Objectives: Critically ill children with bronchiolitis may require neuropharmacologic medications and support for neuro-functional sequelae, but current practices are not well described. We aimed to describe recent trends in neuropharmacology and utilization of neuro-rehabilitation resources in mechanically ventilated children with bronchiolitis. Design: Analysis of the multicenter Pediatric Health Information System database. Setting: Forty-seven U.S. children’s hospitals. Patients: PICU patients less than 2 years old with bronchiolitis undergoing mechanical ventilation between 2006 and 2015. Interventions: None. Annual rates of utilization of neuropharmacologic medications (sedatives, analgesics, etc) and of neuro-rehabilitation services (physical therapy, neurologic consultation, etc) over the 10-year study period were compared. Measurements and Main Results: Neuropharmacologic medications prescribed on greater than or equal to 2 days were extracted. Utilization of MRI of the brain, neurologic consultation, swallow evaluation, occupational therapy, and physical therapy was also extracted. Among 12,508 subjects, the median age was 2.8 months, ~50% had comorbid conditions, and the median duration of mechanical ventilation was 7 days. The percentage of children prescribed greater than or equal to five drugs/drug classes increased over the study period from 36.5% to 55.8% (p < 0.001). There were significant increases over time in utilization of 10 of the 15 individual drugs/drug classes analyzed. More than half of subjects (6,294 [50.3%]) received at least one service that evaluates/treats neurologic morbidity. There were significant increases in the use of greater than or equal to one service (36.3% in 2006 to 59.6% in 2015; p < 0.001) and in the use of greater than or equal to two services (20.8% to 34.8%; p < 0.001). Utilization of each of the five individual resources increased significantly during the study period, but use of vasoactive medications and mortality did not. Conclusions: Prescription of neuropharmacologic agents increased over time using metrics of both overall drug burden and specific drug usage. Concurrently, the utilization of services that evaluate and/or treat neurologic morbidity was common and also increased over time.
