The QCC campaign at the emergency center was themed as minimizing incidence of risky transport of critically ill patients,which aimed at continued quality improvement by means of conditions review,problem analysis,measures making,and procedure improvement.The incidence of risky transports dropped from 26％ to 0.9％ in six months.Another promising outcome was a sharp betterment of clinical nurse management. It has proved that QCC can effectively downsize risky transports of critically ill patients,making it a functional means to improve nursing quality.

Objective To estimate the value of T cell subset monitoring on early diagnosis and prognosis in traumatic sepsis patients defined by sepsis-3.Methods A total of 102 severe trauma patients were prospectively collected in an Emergency Intensive Care Unit (EICU) of a tertiary hospital from 1st July 2017 to 30th September 2017.Finally 28 patients were confirmed as sepsis according to the sepsis-3 guideline.The levels of blood T cell subsets (CD3,CD4,and CD8) were measured at day 1,3 and 7 after ICU admission and after diagnosis.Receiver operating characteristic curve and multivariate regression analysis were used.Results The levels of CD3 and CD4,and CD4/CD8 ratio in severe trauma patients first decreased and then increased within one week after admission,while CD8 level first increased and then decreased.The levels of CD3 and CD4 and CD4/CD8 ratio showed a decreased tendency and CD8 level showed an increased tendency in the death and traumatic sepsis groups.The CD4/CD8 ratio at day 1 after admission was relatively effective in diagnosing traumatic sepsis.The area under the ROC curve was 0.901 with a sensitivity and specificity of 88.89％ and 83.33％,respectively.The CD4/CD8 ratio at day 1 after diagnosis of traumatic sepsis was a risk factor for predicting patient mortality (OR=1.43;95％CI:1.27-1.89).Conclusions Cellular immunity in severe trauma patients presents a process of inhibition before recovery.The CD4/CD8 ratio can better diagnose traumatic sepsis and evaluate the prognosis..
