Long-term Non-invasive Ventilation Therapies in Children: A Scoping Review

Long-term non-invasive ventilation (NIV) is a common modality of breathing support used for a range of sleep and respiratory disorders. The aim of this scoping review was to provide a summary of the literature relevant to long-term NIV use in children. We used systematic methodology to identify 11,581 studies with final inclusion of 289. We identified 76 terms referring to NIV; the most common term was NIV (22%). Study design characteristics were most often single center (84%), observational (63%), and retrospective (54%). NIV use was reported for 73 medical conditions with obstructive sleep apnea and spinal muscular atrophy as the most common conditions. Descriptive data, including NIV incidence (61%) and patient characteristics (51%), were most commonly reported. Outcomes from sleep studies were reported in 27% of studies followed by outcomes on reduction in respiratory morbidity in 19%. Adverse events and adherence were reported in 20% and 26% of articles respectively. Authors reported positive conclusions for 73% of articles. Long-term use of NIV has been documented in a large variety of pediatric patient groups with studies of lower methodological quality. While there are considerable data for the most common conditions, there are fewer data to support NIV use for many additional conditions.
