title: Risk factors for healthcare-associated, laboratory-confirmed influenza in hospitalized pediatric patients: a case-control study.
abstract: We conducted a case-control study of 46 hospitalized pediatric patients with healthcare-associated laboratory-confirmed influenza (HA-LCI). We sought to determine the characteristics and outcomes of children with HA-LCI and to identify risk factors for HA-LCI. Although we failed to identify any differences in clinical exposures during the 3 days prior to onset of HA-LCI, multivariate analysis showed that asthma was an independent risk factor for HA-LCI (odds ratio, 3.49 [95% confidence interval, 1.25-9.75]).
