Objectives: To determine whether nurses, using the WHO/UNICEF algorithm for integrated management of childhood illness (IMCI), modified to include dengue infection, satisfactorily classified children in an area endemic for dengue haemorrhagic fever (DHF).
Methods: Nurses assessed and classified, using the modified IMCI algorithm, a systematic sample of 1250 children aged 2 months to 10 years (n = 1250) presenting to a paediatric hospital in Dong Nai Province, Vietnam. Their classification was compared with that of a paediatrician, blind to the result of the nurses' assessment, which could be modified in the light of simple investigations, e.
Classification of dengue using the current World Health Organization (WHO) system is not straightforward. In a large prospective study of pediatric dengue, no clinical or basic laboratory parameters clearly differentiated between children with and without dengue, although petechiae and hepatomegaly were independently associated with the diagnosis. Among the 712 dengue-infected children there was considerable overlap in the major clinical features.

- The study evaluates the effectiveness of the tourniquet test in diagnosing dengue haemorrhagic fever, comparing a standard sphygmomanometer method to a simpler elastic cuff version.
- The standard method showed higher sensitivity and specificity, but both techniques had similar limitations in differentiating between dengue fever and dengue haemorrhagic fever.
- The authors conclude that while the conventional tourniquet test is of limited utility in diagnosing dengue, the elastic version could be beneficial in rural areas, though a negative result does not rule out the infection.
