Is there a method or solution to compare the date in one record to the date in another record and provide a result based on the comparison?
e.g., in below matrix when record 2 admit_date (1/3/13) is between record1 disch_date+1 and disch_date+30 then Y else N end
I have strung out the data and was able to easily make the comparison.
admit_date1 disch_date1 admit_date2 disch_date2 12/20/2012 12/22/2012 1/3/2013 1/6/2013
Comparing disch_date1 to admit_date2 such that admit date was within 30 days of discharge is a y
However, the challenge is to format the data in a friendly format for analysis. Stringing out the data based on patient rather than presenting data by encounter record makes the analysis very cumbersome as there may be up to eight discharges per patient within the requested date range. There are 15000+ patients in the cohort.
Ideally for analysis the data set would look like this:
record pt admit_date disch_date y/n 1 A 12/20/2012 12/22/2012 n 2 A 1/3/2013 1/6/2013 y 3 A 3/1/2013 3/3/2013 n 4 A 4/5/2013 4/6/2013 n 5 B 2/28/2013 3/4/2013 n 6 B 3/27/2013 4/4/2013 y 7 B 4/5/2013 4/8/2013 y
