Count with multiple criteria

Whitlea — Fri, 02 Aug 2024 00:18:17 GMT

I want to know how many clients in each clinic stayed at a different clinic and the cost of the stay at the different clinic. I am not considering order of the stays. I do not want to count a client if they have a different stay in the same clinic (see client L).

Thank you for your help!

data have;
input
client$	Span_Begin :DATE9.	Span_End :DATE9. clinic$ stay cost;
 

format Span_Begin MMDDYY10. Span_End MMDDYY10. ;

Thank you for providing working code to create dataset HAVE.

You "want to know how many clients in each clinic stayed at a different clinic and the cost of the stay at the different clinic."

Your desired result for clinic 3 shows a COUNT of 1 and a COST of 9,588.

Now the only client for clinic 3 that has stays at other clinics client L, which explains why you have a COUNT of 1. But, with the following data for L

Client	Span_Begin	Span_End	Clinic	Stay	Cost
L	07/01/2022	07/15/2022	1	3	9,588
L	07/26/2022	08/17/2022	12	1	2,060
L	09/23/2022	02/19/2023	12	1	5,149

why does your sample desired result have COST of 9,588? Shouldn't it be 7,209 (2,060 + 5,149 for two visits to clinic 12)?

Whitlea — Fri, 02 Aug 2024 15:11:42 GMT

Yes, you are correct! I apologize. These should be the results:

Clinic	Count	Other Clinic	Sum of Cost
3	1	12	7209
4	1	5	10501
5	1	4	13697
8	1	12	5149
10	1	11	5935
11	1	10	9588
12	2	3,8	11991

Re: Count with multiple criteria

Whitlea — Fri, 27 Sep 2024 17:45:47 GMT

Thank you Ksharp, this gave me exactly what I needed! Now I am trying to make a table that counts stays in a different clinic that considers the chronological order of the stays. I also want to add a readmissions column where readmissions= the count of movements/placements into a different clinic. I was able to modify your code to give me the correct client count for this but my readmissions and cost are being double counted for clients who have 2 back-to-back stays in the same clinic, followed by a stay in a different clinic. For example, client EE's readmission into clinic 4 is being counted twice where I only want it to be counted once as they only moved into a different clinic one time (from clinic 5 to clinic 4). Is there a way to fix this so it doesn't duplicate these readmissions and cost?

input client$	Span_Begin :DATE9.	Span_End :DATE9. clinic stay cost;

Re: Count with multiple criteria

Ksharp — Sat, 28 Sep 2024 06:47:53 GMT

Just add DISTINCT keyword before SQL,and use this dataset to calculate these readmissions and cost.

create table temp2 as
select distinct a.Clinic,a.Client,b.Clinic as _Clinic,b.Cost as Cost
 from temp as a,have as b
  where a.Client=b.Client and a.Clinic ne _Clinic and a.Span_Begin lt b.Span_Begin  ;
