Objective:To explore the impact of completion rates of 3-hour and 6-hour sepsis bundle therapy on prognosis of patients with septic shock in Prefecture-level grade A hospitals, and analyze the risk factors for prognosis.Methods:A retrospective analysis was conducted to patients with septic shock in the intensive care unit (ICU) of Liaocheng People's Hospital, Shandong Province from January 1, 2020 to December 31, 2021. The data of gender, age, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), sites of infection, pathogenic microorganisms, completion rates of 3-hour and 6-hour sepsis bundle therapy, 28-day prognosis were collected. Logistic regression analysis was used to identify risk factors for patients' mortality at 28-day.Results:① Among 159 patients with septic shock, 93 survived and 66 died with 28-day. There were no significant differences in gender and age between the survival group and death group. Compared with the survival group, APACHE Ⅱ score and SOFA score were significantly higher in the death group [APACHE Ⅱ score: 26.85±5.04 vs. 20.67±4.29, SOFA score: 12.86±3.02 vs. 9.37±2.51, both P < 0.05]. ② Sites of infection in the 159 patients: 47 cases were abdominal infection (29.6%), 36 case were bloodstream infection (22.6%), 31 cases were pulmonary infection (19.5%), 16 cases were soft tissue infection (10.1%), 13 cases were urinary tract infection (8.2%), 12 cases were biliary tract infection (7.5%), and 4 cases were other sites infection (2.5%). Pathogens were found in 128 cases and the positive rate was 80.5%, including 90 cases of Gram-negative (G -) bacilli (56.6%), 27 cases of Gram-positive (G +) cocci (17.0%) and 11 cases of fungi (6.9%). The top three pathogenic bacteria were Escherichia coli (49 cases, 30.8%), Klebsiella pneumoniae (21 cases, 13.2%) and Staphylococcus aureus (15 cases, 9.4%). The differences were not statistically significant. ③ Among the 159 patients, 101 cases completed 3-hour sepsis bundle therapy (63.5%), including 67 cases (72.0%) in survival group and 34 cases (51.5%) in death group; 106 cases completed 6-hour sepsis bundle therapy (66.7%), including 70 cases (75.3%) in survival group and 36 cases (54.5%) in death group. The differences between the two groups were statistically significant (all P < 0.05). ④ The factors (APACHE Ⅱ score, SOFA score and completion rate of 3-hour and 6-hour sepsis bundle therapy) affecting the prognosis in the univariate analysis were included in the binary Logistic regression analysis, and the results showed that the APACHE Ⅱ score, SOFA score, completion rate of 3-hour sepsis bundle therapy were independent risk factors affecting mortality within 28-day [odds ratio ( OR) was 1.216, 1.303, 0.402, all P < 0.05]. Conclusions:The higher APACHE Ⅱ score and SOFA score in septic shock, the worse the prognosis. Improving the completion rates of 3-hour and 6-hour bundle therapy especially the completion rate of 3-hour bundle therapy can reduce the mortality of patients and improve the prognosis.
