Understanding the use and outcomes of high-flow nasal cannula among infants admitted to Canadian hospitals with bronchiolitis (CanFLO): a protocol for a multicentre, retrospective cohort study.

INTRODUCTION: Bronchiolitis is the most common viral lower respiratory tract infection in children under 2 years of age. Respiratory support with high-flow nasal cannula (HFNC) is increasingly used in this patient population with limited understanding of the patients most likely to benefit and considerable practice variability of use. This study aims to understand the factors associated with failure of HFNC support among patients with bronchiolitis and to describe the current practice variations of HFNC use in patients with bronchiolitis in Canadian hospitals including fluid management and parameters to initiate, escalate and discontinue HFNC support. METHODS AND ANALYSIS: This is a multicentre retrospective cohort study including hospitalised patients aged 0-24 months with bronchiolitis requiring support with HFNC between January 2017 and December 2021. Clinical data will be collected from patient medical records from Canadian hospitals (n=12), including academic and community centres. HFNC failure will be defined as the need for escalation to non-invasive or invasive mechanical ventilation. Factors associated with HFNC failure will be analysed using logistic regression. Descriptive statistics will be used to describe practice variations of HFNC utilisation and management. ETHICS AND DISSEMINATION: Approval from the Research Ethics Boards (REBs) has been obtained for each participating study site prior to onset of data collection including Clinical Trials Ontario for all Ontario hospital sites and REBs from British Columbia Children's Hospital, Stollery Children's Hospital, Montreal Children's Hospital and CHU Sainte-Justine. Study results will be disseminated through presentation at national/international conferences and publication in high-impact, peer-reviewed journals.

Increasing Access to Developmental Services for Children with Autism Spectrum Disorder: The Pediatric Developmental Passport Pilot Randomized Trial.

The pediatric developmental passport was created to aid service navigation for children with autism spectrum disorder (ASD). A pilot-randomized-control trial was conducted at two developmental clinics. The intervention group received the Passport card versus the control group who received the placebo card. Primary outcome was the proportion of families who contacted ASD services 1-year following diagnosis. Of 40 families, 95% in the intervention group contacted services versus 70% in the control (p = 0.04). All families at the academic site contacted services; at the community site 90% in the intervention group contacted versus 40% in the control (p = 0.02). The Passport shows promise aiding families of children with ASD in service navigation, particularly at community clinics where specialist follow-up is not readily available.
