look at the calculation line: ((140-AGE*BW:2D)/SRCR)*F}^CRCL;
If you don't have SRCR defined, you're dividing by 0, can't do it ->goodbye.
If your patient doesn't have an SRCR value, change the calculation line to
((140-AGE*BW:2D))*F}^CRCL;
This is the same as using SRCR = 1, a good "normal" value.
Then let your end users know that the calculation is using an assumed value =
1.
(Also, have your lab contact person give you an SRCR value for your TEST
patient so you can really test it.)
good luck,

I have opened a task with Meditech, but often this list is faster so I
am posing my question here too.
I am trying to create a new rule in PHA to calculate creatinine
clearance based on IBW instead of ABW. I basically copied our old rule
and modified it based on a rule example I had received from the list
before, but it is crashing to the desktop when I run it. Can anyone see
where I went wrong? We are Magic 4.9 Sr2.

When I order the med on a TEST patient the system kicks me out. My test
patient does not yet have a Serum Creatinine value. I would have
expected to see a message about no value, or unable to calculate, but
not kicked out.
