The introduction of the pulse-reading Apple Watch along with HealthKit
software designed to log activity and health data form something of a
beachhead into the $2.7 trillion U.S. health sector, a vast domain where
tech companies large and small have been trying to improve care and reduce
cost. And because it’s Apple (AAPL), a move into health care is worth
watching closely.
The smartwatch described in Apple Chief Executive Tim Cook’s presentation
on Tuesday appears to be a more sophisticated tracking gadget than FitBits
or GPS-equipped running watches. The Apple Watch can certainly capture more
precise data. Combined with HealthKit’s power to connect fitness, nutrition
, and medical data, it will likely have hard-core adherents of the
quantified self movement jumping for joy (and measuring how high). More
casual users may find it interesting to see, for example, whether their
RunKeeper workouts affect how well they snooze as measured by Sleep Cycle.
HealthKit will make that kind of analysis simpler, enticing more iPhone
users into the world of obsessively measuring their personal performance.
The more intriguing potential of Apple’s new health-care gadgetry is
whether it can change behavior, a notoriously tricky challenge for public-
health wonks. “Apple Watch gives us the ability to motivate people to be
more active and more healthy,” Cook promised. The device will be able to
prompt users to stand up after sitting for too long and effortlessly track
progress toward workout goals.

Chronic disease accounts for three-fourths of U.S. health-care costs, and it
’s largely driven by smoking, diet, and physical activity, all behaviors
people can modify. The question is whether an Apple Watch or any gadget can
actually goad people into moving—or simply provide a way for those already
motivated to work out to measure it more precisely. We don’t know yet. Most
Americans are overweight or obese, and it’s going to take much more than a
buzzing wristwatch to dent our weight problems.
But at the margin, for some people, the Apple Watch might help. If not, at
least you can still send goofy emoji to your friends.
Apple’s nascent health-care strategy may change the way people who are
actively managing chronic diseases such as diabetes or depression experience
care. Programs exist to remind people to take medications or help them
track their moods, and HealthKit should allow those apps to work more
smoothly together and transmit data to doctors’ records—confirming that
patients took a dose of medicine, for example.

It will also likely accelerate the trend of consultations by phone or
computer. Apps and devices such as blood-glucose meters or blood-pressure
cuffs that connect to phones and send data to doctors will expand that trend
. HealthKit will plug into electronic health records from Epic and other
providers, enabling smoother communication between doctors and patients.
Apple’s technology could eventually have big consequences for public health
and the field known as population health management. That’s the goal of
lots of hospitals and health plans: to monitor the health of large groups of
people and intervene before illnesses become costly, acute hospital stays.
It may also open new frontiers for medical researchers, who have already
used smartphones in innovative ways. One study used phones to track the
activity of drug users for insights into what makes addicts relapse.
Think of the way Google’s (GOOG) traffic maps detect a backup by examining
anonymous location data from lots of Android users stuck in a jam. What
might Apple be able to detect by aggregating the daily movements, heart
rates, and other health data of potentially millions of Apple Watch users?
Could it spot the spread of flu or other infections by detecting regional
drops in activity? Such scenarios raise questions about privacy and security
, of course, and it’s hard to know what role, if any, the Watch might play.

But it’s clear that HealthKit and the Apple Watch are the start of a foray
into a giant market that affects everyone personally and is at the core of
America’s fiscal problems. And there’s always one more thing. As sharp-
eyed Apple watchers know, the company already has a patent on earbuds that
can measure your temperature and heart rate.
