Erratum: Potential Survival Benefit of Polymyxin B Hemoperfusion in Septic Shock Patients on Continuous Renal Replacement Therapy: A Propensity-Matched Analysis

<b><i>Background/Aims:</i></b> We assessed the survival benefit of polymyxin B hemoperfusion (PMX) in septic shock patients starting continuous renal replacement therapy (CRRT), who are known to have an increased rate of mortality. <b><i>Methods:</i></b> Adult patients in the Japanese diagnosis procedure combination database satisfying the following criteria were enrolled: hospitalized in 2007-2012; diagnosed as having sepsis; required noradrenaline and/or dopamine; and started CRRT in intensive care unit. Propensity scores for receiving PMX were created from patient and hospital characteristics. <b><i>Results:</i></b> Of 3,759 eligible patients, 1,068 received PMX. Propensity-score matching produced a matched cohort of 978 pairs. The 28-day mortality was 40.2% (393/978) in the PMX group and 46.8% (458/978) in the control group (p = 0.003). Logistic regression analysis revealed a significant association between the use of PMX and decreased 28-day mortality (adjusted OR 0.75; 95% CI 0.62-0.91). <b><i>Conclusion:</i></b> This large retrospective study suggests that septic shock patients starting CRRT may benefit from PMX.
