I am trying to calculate the FIB-4 score for a patient in a form. It uses their ALT, AST and PLATELETS. I get it to calculate successfully ONLY on my workstation, regardless of who is logged into Centricity on that workstation. On any other workstation it yields no result. I have a check box (document.calc_fib4) to click if you want it to calculate the value, and a field containing the obs term that is populated with that calculated value. If the check box is not clicked, I do see the value Blah in the obs term regardless of the workstation. Here is the relevant code. I have tried it in a variety of ways but to no avail. Any ideas would be much appreciated!

{!if document.calc_fib4 == "" then
  obsnow ("FIBROSISSCRE", "blah")
else
	obsnow("FIBROSISSCRE",
   fib_4(obsany("SGOT (AST)"),obsany("SGPT (ALT)"),obsany("PLATELETS")))
endif
}

fn fib_4 (ast,alt,plt)
{ 
local pltlen=match(plt,1," ")
if (pltlen=0) then
	pltlen=size(plt)-1
endif

	str(patient_age()*val(ast)/val(sub(plt,1,pltlen))* sqrrt(val(alt)))
}
{fn sqrRt(num)
{
	local nLow
	local nHi
	local nVal
	local nSqr
	local nErr

	if num = "" then return "" endif
	if num <> val(str(num)) then return "" endif
	if num = 1 then return "1" endif
	if num > 1 then
		nLow = 1
		nHi = num
	else
		nLow = num
		nHi = 1
	endif
		nVal = (nLow+nHi)/2
		nSqr = nVal*nVal
		nErr = nSqr-num
		if nErr<0 then nErr=-1*nErr endif

		if nErr>0.003 then 
			while nErr>0.003
				do
				if nSqr < num then 
					nLow = nVal
				else
					nHi = nVal
				endif
	
				nVal = (nLow+nHi)/2
				nSqr = nVal*nVal
				nErr = nSqr-num
				if nErr < 0 then nErr = -1*nErr endif
			endwhile
		endif
		nVal = round(nVal,2)
		nVal = str(truncate(nVal,2))

	return nVal
}
}

additional info - it is the patient_age() function that is the culprit, but why I don't know. It doesn't work whether I assume it returns a string or a number on workstations other than mine, and only works on mine when I assume a number

the patient_age function is in the mellib.txt file. make sure all workstations have the same mellib.txt file.

thank you

At least one other person for whom it doesn't work seems to have the file. Is there some way we need to point to it so that it knows to access functions in there? Assuming our forms know to access this file, can we add any functions we want there for general use?

if your workstations are all fat client, it should be in the Centricity folder. if your workstations are using Citrix, it should be in the Centricity folder on the Citrix server. shouldn't have to point to it in any way. you can add to the file, but it will be replaced with every upgrade. I have tweaked functions in the file, but I add comments at the top of the file stating which functions I've tweaked and how. I also keep a copy of the file separate, so it doesn't get overwritten with an upgrade and so I can compare what's changed with the upgrade.

hmm, that makes sense but everyone has the same mellib.txt file in the same place. Since patient_age() is a one-liner, I am using its code in my calculation and all is well. Will follow up with GE

Thanks!
