Weaning Humidified High Flow Oxygen Therapy among Paediatric Patients: An Integrative Review of Literature.

Problem: The paucity of up-to-date recommendations and evidence-based models, whether it is physician-initiated or initiated by other healthcare professionals, for humidified high flow oxygen therapy among children.

Eligibility Criteria: The inclusion criteria included the following: 1) use of high flow oxygen therapy (≥15 L/min); 2) published studies from the year 2000 and onwards; 3) research article in a peer-reviewed journal; 4) studies conducted in a hospital setting involving paediatric patients <18 years old; 5) availability of full article online.

Sample: From March to April 2018, electronic databases such as PubMed, Cumulative Index of Nursing and Allied Health Literature, Excerpta Medica Database, Cochrane Library, Joanna Briggs Institute Library of Systematic Reviews, SCOPUS, Ovid, Informit, and Google Scholar were accessed. The systematic search initially yielded 41 studies.

Results: Eventually, three eligible studies were reviewed and appraised. Overarching themes were identified: 1) the lack of weaning standards; 2) the limited focus on young population in intensive care settings; and 3) the paucity of weaning models.

Conclusion: The lack of studies suggested that this is a fertile area for research. In this light, this paper challenged researchers, clinicians, and experts to develop evidence-based standards and models of weaning towards efficient and better quality of care.

Implication: This review may lead to the development of nurse-led or nurse-initiated weaning protocols to enable timely weaning intervention for children and thus reduce the need for prolonged oxygen use. Furthermore, this may also instigate an economic evaluation of a nurse-lead weaning against current models of medically lead weaning.
