Evaluation of the Prognosis for Elderly Critical Patients in Emergency Department Using MEWS Score and APACHE II Score

Objective To study the assessment value of Modified Early Warning Score(MEWS) and Acute Physiology and Chronic Health Evaluation(APACHE Ⅱ) score for the prognosis of critical elderly patients in emergency department.Methods 158 elderly patients from emergency ICU of Xuanwu Hospital of Capital University of Medical Sciences were collected.MEWS score and APACHE Ⅱ score were calculated for them and the differences were compared between death group and survival group.The difference of the area under receiver operating characteristic curve(AUROCC) were compared between MEWS score and APACHEⅡ score.The death rate were analyzed in the different groups with MEWS score ≤ 3,4-6,7-9,and ≥ 10 respectively.The correlation analysis of MEWS score and APACHE Ⅱscore was done.Results MEWS score and APACHE Ⅱ score in death group were 8.06±2.71 and 24.60±4.20 respectively,those in survival group were 4.80±2.47 and 19.06±3.93 respectively(P0.01).AUROCC of MEWS score was 0.814,with no significant difference between MEWS score and APACHE Ⅱscore(P0.05).With MEWS increasing,the fatality rose(P0.01).MEWS score and APACHE Ⅱ score were correlated(r=0.647,P=0.001).Conclusion MEWS score,as well as APACHE Ⅱ score,is a convenient and fast scoring system,with which the disease condition and prognosis of critical elderly patients can be assessed.
