I have a file that has admission and release dates since Jan 1, 2011. I then created monthly dummy variables whether or not the patient was committed (see code below)
I merged this file with mortality data and now I want to create several variables examining how soon after release the patient dies.
Death data is for 2013 and 2014. Month of death in the death file is month_death and year of death is year_death. So since we do not have the actual date, we want to create variables looking at: death on same month of release, at 2 months after release, at 3 months after release, at 6 months after release, at 12 months after release, at 15 months, at 18 months, at 24 months, at 36 months, and at 48 months.
here is my code with the admission/release and monthly counts for being in hospital
