By saying that it won't work do you mean? that the stset command would give me an error?
Because I am doing it and it does set the data.

In my dataset I have admission as well as discharge/death date per observation

In Statas manual the stset takes the form of:
stset failuretime, failure(mortality==1) id(id) enter =(admissiontime)

so why it would not work if my dataset as I showed an example earlier has unique observations that have the admission date as well as the discharge/death date?

No; that won't work. You don't have a single time variable or survival variable. What makes you think that compatible with -stset-?

You need to -reshape- your data.
