Objective
To determine whether preferred language for care and insurance type are associated with cost among hospitalized children.
Methods
We conducted a retrospective cohort study of inpatients at a freestanding children’s hospital from 1/2011 to 12/2012. Patient clinical and demographic information and hospital costs were obtained from administrative data. Cost differences by language and insurance were calculated based on multivariate generalized linear model estimates, which allowed for language-insurance interaction effects. Models were also stratified by medical complexity and length of stay (LOS) ≥3 days.
Results
Of 19,249 inpatient admissions, 8% preferred Spanish, 6% preferred another language, and 47% had public insurance. Models controlled for LOS, medical complexity, distance from home to hospital, age, asthma diagnosis, and race/ethnicity. Compared to privately-insured English speakers, total hospital costs were significantly higher for publicly-insured Spanish speakers (+$20,211 [95% CI +$7781, +$32,641]), and lower for privately-insured Spanish speakers (−$16,730 [−$28,265, −$5195]) and publicly-insured English speakers (−$4841 [−$6781, −$2902]). A similar pattern was found for pharmacy costs. Differences were most pronounced among children with medical complexity and with LOS ≥3 days.
Conclusions
Hospital costs varied significantly by preferred language and insurance type, even after adjusting for LOS and medical complexity. These differences in the amount of billable inpatient care provided to medically similar patients may represent either under- or over-provision of care on the basis of sociodemographic factors and communication, suggesting problems with care efficiency and equity. Further investigation into the causes may inform development of effective interventions.
