Cardiac Rehabilitation Completion Index (CRCI) Calculator
Session attendance assessment
Enter the number of prescribed sessions and the number attended to calculate the attendance percentage.
About the completion index
This calculator expresses attendance as the percentage of prescribed cardiac rehabilitation sessions that a patient attended. It can be used to describe participation and support a discussion about barriers to attendance.
| Measure | Calculation |
|---|---|
| Attendance percentage | (Sessions attended ÷ Sessions prescribed) × 100 |
| Sessions missed | Sessions prescribed − Sessions attended |
Thresholds retained from the original tool
The original page labels attendance of at least 80% as high, 50% to less than 80% as moderate, and below 50% as low. These bands are presented as operational categories from the original implementation, not as a universally established CRCI classification or a stand-alone prognostic rule.
Clinical context and limitations
- Attendance percentage does not measure the quality, intensity, or completeness of all rehabilitation components.
- Definitions of adherence and program completion vary across studies and services.
- Consider documenting the reasons for missed sessions and whether the prescribed program changed.
- Do not use this percentage alone to infer clinical benefit or determine treatment decisions.
