Epidemiological analysis of in patients with sepsis in a large tertiary general hospital in Southwest China
Objective To analyze the epidemiological characteristics of hospitalized patients diagnosed with sepsis in a large class Ⅲ general hospital in Southwest China in a period of 2 years,and to explore the risk factors related to death in patients with sepsis.Methods A retrospective study was conducted to select patients with sepsis admitted to Sichuan Provincial People's Hospital from September 1,2021 to August 31,2023,and general characteristics such as gender,age,discharge diagnosis,discharge department,hospitalization cost,length of stay,and prognosis during hospitalization were collected.The baseline of two groups of patients were compared,and the risk factors of in-hospital cause of death in patients with sepsis were analyzed by multivariate Logistic regression.Results A total of 3 568 patients with sepsis were included with median age of 58(35,74)years old.Of all patients,there were 2 147 males(60.17% ).The median length of hospitalization was 13(8,24)days,and the median hospitalization cost was 3.98(1.87,8.83)ten thousand yuan.The departments with more than 100 cases of sepsis in 2 years were central intensive care unit(ICU),pediatrics department,nephrology department,emergency medicine department,emergency intensive care unit(EICU),infectious department,respiratory medicine department,hematology department,neonatal care unit and emergency surgical department.A total of 1 210 patients(33.91% )admitted to ICU(including central ICU and EICU).The hospitalization cost of ICU patients were higher[6.7(3.1,15.5)ten thousand yuan],the hospitalization duration was longer[9(3,17)days],and the mortality was higher[35.29% (427/1 210)].Among 3 568 patients with sepsis,448 died and 3 120 survived during hospitalization.The age,male proportion and hospitalization cost of patients with sepsis in the death group were significantly higher than those in the survival group[age(years old):75(60,86)vs.57(30,71),male proportion:67.86% (304/448)vs.59.07% (1 843/3 120),hospitalization cost(ten thousand yuan):6.7(3.0,16.9)vs.3.7(1.8,8.1)],the ratio of diabetes mellitus was significantly lower than that of survival group[4.91% (22/448)vs.10.45% (326/3 120)],the length of hospitalization was shorter than that of survival group[days:10.0(3.0,19.0)vs.13.0(8.0,24.0)],the differences were statistically significant(all P<0.01).Multivariate Logistic regression analysis showed that male[odds ratio(OR)=0.75,95% confidence interval(95% CI)was 0.59-0.96],elder(OR=1.04,95% CI was 1.03-1.05)and diabetes(OR=0.32,95% CI was 0.19-0.54)were independent risk factors for in-hospital death in patients with sepsis(all P<0.05).Conclusions Sepsis is a heavy burden in Southwest China,especially for ICU,with high mortality,high hospitalization costs,and heavy economic burden on patients and society.Male,elder and diabetes were independent risk factors for in-hospital death of sepsis patients.
