Implicit Geographic Inference in LLM Medical Triage: Language-Driven Disparities in Emergency Recommendations

arXiv:2606. 01204v1 Announce Type: cross Abstract: We investigate whether large language models produce different medical triage recommendations for identical symptoms based solely on the language of the patient prompt.

MIRA: A Bilingual Benchmark for Medical Information Response Audit

MIRA is a bilingual benchmark that evaluates whether large language models (LLMs) provide consistent medical information across different user phrasings, languages, and health literacy levels. It contains 4,320 prompts derived from 60 medically reviewed low‑risk health questions and reveals that models tend to omit key information and offer fewer concrete next steps when responding to low health‑literacy signals, a phenomenon termed Differential Information Dilution (DID). A knowledge‑guided mitigation prompt can reduce this dilution for most models, notably improving Claude and Qwen.

CrisiLangs: A Multilingual Resource for Crisis Warning Generation

CrisiLangs is a multilingual extension of the CrisiText dataset, adding Italian, Bulgarian, German, and Greek translations of warning messages for 1,000 crisis events, resulting in 5,000 event‑message pairs across five languages. The resource was used to fine‑tune a multilingual model, which outperformed a zero‑shot baseline on ROUGE‑L, BLEU, and BERTScore in every language and configuration. Human preference studies showed that low decoding temperatures were favored across all languages, while the impact of emergency guidelines varied by language.

One Confidence Threshold, Unequal Coverage: Language Gaps in Typed Decision Interfaces and How Translating Inputs Reduces Them

The study evaluates whether a single confidence threshold in typed decision interfaces treats all languages equally. Using 1,000 items in 51 languages across three vendors, it finds that English consistently achieves higher coverage—clearing the 0.9 threshold 8.6–11.7 percentage points more often than other languages—despite similar accuracy. Even when thresholds are re‑weighted or calibrated per language, the gap persists, and translating inputs into English reduces but does not eliminate it. The authors recommend reporting per‑language coverage at the operating threshold.

HerHealthEval: Evaluating Multilingual and Register-Sensitive Understanding of Women's Health Communication

HerHealthEval is a controlled evaluation framework that tests multilingual understanding of women's-health communication across English, French, and Modern Standard Arabic. It provides six communicative forms—canonical, clinical, layperson, indirect or hedged, emotionally concerned, and deliberately under-specified—each conveying the same clinical concern except the under-specified form omits details to assess clarification needs. The study evaluates multilingual instruction models and QLoRA-adapted variants on tasks such as concern classification, risk calibration, clarification behavior, parse compliance, and cross-form consistency, revealing that high aggregate accuracy can mask safety-relevant failures and that language-invariant risk labels improve performance.

Counterfactual Auditing of Bias in Open-Source Large Language Models for Clinical Triage

The study evaluates counterfactual bias in ten open‑source large language models (LLMs) for pediatric Emergency Severity Index (ESI) prediction. By creating paired clinical vignettes that differ only in demographic or socioeconomic variables, the authors measure shifts in acuity assignment, finding that counterfactual sensitivity varies widely across model families and sizes. A fine‑tuned Qwen2.5‑7B model exhibited the lowest sensitivity, while larger or medical‑domain models sometimes showed greater shifts, highlighting the need for fairness assessment before clinical deployment.

EviSI: An Evidence-Based Evaluation Agent for Simultaneous Interpreting

EviSI is an evidence‑based evaluation agent for low‑latency simultaneous speech‑to‑speech translation. It combines Multidimensional Quality Metrics with interpreter‑developed criteria, using shared source evidence to assess four dimensions—Anchor, Event, Logic, and Fluency—while deduplicating verified errors before scoring. On English‑to‑Chinese and Chinese‑to‑English data, EviSI’s rankings correlate strongly with human judgments, outperforming BLEU and COMET, and its multilingual extension maintains these correlations across five language directions.
