Abstract
BACKGROUND The Sequential Organ Failure Assessment (SOFA) score is an important tool in diagnosing sepsis and quantifying organ dysfunction. However, despite emerging evidence of differences in sepsis pathophysiology between women and men, sex is currently not being considered in the SOFA score. We aimed to investigate potential sex-specific differences in organ dysfunction, as measured by the SOFA score, in patients with sepsis or septic shock and explore outcome associations. METHODS Retrospective analysis of sex-specific differences in the SOFA score of prospectively enrolled ICU patients with sepsis or septic shock admitted to one of 85 certified Swiss ICUs between 01/2021 and 12/2022. RESULTS Of 125,782 patients, 5947 (5%) were admitted with a clinical diagnosis of sepsis (2244, 38%) or septic shock (3703, 62%). Of these, 5078 (37% women) were eligible for analysis. A statistically significant difference of the total SOFA score on admission was found between women (mean 7.5 ± SD 3.6 points) and men (7.8 ± 3.6 points, Wilcoxon rank-sum p < 0.001). This was driven by differences in the coagulation (p = 0.008), liver (p < 0.001) and renal (p < 0.001) SOFA components. Differences between sexes were more prominent in younger patients < 52 years of age (women 7.1 ± 4.0 points vs men 8.1 ± 4.2 points, p = 0.004). No sex-specific differences were found in ICU length of stay (women median 2.6 days (IQR 1.3-5.3) vs men 2.7 days (IQR 1.2-6.0), p = 0.13) and ICU mortality (women 14% vs men 15%, p = 0.17). CONCLUSION Sex-specific differences exist in the SOFA score of patients admitted to a Swiss ICU with sepsis or septic shock, particularly in laboratory-based components. Although the clinical meaningfulness of these differences is unclear, a reevaluation of sex-specific thresholds for SOFA score components is warranted in an attempt to make more accurate and individualised classifications.

Predictive values of the SOFA score and procalcitonin for septic shock after percutaneous nephrolithotomy. Urolithiasis 2022; 50:729-735. [PMID: 36214882 PMCID: PMC9584975 DOI: 10.1007/s00240-022-01366-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 10/04/2022] [Indexed: 11/04/2022]
Abstract
To investigate the value of combination of the Sequential Organ Failure Assessment (SOFA) score and procalcitonin (PCT) for prediction of septic shock after percutaneous nephrolithotomy (PCNL). A total of 1328 patients receiving PCNL for renal calculi were allocated into control group (without septic shock) and septic shock group, and related data were retrospectively collected. Univariate analysis was firstly performed, and the variables with two sided P < 0.10 were then included in logistic regression analysis to determine independent risk factors. Receiver operating characteristic (ROC) curve was utilized to evaluate the predictive values. Area under curve (AUC) was compared using Z test. Postoperative septic shock was developed in 61 patients (4.6%) and not developed in 1267 patients (95.3%). Multivariate analysis demonstrated that SOFA score (OR: 1.316, 95% CI 1.125–1.922), PCT (OR: 1.205, 95% CI 1.071–1.696) and operative time (OR: 1.108, 95% CI 1.032–1.441) were independent risk factors for septic shock with adjustment for sex, history of urolithiasis surgery, positive history of urine culture and history of PCNL. The ROC curves demonstrated that the AUCs of SOFA score and PCT for predicting septic shock after PCNL were 0.896 (95% CI 0.866–0.927) and 0.792 (95% CI 0.744–0.839), respectively. The AUC of their combination was 0.971 (95% CI 0.949–0.990), which was higher than those of individual predictions (vs 0.896, Z = 4.086, P < 0.001; vs 0.792, Z = 6.983, P < 0.001). Both the SOFA score and PCT could be applied in predicting septic shock after PCNL, and their combination could further elevate the diagnostic ability.

Gao M, Zhu Z, Liu M, Chen J, Chen H. Predictive accuracy of the modified SOFA score, SIRS criteria, and qSOFA score for uroseptic shock after mini-percutaneous nephrolithotomy. Urolithiasis 2022; 50:455-464. [PMID: 35201365 DOI: 10.1007/s00240-022-01318-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 02/11/2022] [Indexed: 11/30/2022]
Abstract
The purpose of this study was to determine the plausibility and utility of utilizing a modified SOFA (mSOFA) score for predicting uroseptic shock after mini-percutaneous nephrolithotomy. A cohort of 707 patients who received mini-PCNL from August 2019 to December 2020 was retrospectively evaluated. The area under receiver operating characteristic curve (AUROC) was used to compare the predictive value of septic shock between mSOFA, systemic inflammatory response syndrome (SIRS) and qSOFA. Among 707 patients, 24 patients experienced uroseptic shock after mini-PCNL. Compared with the no uroseptic shock group, the proportion of females and rates of preoperative urine culture, renal pelvis urine culture and stone culture positivity were higher in the uroseptic shock group, with high levels of preoperative C-reactive protein (CRP) and postoperative procalcitonin (PCT). In the uroseptic shock group, the mSOFA score increased by two or more points in 83.3%; 79.2% had at least two SIRS criteria, and 100% had a qSOFA score of at least one point. mSOFA score (AUROC = 0.866, 95% CI: 0.779-0.954) exhibited greater discrimination for uroseptic shock after PCNL than SIRS (AUROC = 0.838, 95% CI: 0.742-0.943) and qSOFA (AUROC = 0.851, 95% CI: 0.811-0.892). In conclusion, the predictive value of the modified SOFA score for uroseptic shock after mini-PCNL was greater than that of the qSOFA score or SIRS.
