When Beliefs Replace Evidence: The Trouble with HRT Cessation
By Liz Scherer | Wednesday, May 12th, 2010
By Liz Scherer. A Twitter friend recently asked me about stopping hormone replacement therapy (HRT). It was a question that I hadn’t explored thoroughly although I write about HRT often on my blog. In fact, I had never truly considered the “what now” of the issue, as in, what if you decide to go off hormones or try alternatives after you’ve been on HRT?
Interestingly, when I looked into the issue, the answer seemed to be even less clear-cut than the therapy. In fact, there are no guidelines for stopping HRT. Granted, until the Women’s Health Initiative started to reveal the dangers and risks of HRT, there was no real reason to stop therapy, (although, I’m of the mindset that there’s really no good reason to start HRT).
Fortunately, researchers are finally starting to look into this issue although study findings (which are published in the online edition of Menopause) highlight that the practice of stopping HRT is intuitive and not evidence-based.
So, what did they learn?
Among 438 group practice physicians surveyed, an overwhelming majority believed that women should taper HRT, with most believing that the best strategy was not only to slowly decrease the dose, but also to reduce the number of days HRT was taken per week. However, they had no suggestions with regards to how to taper use of HRT patches, even though the patch is increasingly being recommended and touted as a safe solution to oral hormone therapy. (Notably, like the evidence from this particular study I am talking about, the evidence that shows the safety aspect of the HRT patch is mostly observational, meaning that it is subject to personal bias.)
More interesting, however, was the finding that the majority of the physicians who participated in the study were more strongly influenced by their personal beliefs than by colleagues’ actions or most importantly, by a woman’s preference. In other words, physicians are not asking their patients about what they would like or if they have any thoughts about stopping therapy. More shocking was the fact that only 2% of physicians surveyed relied on actual evidence to stop hormone therapy. Physicians who indicated that they believed that some action should be taken if symptoms returned after stopping hormones overwhelmingly turned to behavioral changes or exercise, not to alternative therapies such as herbs.
In an era of evidence-based medicine and strategies that integrate eastern and western philosophies, why are our physicians relying on their own personal belief systems rather than real facts? Why aren’t they asking their patients how they feel about stopping therapy or if they have fears about symptoms returning and then thoroughly exploring alternatives ? Are these findings in a vacuum or will they be found on a broader basis? Does the problem lie in fact that there are no standards? What’s more, why hasn’t the American Medical Association or American College of Obstetrics & Gynecology devised guidelines for stopping HRT therapy? Why hasn’t the Food & Drug Administration demanded this guidance in labeling?
Finally, why do we continue to play Russian Roulette when it comes to women’s health? Isn’t it time for a change?
Let’s start with HRT. There are a lot of folks out there who continue to espouse the benefits, deny the risks and ignore the facts. Clearly, this story continues to unfold. Unsafe medical practices are even more unsafe when they are not backed by evidence, right? Is HRT the exception? What do you think?
