Hi There,
Does anyone has developed a decision tree on a hospital discharge delays. The goal is to discharge a patient within two hours of discharge order written date/time. I need to develop a decision tree on factor affecting a prolonged discharge delay ( > 2h vs <2 hours).
Is there anyone who can navigate me thru their experience/result that could be shared?
Really appreciate your valuable comments
Thanks

I don’t know what all those variables mean, but I suspect you do not have the data needed. If you want to use the data you have you can use a decision tree and treat outcome as either a binary outcome or as a categorical variable if you bin the delay into groups.
Otherwise, you can also treat it as a continuous variable to look at length of delays or even a two stage model - probability of a delay, then if there is a delay, how long can it be.
Note that that your data should have a portion that has delays and no delays to ensure you’re getting actionable results. You may want to do a case control matching to ensure you a good ratio of events to non-events.

Hi Reeza
Yes I do have data with following variables.
Basically we are trying to find what are the factors influencing discharge
delays and which node of DT has most significance impact on discharge
delays.
Will you please guide if the DT is appropriate method to figure out where
the bottle necks are for the discharge delays?

My outcome variable is the time between physician's discharge Order to Patient discharge time. The goal is have it less than 2 hours. So I will create a new binary variable where if the time between physician's discharge Order time to Patient discharge time is less than 2 hours vs more than 2 hours.
My independent variable would be nursing unit, age , DRG, insurance etc.
I have some understanding but not as expert as you guys are. I am looking for some sample, articles on how it might looks like and showcase this to my director so that they might buy me a sas visual statistics and miner.
Please share if you have any thing related to these.
Thanks
