From Dogs Naturally: Evidenced Based Medicine 1 Attachment(s) {{{ This article was PMd to me and the member asked that I post it here, as she was not comfortable posting this article due to its potentially controversial content. }}} Link to article Evidence Based Veterinary Medicine Many of our posts, articles and authors seem to irritate vets and pet owners who are firmly entrenched in traditional medicine. By and large, the most common challenge they use against us is, “where are the scientific studies backing up your claims?” It’s paradoxical that holistic medicine is unfairly held to a higher burden of proof than mainstream medicine. Do the vets and pet owners who accuse us of promoting medicine that lacks ‘scientific validity’ know that the majority of conventional drugs have an unknown mechanism of action? One Golden Example Some interesting examples from conventional human medicine include the 1950’s use of tetracycline (an antibiotic) in the treatment of rheumatoid arthritis on the theory that it was caused by infectious agents. This was discontinued when rheumatoid arthritis came to be thought of as an autoimmune disease and the standard treatment changed to gold compounds despite their mechanism of action being largely unknown. The mechanism of action for acetylsalicylic acid, a compound found naturally in white willow bark, and better known as Aspirin, was not discovered until 1971, although it had been available commercially and prescribed since about 1899. The mechanism of action is in fact unknown for large numbers of commonly prescribed drugs including statins, most psychotropic /psychiatric drugs like Lithium, acetaminophen and Lysodren (a common chemotherapy drug) and general anaesthetics. Would it then make sense to stop using those on surgical patients? And this is by no means a comprehensive list. It’s very common in the pharmaceutical industry for drugs to be in vogue for a particular condition, for a certain period of time and to later be found as useless, ineffective, dangerous, or more useful for some other condition than for which they were created. Ironically, we don’t have that problem with homeopathic remedies or medicinal herbs. The same ones that worked 200 years ago still work today. On the same conditions. Sadly, “evidence based medicine”, although an excellent concept, has been corrupted into a buzzword used to discredit the results of raw feeding, homeopathy and other so-called alternative health care methods. “Evidence based” means that data from randomized controlled studies provides certainty about whether a treatment will work and is safe. The reality is 66% of the treatment procedures and drugs that are commonly used in conventional medicine have no or little evidence to recommend them (British Medical Journal, 2007). Many procedures have serious complications and many drugs cause difficult and unwanted effects. It is these issues that drive pet owners toward less harmful and health promoting approaches in the first place. Below is the breakdown of clinical evidence for 2,500 common medical treatments from the study in the British Medical Journal.* {{{ SEE CHART ATTACHED BELOW }}} That’s a big grey area on the left, isn’t it? Add “unlikely,” “likely to be ineffective or harmful,” and “trade-off,” and that’s two-thirds of conventional medical treatments that are dubious. The situation is likely worse in animal medicine. Often, human drugs and medications that have failed human trials are subsequently solicited to the pet market. In addition, there is no formal requirement for reporting adverse reactions to pharmaceuticals in veterinary medicine. The next time somebody defends conventional medicine by asking us for “scientific validity”, we might ask them the same question. |

