Completed

• Conditions: Bronchiolitis

Brief Summary

Evaluation of Wang's score as a predictor of the duration of oxygen therapy in bronchiolitis

Detailed Description

Bronchiolitis is a viral disease of very variable evolution going from a simple outpatient treatment to the necessity of hospitalization in intensive care.

This epidemic disease is found all year round with a seasonal peak from mid-October to late winter.

The risk factors for progression to severe or prolonged bronchiolitis have been highlighted, but the duration of hospitalization is difficult to predict, which leads to organizational difficulties in the services and additional anxiety for the families.

The management of beds during winter epidemics can be a source of difficulties for hospitalization services, with the need to temporarily increase reception places or transfer children to other hospitals.

Oxygen rescue is the main factor limiting the discharge of the pediatric ward. This criterion seems to us more suitable than the total duration of hospitalization.

Indeed, other factors such as the family environment or food difficulties can delay the child's departure from the service. Their assessment seems to be more subjective, their assessment may vary from one doctor to another.

Better management of beds during winter epidemics could help to avoid changes in service during hospitalization, thus facilitating relationships between caregivers and families.

Primary Outcome Measures

Name	Time	Method
Relationship between the duration of oxygen therapy and Wang's score	through oxygen therapy completion an average of 82 hours	Linear regression, to try to model the duration in hours of oxygen therapy according to Wang's score

Secondary Outcome Measures

Name	Time	Method
use of oxygen therapy	until the end of hospitalization an average of 10 days	Relationship between use of oxygen therapy and Wang's score
length of hospital stay	until the end of hospitalization an average of 10 days	Relationship between length of hospital stay in hours and Wang's score
transfer in intensive care	until the end of hospitalization an average of 10 days	Relationship between secondary transfer in intensive care and Wang's score
