Oregon passed a law attempting to ban the corporate practice of medicine. It’s probably not going to work? There are carveouts. It would still allow for private equity to use a puppet doctor to run the show equally poorly (already common practice). It doesn’t address hospitals/health systems taking over the world, which often use the same corporate playbook. And none of it addresses the fact that access to capital, regulation, and reimbursement make it really hard to be small in medicine.

But it’s a start.

From Obsolescence Rents: Teamsters, Truckers, and Impending Innovations, published by the National Bureau of Economic Research:

We consider large, permanent shocks to individual occupations whose arrival date is uncertain. We are motivated by the advent of self-driving trucks, which will dramatically reduce demand for truck drivers. Using a bare-bones overlapping generations model, we examine an occupation facing obsolescence. We show that workers must be compensated to enter the occupation – receiving what we dub obsolescence rents – with fewer and older workers remaining in the occupation. We investigate the market for teamsters at the dawn of the automotive truck as an á propos parallel to truckers themselves, as self-driving trucks crest the horizon. As widespread adoption of trucks drew nearer, the number of teamsters fell, the occupation became ‘grayer’, and teamster wages rose, as predicted by the model.

“Obsolence rents” is a neat phrase. I remember a friend growing up whose aging father made a great living maintaining legacy systems in the nearly defunct computer language COBOL.

A new small AI sentiment study, as summarized in Becker’s: “Patients undergoing mammography preferred having their images interpreted by a radiologist before and after AI review.”

Having their imaging interpreted by AI alone was acceptable to 4.44% participants.

Having their imaging interpreted by AI after radiologist interpretation was acceptable to 71% of participants.

The finding that 4% of people were already (incorrectly) comfortable is the most interesting thing about this study. We are so early in the game here, and the current tools so unrobust, that almost all the opining about AI diagnosis is only meaningful as a snapshot for the historical record and a ward against the hindsight bias when inevitably most predictions are wrong most of the time.

A struggling post-bankruptcy Envision was so desperate to get out of their radiology business—presumably due to the impossibility of recruiting/retaining, meeting clinical obligations, navigating the general tumult, etc.—that they have agreed to “transition” their remaining practices/contracts to RadPartners. Sounds like they already shed the salable groups/assets/non-competes, so this is most likely a final liability dump/hand-washing endeavor. It’s unclear how much money exchanged hands for the remaining 400 rads and some desperate/unhappy hospitals.

The toddler puts on a show of having an argument, but they are holding a tantrum in reverse. If they ‘win’ the argument, no tantrum is needed. If they lose, they can tell themselves that they tried but the other person deserved the tantrum because they didn’t listen.

I signed up for my Threads and my Bluesky accounts in addition to OG Twitter/X or even LinkedIn a while back but never started really using them (@benwhitemd across the board, links above–give me a follow?). I’ve now set those up so that I can more easily share tweets of new blog posts across all platforms to account for reader preference (and I even added the cute little logos to my sidebar here).

A Doximity “2024 recap” email reminded me that it was exactly one year ago today that I first wrote about job boards in radiology because of those misleading listings from RP. That’s what first got me thinking about doing something different with Independent Radiology (and the monthly jobs post). I’m glad it’s working so far with our field’s current market and tumultuousness.

// 01.05.25

It is because doctors are understood to place patients’ interests above commercial ones that they have long enjoyed professional autonomy and public trust. The history of medicine is too littered with incompetence and immorality to believe that doctors have always been worthy of this status. Still, something profound is lost when we submit to the jaundiced view that medicine is a business like any other. There is value in striving for something higher.

I started Independent Radiology–a job board exclusively dedicated to featuring physician-owned private practices–on August 14. This past weekend we hit a major milestone I wouldn’t have predicted: 100 groups advertising their openings. The level of group and user engagement has been great to see.

If you’re a trainee going to RSNA this year, I’ll be giving a talk about careers in radiology during Session M3-RCP20: Navigating the Job Market at 9:30am on Monday. Come say hi!

They used to say academics was less production/pay and private practice was high stress/high comp. The gap has narrowed because the academy is demanding much more, lots of rads are just nonacademic employees of the university behemoth working a generic job, and the labor shortage means hospitals/universities need to pay more to compete in the job market.

Perhaps counterintuitively, strong private practice in the face of the labor shortage is one of the factors driving up academic compensation.

It’s an incredible privilege to work at a place and live in a country that is willing to set aside money to answer these existential questions. I heard a phrase the other week, existential humility, and I really liked that. We’re this complex life form that has evolved over billions of years to the point where we can ask these questions — and yet we’re perhaps not the only ones in the universe. And if we could know that for certain, that would be humbling in the most wonderful possible way.

