Tap tap..is this thing on?
I figured I'd go for one post a decade. A bit late on this one.
Counterspin for Health Care and Health News
...which is why I'm happy when the media do a good job of covering this underappreciated issue. BBC Radio 4 just broadcast an excellent piece on patient safety in the UK. It focuses on alerts issued by the National Patient Safety Agency to local NHS trusts. The alerts are based in part on aggregated reports of errors - or, as some in the US call them, adverse events, to avoid the language of blame - and are meant to help trusts, which have primary responsibility for delivering safe health care, to implement specific procedures aimed at avoiding errors. Trusts are responsible for reporting back on their progress implementing the alerts; there are, evidently, hundreds of trusts that have not yet implemented at least one, and there are a couple more that have not reported back on over 30. A key problem is that there is no national mechanism or authority for enforcing compliance with the alerts, although they are issued at the national level.
Great stuff from the Centre for Evidence-Based Medicine at Oxford, by Dr. Richard Lehman. Now with recipes! Speaking of which, check out my new food blog - in which I figure out how to feed myself in the UK - at Emily Drinking Tea.
Seriously, what took them so long? Their reluctance to address due caution to the chemical really presented an impression that the Agency was beholden to chemical industry interests.
A Guardian article on a new epidemiologic study looking at a class of blood pressure drugs and dementia started out with a headline that was doubly misleading:
Blood pressure drugs can halve risk of dementiaFirst of all, this may just be my own reading problem, but when I first saw the word "halve" my brain saw "have" and interpreted it to mean that the drugs increase risk of dementia. But when I slowed down and re-read it, I was not much happier, because I've developed this intellectual/editorial tic, a tendency to notice and then question statements that imply causation. The Guardian lead reiterated the causal language:
Millions of older people who take drugs for high blood pressure or heart problems can more than halve their risk of developing Alzheimer's disease and dementia, according to research.For the headline and lead to be supportable, there would have to be a clinical trial randomly assigning people (a lot of them) to get ARB drugs, or not. It seemed unlikely, and in fact, it wasn't the case. Here is the original article from BMJ. Sure enough, right in the article's title, it says that it's a prospective cohort study - a very good one, I'm sure, but designed to look at associations, but not causation. And here's the conclusion of the research article:
Angiotensin receptor blockers are associated with a significant reduction in the incidence and progression of Alzheimer’s disease and dementia compared with angiotensin converting enzyme inhibitors or other cardiovascular drugs in a predominantly male population.Wordy, but - again - in terms of "association" not an active, causal verb phrase like "cuts risk by half."
The whole Facebook bra-color thing. It started out as a silly meme, someone apparently tried to legitimize it by attaching it to breast cancer awareness, breast cancer groups tried to weigh in, and the Washington Post wrote up the whole kerfuffle.
The first thing I discovered as I waded out into the relevant [breast cancer] sites is that not everyone views the disease with horror and dread. Instead, the appropriate attitude is upbeat and even eagerly acquisitive. There is, I found, a significant market for all things breast cancer-related. You can dress in pink-beribboned sweatshirts, denim shirts, pyjamas, lingerie, aprons, shoelaces and socks; accessorise with pink rhinestone brooches, scarves, caps, earrings and bracelets; and brighten up your home with breast cancer candles, coffee mugs, wind chimes and night-lights. "Awareness" beats secrecy and stigma, of course, but I couldn't help noticing that the existential space in which a friend had earnestly advised me to "confront [my] mortality" bore a striking resemblance to a shopping centre.
According to the Washington Post, Maine is considering adding a warning about cancer risk to cell-phones. A state legislator claims that there are "numerous studies" to support such a risk. To be fair, I'm not really current with the literature, but I do wonder: do cell phones also come with a warning about risks of crashing your car?
