RETTS was initially developed in a hard copy format but is now also available online, thus decreasing the risk of loss of information.
RETTS is available as an online service as well as in paper format for those lacking an internet connection. More and more users are using the online function via www.retts.se. This service can be used online 24 hours a day, with no limit on the number of users per license. RETTS Online has the same approach and functionality as the paper version. An important difference is that RETTS Online enables the user to add their own local process steps in each ESS, which means there is an editing feature. The local “super user” must accept the license terms, and each license holder must appoint a medical officer with responsibility for the edited ESS.
