Understanding HAI Rate
How we calculate. Simple HAI % = infection events ÷ discharges × 100 (not NHSN device-day rates). The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical HAI Rate case uses hai events 8 and discharges 2000. Enter the same figures below to reproduce the worked path.
What is HAI Rate?
An educational crude percentage. Official NHSN/CDC measures often use device-days or standardized infection ratios—use those for reporting.
- Not a device-day SIR
- Same discharge window
- Define HAI inclusions
The Formula
Worked Example
Common Use Cases
- Teaching: crude infection math
- Internal screens: event volume
- IP literacy: % vs per 1,000 days
Pro Tips
- Use NHSN specs for official reporting
- Don’t compare crude rates across unlike hospitals
- Pair with hand hygiene process metrics
Limitations: HAI Rate results are Educational operations/planning aids only—not medical, clinical, billing, or regulatory advice. Confirm definitions with your facility policies and clinicians.
FAQ
Is this CLABSI/CAUTI?
No. Those typically use device-days and NHSN rules. This tool is a simple discharges-based percentage.
What if discharges are 0?
HAI rate is undefined—enter positive discharges.
