The UFN website uses an Apache web-server
and has a record of the web logs related to the site
visits since January 2006. These logs were initially
processed using Webalizer software (www.webalizer.
org) to calculate site hits, user logins and visits.
Telephone interviews with the computer departments
of each hospital were performed to
collect where each institution installed the hyperlink
to the UFN website, and screen-shots
illustrating the interventions were taken.
