Hi Members,

1. Same patient (id) has bills start at the same service center (service id) on March 31th and then end on May 11th, there are multiple costs happen, this considers as one episode. (see sample data below)

First is to describe the logic you use to DEFINE episode. Examples are nice to see how the definitions are applied but the base definition is important. Such as what makes your example 4 two different episodes when example 2 isn't ?

Are your Start_dt and End_DT SAS date variables? If not it's a good idea to make them so.

I would start with something like this:

Proc sort data=<start dataset name>; by id serviceid start_dt;run;

data second;

     set <start dataset name>;

     by id serviceid;

     retain episode 0;

     if first.serviceid then episode=episode+1;

    /* is suspect you want a piece here examining the current start date

    with the previous end date but don't know the rule. maybe something like*/

     if intck('DAY',start_dt, lag(end_dt)) > 10 then episode=episode+1;

    

run;

The order of output woud differ but:

proc tabulate data=second;

     class id serviceid episode;

     var start_dt end_dt amount;

     table id*serviceid*episode,

             start_dt*min=''*f=mmddyy10. end_dt*max=''*f=mmddyy10. amound*sum=''*f=f10.2;

run;

might be start

Hi ballardw,

Thank you for your reply.

The difference between rule 2 and rule 4 is because there is no gap between these two cases for rule 2, the bill ends on 11/3/2010 at the first case, and the start day on second case is 11/4/2010 while there is a gap between two cases for rule 4. The rule of building the episode relys on ID, Service ID, Start_DT, End_DT. Futhermore, Start_DT and End_DT are SAS date variables, I format them when I output this table.

Thanks again.

Assuming that stays tha are consecutive must be fused into the same episode, the solution could be:

data test;
input ID serviceID startD :mmddyy. endD :mmddyy. amount;
format startD endD yymmdd10.;
