The diagnostic accuracy of Clinical Dehydration Scale in identifying dehydration in children with acute...

Area of Science:

• Pediatrics
• Emergency Medicine
• Diagnostic Accuracy Studies

Background:

• Dehydration is a common complication of acute gastroenteritis in children.
• Accurate clinical assessment tools are crucial for timely management.
• The Clinical Dehydration Scale (CDS) is used to evaluate dehydration severity.

Purpose of the Study:

• To systematically update the diagnostic accuracy of the CDS for recognizing dehydration in children.
• To evaluate the CDS's performance in different income settings.

Main Methods:

• A systematic literature search was conducted across six databases.
• Included studies focused on children aged 1-36 months with acute gastroenteritis.
• The CDS was the index test, and post-illness weight gain was the reference standard.

Main Results:

• Three studies with 360 children were analyzed.
• In high-income countries, the CDS showed strong accuracy for ruling in moderate/severe dehydration (LR+ 5.2-6.6).
• The CDS had limited value for ruling out dehydration or assessing mild dehydration (<6%) in any setting.

Conclusions:

• The CDS is a useful tool for assessing moderate to severe dehydration in high-income settings.
• Evidence suggests limited utility in low-income countries.
• Further research is needed due to limited data, and findings should be interpreted cautiously.
