Dazed and Confused – Revisited

Posted by Liz on May 31, 2010 in herbal medicine, menopause | 2 comments

Two years ago i wrote a post about the confusion surrounding therapies, effectiveness, and discerning right from wrong when it comes to clinical trials. Herbal and integrative therapies are perfect examples of the grey areas; many trials have not incorporated some of the most important tenets supporting the use of these strategies, most important of which is individualization. Hence, I wanted to share the post with you again, and hopefully, spark some dialogue that might lead to improvements in how we study and write about the therapies that are offered to patients.

A gal pal mentioned to me this morning that she often feels so confused about study findings proving or disproving the value of certain medications or herbs that she often just throws up her hands and does nothing. Many of us are as dazed and confused as she is so that I thought that a few key points about clinical studies might help.

Mike Clarke from the School of Nursing and Midwifery at Trinity College in Dublin wrote a great article a few years ago about the need to standardize results of studies for a specific disease ( in this case, rheumatoid arthritis). He defined the problem as follows:

“Every year, millions of journal articles are added to the tens of millions that already exist in the health literature, and tens of millions of web pages are added to the hundreds of millions currently available. Within these, there are many tens of thousands of research studies which might provide the evidence needed to make well-informed decisions about healthcare. The task of working through all this material is overwhelming enough without then finding the studies of relevance to the decision you wish to make…”

So what do you do? A few key points:

• Consider that every study has the potential for bias. Perhaps researchers are using 7 instruments to measure depression and only highlight findings from 3 of these in order to preserve the most positive or significant results. Clearly, the reader is being led towards certain outcomes and away from others.
• Study designs, types of patients studied, age of patients studied, gender, you name, can differ so it’s difficult, if not impossible to draw definitive conclusions when comparing results of one to another.
• Another issue of great interest to practitioner of Western medicine is whether or not a study is controlled. This means that two groups are compared that are identical in every way except one group is given an experimental treatment and the other, a placebo or standardized treatment. Note that often, real world conditions are often recreated rather than conducted in a real world setting and many studies are not controlled, meaning that the science behind the findings is questionable.
• Alternative and complementary medicines are still incompletely understood among many practitioners of Western medicine. What’s more, products are not regulated as carefully as medicinal agents and manufacturing practices vary. Consequently, studies of these agents or modalities are often inconclusive. And of course, often underfunded and under-appreciated.

No wonder we all feel so dazed and confused!

I’ve written several times about the importance of consulting a practitioner or medical expert before embarking on any regimen for perimenopausal symptoms. Even if you only see someone once, at least that dialogue may be useful for defining a regimen that may work best for you and what you’re going through. And if you live off the beaten track without access toa good practitioner, well then excellent resources like Medline or the American Botanical Council may be be of help in discerning what’s what.

The short answer is that there are no short answers. But with careful guidance and a bit of prudence, you may just be able see the light and smooth out the bumps on this rollercoaster ride we’re all on.
