【摘要】Objective To study the value and feasibility of modified early warning score (MEWS) system in assessment of condition and prognosis of patients with acute cerebral infarction in pre-hospital environment. Methods Patients with confirmed diagnosis of acute cerebral infarction in pre-hospital first aid from January to July 2010 served as research object. Relevant on-site data were collected and evaluated using MEWS. The 90th day of admission to hospital was regarded as the observation terminal and the outcomes as the observation indicators. MEWS area under the receiver operator characteristic curve (AUROCC) of patients was calculated , and the relevant prognosis indicators of patients were analyzed. Results The MEWS scores of patients in death group were higher than those in survival group with statistically significant difference(P<0. 05). MEWS AUROCC was 0. 78, indicating greater than or equal to 3 points was the best cut-off point determining the severity degree of patients with acute cerebral infarction in pre-hospital environment. The sensitivity, specificity, accuracy and Youden s index of death prediction of critically ill patients were 45. 45% ,84. 61% ,81. 25%
