Description

Hello,
I have a question regarding the different values of admission_type in admission table, and how can to find out if an admission is an urgent admission or an elective (planned) one?

The admission type contains the following values:
‘AMBULATORY OBSERVATION’,
‘DIRECT EMER.’,
‘DIRECT OBSERVATION’,
‘ELECTIVE’,
‘EU OBSERVATION’,
‘EW EMER.’,
‘OBSERVATION ADMIT’,
‘SURGICAL SAME DAY ADMISSION’,
‘URGENT’

Thanks,
