Based on the Chinese Society of ExtraCorporeal Life Support (CSECLS) Registry database, we conducted a retrospective observational study on adult patients supported with ECMO for sepsis (n = 465). On the basis of multivariable logistic regression analyses, four parameters at 24 h post-ECMO initiation (T24) were identified as prognostic factors associated with in-hospital mortality: age, vasoactive inotropic score (VIS), partial pressure of oxygen in arterial blood (PaO2), and lactate clearance. The sepsis-ECMO score was calculated based on these prognostic factors, which were converted into categorical variables. The area under the receiver operating characteristic curve for the sepsis-ECMO score was 0.704 (95% confidence interval [CI]: 0.658-0.751). Four risk classes, namely class Ⅰ (score 0), class Ⅱ (score 5), class Ⅲ (score 6-10), and class Ⅳ (score ≥ 11), were identified according to sepsis-ECMO score quartiles. Patients in the lower sepsis-ECMO score classes had significantly better survival than those in the higher classes (log-rank test, p < 0.001). The sepsis-ECMO score may help in the risk stratification of patients, facilitate the communication of objective prognostic information, and provide a clearer direction for shared decision-making.</p>","PeriodicalId":8844,"journal":{"name":"ASAIO Journal","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This multicenter, retrospective analysis included 83 consecutively enrolled patients undergoing continuous-flow LVAD implantation. Multivariable logistic regression identified independent predictors of early RHF, whereas receiver operating characteristic (ROC) curve analysis assessed predictive value. Among the 83 patients, 21 (25.3%) experienced early RHF. Logistic regression analyses revealed that the direct bilirubin to total bilirubin (DBIL/TBIL) ratio on admission was significantly correlated with early RHF (adjusted odds ratio [OR]: 2.41, 95% confidence interval [CI]: 1.35-4.31, p = 0.003). The DBIL/TBIL ratio on admission exhibited the highest area under the receiver operating characteristic curve (AUC) (0.767, 95% CI: 0.661-0.852). Internal validation using bootstrap techniques resulted in a mean AUC of 0.767 (95% CI: 0.640-0.879), whereas external validation in a cohort of 31 patients demonstrated an AUC of 0.682 (95% CI: 0.491-0.837).
