Background

There have been no reports examining whether Registered Instructors of Cardiac Rehabilitation (Registered Instructors of Cardiac Rehabilitation) contribute to inpatient cardiac rehabilitation (cardiac rehabilitation) participation.

Methods

Using data from the Japanese Registry of All Cardiac and Vascular Diseases and the Diagnosis Procedure Combination (JROAD-DPC) database, we calculated the inpatient cardiac rehabilitation participation rate for each prefecture from 2014 to 2023.

Results

more rehab instructors per area, higher inpatient participation, though weak

More results

The number of Registered Instructors of Cardiac Rehabilitation, cardiologists, general hospital physicians, general hospital nurses, and physical therapists per 100,000 population were also calculated for each prefecture.

More results

The median cardiac rehabilitation participation rate increased from 31.2% to 57.3%, and the total number of Registered Instructors of Cardiac Rehabilitation increased from 3,399 to 7,367 during the study period.

Conclusion

Regions with a greater number of Registered Instructors of Cardiac Rehabilitation consistently demonstrated higher levels of cardiac rehabilitation implementation; however, increases in the number of Registered Instructors of Cardiac Rehabilitation were not directly correlated with longitudinal growth in cardiac rehabilitation utilization.
