Hi,
to keep all persons how where discharged more than once try:
sort Id
by Id: gen times_discharged = _N
drop if times_discharged > 1
Assuming you set your data as a panel (commands -xtset- or -tsset- will to it)
you could try to calculate the elapsed time by using the time-series operator
for the first difference:
by Id: gen elapsed_time = D.discharge_date
Best
Oliver
