  • Investigation of the Function of Modified Shock Index in the Disease Assessment of Emergency Cases

    ObjectiveTo research on the correlation between modified shock index (MSI), traditional vital sign assessment indexes and the proportion of patients entering resuscitation room through emergency triage, and to discuss its significance and advantages for emergency triage. MethodA total of 22 153 emergency patients between January 1 and May 31, 2009 were retrospectively analyzed. We counted the shock index (SI), mean arterial pressure (MAP), MSI, and evaluated the reference range of MSI, based on which, the patients were divided into groups, and the proportion of patients entering resuscitation room in each group was compared. Based on pulse, systolic blood pressure (SBP), SI, MAP and MSI, the patients were again grouped for comparing the proportion of patients entering resuscitation room, and the positive predictive value, negative predictive value, and odds ratio (OR) were also analyzed. ResultsReference value of MSI ranged from 0.34 to 1.70 times/(min·mm Hg) (1 mm Hg=0.133 kPa). Positive predictive values:MSI (16.239%) >MAP (6.115%) >pulse (5.746%) >SBP (5.321%) >SI (3.689%). The negative predictive values were all at high levels and similar with each other. OR:MSI (6.138) >MAP (2.498) >pulse (2.431) >SBP (2.117) >SI (1.361). ConclusionsPulse, SBP, SI, MAP, and MSI are correlated with the proportion of patients entering resuscitation room, and can be regarded as guide for emergency triage, among which MSI may be superior to all other indexes.
