You're a resident right?
I particularly enjoyed the dig about practicing medicine that was "vogue in the 2000s" (was it actually THAT long ago? Damn, I feel old..) and then you start quoting me a journal article from 1987 and 2006. Give me a second to LOL.
There's nothing wrong with RIFLE or AKIN. Period. Plenty of nephrologists use them. Both classification systems are well accepted in most medical communities.
AKI can be defined as an abrupt (1 to 7 days) and sustained (more than 24 hours) decrease in kidney function. The ADQI formulated the RIFLE criteria in 2004 to allow for AKI to be objectively and uniformly defined.

In May 2004, a new classification, the RIFLE (Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease) classification, was proposed in order to define and stratify the severity of acute kidney injury (AKI). This system relies on ...

I'm well aware of the confusion in hypertensive definitions over the years. I wouldn't hang your hat on JNC-8. The term "hypertensive urgency" is anything but moribund and redundant. Along with JNC 7, you've still got 2013 ACEP and 2013 ESC/ESH HTN Guidelines, all of which relatively define hypertensive urgency. There's nothing magical about the word, btw. They are all conveying the same thing...elevated HTN without end organ damage. The problem in the real world, such as the ED, is that people take this term and run wild with it. There's no strict definition of upper limits of "safe to discharge" and people will take a 280/140 BP with "clean labs" and argue that they are asymptomatic and d/c them out the door stating ACEP guidelines. I would argue that the authors of these definitions and guidelines never intended patients with extreme BPs to be discharged with no anti-HTN therapy. Call up a cardiologist and ask them if it's safe for you to send home a 280/140 and he will laugh in your face over the phone. Anecdotally, for many of us dealing with pt's returning or presenting to the ED with HTN emergencies, this practice doesn't seem safe and I think that would be validated if a study were ever created to track pt's at the upper extremes of "HTN Urgency or Asymptomatic HTN" compared to ranges that were less extreme. It's also ridiculous from a real world and practical perspective for those of us that have been doing this awhile. Let's say we send out an extremely elevated BP to the PCP office. What does the PCP do? He calls the CMO or ED Dir and asks why his pt wasn't admitted that he sent over there for extremely elevated BP. You d/c them to see a cardiologist and he does the same...sends them right back to the ED for BP control. Unless you're a resident in the ED, you're probably not dealing with these patients as most floors would not even accept them with BPs in that range. If they are in the ICU, they are probably already on cardene gtt, etc..
"Kills me when I see interns do X" Again, massive eye roll when I glance at your posts and realize you are a resident who was chasing up with your attending a few weeks ago.
Look man, it's not that I don't mind the posts. Thanks for the contribution. It's just that many times on here I see residents post very authoritative dissertations about something they're anything but an expert on. Come find me and talk renal dysfunction classification systems and HTN emergencies after you've been in a few hospital systems and been practicing on your own for a few years and realize that these two topics are anything but black and white.
The whole point with renal "failure" is that it is a definition used in ACEP Facility Level Coding guidelines for CPT
99291. Any qualifier used in the definition is going to encourage clinicians to utilize classification systems that discretely define "renal failure", hence why I'm even using RIFLE.
