1) Private Equity and Health Care Delivery by @brianwpowers @WillShrank @AmolNavathe

💯 Agree private equity isn't inherently good or bad "acts to amplify the response to extant financial incentives"

A couple of further points though....

ja.ma/3m6K6FU @JAMA_current
2) it's true that good policy can align private profit with public good, but if we are going to rely on that, need tight surveillance and fast response from regulators to close arbitrage opportunities where short-term profit maximizers will gather. c/f surprise billing
3/ if you wait too long, then entrenched profits become normalized, powerful incumbents are formed, and they can, and will, exert political influence to keep the "status quo" in place.

Many health policy examples (facility fees, drug pricing). But also...Medicare Advantage 👀
4/ It's true that fee for service creates a huge host of opportunities where private profit is not aligned with public good, in over-utilization where items aren't priced appropriately or restricted effectively...

PE rollups of derm practices -> MOHS surgery on the butt
5/ in creating monopolies where market power (or regulatory capture) can lead to higher prices (esp for commercial lives), like air ambulances, or anesthesiologists

In cutting back on costs in ways that stint on care, harm patients (see nursing home study)
6/ I am a huge believer in value based payment model as a massive force for good in better aligning public good with private profits.

But that doesn't mean that arbitrage opportunities can't creep in there.

Like medicare advantage risk adjustment

7/ I'm glad that @BrooksLaSureCMS @LizFowler_ @drmeenasesh vision for advancing value based care includes attention to risk adjustment

It's a tough problem, but when policymakers have tried to address it, barriers have been more political than technical. healthaffairs.org/do/10.1377/hbl…
8/ so, YES.

We all benefit when the only capital to grow disruptive models doesn't have to come from today's incumbent giants, who are not interested in disrupting their current comfortable status.
9/ YES. There are long term-oriented PE firms that aren't just about cutting costs, or financial engineering, but rather around creating lasting positive change, in a way that's aligned with social good (if for no other reason that those businesses tend to be more sustainable)
10/ YES. Simplistic PE-bashing is misdiagnosing the problem, ("don't hate the player, hate the game")

Trying to limit their participation in healthcare seems difficult and potentially counter-intuitive
11/ Policymakers that influence a significant portion of the incentives in the healthcare system have an awesome responsibility to always be on the lookout for emerging arbitrage being applied to any payment model, VBC as well as FFS, and to be constantly and quickly responding
12/ One of @N_Brennan unsung innovations at @CMSGov data unit was setting up an analytic function to track market developments and incentives

Maybe its a cat and mouse game, but that is the nature of life. There is no perfect solution that doesn't need constant attention.

1/ Here's another quiz for budding epidemiologists

The Guandong Delta outbreak was meticulously investigated. Initial report of 1000x viral load came from there

A finding that hasn't been discussed much is the seeming shorter incubation period (panel b)

virological.org/t/viral-infect…
2/ In 2021 delta it was only 3.7 days (vs 5.6 days for 2020 outbreak).

This would have an impact on a key transmission dynamic factor we often look for: "serial interval periods" (time between symptom onset for index case vs subsequent case in a contact tracing investigation)
3/ What you are trying to estimate from observable symptom intervals is underlying mean generation time.

tangent: If you find negative serial intervals as in COVID, it's a sign of asymptomatic and presymptomatic spread.

Without looking it up,

What is Rt in Arkansas right now?
Rt is actually 1.2 (0.98-1.5). It is taking 12 days (4 generations) to double

here's some math

If Rt (aka Reff) was 5, it would mean that it would go up 5*5*5*5 = 625 TIMES in 12 days, not 2x

epiforecasts.io/covid/posts/su…
3/ Now, we aren't living in an R0 world. Even though it may feel like it sometimes

People are vaccinated (despite breakthrough infections)
People are infected (despite reinfection risk)
People have changed behaviors

But "Delta variant is as transmissible as Chicken Pox"(R0~9)??

1/ Like many others, I've been frustrated that we haven't seen the data behind the CDC's new recommendations. Parsing exact wording in transcripts is🤦

We're told there will be a release tomorrow but thanks to the @washingtonpost there's an internal CDC document to parse tonight
2/ The article by @yabutaleb7 @carolynyjohnson @JoelAchenbach is here:
washingtonpost.com/health/2021/07…

TY @bijans for spotting the "full pdf" download button.
3/ what do we learn?

The mysterious "other data" for high viral load in breakthrough cases came from a 4th of July outbreak in Provincetown (Barnstable, Mass) where the “vast majority” of the new cases were among fully vaccinated individuals

1/ What percent of vaccinated people who get infected with covid will have long-term symptoms?

I don't know, but I highly doubt that it's 19%.

Here's why I say that, and what the *right* study design would be for answering that question.
2/ when I was an Epidemic Intelligence Service Officer at the CDC, I investigated lots of outbreaks, and every one would have a symptom checklist

A surprisingly high number of people with a diagnosed infection will say YES to a variety of symptoms

Fatigue?
Headache?
Fogginess?
3/ many of these reported complaints would have absolutely nothing to do with their infection.

But recall bias is super powerful, and respondents often feel like they're supposed to say "yes". So they do.

1/ Our national quality/value program (MACRA) is broken

Most people just complain about its shortcomings, but @Travis_Broome comes up with an elegant, grounded way to fix its biggest flaws

Apply behavioral economics, use virtual groups, lay path to APMs ajmc.com/view/macra-has…
2/ MACRA was a true milestone, and a concept that I still support- instead of artificially capping medical inflation (and then not having the guts to actually see doc pay cuts) lets create 2 paths- a "pay for performance" base and an incentivized alternative payment model track.
3/ But 3 seemingly technical details fundamentally sapped the potential impact of this huge bill.

classic behavioral economics- the impact of an incentive is not just proportional to its size, but also its cost, uncertainty, and delay

MACRA stunk on all counts here.

1/ "Federal antitrust oversight has proved inadequate at preventing anticompetitive effects across the health care sector" per @commonwealthfnd

What else can the federal government do, given the difficulty of passing healthcare legislation?

Plenty.
commonwealthfund.org/blog/2021/fede…
2/ in this article, Joseph Kannarkat and I break down all the tools that the Biden administration and @SecBecerra have to address competition beyond antitrust reviews

jamanetwork.com/journals/jama-…
3/ first of all, if the Biden administration chooses to elevate health care competition as a priority, it may garner rare bipartisan support.

This is an issue that has support from left (@ZekeEmanuel) and right (@Avik) thought leaders and legislators.
