Dynamic Multi-Stage Cardiovascular Screening Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting cardiovascular disease in asymptomatic individuals are inefficient and costly, as they focus on risk factor modification rather than early detection of vascular and cardiac abnormalities, leading to inadequate prevention and increased healthcare costs.
Innovation Solution
A dynamic multi-stage test administration system that reduces the number of tests required for screening, utilizing a series of non-invasive assessments to identify early markers for cardiovascular disease, allowing for targeted prevention and therapy in high-risk individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all 10 tests are administered to every individual, then detection precision is improved, but productivity decreases and device complexity increases
Solution Approach 1:
The testing protocol is segmented into multiple stages: an initial brief screening with 4 tests, followed by a more comprehensive 10-test evaluation only for those who screen positive. This segmentation allows the system to maintain high detection precision for the full evaluation while improving overall productivity by limiting the number of people who undergo the time-consuming complete assessment.
Solution Approach 2:
The system applies partial action by administering only 4 tests initially rather than all 10 tests to every individual. This partial evaluation is sufficient to identify high-risk individuals who then receive the complete 10-test assessment, thereby maintaining detection precision while significantly improving screening productivity.
2Measurement precision
If all 10 tests are administered to every individual, then detection precision is improved, but loss of time increases
Solution Approach 1:
The evaluation is divided into two temporal stages: a rapid initial screening phase using 4 tests that takes minimal time, and a subsequent comprehensive evaluation phase using all 10 tests that is reserved only for those who screen positive. This segmentation reduces overall time loss while preserving detection precision for those who need it.
Solution Approach 2:
A preliminary brief screening with 4 tests is performed before the complete 10-test evaluation. This preliminary action quickly identifies individuals who are unlikely to have abnormalities, allowing the system to avoid wasting time administering all 10 tests to low-risk individuals while maintaining precision for those at risk.
3Measurement precision
If all 10 tests are administered to every individual, then detection precision is improved, but device complexity increases
Solution Approach 1:
The testing system is segmented into two distinct operational modes: a simplified 4-test screening mode and a comprehensive 10-test evaluation mode. This segmentation reduces device complexity by allowing the system to operate in the simpler screening mode for most individuals while retaining the capability for full evaluation when needed, thus maintaining detection precision without requiring the complex full evaluation to be constantly deployed.
Solution Approach 2:
The system applies partial action by implementing a reduced 4-test protocol that captures the essential screening functionality without requiring all 10 tests to be administered to every individual. This partial implementation reduces device complexity and operational burden while maintaining adequate detection precision through the dynamic escalation to full evaluation for high-risk cases.

AI summary
A system and method for dynamic multi-stage test administration for detection of cardiovascular disease may include performing a first set of tests in a first stage of testing on a patient. Physiological results for each of the tests in the first stage may then be received. Then, based on the physiological results, dynamically determining a set of tests to perform on the subject in a second stage of testing. Additionally, the dynamically determined set of tests in the second stage of testing may be performed on the subject.
