FIGURE 1.
Incidence of bronchiolitis hospitalizations and all hospitalizations per 1000 children in the United States, 2000–2016. Overall, there was a significant decrease in the incidence of bronchiolitis hospitalization (25% decrease; Ptrend < .001) and all hospitalizations (31% decrease; Ptrend < .001) from 2000 through 2016. Likewise, there was a significant decrease in the incidence in infants (32% decrease; Ptrend < .001). By contrast, there was a significant increase in children with complex chronic conditions (70% increase; Ptrend < .001).
