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!
