In 2023, 43% of U.S. adults reported using at least one digital health tool, yet unmet need is still stark, with 29% of adults with depression or anxiety saying they did not receive needed mental health care in the past 12 months. When you compare mental health conditions, acute risk, and the size of care delivery and software markets, the gaps become much easier to see, and much harder to ignore.

- A 2021 systematic review reported that telepsychiatry was associated with comparable clinical outcomes to in-person care (no significant difference in many studies), quantifying parity
- U.S. average annual cost per inpatient day for mental health-related care varies by facility but was reported at ~$1,000 to $2,500 in a 2020 AHRQ cost report range, useful for cost benchmarking
- A 2020 review estimated that task-shifting and collaborative care models can reduce overall costs by about 10% to 20% while improving outcomes, giving a quantified cost window
- A systematic review reported that telehealth reduced total healthcare costs by an average of about 20% in included studies, quantifying potential savings
