Introduction: Bronchiolitis is the most common cause for hospitalization in the first year of life, with hypoxemia and acute respiratory failure as major determinants leading to hospitalization. In addition, the lack of existing guidelines for weaning and discontinuing supplemental oxygen, including high-flow nasal cannula, may contribute to prolonged hospitalization and increased resource utilization. Methods: This single-center quality improvement initiative assessed the effect of implementing a standardized care process for weaning and discontinuing high-flow oxygen for patients hospitalized with bronchiolitis. Patients aged 1–24 months with bronchiolitis admitted to the general wards or ICU step-down unit from February 1, 2018, and January 31, 2020 were included in the study. Primary outcomes included length of stay and time on supplemental oxygen, with time on high-flow oxygen and length of time in ICU step-down unit as secondary outcomes. Balancing measures included transfer rate to Pediatric Intensive Care Unit, intubation rate, 7- and 30-day readmission rates, and 7- and 30-day ED visits after discharge. Results: Following the standardized care process implementation, the mean length of stay decreased from 60.7 hours to 46.7 hours (P < 0.01). In addition, the mean time on any supplemental oxygen decreased by 47% (P < 0.01), the mean time on high-flow oxygen decreased by 45% (P < 0.01), and the mean time in the ICU step-down unit decreased by 27% (P =< 0.01). Balancing measures remained unchanged with no statistically significant differences. Conclusion: Implementing a standardized care process for weaning and discontinuing high-flow oxygen may reduce the length of stay and resource utilization for patients hospitalized with bronchiolitis.
BACKGROUND Infectious etiologies cause a large portion of pediatric rhabdomyolysis. Among pediatric patients with rhabdomyolysis, it is unknown who will develop acute kidney injury (AKI). We sought to test the hypothesis that a viral etiology would be associated with less AKI in children admitted with rhabdomyolysis than a nonviral etiology. METHODS In this single-center retrospective cohort study, patients <21 years of age admitted with acute rhabdomyolysis from May 1, 2010, through December 31, 2018, were studied. The primary outcome was development of AKI, defined by using the Kidney Disease: Improving Global Outcomes guidelines. The primary predictor was identification of viral infection by laboratory testing or clinical diagnosis. Covariates included age, sex, race, insurance provider, presence of proteinuria and myoglobinuria, and initial creatinine kinase and serum urea nitrogen. Routine statistics and multivariable logistic modeling were performed via SAS 9.4 (SAS Institute, Inc, Cary, NC). RESULTS In total, 319 pediatric patients with rhabdomyolysis were studied. The median age was 13 years. Patients were predominately male (69.9%), non-Hispanic Black (55.2%), and publicly insured (45.1%). We found no difference in the rates of AKI in those with a viral diagnosis versus those without a viral diagnosis (30 of 77 [39.0%] vs 111 of 234 [47.4%]; P = .19). Multivariable analysis revealed that viral diagnosis was not associated with the development of AKI. Patients ≥13 years of age, male patients, and those with proteinuria and elevated serum urea nitrogen on admission had increased odds of developing AKI. CONCLUSIONS In our study, viral rhabdomyolysis did not have lower rates of AKI compared with nonviral etiologies of AKI; therefore, providers should consider continued caution in these patients.
