Compare diagnosis btw hospital visits

Laugeoe — Mon, 03 Oct 2016 07:36:45 GMT

Dear all.

I hope one of you can help me.

I have an observation for every diagnosis given to a patient.

I have a variable called removal (if the patient has been removed to another hospital on the same day the patient has been discharge from the first hospital).

I would like to find out if the diagnosis given at the first hospital is the same as the diagnosis given at the second hospital.

Example of my dataset

ID Diag Admission Discharge Removal

1 DI451 Date Date 0/1

1 ... .... .... ....

1 ...

2 ...

Can anybody please give an advise?

Best regards

Laugeoe

You need to post sample data and what you'd like to see as the output.

Dear Reeza.
I would like a new variable 0/1 that states if the diagnosis was the same at the two hospitals (1) or if there were a discrepancy..

Ok, somehow join the record to the previous record (SQL Join) or sort your data and use LAG to retrieve the diagnosis code.

If the diagnosis is different set it to 0, otherwise set it to 1.

Your data is missing hospitaID: the hospital where the diagnosis was given. That would make the data much easier to interpret.
