Insights
Cardiac Phase III (Ph-III) rehabilitation may reduce mortality risk but increase re-events like stent implantations. Further research is needed to confirm effectiveness due to study design limitations.
Area of Science:
- Cardiology
- Public Health
- Rehabilitation Medicine
Background:
- Retrospective cohort study evaluating the cardiac Phase III (Ph-III) rehabilitation program.
- Analysis of effectiveness and sustainability of outpatient cardiac rehabilitation provided by the Centre for Outpatient Rehabilitation (ZAR).
Purpose of the Study:
- To assess the impact of Ph-III cardiac rehabilitation on patient outcomes.
- To determine the effectiveness and sustainability of the ZAR's Ph-III program.
Main Methods:
- Analysis of routine data from 451 patients in the intervention group (IG) receiving Ph-III and 781 patients in the control group (KG) not receiving Ph-III.
- Median observation period of 2.73 years.
Main Results:
- A trend towards 30% less mortality in the IG compared to the KG (relative risk [rr] = 0.70; p = 0.108).
- Increased re-events, primarily stent implantations, observed in the IG (rr = 1.34; p = 0.095).
- Significant differences in baseline characteristics between the IG and KG.
Conclusions:
- Lower mortality risk in the IG may be attributed to close care, healthier behavior, or selection bias in the KG.
- Causality of potential positive effects cannot be confirmed due to the study's retrospective design.
- Further investigation is required to validate the program's effectiveness.
Background:
This retrospective cohort study analyses effectiveness and sustainability of the current cardiac Phase III (Ph-III) rehabilitation program, provided by the Centre for Outpatient Rehabilitation (ZAR).
Methods:
We analysed routine data of 451 intervention group patients (IG, with Ph-III) and 781 control group patients (KG, without Ph-III).
Results:
In a median observation period of 2.73 years we found 30% less cases of death in the IG based on the mortality risk observed in the KG (rr = 0.70; p = 0.108). However, we registered more re-events, mainly stent implantations in the IG (rr = 1.34; p = 0.095). Groups differed in some baseline characteristics.
Conclusions:
The lower mortality risk by trend might be explained by the close-meshed care, the IG patients' more health conscious behaviour or a selection bias of the KG (e.g. more severe underlying disease). The causality of potential positive effects cannot be confirmed by this study because of the study design.
