Insights
Aspirin-clopidogrel combination therapy is more cost-effective than aspirin alone for ischemic stroke, showing better clinical outcomes at lower costs. This dual therapy offers a favorable alternative for stroke management.
Area of Science:
- Pharmacoeconomics
- Clinical Medicine
- Cardiovascular Research
Background:
- Ischemic stroke management requires evaluating treatment cost-effectiveness.
- Aspirin-clopidogrel combination therapy is an alternative to aspirin monotherapy.
- Coagulation parameters like PT and APTT are key clinical indicators.
Purpose of the Study:
- To assess the cost-effectiveness of aspirin-clopidogrel combination versus aspirin alone in ischemic stroke.
- To evaluate the clinical impact on coagulation parameters (PT, APTT).
- To analyze direct medical costs from a hospital perspective.
Main Methods:
- Observational study comparing inpatient ischemic stroke cases.
- Analysis of direct medical costs and coagulation parameters (PT, APTT).
- Incremental Cost-Effectiveness Ratio (ICER) calculation without discounting.
Main Results:
- Aspirin-clopidogrel combination therapy showed superior cost-effectiveness.
- ICER values indicated dominance: PT (IDR -246,930/second) and APTT (IDR -119,270/second).
- Combination therapy yielded better clinical parameter values at lower costs.
Conclusions:
- Aspirin-clopidogrel combination therapy is a dominant and cost-effective strategy for ischemic stroke.
- The findings suggest potential economic and clinical advantages for routine stroke management.
- Combination therapy presents a favorable alternative for clinical practice.
Abstract:
Understanding the cost-effectiveness of aspirin-clopidogrel combination therapy is crucial in determining its influence on coagulation parameters, specifically prothrombin time (PT) and activated partial thromboplastin time (APTT). The aim of this study was to assess the cost-effectiveness and clinical impact of using the aspirin-clopidogrel combination compared to aspirin alone in managing ischemic stroke. Employing an observational research design, inpatient ischemic stroke cases receiving the aspirin-clopidogrel combination were compared to those treated with aspirin alone. Focusing on the hospital's perspective on costs, the research specifically analyzed medical expenses without discounting costs or effects. The analysis involved comparing the direct medical costs and coagulation parameters between the two treatment groups. Our data revealed that the aspirin-clopidogrel combination demonstrated superior cost-effectiveness over aspirin alone, indicated by the incremental cost-effectiveness ratio (ICER) values for PT (IDR -246,930/second) and APTT (IDR -119,270/second). This indicated that the combination therapy was associated with lower costs while yielding better clinical parameter values. The ICER analysis placed the aspirin-clopidogrel combination in the southeast quadrant, marking its dominance over aspirin monotherapy by demonstrating higher effectiveness at lower costs. These results suggest that combination therapy might be a favorable alternative for managing ischemic stroke, presenting a viable option for consideration in clinical practice. The findings underscore the potential economic and clinical advantages of employing the aspirin-clopidogrel combination in routine stroke management protocols.
