PURPOSE: The frequency, extent, time frame, and implications of changes to the @entity3517 ( @entity3517 ) in the 24 hours prior to @entity1167 are not known. Our aim was to determine the prevalence and trends of the @entity3517 prior to in-hospital @entity1167 (IHCA) on a ward, and to evaluate the association between changes in the @entity3517 and in-hospital mortality. METHODS: A total of 501 consecutive adult IHCA @entity1 who were monitored and resuscitated by a medical emergency team on the ward were enrolled in the study between March 2009 and February 2013. The @entity3517 was calculated at 24 hours (MEWS24), 16 hours (MEWS16), and 8 hours (MEWS8) prior to @entity1167 . RESULTS: Out of 380 @entity1 , 268 (70.5%) had a return of spontaneous circulation. The survival rate to hospital discharge was 25.8%. When the @entity3517 was divided into three risk groups (low:  <=2, intermediate: 3-4, high: >= 5), the distribution of the low-risk @entity3517 group decreased at each time point before @entity1167 . However, even 8 hours prior to @entity1167 , 45.3% of @entity1 were still in the low @entity3517 group. The @entity3517 was associated with in-hospital mortality at each time point. However, increasing @entity3517 value from MEWS24 to MEWS8 was not associated with in-hospital mortality [OR 1.24 (0.77-1.97), p = 0.38]. CONCLUSIONS: About half of @entity1 were still in low @entity3517 group 8 hours prior to @entity1167 and an increasing @entity3517 only occurred in 46.8% of @entity1 , suggesting that monitoring the @entity3517 alone is not enough to predict @entity1167 .
