233 Hospitals in Chongqing Adopted the Same AI — and the Happiest Users Are Seniors

A new AI healthcare assistant called Yu Xiaojian (渝小健) has been deployed across all 233 public hospitals in Chongqing, from top-tier tertiary hospitals to county-level facilities. Launched on July 17, 2026 after an 8-month pilot serving over 2 million visits, the AI handles the entire patient journey — pre-visit triage, in-hospital navigation, and post-visit report interpretation. The most surprising outcome: elderly patients, who typically struggle with digital healthcare tools, are its happiest users.

A new AI healthcare assistant called Yu Xiaojian (渝小健) has been deployed across all 233 public hospitals in Chongqing, from top-tier tertiary hospitals to county-level facilities. Launched on July 17,

The AI addresses three core pain points in China's hospital experience: (1) Pre-visit — patients describe symptoms by voice or text, and the AI matches them to the right department and doctor. (2) During-visit — a cloud companion guides patients through check-in, queuing, exams, payment, and medication pickup with automatic phone reminders. (3) Post-visit — lab reports are pushed automatically with plain-language explanations of abnormal indicators.

What makes Yu Xiaojian stand out is its Sichuan-Chongqing dialect support — elderly patients can speak naturally in their local dialect instead of struggling with Mandarin or typing. At the Second Affiliated Hospital of Chongqing Medical University, the 8-month pilot served over 200,000 visits, with one-third from elderly patients — an unusually high adoption rate for a digital health product, where 10% senior user share is considered excellent.

Technically, the system uses a tiered deployment: 32 top-tier hospitals run the full version with real-time lab syncing and deep AI interpretation, while the remaining hospitals use a simplified agent for remote consultation and information lookup. The underlying infrastructure is built on the 'Digital Chongqing' data platform, with Ant Group's AI large model providing reasoning capabilities and each hospital opening its local business systems.
