How can hospitals measure ROI from an EHR system?
Baseline the numbers 90 days before go-live, or you'll have nothing to compare against.
Then track a handful of things that actually move:
- Denial rate and days in AR (this is where most of the money is)
- Documentation minutes per encounter, pulled from audit logs
- Duplicate tests ordered within 30 days
- Time to produce audit evidence when someone asks
Two honest caveats. Ignore the first 90 days after go-live, throughput always dips. And full ROI usually shows up at 24-36 months, not year one.
The trap is attributing everything to the EHR when you also changed staffing and workflow in the same window.
(I work in healthcare compliance software, so the audit angle is my bias.)
