Prevention and screening recommendations have to be adapted on a regular basis to the latest scientific data and should be completed by tools made to facilitated the implication of patients in decision-making. The prevention and screening webpages hosted on the website of the Department of community medicine and ambulatory care of the University of Lausanne facilitate access to clinical recommendations identified by members of the five medical faculties in Switzerland (EviPrev national program), and to various information sources for physicians and patients, including patient decision aids. These webpages have been developed with primary care physicians who have participated in a pilot project in the canton of Vaud. The webpages have also been tested and welcome by a participatory group of citizen-users.
