we run Openclinica on a win 2003 server in an evaluation scenario. I was wondering if I could provide links to an external PHP page where calculation of some score such as APACHE / Injury severity score are calculated. In this situation only the summary scores are required on the CRF. Ideally the score should be calculated on the CRF, but we already have an intranet site where all the calculations can be done. I wonder if providing a html link is possible on the CRF that takes them to the page for calculations and then permits the entry of those values on to the CRF.
