Outcomes Before and After Adoption of a Ward-Based High-Flow Nasal Cannula Protocol Interrupted time series analysis, examining the trend of an outcome three seasons before and three seasons after protocol adoption, with the adoption season denoted by a dotted interruption line. Four sub-figures compare the following outcomes among patients hospitalized for bronchiolitis: (A) the proportion of patients who required intensive care unit (ICU) admission; (B) the mean ICU length of stay per 100 patients; (C) the mean total length of stay for a patient’s entire hospitalization; (D) the proportion of patients who required mechanical ventilation. Error bars represent the 95% confidence interval.
