High-flow nasal cannula oxygen therapy for children with bronchiolitis: Implementation of a national guideline.

AIM

High flow nasal cannula (HFNC) therapy is a form of respiratory support used in children with bronchiolitis. A national guideline for the use of HFNC was published in The Netherlands in 2020. We studied the implementation and use of this guideline.

METHODS

We performed a multicentre observational study amongst all hospitals in the North-West part of The Netherlands referring to the same paediatric intensive care unit (PICU). This study consisted of two parts: a comparison of local HFNC protocols to the national guideline and a survey about the use of HFNC amongst paediatricians in the participating centres.

RESULTS

We observed considerable variations between the local protocols and the national protocol, especially regarding criteria to initiate HFNC treatment and weaning practices. Survey results showed that expectations of HFNC widely varied, while the clinical use of HFNC deviated from both the national guideline as well as local protocols, especially for weaning practices and the use of pCO as a parameter for initiation and evaluation of the effect of HFNC.

CONCLUSION

Implementation of the national guideline for HFNC therapy in bronchiolitis was inefficacious, leading to non-uniform clinical practice.
