Mistrust of motives hampers health IT

Republished by Plato

The failure of computerization to launch in health IT is one of the great mysteries of our time. (Image from Wikipedia.)

Computers run our cars, they manage our markets, and increasingly they’re in the medical devices that keep us alive.

But go to any doctor and you’re still going to fill out a paper form. Get referred to a second doctor and you will probably find a second form. And on and on. The cost of managing this paper helps keeps medicine mired in the 20th century.

Having covered  this beat since July, 2007,  I have heard many theories. Complexity, government action, and government inaction are the most common.

But I have found mistrust of motives to be much more prevalent.

The most common motive in the U.S. health care system is the profit motive. Everyone wants to make more money. Doctors, hospitals, device makers, drug makers, and insurers are all united in their search for profit.

But profit is a pretty base motive.

Health care, at its heart, is a struggle between life and death. Passionate people of all sorts are drawn to that struggle. Their motives are often absolute, and in the contradictions between absolutes others’ worthy motives can be seen as evil.

Take drug company marketing for instance.

In every other industry it is common practice for manufacturers to track sales channels. You want to know how retailers are performing and, if they are not, offer them help to get on track.

(Image of junk mail from Wikipedia.)

In medicine doctors are the retailers. Their prescriptions are filled at pharmacies, which break bulk for manufacturers, turning big bottles of powerful pills into little bottles with instructions and warnings.

Customer relationship management (CRM) software mines the data of pharmacists to learn prescribing patterns among the retail outlets, which drug company “detail men” then try to fix.

In a business sense it’s all perfectly innocent. But those are medical records, so in trying to change the patterns of Doctor X, the detail men are trying to change the care of Patients A, B, and C.

Some doctors believe this is interference in their work. But a U.S. Appeals Court has just ruled Vermont can’t stop it.

Ever since Latanya Sweeney and UT-Austin researchers showed, early this year, that identities of Netflix subscribers in “anonymous” records can be teased out using software, privacy advocates have been on the warpath, insisting that any use of data in medical studies is a privacy violation.

But there’s an assumption in these complaints, namely that researchers, drug companies, or any other economic actor cares about your lumbago, or any of your other personal medical conditions.

They don’t. Just because you can track how many tubes of toothpaste remain on a WalMart shelf doesn’t mean you care about the person walking out the front door with a tube in their bag.

Not as an individual. Only as a dollar sign. Junk mail doesn’t come to your door because the sender cares about you. They only want your money. They have identified you as a prospect. They will measure your decision, and those of others, as data.

If WalMart has some idea of your age, income and psychographic profile, that can inform marketing of toothpaste to people who are like you. The only interest is in following the money.

The same thing is true in medical studies, like those released by the Texas State Health Services to medical researchers of all kinds. Just because identities may, in theory, be teased-out of that data through considerable effort, doesn’t make the release of that data a Fourth Amendment violation.

Researchers aren’t interested in individuals, only numbers. They have no motive to know who you are.

There are companies with a motivation to tease identifies out of anonymous data. Employers have one, and insurers have one, because health insurance today is risk-rated. That is, people who are likely to become sick pay more for insurance than those who are presumed to be healthy.

The key to protecting privacy, then, is to eliminate the motive for violating it. It’s not to halt medical or market research with claims which assume false motives on the part of such researchers. To me, that’s Luddism, and I don’t mind saying so.

Unfortunately this distrust of motives can infect me as well as others. Does the fact that privacy advocacy winds up halting the use of medical data make privacy advocates Luddites?  I am wrong to assume so. I apologize for ever having done so, even though that may be the result of such advocacy.

But until everyone in health care deals with their deep-seated mistrust of others’ motives in this business, health IT will continue to struggle uphill.

The Hard Sell

Republished by Plato

Published

on

The prices are low and the panic is high. Is this the time to sell?

If you’ve been around crypto for longer than a couple of months, you’re probably familiar with the feelings that come with your average market-wide correction.

Euphoria fizzling away as that first red candle starts dropping down, down, down. Confidence in a quick recovery giving way to sweaty-palmed anxiety as the correction passes the 10, 20, 30% mark. Is this the big one? We all know what happened on March 13th last year. Finger hovering over the “Sell” button, knowing that if you just pressed it this horrible feeling would go away.

And even worse are the recriminations. How could I have been so blind? How did I let this happen? Why didn’t I sell when the going was good? Will I ever feel joy again?