Another paper suggesting that clinicians prefer some structure (but not too much structure) in radiology reports. There are always edge cases where structured reporting becomes cumbersome–and overly parsed reports are also inefficient/unreadable–but there’s no denying it’s so much easier for me to scan a prior report when it’s not narrative free text.

// 10.06.24

A reader asked if anyone had successfully started a new radiology private practice recently, particularly one that involved financing, opening up new imaging centers, and fresh payor contracts. There is a vacuum in some areas, especially with the PE-exacerbated instability, and therefore a clear opportunity to those who can muster the manpower (no easy feat).

As a follow-up, I thought I’d ask (on their behalf): is anyone who has willing to mentor other upstarts?

The month of August has been almost exclusively related to the usual activities of daily living and the new/growing job board I’ve started dedicated to true independent physician-owned radiology private practices, which now has 45 groups. I know a service like Independent Radiology probably has more impact than my usual sporadic writing, but I’m personally looking forward to getting back to my usual idiosyncrasies in September.

  1. Yes, I’ve started the process of creating a small dedicated job board just for independent radiologist-owned private practices. With all the corporate noise out there, I’m hoping we can connect radiologists looking for the real deal with those groups who are doing it. Still a ways to go, but feel free to reach out to me at ben@benwhite.com if your group is interested, and I’ll get back to you when things are ready.
  2. Separately, yes, for the first time in this site’s 15-year history, I’ve decided to run a real ad. Not a banner ad (and no images), but starting on June 1st, there will be a single monthly post featuring a limited number of true radiology private practices. I’ve temporarily changed this policy because of the radiologist shortage combined with the current less-than-stellar recruitment/marketing environment. I hope folks find it unobtrusive and even helpful; I’ll reevaluate in a year.

The tale of case review at Cigna in ProPublica:

“Deny, deny, deny. That’s how you hit your numbers,” said Day, who worked for Cigna until the late spring of 2022. “If you take a breath or think about any of these cases, you’re going to fall behind.”

[…]

The early 2022 dashboards listed a handle time of four minutes for a prior authorization. The bulk of drug requests were to be decided in two to five minutes. Hospital discharge decisions were supposed to take four and a half minutes.

[…]

As ProPublica and The Capitol Forum reported last year, Cigna built a computer program that allowed its medical directors to deny certain claims in bulk. The insurer’s doctors spent an average of just 1.2 seconds on each of those cases.

If you have HBO Max, standup comic Alex Edelman’s one-man show was excellent. The official description of its main narrative thread: “In the wake of a string of anti–Semitic threats pointed in his direction online, standup comic Alex Edelman decides to go straight to the source; specifically, Queens, where he covertly attends a meeting of White Nationalists.” Here’s the trailer.

I got an underdesk elliptical a couple of weeks ago…I think maybe it’s awesome and wish I had gotten one a long time ago. I’m honestly a little surprised I can pedal while thinking.

Fresh off the press in AJNR:

Lower [neuroradiology] shift volumes yielded significantly lower error rates. The lowest error rates were observed with shift volumes that were limited to 19–26 [CT/MRI] studies. Error rates at shift volumes between 67–90 studies were 226% higher, compared with the error rate at shift volumes of ≤ 19 studies.

I wonder, are there any places in the world routinely reading ~20 cases per shift?

C.S. Lewis (of Narnia fame) on peer learning:

It often happens that two schoolboys can solve difficulties in their work for one another better than the master can. The fellow-pupil can help more than the master because he knows less. The difficulty we want him to explain is one he has recently met. The expert met it so long ago he has forgotten.

I’ve always been a big proponent of peer teaching and peer mentoring in medicine. I also often wonder if I’m getting worse at teaching the basics as I get older.

From “How to Do Great Work” by Paul Graham:

Schools also give you a misleading impression of what work is like. In school they tell you what the problems are, and they’re almost always soluble using no more than you’ve been taught so far. In real life you have to figure out what the problems are, and you often don’t know if they’re soluble at all.

Schools sometimes also give students the misleading impression that learning is not fun for its own sake and that writing should be boring.

From “The Bitter Lesson” by Rich Sutton:

In speech recognition, there was an early competition, sponsored by DARPA, in the 1970s. Entrants included a host of special methods that took advantage of human knowledge—knowledge of words, of phonemes, of the human vocal tract, etc. On the other side were newer methods that were more statistical in nature and did much more computation, based on hidden Markov models (HMMs). Again, the statistical methods won out over the human-knowledge-based methods. This led to a major change in all of natural language processing, gradually over decades, where statistics and computation came to dominate the field. The recent rise of deep learning in speech recognition is the most recent step in this consistent direction. Deep learning methods rely even less on human knowledge, and use even more computation, together with learning on huge training sets, to produce dramatically better speech recognition systems. As in the games, researchers always tried to make systems that worked the way the researchers thought their own minds worked—they tried to put that knowledge in their systems—but it proved ultimately counterproductive, and a colossal waste of researcher’s time, when, through Moore’s law, massive computation became available and a means was found to put it to good use.

