Insights
Cardiovascular risk management should prioritize absolute risk assessment over relative risk. This approach helps clinicians and patients weigh treatment benefits against hazards for personalized care decisions.
Area of Science:
- Cardiology
- Primary Care Medicine
- Health Decision Science
Background:
- Current cardiovascular risk management trends favor multifactorial and absolute risk assessment over single factors and relative risks.
- Establishing appropriate treatment thresholds requires balancing the benefits and hazards of intervention versus non-intervention.
- Accurate patient absolute risk is crucial for informed treatment decisions in primary care.
Purpose of the Study:
- To review methods for aiding clinical decision-making in primary care for cardiovascular disease.
- To emphasize the importance of considering absolute risk when initiating treatment programs.
- To explore how to present treatment outcomes (benefits, hazards, costs) for various absolute risk levels.
Main Methods:
- Review of existing measures and guidelines for cardiovascular risk assessment and treatment decisions.
- Focus on presenting treatment outcomes in relation to a patient's absolute risk.
- Utilizing cardiovascular disease as a case study for decision-making tools.
Main Results:
- The study highlights the need for accessible presentations of treatment benefits, hazards, and costs across a spectrum of absolute risks.
- Decision-making tools should facilitate the comparison of treatment pros and cons for individual patients.
- Practice guidelines should incorporate these measures to support shared decision-making.
Conclusions:
- Personalized cardiovascular risk management necessitates a shift towards absolute risk evaluation.
- Accessible data on treatment outcomes empowers patients and clinicians in shared decision-making.
- Integrating benefit-hazard-cost analyses into guidelines can optimize primary care for cardiovascular disease prevention.
Abstract:
There is growing consensus that treatment of cardiovascular risks should be based on multiple rather than single factors and on absolute rather than relative risks. Thresholds for treatment should reflect the level of absolute risk at which the benefits and hazards of treating outweigh the benefits and hazards of not treating. Once a decision has been made to initiate a treatment programme, clinicians need to know the patient's absolute risk. At this level of risk do the benefits of treatment outweigh the hazards? Given this information, which treatment option does the patient prefer? Using cardiovascular disease as an example, I review some measures that assist decision making in primary care. Practice guidelines should routinely include accessible presentation of treatment outcomes on benefit, hazard, and costs for a range of absolute risks. These measures enable patients and their doctors to weigh the pros and cons of treatment in their particular circumstances.
