Sociodemographic factors associated with tracheostomy and mortality in bronchopulmonary dysplasia

Abstract

AbstractObjectivesWe sought to investigate how race, ethnicity, and socioeconomic status relate to tracheostomy insertion and post‐tracheostomy mortality among infants with bronchopulmonary dysplasia (BPD).MethodsThe Vizient Clinical Database/Resource Manager was queried to identify infants born ≤32 weeks with BPD admitted to US hospitals from January 2012 to December 2020. Markers of socioeconomic status were linked to patient records from the Agency for Healthcare Research and Quality's Social Determinants of Health Database. Regression models were used to assess trends in annual tracheostomy insertion rate and odds of tracheostomy insertion and post‐tracheostomy mortality, adjusting for sociodemographic and clinical factors.ResultsThere were 40,021 ex‐premature infants included in the study, 1614 (4.0%) of whom received a tracheostomy. Tracheostomy insertion increased from 2012 to 2017 (3.1%–4.1%), but decreased from 2018 to 2020 (3.3%–1.6%). Non‐Hispanic Black infants demonstrated a 25% higher odds (aOR 1.25, 1.09–1.43) and Hispanic infants demonstrated a 20% lower odds (aOR 0.80, 0.65–0.96) of tracheostomy insertion compared with non‐Hispanic White infants. Patients receiving public insurance had increased odds of tracheostomy insertion (aOR 1.15, 1.03–1.30), but there was no relation between other metrics of socioeconomic status and tracheostomy insertion within our cohort. In‐hospital mortality among the tracheostomy‐dependent was 14.1% and was not associated with sociodemographic factors.ConclusionsDisparities in tracheostomy insertion are not accounted for by differences in socioeconomic status or the presence of additional neonatal morbidities. Post‐tracheostomy mortality does not demonstrate the same relationships. Further investigation is needed to explore the source and potential mitigators of the identified disparities.
