DSS score

Authors/Creators

Description

The DSS score predicts risk of dengue shock syndrome in adults, based on the percentage increase in hematocrit (HIR), the percentage decrease in platelet count (PDR) between two consecutive days, and WHO 2009 warning signs. It enables triage into low-, intermediate-, and high-risk groups for monitoring and management.
