Abstract
Acute respiratory failure recalcitrant to conventional management often requires specialized organ-supportive technologies to optimize outcomes. Variation in the availability of these technologies prompted testing of the hypothesis that outcomes and resource use will vary by not only patient characteristics but also hospital characteristics and receipt of organ-supportive technology. Retrospective study of children 0 to 20 years old hospitalized for acute respiratory failure using the 2019 Kids' Inpatient Database. Multivariable regression models identified factors associated with mortality, length of hospitalization, and costs. Of an estimated 75 365 hospitalizations nationally, 97% were to urban teaching hospitals, 57% were of children < 6 years, and 58% were of males. Complex chronic conditions (CCC) existed in 62%, multiorgan dysfunction in 35%, and extreme illness severity in 54%. Mortality was 7%, length of stay 15 days, and hospital costs $77 168. Elevated mortality was associated with cumulative organ dysfunction (odds ratio [OR]:2.31, 95% confidence interval [CI]: 2.22-2.42), CCC (OR: 5.49, 95% CI: 4.73-6.37), transfer, higher illness severity, and cardiopulmonary resuscitation. Lower mortality was associated with extracorporeal membrane oxygenation (OR: 0.36, 95% CI: 0.28-0.47) and new tracheostomy (OR: 0.30, 95% CI: 0.25-0.35). Longer hospitalization was associated with transfer, infancy, CCC, higher illness severity, cumulative organ dysfunction, and urban hospitals. Higher costs accrued with noninfants, cumulative organ dysfunction, private insurance, and urban teaching hospitals. Hospitalizations for pediatric acute respiratory failure incurred substantial mortality and resource consumption. Efforts to reduce mortality and resource consumption should address interhospital transfer, access to organ-supportive technology, and drivers of higher severity-adjusted resource consumption at urban hospitals.
