During the early days of the 2009 H1N1 influenza A pandemic, the popular herbal formula maxingshigan–yinqiaosan was used widely by TCM practitioners to reduce symptoms. (It’s hard to pronounce and spell, so I’ll refer to it as M-Y.) A new study was done to test whether M-Y worked and to compare it to the prescription drug oseltamivir. It showed that M-Y did not work for the purpose it was being used for: it did not reduce symptoms, although it did reduce the duration of one sign, fever, allowing researchers to claim they had proved that it works as well as oseltamivir.
“Oseltamivir Compared With the Chinese Traditional Therapy: Maxingshigan–Yinqiaosan in the Treatment of H1N1 Influenza” by Wang et al. was published in the Annals of Internal Medicine earlier this month. The study was done in China, which is notorious for only publishing positive studies. Even if it were an impeccable study, we would have to wonder if other studies with unfavorable results had been “file-drawered.” It’s not impeccable; it’s seriously peccable.
It was randomized, prospective, and controlled; but not placebo controlled, because they couldn’t figure out how to prepare an adequate placebo control. They considered that including a no treatment group compensated for not using a placebo control, and that objective temperature measurement could be expected to get around any bias. It might not: the nurses who took the temperatures were blinded to the study, but the patients were not. It’s possible that those who knew they were getting M-Y might have believed in it and their bias might have somehow subtly influenced data gathering so that M-Y appeared more equivalent to oseltamivir than it actually was.
There are other problems besides the lack of blinding. (more…)
Althought I and other SBM bloggers have criticized state medical boards for not doing enough to protect patients from physicians who practice pseudoscientific medicine and quackery, they do nonetheless serve a purpose. Moreover, critical to medical boards doing even the limited amount of enforcement that they do is the ability of health care providers or other citizens to submit anonymous complaints against physicians who are not practicing up to the standard of care or who may be in other ways taking advantage of patients. Unfortunately, the other day I found out via one of the that I frequent of a very disturbing case in Kermit, Texas. Two nurses who were dismayed and disturbed by a physician peddling all manner of herbal supplements reported him to the authorities. Now, they are facing jail:
In a stunning display of good ol’ boy idiocy and abuse of prosecutorial discretion, two West Texas nurses have been fired from their jobs and indicted with a third-degree felony carrying potential penalties of two-to-ten years’ imprisonment and a maximum fine of $10,000. Why? Because they exercised a basic tenet of the nurse’s Code of Ethics — the duty to advocate for the health and safety of their patients.
The nurses, in their 50s and both members of the American Nurses Association/Texas Nurses Association, reported concerns about a doctor practicing at Winkler County Memorial Hospital in Kermit. They were unamused by his improperly encouraging patients in the hospital emergency department and in the rural health clinic to buy his own herbal “medicines,” and they thought it improper for him to take hospital supplies to perform a procedure at a patient’s home rather than in the hospital. (The doctor did not succeed, as reportedly he was stopped by the hospital chief of staff.)
How can this be? This is how:
