OBJECTIVES: To describe the practice of high-flow nasal cannula (HFNC) use in the pediatric ward setting across North America. METHODS: A survey was distributed through the Pediatric Research in Inpatient Settings Network, which represents 114 hospital sites. Questions included indication for HFNC use, flow and oxygen parameters, guideline availability, and use of outcomes measures. RESULTS: There was a response rate of 68% to the survey from sites representing all regions from the United States. Thirty-seven sites (48%) used HFNC in the pediatric ward setting. All 37 sites used HFNC for patients with bronchiolitis. All children’s hospital sites providing HFNC on the wards had an on-site ICU, compared with only 60% of non–children’s hospital sites (P = .003). Seventy-six percent of sites used local protocols, including parameters for patient assessment, initiation, weaning, and feeding practices. CONCLUSIONS: HFNC is used outside the ICU in nearly 50% of responding hospitals, with variation related to flow rate, feeding, and protocol use. HFNC is used for management of acute respiratory distress due to bronchiolitis, asthma, and pneumonia. Study findings suggest that HFNC is often used by pediatric hospitalists, but its use across North American hospitals remains variable and based on local consensus.
Background Methods of sustaining the deimplementation of overused medical practices (i.e., practices not supported by evidence) are understudied. In pediatric hospital medicine, continuous pulse oximetry monitoring of children with the common viral respiratory illness bronchiolitis is recommended only under specific circumstances. Three national guidelines discourage its use for children who are not receiving supplemental oxygen, but guideline-discordant practice (i.e., overuse) remains prevalent. A 6-hospital pilot of educational outreach with audit and feedback resulted in immediate reductions in overuse; however, the best strategies to optimize sustainment of deimplementation success are unknown. Methods The Eliminating Monitor Overuse (EMO) trial will compare two deimplementation strategies in a hybrid type III effectiveness-deimplementation trial. This longitudinal cluster-randomized design will be conducted in Pediatric Research in Inpatient Settings (PRIS) Network hospitals and will include baseline measurement, active deimplementation, and sustainment phases. After a baseline measurement period, 16–19 hospitals will be randomized to a deimplementation strategy that targets unlearning (educational outreach with audit and feedback), and the other 16–19 will be randomized to a strategy that targets unlearning and substitution (adding an EHR-integrated clinical pathway decision support tool). The primary outcome is the sustainment of deimplementation in bronchiolitis patients who are not receiving any supplemental oxygen, analyzed as a longitudinal difference-in-differences comparison of overuse rates across study arms. Secondary outcomes include equity of deimplementation and the fidelity to, and cost of, each deimplementation strategy. To understand how the deimplementation strategies work, we will test hypothesized mechanisms of routinization (clinicians developing new routines supporting practice change) and institutionalization (embedding of practice change into existing organizational systems). Discussion The EMO trial will advance the science of deimplementation by providing new insights into the processes, mechanisms, costs, and likelihood of sustained practice change using rigorously designed deimplementation strategies. The trial will also advance care for a high-incidence, costly pediatric lung disease. Trial registration ClinicalTrials.gov,NCT05132322. Registered on November 10, 2021.
Having a greater index of suspicion for abuse may mitigate missed opportunities. With variability of medical training in child abuse, the factors we identified can be used as learning objectives for continuing medical education.
