External validation of the Michigan PICC catheter–associated bloodstream infections score (MPC score) for predicting the risk of peripherally inserted central catheter–associated bloodstream infections: A single-center study in Japan

Abstract The Michigan peripherally inserted central catheter–associated bloodstream infection score (MPC score) had been developed for hospitalized medical patients but had not been externally validated. A retrospective analysis of a clinically heterogeneous case-mix in a university hospital cohort in Japan failed to validate its originally reported good performance.
