Understanding Diagnostic Tests for Better Healthcare
Background
Medical students need to learn how to read diagnostic tests well to make smart medical decisions in the future. Natural frequencies help understand test results, but they might not always work well for tests done one after another. This study looks at whether using odds and likelihood ratios can be a good alternative for these cases.
Study Methods
In our study, we included 167 medical students and 162 psychology students. We wanted to see how well they could calculate the positive predictive values (PPV) for a single test and for two tests done in sequence. We also checked how easy the information was to understand.
Results
The results showed that:
- Students were more accurate in calculating PPV when using natural frequencies (36.2%) compared to odds/LR (21.6%).
- However, they were better at calculating sPPV with odds/LR (10.6%) than with natural frequencies (4.9%).
- Students felt they understood information better when it was presented as natural frequencies rather than odds/LR.
Conclusion
Learning about odds/LR alongside natural frequencies may help medical students grasp PPV better, leading to improved diagnostic decisions.
