Strep throat pediatric emergencies: impact and performance of a rapid diagnostic test


Summary

Afssaps recommends the systematic use of rapid diagnostic test for streptococcus A in order to better target antibiotic prescribing.
Objective

We evaluated this test in a pediatric emergency department versatile.
Methods

We compared, for each diagnosed angina, the test result to that of culture and have included 216 patients (mean age: 4.8 ± 3.6 years) from January to December 2004.

Results

We identified 57 bacterial tonsillitis (26%). Children with bacterial angina were aged 7 ± 3 years vs 4 ± 3 years for children whose culture was negative (p> 0.05). Test sensitivity was 77% (95% CI: 65-86) and a specificity of 82% (95% CI: 75-87). The PPV was 60% (95% CI: 49-71) and NPV of 91% (95% CI: 85-95). Predictive values of the test were influenced by the age of the child. Read the rest of this entry »
