I am trying to produce the date of the patients last mammogram. We use 2 different OBS terms and patients can have both. I tried this:
{IF LASTOBSDATE("MAMMOGRAM") == "" and LASTOBSDATE("BMAMSCRTOB")== "" THEN "No mammogram on file"
ELSE LASTOBSDATE("MAMMOGRAM") "+" LASTOBSDATE("BMAMSCRTOB")
ENDIF}
It seems to pulling the correct date, but if the patient had both shouldn't it produce both dates?
Thanks
Laurie

We actually use a function that allows us to pass it multiple Obs Terms and it will return the Obs Term with the most recent date and the value of that date.

OK, first I'll show you how we call the function:

fnUtilityGetMostRecentObsName(array("CHLAMYD CULT", "CHLAMYD DNA", "C TRACHO DNA"))

Here is the code for the function, it resides in the Utility library, so I do not know if this is something my predecessors created or if it is canned function:

{

local lCounter

local lSize

local lMostRecent

local lCurrentDate

local lDate

lMostRecent = 0

lSize = size(arrObsName)

for lCounter = 1, lCounter <= lSize, lCounter = lCounter + 1 do

lCurrentDate = LASTOBSDATE(arrObsName[lCounter]) /* Determine date of most recent value for this observation */

if (lCurrentDate <> "") then

if (lMostRecent > 0) then /* If there is another "valid" observation already found */

if (DURATIONDAYS(lDate, lCurrentDate) > 0) then /* If last date for observation is after last date for other "valid" observation */

lMostRecent = lCounter

lDate = lCurrentDate

endif

else

lMostRecent = lCounter

lDate = lCurrentDate

endif

endif

endfor

if (lMostRecent > 0) then /* If a valid observation has been found */

return (arrObsName[lMostRecent]) /* Return its name */

endif

return ("")

}
