Americans are crazy about fitness trackers, but a recent survey suggeststhey are not doing much about the information they gain from thepopular devices.

The survey of 2,500 people enrolled in health plans by HealthMinefinds that 46 percent of those who have access to digital healthtools say they do not shift their health care decisions as a resultof the data produced by the devices.

Furthermore, while three-quarters of those who use health careapps say they are willing to share their health data with a healthcare provider, only about a third say their device is set up toautomatically share it.

As a result, argues HealthMine, many Americans are not gainingthe full benefit of the technological revolution underway in healthcare.

Those who are in greatest need of health-tracking devices arethe least likely to use them, the survey finds. Only 16 percent ofthose with a heart condition use activity trackers.

Similarly, the country has a long way to go in terms ofengagement with telemedicine. Many patients appear to view digitalhealth records and telehealth solutions as little more than ways tosave money, rather than an opportunity to better shape their healthcare decisions.

For starters, many have never even heard of telemedicine, including 40 percent of those whouse online health apps.

And while 60 percent of those who use digital tools say theyhave an electronic health record, only about a third of that groupreports consulting the EHR to make health care decisions.

Accompanying the increasing popularity of fitness trackers hasbeen a rising skepticism of their usefulness.

A number of studies finding that some of the most populartrackers on the market are often inaccurate and a study late lastyear finding no evidence that trackers motivate people to exercisemore; it in fact found the opposite was true. Fitbit, the manufacturer of one of the mostpopular activity tracking devices, pushed back on the study’sconclusion, pointing out that the data had been collected severalyears before.
