Association of Language Barriers With Perioperative and Surgical Outcomes

In this systematic review, most of the included studies found associations between English proficiency and multiple perioperative process-of-care outcomes, but fewer associations were seen between English proficiency and clinical outcomes. Because of limitations of the existing research, including study heterogeneity and residual confounding, mediators of the observed associations remain unclear. Standardized reporting and higher-quality studies are needed to understand the impact of language barriers on perioperative health disparities and identify opportunities to reduce related perioperative health care disparities.
