Question: What are the clinical phenotypes and pathogen associations of pediatric and adult Emergency Department visits for abnormal liver function tests?
Finding: Pediatric visits showed fever-predominant profiles with temporal correlations with respiratory viruses, whereas adult visits revealed population-level temporal associations between enteric pathogens and infectious gastroenteritis, upper gastrointestinal disorders, and metabolic comorbidity clustering.
Meaning: These findings provide novel population-level evidence of age-specific pathogen associations and support distinct age-stratified clinical diagnostics.

In order to care for an ill or injured child, it is crucial that every emergency department (ED) has a minimum set of personnel and resources because the majority of children are brought to the geographically nearest ED. In addition to adequate preparation for basic pediatric emergency care, a comprehensive, specialized healthcare system should be in place for a critically-ill...
