Currently, doctors recommend one method of Dialysis over the others to treat almost every patient due to treatment mortality rates. However, studies so far have only been observational in nature for their comparison of the treatments available, perhaps creating bias towards one over the other. It may be time to reassess these evaluations and start addressing Dialysis treatments on a more individual basis. Doctor Pietro Ravani asserts that the association between a treatment and mortality rates may relate more to how ill the patients were, rather than the actual treatment itself. Doctors Ravani, Swapnil Hiremath and Mahmoud Malas offer their insight on the matter in an article published by NPR on June 30, 2015. The full article is available via the NPR website.
