Overview

Retrospective study reveals longer hospital stays among medically complex children from socioeconomically deprived neighborhoods, highlighting systemic health inequities.

Key Points

  • To evaluate the association between neighborhood socioeconomic deprivation and hospital length of stay in children with medical complexity.
  • Conducted a single-center retrospective study of hospitalized patients aged up to 21 years with at least 2 complex chronic conditions discharged between 2016 and 2022 (N = 4,697 encounters from 2,186 patients), excluding neonatal intensive care stays.
  • Mapped patient home addresses to US census-tract data using the Brokamp neighborhood socioeconomic deprivation index as the primary exposure.
  • Employed linear mixed models adjusted for clinical covariates and within-patient clustering to examine the effect on continuous length of stay in days.
  • The median neighborhood deprivation index was 0.33 (IQR, 0.25–0.42) and the overall median hospital length of stay was 3.29 days (IQR, 1.86–6.91).
  • In adjusted analyses, each 0.1-unit increase in the deprivation index was associated with a 1.05-fold increase in length of stay (95% CI, 1.03–1.08).
  • Patients living in more socioeconomically deprived neighborhoods (75th percentile) experienced an estimated 9% increase in length of stay compared to those in less deprived areas (25th percentile).
