neglected tropical diseases, along with some very skilled and committed local clinical officers and nurses and a contingent of doctors, nurses and support staff from Medecins Sans Frontieres (Doctors Without Borders, also known as MSF) who have been helping out for a little over a year. The hospital attempts to do a lot with a little, and treats all who present ther
