share wearable – A Yale School of Medicine survey tracking wearable use across 2020, 2022, and 2024 found that more people are wearing these devices—yet far fewer are actually sharing the health data they generate with clinicians.
For years, wearables have been sold as more than gadgets. They’re positioned as quiet health companions—collecting sleep, heart, and activity data—then handing it to clinicians who can use it to make sense of what’s happening in a person’s life.
But the numbers coming out of a Yale School of Medicine study don’t match the promise.
Across three survey cycles—2020, 2022, and 2024—wearable use climbed steadily, while willingness to share tracked health data with clinicians slipped. Actual sharing, meanwhile, stayed stubbornly low throughout the entire stretch.
The study pulled in 17,395 people, asking about wearable use, willingness to share data, and whether they actually shared health information with doctors. It found wearable use rose from 30.2% in 2020 to 41.1% in 2024. About half of the participants reported daily use of their wearable.
The authors pointed to a tension built into the whole idea: “there are opposing trends in device adoption and the level of engagement required for wearable data to meaningfully inform health care.”
What people said they’d do looked encouraging at first. Across the three periods. the share of adults who said they were willing to share their tracked data with clinicians stayed relatively high. though it declined over time. In 2020, 81.3% said they were willing. In 2022, that figure fell to 78.7%. By 2024, it dropped again to 73.4%.
That’s not the part that most sharply contradicts the hype. The real gap is between willingness and action.
According to the study, the proportion of participants who reported actually sharing their device-generated data with doctors was below 20% in every period. In 2020, only 14.2% said they shared that information in the past 12 months. The numbers edged upward to 19% in 2022 and 19.2% in 2024.
The study also zeroed in on digital literacy. Higher digital literacy was linked to increased odds of willingness to share tracked data with clinicians, the report states. But digital skills didn’t automatically lead to real-world sharing of wearable data—people who seemed more prepared to talk about data still weren’t. in large numbers. handing it over.
The discrepancy leaves a simple question hanging over the trend line: why does a device adoption boom and a broadly positive attitude toward sharing still fail to translate into routine clinician data sharing?

So basically people wear these watches but don’t tell their doctors? Seems like a scam on both sides.
I don’t share anything from my Fitbit because last time my info got “leaked” or whatever. Doctors don’t even know what to do with the data anyway.
Wait, I thought the whole point was it sends the data automatically? Like my step count goes somewhere, so I guess I’m technically sharing? Idk it says sharing is below 20% but I assumed that meant like connected apps, not actually talking to a clinician.
This sounds like privacy fear is the reason. But also clinicians probably don’t want more patients with “sleep scores” and “heart rate graphs.” I had one nurse tell me to stop wearing my smartwatch during appointments so yeah.
