"It's the difference between life and death": The views of professional medical interpreters on their role in the delivery of safe care to patients with limited English proficiency.

Our study found that professional medical interpreters view their work as integral to the delivery of safe care to patients with LEP. In order to effectively engage in patient safety efforts together, interpreters and providers require a mutual understanding of their roles. Team hierarchy and limited provider knowledge of the role of interpreters can introduce safety concerns. In addition, interpreters describe a tension between "speaking up" about patient safety and the need for interpreters to remain impartial when facilitating communication. Healthcare institutions, providers, and interpreters must engage in discussion on how to best to "speak up" and integrate interpreters into safety efforts. Importantly, the benefits of partnering with interpreters can only be realized when providers consistently use their services.
