Hi all,
I am trying to calculate the time from the last tube feed (tube_stopped) to the time of surgery. Each patient has multiple tube stop times and also multiple surgeries (date_procedure). I want to create a new variable that calculates this called "Time from last tube feed to procedure" in hours....
Data have:
ID tube_stopped date_procedure
7 12Jul17:02:00:00 13JUL17:13:00:00
7 01AUG17:15:00:00 01AUG17:22:00:00
7 20JUL17:07:35:00 20JUL17:22:00:00
1 29JUL16:01:00:00 29JUL16:23:00:00
1 12AUG16:16:00:00 12AUG16:22:00:00
Data want:
ID tube_stopped date_procedure time from last tube feed to procedure
7 01AUG17:15:00:00 01AUG17:22:00:00 2.4
1 12AUG16:16:00:00 12AUG16:22:00:00 5.7
