Record retention is covered by a complex set of overlapping regulations and contracts. They are dependent on much more than date of service. M&A activity, interstate operations, subsequent changes in patient mental status, etc can all cause the horizon to change well after the last encounter.

As all the comments in this thread suggest the cost of having an extra record , even an extra breached record is low. The cost of failing to produce a required medical record is high.

Put this together with dropping storage prices, razor then margins, and IT estates made out of thousands of specialized point solutions cobbled together with every integration pattern ever invented and you get a de facto retention of infinity paired with a de jure obligation of could-be-anything-tomorrow.


I’m from a culture in which family use a very small number of very highly conserved names and non standard name positions. I’ve noticed this is sufficient to confuse the low rent data brokers that do statistical linkage. My parents and grandparents and my siblings and my children have all at various points shared addresses landlines and have overlapping names. The brokers are very unclear on how many people are involved , what sex , what generations what states.

This is a suboptimal characterization of this site.

I think it would be less wrong to say this is where covered entities that discover reportable breaches of PHI (whether their own or that of a BA) that trigger the immediate reporting obligation report them.

This is a narrower scope of coverage and shallower depth of epistemic obligation than you implied.


I don’t follow it but your last suggestion (use single income not household) was new to me and interesting in as much as it seems like an obvious extension of “The Two-Income Trap” thinking.

To some extent seems like it would also provide a margin of safety given homogeneity effects eg https://www.census.gov/content/dam/Census/library/working-pa...


Isn’t the obvious answer that many would refute the premise of meaningful regional variation? In which case the claim isn’t that somewhere else is that place but rather than all places are substantially equivalent on this difficult to measure concept (or difference is unknown).

An adjacent point but despite ubiquitous birth order superstitions quality literature consensus seems to be that birth order is not a large driver of predictable differences. Example:

This paper shows a use case running on Apple silicon that’s theoretically valuable:

Who cares if result is right / wrong etc as it will all be different in a year … just interesting to see a test of desktop class hardware go ok.


S&P500 isn’t “the economy” but in the context of talk of a bubble it seems like we’re talking about equities not the whole economy. So let’s just keep taking the short cut …

The top is over performing so concentration is real but it’s not the only growth driver:

The return / valuation concentration prob not as titillating as the PE run up:

True or not true hard to say without better definitions of terms but seems like current profile is not ultra common in history but it’s not a bunch of losers getting diluted out.


The article is clear — lottery offer of a seat in a school which met inclusion criteria. Inclusion criteria are clearly outlined in the supplemental materials which are a single URL away which also include details on the allocation.

Talk of causation anywhere other than the unit of randomization is speculation.


The definition is holistic:

>As shown in Figure S1, we began with a list of 588 public Montessori schools in the United States supplied by the National Center for Montessori in the Public Sector

>[procedural stuff, possibly introducing bias but not definitional]

>Finally, because “Montessori” is not a trademarked term, we checked whether schools met our minimum standards for Montessori inclusion

>- At least 66% of the lead Primary classroom teachers are trained by one of the two most prominent Montessori teacher training organizations, the Association Montessori Internationale (AMI) or the American Montessori Society (AMS). One school was excluded on this basis.

>- No more than two adults, the trained teacher and a non-teaching assistant, in the classroom on a regular basis. No school was excluded on this basis

>- Classrooms are mixed-age, with at least 18 children ranging from 3 to 6 years old. Five schools did not mix ages so were excluded.

>- At least a 2-hour uninterrupted free choice period every day. Five schools were excluded on this basis.

>- Each classroom has at least 80% of the complete set of roughly 150 Montessori Primary materials, and fewer than 5% of the materials available to children in the classroom are not Montessori materials. No school was excluded for failing to meet this criterion. [italics mine, furthermore, holy crap!]

I think one thing that is particularly noticeable is that, while there is definitely some particular form of education being put forward here which is interesting, there is obviously a very "aesthetic" trend as well, because plenty of schools are failing on the practices and the teachers while somehow none are failing the materials. But maybe this is actually just path-dependence in measuring the exclusion per criterion?


the definition in your linked paper is quite self referential


Most studies of hospital resuscitation survival puts it at about a 1/4. Plenty of people survive and have good neurological outcomes lots of people do not [0].

Outside of diagnostically defined cohort it’s a bit of a silly idea as you can attempt on anyone without respect to readily identified odds of success [1] so the what of CPR isn’t readily untangled from the who of it.

Out of hospital is a similar story but with less ability to triage and thus the same pattern in which the fact of CPR [2] is less informative than the underlying problem [3, old but the best study I know of would be interested if someone knows of an update to it given in hospital trend since].
