Hi, I have a function that collects all the tobacco use info in one place, to add to an assessment.

It works fine, but problem is, its fired from a data display, and if I add or change the meds, it doesn't update the Assessment unless I open the form again, to look at the display (and then it updates immediately).

Most Watcher functions will fire as soon as an OBS term changes, but I wonder how I can get this one to fire as soon as the med is changed or added?

Here is the Watcher code that pulls all the data together:

{fn SMKASM(var1,var2,var3,var4) {

SMOK_ASSESSMENT=

""

If (OBSNOW(

"SMOK STATUS"))<>"" then SMOK_ASSESSMENT=SMOK_ASSESSMENT + "Smoking Status: " + OBSNOW("SMOK STATUS") + HRET ENDIF

If (OBSNOW(

"SMOK ADVICE"))=="yes" then SMOK_ASSESSMENT=SMOK_ASSESSMENT + "Advice to quit tobacco use given today." + HRET ENDIF

If (OBSNOW(

"QUIT SMK STG"))<>"" then SMOK_ASSESSMENT=SMOK_ASSESSMENT + "Quit Stage: " + OBSNOW("QUIT SMK STG") + HRET ENDIF

If (CCC_sys_filter_meds(

"6210")<>"") then SMOK_ASSESSMENT=SMOK_ASSESSMENT + "Current Rx for Smoking Cessation: " + CCC_sys_filter_meds("6210") + HRET ENDIF

return SMOK_ASSESSMENT}

}

I have a Data display which maps the meds to an OBS term (but still no joy)

{OBSNOW(

"SMOKCESSMEDS",(CCC_sys_filter_meds("6210")))}

and here is the function call:

{IF (match(PROB_AFTER(),

"TOBACCO USER") > 0) then MEL_ADD_ASSESSMENT('DX OF','TOBACCO USER','ICD10-F17.200','C',str(SMKASM(OBSNOW("SMOK STATUS"),OBSNOW("SMOK ADVICE"),OBSNOW("QUIT SMK STG"),OBSNOW("SMOKCESSMEDS")))) else "" endif}

{IF (match(PROB_AFTER(),

"TOBACCO USER") > 0) then fmt("TOBACCO USER ASSESSMENT/PLAN:","B") + "

"

+ str(SMKASM(OBSNOW("SMOK STATUS"),OBSNOW("SMOK ADVICE"),OBSNOW("QUIT SMK STG"),OBSNOW("SMOKCESSMEDS"))) else "" endif}

Any advice would be appreciated. Thanks.

I would set a global variable equal to MEDS_AFTER()...

{!global med_at_load = MEDS_AFTER()}

then...

{if MEDS_AFTER() <> meds_at_load then

statements...update display...

endif}

Thanks for the suggestion; it didn't work but gave me the idea to do this:

{!OBSNOW("SMOKCESSMEDS",(CCC_sys_filter_meds("6210")))} in the functions list

and set the Data display to show:

{"TOBACCO USER ASSESSMENT/PLAN:" + "
" + str(SMKASM(OBSNOW("SMOK STATUS"),OBSNOW("SMOK ADVICE"),OBSNOW("QUIT SMK STG"),OBSNOW("SMOKCESSMEDS")))}

Since the function sends OBSNOW("SMOKCESSMEDS") as the fourth variable in the display, now it updates every time I change the meds.

Mysterious Watcher expressions!! - I still don't understand them completely, but at least this works...
