Investigation on compliance with sepsis bundle and outcomes in patients with septic shock in Changshu area / 中华急诊医学杂志

ABSTRACT

Objective:To investigate the rate of compliance with sepsis Bundle and outcomes in patients with septic shock in intensive care units (ICU) in Changshu area.Methods:A multi-center retrospective study was conducted on patients who were diagnosed as septic shock in ICU of three hospitals in Changshu area from January 2014 to October 2017. Patients who were diagnosed as septic shock meeting the 2016 diagnostic criteria were enrolled. The exclusion criteria were paients younger than 18 years, pregnancy, death within 6 h of admission, halfway abandoned treatment, and those who had entered other studies on septic shock intervention. Clinical characteristics, past history, situation on admission, Bundle completion at 1 h, 3 h and 6 h, and prognosis were recorded. Patients were divided into the survival group and death groups according to whether they survived or not. The differences of completion of Bundle indicators between the two groups were compared. The independent risk factors of prognosis were analyzed by Logistic regression analysis, and the survival curve was plotted by Kaplan-Meier method.Results:Totally 207 patients from 3 hospitals were enrolled in this study. The complition rate of 1 h Bundle was 27.1%, of which the completion rate of serum lactate determination was 81.2%, the completion rate of blood culture before antibiotic administration was 72.5%, the completion rate of broad-spectrum antibiotic administration was 48.4%, the completion rate of fluid resuscitation was 74.4%, and the completion rate of vasopressors to maintain MAP≥65 mmHg was 86.0%; the completion rate of 3 h Bundle was 67.6%, of which the completion rate of serum lactate determination was 97.1%, the completion rate of blood culture before antibiotic administration was 84.5%, the completion rate of broad-spectrum antibiotic administration was 97.1%, and the completion rate of fluid resuscitation was 76.8%; the completion rate of 6 h Bundle was 30.4%, of which the completion rate of vasopressors to maintain MAP≥65 mmHg was 98.1%, the completion rate of reassessed volume stasis (at least two indexes) was 48.3%, the completion rate of central venous pressure (CVP) was 42.5%, the completion rate of ScvO 2 was 10.6%, the completion rate of bedside ultrasound was 48.8%, the completion rate of passive leg raising and rehydration therapy was 42.5%, and the completion rate of re-evaluation of lactate was 55.1%. The total Bundle completion rate at 3 h and 6 h was 27.1%. There was no significant difference in the completion of the three hospitals. The mortality of patients with septic shock was 58.9%, length of stay in the ICU was 10 d (5, 23) d, and length of hospital stay was 14 d (6, 26) d. Univariate analysis showed that antibiotic use time, CVP, bedside ultrasound, passive leg raising and rehydration experiments, re-evaluation after elevated lactate, 6 h Bundle completion, total Bundle completion at 3 and 6 h, and APACHE Ⅱ score were associated with the prognosis (all P<0.01). Logistic regression analysis showed that CVP ( OR=23.236, P=0.001), passive leg raising and rehydration experiments ( OR=0.102, P=0.012), re-evaluation after elevated lactate ( OR=0.197, P=0.001) and APACHEⅡ score ( OR=1.103, P<0.01) were risk factors of the prognosis. Kaplan-Meier analysis showed that the 28 d survival rate was significantly higher if 6 h Bundle was completed (Log Rank χ 2=8.944, P=0.003). Conclusions:The compliance with sepsis Bundle is not high in Changshu area, and the compliance is closely related to the prognosis, so it needs to improve compliance with the guidelines.
