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,

I got a same question. Could you share the review after getting answer?

I am a Swiss physician somewhat familiar with the US health care system. That's how I would address this:

Mapping:
-- Emergency: ‘AMBULATORY OBSERVATION’, ‘DIRECT EMER.’, ‘URGENT’, ‘EW EMER.’, ‘DIRECT OBSERVATION’, ‘EU OBSERVATION’, ‘OBSERVATION ADMIT’
-- Elective: ‘ELECTIVE’, ‘SURGICAL SAME DAY ADMISSION’

I agree with @mirkompcr, this is how I would group them as well.

The classification of admissions types is also unfamiliar to me. I have decided to adopt the mapping scheme provided by mirkompcr in my paper! Thanks very much!@mirkompcr
