| Sumario: | Background: The underuse of interpreters for limited English proficiency (LEP) patient encounters is pervasive, particularly in the emergency department (ED). Objective: To measure the outcome of strategies to improve the use of interpreters by ED providers. Methods: Pre- and post- intervention evaluation of the unmet need for language assistance (LA) in a public ED. Informed by the Behavior Change Wheel (BCW), strategies included: education, training, technology-based facilitators, local champions and environmental cues. Results: Pre-intervention, of the 110 patient charts with interpreter requests, 17 (15.5%) had documentation of an interpreter-mediated encounter or were seen by a certified bilingual provider (unmet need = 84.5%). Post intervention, of the 159 patient charts with interpreter requests, 47 (29.6%) had documentation of an interpreter-mediated encounter or were seen by a certified bilingual provider (unmet need = 70.4%), difference + 0.14 (95% CI = 0.03-0.23). Conclusion: In this pilot study, we found a statistically significant increase in the met need for language assistance.
