Big Tech is carving up turf (and profits) in your healthcare

New York

WHEN Daniel Poston, a second-year medical student in New York, opened the App Store on his iPhone a couple of weeks ago, he was astonished to see an app for a new heart study prominently featured.

Patients often learn about new research studies through in-person conversations with their doctors. But not only did this study, run by Stanford University, use a smartphone to recruit consumers, it was financed by Apple. And it involved using an app on the Apple Watch to try to identify irregular heart rhythms.

Intrigued, Mr Poston, who already owned an Apple Watch, registered for the heart study right away. Then he took to Twitter to encourage others to do likewise - suggesting that it was part of a breakthrough in healthcare.

"It's not inconceivable, by the time I graduate from medical school, that the entire practice of medicine can be revolutionised by technology," he said.

Apple, Google, Microsoft and other tech giants have transformed the way billions of us communicate, shop, socialise and work. Now, as consumers, medical centres and insurers increasingly embrace health-tracking apps, tech companies want a bigger share of the more than US$3 trillion spent annually on healthcare in the US, too. The Apple Heart Study reflects that intensified effort.

The companies are accelerating their efforts to remake healthcare by developing or collaborating on new tools for consumers, patients, doctors, insurers and medical researchers. And they are increasingly investing in health startups.

In the first 11 months of this year, 10 of the largest tech companies in the US were involved in health-care equity deals worth US$2.7 billion, up from just US$277 million for all of 2012, said CB Insights, a research firm that tracks venture capital and startups.

Each tech company is taking its own approach, betting that its core business strengths could ultimately improve people's health - or at least make healthcare more efficient. Apple, for example, has focused on its consumer products, Microsoft on online storage and analytics services, and Alphabet, Google's parent company, on data.

John Prendergass, associate director of health-care investment at Ben Franklin Technology Partners, a non-profit organisation in Philadelphia, said: "The big-picture reason that a lot of these tech companies are getting into healthcare now is because the market is too big, too important and much too personal to their users for them to ignore."

Physicians and researchers caution that it is too soon to tell whether novel continuous-monitoring tools, like apps for watches and smartphones, will help reduce disease and prolong lives - or just send more people to doctors for unnecessary tests.

Dr Eric Topol, a digital-medicine expert who directs the Scripps Translational Science Institute in San Diego, said: "There's no shortage of hype. We're in the early stages of learning these tools: Who do they help? Who do they not help? Who do they provide just angst, anxiety, false positives?"

The tech industry is certainly no stranger to health. IBM, Intel and Microsoft have long provided enterprise services to the health-care industry.

But now they, and other companies, are more visibly focused on creating, or investing in, new kinds of technologies for doctors, patients and consumers.

This year, Amazon was one of the investors in a financing round for Grail, a cancer-detection startup, which raised more than US$900 million; Apple acquired Beddit, a maker of sleep-tracking technology, for an undisclosed amount.

And Alphabet, perhaps the most active American consumer tech giant in health and biotech, acquired Senosis Health, a developer of apps that use smartphone sensors to monitor certain health signals, also for an undisclosed amount.

Alphabet also has a research unit, Verily Life Sciences, dedicated to developing new tools to collect and analyse health data.

This year, it introduced a health-research device, the Verily Study Watch, with sensors that can collect data on heart rate, gait and skin temperature. Now, the watch is to be used in a research study, called Project Baseline and financed by Verily, to follow about 10,000 volunteers.

Apple is taking a different approach - using its popular iPhone and Apple Watch to help consumers better track and manage their health.

"Apple is trying to drag medicine from where it currently takes place - in hospitals and clinics - and move it to the consumer side, to your phone," said Malay Gandhi, an executive in residence at Greylock Partners, a venture capital firm.

In 2015, Apple introduced new software, called Apple ResearchKit, for health researchers. Stanford used it to develop an app to enroll volunteers in a heart study and track their physical activities, sleeping hours and fitness.

Dr Lloyd Minor, dean of the Stanford University School of Medicine, said the app enabled researchers to smoothly enroll more than 54,000 patients - a large number for a study conducted by one medical centre - and collect much more data than they could have otherwise.

"For us, it was an eye-opener," he said.

Microsoft, already a major supplier of software and cloud services to medical centres, is also ramping up its health business.

This year, the company announced an initiative, Healthcare NeXT, to create products for medical providers and patients using artificial intelligence and cloud services like speech recognition.

As part of the effort, Microsoft worked with the University of Pittsburgh Medical Center (UPMC) to develop digital services intended to reduce drudgery for physicians and improve patients' experiences. One project involves a virtual assistant that would take notes on conversations between a doctor and a patient, analyse the conversation and then send a summary to the patient's electronic medical record. The medical centre is also pilot-testing an app that notifies doctors when one of their patients has filled a prescription at a UPMC pharmacy.

"We're really focusing on what people in the health-care world are doing today and how we can make it better," said Peter Lee, Microsoft's corporate vice-president for artificial intelligence and research.

Facebook, too, has been expanding its business and research efforts in the health sector.

Last year, Facebook made it more appealing for pharmaceutical companies to advertise their medicines on the platform by introducing a rolling scroll feature where drugmakers can list their drug's side effects in an ad. Such risk disclosures are required by federal drug marketing rules. NYTIMES
