"The leadership of NOF and ISCD has decided after long and careful consideration that a FRAX~R filter should be available, and this will happen in the USA." So speak the proponents of the US FRAX~r filter. Unfortunately, the careful consideration appears to have been driven more by threat than opportunity. In the absence of publication of the in-depth reasons, the only argument, regrettably, appears to be that of maintaining the status quo, justified under the flag of minimising confusion. The question remains as to who is confused? The concept of combining risk factors to provide an estimate of risk that can then drive intervention is well established in many disease areas, particularly in cardiovascular disease. Most clinicians, even "non-expert" ones, understand this and it has made a dramatic impact on health outcomes.
