The severity of IE was determined by a systemic inflammatory response syndrome (SIRS) score [9 (link)], quick SOFA (qSOFA), and SOFA scores [10 (link)]. The Charlson comorbidity index (CCI) evaluated patents’ comorbidity [11 (link)]. We previously reported that SOFA score was a good predictive marker among IE patients for in-hospital death [7 (link)]. Thus, we evaluated severity of IE by SOFA score.
The patients were divided into two groups: patients who were eligible for clinical trials (RCT appropriate group), and those who were not (RCT inappropriate group). Then, patients’ characteristics (age and sex); pathogens isolated; clinical outcomes such as the treatments and/or results; 30-day or in-hospital mortality; and the reasons of exclusion from the clinical trial were evaluated.
