The accuracy of the World Health Organization (WHO) classification system for dengue has been called into question. [75] A study in Indonesian children found that the WHO classification system was in only modest agreement with the intuitive classification by treating physicians, whereas several modified classification systems were in good agreement. [76]

The WHO classification system was found to have a sensitivity of 86% for the detection of dengue shock syndrome. [25] Modified systems that added the above early predictors of compensated shock and considered models using varying combinations of evidence of hemorrhagic tendencies, thrombocytopenia, and hemoconcentration were found to yield higher sensitivities (88-99%).