First, this article creates a "straw man" type of argument. A straw man argument is defined as: "a common form of argument and is an informal fallacy based on false representation of an opponent's argument. To be successful, a straw man argument requires that the audience be ignorant or uninformed of the original argument." (From Straw man - Wikipedia, the free encyclopedia) This article gives a false definition of "evidence based medicine." The actual definition of evidence based medicine is "the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research." (From Evidence based medicine: what it is and what it isn't | The BMJ) In other words, it is medicine that works in a practical sense on real patients. If a treatment doesn't work, it isn't evidence based medicine. This makes the graph accompanying the article rather puzzling and unhelpful. It doesn't help that the most important links embedded in the article don't work, and it's not possible to track down where that graph actually came from, or what it was meant to demonstrate. Clearly, based on what evidence based medicine actually is, statements like the following aren't relevant: "The mechanism of action is in fact unknown for large numbers of commonly prescribed drugs including statins, most psychotropic /psychiatric drugs like Lithium, acetaminophen and Lysodren (a common chemotherapy drug) and general anaesthetics. Would it then make sense to stop using those on surgical patients?" This isn't evidence based medicine either: "Often, human drugs and medications that have failed human trials are subsequently solicited to the pet market. In addition, there is no formal requirement for reporting adverse reactions to pharmaceuticals in veterinary medicine." The original article DOES link to the following website on homeopathic medicine, which I suppose is the point of this article: - Home Clearly, homeopathic medicine is subject to the same rules as evidence based medicine: Does it work? I can't answer that question, but I will simply state that this article doesn't help explain what evidence based medicine is, and whether or not homeopathic medicine works. |
Since I met the character limit on the previous post, I couldn't give the more expanded definition of evidence based medicine. Here it is: Evidence-based medicine has been defined by its proponents as the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. In this definition, the practice of evidence-based medicine means integrating individual clinical expertise with a critical appraisal of the best available external clinical evidence from systematic research. By individual clinical expertise is meant the proficiency and judgment that individual clinicians acquire through clinical experience and clinical practice. Increased expertise is reflected in many ways, but especially in more effective and efficient diagnosis and in the more thoughtful identification and compassionate use of individual patients' predicaments, rights, and preferences in making clinical decisions about their care. By best available external clinical evidence is meant clinically relevant research, often from the basic sciences of medicine, but especially from patient-centered clinical research into the accuracy and precision of diagnostic tests (including the clinical examination), the power of prognostic factors, and the efficacy and safety of therapeutic, rehabilitative, and preventive regimens. The practice of evidence-based medicine is a process of lifelong, self-directed learning in which caring for one's own patients creates the need for clinically important information about diagnosis, prognosis, therapy, and other clinical and health care issues, and in which its practitioners: 1. Convert these information needs into answerable questions. 2. Track down, with maximum efficiency, the best evidence with which to answer them (and making increasing use of secondary sources of the best evidence). Examples of such secondary sources are the Cochrane Library and journals of critically appraised clinical articles such as ACP Journal Club and Evidence-Based Medicine. 3. Critically appraise that evidence for its validity (closeness to the truth) and usefulness (clinical applicability). 4. Integrate the appraisal with clinical expertise and apply the results in clinical practice. 5. Evaluate one's own performance. The rest of the article (probably behind paywall) is here: Evidence-based Medicine - Encyclopedia of Biostatistics - Sackett - Wiley Online Library Nothing about quadruple-blind peer-reviewed studies conducted in the darkest recesses of pharmaceutical company basements here. Rather than erecting a bogeyman, I think it's important to know what evidence based medicine actually is. |
Very thoughtful response, Phil. I know for me, it comes down to one thing....my dogs will never be guinea pigs. I want well thought out and tried and true methods of treatments for them. Ann, no disrespect intended here, but I cannot think that you would believe this article is valid. I realize you did it for a member as you put that disclaimer on it. Yes, I realize you like all sides expressed, but you and I have the same professional background and I seirously doubt you bought this article. I would not post it for anyone, even at a price! I can see why that member would be uncomfortable posting it...he/she already knows it is controversial. That alone should raise a red flag to them!! I just wish people would realize that no one is just arbitrarily bashing them for their posts of these things. People try so hard to make others understand that much of this is simply not good information; and I know that I like to let people know for their good and the good of their pets. It scares me that things like this are so readily just accepted as gospel. |
Thank you Phil for the honest clarification of the article that was presented. |

Thanks Phil for posting this more complete definition of what is meant by evidence based medicine. It is interesting to take note of the fact that clinical personal experience is highly factored into an evidenced based approach. There is nothing in the above definition that precludes naturopathic or homeopathic doctors from practising an evidence based approach. With the glaring exception of the fact that the body of scientific studies for herbal remedies (of one nature or another has not been built). In my reading of the article below this person was not providing a definition of Evidence Based Veterinary Medicine in its totality - but as asserted in the first paragragh speaking to a specific question that they get quite commonly - ergo - where are the studies backing up your claims? And I have no doubt that is a question they often get! Certainly one I would ask. I believe it is a common conception (perhaps misconception) that there are scientific studies in traditional medicine to back up every treatment plan a vet or an MD makes. This article is pointing out the fact that this is patently not so. Is this assertion valid? IDK. But common sense tells me it is so. The author focussed on mechanism of action being unknown for many drugs out there. Is this a true statement of fact? IDK - How important is it to know the mechanism of action before prescribing a drug? Marketing it? Or is it more important to know that it works on some of the ppl some of the time - and if over time it is shown to be ineffective for condition a/b/c then you stop prescribing it. I have a question for you Phil - I have heard recently that Canada and the USA signed an international agreement years ago - 15 or more years ago - signed an accord that said - the funders of the research *own the research* - and that includes publishing or not the results of the study. As of yet I have not been able to confirm that assertion. If true that is very disturbing to me. Homeopathic medicine has a huge body of clinical experience available to the doctors of said medicine. At least that is my understanding. I how-ever agree that this article whilst pointing out some of the short-comings of Western medicine does nothing to advance the validity of homeopathic or naturopathic discipline.

