The prognostic value of modified early warning score of ICU elderly patients in emergency

Abstract

Objective To study the prognostic value of modified early warning score (MEWS) and Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) score in emergency ICU elderly patients.Methods 113 elderly patients were collected in emergency ICU,after admission to calculate the MEWS score and APACHE Ⅱ score,the MEWS score and APACHE Ⅱ score difference were compared between death group and survival group.the differences were compared in MEWS score ≤ 3,4 ～6,7 ～ 9,≥ 10 scores groups respectively;analysis of the MEWS score and APACHE Ⅱ the relevance score.the correlation analysis of the MEWS score and APACHE Ⅱ score was given.Results The MEWS(7.91 ± 2.42) point and APACHE Ⅱ (21.9 ± 4.18) point in death group were greater than that in survival group [(4.51 ± 2.14) point,(19.53 ± 4.37) point] (t =7.49,2.70,all P ＜ 0.01).With MEWS score increasing,the fatality rate rose(P ＜0.01).the MEWS score and APACHE Ⅱ score was correlated(r =0.617,P ＜ 0.01).Conclusion The MEWS score was a simple and quick scoring system,as well as APACHE Ⅱ,it can predict the prognosis of elderly patients in emergency department,it has important application value.
