Examining the association between professional language interpreter services and intensive care unit utilization among patients with non-English language preference: Evidence from a large U.S. hospital

Abstract

ObjectiveTo examine the healthcare utilization of patients with non-English language preference (NELP) who utilized a professional language interpreter (PLI) in the intensive care unit (ICU) compared to similar patients with NELP who did not utilize a PLI in the ICU. MethodsSingle center cohort study of patients with NELP with at least one ICU admission a large academic medical center in the U.S. Midwest (1/1/2008-12/31/2022). The first model examined ICU length-of-stay (LOS) using a negative binomial and the second model examined whether a patient was readmitted to the ICU using a logistic regression with each model controlling for PLI utilization and covariates. ResultsPatients with NELP who utilized a PLI in the ICU had 0.87-days longer in the ICU (p<0.01) and had a 46% decreased odds of being readmitted to the ICU (p<0.01) than a comparable patient with NELP who did not utilize a PLI in the ICU. ConclusionProviding patients with NELP with access to a PLI in the ICU can improve patient outcomes and reduce language barriers. Practice implicationsThese results can provide the justification to potentially increase PLI staffing levels or increase the access to existing PLIs for more patients with NELP in ICUs.