One of my favorite examples of mixing homeopathic with traditional medicine is one of my former pups who has since left me due to renal failure. He came to me at the age of 8 with horrible skin issues. For those who have seen these photos before, I apologize; but I think he is such an excellent example ... Index of /cody (the first two links are his before and after) Cody had bacterial and fungal infections. My vet prescribed an antibiotic for the bacterial infection but not an anti fungal. She told me to bathe him 3 times/week and then rinse him in 50/50 warm vinegar and water. I remember questioning her because I felt he should have an anti fungal, but she insisted it would work and felt it was better than to use the medication. It was amazing! He started to respond after the first week...and I so remember when he started growing hair on his little bare chest. I remember telling him that he was going through puberty. LOL Since that day/experience I have had many pups with allergy issues who have had fungal infections and to this day I have never given an anti fungal. I had a member here who once told me that tea bags cure staph infections ... to me that is way off the beaten path. We know for a fact that antibiotics cure bacterial infections. Maybe if you get to something early, you can get away with homeopathic but certainly not once an infection has set in/taken hold. Just one example...but I think it is a good one especially since the photos are really a great overall picture of it. |

No, the mechanism of action of MOST drugs is known--the article was pointing out a few examples of drugs for which the mechanism was not known at the time they were developed. The most important question is "does it work?" but obviously it helps if they know the mechanism, because it makes it easier to develop more useful drugs, as well as to know the interactions with other drugs that might result in side effects. The reason they were making this point is that the mechanism of homeopathic medicine is not understood, either. And that's okay, IF there is a body of evidence that shows that it works. Mechanisms can be worked out later. Quote:
My next research project :). I will see if I can find out for you. My understanding is that if a drug is going to be marketed, they HAVE to publish the data that proves that it works, or make it available to the regulatory agencies (not all data is worthy of publication). The manufacturing techniques, though, are trade secrets, and they don't have to reveal those. They do have to prove safety and effectiveness of the final product, though. Quote:

