Hi all

I was hoping someone had had experience of estimating relative survival from stpm2. I am trying to take account of case mix by hospital and I can do this sort of ok, but what I need to do is extract the % relative survival as a result of correcting for certain factors.

My current unadjusted model is this:

hosp1, hosp2, hosp3 hosp4 include binary variables that state whether a case belongs to that hospital or not and I have 4 hospitals

stpm2 hosp2 hosp3 hosp4, scale(hazard) df(5) tvc(hosp2 hosp3 hosp4) dftvc(3)
range temptime 0 5 200
predict rs1, survival timevar(temptime) zeros ci

predict rs2, survival timevar(temptime) at(hosp2 1) zeros ci

predict rs3, survival timevar(temptime) at(hosp3 1) zeros ci

predict rs4, survival timevar(temptime) at(hosp4 1) zeros ci

What I would to do is collapse the data to obtain the grouped 1 year survival for each hospital. After I get this working, I can start to add other variables into the model.

This is my first time on here, so apologies for any lack of information.
