Effect of rapid influenza testing on the clinical management of paediatric influenza

摘要

>Background  Rapid tests are now widely available to assist the diagnosis of influenza; implementation may optimise the use of antiviral and antibiotic agents in the clinical management of influenza. >Objective  To explore the clinical management of children with influenza‐like illness (ILI) when rapid influenza tests were and were not performed. >Methods  Between 15 January 2007 and 30 April 2007, a standardised questionnaire was used to record the clinical features of children aged 1–12 years who presented to office‐based paediatricians in Germany with febrile ILI during periods of local influenza activity. For each paediatric contact, a clinical diagnosis of either ‘influenza positive’, ‘influenza negative’ or ‘suspected ILI’ was made. Where performed, the outcome of a Clearview Exact Influenza A + B rapid test was recorded. Prescriptions for antiviral agents and antibiotic medications were also recorded. >Results  A total of 16 907 questionnaires were evaluated. After fever (an entry criteria for all children), cough (84·6%), fatigue/decreased activity (83·0%), rhinorrhoea (73·7%) and headache (67·1%) were the most common symptoms. Influenza was clinically diagnosed in 56·8% (9596/16 907) of cases. The antiviral oseltamivir was prescribed for 24·6% (178/725) of children who were influenza positive by symptom assessment alone and 60·1% (4618/7685) of children who were influenza positive by rapid test. Antibiotics were less commonly prescribed for children who were influenza positive by rapid test [3·5% (271/7685) versus 17·2% (125/725) for symptom assessment alone]. >Conclusions  In children with ILI, a positive rapid test result for influenza promotes the rational use of antiviral agents and reduces the inappropriate use of antibiotic medications.
