Objectives: To investigate the relationship between sepsis prevalence and disease types
in intensive care units (ICUs), as well as the effect of knowledge of the health care
workers about the sepsis guidelines on sepsis morbidity and mortality.
Methods: A one-day cross-sectional survey was conducted in five ICUs in the cities of
Chongqing and Guizhou, China. The included patients were divided into three groups:
the internal medicine group (Group A), surgery group (Group B), and trauma group
(Group C). Sepsis was diagnosed by the 2012 Sepsis Guidelines, and the prevalence and
28-day mortality were statistically analyzed. The relationship between the knowledge of
health care workers about sepsis and morbidity and mortality was analyzed.
Results: Among the enrolled 71 patients, the sepsis prevalence rate was 81.5%, 66.7%,
and 87.0% in Groups A, B, and C, respectively. In total, the 28-day mortality rate was
36.4%, 42.9% and 20.0% in Groups A, B, and C, respectively, indicating no significant
difference. The sepsis prevalence was 66.7%, 90.0%, 90.9%, 100.0% and 76.9% in the
five ICUs. The average cognitive score of each hospital was 68.5 ± 15.4, 65.7 ± 16.7,
69.0 ± 23.3, 25.0 ± 8.4, and 61.4 ± 19.9 points in the five ICUs. Cognitive scores were
not associated with prevalence of sepsis, but they were negatively related with sepsis
Conclusions: Sepsis prevalence and mortality are not associated with diseases types
within ICUs, but the knowledge of sepsis of health care workers is associated with the
prognosis of sepsis patients.
