Background: In 1997 the German national nosocomial surveillance infection system (KISS) was established based on the NNISS methodology. 2001 KISS developed an IT-System to deploy a tool for the surveillance, called KESS. In 2005 a web based application (webKess) was implemented. The system supports the major KISS components.

Objective: To compare KESS to the web based system webKess.

Methods: To evaluate the systems, KISS developed a questionnaire. It was sended to all KISS-members who have the permissions to enter infections into webKess. The questionnaire contains 22 questions concerning the acceptance and the workload costs of the systems. The survey was processed with an online survey tool. It was a non-anonymous survey, the invitations were sent via email. Univariate analysis with statistical significance based on the Wilcoxon rank sum test for pariet samples was choosen to calculate the results.

Results: 467 KISS-members were invited to attend the survey. 280 answered the questions (55%). 167 participants have got experiences with both IT-systems (35.6%). 139 people are working with the KISS-module ICU-KISS and 101 with SSI-KISS. All answers except for the weekly count of logins are significant different between both systems. All users evaluate webKess as the more advanced surveillance system. The overall time working with the systems is reduced. The most explicit difference in the answers is the effort to create an own analysis including incidence rates (mean 1.7 for webKess and 3.0 for KESS).

Conclusions: It was unexpected that the weekly time investment is not as large as users told us. The good survey results confirmed the decision to introduce the web based system. Some of the benefits for KISS are no more efforts for analysis and the easy distribution of new functionality thanks to the center-based approach. The KISS-community is much more affiliated to the web-system.
