Figure 2b is a line graph depicting the temporal change in the population-based rate of post-mortem examinations of suspected prion disease case deaths, by year (1993-2015) and state and territory for ACT, NT, SA and TAS. In these regions with smaller population sizes, there is an overall temporal increase in the post-mortem rate although there remains significant variability. The exception is SA, where the rate has been variable with no clear trend over the time-frame. The overall positive trends observed are attributed to increased awareness of prion disease in the healthcare setting.
