Comparison of different scoring systems in prognosis evaluation of acute poisoning / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To compare the predictive value of PSS, APACHEII, SAPSII and SOFA in the prognosis evaluation of acute poisoning.@*Methods@#Clinical data (including PSS score, APACHEII score, SAPSII score and SOFA score, within 24 hours after admission) of 231 acute poisoning patients admitted to the emergency intensive care unit EICU of our hospital from January 2015 to October 2016 was retrospectively analyzed. The patients were divided into the survival group and the dead group according to the 28-day clinical outcomes, comparing the differences of clinical data in each group. To analyze the correlation between PSS score, APACHEII score, SAPSII score and SOFA score in each group, comparing the value and the area under the ROC curve of four scoring systems and evaluate the predictive value of the four scoring systems.@*Results@#Comparing with the survival group and the dead group, PSS score, APACHEII score, SAPSII score and SOFA score were significantly different (P<0.01) . PSS score, APACHEII score, SAPSII score and SOFA score were significantly positive correlation (P<0.01) , the area under the ROC curve (AUC) of the four scoring systems were 0.833, 0.887, 0.843 and 0.843 respectively. The area under the ROC curve (AUC) of APACHEII score was higher than PSS score, SAPSII score and SOFA score, the difference was statistically significant (z=2.351, 2.317, 2.217; P=0.019, 0.021, 0.027) , there was no significant difference in the area (AUC) between the three scoring curves (P>0.05) . The cutoff value (cut-off) , sensitivity, specificity and accuracy rates of PSS score, APACHEII score, SAPSII score and SOFA score were (2.5, 93.1%, 50.9%, 61.5%) , (14.5, 82.8%, 75.7%, 77.48%) , (31.5, 77.6%, 76.90%, 77.08%) , (5.5, 77.60%, 74.60%, 75.35%) .@*Conclusion@#PSS score, APACHEII score, SAPSII score and SOFA score can evaluate the prognosis of patients with acute poisoning, but the APACHEII score is better than the other three scoring systems in evaluating the prognosis for its evaluation ability and accuracy rate.