We want AI agents that can discover like we can, not which contain what we have discovered. Building in our discoveries only makes it harder to see how the discovering process can be done.

My crystal ball is as cloudy as ever.

Earlier this month I wrote about Radiology Partners loaning a group money to help shore up radiologist compensation. That happened, but I was also wrong in my estimation of the likelihood of repayment: it turns out RP may be getting some of that money back after all.

The ultimate outcome is still up in the air, but I’ve addended my previous post with an update.

From “Serious Medical Errors Rose After Private Equity Firms Bought Hospitals,” reported by the NYT:

The study, published in JAMA on Tuesday, found that, in the three years after a private equity fund bought a hospital, adverse events including surgical infections and bed sores rose by 25 percent among Medicare patients when compared with similar hospitals that were not bought by such investors. The researchers reported a nearly 38 percent increase in central line infections, a dangerous kind of infection that medical authorities say should never happen, and a 27 percent increase in falls by patients while staying in the hospital.

“We were not surprised there was a signal,” said Dr. Sneha Kannan, a health care researcher and physician at the division of pulmonary and critical care at Massachusetts General Hospital, who was the paper’s lead author. “I will say we were surprised at how strong it was.”

People like to operate under the belief that services like anesthesia, radiology, and pathology are totally interchangeable commodities. We do the work but don’t generate it, and patients generally don’t get to pick.

But in the real world, labor isn’t as cog-like as you might think, and culture matters (yes, even in our dysfunctional healthcare system).

Here, enjoy this story of a failed private equity anesthesia takeover.

The UnitedHealthcare vs Radiology Partners lawsuit went to arbitration instead of a jury trial last month. Last week, the arbitration panel ruled in favor of RP and its practice Singleton Associates, awarding them $153.5 million.

United, for its part, says it’s not done, and that there are still unaddressed counterclaims. From that Radiology Business article: “We do not agree that Singleton will recover an award from UnitedHealthcare,” the Minnetonka, Minnesota, company said.

Two great quick radiology podcasts, well worth your time for a better understanding of radiology in 2023:

First, the state of the radiology residency match and how things look for medical students as well as the radiology workforce, courtesy of Dr. Francis Deng (@francisdeng). I agree with everything he said, and he said it better than I would have. Listen here.

Second, episode 2 of the Texas Radiological Society’s “How Radiologists Get Paid” Podcast: a great discussion of the state of payment policy between Dr. Kurt Schoppe, policy wonk and my colleague across town, and Dr. Lauren Nicola, current Chair of the Reimbursement Committee at the ACR.

From the short essay, “Energy Makes Time,” by Mandy Brown:

But there’s something else I want to suggest here, and it’s to stop thinking about time entirely. Or, at least, to stop thinking about time as something consistent. We all know that time can be stretchy or compressed—we’ve experienced hours that plodded along interminably and those that whisked by in a few breaths. We’ve had days in which we got so much done we surprised ourselves and days where we got into a staring contest with the to-do list and the to-do list didn’t blink. And we’ve also had days that left us puddled on the floor and days that left us pumped up, practically leaping out of our chairs. What differentiates these experiences isn’t the number of hours in the day but the energy we get from the work. Energy makes time.

The what is sometimes even more important than the how much.

From the free ebook A Manifesto for Applying Behavioral Science from the UK’s Behavioural Insights Team:

The other concern is that [behavorial science] theories can make specific predictions, but they are disconnected from each other – and from a deeper, general framework that can provide broader explanations (like evolutionary theory, for example). The main way this issue affects behavioral science is through heuristics and biases. Examples of individual biases are accessible, popular, and how many people first encounter behavioral science. These ideas are incredibly useful, but have often been presented as lists of standalone curiosities, in a way that is incoherent, reductive, and deadening. They can create overconfident thinking that targeting a specific bias (in isolation) will achieve a certain outcome.

Cognitive biases and mental models make for great blog posts but are really hard to put into practice as an individual or effectively guide policy as an organization.

In a similar vein to our recent discussion of radiology practice and game theory, this is from Andrew K. Moriarity’s new article in JACR, “Pirate Practice”:

Employed sailors could count on the guarantee of agreed-upon pay in return for work performed. However, each pirate must be primarily motivated to ensure group success by their own self-interest because each endeavor lasted only as long cooperation maximized profits over expenses.

In considering the cooperation needed among individuals for a successful voyage to keep moving forward, perhaps Jack Sparrow was right to conclude that “not all treasure is silver and gold, mate.”
