Lit Matters 2: Viral Panels on Kids-- Do we Need Them?

Most children with viral upper respiratory infections improve with supportive care, and broad respiratory viral panels rarely change ED management. In a pediatric emergency department study, comprehensive viral testing increased charges and length of stay without reducing antibiotic use.

Pediatric Viral Panels in the ED

• Common URI baseline: Children can have up to eight upper respiratory infections per year, making viral URI one of the highest-volume pediatric ED complaints and a setting where low-value testing adds up quickly.
• Limited management impact: Comprehensive respiratory viral panel results did not improve clinical outcomes for discharged children, reinforcing that history and physical exam usually answer the key bedside questions.
• Higher patient charges: Respiratory viral panel testing was associated with markedly higher total charges, roughly doubling cost compared with no testing, without a compensating clinical benefit.
• Longer emergency stay: Testing was linked to a longer ED visit, with length of stay stretching from about 2 hours to 4 hours when a panel was sent. We get into the operational implications in the episode.
• Antibiotic decision caution: A positive viral test does not rule out a bacterial infection, and panel use was not associated with a meaningful change in antimicrobial prescribing.
