Narrative synthesis #

Bauer & Alegría's systematic review synthesizes 26 studies and 14 empirical studies on how patients' limited English proficiency and interpreter use affect the quality of psychiatric care specifically — a domain where assessment hinges on self-reported symptoms rather than observable signs, so language barriers are theorized to bite harder than in general medicine. The review's synthesized generalization runs in two directions: (1) evaluating a patient in a nonprimary language (no interpreter) can produce incomplete or distorted mental-status assessment and diagnostic disagreement; and (2) use of professional (vs untrained/ad hoc) interpreters improves disclosure of sensitive material, referral to specialty care, and patient satisfaction. The review is explicit that the evidence base is thin and that no included study examined contemporary US psychiatric practice, so this is a directional, mechanism-level thesis rather than a quantified effect — the certainty/GRADE appraisal is left for expert review.

"Evaluation in a patient's nonprimary language can lead to incomplete or distorted mental status assessment. Although both untrained and trained interpreters may make errors, untrained interpreters' errors may have greater clinical impact, compromising diagnostic accuracy and clinicians' detection of disordered thought or delusional content. Use of professional interpreters may improve disclosure in patient-provider communications, referral to specialty care, and patient satisfaction." (Bauer, 2010, p. 765)

"Complementing the robust literature on medical interpreting, a small body of literature suggests that use of professional interpreters during psychiatric encounters facilitates disclosure of sensitive material and leads to greater patient satisfaction and self-understanding, thereby reinforcing the cornerstones of high-quality psychiatric care." (Bauer, 2010, p. 772)

The review also stresses the limits of its own evidence, which the human should weigh in appraisal:

"There is insufficient evidence to determine whether quality of care is compromised and under what circumstances high-quality psychiatric care can prevail in the presence of language barriers." (Bauer, 2010, p. 772)
