Language Barriers In US Healthcare: Research In Limited English Proficiency Patient Experience And Health Outcomes

Abstract

This review covers literature published to the National Library of Medicine from 2010-2021 on the use of Spanish and other non-English languages used in healthcare settings in the United States. Despite the National Culturally and Linguistically Appropriate Service (CLAS) Standards created by the Department of Health and Human Services (HHS) in 2010, it is well-documented that patients with limited English proficiency (LEP) still receive lower quality care. The studies reviewed indicate a lack of standardization in the use of interpretation services and other intervention strategies can increase patient satisfaction, as well as a tendency to underutilize these services when available. Further research must be done on how to promote the use of interpretation services among healthcare providers, how LEP patients navigate topics around mental health, and perspectives of how interpretation services should be used from LEP patients themselves.
