Insights
Higher numbers of Registered Instructors of Cardiac Rehabilitation (RICRs) correlate with increased inpatient cardiac rehabilitation (CR) participation rates. However, the growth in RICR numbers did not directly drive the overall increase in CR utilization.
Area of Science:
- Cardiology
- Public Health
- Healthcare Management
Background:
- Limited research exists on the impact of Registered Instructors of Cardiac Rehabilitation (RICRs) on inpatient cardiac rehabilitation (CR) participation.
- Understanding factors influencing CR participation is crucial for improving cardiovascular patient outcomes.
Purpose of the Study:
- To investigate the association between the number of RICRs and inpatient CR participation rates.
- To examine the relationship between RICR density and CR implementation across Japanese prefectures.
Main Methods:
- Utilized data from the Japanese Registry of All Cardiac and Vascular Diseases and the JROAD-DPC database (2014-2023).
- Calculated prefecture-level CR participation rates and the density of RICRs and other healthcare professionals per 100,000 population.
- Conducted correlation analyses to assess the relationship between RICR numbers and CR participation rates.
Main Results:
- The median inpatient CR participation rate increased from 31.2% to 57.3% between 2014 and 2023.
- The total number of RICRs in Japan rose from 3,399 to 7,367 during the study period.
- A positive correlation was observed between the number of RICRs and CR participation rates in 2023 (r=0.31, P=0.03).
Conclusions:
- Prefectures with a higher concentration of RICRs showed consistently higher CR implementation.
- Increases in RICR numbers were not directly associated with the longitudinal growth in CR utilization over the study period.
Background:
There have been no reports examining whether Registered Instructors of Cardiac Rehabilitation (RICRs) contribute to inpatient cardiac rehabilitation (CR) participation.
Methods And Results:
Using data from the Japanese Registry of All Cardiac and Vascular Diseases and the Diagnosis Procedure Combination (JROAD-DPC) database, we calculated the inpatient CR participation rate for each prefecture from 2014 to 2023. The number of RICRs, cardiologists, general hospital physicians, general hospital nurses, and physical therapists per 100,000 population were also calculated for each prefecture. The median CR participation rate increased from 31.2% to 57.3%, and the total number of RICRs increased from 3,399 to 7,367 during the study period. In prefecture-level correlation analyses for 2023, the number of RICRs was positively associated with the CR participation rate (r=0.31; 95% confidence interval 0.02, 0.55; P=0.03). In contrast, the increase in the number of RICRs was not significantly associated with the growth of CR participation during the study period.
Conclusions:
Regions with a greater number of RICRs consistently demonstrated higher levels of CR implementation; however, increases in the number of RICRs were not directly correlated with longitudinal growth in CR utilization.
