Table 3 Proportion of severe vs non-severe dengue cases admitted from ambulatory care using either current admission practice or using warning signs as admission criteria (percentage of cases (95% confidence interval))

From: Utility of warning signs in guiding admission and predicting severe disease in adult dengue

  DHF I-IV P-value Non-DHF I-IV P-value
Admission criteria + clinical judgment 59% (46%, 70%) 0.02 12% (8%, 16%) <0.01
WS 79% (67%, 87%)   48% (43%, 54%)  
  DHF II-IV P-value Non-DHF II-IV P-value
Admission criteria + clinical judgment 56% (4%, 71%) <0.01 16% (12%, 20%) <0.01
WS 100.0% (88%, 100%)   48% (43%, 54%)  
  SD P-value Non-SD P-value
Admission criteria + clinical judgment 69% (39%, 91%) 0.13 19% (15%, 23%) <0.01
WS 100.0% (66%, 100%)   52% (47%, 58%)  
  1. WS Warning signs, DHF dengue hemorrhagic fever, SD severe dengue.
  2. P-values indicate the significance of the difference in proportion between current admission practice and using warning signs as admission criteria.
