I'm not sure that the line is blurry...
> I look forward to more science showing that doctors now flee to medical journals to look up which drugs to use instead of drug dinners. Won't happen.
I look forward to the day that the major scientific findings are presented to doctors and consumers alike in a way that is comprehensive and accessible.
I'm greatly concerned about the impact of advertising on medical decisions. If it were the case that the best products sold more then I wouldn't have a problem with that. What concerns me is that the medical advertising doesn't make scientifically reputable claims about their products. They willfully mislead because they are more focused on making sales than patient welfare. They are a business primarily.
> Advertising does not imply an a-rational decision.
In 'critical reasoning' courses it is common to distinguish between rational means of persuasion (e.g., based on evidence and arguments) and a-rational or irrational means of persuasion (e.g., rhetorical devises, appeals to emotion, fallacies in reasoning (appeal to illegitimate authority like models singers and actresses, base rate fallacy etc etc etc).
There is a science behind advertising (psychologists get paid a bomb to find out how to make products sell) and the most effective means of persuasion aren't the rational ones. People are often surprised to find that product placement has a significant impact on peoples purchasing decisions in supermarkets. People are often surprised to find that they are purchasing a product in bulk (with 20% extra free!!!) when it is actually cheaper (on occasion) to buy 2 boxes of the smaller which is equivalent in the amount of product. People are often surprised to find how much they are susceptible to 'exposure effects' of a brand name being more familiar so that people feel more psychologically comfortable with that brand. Not all of these apply... But maybe there is no such thing as a free pen ;-)
As such it is important to counter the effects of advertising (one would have thought) to both lend better credibility to psychiatry and to medicine (so prescribing practices actually are based in evidence based medicine rather than on sampling errors, base rate fallacies, who sponsors lunches etc) Also to ensure the best possible standard of health care.
New Zealand (or possibly Australia - I forget) trialled doing without direct to consumer advertising (clinicians still weren't spared advertising, however). There were interesting findings - more people would go to the doctor for minor ailments if there was an advertising campaign to the consumer (might be that we are picking up on more cases which is good, might be that the ailments weren't anywhere near as problematic as the side effects some experienced from the medication which was bad, might be that the conditions became overdiagnosed as patients weren't happy unless they were prescribed the brand they asked for).
New Zealand (I think) changed. For political reasons.
I guess there could be two options:
1) Have stricter laws about false advertising and raise the standard of the claims that the advertisements are allowed to make. That won't help the consumer much with respect to willfully misleading statistics, however. This also won't help with familiarity effects and positive associations of drug x and puppies happy beautiful people and sunny meadows.
2) Restrict (or ban) advertising altogether.
> I'm a big research-reader. I don't disagree that decisions should be based (most of the time) in science. However, there is no research (ironically) that demonstrates that the government regulating an industry based on their perceived ethics results in better patient outcome, decreased adverse events, or cost-savings.
The research done in New Zealand might be a place to start. That was just a ban on DTC advertising and not pharma advertising across the board, however.
Who do you think are going to fund those studies? Pharma?
That is another problem with science in medicine / psychiatry... While pharma sponsors the studies / provides the samples to approved investigations / hires the people to conduct the trials etc... We simply don't have access to the same quality (relatively objective) scientific studies as other fields such as physics and (non-medical) chemistry and biology...
