NHS hit by unforeseen Earth tilt

A critical government service has to be prepared for all foreseeable contingencies. But sometimes the unpredictable occurs, and bureaucrats can fall into panic.

A tilt in the Earth’s axis that no one could have foreseen is apparently causing daylight to grow shorter in northern latitudes and temperatures to drop, leading to an increase in communicable diseases and accidents that threatens to overwhelm NHS emergency services. Or, in other words,

Disclosure of NHS England’s attempt to impose a detailed series of duties on hospitals comes amid claims by senior insiders that its leadership is in a state of panic over winter.

The people let down the NHS

I saw this headline in the Daily Mail yesterday:

Pity the poor NHS. Doing its job perfectly, but being cruelly let down by the shiftless population. To paraphrase Bertolt Brecht, perhaps it would be better were the NHS to carry out a root-and-branch reform of the British public. Eliminate waste. Get rid of the dead wood.

NHS wants you! (to spread the varicella virus)

I’ve long wondered why children in Britain generally don’t get the chickenpox vaccine. In an article describing a move by drugstores to offer the vaccine for a substantial fee, the BBC quotes the NHS:

The NHS said a chickenpox vaccine is not offered as part of routine immunisations as it would leave unvaccinated children more susceptible to contracting the virus as an adult.

There could also be a significant increase in shingles cases as being exposed to infected children boosts immunity to this.

This is like the cracked-mirror reflection of the usual herd-immunity argument for why, even if you don’t want vaccines for yourself or your children, you have a civic obligation to make yourself immune to avoid transmitting the virus to others. Here they say that children have a duty to suffer with an unpleasant disease, so that they can serve as walking virus reservoirs that will more efficiently infect other children, and boost the immunity of adults.

I suppose there’s a cost-benefit analysis somewhere that shows this is the cheapest approach. And I’d bet that the cost of children’s discomfort is set at zero.

“A triumph of personal bias over research”

The Guardian reports on a new research study that finds the overstretching of the NHS — particularly in the winter — has caused about 30,000 excess deaths in 2015. The government’s response is practically Trumpian:

A DH spokesman described the study as “a triumph of personal bias over research”. He added: “Every year there is significant variation in reported excess deaths, and in the year following this study they fell by nearly 20,000, undermining any link between pressure on the NHS and the number of deaths. Moreover, to blame an increase in a single year on ‘cuts’ to the NHS budget is arithmetically impossible given that budget rose by almost £15bn between 2009-10 and 2014-15.”

Demeaning experts who bring unpleasant news is the primary tactic. (more…)

CDC works toward the president

Dem Führer entgegenarbeiten — Working toward the Leader — was one of the most important neologisms of the early Third Reich. No one really knew what Hitler wanted to do — not even Hitler himself — and the organs of state were in turmoil, certainly incapable of providing rapid guidance at the local level to the government’s plans. So everyone’s obligation was to surmise what the Führer’s ultimate objectives were, and work toward accomplishing it, without needing specific instructions.

Compare that to these recent decisions of the completely apolitical Centers for Disease Control and Prevention:

CDC abruptly cancels long-planned conference on climate change and health

The Climate and Health Summit, which had been in the works for months, was intended as a chance for public health officials around the country to learn more about the mounting evidence of the risks to human health posed by the changing climate. But CDC officials abruptly canceled the conference before President Trump’s inauguration, sending a terse email on Jan. 9 to those who had been scheduled to speak at the event. The message did not explain the reason behind the decision.

CDC Indefinitely Postponed LGBT Youth Health Summit After Election

To be fair, the reason seems to be that they needed the resources to focus on their conference on disease transmission by refugees and illegal immigrants.

 

Warnings

Suppose your football coach exhorts the team with all the great coach clichés: “We win or lose together”, “There’s no I in ‘Team'”, maybe “We can still win if we pull together and give 110 percent in the second half”. Would anyone say this was a “warning”? But when Angela Merkel says Europe needs to work together to deal with the current influx of migrants, we get this headline in the Guardian:

It reminds me of the peculiar set of mandatory texts that were introduced for cigarette packets in the US in 1981: Among the warnings of carbon monoxide and foetal injury was this one:

SURGEON GENERAL’S WARNING: Quitting Smoking Now Greatly Reduces Serious Risks to Your Health.

“Greatly reduces serious risks to your health” doesn’t sound like a warning to me.

I didn’t even know it was a strategy…

Headline in today’s Times:

Obesity Strategy ‘is Failing’

A walk in the park

A land without serious problems, Australia is worrying about the pampered dogs of a pampered movie star, who were smuggled in on a private jet without proper medical screening. Agriculture minister William Joyce has declared that the dogs must be returned to California forthwith or be put down. These dogs are of particular concern because they “come from a country that has rabies.”

The reason you can walk through a park in Brisbane and not sort of have in the back of your mind – what happens if a rabid dog comes out and bites me or bites my kid – is because we’ve kept that disease out.

Obviously he is not aware that Californians always put on their bite-proof body armour to protect themselves when they leave their fortified bunkers. Rabies is pretty much all anyone thinks about when they walk through a park in San Francisco.

Risk categories and e-cigarettes

I’ve been reading Kate Fox’s celebrated Watching the English, which is sort of a pop-sociological treatise on English customs, but somewhat hard to take for all its flattering the English in all the myths they cherish about themselves — including their supposed modesty and inability to accept compliments. (I was particularly astonished by her description of the supposedly considerate English drivers. Perhaps they treat other drivers with more respect than they can spare for pedestrians.)

Anyway, since I am intrigued by the way “e-cigarettes” — devices for inhaling an addictive drug — have managed to float free from drug regulations, not to mention the prohibition that usually gets slapped onto designer drugs, as well as from their association with increasingly illicit tobacco. Fox is a huge fan, and can’t understand how anyone could object:

These clever devices are a sort of glorified version of nicotine inhalators, which look and feel rather more like a real cigarette, and emit a totally harmless, odourless steam or vapour that looks a bit like smoke. Many people are now accustomed to seeing these electronic cigarettes, and know that they are harmless…

Some people, however, do not instantly grasp this… and I have been conducting informal cross-cultural research on their reactions. In England, there are the usual raised eyebrows, frowns, pursed lips, tuts and mutters… But in all the years that I have been using these e-cigarettes on public transport and in restaurants, pubs and other public places where smoking is banned, only one English person has ever actually ‘confronted’ me about it…

In almost all countries, this disapproval quickly turns to friendly laughter, or curiosity, once I have explained that my ‘cigarette’ is an innocuous electronic device. The only exception I have found so far is the US, where some people seem to object almost as much to completely risk-free e-cigs as they do to the real thing — an irrational reaction that brings to mind my favourite definition of Puritanism: ‘The haunting fear that someone, somewhere, may be having fun.’

(Mencken’s definition was actually “that someone, somewhere, may be happy”.) There’s a fascinating number of words about risk here: odourless, harmless [twice], innocuous, completely risk-free, irrational reaction. It brings to my mind the ridicule heaped upon the killjoys who suggested in the 1980s and 1990s that something as innocuous as sidestream tobacco smoke could harm people’s health. Now everyone accepts that sidestream smoke is highly toxic, but the completely unregulated mixtures of chemicals spewed out by e-cigarettes are supposed to be harmless. On the basis of advertising copy, so far as I can see.

In contrast to the anthropologist Kate Fox, mere epidemiologists do not describe the second-hand exposure to e-cigarette vapour as “completely risk-free”. Instead, they say things like

Schober et al. measured indoor pollution from 3 people using e-cigarettes over a 2-hour period in a realistic environment modeled on a café. They found elevated nicotine, 1,2-propanediol, glycerin, aluminum, and 7 polycyclic aromatic hydrocarbons classified as probable carcinogens by the International Agency for Research on Cancer in the room air.[…]

on average, bystanders would be exposed to nicotine but at levels 1/10th that of cigarette smoke (e-cigarette aerosol, 3.32±2.49 μg/m3; cigarette smoke, 31.60±6.91 μg/m3; P=0.008). Both e-cigarette aerosol and cigarette smoke contained fine particles …

So e-cigarette vapour contains known carcinogens and the addictive drug nicotine. It is known that persistent low-level exposure to nicotine can provoke nicotine dependence, particularly in adolescents, or predispose them to other drug addiction.

Some people choose to take that drug recreationally, and I don’t object to them having that right. But why would a scientist disparage other people’s unwillingness to accept these risks to support her habit as “an irrational reaction”?

Of course, I know why. It’s one of the standard clichés about scientists, that they use the pose of rationality to claim an authority that they have not earned, to pretend that their private caprices are facts. It is unprofessional, and it undermines the whole enterprise of science.

Building confidence in public health

The NHS informs concerned parents about vaccines:

The 4-in-1 pre-school booster is very safe. Before it was granted a licence, the safety, quality and effectiveness of the pre-school vaccine, like all vaccines, was thoroughly tested. It does not contain thiosermal (mercury).

A lot of parents are (probably unnecessarily) worried about thiomersal in vaccines. The reassurance from NHS would probably be more persuasive if they knew how to spell it. (Thiomersal is, confusingly, called “thimerosal” in the US, but not “thiosermal”.)
