By 2023, 85.0% of Americans say they want more transparency about how AI is used, even as 42.0% of clinicians report workflow improvements after adopting digital tools. This post gathers the other ways to think about “statistics” by pairing adoption and outcomes side by side, from everyday searches for mental health help to the measurable impact remote monitoring can have on readmissions. You will see how usage patterns shift from early trial adoption to near daily behaviors, and why that matters for what the next generation of digital care should be built to do.