I almost bit my own hand off trying to not respond so thank you for taking the initiative! Yes, it is important to understand how/if/why the medicine is targeting the appropriate pathways and networks and this is important in pathological and psychological medicines. Even if it is not immediately known, this is always investigated once the efficacy has been established. It would be unethical, otherwise, to recommend or market the medication ... Yes, I know that after the fact a lot of meds are recalled or there is a development in the efficacy or lack thereof but that just goes to show that research is ongoing, even for 'approved' medicines and that we continually have to readjust our expectations and recommendations re: certain meds. Okay, my mouth is now empty of hand. |
I also want to add that I find it very sad that someone was 'afraid' to post their thoughts re: homeopathic remedies. Although I think this particular link is not a good representation of the pros of the approach, there are well-known instances where homeopathic remedies are effective. For example, the neurological condition 'restless legs syndrome' is often treated with Parkinson disease medication. This is because it is thought that dopamine levels = restless leg symptoms. However, Parkinson disease medication targets multiple pathways which may not be relevant to someone not suffering from the condition. In addition, the medication can cause unpleasant hallucinatory effects! Therefore, MD's often suggest (as a first step of treatment) that patients consider putting a bar of soap under their mattress at night. There are numerous reports that this is effective at minimizing restless leg symptoms. So, in the first example, you have evidence based medicine i.e. we know the pros and cons of using this medication for restless legs, it's limitations, how it works, etc. In the second example, we have word of mouth or 'folk' medicine which thousands of people swear by. One is not better than the other if they equate to a desirable outcome for the individual concerned. I think a bridge needs to be drawn between the medicinal community and the homeopathic community. As someone said above, smear campaigns will only result in polarization which is not good for either side. All remedies should be embraced and strengths and limitations analyzed and discussed honestly. I find it concerning the level of mistrust that is shown towards medicine despite all it has done to allow us and our dogs to overcome so many ailments and conditions. It would be nice if we weren't 'sided' so that we could consider the good and bad for all treatment/curative/preventative methods for various conditions. One final thing, medicines have to be shown to be more effective than placebos for the targeted condition or they are disregarded and not approved. I'm not sure how many know that! |
People who are afraid to post things need to ask themselves why they are afraid. Is it because they cannot handle that people will disagree? If so, then perhaps they should not post things like this. Once you believe in something, it should not matter that others do not. I know that for some time here on the topic of dog food there were SO many people bashing some of the foods I used that I simply didn't want to jump into the fray. Why? Who knows really...I asked myself that question a few times. I still hesitate to post some of my thoughts at times ... shrug....you just have to believe in what you are saying AND IMO be willing to allow others to post their opinions. Who knows...maybe you will learn something that you believed is not so? Maybe they will as well. I have yet to have anyone show me a reason that I felt valid enough for me to change what I feed my pups but I suppose it could happen. The bottom line IMO is people who are just unwilling to accept that others will have a different opinion...and they take it personal. I think that most of the posters on this forum are not being "personal" in their posts. and...honestly, if someone is, it is their issue. There is a report button though.....but just merely diagreeing is not reportable. We all need to put on our big girl panties and trudge along...each of us is entitled to our opinions. |
I think many do know about placebos - what is much more interesting to me - is where is the research on the placebo effect? Many %'s have been quoted on various studies - anywhere from 5 to15% or more. If folks believe that this drug (which they are not getting will cure them or help them) and they are helped or cured - Wow! why not try to find out how that happened. Is it possible we humans have the innate ability to cure ourselves of what ails us? If so - that would be the most incredible advance in knowledge so far. Sounds like Sci Fi right? Well so was walking on the moon - which was written about by SciFi writers 40yrs or so before it actually happened. |

IDKW this particular poster was hesitant to post a controversial article - or at least one she believed would be. Maybe to avoid being ridiculed and made to feel stupid by other members here. To be denigrated for merely finding an article interesting and informative to her. And I agree with Misty - it is sad that others here are hesitant to post about some things. In essence what we have talked about is this articles' short-comings. She now can read our comments - learn some more - about how others viewed the article and maybe go away with a more critical mindset when pursuing other articles of this genre. That is a win win for her. |

Some people are not as articulate as others and so feel intimidated by others ideas which are presented scientifically and, in some ways, arrogantly as compared to lay person's opinions. This phenomenon is known as 'imbalance of power' and it is something clinicians have to be aware of when discussing things with clients. Feeling like your opinions are not justified in the face of someone with different educational attainment, background, profession etc is a very real and frightening experience. Not taking this into consideration can severely damage a patient/clinician relationship as well as peer-to-peer friendships and other dyadic relationships. So, whilst you seem well grounded in your ability to express your opinion even in the face of adversity, this is almost impossible for some who are afraid of reprisals (real or imagined) like judgment or scorn. Socio-cultural phenomena is almost always complex and is in no way uni-directional, which is to say, there is more than just cause and effect to various behaviors. So, people are not necessarily afraid because of you or your opinions, their histories and their own experiences (within this forum and elsewhere) go into what makes them afraid so it would be very hard, therefore, to expect that they just 'get over it'. Therefore, it is up to us who do not have such fears (or have them to a lesser extent), to show that we have nothing to offer other than education and support re: various opinions. Anything else can be construed as damaging and result in this dichotomy we are seeing here i.e. the 'science' clique vs 'everyone else'. |

