Chatzimichail T, Hatjimihail AT. Relation: A Software Tool for Exploring the Relation between Diagnostic Accuracy and Measurement Uncertainty. Ver. 1.0.4.4. Hellenic Complex Systems Laboratory; 2024.
Software Synopsis
This is an exploratory software tool for the relation between diagnostic accuracy measures and measurement uncertainty, as diagnostic accuracy is fundamental to clinical decision making, while measurement uncertainty is critical to quality and risk management in laboratory medicine. It provides five modules with six submodules for calculating, optimizing, plotting, and comparing various diagnostic accuracy measures and the corresponding risk of diagnostic or screening tests measuring a normally distributed measurand, applied at a single point in time in non-diseased and diseased populations. This is done for differing prevalence of the disease, mean and standard deviation of the measurand, diagnostic threshold, standard measurement uncertainty of the tests, and expected loss.
Comment
The Task Group: Analytical Performance Specifications based on Outcomes of the European Federation of Clinical Chemistry and Laboratory Medicine has proposed the program Relation as a tool 'that could help us inform our clinicians, guideline developers and the IVD industry about the impact of analytical performance on test accuracy and clinical decisions' (Horvath AR, Bell KJL, Ceriotti F, Jones GRD, Loh TP, Lord S, Sandberg S, et al. "Outcome-based Analytical Performance Specifications: Current Status and Future Challenges." Clinical Chemistry and Laboratory Medicine. 2024;62(8):1485-1493. DOI: 10.1515/cclm-2024-0125).
