I get like heart surgery would be low but what effects the percentage? if a theoretical perfect surgen was doing it would the odds be 100% or would it still depend on other factors?
In: Biology
There’s some good responses here, but one other factor would be data on prior outcomes from similar surgery. So, if a surgeon had carried out 1,000 procedures of a specific kind and of all those cases 500 patients survived, they could say that the chance of survival is likely to be 50%. Obviously that would be adjusted by the surgeon for individual cases taking into account the factors mentioned above in the previous comments.
