Medical decision-making often overlooks patient goals beyond quality-adjusted life years (QALYs). This study explores incorporating unique, time-specific patient goals into cost-effectiveness analyses for better healthcare evaluations.
Area of Science:
- Health Economics
- Medical Decision Making
- Patient-Centered Care
Background:
- The quality-adjusted life year (QALY) model primarily addresses ongoing health goals like pain reduction or mobility maintenance.
- Patient preferences sometimes conflict with the QALY model, suggesting the existence of goals not captured by it.
- Goals such as completing significant life events (e.g., project completion, child's graduation) are time-specific and difficult to quantify within the QALY framework.
Purpose of the Study:
- To examine methodologies for integrating extrinsic, time-specific patient goals into medical decision and cost-effectiveness analyses.
- To demonstrate the application of these methods using existing case studies.
Main Methods:
- Review and analysis of existing decision-making frameworks.
- Application of proposed methods to re-evaluate previously published analyses.
- Illustrative examples include management of unruptured intracranial arteriovenous malformations and preventive strategies for BRCA+ women.
Main Results:
- The study proposes and illustrates methods to incorporate extrinsic goals into analyses.
- Revisiting case studies demonstrates how these goals can influence outcomes and decisions.
- This approach offers a more comprehensive understanding of patient preferences in healthcare.
Conclusions:
- Standard models like QALYs may not fully capture all patient goals, particularly time-specific ones.
- Integrating extrinsic goals enhances the accuracy and patient-centeredness of medical decision and cost-effectiveness analyses.
- This expanded approach can lead to more aligned healthcare recommendations and resource allocation.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
