Could quick SOFA and SOFA score be a predictive tool for 30-day and in-hospital mortality in acute empyema?

While acute empyema is a critical infectious disease showing a high mortality rate, there are no prognostic tools to evaluate the disease severity and prognosis for patients. We conducted a retrospective cohort to determine whether quick Sequential Organ Failure Assessment (qSOFA) and SOFA score can predict the disease severity and prognosis of acute empyema. A total of 53 patients were enrolled in the study. The mean age was 69 years and 41 patients (77%) were male. Twenty-two patients (42%) had multiple underlying diseases with the Charlson comorbidity index ≥3. The-30 days, and in-hospital deaths were 7 (13%) and 10 (19%), respectively. The area under the ROC curve of SOFA score and CCI for 30-day and in-hospital deaths were 0.814 (p = 0.073) and 0.752 (p = 0.082), 0.848 (p = 0.07) and 0.762 (p = 0.011), respectively. Univariate analysis showed that qSOFA ≥2 and SOFA score ≥2, isolation of potentially drug-resistant (PDR) pathogen, high CCI (≥3), performance status of 2-4, surgical intervention, and anaerobic bacteria involvement were prognostic factors. Of these, multivariate logistic regression analysis showed that qSOFA ≥2 and SOFA score ≥2 (p = 0.011), isolation of PDR pathogen (p = 0.005), and high CCI (≥3) (p = 0.015) were independently poor prognostic factors. We concluded that qSOFA and SOFA scores could predict the disease severity and prognosis in acute empyema. Additionally, isolation of PDR pathogens and high CCI could be poor prognostic factors for patients.
