Just wondering if anyone out there has a working auto BMI function. We currently utilize a calculation button to do this. A function that would populate the field once the height and weight are entered would be ideal.

I've gotten close, the field populates but only after swapping tabs.

If you can get your function to calculate the BMI correctly try something like this:

DOCUMENT.BMIGOESHERE = str(NameOFBMIFXN(heigh,weight))

}

You may just need to wrap your function call inside a watcher to get it to pull for you. We are doing something similar.

I attached ours to a button, so it populates the fields, prints out the BMI letter if the BMI is outstanding, and adds their BMI to the chart.

Within the form, I use the following calculation:

if (obsnow("Height") <> "" and obsnow("Weight") <> "") or (obsprev("Height") <> "" and obsnow("Weight") <> "") then

OBSNOW("BMI",str(fnCalcBMIConv(OBSNOW("Height"),OBSPREV("Height"),OBSNOW("Weight"))))

OBSNOW("BSA",str(((OBSNOW("Weight")/2.2)^.425)*((OBSNOW("Height"))^.725)*(71.84/10000)))

else ""

endif

I then use a Data Display field with New observation of "BMI".

Finally, I also use the following page close handler:

if PATIENT._AGEINMONTHS < 216 and PATIENT._AGEINMONTHS >= 24 then

If OBSNOW("BMI%ILE") == ""

Then ""

Else cond

case OBSNOW("BMI%ILE") >= 95 If match(toupper(PROB_AFTER("delimited")),"BODY MASS INDEX PED >/EQUAL TO 95TH % AGE")>0

Then ""

Else MEL_ADD_PROBLEM("DX OF","BODY MASS INDEX PED >/EQUAL TO 95TH % AGE","ICD10-Z68.54",str(._todaysdate),"","BMI Problem created from BMI% Calculation","","")

EndIf

case OBSNOW("BMI%ILE") >= 85 and OBSNOW("BMI%ILE") < 95 If match(toupper(PROB_AFTER("delimited")),"BODY MASS INDEX PED 85TH % TO < 95TH % AGE")>0

Then ""

Else MEL_ADD_PROBLEM("DX OF","BODY MASS INDEX PED 85TH % TO < 95TH % AGE","ICD10-Z68.53",str(._todaysdate),"","BMI Problem created from BMI% Calculation","","")

EndIf

case OBSNOW("BMI%ILE") >= 5 and OBSNOW("BMI%ILE") < 85 If match(toupper(PROB_AFTER("delimited")),"BODY MASS INDEX PED 5TH % TO < 85TH % AGE")>0

Then ""

Else MEL_ADD_PROBLEM("DX OF","BODY MASS INDEX PED 5TH % TO < 85TH % AGE","ICD10-Z68.52",str(._todaysdate),"","BMI Problem created from BMI% Calculation","","")

EndIf

case OBSNOW("BMI%ILE") < 5 If match(toupper(PROB_AFTER("delimited")),"BODY MASS INDEX PEDIATRIC < 5TH PERCENTILE AGE")>0

Then ""

Else MEL_ADD_PROBLEM("DX OF","BODY MASS INDEX PEDIATRIC < 5TH PERCENTILE AGE","ICD10-Z68.51",str(._todaysdate),"","BMI Problem created from BMI% Calculation","","")

EndIf

else ""

endcond

EndIf

Else ""

EndIf

I got to be missing something with this, because I get a load of MEL vomit when I plug a height and weight.

This working on form load, but then doesn't evaluate continuously. It's like it using OBSPREV the whole time.

I apologize, I did forget to include a function that we are using in the Code for the form and just now realized this as I was reviewing this today, so this works in conjunction with the code I previously provided:

{! fn fnCalcBMIConv(heightnow,heightprev,weightnow)

{

local heightval = ""

local weightval = ""

If heightnow <> ""

Then heightval = heightnow

Else If heightprev <> ""

Then heightval = heightprev

Else heightval = ""

EndIf

if weightnow <> "" then

weightval = weightnow

else

weightval = ""

endif

if weightval == "" or heightval == "" then

return ""

endif

if heightval <= 0 then

return str(0)

endif

return str(((weightval*1)/((heightval*1)*(heightval*1)))*703.0696)

}
