Enterprise AI Analysis
Evaluating human-in-the-loop strategies for artificial intelligence-enabled translation of patient discharge instructions: a multidisciplinary analysis
Machine translation (MT) supported by artificial intelligence (AI) can improve linguistically-concordant patient care. This study compared three translation modalities for free-text inpatient discharge instructions across six languages: AI-generated (ChatGPT-40), professional linguists, and human-in-the-loop (AI-generated, post-edited by professional linguists). Human-in-the-loop (HITL) translations achieved comparable or superior outcomes to professional translations, especially for digitally underrepresented languages, with significantly reduced translation times (7.1 min vs. 16.8 min, p < 0.001) and were most frequently preferred (46.5% vs. 28.4%). ChatGPT-40 alone showed variable performance, particularly poor for Armenian and Somali. HITL strategies offer a safe, efficient, and equitable approach for AI-enabled translation in clinical practice, guided by multidisciplinary input.

The study compared three translation modalities for free-text pediatric inpatient discharge instructions into Arabic, Armenian, Bengali, simplified Chinese, Somali, and Spanish: ChatGPT-40 (Version 2024-11-20), human-in-the-loop (AI-generated, post-edited by professional linguists), and professional linguist (current reference standard). Forty-two evaluators (linguists, clinicians, family caregivers) rated translations using a 5-point Likert scale (1–5; higher is better) across five domains: adequacy, fluency, meaning, severity, and overall quality. Interrater reliability was moderate to good. Translation times were also recorded.
ChatGPT-40 Performance: Variable, with poorest ratings for digitally underrepresented languages (Armenian, Somali), but comparable to professional for Bengali and Spanish. Significant deficits in accuracy and quality were noted for languages with sparse linguistic datasets.
Human-in-the-loop (HITL) Performance: Consistently comparable or better than professional translations across most languages, achieving higher overall quality for Armenian, Bengali, and Spanish. Most frequently preferred modality (46.5% overall).
Efficiency: HITL translations were significantly faster (mean 7.1 min) than professional translations (mean 16.8 min) (p < 0.001).
Safety and Equity: Heterogeneity of MT quality necessitates human oversight. HITL improves AI outputs, making MT safer and more equitable, especially for vulnerable populations.
Clinical Workflow: HITL approaches are more practical for time-sensitive communications like discharge instructions than conventional translation services.
Policy Considerations: Federal policies mandate qualified translators for accuracy-essential or complex documents. Fully automated MT should be limited to low-risk, non-clinical activities and rigorously validated languages. Cautious HITL introduction is appropriate for a broader range.
Multidisciplinary Input: Essential to define acceptable workflows, protect patient privacy, and ensure safety. Linguists, clinicians, and family caregivers provide complementary perspectives, with linguists focusing on adequacy/fluency and clinicians/caregivers on clinical meaning.
46.5%
of evaluators preferred Human-in-the-Loop translations, highlighting its superior user acceptance compared to professional (28.4%) or ChatGPT-40 (13.6%) alone.

Final High-Quality Translation
| Feature | ChatGPT-40 (AI Only) | Human-in-the-Loop (AI + Human) | Professional Linguist |
|---|---|---|---|
| Overall Quality (Avg. Likert) | Variable (Poor for Armenian/Somali) | Comparable/Better (e.g., Armenian +0.3 pts) | Reference Standard |
| Translation Time (Avg. min) | ~1 min | 7.1 min (57% faster) | 16.8 min |
| User Preference | Least Preferred (13.6%) | Most Preferred (46.5%) | Mid-Preferred (28.4%) |
| Equity for Underrepresented Languages | Significant Deficits | Improved Outcomes | Consistent |
Impact on Armenian Translations
For Armenian, a digitally underrepresented language, ChatGPT-40 received a mean overall quality rating of 2.4 (out of 5), significantly lower than professional translations (3.6). However, the Human-in-the-Loop approach elevated quality to 3.9, exceeding professional translations (p=0.01) and demonstrating how human oversight can mitigate AI limitations for underserved linguistic communities.

Phased Implementation Roadmap
A strategic approach to integrate AI-enabled translation with human oversight into your clinical operations.
Phase 1: Pilot & Validation
Begin with a pilot program for low-risk, high-volume communications (e.g., appointment reminders) in a single language. Involve linguists, clinicians, and caregivers in a structured validation process to establish performance benchmarks and identify language-specific needs.
Phase 2: Workflow Integration
Integrate HITL workflows for time-sensitive documents like discharge instructions in validated languages. Develop clear protocols for post-editing and quality assurance. Provide comprehensive training for linguists and clinical staff on AI tools and ethical guidelines.
Phase 3: Expansion & Monitoring
Gradually expand to additional languages and communication types, prioritizing those with significant patient populations. Implement continuous monitoring of translation quality, efficiency, and user feedback. Establish a multidisciplinary governance committee for ongoing oversight and policy refinement.
