Why is the Bayesian method not employed for diagnosis in practice

In this attached paper, I discuss that the prescribed Bayesian method is not employed for diagnosis in practice because probability of a diseases is considered evidence for it in a given patient in this method, which is incorrect as a probability is a frequency in a population. This leads to all sorts of errors in practice which I discuss.
The correct method of diagnosis, which is employed in practice, consists of hypothesis generation and verification in which evidence is assessed by a likelihood ratio which locates it in the given patient of interest.
Please review and comment on this paper.

Thanks
