Abstract

We used Pediatric Health Information System data and laboratory records from 3 children's hospitals to determine whether administrative data accurately identify children with laboratory-confirmed influenza. Among 23 282 inpatients, diagnosis codes for influenza detected 73% of laboratoryconfirmed influenza cases, whereas <1% of patients without a diagnosis code had laboratory-confirmed influenza.
