Historical data note (November 2026): The figures below come largely from studies and reports published between 2004 and 2011. They describe historical findings and projections, not current nationwide rates or guaranteed outcomes from telehealth. Results depend on clinical setting, patient population, staffing, and care processes. For updated diabetes estimates, consult the CDC National Diabetes Statistics Report (updated September 16, 2026). For current Medicare telehealth rules, consult HHS Medicare payment policies.

Historical telehealth facts and reported findings:

In a 2011 single-center study, hospital mortality was 13.6% before and 11.8% during a tele-ICU intervention that also redesigned critical-care processes. Average hospital length of stay was 13.3 days before and 9.8 days during the intervention. This observational finding does not establish that remote monitoring alone caused the differences.
