Tech giants lead China’s advances in health services

BEIJING — Amazon and two other U.S. titans are trying to shake up health care by experiment­ing with their own employees’ coverage. By Chinese standards, they’re behind the curve.

Technology companies like Alibaba and Tencent have made health care a priority for years, and are using China as their laboratory. After testing online medical advice and drug-tracking systems, they are now focused on a more advanced tool: artificial intelligen­ce.

Their aggressive push underscore­s the difference­s between the health care systems in China and the United States.

Chinese hospitals are overburden­ed, with just 1.5 doctors for every 1,000 people — barely half the figure in the United States. Along with a rapidly aging population, China also has the largest number of obese children in the world, as well as more diabetes patients than anywhere else.

The companies’ technologi­cal push is encouraged by the government. Beijing has said it wants to be a leader in AI by 2030 and pledged to take on the United States in the field. While officials have emphasized the use of artificial intelligen­ce in areas like defense and self-driving cars, they have also aggressive­ly promoted its use in health care.

Alibaba and Tencent, which already dominate China’s e-commerce and mobile payments sectors, are at the forefront. Among their goals: building diagnostic tools that will make doctors more efficient.

Amazon and its partners, JPMorgan Chase and Berkshire Hathaway, see technology as a way to provide simplified, affordable medical services. Although the alliance is still in the early stages, it could create online services for medical advice or use its overall heft to negotiate for lower drug prices.

“It’s fair to say that across the board, the Chinese tech companies have all embraced being involved in and being active in the health care space, unlike the U.S., where some of them have and some have not,” said Laura Nelson Carney, an Asia-Pacific health care analyst at Bernstein Research.

“Few of them have made moves as big as in China,” Carney said, referring to Alibaba and Tencent’s American

rivals.

Those big moves have had varying degrees of success.

In 2014, Alibaba announced a “future hospital” plan intended to make treatment more efficient by allowing patients to consult with doctors online and order drugs via the Internet. But two years later, Chinese regulators stopped the sale of over-thecounter drugs on Tmall, Alibaba’s e-commerce website. They also suspended a drug-monitoring system the company had created. And last year, search engine company Baidu scrapped its Internet health care service, which allowed patients to book medical appointmen­ts through an app, in a bid to focus solely on AI.

But some of the more recent initiative­s have made inroads. Last year, Alibaba’s health unit introduced AI software that can help interpret CT scans and an AI medical lab to help doctors make diagnoses. About a month later, Tencent unveiled Miying, a medical imaging program that helps doctors detect early signs of cancer, in the southweste­rn region of Guangxi. It is now used in nearly 100 hospitals across China.

Tencent has also invested in WeDoctor Group, which has opened its own take on Alibaba’s “future hospital” in northweste­rn China. The service allows patients to video chat with doctors and fill their prescripti­ons online.

Advances in artificial

intelligen­ce have already been transforma­tive for China’s overworked doctors.

Dr. Yu Weihong, an ophthalmol­ogist at Peking Union Medical College Hospital, said she used to take up to two days to analyze a patient’s eyes by scrutinizi­ng grainy images before discussing her findings with colleagues and writing up a report. Artificial intelligen­ce software being tested by the hospital helps her do all that dramatical­ly faster.

“Now, you don’t even need a minute,” she said.

The software has been developed by VoxelCloud, a startup that has raised about $28.5 million from companies including Tencent and Menlo Park venture capital firm Sequoia Capital. It specialize­s in automated medical image analysis, helping eye doctors like Yu screen patients for diabetic retinopath­y, the leading cause of blindness among China’s working-age population.

There are just 20 eye doctors for every million people here, a third of the proportion in the United States. In April, Beijing announced an ambitious plan for the country’s 110 million diabetics to undergo

eye tests.

“It’s impossible for one person to read that many images,” Yu said.

Ding Xiaowei, whose grandparen­ts were doctors, founded VoxelCloud in 2016, three months after completing his doctorate in computer science at UCLA. The company, which has offices in Los Angeles and the Chinese cities of Shanghai and Suzhou, is awaiting the green light from China’s version of the Food and Drug Administra­tion for five diagnostic tools for CT scans and retina disease.

The sheer size of China’s population — nearly 1.4 billion people who could provide a vast number of images to feed into their systems — provides a potential advantage for the developmen­t of artificial intelligen­ce. Also helping: China has fewer concerns about privacy, allowing for easier collection of data that could result in smarter and more efficient systems. Regulation here isn’t as strict as in the United States, either.

In all, more than 130 companies are applying AI in ways that could increase the efficiency of China’s health care system, according to Yiou Intelligen­ce, an industry consultanc­y in Beijing. They range from behemoths like Alibaba and Tencent to domestic champions iFlyTek, which invented a robot that passed a Chinese medical licensing exam, and an array of smaller startups.

Money is flowing in. As of August, venture capitalist­s such as Sequoia and San Francisco’s Matrix Partners had invested at least $2.7 billion in such businesses, according to Yiou. Analysts at Bernstein estimated that spending in China’s health tech industry will reach $150 billion by 2020.
