RSV Burden in Outpatient Settings

Recruiting

• Conditions: Outpatient; RSV Infection; Otitis Media; Children, Only; Bronchiolitis; Pneumonia

• Registration Number: NCT04743609
• Lead Sponsor: Association Clinique Thérapeutique Infantile du val de Marne

Brief Summary

Strengthening outpatient low respiratory tract infection surveillance to document the burden of Respiratory Syncytial Virus (RSV)

Detailed Description

The study protocol is designed with three key components: 1. Build on existing PARI outpatient syndromic surveillance by adding laboratory multiplex testing of LRTI samples (RSV, Influenza, SARS-COV-2) 2. Follow all bronchiolitis through the PARI RWE database and document "patient journey" for 5 years after first medical visit 3. Review the electronic PARI data of three previous seasons in order to document the impact of LRTI attributable to RSV in children \< 2 years in France prior to enhanced surveillance

Primary Outcome Measures

Name	Time	Method
RSV proven	day of enrrollement	Percentage of children with proven RSV disease (bronchiolitis, AOM or pneumonia)

Secondary Outcome Measures

Name	Time	Method
Proportion of AOM by RSV status	day of enrrollement	Percentage of children with AOM by RSV status
Proportion of pneumonia by RSV status	day of enrrollement	Percentage of children with pneumonia by RSV status
Score of Quality of life	15 days and 6 months	Assessed by the quality of life infant scale (from 0-100, so that higher scores indicate better Health-Related Quality of Life)
Caracteristic of tests	day of enrrollement	Sensitivity, specificity, positive predictive value, negative predictive value positive and negative likelihood ratio of the SARS-Cov2, influenza A/B and RSV rapid antigenic test compared to the reference test by multiplex RT-PCR
Proportion of Respiratory Tract Infections with SARS-CoV-2	day of enrrollement	Percentage of children with Respiratory Tract Infections with SARS-CoV-2
Proportion of Respiratory Tract Infections by RSV Status	day of enrrollement	Percentage of children with Respiratory Tract Infections by RSV Status
Proportion of associated complications by RSV status	day of enrrollement, 15 days and 6 months	Percentage of children with associated complications by RSV status
