In the following line of code, the difference is calculated between the offsets difference and 24*3600 which seems to be a comparison to 24 hours.
ABX_BC_pid_offset.loc[(ABX_BC_pid_offset['drugorderoffset'] < ABX_BC_pid_offset['culturetakenoffset']) & (ABX_BC_pid_offset['culturetakenoffset'] - ABX_BC_pid_offset['drugorderoffset'] <= 24 * 3600), 'tSuspicion'] = pd.DataFrame([ABX_BC_pid_offset['culturetakenoffset'], ABX_BC_pid_offset['drugorderoffset']]).min()
From what I understood, the data is from the eicu database. And according to its documentation, the time is calculated in minutes. so it should be 24*60.
If not could you please clarify?
