Evaluation of WHO criteria to determine degree of dehydration in children with acute diarrhea
ABSTRACT: To evaluate the
diagnostic accuracy and agreement between the 1980 and 1990 WHO criteria for
determining the de-gree of dehydration in children with acute diarrhea.
Methods This prospective study was conducted in two hospitals from
October 2002 to February 2003. Clinical signs of dehydration all patients were
recorded. The degree of dehydration based on the 1980 and 1990 WHO criteria was
determined and compared with fluid deficit measured by the difference of body
weight on ad-mission and on discharge. Chi-square test and kappa value
analy-ses were performed. Sensitivity, specificity, predictive values, and accuracy
of each WHO criteria were assessed. The prevalence of dehydration was also
determined.
Results Sixty-five patients, comprising 40 boys and 25 girls, were studied.
There was a significant difference between the two WHO criteria in
differentiating between dehydration and non-dehydra-tion (P<0.05). Based on
the 1980 WHO criteria the prevalence of dehydration was 62.2%. Its sensitivity,
specificity, and accuracy in diagnosing dehydration were 100.0%, 55.5%, and 86.2%, respec-tively. Based on the 1990
WHO criteria, the prevalence of dehy-dration was 60.0%. Its sensitivity,
specificity, and accuracy in diag-nosing dehydration were 94.9%, 46.1%, and
75.4%, respectively.
There was also a significant difference between both criteria in determining
severe dehydration (P<0.05). Based on the 1980 cri-teria, the prevalence of severe
dehydration was 15.4%. Its sensi-tivity,
specificity, and accuracy in diagnosing severe dehydration were 30.0%, 94.5%,
and 84.6%, respectively. Based on the 1990 criteria, these results were 40.0%,
94.5%, and 86.2%, respectively. The prevalence was 15.4%. Kappa value comparing
the two WHO criteria was 0.852 in diagnosing dehydration and 0.915 in
diag-nosing severe dehydration. There was no significant difference between the
two criteria in their sensitivity and specificity (P>0.05).
Conclusion Both WHO criteria can be applied to determine de-hydration in
patients with acute diarrhea, although we feel that the 1990 criteria is simpler
