New paper w/ Brian McGarry, Ashvin Gandhi, and Drew Wilcock in @jamainternalmed.com!

Hospitals are complaining across the US that patients are "stuck" waiting for rehab beds at nursing homes when they are medically stable and ready for discharge. What is going on??

Question Has hospital length of stay increased more for Medicare Advantage beneficiaries than for traditional Medicare beneficiaries since the COVID-19 pandemic?Findings In this cohort study involving more than 89 million hospitalizations from 2017 to the third quarter of 2023, Medicare Advantage beneficiaries experienced disproportionately greater increases in extended hospital stays, especially among those discharged to skilled nursing facilities.Meaning These findings suggest that the Medicare Advantage plan design and practices may contribute to hospital discharge delays, with implications for patient outcomes and hospital capacity as enrollment continues to rise.

Ipsos finds Trump’s approval rating is decreasing almost entirely because of anti-incumbent economic anxiety. Approval rating among people who say the economy is the # 1 issue is -24pts since Jan. It’s stable for people who index on all other issues www.ipsos.com/en-us/lesson...

Why is Trump proposing a weird subsidy program that actually sounds like the ACA?? The truth is that Obamacare is fundamentally very conservative (Mitt Romney's plan!) and any attempt at meaningful reform can only go left ... Who will we buy health insurance from again?

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

If fixable, I would make them fix it as disincentive to obfuscate. If it's high quality research otherwise there are lots of reasons why the intro might hide info. Could be something one author did and the others are unaware or want to fix it and need permission.

it is coming to my attention that a lot of people in the mid-late career start going insane when they realise that all they have worked to attain is in fact ephemeral and fleeting. adding this to the packet of failure modes to be cautious about.

I finally made the switch to R from stata, and as a fierce long-time defender of stata, I can concede that R is leagues better in almost every way.

Still, I do wish there was an easier way to diagnose merges w/o complicated code. GPT hasn't helped, and joyn doesn't seem to do it right. Any advice?

More CDC Cuts :: NCHS Edition 📊🔫

At least 1/3 of the staff at the National Center for Health Statistics has been cut (and remain cut). This is catastrophic for our nation’s health data.

Say goodbye to national health statistics that you can trust, healthcare surveys, NHANES and data systems.
