DistinctCount per startdate

Hi,

 

I have the following issue:

For a hospital I'm creating some dashboards. I want to calculate the amount of incoming patients per day. So, a patient comes in today at 3-12-2019 and stays for 3 weeks. He leaves at 24-12-2019. I want to calculate the amount of incoming (and outgoing) patients per day. But I DON'T want to calculate the complete amount of patients per day.

 

In this image, you'll see one patient incoming at 19-5-2017 at 00:00. I want to calculate this as 1. Then he gets a transfer, at 19-5-2017 10:15 to a different department. He gets a new Patient ID, because this is a new count. The Patient Code doesn't change. You see there's a new startdate. I want to calculate this as 1.

At 22-5-2017 12:45 he leaves the hospital, so there's an enddate. I want to calculate this as 1.

 

For 21-5-2017, I don't want to calculate anything as there isn't a mutation. How do I do this? Something with min() and max() dates? Something with firsdate() ? I think we have to Distinctcount the Patient ID since this is the unique record per row.

 

Thanks a lot!

    Hi RemiAnthonise ,

     

    You can create measure like DAX below.

     

    Count=
Var c=CALCULATE(COUNT(Table1[Bereken Van]), FILTER(ALLSELECTED(Table1), Table1[Patient Code]=MAX(Table1[Patient Code])))
Var d= CALCULATE(DISTINCTCOUNT(Table1[Patient ID]), FILTER(ALLSELECTED(Table1), Table1[Patient Code]=MAX(Table1[Patient Code])))
Return
IF(c>2, d+1,d)

     

    Best Regards,

    Amy

      Hi v-xicai  Amy,

       

      Thanks for your reply. This is not exactly what I'm looking for. 

      The outcome of your Count gives me 2 where I expect this: the sum of my Count is 23.

       

      I marked some rows in red: this is the same Patient (code) but a patient gets transfered. You see a change in the Bereken Van (startdate) and his Patient ID changes.

       

      In green, you see a patient without any transfers / changes in dates. He is there for 3 days so I only want to count this one as 1 on the 26th.

       

       

      What I want to create here is for all the incoming patients. When we have this I can change it to all the outgoing patients. That should be easy of we can solve this one.

       

      Hope this is clear.