Unrealised profit and loss

Look, I’m not going to say I told you so, but if there has ever been a market in need of a correction it was the crypto market of the last two months. It wasn’t a question of if your alt was going to do a 50 or 100% day; it was a question of when. Meanwhile, Bitcoin basically tripled its 2017 all-time high over the course of eight weeks, making it (briefly) a trillion dollar asset.

It’s not that bitcoin doesn’t deserve to be in that August club, but more to point out that markets will always revert to the mean, no matter how compelling the background narrative might be. And in the same way that you don’t expect to see an elephant jump over a small apartment block, an asset of bitcoin’s size shouldn’t be tripling in size like it ain’t no thing. Especially not when it’s taken three long, hard years to get back to its previous peak.

Timing is everything

Here’s the thing though: in every other market that humanity has ever created, taking three years to make a new all-time high actually is perfectly reasonable, bordering on suspiciously fast. Investments aren’t supposed to be measured in days or weeks. They’re supposed to take years, if not decades to play out. But the speed, 24/7 relentlessness and hyper-visibility of the crypto markets means it’s very easy to lose sight of the bigger picture. People who bought in at the absolute peak of the last bubble are still up 250% – presuming that they had the patience to hold on for a measly three years.

Nonetheless, selling can produce a real and concrete advantage. Get out near the top and you might be able to buy back in close to the bottom, thereby compounding your gains. (Despite what the people of TikTok Investors would have you believe, this is far harder than it appears.)

More simply though, money is money and when assets are appreciating like crypto assets have recently that can mean getting ahead of your mortgage, or buying a car, or paying for a holiday for your family, or being able to cover rent for the next month. If what you’ve made could make a difference in your life, then it makes complete and total sense to sell some – even if you think the crypto market is going to keep on going up. As the old adage goes, no-one ever went poor from taking profits.

Respect the sell-out

That’s not an invitation or a suggestion to sell it all right now – a good rule of thumb is sell when it feels hard (i.e. on the way up) not when it’s easy (on the way down) – but more to start thinking about what your endgame is. What do you hope to gain from this bull run? How much is enough? And will you be strong enough to start getting out when you reach your target? (Also, on a more prosaic note, what would taking profits mean for your tax?)

These are questions without easy answers, but start planning now and you’re less likely to be swept up in the mania and delirium that marks the real, bloody and unmistakable end of the bull market. And until then? DIAMOND HANDS ENGAGE.

Vitalik proposes solution to link certain layer-two scaling projects

Republished by Plato

Published

on

In an ongoing effort to battle escalating transaction fees while creating a unified ecosystem, Ethereum co-founder Vitalik Buterin has proposed a solution for a particular type of cross-rollup scaling.

The proposal outlines how two protocols using rollups can communicate with each other while maintaining interconnectivity and composability.

Rollups are layer-two solutions that are essentially smart contract networks that process and store transaction data off the main chain. However, there are a number of different rollup types, with each using unique smart contracts such as optimistic and zero-knowledge.

While a number of DeFi projects have deployed layer-two rollups, such as Loopring and Synthetix, the particulars of the various rollups mean projects are unable to communicate to one another directly on layer-two.

Buterin’s proposal assumes that one rollup can process simple transactions whereas the other has full smart contract support. There are already proposals for transfers between two smart contract enabled protocols using rollups.

To explain how the proposal works, Buterin provides the example of a hypothetical exchange intermediary he called ‘Ivan’ — where Ivan has an account ‘IVAN_A’ on rollup A that he fully controls, and also has some funds deposited in a smart contract ‘IVAN_B’ on rollup B.

The smart contract would be programmed to accept “memos” that include additional data from anyone sending to it in order to secure any future transactions. The transactions create a connecting layer that keeps deposits in all these isolated contracts, allowing rollup A to send to rollup B via this layer.

Buterin suggested that the behavior would work as follows;

“Alice sends a transaction to IVAN_A with N coins and a memo ALICE_B. Ivan sends a transaction sending TRADE_VALUE * (1 – fee) coins through IVAN_B to ALICE_B”

He added that the worst-case behavior would be if Ivan does not send coins to ALICE_B as he is expected to.

Addressing the “worst-case” scenario that could arise as a result of using the proposed situation, Buterin emphasized that Alice would still be able to wait until the transaction on rollup A confirms, find some alternate route to getting coins on rollup B to pay fees, and then simply claim the funds herself.

Responding to the proposal, Alon Muroch pointed out that it worked in a similar way to how banks clear transactions:

“That’s very interesting, similar to how banks clear transactions between themselves. Batching assets into separate “accounts” could have limitations, a solution could be just big pools on either ends and fees split pro-rata.”
