Good Morning all,

 

Below is my data. I just wanted to retain extubation timestamp.  For patients who had extubated once I am able to retain their extubation time but there are some patients who extubated more than once during their admission (means they got intubated twice). Below is an example of such patients and I want to retain ext_ts as shown in last column.

 

Thanks in advance.

I am not here to type test data in, so this code is untested:

data want (drop=tmp);
  set have;
  retain tmp;
  if ext_ts ne . then tmp=ext_ts;
  if ext_ts=. then ext_ts=tmp;
run;

Thank you, I realized this that I should have codes in my post after I posted. Thanks again.

RW9, you solved my problem in such a simple way and I was making it so complicated. Today I realize the fact that we should not think too much every time. Thanks again

One thing I would point out is that if the first ts in the group is null it will retain across from previous row.  May not be an issue but if it is then put a by <group> and use that in the if's as well, i.e. if first.<group> then ...
