Hello, what is your location?
Can I ask the reason for the question?
There are different tools available and much depends on your location (USA or UK for example)
Also, did you have two specific hospitals in mind?
In the US the Medicare services has put together a great site which has sections on what care measures are and allows you to compare hospitals. It also has survey results for patient views.
So if you are thinking of what is important, then overall infection rate, mortality or surgical success rate are all essential however you should not forget to include patient factors such as food, and overall satisfaction.
This is the link to the site: here
