The article by Cheri Wilson, "Patient Safety and Healthcare Quality: The Case for Language Access", highlights the challenges of providing Culturally and Linguistically Appropriate Services (CLAS) to patients with Limited English Proficiency (LEP). As the US pursues high-value, high-performance healthcare, our ability to meet the needs of our most vulnerable will determine whether we succeed or fail in the long run. With the implementation of the Affordable Care Act (ACA), this is more important than ever before, as it is estimated that the newly insured are more likely to be minority and less likely to speak English than their currently insured counterparts. As such, we must create a safe, high-quality healthcare system for all, especially in this time of incredible healthcare transformation and unprecedented diversity. Improving Patient Safety Systems for Patients With Limited English Proficiency: A Guide for Hospitals provides a blueprint for achieving this goal, and Massachusetts General Hospital (MGH) is taking action.
