Sensitivity of lung ultrasound in Ugandan children with radiographic pneumonia

Nathaniel Meuser-Herr, MD

Summary

BACKGROUND: Prompt recognition and treatment of pneumonia is crucial, as the case-fatality rate in untreated children is high, often exceeding 20%.  However, the complications of integrated management of pneumonia with often co-existing malaria, malnutrition and diarrheal illnesses impact the sensitivity of the diagnostic criteria.  Lung ultrasound (L-US) has been shown to be comparable or even more sensitive than CXR in the diagnosis of pediatric pneumonia in multiple studies completed in developed countries.

GAP: No studies of L-US in pediatric pneumonia have been conducted in low-middle income countries where children have risk factors for more severe disease.

HYPOTHESIS: We hypothesize that L-US will perform with at least 80% sensitivity and that with a standardized ultrasound education course and technique, L-US operators will demonstrate almost perfect agreement.

METHODS: A L-US and CXR performed on all children, between the ages of 2-months and 5-years, presenting with a diagnosis of pneumonia by WHO criteria.  Operators and radiologists will be blinded to the alternate imaging findings. Interobserver agreement will be tested in comparison of L-US findings between operators who will have received a standardized course in L-US technique and interpretation.

RESULTS: Pending.

IMPACT: Lung ultrasound has the potential to be come a validated diagnostic study in pediatric pneumonia in the setting of low-middle income countries.  It can be taught and implemented in rural areas where CXR is not available. This would build capacity in the diagnosis, referral, and management of severe pneumonia.
