Hospital mortality ratios are a useful if imperfect measure of performance. As you can see in the diagram above, all of the Scottish hospitals cluster around the national baseline and within the safe limits, suggesting a high level of performance including safety for patients with the Western General actually doing a wee bit better than expected.
In NHS England, 8 hospitals have mortality rates above the control limit [bad] while 13 have rates below the limit.
This suggests, I think (statistician alert!), evidence of a more unequal society.
