Abstract:
Objective To investigate the power of the simplified acute physiology score Ⅲ ( SAPSⅢ) for prediction of outcome for patients with severe sepsis admitted to the intensive care unit ( ICU ). Methods A retrospective study was conducted. 677 severe sepsis patients with age ≥ 18 years old and the survival time in emergency ICU≥24 hours admitted to the emergency ICU of Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2008 to December 2011 were enrolled. The acute physiology and chronic health evaluationⅡ ( APACHEⅡ), sequential organ failure assessment ( SOFA ), SAPSⅡ, SAPSⅢ, and mortality in emergency department sepsis ( MEDS ) scores were recorded based on the poorest value within 24 hours of ICU admission. The 28-day result as denoted as survival or death was considered as the end point of the study. The ability to predict mortality by the score systems was assessed by using receiver operating characteristic ( ROC ) curve analysis and binary logistic regression models. Results Among the 677 patients with severe sepsis, 284 cases died within 28 days after admission, and the mortality rate was 41.9%. Compared with survivors, the patients in non-survival group was older with higher APACHEⅡ, SOFA, SAPSⅡ, SAPSⅢ, and MEDS scores and higher ratio of underlying diseases, such as primary hypertension and renal dysfunction, and they had more organ injury, higher ratio of lung infection and bacterial infection ( P < 0.05 or P < 0.01 ). It was identified by logistic regression that the APACHEⅡ, SOFA, SAPSⅡ, SAPSⅢand MEDS scores were significantly independent factors in 28-day death prediction in patients with severe sepsis ( all P=0.000 ). The rank of areas under the ROC curve ( AUC ) from high to low were MEDS ( 0.970 ), APACHEⅡ( 0.893 ), SAPSⅢ ( 0.875 ), SOFA ( 0.871 ), and SAPSⅡ ( 0.860 ), respectively. SAPSⅢ score and APACHEⅡ, SOFA, SAPSⅡscores were found to have an equivalent capacity in predicting the prognosis ( all P>0.05 ). The MEDS score in predicting the prognosis was obviously better than that of APACHEⅡ, SOFA, SAPSⅡ, and SAPSⅢscores ( all P<0.05 ). The MEDS score showed the best sensitivity ( 91.5%), and specificity ( 89.1%). The 28-day mortality in cases of MEDS≥11 was 85.8%. Conclusions ①For patients with severe sepsis who were admitted to ICU, MEDS was superior to APACHEⅡ, SOFA, SAPSⅡ, and SAPSⅢscores in predicting prognosis. MEDS≥11 may indicate a higher mortality rate.②SAPSⅢscore has comparable predictive capability with APACHEⅡ, SOFA and SAPSⅡscores may be recommended for prediction of the prognosis of patients with severe sepsis in ICU. But the SAPSⅢscore is unsuitable for predicting the prognosis of patients with acute sepsis in ICU options, and it is not superior to that of SAPSⅢscore in predicting prognosis of patients with sepsis in the emergency ICU than other score systems.
