Mr. Jones ate some bad guacamole
press on his belly, he shouts "holy moley!"
we did a CT
and what could it be?
then he went for a lap'r'scopic chole
Mrs. Smith was awoke from her nappy
her belly was feeling quite snappy
white count? twasn't high
a fever? tad shy…
but the CT, of course, showed an appy
there once was a man from Bologna
thought he had caught a touch of pneumonia
he seemed like whiner
and he got a d dimer
no PE; just some bad allodynia
Of course the cake goes to:

A number of Very Smart People (including Rob Huang, Minh Le Cong, Chris Nickson, and Reuben Strayer) have all pointed out that Cochrane is supposed to summarize the data, not editorialize:
@DocBrent @HumanFact0rz @CochraneAnaesth cochrane shud stay away from clinical interpretation - just crunch the data, let clinicians decide— Chris Nickson (@precordialthump) November 4, 2015
Ultimately, this isn't that big deal. Hyperkalemia is bad, but rare. But if we can avoid it without worsening time to onset or intubating conditions, why not?
Special thanks to Minh Le Cong & Reuben Strayer for their prepublication peer review.

Andrew Sprung and I had a great conversation about Republican presidential candidate Donald Trump's claim that premiums are rising (see the Storify below). Our view: premiums are generally flat. There is a lot of variation around this, mostly geographic, and also largely based on whose premiums you're talking about. Comparing premiums from before Obamacare to today’s is like comparing 1995 and 2015 cell phone plans. [caption id="attachment_5826" align="alignleft" width="300"] Source: Lauren (Flickr/CC)[/caption] Yes, some people who were insured on the non-group market prior to the ACA saw their premiums go up significantly. But this is a meaningless critique. First, the fraction of people who had non-group plans prior to the ACA is (and still is) pretty small - about 5% in 2011 [source: KFF]. Second, remember that most people who have individual plans only have them for a fairly short period of time; most only enroll in a plan for 6-18 months, such as for a few months while searching for a job and until their next employer-sponsored plan kicks in (see this post for example). And while some were happy with their coverage, remember the two most important caveats to pre-ACA nongroup premiums:
- What did these plans cover?
- Who didn't these plans cover?
"If you think government healthcare is bad, wait until Comcast runs it." - SethPersonal example #1: I (Seth) had cheap private insurance for a few years in med school after getting kicked off my parents plan well before age 26 (Thanks, Obama) and I paid $60+ a month for essentially useless coverage that didn't really cover anything. Fortunately, I never got sick and I only really needed my insurance to satisfy my school’s requirement (and, maybe, piece of mind. But not really). While we don't know how many people were "happy" with their pre-ACA plan, we can estimate. Per Andrew Sprung, about half of the 16% of people in the non-group market now have grandfathered plans... which is roughly 1/2 of 1/6 of 1/20 of the insurance market, so 1 in 240 insurance plans. The second of these major issues that arises when comparing premiums before and after the ACA: preexisting conditions. How many people were completely blocked from getting insurance because of a preexisting medical problem? And relatedly, how many people were either charged higher premiums because of a preexisting condition? Or, were only given a plan that didn’t cover anything remotely related to their preexisting condition? ("You can buy insurance from us but we won't cover surveillance or treatment for a relapse of your Hodgkin's Lymphoma.") Personal example #2: My (Seth’s) wife was previously charged more (plus had to do a ton of frustrating paperwork) for the preexisting condition of "having a pre-cancerous benign mole removed." Remember: private insurance companies aren’t incentivized to keep us healthy; they are incentivized to keep us healthy until we turn 65. While a small fraction of individuals now pay a little more for their premiums, their insurance actually now has to cover stuff; and, they aren't getting a discount by excluding all the people who have serious health problems (or benign moles). Given all these caveats, it's really remarkable that premiums are pretty much flat at all. Let’s consider one last thing. “Premium price" can mean a lot of things. Is it subsidized or unsubsidized? Subsidized premiums are most likely pretty flat, and are what individuals actually pay. Unsubsidized premiums have gone up, but not by as much as people like Trump claim. I'm the first to admit that probably the biggest question the ACA poses is: will premium subsidies simply cost too much? And so far, it doesn't seem like it.
We have a great review forthcoming from Laura Medford-Davis on this issue. Stay tuned! - CedricPremium subsidies are simply the price we pay for insuring millions and millions of Americans in a functioning market for non-group insurance. And let’s not forget the quasi-secret but much, much, larger subsidies we already provide to people insured through their employers. We shouldn’t decry subsidies for insurance bought on the market while spending hundreds of billions of dollars subsidizing employer-sponsored insurance.

This fantastic article by Dan Diamond in Forbes on Republican presidential candidate Donald Trump’s gibberish on health care during his 60 Minutes interview sparked some great discussion on Twitter – see the Storify below. Dan makes an amazing analogy:
Blaming Obamacare for insurance companies’ behavior is like saying Trump’s responsible for how America nominates its presidents.Dan’s piece did, however, clumsily brush over one important issue, saying:
Trump has returned time and again to the idea that there’s not enough competition in the health insurance market. And you know what? He’s probably right. More than 40% of the doctor networks available through Obamacare exchanges are narrow network plans. Around half of all hospital networks on ACA plans are narrow networks, too.This isn’t so much wrong as it is non sequitur. Narrow network plans aren’t evidence of insufficient competition in the health insurance market; narrow network plans are the result of competition and negotiation in the health insurance market.
Insurers try to find the best provider network (providers include both hospitals and doctors, which are negotiated separately) for their plan at the lowest cost, mostly using their enrollees as leverage. Insurers try to negotiate a discount by bringing volume. Plans basically say to providers, “Take this price and look how many patients we will bring you!”
Hospitals and doctors negotiate for the highest prices and the largest volume of patients they can get, leveraging their quality and brand name (i.e. desirability).
The main “market interaction” in the insurer-provider market is defining the network for the plan. This is primarily how premiums and other costs are determined (in addition to deciding which benefits are covered by the plan).
Incidentally, this is pretty much why selling plans across state lines doesn’t magically fix anything. Consider this example.
An insurer in Illinois still has to negotiate a completely separate provider network if it were to try to sell a plan in another state like Indiana or Georgia. That’s where all the work exists. It’s not the regulatory burden; it’s the provider network negotiation.
There is, in fact, a lot of competition in health markets, primarily in the negotiations between insurers and providers. All Obamacare did was make it so that for insurers to complete against each other they had to come up with new ways of making profits while keeping premiums and cost sharing competitive. Instead of the pre-ACA race to see which insurer could exclude the riskiest people, now insurers fight over patients by cutting costs while maintaining required coverage — and the primary way to do that is by narrowing networks and excluding providers that don’t (as Trump would say) “cut a deal.”
