Evaluating a Large Language Model in Translating Patient Instructions to Spanish Using a Standardized Framework

In this cross-sectional study, GPT-4o generated Spanish translations of pediatric patient instructions that were comparable in quality to those by professional human translators as evaluated using a standardized framework. While human review of LLM translation remains essential in health care, these findings suggest that GPT-4o could reduce the translation workload for Spanish, potentially freeing resources to support languages of lesser diffusion.
