Robust Timing for Medical Screening

Medical tests are only valuable to the extent that they change what clinicians do next, and that value depends critically on how fast risk accumulates between “wait” and “act.” Recent research by Prof. Thomas A. Weber, presented at IEEE SCSE 2026, analyzes medical screening decisions when prevalence dynamics are misspecified. The work proposes a simple, robust rule with a relative performance guarantee, illustrated on post-exposure tuberculosis infection screening where timing choices span weeks to years and speed ambiguity is clinically consequential.
