Hello,
I am trying to flag patients who had been given a medicine within 48 hours of admission.
Any suggestions are highly appreciated.
Count = DISTINCTCOUNT(query[24hourflag])-1
Example:
ID Admittime MEDTIME 24hourflag
101 01JAN2017 :1AM 01JAN2017 :11PM 101
101 01JAN2017 :1AM 02JAN2017 :6AM blank
102 08JAN2017:5PM 11JAN2017:5PM blank
Thanks
DISTINCTCOUNT counts ALL blanks as 1 distinct value
To get rid of the -1 use this measure instead
Measure = CALCULATE ( DISTINCTCOUNT ( query[24hourflag] ), FILTER ( query, query[24hourflag] <> BLANK () ) )
Thanks Sean, I will use the filter next time.
But can you explain what the -1 is doing in our previous formulae?
Thanks
Okay =>DISTINCTCOUNT counts ALL blanks as 1 distinct value
This means ALL Rows in the [24Hourflag] Column that are BLANK will count as 1 => meaning this 1 will be added to the Total
Say you have 5 distinct non-blank values => your formula without the -1 will return 6
because 5 distinct non blank + 1 for all blanks
so the - 1 deducts the blanks
Does this make sense?
EDIT:
Look at the picture....
DISTINCTCOUNT will return 3
without - 1 or the FILTER function filtering out the blanks
So it will group all the Non Blanks (counts all non blanks which is 5 in your example) and all the blanks(count will be 1 for all of them).
When we say -1 , it removes the group which has a count of 1?
Is that right??
