When the goal is to prioritize patients for lung transplantation and when a patient’s clinical status is changing over time. Therefore, we presented an approach that uses time-dependent classification error rates which will be wont to characterize the potential performance of a survival model, while accounting for the time-varying nature of the prediction itself. whereas the performance of a baseline measurement declines over time. Thus, previously reported estimates of the accuracy of FEV1% alone don't capture its true performance during a clinical setting. it's clear that patient information should be updated over time to take care of classification accuracy; however, it's also evident that neither FEV1% alone nor existing multivariate models are adequate to be used in practice.Being able to guage a model’s time-varying accuracy can also help guide clinical practice and policy with regards to the frequency of updating patient information. A comparison of 1-year versus 2-year measurements of FEV1%, for instance, showed minor differences in performance.
