DistinctCount per startdate

[RemiAnthonise]

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)

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.

Hi @v-xicai Amy,

Sorry to bother you with this but if you have time to check my issue, I'd really appreciate it.

Hi @v-xicai or someone else:

I'm getting close to the deadline I have for this report and I haven't found the solution yet. Can you help me with this one?

Thanks!

Hi @RemiAnthonise ,

You can create measure like DAX below.

Count=
SUMX (
    SUMMARIZE (
        Table1,
        Table1[Patient Code],
        Table1[Patient ID],
        "Result",
     Var d= CALCULATE(DISTINCTCOUNT(Table1[Patient ID]), FILTER(ALLSELECTED(Table1), Table1[Patient Code]=MAX(Table1[Patient Code])))
     Return
     IF(d>=2, d+1,d)
   ),
    [Result]
)

Best Regards,