One published research study on how the placebo effect works |

NAFTA - Chapter 17 NAFTA's Intellectual Property Provisions | Dr Dobb's I am pretty certain that the portion you are referring to is the Trade Secrets section, which would protect manufacturing techniques. I think that's pretty reasonable. I couldn't find anything about funders of research owning the research, but I think that's a reasonable intellectual property right. (For instance, when I worked at Iowa State University, if I patented something, the patent was owned by Iowa State University.) HOWEVER, in the case of medicines and therapies, they are still required to prove that medicines and therapies that are being marketed are safe and effective, and to provide information about side effects. Those are basic food and drug laws. Here is the analysis of the Trade Secrets section of NAFTA: On December 17, 1992 the leaders of the United States, Mexico, and Canada signed the North American Free Trade Agreement (NAFTA), which contains the most comprehensive multilateral intellectual property agreement ever concluded. NAFTA was initiated on January 1, 1994 and is expected to create the largest free trade zone in the world with an anticipated gross national product totaling over $6 trillion. NAFTA's intellectual property provisions create the highest legal standards for protection and enforcement of intellectual property ever negotiated. NAFTA provides companies wishing to do business in Canada, Mexico, and the U.S. (and future NAFTA member countries) with the means not only to protect their intellectual property, but also with better laws for doing business in general. Prior to NAFTA, U.S., Canada, and Mexican standards for the protection and enforcement of intellectual property rights differed and inhibited the willingness of companies to risk business ventures in foreign countries. [..] NAFTA's scope of intellectual property protection includes copyright, trademarks, trade secrets, and patents. In addition, NAFTA also protects semiconductors, geographical indications, satellite broadcast signals, industrial designs, and sound recordings. NAFTA's benefits are not limited to those industries whose primary goods rely on intellectual property rights protections, but rather for any company that seeks to protect its trademarks, logos, and/or trade secrets. [..] Trade Secrets Trade secret law is designed to prevent the unauthorized use and disclosure of confidential information and to provide owners with a means to seek damages and injunctions. Both Canada and the U.S. have high standards for the protection of trade secrets. One problem for high-tech companies and other industries in trying to conduct international business, however, has been the lack of protection for confidential information in many foreign countries, including Mexico. In addition, various countries place limitations on how long proprietary information can remain confidential. This lack of protection can frustrate development projects and wreck strategic alliances when the disclosure of confidential information is critical to the transaction. NAFTA is the first international agreement to afford protection for trade secrets. Due to NAFTA, Mexico has comprehensive national provisions for the protection of trade secrets. NAFTA requires each member country to provide legal means to prevent unauthorized disclosure of trade secrets that are in a tangible form. Under NAFTA, countries may not limit the duration of protection of trade secrets or discourage or impede the voluntary licensing of trade secrets. This feature, which is a first for any international agreement, should alleviate some of the reluctance to do business because of the lack of trade secrets protection. |

Works both ways. When I saw the OP here, I backed far away from it. I was "afraid" to post....is that fear real? Who knows. I am thinking some of the others "side's" fears may be real...some not so much. Just my two cents. |

Experimental designs and brain mapping approaches for studying the placebo analgesic effect I hope this is of interest to you and relevant to your query? It's specific to analgesics but there are so many avenues you could go down re: placebo effect that I had to pick one from many.... If you want more or something else, let me know x |

Thanks Phil - I had already looked at NAFTA - surely research results should not qualify as IP - Intellectual Property? I also looked at NRC and saw the same language being used. And this does not to speak specifically to scientific research studies. Sighhh. |
Quote:
What I like about the abstract is this part: The understanding of placebo mechanisms is fundamental and necessary to identify ways of accessing and harnessing these mechanisms in clinical practice to the patients benefit. In other words, with a better understanding of the placebo effect, doctors might be able to use the placebo effect to provide additional relief to the patient above and beyond the effects of the medicine. |

I can definitely understand why this member asked me to post this article, rather than post it herself - and I totally respect and support her decision. I would do the same for any member - on any side of things too. If someone wanted to post an anti-natural-medicine article but didn't want to be the "OP" of it - I'd post it for them in a heartbeat. I personally have seen people disparaged here for what they've posted, and I've definitely seen sources ridiculed, and people ridiculed to a certain extent too - and that's just super unfortunate and unacceptable. Not ONE of us should stand by and ever, ever accept that kind of targeting or those kinds of comments, seriously. At the end of the day, if we're posting and we're feeling this desire to ridicule something or denigrate something - we truly should *not* be posting until we resolve those feelings and can post without those factors present. "I disagree and here's why" is far, far different than "what you've posted is ridiculous!" or "what you've posted is utter nonsense!" (yes, both of which have actually been said here!). Be respectful, be decent, be supportive of the person whether or not you support the information or what they post or their opinion. |
