Abstract
STUDY OBJECTIVES: The aim of this study was to measure changes in adherence to noninvasive ventilation (NIV) in children during the first year of the COVID-19 pandemic. METHODS: Retrospective chart review of children (0-18 years) using home NIV through the Stollery's Pediatric NIV program in Edmonton, Canada during March 2019 to March 2021. Demographics, clinical characteristics, and adherence information from machine downloads were collected prior to and during the first year of the COVID-19 pandemic. Paired t tests and Chi-square compared adherence prepandemic and during pandemic and repeated analysis of variance tests compared adherence pre- and 0-6 and 6-12 months during pandemic. RESULTS: Eighty-two children met inclusion criteria (62% male; age 8.6 ± 4.6 years). Overall, there were no changes in NIV adherence during pandemic (average NIV minutes pre- and during pandemic of 390 ± 219 and 405 ± 300 minutes, respectively). When separated into increased vs decreased adherence groups, adherence differences pre- compared to during pandemic became significant, with no differences across demographic/clinical variables or prepandemic adherence. There were no changes in NIV adherence during the initial 6 months of pandemic compared to prepandemic, but NIV use significantly increased by 9-57 minutes during the following 6-12 months. Bilevel positive airway users had longer NIV use than continuous positive airway pressure users at all time points, with an overall increasing trend over time. CONCLUSIONS: Despite the significant life disruption created by COVID-19 and changes to virtual care, children using home NIV maintained adequate adherence. Qualitative research is needed to understand the nuances of using NIV during the pandemic and potential advantages of virtual care for support of these children and families.
