Abstract
BACKGROUND

There have been different reports on mortality of sepsis; however, few focus on the prognosis of patients with sepsis after surgery.

AIM

To study the clinical features and prognostic predictors in patients with sepsis after gastrointestinal tumor surgery in intensive care unit (ICU).

METHODS

We retrospectively screened patients who underwent gastrointestinal tumor surgery at Peking University Cancer Hospital from January 2015 to December 2019. Among them, 181 patients who were diagnosed with sepsis in ICU were included in our study. Survival was analysed by the Kaplan-Meier method. Univariate and multivariate adjusted analyses were performed to identify predictors of prognosis.

RESULTS

The 90-d all-cause mortality rate was 11.1% in our study. Univariate analysis showed that body mass index (BMI), shock within 48 h after ICU admission, leukocyte count, lymphocyte to neutrophil ratio, international normalized ratio, creatinine, procalcitonin, lactic acid, oxygenation index, and sequential organ failure assessment (SOFA) score within 24 h after ICU admission might be all significantly associated with the prognosis of sepsis after gastrointestinal tumor surgery. In multiple analysis, we found that BMI ≤ 20 kg/m2, lactic acid after ICU admission, and SOFA score within 24 h after ICU admission might be independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery. Compared with SOFA score, SOFA score combined with BMI and lactic acid might have higher predictive ability (area under the receiver operating characteristic curve, 0.859; 95% confidence interval, 0.789-0.929).

CONCLUSION

Lactic acid and SOFA score within 24 h after ICU admission are independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery. SOFA score combined with BMI and lactic acid might have good predictive value.

Core Tip: There have been different reports on mortality of sepsis, but few focus on the prognosis of patients with sepsis after surgery. The purpose of this study was to investigate the prognostic factors of patients with sepsis who were admitted to intensive care unit (ICU) after gastrointestinal surgery. This study retrospectively screened patients who underwent the gastrointestinal tumor surgery at the Peking University Cancer Hospital from January 2015 to December 2019. Among them, 181 patients who were diagnosed with sepsis in ICU were enrolled in our study. In multiple analysis, we found that body mass index ≤ 20 kg/m2, lactic acid after ICU admission, and sequential organ failure assessment (SOFA) score within 24 h after ICU admission might be independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery in ICU. Compared with SOFA score, SOFA score combined with body mass index and lactic acid might have higher predictive ability (area under the receiver operating characteristic curve, 0.859; 95% confidence interval, 0.789-0.929).
