Model Details
Model Description
- Developed by: Paula Guerrero Castelló and Iker Gutierrez Fandiño.
- Model type: Qwen3.5-derived generative model, fine-tuned for text-only, sentence-level clinical simplification; LoRA weights merged into the base model.
- Language: Spanish (
es) for this task.
- Base model: Qwen/Qwen3.5-0.8B.
- License: The upstream checkpoint is released under Apache 2.0. The metadata identifies that upstream license; this card does not introduce separate terms for the authors' contributions.
Uses
Direct Use
Research and educational exploration of Spanish clinical text simplification. The model can produce draft rewrites of individual clinical sentences for review by health professionals or medical communication specialists.
Downstream Use
It may serve as a component in an assisted authoring tool or as a comparison system in simplification research. Patient-facing deployment requires separate validation of factual fidelity, readability, and suitability for the intended readers.
Out-of-Scope Use
Diagnosis, treatment recommendations, prescribing, emergency triage, or autonomous clinical decisions. The model has not been evaluated for full medical records, other languages, unrestricted medical question answering, or image and video understanding. The base model's multimodal capabilities were not evaluated in this project.
Bias, Risks, and Limitations
- Simplification can omit qualifications, alter negation, numbers, or clinical relationships, or add unsupported explanations.
- Training data comes from clinical trial protocols. Performance may differ on discharge summaries, patient messages, other specialties, or regional varieties of Spanish.
- The test set contains 120 sentences. No demographic, specialty, or literacy-level breakdown is reported.
- The split is random at sentence level. The notebook does not demonstrate document-level separation or a cross-split duplicate audit.
- Automatic text metrics do not establish medical correctness or patient comprehension. No clinical validation or patient comprehension study is reported.
- Biases from the base model and training corpus may remain. Sensitive patient information should not be submitted to a public demo.
