Additional purpose was to compare the degree of association of APACHE II or III score with mortality in mechanically ventilated critically ill patients. This retrospective study selected patients who had to stay in ICU more than three days. Medical charts were examined for anthropometric and biochemical measurements within the first 72 hours of their admission. The admission scores of APACHE II and III were obtained from the ICU database. Patient’s survival status was also recorded. Student t-test and Mann-Whitney rank sum test were used to compare the demographic and clinical outcomes of survivor and non-survivor groups. Multivariate logistic regression analysis was used to explore odds ratio for patients’ clinical parameters associated with mortality at their admission to the ICU. The study population consisted of one hundred and sixty patients including eighty-three survivors and seventy-seven non-survivors in the ICU. Mean serum albumin level in the non-survivor group was significantly lower than the survivor group. The APACHE II and III scores in the non-survivor group were significantly higher than the survivor group. Univariate analysis showed that APACHE II, III, and albumin significantly associated with the mortality. Albumin still maintained the same degree of association with mortality when adjusting for C-reactive protein in multiple logistic regression analysis, while the association between APACHE II or III and mortality decreased. Our results showed that both APACHE II and III have the similar and significant association with mortality in the ICU. Serum albumin level other than APACHE II and III is an important determinant of morality in the critically ill patients.白蛋白APACHE IIAPACHE III死亡率重症病患albuminmortalitycritically ill patientthesis
