Abstract: Continuous renal replacement therapy is an important life support technique for critically ill patients,but the premature failure of its circuit significantly reduces the adequacy of patient treatment. This paper reviews the applicable population,predictive factors,outcome measures,prediction performance,and clinical implications of the risk prediction models for the circuit lifespan of continuous renal replacement therapy. The models have different focuses,and their generalizability needs to be validated,so healthcare professionals need to screen the applicability and prediction performance when applying them.
