I’m Dr. Rafael Fonseca  As an oncologist, I am concerned that there is a fallacy driving the debate about drug prices.  That is the notion that there are many situations where a physician can choose between two medicines that are equivalent, with the only difference between them being their price. This in turn leads to the argument that we need more comparative studies of drugs’ costs versus their effectiveness, so that doctors can make informed choices based on economic considerations. In reality, when multiple treatments exist, there are usually differences between them in either efficacy or safety. A choice based on cost alone will almost always have to sacrifice either efficacy or safety. That’s not a sacrifice patients should be asked to make. Let’s put this fallacy to rest and base medical decisions on medical factors. For more details, go to Facebook/BetterHealthCarePolicy.
