One of the top research priorities in acute kidney injury is related to the timing of renal replacement therapy (RRT) initiation. The purpose was to develop an index that might serve as a standardized concept of timing of initiation of RRT. ⋯ We have developed a simple Score (IRRIV Score) to identify patients at high risk of requiring RRT. This score may serve as a standardized definition of the timing of initiation of RRT.
