Terminology and classification of blood purification in critical care in Japan

Abstract

Blood purification in critical care (BPCC) has many indications. Acute kidney injury is a major indication, but there are also non-renal indications that are frequently complicated by kidney injuries. BPCC is performed not only by hemodialysis or hemofiltration using hemofilters, but also various other methods such as apheresis and adsorption. Indications for such a wide range of therapeutic options must be evaluated. Recently, the standardization of terminology and definitions has been attempted (primarily by American and European nephrologists and intensive care physicians) and a standardization committee was organized. The results of this evaluation were made public by the Acute Dialysis Quality Initiative. The Japan Society for Blood Purification in Critical Care has also proposed a standardization of the terminology. Such terminology and definitions should be utilized when making presentations or publishing papers.
