Abstract:
The Three Period Crossover Phased Diagnostic Screening Test is a test design aimed at evaluating consistency of clinical performance of Clinicians, this process involve repeated measurements of a clinical search for a disease or medical condition of interest. The repeated nature of the test is to enable calculation of performance errors. This process is phased in such a way that previous trials do not influence the outcome or outcomes of subsequent phase or phases. Processes of computing probabilities of various possible sequence of outcomes, positive or negative, for the assessment of clinicians’ consistency were developed and presented. Its functionality was demonstrated with an illustrative example. The beauty of the Three Period Crossover Phased Diagnostic Screening Test is that no matter the order the three Clinicians carry out the phased diagnostic tests the probability of positive outcomes by any chosen clinician or the probability of negative outcomes of any chosen clinician can still be calculated accurately.
