Is it really true that most clinical decisions have no scientific basis?
Can you give some concrete examples? I was perplexed when I read this in this part (teach medical students to realize the good doctors) from this site: http://www.bmj.com/cgi/content/full/325/7366/711 # Resp1 am an RN and in nursing school is taught to every single speech grounds!
No, but the evidence is limited in many areas, and even when it seems fairly robust, new evidence is often contradictory. When I was in training, corneal abrasions were routinely treated with a patch in the eye. There was a solid reason behind it. Unfortunately, comparison studies were few, small, not well known, and it turned out that the patches generally offers no benefit and in fact is problematic in some cases. new blood pressure drugs are marketed by the blood pressure. But do not worry about lowering blood pressure. What matters is the long-term decline, the cardiovascular risks associated with hypertension. Obviously, I do not stop new drugs effective in phase III clinical trials for fifty years to see how many of the study and control groups of heart disease in its early years later, we assume that there is always a correlation that can not be there. The same applies to new drugs for diabetes. Recently, at least one has been scrutiny, as does a good job of reducing blood sugar, but treaties that have a higher incidence of cardiovascular disease, which is one of the main reasons we are interested in treating type II diabetes, for starters. You will find that its "fundamentals" are a way far from being based Evidence and proof (we hope!) expanded and improved over time. An important part of the scientific method is that not marry the concepts, and we always have be willing to part with the agreements of age when new and better things appear. There is an old medical saying, "Be not the first for which the new treaty, or the latter of which the old is thrown aside. "Unless you're on primary research with a solid study protocol is a good adage.
