two medical screening articles, one dippy, one interesting

I'm sure their numbers are right, and I'll even stipulate without further investigation that their methods were no worse than average.

But come on. If you are a frail 80+ year old woman who no one is going to operate on anyway, and who already has a DNR, do you really need to be subjected to regular mammograms? This is just asinine.


They're just trying to drum up more business.

"This study suggests that mammography benefits may have no age limit and that women should consider being screened on a regular basis, even into their 80s and possibly 90s, depending on their current health status," study chief Dr. Brian D. Badgwell, MD, of the University of Texas M.D. Anderson Cancer Center said in a written statement.

Well, Dr. Badgwell, you go out and have some sensitive bit squished to a point where you'd just about rather die than continue. Regularly. As an 80 year old. And tell me that torture does any real good for anyone.

The other article(s) is about Ritalin and related stimulant drugs to treat ADHD and similar in children. As one might expect, stimulant drugs + heart problems = bad.


"Children should be screened for heart problems with an electrocardiogram before getting drugs like Ritalin to treat hyperactivity and attention-deficit disorder, the American Heart Association recommended Monday."

At least some of the coverage is doing a good job of pointing out the (in)obvious.

(1) Screening costs something (apparently $100 or so per ECG)
(2) False positives will create a cascade of more intrusive, expensive, possibly more dangerous tests that are emotionally extremely stressful for the patient and family.
(3) ECG screen may let enough cases through that screening ultimately has no net benefit.

No net benefit can happen several ways. The "cost" of the program may exceed the "value" of the patients saved. That's kind of yucky. But also, the added deaths due to additional unnecessary testing in the resulting false positive cascade (yes, virginia, people _do_ die from tests!) could conceivably equal or exceed the hypothetically avoided deaths from successful screening. And there's a chance this won't actually save anyone.
