Currently, AI technology is reshaping the healthcare industry at an unprecedented pace. Guided by the core philosophy of "AI services for all," the Second Affiliated Hospital Zhejiang University School of Medicine (SAHZU) has strategically planned around data elements, exploring the application of AI technology and the upgrading of medical service models to establish an open, collaborative, and win-win panoramic intelligent hospital.

"Here, AI is not just a super assistant for doctors but also the core engine driving the innovation of medical service models. The 'computing power-model-data' trinity model developed by us provides a replicable 'SAHZU Solution' for AI transformation in the healthcare industry," said Academician Wang Jian'an, Chairman of SAHZU.

In the field of cardiac interventional therapy, a technological revolution is rewriting the rules of diagnosis and treatment. Traditionally, assessing coronary blood flow required invasive wire procedures or multi-angle imaging, which were not only complex but also time-consuming and costly.

Recently, the FLAVOUR II study led by Academician Wang Jian'an and Professor Hu Xinyang of SAHZU - featuring an AI-powered non-invasive automated coronary flow measurement system and precise stent implantation—was simultaneously announced at the American College of Cardiology Annual Meeting and published in The Lancet. The study is the first to demonstrate that AI-powered quantitative flow ratio technology matches the clinical efficacy of traditional intravascular ultrasound in guiding interventional therapy. Moreover, it requires only a single-angle image and completes the entire analysis within one minute, significantly improving diagnostic efficiency.

Beyond this, the technology reduces unnecessary stent implantations by 11.5%, as medication alone suffices for these patients. This critical finding lowers the risk of invasive procedures for patients and saves medical resources such as ultrasound catheters and stents. The successful application of this technology marks a solid step forward for China in the field of AI-powered healthcare.

On the computer of Dr. Zhu, a clinical specialist in the Department of Colorectal Surgery, the AI High-Risk Patient Alert and Tracking System (APTS) is flashing warning messages.

Launched earlier this year, the APTS system uses AI as its engine to accurately identify high-risk patients, enabling comprehensive tracking and personalized management. Prof. Xiang Peng, Director of Intelligence and Information Department explained that the APTS system automatically analyzes nearly 30,000 outpatient, emergency, inpatient, and medical examination records daily. Leveraging the semantic understanding capabilities of the independently developed Zhejiang University Qizhen Medical Large Model, its sensitivity in precise data extraction reaches 99.5%.

"AI can not only capture characteristic signals such as malignant tumors in pathological images but also identify hidden risks. Once detected, the system automatically alerts clinical specialists (doctors), who verify the information and immediately contact high-risk patients by phone," said Vice President Wang Liangjing.

An 82-year-old patient, Mr. Wang, is one of the beneficiaries of the APTS system. After undergoing tests for black stools and rectal bleeding, he returned home. When the system quickly flagged his results, Dr. Zhu promptly called him back to the hospital.

"Right after we got home, the hospital called three times, saying my father's test results were concerning. They kindly booked us an appointment with expert Dr. Xiao Qian and arranged immediate surgery. Now, we've recovered and returned home. We're very grateful for the hospital's timely reminder-it was a tremendous help," Mr. Wang's daughter said.

Statistics show that in just three months since its launch, APTS has accurately identified 18,000 high-risk patients, turning "early detection, early intervention" from a slogan into reality. Like a tireless "medical sentinel," it breaks the passive model of traditional healthcare where "patients wait for their conditions to worsen, and doctors wait for patients to come to them," making medical services more compassionate and efficient.

As the deep integration of AI and healthcare becomes not a "choice" but a "necessity," SAHZU is proving through practice: the warmth of technology lies in enabling every patient to equally access precision medicine, and the value of intelligence lies in shifting the healthcare system from "disease treatment" to "health protection." This may well be the ultimate vision of a "panoramic intelligent hospital"- making AI an "invisible guardian" on everyone's health journey and ensuring the benefits of medical transformation reach more people.
