Implementation of a high-flow nasal cannula management protocol in the pediatric icu

Abstract

BACKGROUND: High-flow nasal cannula (HFNC) therapy is a respiratory modality that has been adopted to support pediatric patients with bronchiolitis. There is no standardized protocol for initiation, escalation, or weaning of HFNC in the pediatric ICU. The aim of this respiratory therapist (RT)-driven quality improvement management protocol was to decrease duration of HFNC. METHODS: An RT-driven HFNC management protocol based on an objective respiratory score was implemented in 2017 at a quaternary care children’s hospital. Subjects included children less than 2 y old admitted to the pediatric ICU with bronchiolitis. All subjects needing HFNC were scored and placed within the protocol as appropriate for age, then weaned or escalated per the scoring tool. Comparison to a pre-intervention control group was performed. Average HFNC duration per subject was used as the primary outcome mea-sure. Protocol compliance was used as a process measure. Noninvasive ventilation use, intubation rate, and 30-d pediatric ICU readmission rate were used as balancing measures. RT satisfaction with HFNC management before and after protocol implementation were measured. RESULTS: Protocol compliance was sustainable and above the goal of 80% after 4 months of protocol implementation. HFNC duration decreased from 2.5 d to 2 days for each subject during planning and then to 1.8 d after protocol imple-mentation. Length of stay (LOS) in the pediatric ICU and hospital LOS decreased from 2.6 d to 2.1 d and from 5.7 d to 4.7 d after protocol implementation, respectively. The use of noninvasive ventilation and the rate of intubation did not change significantly. RTs reported increased involvement in HFNC management decisions and appropriateness on how quickly the team weaned HFNC. CONCLUSIONS: An RT-driven HFNC management protocol was safely implemented in a pediatric ICU and decreased HFNC duration, pediatric ICU LOS, and hospital LOS. It allows the RT to work independently to the highest extent of their scope of practice, leading to improvement in RT job satisfaction.
