The Israeli project is an "exceptionally thoughtful idea," said Jeremy Levin, chief executive officer of New York-based Ovid Therapeutics Inc. and former head of Teva Pharmaceutical Ltd., the world's largest generic drugmaker. "It's really helpful, and if they tie it to genetic data its value will be tremendous."
National digital-health projects already exist in the U.K. and Scandinavia, Iceland is trying to sequence its citizens' genes, and Stanford University in California is running a digital health-tracking program. The Israeli plan has the potential to go further, Levin said.
"It needs to have clinical, epidemiological, biochemical and genetic data," he said. "Because Israel has one of the best medical systems in the world, it will help define patient subgroups and attract investment from companies seeking to do clinical trials on a well-defined population."
Coming amid intense public debate on data security in the wake of Facebook's Cambridge Analytica scandal, the announcement has raised concerns about how participants' health data would be protected.
Hackers are eager to steal patient data, which contain personal details that might help them break into bank accounts or embarrassing information that could be used for extortion, according to Daniel Brodie, co-founder of Cynerio, an Israeli startup specializing in cyber-security for health-care providers.
Israeli regulation of patient data is "very behind" the U.S. and Europe, Brodie said, echoing what Groner called a "Wild West" situation where data gathered by health maintenance organizations isn't currently monitored by a governmental body.
"I get queasy when I see the government rushing ahead when you're not sure if the government can protect the data like it should," said Brodie, whose firm is working with eight Israeli hospitals and HMOs and is helping the government craft cyber regulation in that field. "Even if the people are volunteering, it's not a question about if it will be hacked, but when and how prepared the government is for that."
Groner said officials are working on regulations limiting how the data could be used and what measures must be in place to protect it.
A former member of Israel's national baseball team, Groner likened the digital health project to the explosion of data analysis that revolutionised the sport, as immortalised in Michael Lewis' "Moneyball."
"You'll be able to identify insights that mankind previously has been unable to identify," he said.
