Appropriate use of medical interpreters

Area of Science:

• Medical communication
• Health equity
• Linguistics in healthcare

Background:

• Over 25 million Americans have limited English proficiency, facing barriers to healthcare access.
• Limited English proficiency is linked to adverse health outcomes, including drug complications and decreased patient satisfaction.
• Title VI of the Civil Rights Act mandates interpreter services for these patients, though reimbursement is often lacking.

Purpose of the Study:

• To highlight the importance of professional medical interpreters for patients with limited English proficiency.
• To compare the effectiveness of professional interpreters versus ad hoc interpreters.
• To provide guidelines for effective interpreter use in clinical settings.

Main Methods:

• Review of existing literature and guidelines on medical interpreter services.
• Comparison of error rates, confidentiality breaches, and patient outcomes between professional and ad hoc interpreters.
• Analysis of best practices for clinician-interpreter-patient interaction.

Main Results:

• Professional interpreters are significantly more effective than ad hoc interpreters (family, friends, untrained staff).
• Ad hoc interpreters increase the risk of errors, confidentiality violations, and poor patient outcomes.
• Children should not be used as interpreters except in emergencies.

Conclusions:

• Professional interpreters, whether in-person or via phone, enhance patient satisfaction, adherence, and health outcomes.
• Effective interpreter use can reduce adverse events and malpractice risk.
• Bilingual clinicians, professional interpreters, phone services, or trained staff are viable options for ensuring effective communication.
